Title A name given to the resource Incidência de insetos fitófagos e de predadores no milho e no feijão cultivados em sistema exclusivo e consorciado Insect phitophagous and predators incidence on maize and bean cultivated in exclusive and intercropped systems Creator An entity primarily responsible for making the resource João Carlos Cardoso Galvão, Paulo Roberto Cecon, Cristina Schetino Bastos, Marcelo Coutinho Picanço, Paulo Roberto Gomes Pereira Description An account of the resource Este trabalho foi conduzido em Coimbra, MG, no ano agrícola 1996/97 e objetivou avaliar a ocorrência de insetos fitófagos e de predadores no milho e no feijoeiro cultivados em sistema exclusivo e em policultivo. Foi realizado um cultivo de milho (25/10/1996 a 24/03/1997) e dois cultivos de feijão[o primeiro de 25/10/1996 a 20/01/1997 (cultivo 'das águas') e o segundo de 25/03/1997 a 21/07/1997 (cultivo 'da seca')]. Realizaram-se contagens diretas das populações de insetos fitófagos e de predadores nas culturas. Menores densidades populacionais de herbívoros considerados preferenciais da cultura do milho [Dalbulus maidis (Delong & Wolcott) (Homoptera: Cicadellidae) e Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae)] e do feijoeiro [Diabrotica speciosa (Germ.), Cerotoma arcuata (Oliv.) (Coleoptera: Chrysomelidae) e Empoasca kraemeri (Ross & Moore) (Homoptera: Cicadellidae)] estiveram associadas ao cultivo consorciado. As densidades de herbívoros generalistas como Thrips tabaci Lind. (Thysanoptera: Thripidae) e Pseudoplusia includens (Walk.) (Lepidoptera: Noctuidae) foram maiores no feijoeiro consorciado com o milho. No cultivo 'das águas', o total de insetos fitófagos foi maior no feijoeiro consorciado com o milho do que no feijoeiro cultivado exclusivamente, sendo que o inverso ocorreu no cultivo 'da seca'. Os predadores Anthicus sp. (Coleoptera: Anthicidae) e Hymenoptera: Formicidae foram mais abundantes no milho e no feijoeiro cultivados exclusivamente do que as culturas foram consorciadas.This work was carried out in Coimbra, MG,Brazil, during the agricultural year of 1996/97 and it had the objective of evaluating the phytophagous insects and predators occurrence in maize and bean cultivated in exclusive and policultive systems. One cultivation of maize (from 10/25/1996 to 03/24/1997) and two cultivation of bean were conducted [the first one from 10/25/1996 to 01/20/1997 (rainy period cultivation) and the second one from 03/25/1997 a 07/21/1997 (drought period cultivation)]. The population of phytophagous insects and predators incident in the cultures were counted directly. Lower herbivores population density, which attacks preferentially maize [Dalbulus maidis (Delong & Wolcott) (Homoptera: Cicadellidae) and Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae)] and bean [Diabrotica speciosa (Germ.), Cerotoma arcuata (Oliv.) (Coleoptera: Chrysomelidae) and Empoasca kraemeri (Ross & Moore) (Homoptera: Cicadellidae)] were associated to the intercropped system. The generalists-insect densities as Thrips tabaci Lind. (Thysanoptera: Thripidae) and Pseudoplusia includens (Walk.) (Lepidoptera: Noctuidae) were higher in the bean intercropped with maize. The phytophagous-insect total number was higher in the bean intercropped with maize in the rainy period cultivation than in the bean cultivated exclusively. The opposite happened in the drought period cultivation. The predators Anthicus sp. (Coleoptera: Anthicidae) and Hymenoptera: Formicidae were more abundant in the maize and bean cultivated exclusively than when the cultures were cultivated intercropped.

Pretendendo dar conta deste conflito, a ecologia constituída como disciplina científica destaca-se como um campo problemático da ciência que busca integrar diversas disciplinas em torno de si. Alguns movimentos sociais, orientando-se por uma 'visão ecologizada' (ecossistêmica) de mundo, partem para denunciar os impactos ambientais oriundos, dentre outros, do modelo tecno-industrial altamente poluidor, consumidor dos recursos naturais e gerador da atual desordem global da biosfera. Esses movimentos, sendo orientados por éticas diferenciadas, reivindicam mudanças do quadro social e ambiental da sociedade atual a fim de garantir as necessidades das futuras gerações.Our modern concern over the environment brings us to the historical discussion of Scientific Rationalism, principally in contemporary western society, where the conflict between Man and the Natural World is at its greatest. In an attempt to solve this conflict, Ecology, a field of science, stands out riddled with problems, seeking to draw subjects from other fields into its own. Following an 'ecologized world view' (Ecosystemics), some social currents denounce the environmental impact of, technological and industrial models, highly pollutant and dependent on natural resources, generating the contemporary disorder in our biosphere. These movements, following different schools of thought, demand changes in society, taking into consideration the present and future state of the environment.

Title A name given to the resource Evaluación de la uniformidad del riego por goteo en condiciones de casas de cultivo en explotación Creator An entity primarily responsible for making the resource Carmen Duarte Díaz, Reinaldo Cun González, Omar Puig Estrada, Carlos Morales Gómez Description An account of the resource En Cuba existen 673 casas de cultivo de diferentes dimensiones, 12 m x 45 m y 20 m x 40 m agrupadas en 24 módulos (42 ha), distribuidos en 13 provincias, las que brindan a la población y al mercado de frontera producciones entre las 200 t·ha-1 y 300 t·ha-1 de hortalizas por año. Para las que los especialistas del Instituto de Investigaciones de Riego y Drenaje, proyectaron sistemas de riego por goteo. En la obtención de cosechas de buena calidad y altos rendimientos es imprescindible que los sistemas de riego funcionen con una elevada eficiencia. El presente trabajo se desarrolló con el objetivo de determinar la uniformidad del riego a través del cálculo del coeficiente de uniformidad (Cu) del sistema trabajando con un solo lateral y con dos laterales de gotero sobre el cantero en condiciones de producción. El estudio se realizó en el modulo de casas de cultivos 'Las Guásimas', situada en la provincia de La Habana a los 23° 00' ; 33,12' Latitud Norte y 82° 17'; 42,57' Longitud Oeste, a 92 m sobre el nivel medio del mar, Municipio Arroyo Naranjo; donde quedó demostrado que el coeficiente de uniformidad para el gasto de los emisores, clasifica en la categoría de bueno (> 80%), pero fuera del valor nominal recomendado por el fabricante (2 L·h-1) para ambas situaciones. El Cu general de los sistemas fue bueno y excelente (> 80 y > 90%). Concluimos que fue superior el coeficiente de uniformidad de los gastos y del sistema en general (incluyendo presiones), cuando se utilizó un lateral por hilera de cultivo. Los sistemas de riego en estas unidades productivas funcionan en muchos casos con presiones superiores a las calculadas por proyecto, lo que provoca que el gasto de los emisores sea superior a los diseñados por el fabricante.

Creator An entity primarily responsible for making the resource Juan Gonzalo Morales Osorio, Tiani Melissa Gómez Pulgarín, Juan Bautista López Ortiz, Rosana Pineda Tuirán, Leonardo Fabio Galindo López, Rafael Arango Isaza Description An account of the resource Resumen. El cultivo de la papa ocupa el cuarto lugar en el mundo en importancia después del arroz, trigo y maíz. La papa criolla (Solanum phureja) posee características valiosas desde el punto de vista culinario y nutricional, por su alto contenido de vitaminas, minerales, fibra y calidad de proteína. Colombia es un centro de diversidad y origen de papas criollas, lo que representa un enorme potencial de recurso genético para el fitomejoramiento. En la Universidad Nacional de Colombia se conserva el banco de germoplasma de papas criollas de Colombia. El estudio de los cariotipos es importante para entender las bases genéticas que apoyan los cruces que se realizan en los programas de mejoramiento. A pesar de la importancia de este recurso, la caracterización de los cariotipos de las accesiones no ha sido realizada completamente. En este estudio se caracterizaron dos materiales de la colección de S. phureja y tres provenientes de la F1 del cruce de un genotipo resistente y otro susceptible a la enfermedad conocida como gota de la papa. El análisis comparativo permitió identificar diferencias en la morfología celular, dos niveles de ploidía (diploide y triploide), con dos variaciones aneugénicas (hipodiploide y trisomía doble) y cuatro números cromosómicos (18, 24, 26 y 36) para los cinco genotipos evaluados.Abstract. Potato crop is forth in importance worldwide after rice, wheat, and corn. Diploid potato cv. Criolla (Solanum phureja) shows highly desired culinary and nutritional characteristics, such as vitamins, minerals, fiber and protein quality. Colombia is a diversity and origin center of diploid potatoes cv. Criolla, which represents an enormous genetic resource potential for plant breeding. At Universidad Nacional de Colombia the potato 'criollas' germplasm bank is mantained. Karyotype analysis is important for understanding genetic basis of plant breeding. Despite the importance of this resource karyotype analysis of this collection has not been completed. In this study two accesions of the S. phureja collection and three genotypes from a F1 obtained from a cross between a late blight disease resistant and a susceptible genotype were characterized. Comparative analysis allowed the identification of differences in the cellular morphology, two ploidy levels (diploid and triploid) with aneugenic variations (hypodiploidy and double trisomy), and four chromosome numbers (18, 24, 26 y 36) for the five genotypes evaluated.

Title A name given to the resource El Abono Mixto y la Enmienda Calcárea Creator An entity primarily responsible for making the resource Mejía Pedro Nel Description An account of the resource De gran importancia he encontrado tratar sobre este tema que de suyo dará a conocer a grandes rasgos la fuente de riqueza que existe en la 'Granja de Termales', en donde el Ministerio de la Economía Nacional posee en la actualidad ochocientos ejemplares ovinos (800). entre machos y hembras, correspondientes a las razas 'Merino puro' y los cruces de Merino con la oveja criolla de Boyacá y Marulanda.  La fuente de riqueza a que me refiero, es aquella del abono proporcionado por estos animales. No solamente debiera el Gobierno interesarse en el cultivo y sostenimiento del animal por su carne y lana, sino que debiera hacer un esfuerzo por obtener un sistema equitativo y económico de manufacturar el abono orgánico, y una vez sometido a los correspondientes procesos de fermentación, darle facilidad a los papicultores de la zona del páramo para que hagan utilización del producto en sus cultivos.  En la “Granja de Termales” haría el Gobierno Nacional una importante labor, de resultados muy directos, estudiando la manera de establecer un sistema práctico y económico de estercoleros en los cuales se pueda hacer una preparación del estiércol por lo menos en un lapso de 3 a 3 meses y medio. Las condiciones del suelo en su parte física y en su contenido de acidez, deja un margen de seguridad al éxito del abono en las zonas donde el cultivo de la papa prospera con perspectivas halagüeñas. La majada de oveja es acreedora a condiciones extraordinarias como fertilizante, factor que induce al pueblo francés a tener una gran predilección de su empleo en las prácticas del sistema intensivo de manejo del vegetal; la gran experiencia de este pueblo en su manejo, es el factor que lo acredita para ser considerado como uno de los mejores fertilizantes de origen orgánico.

Title A name given to the resource LA EDUCACIÓN AMBIENTAL EN EL BACHILLERATO: EL CASO DE LOS DOCENTES QUE IMPARTEN LA MATERIA DE ECOLOGÍA, PUEBLA-TLAXCALA (MÉXICO) Creator An entity primarily responsible for making the resource Adelina Espejel Rodríguez, Aurelia Flores Hernández, Isabel Castillo Ramos Description An account of the resource Los diferentes problemas que ocurren en el medio educativo han sido abordados desde diversos enfoques de análisis. Esta diversidad disciplinaria se deriva de la complejidad de situaciones estudiadas y es resultado de la dificultad en la definición de 'lo educativo' como un campo metodológico y teórico (Bertely, 2004). Una de estas situaciones complejas es la Educación Ambiental (EA), que atañe a esta investigación. El objetivo de este artículo es conocer los alcances y las limitaciones de la práctica de la EA para promover y construir una conciencia ambiental entre alumnos del Bachillerato, así como, estimular iniciativas proambientales. La aproximación metodológica adoptada es la Etnografía Institucional (EI) aplicada a la Educación Ambiental, la cual permitirá por un lado retratar la realidad lo más fidedigna posible, y por otro lado, adoptar este retrato a otras situaciones que ocurren en contextos institucionales similares. Entre los resultados encontramos que: (a) los docentes no tienen el perfil deseable para enseñar el curso de Ecología y ellos no tienen los conocimientos ambientales básicos; (b) el programa de estudios en la materia de Ecología ha sido creado de manera superficial y muy general; (c) el curso de Ecología es nominal y (d) la materia de Ecología es impartida en periodos de tiempo cortos y regida por una modalidad preferentemente teórica que práctica. En general, las limitaciones formativas de los docentes y las debilidades de los contenidos programáticos de la materia restringen abordar con interés y dimensionar la problemática ambiental. En consecuencia, se genera en el alumnado una formación sin actitudes y valores ambientales. El profesorado fracasa en su intención de lograr generar estudiantes con conciencia ambiental, propósito central de la materia de Ecología.
