Wionczek Persisten codos los factores que explican la abrupta caída de los precios del crudo , ocurrida desde principios de 1986, y tal ,·ez no se disiparán durante los próximos diez años . Las pers• pectivas del mercado petrolero se ven agravadas por la desaceleración de la tasa de crecimiemo de la economía mundial. Freme a tan sombrío panorama, el autor plantea lo que , as.u juicio, debe hacer México, "uno de los participantes más recientes en el gran juego peuolero". Entre las propuestas destacan las siguientes: la actividad petrolera del país debe volverse más competitiva; el potencial de ahorro y conservación de energía tiene que apro-vecharse mucho mejor; frente a las persistentes dificultades de la balanza de pagos , cabe intensificar la producción interna de bienes de capital necesarios para el séctor energético y, por último, durante el resm del ckcenio no debe creerse que la crisis petrolera contemporánC"J es coyuntural y pasajera. Concluye subrayando la necesidad de que los países que dis~ ponen de-considerables reservas de hidrocarburos formulen una política petrolera a largo plazo.

Algunas reflexiones sobre el actual desequilibrio del mercado Roberto Gut/érrez R. En los ochenta se h:.m sucedido cambios muy import:rntes en el mercado petrolero mundial que aún cst~n lejos de concluir. Ello puede atribuirse a la disminución de la demanda oca· siona:da por la recesión económica mundial y la sustitución de fuentes energéticas, así como al aumento de l:i oferta, principalmente desde países que no pertenecen a la OPEP. En este [nbajo se analiza la formación de los precios del crudo en el período 1973~1981, cuando prevaleció un mercado de vendedores, con precios en ascenso, y en el lapso 1982•1986, significad.o corno un mercado de compradores, con precios a la baja. También se presentanlos fact0res t~cnicos, económicos y políticos que iníluirin en la determinación de los precios del crudo hasta fin de siglo. 702 Sección latinoamericana llondura!I f Un viStazo :i l.1. evolución reciente, p. 702 ■ Jnforme de la integración, p. 706 ■ Car12 de Buenos Aires / Al.AD!, p. 708 ■ Recuento latinoamericano, p. 712 ■ �17 Comercio &,:terior, vol. 36, núm. 8, agosto de 1986 7 l 6 Promoción de exportaciones Reflexiones sobre la experiencia coreana Marta Bekerman Se analiza la es1rategia seguida en Corea en los últimos decenios a fin de: promover las ventas en el exterior.

A. N. L,-- No. 1 EDITORIAL Bajo losmejoresauguriosnaceel 27 de Julio de 1977 el Centro de-Investigaciones Biológicas, de la U.A.N.L., en el seno de nuestra amada y querida Escuela, hoy Facultad de Ciencias Biológicas, que cumplió en el presente mes 27 añoI de su fundación, mismos que han transcurrido e!' impartir la Enseñanza, a más de realizar Investigación. si bien modesta, que dewe antaño se ha hecho, en ocasiones con la ayuda y simpatrá de las autoridades y en repetidas ocasiones, a pesar de las mismas. Los vaivenes políticos han afectado de diversas maneras el quehacer de la investigación, pero jamás han podido anularla, lo que signifícaríil atentar a la escencia de las carreras de BIOLOGO y de DUIMICO BACTERIOLOGO PARASITOLOGO que en si mismas implican a más de aspectos técnicos ylo docentes, la alternativa de formarse como investigadores, que tanto requiere el país en aspectos de: producción de alimentos, manejo óptimo de los recursos naturales, preservación de la salud pública, elevación del nivel nutricional de la población y tantos otros limitantes actuales del desarrollo nacional. Ambos tipos de profesionales se forman en la inquietud de buscar la verdad científica y poder aplicarla en beneficio de la Sociedad que patrocina y hace posible su existencia y funcionamiento. Podrá decirse que estiÍ saturado el "Mercado de Trabajo", en diversas profesiones pero, iAcaso hay manejo óptimo de los Recursos Naturales?, iTenemos buen nivel en salud pública?, por citar solo dos ejemplos; En tanto existan ese tipo de preocupaciones habrá demanda de Biólogos y de Q.B.P., porque la Sociedad requiere de su participación activa tanto a nivel de Investigación, Técnico como Docente. C.I.B. enhorabuena que surges como vocero del Centro de Investigaciones Biológicas de la Universidad Autónoma de Nuevo León, ya que indicas condiciones favorables para el desarrollo pleno de la investigación del Biólogo, del Qu/mico Bacteriólogo, en la Facultad de Ciencias Biológicas, fundada (1952) por el Dr. Eduardo Aguirr_e Pequeño, quién a más de ser Maestro Emérito de la U.A.N.L., (1916) ha sido un auténtico orientador del la Juventud del Noreste del pa/s y un visionario de los problemas nacionales y del tipo del profesional que debe formarse ante esas condiciones. En este devenir histórico, surge el Centro de Investigaciones Biológicas, no por caS11alidad, mas bien como consecuencia necesaria, por lo que de ninguna manera, será "flor de un drá': y si una etapa bien cimentada que deberá ampliarSP y superarse a futuro.

DESARROLLO DE PRACTICAS ACUACULTURALES (El present• es un compendtO de la conferencia dietada por el Biók,go Raúl Mart ínez Mata, durante el Curto de Metodologia de la Investigación Científica que auspicio la Dirección Gen•al da II Investigación Cientificl a tra• vés del Centro de Investigaciones Biológicas de la U,A.N.L., en el auditorio de la Facultad de Agronomía). La Acuacu1ru1a es fa técr1ica que permite el incremento de la producciÓr mediante el manejo de cultivos de especies, tanto de agua dulce como agua salada. Para aplicar dicha técnica funciona en forma autónoma un Departamento de Pesca institu (do durante el presente sexenio que de cumplir con sus metas fijadas, es probable que se llegue a convertir en Secretaría de Estado. La Dirección de Acuacultura depende del Departamento de Pesca, que junto con la Dirección de Infraestructura Pesquera y el Instituto Nacional de Pesca, controlan 50 centros a nivel nacional. Los Centros se dividen en Sub-Direcciones de Aguas Continentales y de Aguas protegidas. El Centro de Vallhermoso, Tamaulipas, funciona bajo el sistema de aguas protegidas, y su acción está enfocada a la Laguna Madre, de Tamaulipas. Los proyectos que se tienen hasta ahora son pocos y dependen de las con• diciones atmosféricas o climáticas, como son ciclones, épocas de prescripción, avenidas de los ríos, etc. El intento tia sido el de desarrollar la acuacultura a nivel básico, mediante un programa de inversión que se llama de Pesquerías Artesanales. El sistema Laguna Madre, formando por una serie de lagunas, posee una superficie aproximada de 215 hectáreas. Está limitado al norte por la desembocadura del Río Bravo y al sur por la desembocadura del Río Soto La Marina, que equivale a 180 kilómetros de litoral aproximadamente. Las principales especies de imp:,rtancia comercial en ésta área, son el camarón en primer lugar, le siguen las especies de escama, como son la Curbina, la Trucha, el Planter, la Carpa y el Tambor, entre otras, después están la Jaiba y el Ostión, que actualmente se explotan en baja escala . Las cooperativas que explotan actualmente el sistema suman 20. Sus ingresos globales al año son de 500 mil lones de pesos como producto de una captura equivalente a 9,500 toneladas anuales. Para aumentar la producción es necesario abrir más bocas hacia la Laguna con el fin de mantener una salinidad apropiada. Es cierto que existen nueve bocas naturales, pero sólo func ionan dos durante todo el año . La Secretarla de Marina contempla la apertura de otras dos, en la parte central, junto con éstos proyectos de inversión, hay otros que se denominan "Actividades del Sistema de Referencia" que tienen como fin elaborar un diagnóstico sobre et comportamiento de la Laguna. El objetivo principal es proteger el recurso natural llámese camarón o de escama, lo mismo que mejorar su calidad. Aunado al plan de diversificar la producción de especies, está el de incrementar la producción mediante diversas actividades experimentándose hasta 1a fecha pruebas satisfactorias. ARTES DE PESCA En la Laguna Madre se está elaborando u ria evaluación rielas artes de pesca , cuando son nocivas al ecosistema los pescadores son conscientizados por medio de pláticas para que las modifiquen. Está por caso las redes de arrastre que se utilizan en la Laguna para la captura del camarón, 1as redes tienen una longuitud aproximada de un kilómetro o de kilómetro y medio, con una luz de malla que permite sólo el aprovechamiento del 25 por ciento del producto total capturado, el arrastre lo hacen por medio de dos veleros, que independientemente de ello, los pescadores provocan un pavoroso daño al ecosistema, pues por una parte eliminan la fauna que acompaña al camarón y por otra, al hacer el arrastre remueven el fondo, impidiendo que Q"ezcan otras especies, como el ostión, que tienden a enterarse en el fondo de la laguna para su crecimiento. La sensibilización de los pescadores es imp:,rtante como medida básica para que vayan eliminando tales sistemas. hay otros problemas de tipo político de gentes que tienen fuertes inversiones en ta Laguna, y éstas no van a prescindir de los negativos métodos convencionales. No obstante el Departamento -de Pesca ha decidido eliminarlo, luego de sacrificar la Laguna por un período de 40 años; COOPERATIVAS Entre la serie de problemas que afronta el Sistema de la Laguna Madre, está el de las cooperativas pesqueras. De las 20 cooperativas que funcionan, sólo tres o cuatro son auténticas, las restantes fueron adquiridas por dos o tres ex-permisionarios, que tras de adquirir las artes de la pesca, registraron su cooperativa. Luego contrataron mano de obra barata, acarreando hombres que de hecho no eran pescadores. sino marginados de los Estados de San Luis Petos(, Veracruz y sur de Tamaulipas, que se convirtieron en objeto de inhumana explotación. Para citar un ejemplo, está el del camarón a los pescadores se les paga el kilo a cinco o diez pesos, a cambio de recibir víveres o refacciones para sus lanchas. La cooperativa o la supuesta cooperativa en cambio, lo vende a cien o ciento cincuenta pesos de tal suerte que 1os negociantes se ganan cerca de dos mil por ciento. Anta la situación anterior, el Gobierno Federal debe intervenir inmediatamente para poner coto a estos abusos. Las dependencias indicadas pueden ser el Oepartam€nto de Pesca y la Secretaría de Asentamientos Humanos y Obras Públicas. La tendencia debe ser regularizar la situación de· los pescadores en l::.a Laguna para formar auténticas cooperativas mediante la participación de auténticos pescadores, y no de empresarios perniciosos interesados en ganar enormes fortunas a costa de explotar la miseria de la gente.

Alanís Flores INTROOUCCION: La gran variedad de medios ecológicos, en los que se han desarrollado los distintos núcleos culturales de la humanidad, hasta nuestro tiempo, han pa$8Clo por diferentes.procesos culturales mediante los cúales han aprove• chado los Recursos Naturales a su alcance para sobrevivir; mediante actividades tales como: colecta de frutos y raíces silvestres, cacería, el establecimiento de técnicas agrícolas rudimentarias (uso de artes agrícolas); llegando hasta las modernas técnicas silvoagropecuarias.

Jo.Ecosistemas Inducidos, agrícola, pecuario, silvícola, de cuerpos de agua artificiales). Hablar de "productividad silvoagropecuaria" en nuestro medio, implica interacción relacionada con diversidad ecológica y cultural de los núcleos poblacionates inherentes a la misma, actualmente se ha conducido a la aplicación del concepto de "Sistemas", donde se trata de establecer una conj U\)ación de aspectos físico-biológicos y económico-sociales ligados a la producción. Es importante recalcar que al funcionar los sistemas de producción silvaagropecuarios o agrosistemas, como partes integrantes de un modo de producción dominante o de formas de producción dependientes, están supeditadas a normas ecológicas y antropocéntricas que condicionan su desarrollo. Considerando lo anterior, es de primordial importancia establecer criterios bien definidos, mediante estudios interdisciplinarios con una pla• nificación operacional equilibrada y con propósitos comunes. ESTRATEGIAS FUNCIONALES: Hablar de "ecosistemas productivos" en el estado de Nuevo León, es hablar de actividades agrícolas, ganaderas, uso de los recursos forestales y de la fauna silvestre, ecosistemas fuertemente perturbados debido a las distintas formas de explotación inadecuadas. Por lo tanto es importante el establecimiento de una gama de posibles alter'lativas que puedan ser aplicadas a las condiciones de nuestro Estado y que deberán de ser fundamentadas, en un marco de uso real y racional de los recunos productivos y sus limitaciones existentes. El plantear estrategias a corto, mediano y largo plazo, deberán ser tratadas mediante objetivos reales donde se contemplen tres niveles de análisis y diagnóstico, como son el ecológico, el económico y et social como a continuación lo enmarcamos: Al Es importante plantear primeramente un estudio fisiogratico completo de nuestro Estado como marco de referencia se ubiquen y localicen los recunos naturales, además esto servirá como base para conocer la evaluación y factores del medio que interactúan y condicionan la situación de los recursos existentes, (Uso de Sensores Remotos; Información proporcionada por DETENAL, cartográfica, fotográfica y Verificación directa en el campo). B) Establecer en base a informaciones física y biótica una Zonificación Ecológica, donde se ubiquen los ecosistemas existentes ya sean naturales o artificiales . C) Analizar los factores productivos de los ecosistemas y en base a el diagnóstico que se haga de los mismos, establecer estrategias de desarrollo, donde se planteen y se cuestionen los niveles críticos para armonizar los variantes que interactúan en el uso de los recunos y la productividad de los mismos. D) Recabar y analizar la información económica y social de las áreas de estudio en base a fuentes estadísticas y además como una fun ción muy importante será la de recabar información directa en el OEFINICION OE LAS UNIDADES ECOSISTEMICOS EN BASE A LA RELACION CLIMA-SUELO-VEGETACIDN.

EN EL AUDITORIO DE LA FACUL TAO DE AGRONOMIA, LO CUAL SERA PRESENTADA EN PARTES/. r INTRODUCCION, Por un tiempo se creyó que el problema tecnológico de los países subdesarrollados era que la dosis de tecnología era muy baja . En arios recientes ha recibido más atención la idea de que la tecnología ha tenido efectos perve~os por raZOnes mucho más complicadas que el problema financiero de adquirir tecnología . Se ha reconocido también la necesidad ineludible de crear una base científica para apoyar el desarrollo tecnológico. En los países subdesarrollados, el cambio tecnológico ha consistido, básicamente, en un proceso de transferencia de tecnología que ha creado demandas de fuerza de trabajo calificada escasa, y una aguda polarización o "dualismo" productivo. La adopción de métodos de producción mOOerno ha dejado fuera de los mercados laborales al grueso de la población no ·calificada. El cambio tecnológico es proceso de largo plazo, más aún cuando se considera que el grueso de los cambios técnicos está incorporado en el equipo y los métodos de producción. La sustitución rápida de tecnolog ia extranjera por ta nacional es un proyecto irrealizable para países que han mantenido un crecimiento industrial sustentado en técnicas y equipo suministrados en el exterior. La planta productiva adquiere una inercia tecnológica dificil de contener. También, la base científica y tecnológica nacional carece de la capacidad para producir tecnología y bienes de capital. La autosuficiencia tecnológica es meta utópica. Sin embargo, es posible actuar en la dirección de crear cierta autonomía, definida corr.o !a capacidad para de· cidir y seleccionar técnicas adecuadas a las con- diciones de un país. E::I proceso de inversión o formación de capital es entonces clave en cualquier poi ítica de reorientación tecnológica. Para muchos, la solución al trauma tecnológico de los países sulxlesarrol1ados se logra mediante la planificación de la Ciencia y Tecnología en todos los ámbitos de la actividad económica, es decir, mediante un plan global de desarrollo, donde la ciencia y la tecnologia sean el centro de la transformación económica poi ítica y cultural. En esta concepción la ciencía y la tecnolog ia son de hecho la solución al subdesarrollo mismo. Sin embargo, el afán planificador, aparte de pretencioso, nunca llegó a tener bases teóricas sólidas, ni en la teoría económica �ni ·n la de la planificación. t::n este trabajo se hace una evaluación crítica de la posibilidad de planifi car la ciencia v la tecnología en un marco de acción más modesto y se describen tos principios adoptados para elaborar et Programa Nacional de Ciencia y Tecnología de México, 1978-1982 11 LA TEORIA ECONOMICA Y EL CAMBIO TECNOLOGICO. • La literatura sobre crecimiento económico. hasia muy recientemente, práctiamente ha ignorado el cambio tecnológico, 1/ y puesto atención principalmente al proceso de acumulación de los insumos necesarios para lograr el crecimiento. · Según Schmookler, el estudio del cambio técnico es la "terra incógnita" de la economía moderna . . . ni siquiera nos ponemos de acuerdo en qué términología usar 2/ Se.gún otros" .. _ nuestro conocimiento historiográfico y social de la tecnología no satisface las necesidades de~la poi ítica. Las ideas suelen ser ingenuas y contradictorias en cuestiones teóricas tales como "técnica y tecnología", "inversión e innovación" v, sobre todo, en la relación todavía mística entre ciencia v tecnología'' 3/ 1/ 2/ 3/ Una técnica es una combinación dada <Je insumos para producir un producto. . El coniunto de todas las técnicas disponibles como resultado de la experiencia o la in· vestigación, lo que cambia es la tecnología Aún cuando la ttcnologfa no cambie, la tecnica puede cambiar si los precios de los factores de la producción cambian. (Como resultado de cambios en la dotación de factores en la economfa o debido a poi/ti· cas fiscales ( impuestos y subsidios} o pro• teccionistasJ. S. Schomookler, lnventtOn end Economic Growth, Harvard University Press, 1966. E. Layton, "Conditions of Technological Development", en lma-Spiegel-Rosing y Derek de Solla Price, Science, Teehnology 1nd Society, Sage Publications, London, 1977. La pregunta central es saber la importancia del cambio tecnológico en el proceso de desarrollo económico. El estudio del cambio técnico de hecho empieza con Marx y Schumpeter. En la década de los 50 la investigación empírica en los países industrializados mostró que el cambio técnico es el factor más importante que deter• mina la tasa de crecimiento de la economía 4/ Los intentos de clasificación (Hicks, Harrocl) del cambio tecnológico en neutro o en ahorra• dor de capital o mano de obra tiene, entre otros propósitos, el de conocer el efecto del cambio tecnológico sobre la distribución del ingreso entre los factores de la producción. Poco o nada se conoce hasta ahora sobre el efecto del cambio tecnológico en la distribución del ingreso per1onal. En esta sección hacemos una breve reseña de los distintos enfoques que estudian la manera como se origina éste. Además se hace un breve resumen de la discusión sobre la posibilidad de los pa ises subdesarrollados de emplear técnicas distintas a tas de los países industrializa• dos. Transmisión dtl cambio tecnolótico Por lo que se refiere a la manera de cómo el cambio tecnológico se transmite, la mayor parte de los modelos de crecimiento •económico no especifican ningún mecanismo especial de transmisión. Cómodamente se supone que el progreso técnico cae del cielo como "maná". 4/ E. F.

El efecto del progreso técnico se representa CO· mo un término más en la función de producción Ene término representa todos los fac. tores q ue sirve11 para c.!esphu:ada. En este tipo de 3nálisis no se sabe de dónde proviene el progreso técnico y, más sorprend,mte aún, es i[idependien te de la tasa de acum1..1lación de capital 5/ o dP. cua!qui!:! r otra variable del sistema econó mico, ~· ¡¡::lemás no tiene ningún costo. En e<stos modelos se dice que el cambio tecnológicc no está incorporado ldesembodied). En moc!P,los recien.tes más complicados a1 progreso tecnológico se concibe corno incorporado {embodied) en la nueva maquinaria, así la inWrsión es el mecanismo trasmisor de las innovaciones. En estos últimos modelos el cambio técniC:o pracede a una tasa constante que sólo afecta los nuevos bienes de capital 6/ Estas ideas sirven de base a los modelos de cosecha (vintage) que permiten, contrariamente a los modelos de cambio técnico no incoprorado, 7 / estimar la contribución relativa de la acumulación de capital y del progreso tt!cnológico al crecimiento de la economía. · 5/ R.M. Solow, "lnvestment an<i Technical Change" en i<. Arrow y K. Karlin, P. Suppes, (Compiladores) ; Mathematical M•· thods in the Social Sciences. Standford, 6/ E.S. Phelps, 'The New Vlew of lnvest• ment; A Neoclassical Ana/ysis", Ouartwly 1960. Jour,.I of Economics, 1962. 7/ Los esrudios empíricos basados en la noción dr cambio tecnológico· exógeno no incorporado encuentran que la mayor par· te del crecimiento económico no puede ser explicado por los aumenros observados de los insumos, en particular por la acumuleción del capital. De aquí que la explica· ción del crecimiento queda como un "residuo" atríbuible al progreso tecnológico. Aún cuando en este enfoque el cambio tecno· lógico es exógeno, parte de este cambio está in• corporado en las nuevas máquinas . De esta ma· nera una máquina capta la tecnología más re· ciente hasta el d ia de su cor1strucc1ón (vintage) pero no incorpora desarrollos posteriores en la tecnolog ia. Aunque la hipótesis del cambio tecnológico incorporado es un paso adelante, aumenta considerablemente la complejidad del análisis, ya que generalmente no es posible juntar !agregar) máquinas de diferentes cosechas (vintages) en un índice global que mida el acervo de capital con que se cuenta. El orlg1n del cambio tecnológico. La mayor parte de los modelos de crecimiento suponen que el cambio técnico es exógeno,aunque también se sostiene la tesis de que el cambio técnico es causado por factores dentro del sistema económico. Según Hicks 8/ "un cambio en los precios relativos de los factores de la producción estimula la inversión en general y la invención de un tipo particular va dirigida a economizar el factor que se ha encarecido rela• tivamente más'' . Esta observación surgirió la distinción entre invenciones "inducidas"' e invenciones "autónomas". El punto de vista de que el precio relativo de los factores imprime un sesgo tecnológico en favor de alguno de los factores de la producción ha sido rechazado con el argumento de que "el empresario está interesado en reducir los costos totales y no en los costos de la mano de obra o del capital. Cuando los costos por con• cepto de la mano de obra aumentan , cualquie1 cambio técnico que reduce los costos totales es bien recibido. Es irrelevante si esto se logre porque se usa más o menos capital o mano d E obra" . 9/ SI J. R. Hicks, The Theory of Wages, 2a. Establecimiento de un sistana de manejo de plagas y enferr,edades del manzano del Etlo, de N, L, POR : BIOLOGO M.C.FILIBERTO REYES V. 1 :1 81~8~8 ~--~-- .íbNlG~1~'i~:t~~E~: El cultivo det manzano en un frutal es de gran 1mp0rtancla económica en el Estado de Nuevo León, encontrándose la mayor superlflcle semt>rada en los Municipios de Santiago y Gatea na Nuevo León. No obstante ta relevapcla del aqroecoslstema, ha recibido poca atenclon por parte de los progra· mas oflclales y debido a esto, la Producción se ve abatida en función de un conjunto de factores como Pobre o nula fertillzación, Podas inadecuadas, ausencia de riego y Prlnclpalmente plagas y enfermedades que atacan a la plar}ta en sus diferentes Partes vegetativas como ratz, tallo, hoja, flor y fruto. En base a lo anterior, el presente proyecto tiene como objetivo prlnclpa 1, el de obtener la lntor• maclón bá-sica para Integrar los métodos de con• trol mas adec.uados, y de esta manera evitar pérd.ldas económicas producidas Por los Problemas Parasltológlcos. Para lograr este objetivo, la metodologia general del estudio se base en tres lineas de Investiga• clón que son las siguientes: 1- Determinación de umbrales económicos para cada Plaga y enfermedad. 2- Selección de Prasltlcldas efectivos, Que sean dal"linos para 1a plaga y/o fltopatógeno, e lnócuos para el complejo de organismos be• néflcos en el agro:ecoslstema. 3-Dlnlirhlca de poblaciones y determinación de los prJnclpa1es tactores ambientales que causan las fluctuaclones. Para lograr los fines que se han Planteado se reQuiere de un mínimo de tres años de estudio, Y en este año se e.¡tá trabalando con las siguientes plagas y enfermedades, Palomllla de ta manzana Usi:a,yresia pomonella, PUigón \anigeno Erloso• ma lanlgem.fm, Frailecillo Macrodactylus sp., Y ro,-o jel manzano Venturia inuqualls. .,..As parcelas experimentales se tienen tanto en Galeana como en Santiago, N. L, en los ejidos 18 del marzo y calabaclllas Para el Primero y San Juan Bautista y Laguna de Sánchez para el segu11do respectivamente. Para la determinación de umbrales económicos, se están tomando registros de las densidades P0· blaclonales de las Plagas, Que Junto con los da· tos de producción y el costo del control, nos dara en una forma mas o menos precisa el um· bral económico. Con respecto a los ParasltJcldas, se están ensa• yando actualmente 12 Insecticidas . diferentes para el conlrol de la palomllla, pulgon y fralle• cilio, además de cuatro fungicidas Para et con• trol de la roña. Para selecclonar el mejor se va a tomar en cuenta su efecto en los organismos benéficos, costos y Producción del cultivo. En lo Que se refiere a la dlnimtca de poblado· nes, se estan muestreando. las Poblaclones de las diferentes plagas y enfermedades. Dichas fluctuaciones se van a correlacionar con los datos de temperatura máxima y m(nlma, humedad relativa que está registrando un hl9rotermógrafo Y un termómetro de máxima y m1nlma QUe se tle• ne en cada área de estudio. El proyecto en general se esta canalizando a través de tesistas tanto de la carrera de Biólogo como de Q.B.P., Participando 13 de Biólogos Y 2 Quimlco Bacteriólogo Parasitólogo. Por otro lado, el proyecto también esta brindando la oportunidad a 13 alumnos de semestres supe• r¡ir~flll~fe~~r:i~~'a~~ J~ ~J:~flio ~ec~6bfa~ ciones, aPllcaclón de plagulcldas, ordenamiento de datos e incluso análisis e!>tadistlcos de los mismos.

El 9 de noviembre de 1979 tuvo lugar una reunión de Directores de Programas de Investigación en Zonas Aridas en el Laboratorio del Desierto del Bolsón de Mapimí, Durango. Patro• cinaron el encuentro el Instituto de Ecología del Museo Nacional de Historia Natural de la Ciudad de México, el CONACyT y el Gobierno del Estado de Durango. El nombre oficial de este centro de estudios científicos y tecnológicos es: LABORATORIO DE INVESTIGACIONES BIOLOGICAS DEL BOLSON DE MAPIMI, ubicado al Nordeste de Ceba11os, casi en el punto geográfico en donde confluyen los límites interestatales de Chihuahua, Coahuila y Durango. Destacan, entre los objetivos de la Reunión de referencia: a) El intercambio de ideas entre los directores de programas con el objeto de establecer una mas estrecha coordinación y cooperación entre los diferentes centros e instituciones que· trabajan en problemas de las zonas áridas de México. b) Diseñar posibles mecanismos regulares de consulta e interacción. Esto con el fin de evitar el aislamiento en que suelen operar algunos centros de educación superior y de investigación ligados a los problemas del campo. c) Fomentar la investigación científica de alto nivel en aquellas áreas de la ciencia que más ligadas estén a los problemas bióticos y recursos naturales del propio Bolsón de Mapimí y de extensiones similares del norte de México. Destacan entre esas disciplinas la Zoología, la Ecología y la Botánica, pero también interesan la Geología y Edafología, la Demografía de plantas, el Manejo de Pastizales y otras. El Laboratorio del Desierto (designado así para abreviar) fue dotado de 20 Has. inicialmente, gracias a donativos filantrópicos de ganaderos y propietarios de predios del área. Cuenta con una pista de aterrizaje de avionetas y helicópteros, y sirve de referencia para el tráfico aéreo el Cerro de San Ignacio, promontorio que rompe la monotonía de una extensa 11anura desértica. PAGINA 2 Se cuenta con la cooperación científica de varias instituciones nacionales e internacionales. Así por ejemplo hay proyectos que han merecido el patrocinio del programa "El Hombre y la Biósfera" que auspicia la UNESCO. Se estableció una estación meteorológica en el Laboratorio del Desierto. Se han suscrito convenios con el Instituto Nacional de Investigación sobre Recursos Bióticos (INIREB) con sede en Jalapa, Ver. Asimismo se ha fortalecido el nexo con la Escuela Nacional de Ciencias Biológicas del l. P. N. ; existe apoyo del Instituto de Biología de la U . N.A. M. , de la Universidad Autónoma Metropolitana y del Núcleo Universitario de la Universidad Juárez del Estado de Durango, con sede en Gómez Palacio. CASA NUEVA ESTILO COLONIAL Se cuenta con una casa muy amplia de patio central con arcos y pasillos estilo colonial. Ahí se alojan los investigadores residentes y visitantes, quienes disfrutan de amplia estancia de cómodo mobiliario, servicio de cocina, limpios dormitorios y facilidades en equipo e instalaciones básicas de los laboratorios para el procesado del material biológico. El Laboratorio del Desierto es considerado como un potencial Centro de educación, capacitación y entrenamiento científicos de primera fila en México, del que podrán hacer uso los especialistas que intervengan en los programas de investigación que ya están en marcha y aquellos que se suscriban posteriormente. Una característica que se hace notar es la tendencia al trabajo interdisciplinario, en equipo, especialmente en todo lo concerniente a la conservación y manejo de los recursos naturales de la región y al conocimiento de la flora y fauna del extenso Desierto chihuahuense, unidad biogeográfica de la que el Bolsón de Mapimí forma parte. INVESTIGACIONES EN MARCHA Entre los tópicos que se discutieron brevemente en la reunión merecen citarse los siguien· tes: "La Reserva de la Biósfera de Mapimí", tra• bajo que comprende estudios ornitológicos, espe- cialmente sobre falconiformes (solamente "aguilillas"), así como estudios herpetológicos (en lacértidos), investigaciones sobre acrididos y tetigónidos (chapulines) así como en ecofisiología de insectos. Entre los trabajos más notables, ya publicados, merece especial mención el de Martínez Ojeda, E. y J. Norello . 1977. "El Medio Físico y las Unidades Fisionórruico-florísticas del Bolsón de Mapimí". lnst. de Ecología Publicación No. 3. 63 pp. Se añaden estudios sobre forrajes silvestres, microclimatologia, guaridas de roedores y enclaves arqueológicos y antropológicos. SE POSTULAN HIPOTESIS Se ha partido de dos hipótesis de trabajo para lidiar con las poblaciones vegetales y animales del Bolsón, enunciadas como sigue: a) Hay una tendencia en las comunidades bióticas naturales del desierto a aumentar su diversidad especifica en función de su antigúedad (su carácter histórico). b) Hay alta diversidad de especies debido a la alta selectividad ambiental que impera en el desierto y a una baja competencia interespecifica. Durante la reunión se dejaron sentir inquietudes por ampliar las perspectivas, como serian las pesquisas sobre las interacciones ecológicas, la fisiología de las especies, su comportamiento, la estabilidad del ecosistema, así como aspectos acerca del potencial reproductivo, sexual y asexual, de muchas especies. ASPECTOS HUMANOS Se virtieron datos en el sentido de que el 71.6% del territorio nacional es considerado como árido y semiárido, es decir las 2/3 partes de la superficie continental de México. Tal extensión desértica o semidesértica cuenta con 27 1/2 millones de habitantes, según datos oficiales. Estos compatriotas se distribuyen en 63,000 comunidades rurales que necesitan agua para subsistir. Esto significa que merecen atención oficial con miras a resolver -siqÜiera sea parcialmente- sus necesidades y e11o conlleva acelerar programas de desarrollo por regiones . De ahí que se haya puesto tanta atención por parte de agencias gubernamentales sobre las especies vegetales úties que constituyen recursos reales de subsistencia para la economía campesina, tales como las comunidades que dependen del ixtle de lechuguilla y "palma", de la cera de candelilla y otras plantas (nopales, magueyes, biznagas, etc.). URGEN LAZOS DE COOPERACION INTERINSTITUCIONALES Se enfatizó la importancia de avalar la infraestructura científica del país, así como sus bases técnico-académicas, pero sobre todo la urgencia de establecer coordinación entre todas aquellas instituciones que comparten responsabilidades tanto nacionales como estatales . Así pues, es preciso aprovechar al óptimo estos cen- Instituto del Desierto, reserva de la biósfera, Ma• pimi, Dgo. (Zona del Silencio). tros de investigación para preservar nuestro pa• trimonio en materia de recursos tales como la jojoba, el guayule, la candelilla, la cañagria y otras. EL STATUS LEGAL DEL LABORATORIO DEL DESIERTO Durante la explicación que se nos proporcionó acerca del "status legal" de los terrenos cedidos al Laboratorio del Desierto, trascendió que se trata de 9,000 Has. cuya venta fue un trato simbólico. Se legalizó la venta por un Decreto del Congreso del Estado de Durango. Asimismo, se dio lectura al protocolo jurídico que ampara el establecimiento permanente del Labo• ratorio del Desierto, el cual se inició con una promesa de donación de aquellas primeras 20 Has. que se citan al principio de este reportaje. Se afirmó que éste es una prueba más de la confianza que debe imperar entre campesinos, gobernantes y científicos. PLANES A LARGO PLAZO Por otra parte se insistió en la importancia del fomen'to ganadero mediante el mejoramiento genético de aquellas razas mejor adaptables a las condiciones imperantes en el Altiplano Mexicano. Para ello deberán seguirse estu• dios sobre modelos de producción pecuaria, prácticas de inseminación artificial, etc. Acerca del Desarrollo Ganadero de Mapimí se afirmó que, contrariamente a lo que ocurre con la devasta· ción del trópico mexicano por los desmontes con fines pecuarios, en el árido mexicano se pueden seguir intensificando las explotaciones extensivas de ganado fino, así para carne como para leche. Por raíces ancestrales la Botánica existe como disciplina empírica . La etnobotánica se desarrolla al amparo de la medicina vernácula, pero hacen falta estudios comprensivos, más actua• !izados, acerca de las plantas útiles de las comunidades rurales del árido.

Los requerimientos climáticos del Algarrobo resisten al frío (-5• C) y a la sequía hasta (47 9 C), siguiendo la línea del naranjo. Por tan especiales cualidades, el Algarrobo ha llamado la atención en el campo de la Agri· cultura; la Ganader!a, la Industrial; la Medicina; y en la alimentación del hombre y de los animales de granja y como un verdadero recurso auxiliar en el Control de la Contaminación Ambien• tal -Smog- Smoke humo y Fog, niebla. Más de 60 variedades de Algarrobo son conocidas en España; sin embargo, solo un9s l 5 son las que más se prefieren, según las cualidades que correspondan a los fines que el interesado se proponga desarrollar. De las que disfrutaron de estas cualidades solo nombraré algunas de ellas, como: Bleda, Casudas, Caches, Chopos, Costilla de Asno, Delplomale, Lisas, Meleras, Negras, Roja, Silvestre, Vaina de Puñal, Vara larga y Valenciana. Sin embargo en estos últimos años, algunos autores opinan que son poco numerosas las va• riedades cwltivadas en Italia, Grecia, España y el mediodía de Francia, las que se reducen a las siguientes: la la. Algarrobo silvestre, macho y por lo tanto estéril y no sirve más que para patró1;1 o para fecundar las plantas femeninas (no olvidemos que como planta de ornato sería pre- PAGINA 4 (CERATONIA SILICUA L) "Pan Gonzalitos" ferible en ciertas circunstancias, nota del Dr. E. A.P.). 2o. Algarrobo franco, también silvestre de producción temprana . 3o. Algarrobo macho, de frutos fibrosos bueno para la alimentación de equinos . 4o. Algarrobo hembra o azucarado, llamado por Risso, Ceratonia silicua latissima que se cree corresponda al Algarrobo de España, aunque menos fructífero que el anterior, produ· ce legumbres gruesas y largas, pulposas y dulces "que se venden en el comercio hasta para ali• mento del hombre. Se señala la importancia de la propagación del algarrobo por semilla o por injerto (yema, parche, estaca o corona), según lo requieran el , patrón o las condiciones del árbol . Las semillas tienen un poder germfnativo· de l a 3 allos. Se J Plantitas de Algarrobo, en vivero .,,.¡,et !mental del Dr. E. Aguirre Pequeño en 1950. conservan con la silicua y rara vez se siembran de asiento, en este caso, poniendo 4 a 5 y dejando luego una sola plantita. Generalmente, se hace la siembra en semillero (almáciga). Las semillas tomadas de las vainas recientemente maduras, germinan con facilidad, las semillas que se secan adquieren una dureza como de piedra y germinan muy despacio (a veces hasta después de un año) a menos que se raspen con papel lija; al· gunas soluciones ácidas correrían el riesgo de deteriorar el embrión. Lo más recomendable consiste er. mantener las semillas en maceración en el agua durante dos o cuatro dlas; cambiando el agllll diariamen• te teniendo !JI ptecaución de sacar del agua las (lúe van preséntando un hinchamiento, es decir ., u11. vol~men doble a triple de la semilla antes de p~meria en m!l,ceración; a fin de que el exceso de humedad en las siguientes horas no llegue a deteriorar o dar muerte al embrión de la semilla. Las semillas aumentadas de volumen -de acuerdo con mi propia experiencia- las voy separando para ponerlas en recipientes donde "-Ontinúan en la humedad entre dos esponjas o en cajas pla• nas con fondo sólo húmedo ya mediante espon• jas o algún otro material como algodón y en unos cuantos días más -dos a cinco- aparece un puntito blanco anunciando el inicio de la ger• mi nación radicular (nota del Dr. E. A . p.). Las semillas que fueron seleccionadas ya dispuestas a germinar pueden plantarse en cajoneras que contengan vermiculite (el que ésto escribe ha usado el aserrín previamente esterilizado mediante soluciones comunes bien conocidas o sim• plemente con agua hirviendo a fin de eliminar los hongos o larvas que pudiera contener (nota del Dr. E.A.P.). Oportuno es recordar que de estas semillas se desarrollarán en el futuro produciendo plantas dioicas en la mayoría de los algarrobos o monoica s y autofertilizantes romo la variedad Bolser. Es suma el sexo de la planta depende de la semilla o el que mejor convenga mediante la prác• tica del injerto. Las camas o recipientes en donde han sido plantadas las senrillas, se mantienen bajo sombra parcial; cuando tienen ya cuatro hojas, las plantitas se cambian a macetas pequeñas; cuando ere• cen a una altura de 15 cm., se trasplantan, a macetas mayores; al llegar a una altura de 76 cm., se injertan, en las mismas macetas, o se siembran en el campo, para ser injertadas en las ramas, al llegar a los dos años de edad. . A propósito me he extendido en la propagación ya que es lo que más nos interesa, porque es bien sabido que la semilla es muy difícil obte• nerla .

L tura y Recursos Hidráulicos, los requisitos que se requieren para la obtención de material, consiste no sólo en semilla, sino también en arbolitos que están al alcance de sus posibilidades como lo advertiremos al fin de este resumen. El Algarrobo florece en otoño -julio y agosto- y da fruto al año siguiente. Las vainas an, tes verdes; cuando han madurado tienen un color castaño; antes de almacenarlas se sacan al sol varios dlas hasta que se sequen. Antes de finalizar el trabajo se intenta una breve reseña histórica acerca de la introducción del Algarrobo en los Estados Unidos aunque sin éxito la primera vez en 1854. Así como en la segunda ocasión en 1949 con verdadero éxito gracias a los doctores Rittenhouse de San Diego, .California quien se propuso establecer una Estación Experimental para el cultivo y divulgación del Algarrobo así como gracias al conocimiento cientffico y técnico del Dr. J. Eliot Coit a quien debo la experiencia en el cultivo de tan : preciso recurso que viene a sumarse a nuestra flora de Nuevo León. El Algarrobo como un extraordinario recurso en el control de la contaminación -Smog-. Puesto que nuestra ciudad de Monterrey, está reconocida como la capital industrial de Méxi• co, la contaminación ambiental constituye un verdadero problema para la salud pública, de aquí que el cultivo del Algarrobo por sus cualidades antes expuestas constituye una verdadera necesidad la que no se impone al mí!rgen de la acción del hombre sino por medio de ella. Este hermoso árbol siempre verde, vendría a constituir para nuestra ciudad a manera de un pulmón sano, vigoroso -y permanente. En Inglaterra llaman al A1garrobo con e1 PAGINA 5 �nombre vulgar de Johnsbread (Pan de Juan); en . los Estados Unidos y otros países con el de St. John's bread (Pan de San Juan).

CONCLUSIONES la.- El cultivo del Algarrobo Ceratonia silicua L), se inició por el suscrito Dr. Eduard0 Aguirre Pequeño en el Cañón de la Huasteca, Tylunicipio de Santa Catarina, N. L., en 1950. 2a.- El Dr. J. Eliot Coit Ph. D. Fue nombrado Investigador Huésped del Instituto de Investigaciones Científicas de la Universidad de Nuevo León, por el director del mismo en 1953, Dr. Eduardo Aguirrq Pequeño. 3a.- Con fecha 2o. de junio de 1953, el Dr. J. Eliot Coit, rinde un informe acerca de las plantas frutales principalmente que podrían cultivarse en Nuevo León. Al referirse al Algarrobo (Ceratonóa silicua) expresa: que "es un árbol que ciertamente debe ser ex'perimental en Nuevo León". 4a.- En 1970, le fue proporcionada semilla de Algarrobo (Ceratonia silicua L), al biólogo M.C., Jorge S. Marroquín, Jefe del Laboratorio de Botánica de la Facultad de Ciencias Biológicas a fin de llevar a cabo investigaciones relacionadas con la germinación y desarrollo de la planta, las que logró con todo éxito, habiendo distribuido las plantitas ya desarrolladas a quienes lo solicitaban. De aquellas plantitas podemos observar ahora árboles robustos y frondosos. El Biólogo Adolfo González Castilla, a quien le doné semillas para el mismo objeto, logró también observar desde la germinación de la semilla hasta el crecimiento de buen número de árbolitos de los que algunos de ellos han sido plantados en la Ciudad Universitaria. 5a.- Después de 30 años de experimentación por el que ésto escribe, Dr. Eduardo Aguirre Pequeño, miles de plantas desde las más pequeñas que al desarrollarse en viveros, hasta los más frondosos árboles rindiendo cosecha, se encuentran en diversos municipios del Estado de Nuevo León, como en la Huasteca, Municipio de Santa Catarina, hoy ciudad; en el Municipio de Hualahuises mi tierra natal; en donde he puesto especial atención, proporcionando se!Ilil!a y arbolitos que lucen en la plaza prmc1pal y en las huertas de los vecinos; en el Topo Chico; Villa de Santiago, Linares, Marin, en las Estaciones Experimentales de las Facultades de Agronomía y Ciencias Biológicas asl también en esta PAGINA 6 ciudad de Monterrey. 6a.- Agréguese a la lista de plantas que forman la flora de Nuevo León en su sinonimia vulgar y científica; el Algarrobo (Ce· ratonia silicua L), "Pan Gonzalitos". 7a.- Se sugiere a la Secretaría de Agricultura y Recursos Hidráulicos, auxiliar, estimular y proporcionar a quienes soliciten a la mayor brevedad posible, semillas y orientación técnica a las Instituciones Universitarias, Agropecuarias y afines, así como a los Huertos Escolares no sólo en Nuevo León, sino en la República entera aprove• chando dicha Secretaría la gentil oferta que a continuación se transcribe. Gracias a la gentileza del Dr. Walter Ritenhouse, de San Diego, California, el huerto experimental de algarrobo de Vista, se mantiene como servicio público. Allí se estudian ahora más de cincuenta variedades injertadas de árboles, la colección más grande del mundo. Estas variedades incluyen las mejores de Europa y de California. Semfüas y estacas de las mismas pueden consEguirse por medio del plan de in• tercambio de plantas, del Departamento de Agricultura de los Estados Unidos, con sólo el costo de empaquetamiento y franqueo. Sa.- Establézcanse a la mayor brevedad posible Estaciones Experimentales para el cultivo del Algarrobo (Ceratonia silicua L.), "Pan Gonzalitos", con personal idóneo en las Facultades de Agronomía y Ciencias Biológicas de la U.A.N.L. 9a.- El suscrito, Dr. Eduardo Aguirre Peoueño, ofrece, sin remuneración alguna, el • fruto de su experiencia -aunque escasa- a las instituciones mencionadas; así como a las de Química o cualquiera otra dependencia universitaria que lo solicitare. lOa.-Se sugiere a las autoridades gubernamentales, en su Dependencia de Agricultura y Recursos Hidráulicos, apoye, estimule y proporcione a las Facultades de Agronomía y Ciencias Biológicas de la U.A.N.L., una Carta Geográfica con la distribución del Algarrobo (CEratonia silicua L.), en la República Mexicana y en particular de Nuevo León así como el proporcionar material: semillas o la cooperación para obtenerla; material para injerto y aún pequeñas plantitas o arbolitos. l la.-Se sugiere a las autoridades municipales en su Dependencia de Ornato y Reforestación aprovechar el Algarrobo, árbol hermoso y siempre verde; sembrándolo en parques, jardines y avenidas de esta ciudad, ya que por sus cualidades constituye un verdadero recurso auxiliar contra la contaminación ambiental a manera de un pulmón sano, vigoroso y permanente. 12a.-Difúndanse a los huertos escolares y familiares de las instituciones educativas del medio rural y urbano, en cultivo del Algarrobo "Pan Gonzalitos". EL LABORATORlO DEL DESIERTO DEL BOLSON DE MAPIMI VIENE DE LA PAG. 3 ren muchos especialistas en zoología de buen nivel. No hace falta que vengan extranjeros a decirnos que andamos mal en muchos aspectos de la investigación básica. LA MICHILIA En la Michilía, región bajo estudio por par• te del Laboratorio del Desierto, se han realizado varias investigaciones, algunas de las cuales han servido como ponencias en los copgresos científicos mexicanos. Tales trabajos son de muy buen nivel y a ello seguirán otros más. No todos esos estudios tratan del Bolsón de Mapimí, pero en esa interesante región se pone especial atención. También se requieren estudios técnicos asequibles a los usuarios potenciales que buscan orientación. Se tiene ya una visión global realística de los problemas que afronta la ganadería en la región. De lo que se trata es de producir carne al menor costo posible y es que el manejo del agua ahí es muy costoso. Téngase presente que la capa de agua se localiza a profundidades que van de los 200 a los 300 m. No es necesario hacer malabarismos con plásticos. El suelo es casi impermeable, y sería suficiente con instalar reservorios de agua de capacidades diversas cada mil hectáreas. En el Norte del País está comprobado que se aprovecha solamente el 20% de la potencialidad productiva pecuaria de las comunidades naturales (pastizales y áreas de agostadero). De cualquier modo se impone conservar el agµa, especialmente la proveniente de las precipitaciones estacionales. El agua de perforación casi siempre es mala en toda la región. Se plantea experimentar con los zacatales de toboso (Hilarla mutica) y del zacatón alcalino (Sporobolus airoides y S. wrightii) y seguit estudiando la introducción experimental de especies arbustivas y subarbóreas para format sombras que cobijen de la intensa. insolación al ganado. DATOS CLIMATICOS Tlahualilo registra 204 mm,. de lluvia anual, en tanto que Ceballos alcanza 295 mm. anuales. Esto, señores, es DESIERTO. No hay que tenerle miedo al término. Un desierto como tal se caracteriza por lo imprevisible de las precipitaciones. Las sequías son prolongadas y a veces catastróficas. En el Bolsón de Mapimí la lluvia de invierno apenas llega al 8 % de la total anual. Del 12 al 16% de las lluvias es aprovechado por los ecosistemas, mientras que el resto se evapora. Se tienen registrados 2,700 mm. de evaporación anual, lo que da una idea del rango del DEFICIT de precipitación tan considerable en la región del Bolsón. Trascendió asimismo que es bueno conocer los usos actuales del suelo y sus recursos como requisito previo para modificarlos en beneficio del hombre. No se recomienda el desmonte total, sino el selectivo en casos que lo ameriten, previo diagnóstico ecológico del área. Conviene no cambiar la estructura original de la vegetación, sino en tal caso su composición florística; así se podrán favorecer aquellas comunidades naturales en donde existen las mejores especies con potencial forrajero, por ejemplo. Aún así no sería prudente desproteger el suelo dada la intensa erosión eólica que impera en la región del Bolsón. Testimonio mudo de esta acción erosiva del viento son los "mogotes" que dan a veces imagen escénica al paisaje desértico. En el Laboratorio del Desierto se tienen en marcha varias tesis profes_ionales y de postgrado de geógrafos como de biólogos de la UNAM. Finalmente se habló del Plan Nacional de Alimentos, de la Agroindustria, de la regulación del mercado de productos del campo (oferta y demanda) y en fin se dio una visión de conjunto en la que se advierte que el patrón de consumo está "sesgado". Hay que reconocer que en el "temporal" tenemos a los pobres de México. Urge pues la elaboración de patrones socioeconómicos acordes a las necesidades del altiplano. Al respecto se recordó que los campesinos no se guían por el factor "ganancias" sino por "la seguridad". Intervinieron en las ponencias y los debates las siguientes personas: Dr. Héctor Mayagoitia Domínguez, a la sazón Gobernador Constitucional del Estado de Durango y uno de los promotores del Laboratorio. Dr. Gonzalo Halffter, Director del Instituto de Ecología, México, D.F. Dr. Enrique Campos López, Director del Centro de Investigación en Química Aplicada de Saltillo, Coah. Dr. Carlos Vázquez Yáñez, de la Universidad Autónoma Metropolitana. Por parte de la CONAZA asistieron los ingenieros Tapia y Carlos Vergara. Sr. Armando Ochoa Solano, de la Dirección de Postgrado del I. P. N. Biól. Pedro Reyes Castillo, investigador del Laboratorio del Desierto. Sr. Cuadra quien habló sobre las bases diplomáticas suscritas por los presidentes de México y de los EE.UU. en materia científica. Dr. Richard Megank, representante de la O. E.

En general 101 métodos de planifi• cación propuestos parten de una concepción global del ejercicio de planificación: la ciencia y la tec::nología deben planearse hacia varios horizon• tes de tiempo -corto, mediano y largo pi~. Ademú los planet deben ser continuo,, coherentes, integrados, participantes y nexibles. F.I diftd.l estar en desacuerdo con estu recomendaciones, y mú dificil aún usarlas para elaborar un programa para desarrollar la ciencia y la tecnologl'a en un pa1s fil proceso de desarrollo. Loa m~os de planificación de la ciencia y tecnalogía sueleo exigir también que los planes queden incorporados dentro de un plan de desa• rrollo nacional. Sin embargo, casi todos los autores concuerdan en que son pocos los pafses donde la planificación de ciencia y tecnología puede tener tales alcances, y mucho menos aquéllos donde existen planes de desarrollo nacionales. La planificación del desarrollo apareció en la literatura como una especie de factor mágico para transfonnar rápidamente a lu sociedades atrasadas . Pronto se reconoció que la planificaciOn no podía llegar mu• cho más allá del manejo de unos cuantos inctrumentos de politica económica, usualmente utilizados para políticos de estabilizaciOn de corto plazo. En este clima intelectual, fueron creados los Consejos Nacionales de Ciencia y Tecnologla, como CONACYT en México, DifrcUmente puede un Consejo de este tipo manejar todos los ln~trumentos de politica de que ae diapone en teorfa. Tampoco es posible destacar el elemento tec,.. nolOgico en el manejo de Instrumentos dirigidos simultáneamente a fines mllltiples. Las polfticas tributaria. salarial, de gasto e inversión ptlblicu. de balanza de pa,~. de precios, etc., tienen ciertamente efecto, tmpor. tantet sobre el cambio tecnológico. Sin embargo, la teoría económica no ha logrado aclaramos el rol cuantitativo y causal del cambio tecnológl· co, de tal manera de darles pesos adecuados en lu decisiones prerupues• tariu, en función de objetivos mllltiples de poUtlca. Existen varios enfoques a la planificación de la ciencia y la tecnologfa, unos cuantitativos y otros no. Algunos de ellos caen dentro de lói del ~ l o tecnológico: el anilisla de costo/beneficio, insumo producto, prtncip101 de planificación global de una economía. Loe: métodos cuantitativos son aquello, dirigidos a medir el efecto micro o macroeconómlco Y_ relaciones econométrlcu entre los gastos en invetdgación y la producción. La validez empírica de estos procedimientos descansa en la vali• dez de la teoría subyacente, que como vimos en la sección anterior, es cuestionable. Existe además una baterfa de mftodos "no cuantitativos" motJvadol en parte por la insatisfacclón con ta teoría económica, y en parte por lo irreal de los ejercicios de planiflcacidn de alcance global. Entre estos mé!odos caen el de oft;~ y demandu (o requerimiento, y pos1bJlklades' ideado por la Organ1zation of E.conomic Cooperatlon and Development (OECD), métodos heurísticos que consisten en encontrar o detectar los cambios tecnológicos que son "cuellos de botella" o áreas problema· y ~ mModo del "árbol de relevancia" que consiste en encontrar las n~ Sidades tecnolOgicu implfcitas en los planes de desarrollo. En general estos mModos p&rten de una lista de proyectoa latentes, en la creencia de que éstos reflejan nece,jdades urgentes detectadas pot Ju instituciones que manejan diver101 upect01 de la Polftica tc0nóml· ca y sector privado, y por los institutos de invettlgación y el penonaI cJentffico y profeaional.

El Consejo Nacional de Ciencia y Tecnología. (CONACYT) se fundó a fines de 1970 como organismo encargado de apoyar el avance científico del pais Las funciones principales del Co_nsejo son coordinar y .P'?mo• ver la investigación científica y tecnológica; apoyar el fortal~•m.1ento de Is infraestructura científica y tecnológica; establecer conve~1os m!ernacionales en la materia; participar en la difusión del conocimt~nto c1e~tffico; y promover la formacil:n de recurrns humanos necesanos, técnicos, especialistas y oficios artesanos. Estas tareas h~ de llevarlas a. ra• bo a través de la recopilación de necesidades científicas y tecnol~fl•ca~ de los sect_ores productivo y educativo, de la captación de neces1da~es de investigación del sector pú.blico, la comunidad cientlfica, tecnológica y universitaria para apoyarlas en sus necesidades y demandas de expan· sión. El pr:mer ejercicio de planeación del desarrollo científico y tecnoló· 11-ico se inició en CONACYT con la elaboración del "Plan Nacional Indi• cativo de Ciencia y Tecnologla", publicado en 1976 donde se analizan las teorías corrientes del desarrollo tecnológico de los países del Tercer Mun• do y se examinan la dependenc:a y las dificultades y avances del siste• ma cientffico y tecnolcgico de México, por sectores de actividad productiva. Este plan establece lineamientos de oclaica general y políticas y objetivos sectoriales. (Continuará) INDICADOR Dr. Alfredo Piñeyro López Rector Ing. Agrónomo Orel Darlo Garcla R. Sec.

En la actualidad, se cuenta con dispersos estudios pardales y fragmentarios, tanto por lo que a la región como tal se refiere, como por lo que hace a las entidades taxonómicas que han recibido atención de diferentes especialistas. Lejos de lo que suele creerse, la flora de la península de Yucatán y sus relaciones con_ las de otras áreas de México, Centroamérica y las Antillas, todavía requieren mucha investigación. Por lo anterior, entre otras razones de las cuales muchas son de carácter etnobotánico, el Programa Flora de México del INIREB ha establecido un nuevo proyecto, Flora Yucatanense, el cual, aprovechando la experiencia obtenida durante el desarrollo del de Flora de Veracruz, pretende producir una obra comprensiva, de carácter regional, cuya importancia es obvia.

Se carece de estu- dios cuantitativos que indiquen cómo calcular la uignación de recur101 en ciencia y tecnologla en un presupuesto naclonaJ. Mucho meno, alln se sabe del efecto del cambio tecnológico sobre el sistema de precios, el empleo, o Ju demandu tducativu. Los mftodos de planeación muestran por su parte poco apoyo teórico . Conciben la planeac\ón de ciencia y te<:nologfa como un sistema totalizador donde todo ae relaciona con todo. Casi nunca se discute ni se hace explicito -tal V9Z porque no ex'.ste- el esquema teórico económl• co ni temporal en el que se basa el anilisis y se hacen las recomendacio- nes . La planeación, sin duda, requiere un horizonte de tiempo ya que es ineludib~ aclarar cuAndo un plan dará resultados . Es ingenuo responder 11: esta con referencias al "corto", "mediano" y "largo" plazo. Algunas preguntas a las que se enfrenta el "planificador" de la ciencia y la tecnologla son: ¿cómo fijar objetivos concretos de acción en ciencia y tecnologla? ¿cómo seleccionar las distintas alternativas para lograrlos? ¿qué mecanismos administrativos e institucionales se lequieren para llevar a cabo estos propósitos? ¿cómo se mide el éxito o el fracaso de estas acciones? ¿cómo se evalúan los ejercicios de planeación en ciencia y tecnologla? La parte diflcil, sin embargo, ocurre cuando se intenta dar respuesta a estas iocó&nitas c:oo la ayuda de una teoría económica de alcances limi· lados y contradictorios y una teoría de la planificación de ta ciencia y la tec• nologla ambigOa, confusa, dudosa y difusa. Ante esta situación para elaborar este programa se optó por una solu• ción pragm,uca de pocas pretensiones teóricas: preguntar a los que h8C9rt la ciencia y la tecno1ogla y a quienes la usan, lo que ellos consideran dtbcl hacerse en sus respectivos campos; asl como intentar crear un mecanismo de retroalimentación de la comunidad cientlfica y tecnológica por una parte y el Estado por la otra . El camino seguido consistió entonces en detectar mediante consultas directas la oferta cientifica y tecnológica por parte et. la comunidad cientifica y la demanda de ciencia y tecnologla por parte del sector productivo pjblico y privado. Posteriormente se procedió a una agrupación de estas recomendaciones por áreas de la ciencia y de acuerdo a los objetivos de politica econó-mica más urgentes del presente gobierno. DR.

En el pro¡;¡rama se pretende atender prioritariamente a los problemas más elementales de la ciencia y la tecnologla en México, antes de caer en proposiciones de potltica económica con el alcance de un plan global. Es-, pecificamente se da atención a: 1) detectar demandas latentes y al apoyo de investigaciones urgentes detenidas; 2) elevar la eficiencia de las instituciones de investigación; 3) incorporar criterios básicos de ciencia y tecno.logla en la política económica; 4) estimular o inducir el gasto privado en ciencia y tecnologia; 5) establecer mecanismos permanentes de conexión entre usuarios y oferentes de ciencia y tecnologia ; 6) formar los recursos humanos necesarios para et desarrollo cientlfico y tecnológico del pals. El programa no comprende los instrumentos de política que afectan el desarrollo de la ciencia y la tecnologla que no controla dirtclamente el CONACYT como son los impuestos, los subsidios, patentes, permisos de im· portación, etc. Aunque en su papel de asesor de otras Secretarlas de Esta• do el CONACYT en base al programa puede influir en estas decisiones . El programa es una descripción detallada de acciones concretas en ciencia y· tecnologla que, definitivamente, no pretende la transformación radical de la vida económica, polltica, social y cultural del país. Resumen del Proc;rama Nacional de Cttncia y Tecnolo¡ia 1978 • 1982 El Programa Nacional de Ciencia y Tecnología 1978 • 1982 se ori~• n6 por petición directa del Presidente de la República en junio de 1977, a la comunidad científica y funcionarios del CONACYT . El programa solici• tado debería dar respuesta a tres cuestiones básicas: ¿Qué investigación científica deberá realizarse en México y cuál incorporarse del exterior? ¿Qué desarrollo tecnológico deberá realizarse en México y cuál impor• tarse? ¿Cuáles serán el volumen, los niveles y las especialidades de los recursos humanos que se prepararán en el quinquenio? Al responder estas preguntas el programa deberá especificar el por qué, el quién, el cuándo, y el costo aproximado. En la elaboración del Programa Nacional de Ciencia y Tecnologia 1978 • 1982, el CONACYT tomó como punto de partida las prioridades de politica económica de la administración actual y las proyecciones del crecimiento de la economia en lo que resta del sexenio. El Programa Nacional de Ciencia y Tecnologia 1978 • 1982 se ,elaboró con la participación del sector productivo público y privado, miembros de diferentes especialidades de la comunidad cientlfica. técnicos de diversos institutos de investigación, directores de las principales instituciones de alta ensel\anza, representantes de todos los sectores de la administración pública federal y de asociaciones privadas. (Pasa a 1.a página 7) PAGINA 2 PAGINA 3 �EL PAPEL DEL BIOLOGO EN LAS INVESTIGACIONES SOBRE PESCA Y EN LA EDUCACION PESQUERA Dr. Héetor Chapa Salda/la Jefe del Departamento de Investigación y Desarrollo de la Dirección General de Ciencia y Tecnología del Mar, de la Secretaría de Educación Pública. En general, todas las pesquerias del mundo se desarrollaron antes de que sobre las mismas se hiciera cualquier tipo de investigación. En todos los casos, los estudios comienzan cuando los rendimientos de la pesca bajan por causas diversas, generalmente porque se aplica sobre el recurso un esfuerzo mayor del que puede soportar. A pesar de ello, es el mismo pescador quien conoce el recurso del que vive y quien transmite su conocimiento de generación en generación. De este modo, se habla de los países que son pesqueros por tradición, como los que se encuentran cercanos al Mar del Norte, los de la Península Ibérica Y otros más que por su carácter insular, ponen en contacto directo con el mar y sus recursos a quienes en ellos habitan. México no es excepción, pues no es sino has- PAGINA 4 ta casi mediados del presente siglo cuando los estudios dedicados al conocimiento de nuestras pesquerías, han merecido la atención de los estudio• sos y del mismo gobierno. En los estudios pesqueros participan una serie de disciplinas que se complementan, como son la Limnología, la Oceanografía, la Climatología, la Biología y diversas ramas de la ingeniería. Sin embargo, de todas las profesiones, en nuestro país han sido los biólogos quienes han aportado los conocimientos básicos de esta importante actividad, ya que la formación de recursos humanos en las otras disciplinas es más reciente por lo cual su participación es todavía muy relativa. Caso concreto, la formación de oceanólogos ha estado enfocada a la biología pesquera, debido posiblemente a la carencia de la infraestructura que la enseñanza y aplicación que la oceanologia requiere. Por lo tanto, sin equivocación, puede afirmarse que el campo de la investigación pesquera fue abierto en el país por los biólogos, en contraposición con otros campos de la biologia aplicada, que fueron abiertos por ingenieros agrónomos, forestales, químicos e inclusive por médicos. Es interesante señalar aquí que los biólogos, que en un principio se dedicaron al estudio de los recursos pesqueros, carecieron de lo más indispensable, sacando sus deducciones de la observación directa de las especies y sus relaciones con el ambiente, asi como de la interacción de recurso pescador o del pescador-recurso. A pesar de ello, quienes ahora cuentan con instalaciones moder, nas, aparatos, equipamiento y facilidades de manejo de la información por computadora, han venido a confirmar, las hipótesis de trabajo de aquéllos a pesar del empirismo de su desarrollo. Los primeros intentos de establecimiento de estaciones y laboratorio para la investigación marina, datan desde los años de existencia del Departamento Autónomo Forestal y de Caza y Pesca, durante la gestión gubernamental del Gral. Lá· zaro Cárdenas. Sin embargo, la falta de una orientación hacia la aplicación de lo que habria por estudiar, fue tal vez la razón de su efimera existen• cia. La costumbre de las civilizaciones del altiplano mexicano para incluir en su dieta productos acuáticos, se perdieron con la llegada de los españoles y con la implantación de otro tipo de costumbres; los invasores centraron su interés en los recursos minerales y en el comercio, pasando la pesca a ser una actividad prácticamente inexistente. Situación semejante se mantuvo hasta ya muy entrada la época del México independiente. Los programas de salud pública y la consecuente colonización de las zonas costeras, hicieron renacer la actividad pesquera. Sin embargo, aún ahora, es común que las familias de pescadores prefieran el consumo de las carnes rojas al pescado. Las actividades piscícolas, muy practicadas en la época pre-colonial, renacieron en el Siglo XIX con Esteban Cházari, aunque justo es recono• cer que en su mayor parte las ideas fueron tomadas de experiencias europeas, muy poco aplica• das en el país. El Departamento Autónomo Forestal y de Caza y Pesca, centró su interés en la zona lacustre tradicional de México, específicamente en la pesquería de agua dulce de los lagos de Pátzcuaro y Chapala. En Pátzcuaro se estableció la Estación Limnológica en la que se llevaron a cabo interesantes estudios limnológicos, pesqueros y taxonó• micos. Desafortunadam$1te, esta estación que! por tradición deberia conservarse y superarse, ha desaparecido como tal, dando paso al elegante centro de capacitación y entrenamiento haciendo de lado estudios serios sobre los recursos pesqueros del lago pese a que virtualmente se encuentras sobrexplotados. Las preguntas surgen: ¿Para qué capacitar en pesca si el pescado se acabó? ¿Para qué capacitar si los pescadores no cuentan con los medios de producción? La carpa, posiblemente la especie más adap• table de agua dulce, se introdujo en el país desde finales del siglo pasado, pero su importancia se redescubrió por biólogos al servicio del Banco de Crédito Ejidal, en la variedad que ahora se conoce como Carpa de Israel. Por otra parte a pesar de su importancia, las pesquerias marinas reci• bieron poca atención . Es justo reconocer que fueron los japoneses quienes descubrieron las exis• tencias de camarón en mar abierto que, hasta la actualidad, continúan siendo pescadas por la flota camaronera nacional y que, en cuanto a valor, representan la primera pesque ria nacional. Los japoneses obtuvieron del gobierno del Gral. Lázaro Cárdenas permisos especial_!!s para pesca exploratoria y comercial, y hubieron de retirarse cuando México .entró en guerra contra los países del Eje. Aunque se dice que su finalidad era otra, de- jaron no obstante útiles enseñanzas entre los pes• cadores mexicanos que se hicieron cargo de las primeras flotas camaroneras. El camarón y su pesca era conocida en México desde la pre-conquista, especialmente en el sur de Sinaloa y norte de Nayarit, zona en la que se le pesca desde entonces con el sistema de artes fijas conocido como "lapos". La cuna de la ahora floreciente industria camaronera de mar abierto se sitúa en Guaymas, Sonora, puerto en el cual se establecieron las primeras flotas importantes para la pesca al arrastre, así como las pri, meras plantas procesadoras mediante congelación del producto. La demanda, durante la guerra, de más producto, dio origen a la fundación y establecimiento de pesquerías de camarón en otros puertos del Pacifico y del Golfo de México. La importancia y valor de esta pesquería, fue campo propicio para el establecimiento de la primera institución dedi· cada al estudio de una pesqueria de alta mar, el Instituto de Pesca del Pacifico, A. C., sostenido y administrado conjuntamente por la iniciativa privada (Cámara Nacional de la Industria Pesquera como la Unión de Armadores de Guaymas), y el gobierno federal a través de la Secretaría de Marina; las sociedades cooperativas intervinieron en ésto posteriormente. Como antecedente de este Instituto se señalan los estudios del camarón llevados a cabo por biólogos pioneros en barcos de la armada nacio• nal: Mauro Cárdenas Figueroa y el autodidacta señor Antonio Garza García, asistidos y asesorados por el biólogo norteamericano Milton J. Lindner, agregado de pesca de la embajada de los Estados Unidos de América. El Instituto contó posteriormente con la colaboración del biólogo M. A. René Núñez Sánchez, quien fungió como primero y único director, el que esto escribe y el Biólogo Pedro Avila Salazar, así como un cuerpo de auxilia, res y estadigrafos. Para las investigaciones se utilizó un balandro adaptado a la pesca de arrastre bautizado originalmente como "Sharonah" y rebautizado como Antonio G. Garcia, en honor del ya mencionado que, para entonces, había fallecido. Precisamente la primera de las crisis importantes sufrida por la industria camarone~a. que ahora se repiten con cierta periodicidad, obligó a la iniciativa privada y a las sociedades cooperativas a retirar la ayuda económica al Instituto, quEI hubo de cerrar en 1952, dejando el campo de in- PAGINA 5 �vestigación abierto y al pescador sensibilizado para posteriores estudios. Nuevamente, en 1953, los intereses creados en la pesquería de camarón de mar abierto, hu, bieron de chocar con los de los pescadores de camarón en lagunas litorales, al presentarse otra crisis. Esto fue motivo para que el gobierno fede· ral, de una buena vez, se echara a cuestas el estudio del recurso, su pesquería y la búsqueda de una administración que equilibrara los intereses. Fueron biólogos los que, tras varios años de estudio, dieron cima a los conocimientos básicos de la biología de las especies de camarón, su distri• bución latitudinal y batimétrica que, todavía aho• ra, se emplean en la reglamentación de la pesquería. Fue un funcionario de gran visión y comprens,on de la importancia que para la administración de los recursos pesqueros tiene la actuación de los biólogos, quien dio el empuje definitivo: el Al• mirante Antonio Vázquez del Mercado, a cargo de la Dirección General de Pesca e Industrias Conexas como dependiente de la Secretaría de Industria y Comercio, durante parte del sexenio del Lic. Adolfo López Mateos. Hombre de amplia preparación marina, escogió como su subdirector al biólogo Rodolfo Ramírez Granados, quien había estado a cargo de la correspondiente oficina de estudios biológicos pesqueros, encabezando un numeroso grupo de jóvenes, muchos de los cuales en la actualidad detentan importantes puestos en la administración pesquera y educativa del país. Rodolfo Ramírez Granados, fue el primer biólogo mexicano que se elevó a tales alturas en la ad• ministración pública. Con gran visión, el gobierno federal asesora• do por biólogos cristalizó la Comisión Nacional Consultiva de Pesca y dio cima a las aspiraciones del grupo de investigadores mexicanos, ya que al mismo tiempo se fundó el Instituto Nacional de Investigaciones Biológico-Pesqueras, colocando en la dirección del mismo al biólogo Mauro Cárdenas Figueroa. Los biólogos diseñaron la red de esta• cienes de investigación que ahora se extienden en casi todos los litorales, así como gran número de las estaciones piscícolas. El Instituto dio a la luz el fruto de las investigaciones en numerosos trabajos de divulgación que aún hoy son buscados por los estudiosos, y formó la colección cataloga• da más importante de recursos acuáticos con que ha contado ef país, la cual desgraciadamente fue desmembrada y repartida con el cambio de administración. El cambio se tradujo también en otro nombre para la institución: Instituto Nacional de PAGINA 6 Pesca, así como p¡¡ra las estaciones de investigación pesquera y los centros de piscicultura, pasan: do estos últimos a depender de un fideicomiso pa· ra finalmente quedar bajo la tutela de la actual Dirección General de Acuacultura del Departamen· to de Pesca. Fueron biólogos del Instituto Nacional de Investigaciones Biológico-Pesqueras, quienes idearon y llevaron a la práctica las primeras obras de mejoramiento ecológico en las lagunas costeras del Pacífico, criaderos de camarón, obras que en muchos casos fueron llevadas a cabo por las sociedades cooperativas de pescadores. Fueron estos biólogos quienes estudiaron la pesquería de ablJl Ión, sardina y langosta, hasta entonces desconocidas; hicieron los primeros estudios de contaminación y sus consecuencias; descubrieron las existencias de merluza; iniciaron los estudios de las algas marinas; introdujeron al país la tilapia africana, la carpa herbívora y el paiché y pusieron 'en marcha los primeros trabajos serios de ostricultura en las lagunas del Golfo de México; estudiaron y señalaron el peligro de los azolves en las lagunas litorales del Pacífico; estudiaron la i'nvasión por malezas acuáticas en gran número de nuestros embalses. Además, fueron biólogos quienes p¡¡rticiparon en la consolidación de la Dirección General de Lagunas Litorales, dentro de la Secretaría de Recursos Hidráulicos, cuyos estudios fueron la base para la existencia de la actual Dirección General de Acuacultura. Fueron biólogos quienes diseñaron los planes de estudio para la formación de grupos interdisciplinarios en los centros educativos de provincia, los que, mediante contrato, hicieron posible que universidades hasta entonces marginadas, se echaran a cuesta estudios serios de pesquería y con• laminación: la Universidad Autónoma de Baja California, la Universidad Autónoma de Sonora; la Universidad Autónoma de Sinaloa; la Universidad Autónoma de Guadalajara; la Universidad Autónoma de Nuevo León; la Escuela Nacional de Cien, cias Biológicas del 1. P. N., y el Instituto de Biología de la U. N.A. M., así como el Instituto Tec, nológico y de Estudios Superiores de Monterrey. Muchos de los investigadores que con ello tuvieron su primer contacto con los recursos, confrontan ahora importantes responsabilidades en la administración pesquera. Es justo señalar que, a pesar de los ya largos años transcurridos, existe todavía un divorcio ent'.e la política y los lineamientos de la investigac,én, en detrimento de la buena administración de los recursos pesqueros. En muchos casos, las pesquerías en su inicio han sido favorecidos no sólo por el interés de los propios pescadores, sino por personas ajenas al medio que, acuciadas por los dividendos, hacen inversiones para retirarse cuando se presenta la primera crisis. Creemos que una vez pasada la efervesc!lncia de grandiosos planes para el desarrollo de la pesquería de México, se imponga el buen juicio de los biólogos en bien de los recursos y del pueblo que tiene justo derecho a participar de los mismos. En cuanto a la educación pesquera, los biólogos participaron en las desaparecidas escuelas prácticas de pesca, fundadas durante el gobierno del Gral. Manuel Avila Camacho. Fueron biólogos quienes establecieron el actual sistema de educación pesquera que depende de la Secretaría de Educación Pública en el cual se preparan técnicos de nivel medio superior para el desarrollo de la industria, y de nivel de licenciatura. En particular, la carrera de Ingeniero en Acuicul• tura, consta de un currículum en el cual se equi• libran las asignaturas que enmarcan los conocimientos básicos de la biotecnia dentro de la si. tuación socio-económica por la que el país atraviesa, y en la que se concibe el profesional como un conservador de los recursos quien aplica sus conocimientos como una respuesta, en parte, al perjuicio que el avance industrial del pais está experimentando. (Viene de la página 3) El programa se elaboró en dos etapas: a) consulta a la comunidad clentifica organizada en 39 Grupos de Trabajo, resumen y ordenamiento de la información; y, b) consulta a los sectores ptJbllco y privado, clasificación de proyectos y fonnulación de programas. En la primera etapa se solicitó a cada Grupo de Trabajo, la elaboración de un documento que comprendiera los siguientes aspectos: diagnóstico económico de la rama: diagnóstico de ta investigación cientlfica y tecnológica en la rama; planteamiento de los objetivos y metas 1978 • 1982; programas, subprogramas, y proyectos considerados por el grupo como prioritarios para dar solución a los problemas derivados de los diagnósticos realizados; los medios flsicos (infraestructura), rec.ursos humanos, y financieros para realizar los proyectos, y estimación de costos. Como resultado se elaboró un extenso documento con 837 proyecto.,, que, constituyeron lo que podríamos llamar la "oferta" de investigacíón. Cabe aclarar que este trabajo de recopilación realizado por los Grupos de Traba¡o cubrió aproximadamente el 90% de las instituciones de investiga• ción existentes en el pals. la segunda etapa de trabajo consistió en la recopilación de las necesidades de investigación de los sectores ptJblico, y del sector privado. Pa• ra ello se solicitó a las dependencias publicas denominadas "Cabeza de Sec• tor" y a tas asociaciones privadas nombraran representantes. Paralelamente al Programa de Investigación, se formuló al Programa de Formación de Recursos Humanos 1979 • 1982, que propone como me• ta otorgar 17,000 becas en e1 periodo seftalado, con un costo aproximado de 3,098 millones de pesos. De estas becas, 7,000, o sea el 40% , están ya comprometidas a tra-1 vés de convenios con instituciones de educación superior e investigación, o con dependencias del sector público lo que garantiza en mayor grado la in• corporación de los exbecarios al trabajo. Oe acuerdo con las áreas prioritarias del Programa Nacional de Cien• cia y Tecnologla, y en previsión de futuros programas de expansión, las be· c.:as serán distribuidas de la siguiente manera: al área de industria el 21 %; Energétic0'5 recibirá el 17%; al área Agropecuaria y Forestal se otorgará el 13% para Nutrición y Salud el 11%: Desarrollo Social tendrá el 9%: a Pes• ca se le asignara el 7%: Construcción, Transporte y Comunicaciones recibi• rá el 7% y Administración PtJbtica, que es un renglón nuevo, tendrá el 2%. Nombrados los representantes, se celebraron reunl0n8S con cada uno de ellos para sugerir procedimientos de trabajo y proporcionarles la "oferta" de investigación recibida de la comunidad científica, con la idea de qud de este conjunto de proyectos seleccionaran los que consideraban necesa• rios para satisfacer las necesidades de investigación en su área. Además se les pidtó que sugirieran nuevos proyectos para atender sus necesidades futuras. Se recomendó como procedimiento de trabajo: la consulta pirami· da\ en cada dependencia y en los organismos pertenecientes al sector, la aprobación por el titular de la dependencia de las demandas planteadas; 'I la elaboración de un documento con la informción solidtada. Como rasul• tado de esta tarea se recibieron 28 documentos oficiales que comprendie• ron 2,171 demandas o propuestas de investigación originadas en el sector público, y la selección, como prioritarios, de 318 proyectos de los plantea• dos en la primera etapa por la comunidad científica. La elaboración del programa se apoyó también en un diagnóstico ge• nt-ral del sistema cientlfico y tecnológico que permitió identificar los prin• cipales obstáculos a su desarrollo. Para ello, se consultó la opinión de la comunidad cientlfica, especialmente directores de centros e institutos de investigación. En base a estas consulta-s se lograron detectar los problemas a continuación, cuyas soluciones han quedado incorporadas al programa. Con el material proporcionado por los 39 Grupos de Trabajo, por los representantes del sector ptJbllco y el sector privado, y el diagnósti~o general del sistema cientifico y tecnológico, se formuló el Programa Nacional de Ciencia y Tecnologla 1978 • 1982. Con frecuencia se improvisan grupos sin capacidad para organizar la investigación, que además sustraen investigadores de proyectos mejor configurados y en marcha y distraen fondos para la investigación. El programa agrupa la investigación en nueve áreas prioritarias: lnves• tl¡ación Básica; Agropecuaria y Forestal; Pese.a; Nutrición Y Salud; EnerP, ticos; Industria; Construcción: Transporte y Comunicaciones.; Desarrollo ~ cial; y Administración Püblica. El Programa Nacional de Ciencia y Tecnologla se estructura con 142 programas especificas y 2,439 proyectos, con un costo de más de 6,000 millones de pesos. Tanto \os programas como los proyectos están sujetos a un proceso de actualización (dina.mico), en el cual se agregarán nuevos proyectos y conformaran otros programas en cada una de las revi-siones .11 las que se sujete el programa. 1. Coordinación de la actiYidad cientiOca. En ausencia de una pol\tica cienliflca y tecnológica bien coordmada, hasta ahora las instituciones de Investigación han operado en forma independiente y con orientaciones individuales . En estas circunstancia-s se dificulta definir campo,. de especialización, que al dividirse excesivamente ha· cen que disminuya la calidad de la producción cientifica. los '58Clores productivos, ptJblico y privado, sólo excepcionalmente acu· den a las instituciones cientlficas nacionales. Este abandono explica en par• te la correspondiente falta de interés de las instituciones de investipciórt por 10'5 problemas nacionales inmediatos y concretos. Existe escaso apoye, institucional para inventar, mejorar y desarrollar equipos y otros recursos productiYOS . Cuando alguien ha inventado o descubierto algo, carece de medios para anunciar, comercializar y buscar clientes para sus inventos. Para resolver algunos de estos problemas el programa da atención es• pedal a los procedimientos de vinculación entre el sistema nacional de Ciencia y tecnología y les sectores productivos p(lbhco y privado.

Además de los problemas de coordinación y los Am· bios soenales, otro obstáculo externo al que se enfrentan tas instituciones de investi¡ación es la incertidumbre sobre sus recursos económicos. la incertidumbre respecto al apoyo financiero a corto y mediano plazo afecta sin duda la marcha de los centros de mvesligación. Con frecuencia se reduce 11 irea de estudio y no se contrata al personal que se tenia previsto. A pe. s,r de que algunas instituciones cuentan con recursos para crecer en forma sostenida::, de que los programas de becas han hecho que aumente 19 disponibilidad de personal preparado, subsisten dificultades enormes para contratar e incorporar a un nuevo investigador. Por lo indirecto del procedimiento, a la invntipción suelen Htpr pocos recursos. El financ.amiento debe obtdectr a la capacidad dt los e.Iros para producir clenc.a y tecnología, y no a las propott:ionls dt la ffllSI estudiantil dA los centros dt enseflanza I k>s que estjn adscritos. los procedimientos presupuestales del Gobierno Federal son, con pocas exupciones, Inadecuados e inoportun0$. El presupuesto se conoce ya avanzado e1 cuando much0$ de los nuevos programas de trabaio se han suspendido por no saberse si realmente habra recursos y, lo que es _peor aún, se interrumpen estudios en marcha. ª"º• En cuanto a los problemas Internos, s.alvo contadas excepciones, los centros de in'l'l$tipdón no tienen una organiz.ac:ión administrativa .tew.. da y f1tllible. lo anterior se manlflesta en el uso ineficaz que hacen de sus fWCUl'$0S Y, lo que ts mucho mis grave, en la necesidad que tienen los di~ rtctoru de centros o de proyectos de dedicar aran par1e de su tiempo a asuntos administrativos. Una de las consecuencias mis datlinas de este pro• blema se manifiesta cuando 10$ mejores especialistas en c.ada e.ampo son designados para los puestos directivos de los centros de investipc:ión. En relación con estos problemas, la política de formación de recursos humanos del programa pone éntasis en la preparación del personal administrativo y de nivel t6cnico para apoyar la act1v1dad c1entlf1e1. Se estudian tambi6n procedimientos encaminados a asesorar y apoyar a los centroa de lnV9Stipción en sus trámites presupuesta1es con et Gobierno Ftderal. 4. El empMO de dentffko&.

No se han elaborado planes para integrar a los ellbecarios a proyectos especificos de inestigación, ni pan, situarlos en instituciones de educación superior ni tampoc:o para darles medios como laboratorios, talleres y estaclones 1,cperimentales para que se aproveche plenamente la invtrsión qu• M hizo en prepararlos. El trabajo cientltico y tecnológico de alta calidad exi¡e dedicación de- tiempo compteto, y p,ira hacer esto el invtstipdor debe percibir un, remu• ner•ci6n adecuada.

Esta dispersión constituye uno de tos impedimento5 más frecuentes para el funcionamiento de grupos de trabajo de buen nivel Los me¡ores elligen sueldos competlti'los con la Industria y otras instituciones del Gobierno. Las ¡randes universidades, los institutos de enseftanza superior y el sector público. pagan a sus especialistas sumas elevadas que los Clntr0$ de investi¡ación más pequenos no pueden pagar, lo que genera una fuga de cerebros de instituciones del sector clentifico al sector público. Junto con la polltica de descentralización de la investigación cientlfica que el CONACYT empieza a aplicar en su politlca de recursos humanos, se promovertn las mechdas para elevar las percepciones y beneficios de los investigadOf'es, para atenuar los desniveles de que ya se ha hablado. 5. lmportaci6n de Equipo, Matwiales y 5-YictoS de Mantenimiento. Numerosos proyectos de investigación se atrasan o interrumpen poi' no contar oportunamente con el equipo y los materiales indispensables. La mayor parte de 6stos, lo mismo que los costosos animales de experimentación, son importados, puesto que su producción nacional es muy limitada. El tra~jo cientlfico con frecuencia se retrasa porque no hay en el pals equipo y personal preparado para dar servicio de mantenimiento y reparación al equipo cientifico. Muchos aparatos sólo pueden ser reparados poi' especialistas de los que no se dispone, además de que en muchas ocasiones se carece de las instalaciones para proporc:ionar servicios. La falta de servicios de mantenimiento y reparación ha provocado también un aumen♦ to de las importaciones y del equipo ocioso. El CONACYT ya cuenta con la Oficina de Despachos Aduana les de la Comunidad Cientlfica. A sus funciones de obtener franquicias, dispensas, y tramitar despachos eduanales, se ª"adirá la de difundir en la comunidad cienUfica las disposiciones y facilidades para la importación de materiales y equipo. También se fortalecerán los centros que prestan servicios de instrumentación en el pals. � Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Facultad de Cienciu Biol6¡icas UANL Del 23 al 29 de marzo del presente afio se lle..-6 a cabo el XVI Congreso de la Orpnización Jn. temacional para el Estudio de las Plantas Suculen- tas con sede en tas ciudades de ~éxico, O. F. Y Tehuacán, Puebla. La inauguración oficial estuvo a cargo del Dr. José Sarukhán Kermes, director del Instituto de Biologia de la Universidad Nacional Autónoma de México. La ceremonia continuó con la entrega de la presea "Cactus d'Ot" a la M. en C. Helia Bra- vo Hollis, como reconocimiento a la mejor cientifica del mundo en el estudio de las plantas de la familia Cactaceae, la entrega fue hecha por el Sr. Marce! Kroenlein, representante de la princesa Gra· ce de Mónaco, y actual director del Jardin Exótico de Mónaco que agrupa una de las ffdls grandes colecciones de plantas suculentas. El 26 de marzo. el suscrito, en representación de la Facultad de Ciencias Biológicas de la Universidad Autónoma de Nuevo león y del Centro de ln\'est1gaciones Brológicas, presentó una conferen• cia denominada "Contribución al Conocimiento Floristico,Eco!ógico y Utilización de las Cacticeas del Municipio de Mina, Nuevo León, México, poniendo de manifiesto que existe una gran cantidad de especie~ en el área estudiada y que la gran mayorta de éstas se localizan en el Matorral Inerme Parvifolio y en el Matorral Crasirosulifo\io Espino, so debido a las condiciones ambientales que se dan en dicha área. De ~ utilización que hacen de las CacL::..~s en estii región son muy notorios los usos medtcinal, alimenticio y forrajero, es decir que PAGINA 2 satisfacen en parte las necesidades mis apremiantes de los habitantes de la localidad. El programa del Congreso contempló un simposio sobre conservación en el cual estuvieron como invitados especiales funcionarios de la SARH, de CONACVT, del Instituto de Ecología, A.C. Y del INIREB, en él se manifestó que los factores que amenazan a la flora suculenta son: el fuego, el avance de la población y la colecta inmoderada. El seflor Hemando Sánchez Mejorada, Presidente de la Sociedad Mexicana de Cactologia propone como solución para conservar las cactáceas fomentar los viveros y hacer un buen uso y manejo de éstas, ya que representan junto con el resto de la vegetación uno de los grandes patrimonios de nuestro territorio. El Dr. Werner Rauh, Director del Instituto de Boünica Sistemática y Fitogeografla de la Univer• sidad de Heidelberg, República Federal Alemana, diserta sobre la conveniencia de facilitar los permisos de colecta y exportación de plantas con fines científicos, como una posible solución o dismi• nución del escandaloso contrabando que se hace con estas plantas. El Sr. David Grigsby, cacticuttor en escala comercial en los Estados Unidos, habló de la impor• tancia de la comercialización de las plantas suculentas en la conservación, haciendo notar la gran necesidad de tener plantas accesibles para coleccionistas y científicos en cantidades considerables, dijo también que se deben suprimir los permisos de colecta de grandes cantidades y que solamente se deberian de otorgar permisos de colecta de 4 ó 5 ejemplares por especie, además, puntualizó sob~ la aplicación de las leyes de colecta y san• ción como una medida de protección de las cactá· ...,. El editor del "Cactus and Succulent Joumal" Sr. Charles Glass habló sobre la urgencia de conocer II recuperación natural de las plantas sucu· lentas en su hábitat natural, propone para esto realizar estudios tendientes a conocer la dinámica de las poblaciones y la bkltogia de las especies lle• vando a cabo esto en áreas determinadas en cooperación la 1. O. S. con los gobiernos de los pai• ses respectivos. El representante del INIREB rMnCiond que trabajen actualmente en la loellinci6n de ,,... Cttticas donde se piensan tstableclf" mervas ecotógicn, w!Yeros de prupqac:ión y corn.dalización J nombró a l.apotitlln de las Slli.-.s, f'ulbll corno un lugar irtdicado para empinar con tales establecimientos. esto con la ayuda de II parte ofi• cial (Gobierno del Estado}, parte privada (dentro del marco socioeconómico de to& ejidatlriol) y 11 parte ~ a (IHICnfflitnto 1'tnico del JNIR EB). El t9Presentante dt la SARH I ca,., del departamento de aprovechamiento de ~ no maderables hizo UI\I mefta histórica de las leyes de protección a las cacticeas, menctonlndo que el 30 de diciembre de 1933 por primera vez se decretó una ley de no exportación de plantas c:ac• ticeas, sus frutos o sus semillas. Indicó que los permisos de cofect:1 y exporta· ción .se otorgan solamente a: l . - Cientlficos extranjeros avalados por una Uni• versidad. 2.- Científicos nacionales de presti¡io reconoci<lo. 3.- Personas propuestas o autoriudls por el lns• tituto de Biología de la tlNAM, el Instituto Politécnico Nacional o .la Sociedad Mexical\l de Cactotogia. Durante el Congreso tuvimos la o,:,ortunidacl de visitar importantes zonas cactológk:as como la de la Barranca de Metztit"n, Hidalgo donde pudimos observar la flora caracterlsbca de la región, cuyos componentes principales son: lurllra ,,.. retensi,, Gochnatia hypoleuca, Mimou biuncitaa, Acacia tortuosa, Apye striat:1, Jllropha dioica. Fouquieria splendens, DasJlirion S1111c Dplqllu..;, etc., entre las especies de cactáceas, hay algunas como Cephalocereu1 sanllis "viejitos" y .._.. reu, dumorlieri, que forman verdaderos bosques debido a su densidad, la primera es una especie endémica, columnar o 11mificadl desde la bese que llega a medir hasta 15 metros de attura. Se encuentra distribuida en toda II bamnc.a en attltudes menores a 1,600 metros, creciendo sobre a• lizas. la segunda crece principalmente en terffnos bmtticos, son plantas ..candellbriformes .de 6 a u. metros de attura, provistas de un tronco corto generalmente menor de un l metro de altu· ra y con muchas ramas erectas. Tambi~n fueron observadas en las laderas rocosas cercanas a la PJl>lación de Metztitlán especies como Astn,phytum amatum, MyrtlHocactus po. metrizans, Echinocactus inl'ffllt Theloclctu5 hoffl. pilus, Ferrocactus echidne, Mamillaria magnimamma, Maminaria obccnena.

Gradual• mente se ha venido • entender que una buena parte de tales deficiencias se encuentra en la falta de integración de k,s ecólo¡os y otros cientifi• cos ambientales al proceso de la toma de decisiones, más notorio en donde e! desarrollo de la ecolo,:ia es deficiente, como sucede en los pal• ses subdesarrotlados, e incluso en algunos con tecnologías aY1nudas. Los problemas actuam son graves, tenemos d6ficit de alimentos, teenoloa:ía insuficiente, o és• ta es eficiente en causar nUIYOS problemas, como sucede con la contaminación y deterioro am• bientales crectentes, resultado del superdesarrollo industrial; tambi6n tenernos carencias económicas y falta de productividad agropecuaria, limitación por agua insuficiente de ampfias zonas del mundo, falta de espacio vital pera los individuos y fas familias, asi como habitación hogar aceptable para ellos y la sociedad; aubdesarroUo económico, particularmente en el campo, crecimiento demográfico incontenible, combinados con un deterioro social que se a¡udiza. Durante mucho ttempo en Mtxico se habló de que "¡obemar es poblar'' ahora se .menciona que "gobernar es desarrollar", otros opinan que "gobernar es tecnificar''. De la aplicación de los principios ecológicos fundamentales, la posición .en varios paises est6 cambiando a un nuevo con• cepto: Gobernar es planear la supervivencia. Los recursos naturales -son limitados, finitos; algunos sen renovables o manejables, siempre que PAGINA 4 se usen con las reglas del juego, es decir racio- nalmente, y como entes viY05 o fenómenos fun• damentlles a ck:tos de los seres vivos, racional quiere decir ecológicamente. Esto nos lleva a la definición Cile rea,rso. Sin dea:enerar en .sem6n1ica, recurso III un concepto cuhural . lo que tiene utilidad rul, o potencial, es un ftCUnO. No importa que qued& fuera de lo conocido, pues en este caso es sólo un problema dt ilJf'M)rllncia, no de falta de utilidad. LI naturaleza, puesto que de ella, en ella y por ella vivimos, es un recurso real, tangible, limitado, y tam~ delicado, a veces en exceso, que debemos aprender a usar con inteligencia. Hasta la fecha, en muchos peises el uao de )os recursos naturales ha $ido de tipo nof'Mdko, incluso cuando se forma parte de complejos altamente civilizados: explotar hasta acabar y bu$car otro recurso. Este tipo de explotación ya no puede seauir, pues es atentatorio a las riquezas naturales, que son la economla de nuestro presente y nue-stro futuro. Sin embargo, ~ra ltepr a la correcta expJotlci6n de los mismos, -es necesario cambiar 11 mentalidad. De la bUsqueda simple de .una pnancil económica, necesitamos pasar a la arn,onia con ti resto de la natunlle.za, en el cual sea posible encontrar una salud razonable y un nivel de vida digno. Para alcanzar tal situación, debemos aplicar el concepto de Ecotocia '/ caracterizar el .ecosist• ma de la humanad, e incoq,orar y pesar t.

Los Jardines Botánicos son instituciones organizadas para el mantenimiento de colecciones de plantas, usualmente representativas de una gran cantidad de Familias Botánicas, con fines de conservación, reforestación, científicos, educacionales y recreativos. Este consta de una área de exposi• ción de plantas de zonas áridas, un Arbcretum, un vivero, una área de reserva natural y un estanque de exhibición de plantas acuáticas. ¿Qué necesidad existe en establecer un Jardín Bo• tánico en nuestra región?

RESUMEN: Debido al papel primordial que juega la vegetación en el desarrollo de la vida y en la conservación del suelo y el agua y a los grandes disturbios que la actividad humana provoca a las comunidades vegetales, se presenta el siguiente proyecto para el establecimiento de un Jardin Bot¡\. nico regional, el cual consistirá de áreas de investigación y exhibición de plantas regionales, una área de propagación de material vegetal para reforestación, un reservorio natural, un lugar don, de se pueda mantener las especies vegetales que se encuentran en peligro d~ extinción y jardines de adaptación y propagación de algunas especies de importancia como recurso natural. men los animales y que posteriormente transforman a proteína animal, misma que es consumida por el hombre. Otro resultante de la actividad fotosintética es la formación del oxígeno, elemento fundamental en el proceso respiratorio de los se• res vivos . Considerando lo anterior, y estando conscien• tes de que el rápido crecimiento de la población humana y sus necesidades apremiantes de nuevas vías de comunicación, nuevos asentamientos humanos, la utilización de nuevas áreas en actividades agropecuarias y forestales, la construcción de grandes depósitos de agua, etc., actividades todas que traen como consecuencia un gran disturbio y destrucción de la vegetación nativa, así como también han sido éstas las causas determi• nantes de la desaparición de numerosas especies y de que muchas otras estén ahora en peligro de extinción, se hace por lo tanto necesario la existencia de un Jardín Botánico en nuestra región que logre despertar el interés y crear conciencia sobre lo relevante del conocimiento del mundo biológico que nos rodea, al que es preciso que prole• james.

PAGINA 3 �EL PAPEL DE LA BOTANICA EN EL DESARROLLO DE MEXICO Dr. Arturo Gcwez Pompa.• Director del Instituto de Investigaciones sobre Recu~ Blótlcos, A. C. Jalapa, Veracruz. Múleo. CONFERENCIA PRESENTADA EN LA CLAUSURA DEL VII CONGRESO MEXICANO DE BOTANICA EN LA CIUDAD DE MEXICO, D. F. Existe una conciencia muy clara en la gran mayoría de los investigadores botánicos de nues• tro país sobre la importancia que juega la ciencia de las plantas en el desarrollo de México. Por otro lado, es justo mencionar que la botánica mexicana ha valorado, en líneas generales, su papel y su compromiso ante el país . Fruto de ésto ha sido la prioridad que se ha venido dando a través de los años hacia disciplinas que están íntima mente ligadas al desarrollo del país, no creo que ésto haya sido fruto del azar, sino una actividad inconcientemente orientada hacia las prioridades nacionales. A través de los congresos de botánica podemos ir viendo con toda claridad la evolución de investigaciones de los botánicos mexicanos . Hemos visto por ejemplo cómo ha evoluc ionado la ecología vegetal, desde sus fases más elementales de gran complejidad y en este congreso hemos te• nido la oportunidad de escuchar nuevos avances, obviamente la investigación ecológica de los botánicos mexicanos ha contribuido con información y a marcar rutas a programas importantes de de• sarrollo nacional, como son las investigaciones para determinar los coeficientes de agostadero, la determinación de la importan~ia cartográfica de los factores ambientales que sin duda ayudaron a la creación de la Comisión de Estudios del Territorio Nacional, (ahora DETENAL), investigaciones sobre recursos vegetales económicamente importantes para el país, como pueden ser los estudios de barbasco, de la palma china y de otros productos más. La llamaela de atención para .a preservación de algunas zonas biológicamente importantes y en peligro de desaparición, ha provenido en gran parte de botánicos mexicanos, aun cuando esta actividad no haya tenido la respuesta que quisiéramos haber tenido por parte del Estado. La ecología vegetal mexicana ha sido una ciencia comprometida con su país y ha logrado PAGINA 4 aportar contribuciones no sólo de interés para México, sino también para otros países. Esto es el aporte de esta disciplina a la ciencia universal. Si la ecología tuvo una alta prioridad y ésta coincidió con algunas necesidades del pals, es im• portante también destacar el creciente Interés que los botánicos mexicanos han venido manifestando por el campo de la botánica económica, etnobotánica o lo que en un término más global se encierra dentro de la llamada ecología humana. Al igual que en el caso anterior, el desarrollo de esta rama de la botánica ha venido creciendo rápidamente en los últimos años, y nuevamente refleja el compromiso que sienten los botánicos mexicanos con el país . El desenvolvimiento de esta rama aplicada de la botánica, surge como una ne, cesidad de rescatar los conocimientos empíricos del pueblo de México acerca de la naturaleza. La etnobotánica mexicana está fuertemente enraizada a su pasado, la indagación sobre los usos de las plantas, de los sistemas de cultivos, los indicadores empíricos ecológicos, la percepción del medio ambiente por las culturas indígenas, dan el marco conceptual a esta área de la investigación cientí· fica mexicana. Los aportes ya son trascendentales para el país y también tienen su valor para la ciencia universal . Esta tendencia de investigación también considero que no nace de la casualidad, sino que es fruto de la preocupación de algunos botánicos por hacer una ciencia más comprometida con su pueblo. Es también importante des, tacar que una buena parte del impulso que hemos observado en este campo, proviene del empuje y entusiasmo de los estudiantes de biología y agronomía que han exigido a sus profesores e instituciones, una educación más ligada a la realidad nacional. El afán de buscar los conocimientos y los problemas de nuestras comunidades campesinas marginadas ha empujado a botánicos mexicanos a trabajar en distintas zonas del país tratan- do de recabar, ordenar y difundir la Información recopilada. Fruto de esta actividad la hemos visto también en este congreso y quizá en varios congresos futuros, pero la semilla viene germinando desde hace ya algunos años y también consi-· dero que acertadamente la comunidad botánica de México ha identificado una vez más otra prioridad nacional. Es indiscutible el hecho de que el avance de la ciencia de las plantas en México difícilmente puede entenderse si no contamos con inventarios de la flora del país. Aquí también es necesario indicar que congreso tras congreso se ha venido insistiendo sobre la necesidad de intensificar, favorecer e impulsar los trabajos tendientes a integrar el conocimiento de la flora de México. En este campo podemos mostrar los resultados optimistas que todos quisiéramos oir; las razones son muchas y también se han repelido hasta la saciedad: la falta de taxónomos y la falta de apoyo económico. Sin embargo, a pesar de las limitaciones, hemos visto crecer rápidamente en los últimos años el herbario de la U . N.A . M . , y especialmente el del 1. P. N . , asi como otros herbarios de. la República . Hemos visto aparecer nuevos herbarios con grandes posibilidades . Este crecimiento sólo se puede entender a través del aumento de las colecciones de ejemplares de herbario. Esto significa que los botánicos mexicanos nuevamente han valorado la importancia de esta actividad y en varias partes del país se han lanzado al campo a colectar ejemplares que serán la base de la futura flora de México. En este congreso también hemos visto los resultados de las actividades de los inventarios floristicos que instituciones mexicanas están realizando en el país. Considero necesario mencionar que en este contexto se puede entender la creación de nuevos centros de investigación dedicados fundamentalmente al estudio de los recursos bióticos de México. ¡Supongo que ya saben a que institución me estoy refiriendo! el INIREB. Hasta· ahora mi presentación puede interpretarse sólo como una apología a la actividad de los botánicos mexicanos, pero lo que he querido es dejar constancia de un hecho que quizás es demasiado obvio y por obvio no lo decimos, y es que las grandes prioridades nacionales en el campo de la botánica ha sido identificadas, quizá no todos los recursos que se quisieran por los botá• nicos mexicanos, la ecología regional del país, la investigación sobre la relación entre hombre, plantas y la investigación florística. Estas tres prioridades han ocupado la atención de científicos mexicanos en el pasado y seguramente la seguirán ocupando en un futuro cercano. Es necesario repetir también que ésto que ha venido sucediendo, no se ha dado por accidente. Obedece el desarrollo de la botánica mexicana, a un desarrollo también de la ciencia mexicana y ésta a su vez está ligada al desarrollo del país. La presencia de organizaciones recientes bien conocidas por todos, como CONACYT, COTECOCA, DETENAL, e INIREB y el creciente aumento de recursos humanos y económicos en los centros de investigación científica botánica en el Distrito Federal y en provincia son factores todos que deben tomarse en cuenta para entender el desarrollo de la botánica mexicana. Vuelvo nuevamente a insistir, ésto no significa que estemos en las condiciones óptimas, ni significa que hayamos resuelto los problemas fundamentales del país en el campo del conocimiento de las plantas, ni tampoco significa que no queden una infinidad de áreas grandes importantes por apoyarse, su único significado es que dentro del contexto general del desarrollo del país, la botánica ha jugado un buen papel, dadas las limitacio- nes. El mundo de problemas por investigar es enorme, como enormes son los problemas del país; PAGINA 5 �sin embargo, vale la pena hacer un esfuerzo m~s ordenado para tratar de entender lo que el paIs demanda o demandará en un futuro próximo por parte de los botánicos. Pienso q~e si bien en el pasado hemos acertado el camino al encontrar que debería tener el país, quizá no seamos tan afortunados en el futuro y sea necesario hacer un esfuerzo como grupo, como una coumnidad cien• tífica, para identificar y dirigir mejor nuestras. actividades en la investigación y tratar de que esto que nosotros produzcamos, se use para beneficio del país. Es importante reconocer que la Flora de Mé· xico no sólo interesa a los botánicos de México, son muchos los centros de investigación e investigadores interesados en la flora de México. Creo que es necesario aprovechar este interés para el bien de México y somos los botánicos de México los únicos realmente conocedores de ésto, qué es lo que necesitamos y qué es lo que no necesitamos. Tenemos que identificar en qué áreas es necesario contar con especialistas mexicanos; qué problemas inmediatos tiene el país que requieren investigación botánica y asi orientar parte del trabajo a temas que interesen al país. Debemos tratar de prever el futuro y tratar de planear nuestros esfuerzos en la formación de nuevos recursos humanos. Si nuestros recursos económicos fueran ilimitados quizá saldría sobrando un análisis de esa naturaleza, ya que en una forma u otra ten• dríamos científicos trabajando en todos los fren• tes de la, ciencia; sin embargo, nuestros recurso_s obviamente son y serán limitados y por tal moti• vo es necesario buscar las prioridades para optI· mizar su uso. Si países económicamente poderosos marcan sus prioridades en la investigación, más aún se justifica que países como el nuestro, desarrollen este ejercicio. Creo yo que la Sociedad Botánica de México, debería participar en este esfuerzo que ya se inició en el país y debería producir sugerencia para un plan nacional _de desa• rrollo de la investigación botánica de Mex1co. Creo yo que el no tener un plan, por general que este sea, que vislumbre el futuro del _país, ha impedido que nuestros trabajos sean debidamente utilizados y valorados en México . Hemos s~gu1do, sin tener plena conciencia de ello, el patron que sigue la investigación científica, t~cnológ1ca Y de desarrollo experimental de los paIses avanzados. En ellos, como es bien conocido por todos, la investigación científica se realiza en los centros _de investigación o en las universidades, los trabaJos se publican, se dan conferencias y existen los me• canismos gubernamentales o privados para u_t1l1·· zar la información producida por los trabaJos cien· tíficos con fines productivos. Es conocido el hecho de que grandes compañías están contirn.iam~~te revisando las publicaciones sobre plantas ubles; estudios fitoquímicos, estudios farmacológicos, con la idea de eventualmente poder encontrar nuevos productos, nuevas medicinas para el hombre, nuevas plaguicidas, nuevas materias primas; ésto sucede en el campo farmacéutico, agrícola, alimenticio el campo de la exploración de recursos renov;bles, etc . Si vemos a nuestro país Y observa• mos lo que está sucediendo, nos darem~s cuenta que seguimos los mismos pasos de la investigación científica de países avanzados, se publican los resultados en revistas cientlficas, se dan conferencias, etc.; pero la diferencia está en que en nuestro país no existen los mecanismos de utiliza• ción de la información producida para fines de tipo productivo de interés nacional. En ~I f~~do, la escasa producción científica de los c1enttf1cos nacionales o extranjeros trabajando sobre la botá· nica mexicana, pasa a formar parte del acervo científico internacional, con lo cual se cumple ~no de los objetivos de la ciencia, sin embargo, s1 lo analizamos críticamente, lo que está sucediendo e~ una especie de fuga de información para benef1• cio de aquellos países o instituciones que t1e~e la capacidad de usarla. No quiero que se '."alin• terprete este punto de vista y se vaya a decir que quiero promover que no se publiquen los t~baJ~s mexicanos, que no se den a conocer la c'.e~c1~ internacional, no, no es esa mi intencIon, m1 unico interés es señalar lo que a mi parecer es una falla garrafal del sistema productivo nacional: y es el de no tener sistemas eficientes de comuni~ación entre los científicos y los usuarios d? la investigación para fines productivos en México_. E~ inconcebible que los descubrimientos de cientificos nacionales y extranjeros sobre plantas de México, puedan primero ser conocidos, evaluado~ Y utilizados en otros países antes que en México. Muchos de ellos han sido la base de pr~yectos Productivos de gran importancia con gran impac· · to económico del cual México poco se ha benef1ciado Es claro que esto es un síntoma del s~b• desar;ollo del país, de la desorganización crónic~ de nu estras instituciones, de la falta de contmu'.. · • y engre1d d de los programas. La improvIsac1on a miento de funcionarios favorece nues t ra dependencia y subdesarrollo. Se requiere una estrategia Y un _plan para e1 ª. estudio, aprovechamiento Y conservación d_e ~os : cursos vegetales del país . Esto debe salir e dos los sectores interesados, no debemos esperar a que la iniciativa venga de arriba, no va a venir • · · t·iva, señalar los erro· Es necesario tomar la inicia res, sugerir soluciones y ensayarlas. Parte de nuestro subdesarrollo es precisamente eso: quedamos en lamentaciones y críticas al sistema sin haber tratado de hacer lo que sabemos y Podemos hacer. Cada investigador que no investiga, cada maestro que enseña mal, cada institución que no cumple sus objetivos son ce-responsables de nuestro subdesarrollo. Afortunadamente la botánica en México saldría bien librada de un análisis crítico. Sin embargo, deseo insistir en la necesidad de identificar prioridades, marcarnos metas, hacer un plan y hacerlo saber a quienes deben tomar las decisiones para poseer los recur• sos. En relación a la enseñanza, creo que es ne• cesario tener un cuerpo de maestros sólidamente formado en todo el espectro de las ciencias botánicas. Difícilmente podemos menospreciar un 6rea si desconocemos su campo de acción, difi· cilmente Podemos formar nuevos profesionistas a · los que hemos formado con conocimientos polarizados. Una estrategia adechada es aquélla que nos permita siempre tener opciones abiertas ante un futuro incierto. No se deben cancelar especialidades o campos de investigación que hoy desconocemos su papel para el desarrollo del futuro. La historia nos ha enseñado que lo que hoy puede ser intrascendente en la ciencia, mañana puede ser trascendental. Todo ésto nos lleva a indicar que en el futu• ro, las prioridades en la investigación botánica tendrán que ser responsablemente asignadas dándoles un valor prioritario a aquéllas actividades de la investigación científica que tenga un papel ob• vio en el futuro desarrollo del país y también científica botánica que sin tener una aplicación obvia, tengan un papel que cumplir en la enseñanza y especialmente en la estrategia de mantener opciones abiertas de recursos humanos calificados para un incierto futuro. Lo que es muy claro y creo yo que vale la pena repetirlo hasta la saciedad, aunque resulte obvio, es que la vida humana depende y depende• rá de las plantas y el bienestar de la humanidad futura tendrá que estar fincado en un cuerpo de conocimiento sólido sobre el mundo vegetal de nuestro planeta . En el caso especifico de México, gran parte del problema es muy complejo, in• tervienen factores económicos, políticos y de or• ganización; sin embargo, a pesar de lo complejo del problema es necesario estar conscientes de él. Lo que se debe hacer es tratar de vincular al sector productivo mexicano con la información de los centros de investigación botánica . Esto impli• ca una serie de acciones directas entre investiga- dores y campesinos y entre investigadores y empresarios. Para lograr ésto, habrá necesidad de romper algunos esquemas establecidos en la enseñanza superior y también revisar a fondo los objetivos de nuestros centros de investigación científica en México. Tratar de ligar la ciencia básica, la ciencia orientada, la ciencia aplicada, la tecnología y el desarrollo experimental con los sectores productivos. Es necesario que el estudiante conozca la teoría y que ésta se enmarque dentro de la prác• tica relacionada a problemas de producción del país. Se debe dar preferencia a los problemas de los grupos marginados del país, pero no con actitudes folkloristas, paternalistas y conformistas, sino con un criterio cientlfico que involucre diversos niveles de conocimiento. Se deben estudiar los sistemas indígenas del manejo de mal s, A- t.°p-• mo también se deben emprender inve · ciones · ') para la búsqueda de nuevos herbicid ; se debe .\~ tratar de entender el conocimiento qye las comu,.... nidades rurales tienen de la diversidad biológica , en su medio ambiente, como también se deben !: ~ tratar de conocer los procesos de control bioj~ co de plagas; se deben conocer los sist~t li colas tradicionales y también se deben con,u,;,,._.....,__. procesos de transferencia de genes de una célula vegetal a otra . El romanticismo científico puede ocasionar daños al igual que el desarrollismo. Debemos abarcar distintos niveles y áreas del conocimiento necesarios para el desarrollo del país. Para ello debemos conocer los programas gubernamentales de desarrollo del país que ten• gan impacto en los recursos vegetales de México para poder hacer incidir la investigación sobre ellos o criticarlos si son defectuosos. Debemos tratar de entender las deficiencias, ya que los conocimientos necesarios para su buen desarrollo deberá estar en manos de los botánicos . Las investí• gaciones de la Flora de México, tendrán que rea• !izarse cada vez en mayor escala por científicos mexicanos viviendo en México. No hay escapato• ria, la responsabilidad es nuestra y nos toca a nosotros hacer conciencia ante el pueblo de México de la importancia de nuestra actividad y trans• mitir el hecho de que en las plantas tenemos el único recurso natural renovable, que bien manejado puede ser la base de la autosuficiencia de nuestra generación y las venideras y que si lo manejamos mal, como ha sido hasta la fecha, será la causa de una dependencia cada vez más mayor del exterior.

Sólo existió en el manantial la Media Luna Comentario sobre la "Demanda" y la "Fitnción Social" de la Carrera de Biólogo En fechas próximo-pasadas el Departamento de Planeación Universitaria dio a conocer en unos estudios, que el BIOLOGO, entre otras profesiones es una de las mal remuneradas en lo económico y que contaba con menos "demanda", según lo in· dícan sus estudios de mercadotecnia. Sin poner en duda la veracidad de tal información, la idea es que al "interpretar" esos datos es donde surgen diferentes puntos de vista, ya que habrá per• sonas que puedan entender que sobran biólogos, criterio por demás plenamente equivocado, según se desprende del siguiente análisis: En primer lugar el Biólogo, tiene su responsabilidád en el estudio y solución de múltiples problemas de orden SOCIAL, ya que no trata con un "cliente" o un "paciente" que le paga sus servicios. Es el Estado Mexicano el gran empleador --0 patrón- quien establece la magnitud de la "demanda", en la misma en que debe atacar problemas del país tales como: y sus arroyos, S. L. P. a). b). Del 5 al 8 de noviembre del año en curso, se llevó a cabo en la Facultad de Ciencias Biológicas, la Doceava Reunión Anual del Dessert Fishes Coun• cil (Consejo de Peces del Desierto) . Este grupo reunió biólogos y conservacionistas de los sectores público y universitario, principalmente de los Estados Unidos, pero con participación de canadienses y mexicanos, en número de 70. El principal interés del grupo está en el uso y supervivencia de los peces de zonas áridas y semiáridas de Norteamérica (Canadá, Estados Unidos y México), cuyas especies están representadas por marcado endemismo, cuya pérdida significaría un daño cultural irreparable, así como un daño irreversible a los ecosistemas natural y humano. Los días 5 y 6, fueron dedicados a sesiones técnicas bilingües, sobre aspectos biológico, social, económico, de los peces del desierto. El dia 7 se efectuó una visita técnica a Cuatro Ciénegas, PAGINA 2 centro de abundantes endemismos en peces y otra biota acuática y semiacuática, cuya importancia trasciende las fronteras de Coahuila y México. la Escuela de Graduados en Biología presentóun análisis del presente, pasado y futuro de las actividades docentes y de investigación en peces, realizadas por el Laboratorio de Ictiología y Pes• querías. los estudiantes tesistas del mencionado la• boratorio presentaron un resumen de sus tesis y proyectos. El Departamento de Pesca informará de las labores de conservación y desarrollo que se realizan a nivel federal y en los Estados de Coa• huila y Nuevo León. El coordinador de la reunión lo fue el Dr. Sal• vador Contreras Balderas, Jefe de la Escuela de Graduados y del Laboratorio de Ictiología y Pesquerías. c). d). e). f). El hambre y la desnutrición tan característica y más avanzada cada vez en la gran mayoría del pueblo mexicano. Extender la enseñanza técnica agropecuaria a todos los confines rurales del país, donde se finca la producción agropecuaria. El aprovechamiento de los recursos del MAR, en sus más variadas modalidades. El aprovechamiento de los recursos naturales renovables, tanto forestales, como del desier• to, en general de sacar la máxima eficiencia de los recursos de cada región del país, pero siempre en función de una distribución de la riqueza que colme los anhelos de la gran comunidad mexicana, antes que los intereses de unos cuantos privilegiados, como acontece ahora. Realizar una lucha eficiente para prevenir la contaminación de la atmósfera, del suelo, del agua. Evitar el consumismo y tener un ambiente sano en donde vivir. Acabar con tantos prejuicios ancestrales y hacer del mexicano un individuo más sano, equilibrado, educado que tenga plena conciencia del momento histórico que vive y que pueda encarar el futuro con responsabilidad de lo que le corresponde hacer, y qu'e tenga bien fundamentado el entusiasmo para ese futuro, g). Que le asista un régimen con una Justicia So• cial bien establecida y definida, misma que ahorita hace falta, razón por la que fracasan y seguirán fracasando) las campañas para ha• cer que la familia sea de un pequeño número de componentes, mientras él o los padres y madres de familia, le preocupe quien los man• tendrá, de quien dependerán cuando sean vie• jos y no puedan trabajar. h). Que se haga extensivo al campo mexicano y a todas las zonas marginadas un nivel de salud muchas veces mejor que el actual, donde la mortalidad infantil sigue muy elevada, agravadas con problemas de índole parasitológico tanto que justifica que echen en corrida, a quienes van con las "campañitas" de que la familia pequeña vive mejor, tal como ha ocu• rrido en múltiples ejidos de Dr. Arroyo y de Mier y Noriega, N. L. El comentario presente va dirigido a contrarrestar la posible "afirmación" de que la profesión de Biólogo está "saturada", ya que es a esta profesión a la cual el estado mexicano debe apoyar generosamente para la formación y mejoramiento profesional, en vías de tener muchos más y mejores biólogos, al servicio del país que los requiere en tantos y tantos aspectos de la educación, de la investigación técnica y científica, donde se requie• re una mística de trabajo al servicio de la sociedad, sin el afán de lucro de que están imbuidos tantos profesionales de otras áreas. En una palabra es el Estado Mexicano, al planear su crecimiento económico y político, el que crea y regula la demanda de BIOLOGOS, por lo que todos los estudios de MERCADOTECNIA al estilo de los que realiza Planeación Universitaria equivaldrán a pegarle al mago con bolita de cris'. tal, ayuno de la realida·d social en que vivimos y de las posibles soluciones que se requieren.

Los objetivos que motivaron esta reunión fue• ron los siguientes: A.- Reunir, de una manera informal, a las personas interesadas en el estudio, conservación y aprovechamiento racional de las aves silvestres de México: a) A un grupo electo de investigadores que trabajan en el área de la ornitología a fin de que señalen, de una manera general, los posibles caminos para una efectiva protección y aprovehamiento adecuado de las aves silvestres del país. b) A un grupo representativo de conserva, cionistas, ecologistas, ambientalistas y amantes de la naturaleza y de las aves en general, a efecto de que convivan con los profesionistas de la ornitología, enriquezcan sus conocimientos sobre la materia y discutan con ellos los caminos a seguir para lograr la conservación y mejor utilización de las aves. c) A algunos representantes de las dependencias gubernamentales encargadas de la protección, estudio y fomento y aprovechamiento racional del recurso, así como administradores de fauna silvestre: criadores y domesticadores de nuevas especies; captores de aves; comerciantes establecidos en el ramo y otros. B.- Recabar información sobre personas no asistentes o sectores no representados en el evento, pero asimismo interesados en las aves silvestres del país. Biól. M. C. Armando J. Contreras B. Escuela de Graduados, FCB, UANL. C.- Elaborar un Directorio Ornitológico de México o bien completar o enriquecer los que ya existan. D.- Visualizar el panorama ornitológico nacional: a) Programas de formación de recursos humanos. b) Programas de investigación. c) Programas de conservación y /o divulgación. d) Perspectivas. E.- Analizar de una manera general la situación · de las aves silvestres del país y apuntar las primeras acciones que deberán tomarse para promover su estudio, conservación y apro• vechamiento racional. En esta reunión se agruparon alrededor de 1-00 personas entre profesionistas y admiradores de las aves. Entre los trabajos que se presentaron están: el del M.C. Rafael Martín del Campo que versó sobre los Antecedentes de la Ornitología en México, el Dr. Allan R. Phillips habló sobre el Panorama General de la Ornitología en México, como de los más sobresalientes, además, de los trabajos ornitológicos que se desarrollan en las Universidades e Instituciones del País, en estos sobresalen los de la UNAM que presentó el Dr. Bernardo Villa-Ramírez, los del INIREB por el Dr. Mario Ramos, el Instituto de Biología expuesto por el Biól. Jorge tfoccdal, los trabajos que se efectúan en la UANL por el autor, y los de la Universidad de Míchoacán los mencionó el Biól. Francisco Méndez, que son las únicas instituciones donde actualmente se tienen programas ornitológicos, además de los de la Dirección General de Fauna Silvestre. Se efectuaron mesas redondas sobre Colecciones, Educación y Conservación y la principal sobre Investigación y Formación de Recursos Humanos, en lo particular participamos en las mesas de Educación e Investigación y Formación de Recursos Humanos. En la mesa de Educación se mencionó la par• ticipación de la FCB, en este aspecto citamos el primer curso de .Zoología objetiva para niños que se impartió en el Aquarium Municipal en 1968 y las Exposiciones sobre Fauna en general llevadas a cabo en la Expo-N. L. los años 1975, 1976 y 1977, en Investigación se citaron los trabajos realizados a la fecha por tesistas y los que actualmente se elaboran y por último en Formación de Recursos Humanos, los cursos que sirven de apoyo a esta disciplina y que lo forman: Ornitología Taxonómica (optativa) en pregrado y en la Maestría en Ciencias Biológicas los cursos de Ornitología y Ecología de Aves. Dentro de las conclusiones estuvieron las de: 1.- Promover áreas de reserva. 2.- Apoyar proyectos de investigación. 3.- Impulsar la formación de recursos humanos. 4.- Detener la destrucción en varias regiones del Estado de Chiapas (como El Triunfo, en la Sierra Lacandona), Para lo cual se envió una carta ai Presidente Ljc. José López Portillo. Por último se promoverán e impulsarán más reuniones de este tipo a fin de tener una mejor comunicación entre Ornitólogos y Protectores de Aves a fin de preservar este recurso que sin duda alguna es de los más bellos de la naturaleza. Aspectos de los Crotalidos en el Estado de Nuevo León por José Luis Vallejo La familia Crotalidae abarca una gran cantidad de serpientes venenosas, en las que se incluyen: víboras de cascavel, mocasines, nauyacas, cantiles, etc., y se caracterizan por presentar una fosa sensorial localizada entre la nostrila y el ojo, cuya función es detectar las presas por medio de células termosensibles a el calor del cuerpo. El apa- rato venenoso está muy desarrollado, presenta un par de colmillos en el maxilar superior, uno a cada lado y se encuentran articulados en la parte anterior. Por su forma de retraer los colmillos hacia atrás se le llaman solenoglifas, siendo ésta otra característica de la familia. Crotalus scutulatus En el Estado se encuentran 3 géneros y 8 especies que son: Agkistrodon bilineatus única es-· pecie de este género reportada para el Sureste del Estado y se caracteriza por no tener cascabel en la cola, as. como presentar dos líneas claras sobre la cabeza, sus hábitos son acuáticos de actividad diurna y nocturna. PAGINA 7 PAGINA 6 �Agkistrodon bilineatus. El género Crotalus se caracteriza por presentar un cascabel en la base de la cola y está representado por 6 especies en el Estado: C. atrox especie agresiva y abundante, se reporta para todo el Estado; C. durissus especie de aproximadamente 2 metros de longitud y con distribución en el Centro y SSE; C. molossus y C. scutulatus especies de tamaño medio (1.20 metros aprox.) se localizan hacia el Centro y Oeste . C. 1epidus y C. pricei son especies pequeñas (aprox. 50 mts.) que habitan en montañas, la primera con distribución para todo el Estado y la segunda para · et Centro y Sur. Los crotálidos son de importancia económica debido a que se alimentan de roedores en general (ratas, ratones, conejos, etc.), manteniendo de esta manera el equilibrio dentro del ecosistema . Su importancia en la salud pública radica en el número de accidentes que causan anualmente por mordedura (inyección de veneno). Las especies que ocasionan más accidentes con frecuencia en el Estado son: C. molossus, C. scutulatus y C. atrox siendo esta última la más frecuente por su amplia tribución. El veneno al ser introducido en los tejidos subcutáneos o musculares provoca un ascenso de Ph y de temperatura en la parte afectada, está constituido por enzimas proteolíticas potentisimas que causan destrucción total de los tejidos y de los vasos, rápidamente hay extravasación sanguínea; el líquido tisular se difunde en toda el área y aumenta la presión tisular, esto obstruye el flujo sanguíneo en el área y causa isquemia (falta de oxígeno en los tejidos). La combinación de la ac•· ción del veneno y la isquemia producen destrucción difusa de los tejidos en los compartimientos musculares y en el espacio subcutáneo en la región de la mordedura. El resultado final consiste en la necrosis de la piel, tejido subcutáneo, los músculos y los tendones, en caso de ser afectada una extremidad se puede pres'entar invalidez permanente o pérdida de la extremidad. En ocasiones la mordedura de una víbira puede no inocular veneno a la víctima, esto ocurre más o menos en el 30% de los casos, en el 70% restante, el veneno inyectado varía en cantidad, desde una dosis mínima hasta una letal. La ausencia de veneno o el envenenamiento mínimo en muchos casos, explica las curaciones milagrosas obtenidas de kerosene, telaranas y grasa de pollo.

Aunque se trata de un organismo relativamente joven -nació el 27 de julio de 1977-, su prestigio está bien cimentado gracias al interés de las autoridades universitarias y a la pasión que imprimió en su manejo y los proyectos acometidos, por el Biólogo M. C. Glafiro Alanís quien ha dejado la dirección de nuestro Centro de Investiga, ciones Biológicas. Y es mayor el mérito cuando el señor Rector de la UANL, doctor Alfredo Piñeyro se fijó indudablemente en la capacidad del Biólogo Alanís para designarlo Coordinador del Proyecto de Silvicultura, que es uno de los programas más ambiciosos de las autoridades universitarias actuales y que se calcula esté listo en el curso de un ano. Pero si bien el Biólogo Glafiro Alanís ha dejado una huella imborrable, se debe también al equipo de trabajo que siempre le rodeó y que, por consiguiente al continuar ellos bajo una nueva administración, el prestigio seguirá acrecentándose. Con mayor razón si al frente del CIB se ha colocado a otro profesionista arraigado en la investigación y con un prestigio ganado en el ámbito universitario. , . CA UANL NUMERO 8 ( " El hecho de q~e el Biólogo Fernando Jiménez sea el nuevo Director del CIB sólo indica que todo continuará bajo el lema de investigar para servir a la comunidad y a la ciencia en general. . Jiménez tiene una gran responsabilidad, pero sabe enfrentarse a los retos. Por eso aceptó el nombramiento y ahora es la cabeza de esta familia de universitarios.

Fernando Jiménez Nuevo Director del Centro de Investigaciones Biológicas = Lo anterior indica la posibilidad de obtener proteínas a partir de un derivado del petróleo del cual México es potencialmente rico. Encontradas las condiciones óptimas de fermentación, se procedió a evaluar la levadura y pera ésto se efectuaron tres etapas: lo.- Evaluación química. Q. B. P. M. C. Baltazar Cuevas Hernández El proyecto "Obtención de Biomasa a partir de Etanol", se funda en el hecho de que México es potencialmente rico en petróleo y el etanol puede ser un derivado de éste, además de la facultad que tiene Saccharomyces exigus de usar el etanol como sustrato y finalmente la posibilidad de usar esta levadura en alimentación como fuente de pro• teína con miras a sustituir parcialmente la harina de soya la cual se importa en gran parte. Con lo anterior se lograría: lo.- Fomentar la investigación en. nuestro país. 2o.- Obtener adversidad en los métodos de obtención de alimentos. 3o.- Disminuir la fuga de divisas por importación de soya. Se aisló una levadura de la planta desértica 2o.- Evaluación de la proteína. 3o.- Ensayos en animales de interés comercial. PRIMERA ETAPA: Se puede resumir que la levadura contiene alrededor de 37 % de proteína cruda y con este valor con la harina de soya, la cual en gran parte se importa; ambas, la soya y la levadura son deficientes en metionina que es un aminoácido esencial. SEGUNDA ETAPA: Se puede resumir que al sustituir parcialmen• te la proteína de la soya por la proteína de la levadura en dietas para ratas, no se encontró diferencia significativa (PL 0.05) cuando se sustituyó la proteína de la soya un 20% con la proteína de la levadura. Esto significa incluir en la ración aproximadamente de 8 a 10% de levadura sin que las ratas muestren diferencia comparadas con una dieta control. El Biólogo Fernando Jiménez Guzmán, asumió el puesto de Director del Centro de Investigaciones Biológicas, cargo otorgado por el Rector de la UANL, Doctor Alfredo Piñeyro López. En una sencilla ceremonia presidida por el Di· rector de la Facultad de Ciencias Biológicas de la Universidad Autónoma de Nuevo León, Biólogo M. C. Cipriano Reyes Garza, asumió la dirección del Centro de Investigaciones Biológicas, el Biólogo Fernando Jiménez Guzmán, y ratificaron en su puesto como Secretario, al Biólogo Héctor González Aguirre. El nuevo funcionario universitario, sustituye al Biólogo Glafiro J. Alanís Flores, quien se hará cargo de la Coordinación del Proyecto de Silvicul• tura, Instituto próximo a crearse en Linares, Nuevo León, por instrucciones del Rector, Doctor Al· fredo Piñeyro López. Maestros y alumnos de esta Facultad estuvie• ron presentes en la ceremonia, que formó parte de otra etapa en la vida de este plantel. El nuevo Di rector del Centro de Investigaciones Biológicas de la U. A. N. L., Fernando Jiménez Guzmán, tiene un impresionante currículum de su brillante actividad académica y como investigador científico. Jiménez Guzmán, ocupa el cargo del Biólogo Glafiro J. Alanis Flores, quien a su vez, tendrá a su cargo una de las tareas a realizar que habrán de proyectar la imagen de nuestra alma mater en el campo de la investigación. Alanís Flores acaba de regresar de un mes de viaje de estudios por varias ciudades y Universidades de Estados Unidos, conociendo los alcances obtenidos en el campo de la Silvicultura. Ahora el Biólogo Alanís Flores, tendrá oportunidad de poner en práctica sus conocimientos, para conocer las riquezas de los recursos natura• les renovables y no renwables en estudios reali• zados en el Estado de Nuevo León. Al finalizar la ceremonia el Biólogo Cipriano Reyes Garza, exhortó a maestros y alumnos a trabajar, siguiendo el ejemplo de estos destacados maestros que tanto han colaborado a amplificar el prestigio de nuestra escuela y de nuestra máxima casa de estudios. Para hacerse cargo del Proyecto para la creación del Instituto de Silvicultura en la Universidad Autónoma de Nuevo León, el Doctor Alfredo Piñey• ro López Rei:tor de la UANL, nombró al Biólogo M. C.

Página 2 Página 3 �Datos Biológicos de la Codorniz escamosa Callipepla squamata castanogastris (Brewster) en el Municipio de Vallecillo, Nuevo León, México. la codorniz escamosa (Callipepta squamata castanogastris), es una gallinácea perteneciente a la familia Phasianidae. Su descripción es, plumaje gris pálido, las plumas de la parte anterior del dorso, costados y tórax, están bordeadas de un color negro y tienen un aspecto escamoso, lo cual constituye una característica distinta de esta especie, de donde de• riva su nombre. La cabeza y el cuello, son de una coloración gris café, así como la parte posterior del dorso, las alas y la cola; el pico es negruzco y las patas de un color gris cenizo. Poseen un copete blanquizco. Los sexos son similares, excepto que en los machos presentan una mancha de color café castaño rojizo en el abdómen, y en la garganta presenta un color mate ante; mientras que en las hembras la garganta es de color grisáceo con líneas café tenue. las medidas: longitud total (de pico a pata), 260 a 305 mm.; ala plegada, 110 a 120 mm.; cola, 75 a 90 mm.; pico 15 a 17 mm.; tarso, 28 a. 35 mm.; peso, 150 a 200 gramos. la distribución de la subespecie es, para el suroeste de Texas noroeste de Tamaulipas, noreste de Nuevo león, y noreste de Coahuila. Esta codorniz habita en zonas semiáridas, donde el suelo es en parte desnudo, con hierbas anuales, y con predominancia de mezquite, chaparro prieto y cenizo. Su alimentación, está constituida típicamente por semillas y ocasionalmente de insectos; durante la primavera y el verano, se alimentan con más frecuencia de graminea_s cultivadas (sorgo, maíz, trigo y escoba), no perjudicando al cultivo, ya que sólo se alimentan de los granos caídos. Durante otoño e invierno, las codornices se unen en parvadas desde 10 a 30 individuos, los cuales se comienzan a disociar a principios de abril, formándose luego las parejas; la época de nidación principia en mayo y continúa hasta agosto, los nidos son construidos en el suelo, cubierto por pequeñas ramas secas y plumón; cada nidada está constituida por un promedio de 14 huevos; los huevos son de color blanco opaco, con pequeñas manchas irregulares de color café, miden aproxi- Página 4 en la sombra de los árboles, encontrándosele con frecuencia descansando sobre el suelo; a las 4:00 p. M. comienzan de nuevo en busca de alimento y para las 6:30 P.M. o 7:00 P.M. regresan a sus refugios. En invierno su actividad diaria es de pocas horas (jurante el día, manteniéndose el mayor tiempo refugiados de las bajas temperaturas y las lluvias fuertes. Durante la noche las parvadas duermen en el suelo formando un círculo, dirigieñ• do cada una su cola al centro, estando así listas para emprender el vuelo juntas al detectar peligro cualquiera de ellas. la codorniz sólo habita lugares donde existan abastecimientos de agua, tales como ríos, presas, arroyos, abrevaderos de ganado y charcos; acostumbran abastecerse de agu¡i diariamente entre 4:00 y 5:00 P.M., después de esto, se mantienen alrededor de 30 ó 40 minutos reposando en ese lugar. La codorniz acostumbra caminar por caminos y veredas del ganado, para alimentarse de semillas que se encuentran en el estiércol del ganado, y con frecuencia se les ve entrar a los corrales del ganado vacuno para aprovechar las semillas que se dispersan al tragar rastrojo el ganado. Consumen pequeñas piedrecillas mientras se alimentan, las cuales son depositadas en la molleja para triturar bien el alimento. La densidad de la población es muy variable, se pueden encontrar desde 3 codornices por hec, tárea hasta una codorniz en 10 hectáreas. Según los datos observados, la paloma triste; y la paloma de alas blancas, reducen en parte el alimento de la codorniz. En algunas ocasiones se le encuentra conviviendo con la codorniz común madamente 34 x 25 mm., pesan alrededor de 9 gm., y su forma es cónica. El período de incuba• ción tiene una duración de 21 a 22 días; tanto la construcción del nido, como la incubación, y cuidado de las crías es llev¡¡do a cabo por ambos sexos. Desde que salen del huevo o un poco después, los polluelos pueden caminar, buscar su ali• mento, y aún cuidarse de sus enemigos con la ayuda de sus padres. Después de la eclosión los polluelos se mantienen juntos con sus padres for, mando una parvada familiar, y a principios de octubre se integran dos o más parvadas familiares formándose así las parvadas comunales que perduran hasta marzo. Desde marzo hasta septiembre la codorniz inicia su actividad diaria aproximadamente desde las 7:00 A.M., comenzando a buscar su alimento, para las 11 :00 A.M. se refugia de la insolación (Collinus virginianus). _-.-~¿,· ~ > :,. •·: ·,:~~~~~ -~ -·' _., ~ ~ - 1/ ·. ::;_;~:--- -,." ,·, . ; - ::... -'=-- ..-- . ____ _, .:. · .~- - -~-~-~~-~;-=~- ---?t ·:- la codorniz escamosa, es presa de diversos depredadores, principalmente aguilillas, gavilanes, lechuzas y coyotes.

Adjunto al Herbario se cuenta con material bibliográfico suficiente como para hacer posible una correcta determinación del ejemplar colectado, pero hay ocasiones en que se hace notar la falta de material bibliográfico lo suficientemente diversificado y especializado como para estar completamente seguro de su determinación. Ya el Dr. Rzedowski (1975), señaló los servicios de identificación e información que debe presentar un Herbario, asi como las tareas básiCl!S y demás actividades principales que desarrolla un Herbario. los servicios de identificación son una de las funciones más generales y mejor conocidos que se cumplen. A ésto es a lo que se le dedica la mayor atención por parte de los recursos humanos. Esta actividad se ofrece a manera de servicio al público, cuyos usuarios incluyen desde alumnos de la misma facultad o de otras instituciones afines que utilizan el material vegetal para la elaboración de sus tesis, hasta industrias regionales con interés en explotar una determinada planta. Además de las identificaciones, frecuentemente se hacen consultas relativas a las localidades exactas donde pueden encontrarse determinadas especies, asi como a la época en que pueden encontrarse en flor, en fruto o con ho¡as a las condiciones ecológicas en que prosperan' y muchas Por los Biólogos: Mauricio González Ferrara, Raúl Flores Olvera, Osear Briones y Ernesto Ramirez AGRADECIMIENTO: Queremos agradecer al Dr. Jorge S. Marroquin de la Fuente y al Centro de Investigaciones Biológicas de la Dirección General de la Investigación Científica, su valiosa cooperación en la elaboración de este trabajo. INTRODUCCION: El presente artículo se ha preparado con el propósito de dar a conocer las actividades que se realizan en el Herbario de Plantas Vasculares de la Facultad de Ciencias Biológicas de la Universidad Autónoma de Nuevo León, así como sus perspectivas y problemas fundamentales. Las colecciones que se encuentran depositadas en los diferentes herbarios, reúnen la importancia fundamental de servir como instrumento de trabajo y herramienta básica de la Botánica Sistemática, sin pasar desapercibida la enseñanza, la historia de la ciencia, la morfología y la anatomía vegetal, así como la etnobotánica, la farmacognosia, la conservación de los Recursos Vegetales, la Ecología Animal, el manejo de pastizales, el combate de malezas y otras plantas indeseables; a la vez que proporcionan los datos más exactos sobre los cambios de distribución geográfica de las plantas ocurridos en los últimos tiempos a causa de las actividades humanas. (Rzedowski, 1975). ANTECEDENTES: Las primeras colecciones de plantas de la Universidad Autónoma de Nuevo león, se obtuvieron en 1944 a través del Instituto de Investigaciones Cientlficas a cargo del Dr. Eduardo Aguirre Pequeño, fundador de esa Institución. Estas colecciones fueron hechas principalmente por el Profr. Antonio Hernández Corzo, quien realizó estudios botánicos de la Sierra Madre Oriental y alrededores de Monterrey; sus colectas formaron un pie de Herba• rio (1). Cabe destacar que dicho material no se encontraba depositado en lo que es propiamente un herbario o cualquier otro recinto con funciones conocidas, sino que se encontraba en cajas de cartón. Fue así, como en junio de 1957, el Dr. Jor• ge S. Marroquín de la Fuente (en aquel entonces estudiante de Biología de dicho plantel), rescató ese material y se encargó personalmente del montaje y etiquetado de las plantas para comenzar lo que fue en sí el Herbario; por lo que se considera el mes de junio de 1957, como Ja fecha de su fundación . Además, por varios años, estuvo al frente del mismo, incrementado el número de ejemplares con sus propias colectas. Después, en el año de 1962, el Instituto de Investigaciones se redujo consideráblemente a una oficina de la Universidad Autónoma de Nuevo león y la colección botánica pasó a ser propiedad de la escuela, hoy Facultad de Ciencias Biológicas. Entre otras personas que se preocuparon por el desarrollo y cuidado del Herbario en aquella época, podríamos citar a los Biólogos Glafiro J. Alanís Flores, Humberto Sánchez Vega, Paulina Rojas Mendoza y José luis Gutiérrez lobatos entre otros. Actualmente trabajan en el Herbario un gran número de personas, principalmente en la elaboráción de trabajos de tesis, dando por resultado un gran incremento en el número de ejemplares. Cabe destacar la labor desarrollada por el Biólogo José A. Villarreal Quintanilla, quien actualmente es maestro investigador y encargado del Herba- ria de la Universidad Autónoma Agraria "Antonio Narro" , Saltillo, Coahuila; y quien en varios años en forma desinteresada, se dedicó al Herbario de la Facultad de Ciencias Biológicas de la U. A. N. L. El Centro de Investigaciones Biológicas, a tra, vés de sus diferentes proyectos de investigación, ha incrementado en forma significativa el número de ejemplares, impulso que no se había dado en ningún otro tiempo. Tal proyección hace del Herbario Fanerogámico un fuerte pilar de la infraestructura científica de la propia Universidad Autónoma de Nuevo león. FUNCIONAMIENTO: El Herbario de Plantas Vasculares se localiza dentro de la Facultad de Ciencias Biológicas de la U. A . N. l., el espacio físico ocupado por el herbario consta de: dos cubículos, un área de trabajos donde se procesa el material vegetal y el Herbario en general. Su parte esencial consiste en una colección de plantas secas, debidamente preparadas y montadas sobre cartulinas. Cada ejemplar va acompañdo de su respectiva tarjeta en la que lleva su nombre científico, así como los datos correspondientes al sitio de colecta, el nombre común, el colector o colectores, etc. El conjunto está arreglado de una manera alfabética, de tal manera que permite fácil consulta de cada es- Página 6 Página 7 �con 836 ejemplares en 80 géneros; Euphorbíaceae con 380 ejemplares en 19 géneros y Fagaceae con 275 ejempíares en 2 géneros. De Pteridophyta o helechos, la familia mejor representada es Polypodiaceae, con 283 ejemplares repartidos en 24 géneros. La colección comprende principalmente la flora de los matorrales desérticos de los estados de Coahuila, Nuevo León y Tamaulipas; las regíones de la Sierra Madre Oriental, la Planicie Costera del Golfo y el Altiplano; pinos y encinos del Estado y/o plantas útiles regionales. Además, se cuenta en menor proporción, pero no menos importante, con especímenes de otras regiones del país y del extranjero (principalmente Estados Unidos), los cuales han sido obtenidos a través de intercambios con otros herbarios. Se cuenta con una pequeña Xiloteca donada por el Instituto Nacional de lnvesti¡pciones Forestales. COLECCIONES IMPORTANTES: .. preguntas diversas sobre plantas que por lo general pueden encontrarse gracias a la información contenida en el Herbario. Una característica frecuente de cualquier Herbario funcional es su crecimiento. La actividad desarrollada dentro del Herbario se ha llevado a cabo a un ritmo lento pero constante. Este crecimiento se realiza mediante adquisición de material botánico nuevo que puede proceder de fuentes diversas. Los mecanismos más comunes de adquisición son: Colectas realizadas por el personal del Herbario, así como también de los profesores, investígadores y alumnos de la institución. Intercambio con otros herbarios del país, y por material recibido para identificación. MATERIAL DISPONIBLE: • w El número de ejemplares que se encuentran depositados hasta la fecha es de 11,400 comprendidos en 202 familias, con 1,208 géneros, quedando 190 familias y 1,170 géneros en las Fanerógenas y 12 familias y 38 géneros en las Pteridophyta. Dentro de las Fanerógamas, las familias que están mejor representadas son las siguientes: Com, positae con 1,380 ejemplares, 148 géneros y aproximadamente 356 especies; Gramineae con 1,073 ejemplares dentro de 91 géneros; Leguminosae Página 8 En sus inicios destacan plantas colectadas por Fred A. Barcley, Antonio Hernández Corzo, B. C. Tharp, B. C. Warnock, C. H. Muller, Bruce Zobell, B. L. Turner, Franklin Cech, en la década de los cuarentas y posteriormente, J. S. Marroquín, Jerzy Rzedowsky, Paulina Rojas Mendoza, Humberto Sánchez V., Glafiro J. Alanís Flores, José Luis Gutiérrez L., y José A. Villarreal. PROBLEMATICA: El Herbario de Plantas Vasculares de la U. A. N. L., no escapa a los problemas que de manera general afrontan todos los Herbarios del país. Quizá estos problemas se agudizan más por ser éste, relativamente, un Herbario pequeño La falta de presupuesto destinado específicamente al Herbario y de proyectos de investigación que le sirvan de apoyo, genera que al interior no exista una biblioteca especializada y que el espacio fí. sico sea muy reducido. Actualmente no existe personal de planta o de media planta en el Herbario. Este personal lo han formado maestros que dedican el poco tiempo libre que no les absorbe la cátedra al trabajo de herbario acompañados de tesistas y alumnos que realizan servicio social. Sin embargo, a pesar de toda la serie de problemas que se derivan de los anteriores, el Herbario es una institución viva que ha estado creciendo e indudablemente así seguirá, y si entendemos• lo que significa el Herbario en cuanto a la investigación y la enseñanza, y que además representa no solo a la U. A. N. L . sino al Estado de Nuevo León, entenderemos que el desarrollo adecuado del Herbario es una tarea en la que de una forma u otra, todos debemos participar. � Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Si aunamos la infraestructura, la explosión demográfica, la venta de pieles y mil cosas más, ésto ha dado como resultado un funesto futuro de la fauna cinegética de nuestro Estado. Esta información, tendrá un gran valor, cuando los futuros investigadores la usen como parámetro en sus estudios mastozoológicos. 1 N D I C A D O R : Alfredo Piñeyro López, Rector.- lng.

EL BIOLOGO BRISEÑO OCUPA PUESTO ADMINISTRATIVO El Biólogo Carlos H. Briseño de la Fuente, asumió el cargo de Sub-Director Administrativo de la Facultad de Ciencias Biológicas de la U. A. N. L., en sencilla ceremonia efectuada en el despacho del Director Biólogo Cipriano Reyes Garza. Breve y sencillo, el Biólogo Briseño se pronunció en llevar una poi ítica de puertas abiertas. "debemos tener diálogo", los Maestros y alumnos, aquí en la Facultad debemos de luchar juntos, acabar con las divisiones en bien de la Institución. Por su parte el Biólogo Cipriano Reyes Garza, Director de la Facultad señaló que se daba un paso adelante con la nominación del Biólog~ Briseño, "ya que es una persona de amplia experiencia en la rama de administración y conoce la tónica de trabajo de esta Institución. El Biólogo Carlos H. Briseño de la Fuente, ocupó el cargo de Sub-Director Administrativo de la Facultad de Biología de La U. A. N. L. LA IMPORTANCIA DE LOS POLIQUETOS (ANNELIDA: POL YCHAETA) EN EL MEDIO MARINO Por: Sergio Ignacio Salazar-Vallejo Lab. Zoología de Invertebrados No-Arthropoda Facultad de Ciencias Biológicas de la U.A.N.L. Los poliquetos (Gr. POL Y muchas + CHAET AE = setas) son anélidos que generalmente ostentan proyecciones de la pared corporal o parapodios (Gr. PARA= lateral + PODIA =pies) provistos de estrucuturas esclerosadas de naturaleza quitina-proteínica llamadas setas, cuyo número generalmente abundante sirve para distinguirlos de los oligoquetos (Gr. OLIGOS =pocas + CHAETAE) Su biología general puede hallarse en cualquier texto de zoología de invertebrados o en las obras de Fauvel (1959) o de Dales (1967). Han sido descrita¡ más de 10,000 especies de poliquetos en todo el mundo; la mayoría habitan el medio marino, aunque hay algunas especies dulceacu ícolas e incluso otras pocas han sido reportadas del medio terrestre. En el mar, los poliquetos se presentan con mayor abundancia en el fondo (bentos) o flotando permanentemente en el agua (plancton). Las especies planctónicas son predatoras de otros animales o larvas pelágicas incluyendo las larvas de peces; algunas de ellas, agrupadas en la familia Alciopidae, poseen ojos enormes que pueden formar imágenes como los ojos de vertebrados, cefalópodos y atrópodos. Por otro lado, las especies bénticas exhiben una complejidad mayor en cuanto a la manera de obtener su alimento se refiere (ver Fauchald & Jumars, 1979, para una revisión de los patrones alimentarios de los poliquetos). Los vermes poliquetos son usualmente el grupo de metazoos más abundante de algunos medios, tales como sitios polucionados, impolutos, bahías constru ídas por el hombre e incluso comunidades abisales, y son de los más abundantes en playas arenosas, criptofauna (Gr. KRYPTO = oculto) coralina y epifauna de ciertos moluscos y corales. Como consecuencia de su abundancia, modifican el sustrato que habitan. El sustrato duro es modificado por la formación de tubos calcáreos como los de los miembros de las familias Serpulidae y Spirorbidae, que transforman la tersura superficial, aumentan su fricción relativa y contribuyen a su corrosión. Esto se presenta en cascos de embarcaciones, pilotes de muelles y postes de plataformas petroleras, donde ocupan el segundo lugar, después de los balanos, entre los organismos dañadores (ten Hove, 1979) que se denominan colectivamente en inglés "fouling" . Se ha observado que alcanzan números impresionantes en los túneles que conducen agua marina para enfriamiento en las plantas nucleares y como obstruyen el flujo del agua, deben removerse periódicamente. Los poliquetos modifican considerablemente el sustrato blando, forman galerías que cambian las condiciones de oxigenación y acarrean partículas del fondo hacia la superficie y viceversa jugando un papel similar al de las lombrices de tierr? (ver Knox, 1977, para una revisión del pape de los poliquetos en el sustrato blando), y modifican la consistencia del sustrato con sus tubos de materiales variados. Por ejemplo, los miembros de la familia Sabellariidae forman arrecifes arenosos y como son muy selectivos en cuanto al tamaño de las partículas con que construyen sus tubos, modifican la composición granulornétrica de las playas adyacentes. Una modificación especial es la ocasionada por los poliquetos "cultivadores" de algas (Woodin, 1977), ya que. facilitan la colonización del sustrato por el alga y como consecuencia de la humedad retenida, reducen el impacto de la salinidad y Ía desecación en su ambiente sito en la zona intertidal de algunas playas arenosas. En cuanto a la relación poliquetos-polución, algunos de ellos como Capitella capitata (familia Capitellidae) son considerados como indicadores de contaminación orgánica. Otra especie, de la fa. mi lia Nereidae, Neanthes arenaceodentata, ha sido propuesta como modelo para la toxicología citogenética marina, y en otra, de la familia Glyceri°dae, Gycera alba, se han propuesto y realizado métodos bioquímicos para estudiar el efecto de la polución orgánica. En adición , los poliquetos proporcionan la respuesta más rápida de la fauna béntica a cualquier perturbación ambiental (Simon & Dauer 1977) aunque esta sea moderada y de origen orgá'. nico (Dauer & Conner, 1980). Otra consecuencia de la gran abundancia de los poliquetos es su importancia en la redes tróficas del bentos. Esta importancia se ha demostrado en las dietas de algunos peces demersales (que viven en el fondo). Otras especies, como Nereis virens (familia Nereidae) y Glycera dibranchiata (familia Glyceridae), se han usado como camada para la pesca deportiva y en algunos lugares de los Estados Unidos, estas especies son comúnes en la dieta norm;¡I de algunas comunidades humanas, Más sorprendentes aún son los banquetes de los "palolos"; esto es, �algunos poliquetos presentan formas especializadas para la reproducción (epitocas), que en una época del año y bajo ciertas condiciones ambientales, salen de sus tubos en números tan grandes que un remo puede mantenerse erecto. Así sucede con Eunica viridis : (familia Eunicidae) el palolo de Samoa, dciñiie tal abundancia se traduce en un festín para peces y pájaros e incluso para los aborígenes samoyanos que los comen en medio de celebraciones ( Fránces, 1967). Algunos poliquetos han recibido considerable atención por su relación con algunos bivalvos de importancia comercial. Tal es el caso de las especies del género Polydora (familia Spionidae) que habitan. sobre las conchas de ostiones. Cuando el poliqueto alcanza la cavidad del manto, el molusco forma una nueva capa con el fin de mantener al gusano fuera del cuerpo del mismo, en esa cavidad se acumulan las heces del poliqueto y se forma una mancha o lunar de fango que reduce el valor del molusco pero no afecta al bivalvo. Sin embargo, en ocasiones la infestación es tan alta que los ostiones mueren, pero no por acción directa de los espiónidos, sino porque estos contribuen a la formación de un ambiente detrimental que a su vez causa la muerte del ostión (Owen, 1957). A pesar de la enorme importancia de este grupo, ha recibida poca atención de parte de los zoólogos nacionales. El Dr. Enrique Rioja, sabio español venido a México cuando la guerra franquista, realizó abundantes reportes sobre la poliquetofauna de nuestras costas en el período de 1939 a 1962; lamentablemente, parece que su colección se ha perdido (Caso, com. pers.) Pasaron 14 años para que alguien en México se interesara por los poliquetos; en 1976, el Dr. Miguel A. Marrón-Aguilar realizó un estudio sobre los poliquetos de la Laguna de Términos, Campeche, y formó una colección de 44 especies que quizá esté en el Lab. de Invertebrados de la Universidad Autónoma Metropolitana (lztapalapa). En la Estación Mazatlán de la Universidad Nacional Autónoma de México, poseen una colección de 98 especies que recientemente revisé, que no ha sido formalmente reportada. En nuestra institución, poseemos una colección que empezó a formarse en 1964 y que procede de viajes de colecta y donativos con materiales provenientes de 1 localidad del extranjero (U.S.A.) y 11 localidades de 7 estados costeros mexicanos. Posee 74 especies de 59 géneros que pertenecen a 26 familias colocadas en 9 ordenes, adecuadamente preservadas y catalogadas que se han reportado en mi tésis, por lo que es la colección más grande de México, exceptuando la de Mazatlán que no ha sido reportada. La colección de la Universidad Autónoma de Nuevo León está depositada en ~I Laboratorio de Zoología de Invertebrados No-Arthropoda de la Faculta de Ciencias Biológicas y se esta incrementando constantemente con materiales colectados por personal del mismo Lab. y por materiales enviados pidiendo su identificación. Así entendido el panora_ma de las colecciones zoológicas está cam'. biando comparado con lo expuesto recientemente (Contreras-Balderas, 1978). Y la importancia de esta colección, como de cualquier otra, es la de contribuir al conocimiento de los recursos reales o potenciales de una región, para optimizar su utilización.

Arturo Jiménez Guzmán Nuevo León posee tres regiones fisiográficas: la Planicie Costera del Golfo, la Sierra Madre Oriental y el Altiplano Mexicano. La más extensa de estas tres regiones es la Planicie Costera del Golfo, que tiene 36,000 Km.2 (Jiménez: 1966), cuya vegetación es típica de zonas áridas o semiáridas, . La Sierra Madre Oriental con 17,000 km.2, está far• mada por montañas cuya anchura varía de 30 a 80 Km. y elevaciones sobre el nivel del mar hasta 3,625 mts., como el Cerro del Potosí en el Municipio de Galeana. La vegetación característica de esta región es la de bosque mesofítico (pino-encino-abeto) y chaparral templado (encino-bosque mixto). El Altiplano Mexicano es la porción más corta, 12,000 Km.2, la ausencia de ríos y clima extremoso es una característica de esta región. Pequeñas sierras y vegetación semidesértica y desértica con suelos coluviales y aluviales cubren esta área. La fisiografía del Estado de Nuevo León, presenta hoy en día zonas ecológicas características, donde los elementos naturales de topografía, clima, suelos y vegetación, se conjugan para intervenir, directa o indirectamente, en la ubicación, distribución y "protección" de la fauna silvestre. Esto dá como resultado, que existan 122 especies de mamiferos reportados para el Estado . De ellas, 39 tienen en alguna forma relación con la fauna cinegética; 5 especies están desaparecidas; 2 están en proceso de desaparecer y 4 están en peligro de desaparición. En las zonas áridas y semi áridas de la Planicie Costera , del Golfo, existen 4 especies y una subespecie . endémicas. Las especies cinegéticas más codiciadas son el Venado cola blanca (Odocoileus virginianus). el Oso negro (Ursus americanus), el Jabalí (Tiyassu tajacu). Gato de cola rabona (Lynx rufus). Liebres Lerus californicus merriami), Conejos (Syivliagus floridanus y quizés el Puma (Felis ~ color). En esta área, el Castor (Castor canadensis) Fig. 1 especie endémica de esta región en el Estado que está en peligro de desaparecer, ya que de acuerdo a los estudios realizados por Landín y Jiménez (1981) en 860 Kms. de longitud de la mayoría de los ríos y alfuentes que irrigan la Planicie Costera del Golfo, se localizaron 64 colonias de castores activas, se observaron 17 diques y el número no sobrepasaba de 256 ejemplares. Esta especie desaparecerá de arroyos intermitentes para fines de la década y del río San Juan, el más caudaloso de Nuevo León, para fines del siglo. En la Planicie Costera del Golfo, existe el Venado cola blanca (Odocoileus virginianus), más corpulento, sus astas abiertas con mayor número de puntas, se localizan en China, Bustamente, General Bravo y Parás. Este se constituye, dentro de los mamíferos, como una de las especies cine• géticas más codiciadas del Estado. La Sierra Madre Oriental, encierra sus atractivos en las extensas zonas de pino-encino. 4 especies endémicas en esta región en el Estado. Dentro de las rnás importantes está el Oso negro (Ursus americanus), que de acuerdo a los estudios realizados durante 1980 y 1981, se considera en proceso de desaparición, ya que todavía se localizan áreas en donde se les puede observar. El Jaguar, que al principio de la década pasada ocasionalmente aparecía en esta zona, es quizá , sobre todo en el cerro Peña Nevada, en el cerro El Viejo y otros que colindan con Tamaulipas, donde "accidentalmente" pueden llegar, pero en estos últimos años no se ha tenido noticia de la presencia del tigre americano, por lo que se considera desaparecido. El Puma (Felis concolor). es más común que el félido anterior, pero seencuentra en las áreas más distintas y abruptas de la sierra. El Jaguarundi (Felis yagouaroundi) es dentro de los félidos, una especie qüeliab1ta los ecotonos de la Sierra Madre Oriental y la Planicie Costera del Golfo, es raro. Un ejemplar donado a esta Institución, en su contenido estomacal reveló carne de conejo (Sylvilagus sp.), no se encontró ningún hueso. - · El Altiplano Mexicano, enclavado en el Suroeste de Nuevo León, se caracteriza por la ausencia de ríos, vegetación desértica o semidesértica y clima extremoso.

Dr. Ramiro González Garza. Responsable del Proyecto La Escuela de Graduados de la Facultad de Ciencias Biológicas de la Universidad Autónoma de Nuevo León, en coordinación con el Departamento de Pesca y la FAO, organizaron en días pa• sados un Curso Internacional de Alimentos Rústicos para la Piscicultura. El evento tuvo como objetivo, buscar una solución al desarrollo de nuevas tecnologías de producción de alimentos y preservación del ambiente. El doctor Kai W. Chow, prestigiado investigador mundial, fue el encargado de impartir el curso. Asimismo, se realizó un Seminario sobre Truticultura y Especies en Peligro de Extinción, teniendo como sede la Escuela de Graduados de la Fa• cultad de Ciencias Biológicas de la U.A.N.L. a cargo del Dr. Salvador Contreras Balderas. PUBLICARAN TRABAJOS Importantes estudios sobre el conocimiento de la Flora Micológica Mexicana serán publicados en el boletín que edita la Sociedad Mexicana de Micología e_n ~oordinación con el Centro de Investigaciones B1olog1cas y el Laboratorio de Micología de la Facultad de Ciencias Biológicas. MICROSCOPIOS Buena es la labor que desarrolla la Administración de Ciencias Biológicas que encabeza Cipriano Reyes Garza, por lucha no queda, en lo que va del año se han adquirido un total de 200 microscopios con una inversión aproximada de 5 millones de pesos y a punto de cristalizar el proyecto del nuevo edificio contiguo al actual que fun, cionará como Laboratorios y Cubículos para maestros . ¡Enhorabuena! señor director. INVITAN La División de Estudios Superiores de la Facultad de Arquitectura de la U.A.N.L., promueve entre los alumnos de 60., 7o., 80. y 9o. Semestre de Biólogos, la Maestría de Ciencias para la Planificación de Asentamientos Humanos. La maestra Lucila Beatriz Martínez, coordinadora de la Maestría, sostuvo una entrevista con el Biól. Manuel Torres, encargado de la Carrera de Biólogos en la Facultad de Ciencias Biológicas. VISITAN SAN FERNANDO, TAMPS Una comisión integr¡ida por los Biólogos Ci. priano Reyes Garza, Director de la Facultad de Bio• logia, Fernando Jiménez Guzmán, Director del Centro de Investigaciones Biológicas, Héctor González PAGINA 2 Aguirre, Secretario del C. l. B. y el lng. Roberto Mercado se entrevistó con el Alcalde de San Fernando, Tamps., Daría Pérez Barquiarena y plantearle la necesidad de establecer una estación hidrobiológica en las márgenes de la Laguna Madre, específicamente en la zona denominada "La Car, bonera". Y AUN HAY MAS . .. También en días pasados los Biólogos Héctor González Aguirre, Arturo Jiménez Guzmán, Jefe de Relaciones Públicas de la Facultad de Ciencias Biológicas y el Biólogo Fernando Jiménez, Director del CIB se entrevistaron con distintas auto• ridades tamaulipecas. En el recorrido que hicieron por el vecino estado se obtuvieron pláticas con el lng. Manuel Flores, Director de Pesca de Tamaulipas, así mismo con el Dr. Héctor Capello, Coordinador de Estudios Superiores de la Universidad Autónoma de Tamaulipas. Por último, tuvieron pláticas con el Director de Turismo, Eugenio Hernández Balboa. APOYO La doctora Mercedes Velazco, Coordinadora del Programa Nacional Indicativo de Ecología del CONACYT, se mostró interesada en cooperar con el Centro de Investigaciones Biológicas de la ~.A. N. L. , en apoyo a nuevos proyectos, posterior a una charla que sostuvieron el Biól. Héctor González Aguirre, Secretario del C. l. B., y el Di•· rector del mismo Fernando Jiménez. Aprovechando su viaje por el D.F., los funcionarios del CIB charlaron con el Dr. Edmundo de Alba, Director de la Dirección General de la Investigación Científica y Superación Académica de la S. E. P. y aprobó la intención de trabajar en forma mutua elogiando a su vez la labor desarrollada por el Centro de Investigaciones Biológicas de la UANL. VIAJE DE ESTUDIOS Un grupo de estudiantes al realizar una gira por el estado de Michoacán, visitaron la Universi• dad de San Nicolás de Hidalgo, la Facultad de Agronomía, Resinera y una Maderera y realizaron colectas de material botánico y entomológico para que sean analizados en los· laboratorios de la Facultad de Ciencias Biológicas. Los Biólogos Lucre• cia Garcfa y Edmundo Barbosa encabezan el grupo de 38 alumnos del sexto semestre de Biólogos, de las materias Botánica y Entomología. Cooperativo de Virología Vegetal INIA-UANL La investigación que se realiza en la Universidad Autónoma de Nuevo León, adquiere cada día más importancia gracias al apoyo brindado por la federación, el Estado y organismos privados. Las autoridades universitarias (Rectoría, Dirección General de Investigación, Centros de In• vestigaciones y Direcciones de Escuelas y Facul.tades) están luchando fuertemente para captar Y ampliar los cada vez mayores recursos económicos dedicados a investigación. Prácticamente todos los proyectos de investigación bien fundamen· lados, presentados en las Facultades y Escuelas, son aprobadas en el 10% de los presupuestos solicitados, lo cual constituye un innegable síntoma de apoyo a los mismos . En pocas palabras, la investigación está finalmente eferveciendo y creciendo en nuestra máxima casa de estudios y pasando lentamente de la fase imitativa a la fase creativa. La investigación es la fase culminante del entendimiento humano. Todos y durante todas las etapas de nuestras vidas "Investigamos cosas" y disipamos dudas; sin embargo, cuando las dudas sen más difíciles de contestar, nuestra investigación se vuelve más estricta, tenemos 4ue adoptar una metodología científica, enseñarnos a usar esta metodología, dedicarle el tiempo y el presupuesto necesarios y lanzarnos en la búsqueda de la respuesta. Entonces, la investigación requiere de tiempo, presupuesto y del trabajo especailizado de gentes entrenadas en metodología científica y todo esto se traduce en una alta inversión (costo) a la Universidad. Por estas mismas características, la investigación sólo puede ser realizada por Escuelas, Facultades e Institutos que tienen la infraestructura material y humana que las "acredita como mayores de edad" y tomando el contexto general de enseñanza en el Estado, pocas son las instituciones que tienen el privilegio (por el costo que representa) de realizar investigación. Sin embargo, no debemos de olvidar que estas instituciones privilegiadas a las que los contribuyentes (a través de pn¡supuestos Federales, Estatales, etc.), les han depositado su confianza y su esperanza en la investigación que realizan, tienen la obligación de velar por que esta investigación sea eficaz y eficientemente planeada y desarrollada para que cumpla con los objetivos y metas propuestos. Optimizar la investigación, es producir más y mejores resultados al menor costo posible de los contribuyentes; planear el "qué" investigar, representa el principal problema de los investigadores Y de los organismos encargados de escoger los proyectos, que se les dará apoyo económico y ésto debe obedecer a una jerarquización de problemas, oportunidades y/o necesidades de la sociedad en que vivimos. Desarrollar la investigación planeada dentro del espacio y tiempo programados es misión conjunta de investigadores y ·autoridades que administran la investigación y es precisamente aquí, en el desarrollo de la investigación misma, donde · encontramos los principales obstáculos para réalizarla. Normalmente queremos realizar in• vestigación con las misma infraestructura y mentalidad académica que nos hemos forl)1a~o en primaria, secundaria, y en preparatoria,. do_nde la cátedra teórica es el objetivo y la finalidad de su educación. En esta forma, la cátedra se puede suspender durante un período vacacional de 15, 20 ó más días, mientras que un experimento biológico, difícilmente puede descuidarse 24 horas; un corte de energía eléctrica en un fin de semana ni si•· quiera es percibido en una escuela primaria y puede ser el fin para muchos experimentos en invernaderos de temperatura controlada, incubadoras, o para compuestos químicos o biológicos que requieren congelación. En esta forma podríamos citar un gran número de ejemplos más, en los cuales podremos notar fácilmente la diferencia que debe de existir entre una Institución de investiga• ción con las de enseñanza básica. Cuando decimos que la investigación se debe de realizar en instituciones que han obtenido su "mayoría de edad" nos referimos a que han sabido superar su mentalidad de escuela de primaria o secvndaria, (donde la investigación no es su objetivo) y han podido garantizar la continuidad de su investigación a través de vacaciones, puentes, fallas de corriente eléctrica, retrasos en presupuestos u ·otras causas. De nada nos sirve que se aprueben proyectos de investigación que cuestan millones de pesos, si no podemos ofrecer las condiciones necesarias para que estos se desarrollen eficientemente y logren su feliz término. Trabajar hasta obtener las condiciones óptimas necesarias para que la investigación se desarrolle eficientemente, es la tarea que profesores investigadores y autoridades universitarias tenemos que realiz_ar. Si queremos que nuestra institución tenga el honor y el privilegio de realizar investigación, debemos tener también la obligación de garantizar que ésta se realice eficaz y eficientemente por respeto al pueblo que paga y espera los resultados emanados de la misma. PAGINA 3 �cuentran sus hospederos intermediarios en caracoles y peces. Se hace patente y necesario la elaboración de leyes lctiosanitarias que regulen o que reglamenten la introducción de peces, creación de presas o vasos de almacenamiento, MONITOREO DE HELMINTOS PARASITOS DE PECES DULCEACUICOLAS EN MEXICO etc. Por los Biólogos Carlos H. Briseío de la Fuente, Femando Jiménez Guzmán y Gerardo Guajardo. 5.- En base al punto 3 y 4, es posible hacer una SU IMPORTANCIA Y SU VALOR COMO INDICADORES DEL IMPACTO AMBIENTAL La República Mexicana tiene en su territorio más de 150 ríos importantes, sin contar un ele vado número de lagos. presas, arroyos, etc., siendo todo esto un conjunto hidrográfico importante. Actualmente con el impulso que se está dando a la creación de presas tanto por el Gobierno como por particulares, se visualiza que en un futuro muy próximo, se formarán núcleos de población que se dediquen a las artes de la pesca, ya sea para cubrir un renglón en su dieta alimenticia, o pesca y cultivos masivos para atender las demandas locales. Desgraciadamente en México no se ha llegado totalmente a esta última escala, pero si a la que corresponde a pesca recreativa, centros re, creativos {ejemplo: Presa la Boca, Lago de Pátzcuaro, Michoacán, Presa Falcón, etc.) en donde la afluencia de turismo (deportistas) trae como consecuencia nuevas fuentes de trabajo (comerciantes, guías, lancheros, etc) además de estas fuentes de trabajo, es importante mencionar que en México existen especies de peces endémicos y/o exóticos, las cuales pued_en ser susceptibles a explotación como especies de acuario novedosas. Muchas veces un factor limitante para la explotación de peces dulceacuícolas son las enfermedades parasitarias, especialmente las que son causadas por helmintos y protozoarios, sin olvidar las originadas por virus, bacterias, algas, hongos, anelidos, fases larvarias de moluscos (almejas: (Unionidae) artropodos. En muchas partes del mundo en especial la Unión Soviética Estados Unidos de Norteamérica, Alemania y otr~s países europeos el estudio de los parásitos de peces ha alcanzado un alto nivel de desarrollo. En México, no obstante los importantes trabajos sobre Taxonomía de helmintt>s de peces marinos se han descuidado desgraciadamente los pece~ dulceacuicolas, prueba de esta deficiencia son los escasos trabajos científicos realizados de 1891 por Alemán, a la fecha. Como se puede constatar, el número de trabajos en México son muy escasos. De lo anteriormente expuesto se puede concretar, que el estudio de los helmintos ~e pece~ dulceacuícolas de México, es muy reducido, casi nulo. De aquí la importancia de establecer: 1.-· El número de especies de helmintos que parasitan a peces dulceacuícolas de México, PAGINA 4 Una de las principales parasitosis de peces es provocada por larvas de tremátodos, en este caso por Clinostomum sp. en Bagres lctalurus. para lo cual es necesario elaborar estudios taxonómicos encaminados a la identidificación de estos helmintos, tanto en fase adul, ta como larvaria. 2.- Determinar, en base al punto No. 1, la presencia de posibles helmintos potencialmente parásitos del hombre o los animales domésticos, como por ejemplo: tremátodos de la familia Heterophyidae, Clinostomidae, Opisthorchiidae y otros helmintos. 3.- Establecer el índice de parasitosis de los peces en las áreas de estudio, en especial de especies de importancia económica o deportiva, además de las forrajeras, ya que éstas pueden servir tanto como control biológico de ciertas enfermedades del hombre, (eJemplo: sardinas comedoras de larvas de anafe• linos trasmisores de paludismo) o ser ali· mento de otros peces mayores (deportivos o de importancia económica) por lo cual pueden ser éstas también transmisoras de otras helmintiásis . Es importante también estu• diar y evaluar la acción patológica que pueden ejercer estos helmintos en el hospedero, tanto en fase adulta como larvaria. 4.- En base al punto No. 1 y 3, se puede evaluar el impacto ecológico que puedan provocar nuevas obras hidráulicas. Por eiemplo se ha observado, que por la creación de nuevas presas, los rios sufren al rasar el tiem· po, un incremento en la cantidad de sales en sus aguas, por lo que trae como consecuencia que muchos peces de habitats eurihalinos se encuentren muy distantes de su lugar de origen, lo que trae como consecuen- En muchos casos las Metacercarias (Larvas de Tremátodos) puede provocar la muerte de los peces cuando éstos se sujetan a un stress . Los peces que se aprecian en la foto, al ser captura- dos numeros2s larvas emergieron del hospedero provocando su muerte. cia una transfaunación de parásitos rio arriba. En otros casos, la introducción de peces no nativos a otros habitats, trae como consecuencia una transfaunación de · parásitos, los cuales en un momento dado, pueden cau~ar un desequilibrio ecológico sobre las especies nativas o viceversa. Este tipo de problemas se acentúa más después de varios años de construida una presa; los primeros años no se presentan problemas p_arasitol?gicos, porque todavía no se estabiliza el sistema e~ológico, en donde los peces y hospede~os intermediarios de parásitos, apenas comienza~ a integrarse a los ciclos de las cadenas ah· mentidas; después de este período, los pro· blemas parasitarios se present~n e~ forma significativa, por ejemplo: El hacin~m1ento ~e peces y desarrollo de hospederos int~r~ed1arios, que en combinación con la _v1s1ta de aves ictiófagas migratorias, causan estas una transfaunación, como es el caso en especial de tremátodos digéneos, los cuales en- evaluación económica desde varios puntos de vista, por ejemplo: es sabido que en peces comerciales, cuando el indice de parásitos pór hospedero es muy alto, trae como consecuencia la. muerte o una baja notable en peso, crecimiento y retardo en su madu• rez sexual. En peces deportivos, sucede una situación similar, pero se agrega la que al departista ya no le atrae ir de pesca a esa determinada presa o río, (los peces dan un aspecto muy desagradable a la vista del deportista o consumidor por la presencia de sus parásitos, además el tamaño y peso es muy pequeño), lo que trae como consecuencia una reducción de los ingresos económicos en las personas que viven del turismo y la pesca en pequeña escala, (casos con• cretas son: Presa la Ceja, China, N. L., e In• fiernillo). 6.- Es importante tratar de establecer algunas posibles medidas de control en las áreas donde los índices de parasitosis son muy elevadas y tengan repercusión en el desarrollo normal de los hospederos, para este propó• sito es recomendable hacer un reconocí• miento de las fases iniciales de los parásitos en sus hospederos intermediarios cuando éstos existan, además de relacionar los parásitos de otros vertebrados acuáticos que compartan el mismo habitat, en virtud de que algunos peces pueden ser hospederos intermediarios de los parásitos de estos vertebrados ictiófagos. Otras de las Parasitosis más frecuentes en peces son las provocadas por larvas de Nemátodos como las que se observan en este Robalo (Lobina) Micropterus salmoides. PAGINA 5 �BASES TEORICAS DEL SISTEMA FOTOGENETICO 11 REUNION NACIONAL DE COORDINADORES DE MODIFICACION DEL TIEMPO DE INVESTIGACION YESTUDIOS DE POSGRADO . •' N. de R.- Un grupo de profesionales mexicanos, estructuraron un sistema fotogenético cuya aplicación dio como resultado la obtención de lluvias en zonas desérticas, áridas o semiáridas. El estudio ufe realizado en el estado de Chihuahua en el ano de 1978 contando con el apoyo total del Gobernador en ese entonces, Sr. Manuel Bernardo Aguirre. En el presente documento se hace una ex• posición de las bases teóricas y de los probables fenómenos involucrados en la aplicación de nues• tras técnicas de modificación de ciertos factores meteorológicos. Es deseable, sin embargo, men• cionar primero algunas generalidades sobre el fun• cionamiento termodinámico de la atmósfera terres• tre: a) El aire tiene una capacidad de contener vapor de agua, que varia en función de su tempera, tura. b) La cantidad de vapor de agua que contiene el aire en un momento dado, se denomina hume• dad absoluta. Si relacionamos este parámetro con la humedad que podría contener el aire si estuviera saturado, obtendremos un porcentaje; es decir, la parte del total de vapor de agua que puede contener el aire y que contiene en ese momento. A este porcentaje se le llama humedad relativa. c) Prácticamente toda la energía de la atmósfera proviene del sol, en forma de luz, que se transforma en calor al ser absorbido por la super• ficie terrestre. d) El aire puede ganar, entonces, energia desde la superficie y cederla hacia otras regiones más frias de la atmósfera mediante los procesos de turbulencia y advección, principalmente. Esto produce los movimientos convectivos de la atmósfera y el traslado de las masas de aire en las grandes corrientes atmosféricas. e) La precipitación se produce cuando: i) El vapor de agua se condensa. ii) Se desencadena el mecanismo de la coalescencia, que conduce a la formación de las grandes gotas de lluvia. Durante nuestros experimentos, se han pro• ducido variaciones en la temperatura, local y regionalmente . Así mismo hemos provocado precipitaciones apreciables. Una explicación de estos fenómenos podría ser la que sigue: En los productos químicos inductores, al ser puestos en contacto con la atmósfera húmeda es• table, se producen radicales libres por la acción cuántica, de naturaleza altamente selectiva, de los fotones de la luz solar. Esto induce una clásica reacción de polimerización (reacción química en cadena). Una vez que el polímero ha alcanzado un peso molecular apropiado (alrededor de 1000), se forma un "sitio activo", tradicionalmente denominados centros de nucleación o gérmenes de cristalización, de tal naturaleza que hace pensar en los existentes en el seno de los catalizadores he- terogéneos. El sitio activo así formado produce la acumu, lación a su alrededor de moléculas de agua que eventualme·nte se condensan y se precipitan en forma de lluvia. Este cambio de estado, así como las reacciones ya descritas, promueve, al absorber• se o cederse energía, cambios de temperatura co• mo los observados durante los experimentos. Esta hipótesis, aunque contamos con datos que la apoyan, necesita comprobarse con mayor experimentación en el campo, así como en el laboratorio. Es plausible, entonces, provocar cam• bias en las condiciones meteorológicas, mediante la estimulación catalítica artificial, de modo que sea posible controlar los intercambios energéticos en la atmósfera, así como hasta cierto punto, la frecuencia, monto y distribución de la precipita• ción, tal como hasta ahora hemos observado en nuestros resultados experimentales. ¡:, " [ ,:¡ /~ ·-· ··'o Biól.

L. México Otoño - Invierno, 1995 EDITORIAL De acuerdo con Aristóteles la inteligencid puede desarollarse y perfeccionarse a base de hábitos. Uno de estos hábitos o virtudes es la epísteme, que se ha traducido luego como ciencia. La ciencia o hábito cientifico, es pues, dentro de esta concepción, una cuafülad intelectual y no un conjunto de conocimientos sistematizados. Así pues la ciencia y el arte en el pensamiento filosófico griego son cualidades internas de un sujeto y gracias a ello se facilitan la ciencia y el arte en sentido objetivo, tdl como se entiende enlá actualidad. Es importante traer esta conceptualización griega, pues el objeto de la bibliotecologfa, reúne todas estas acepciones, ya que el investigador siempre recurre a los materiales bibliográficos par~ Jfevar acabo sus investigaciones y nosotros como profesionales de la bibliotecologia; debemos brindarle toda la facilidad para una bflsqueda Exitosa. Sin embargo, no debemos de dejar a un lado las bases primarías de nuestro quehacer; que si bien aunado a la tecnología imperante en el mercado, brinda una gama de caminos hacia busqu d en cualquier parte del mundo, es de vital importancia no dejarlas, puesto que de ellas depende el éxito de la sistematiLación bíbliotecana que es, en la actualidad en nuestra universidad un reto y el cual debemos salvar con hito y, sobre todo con bases firmes sobre aquello que representa ordenar, catalogar y clasificar los materiales o documentos en donde se hallan impresas hipótesis, investigaciones, técnicas, etc. que servirán para brindar a nuestro mundo nuevos conceptos y acepciones sobre cualquier rama del saber.
