An account of the resource
No presente estudo foi analisado a dieta de Enyalius perditus Jackson, 1978 e suas variações de acordo com disponibilidade de alimento no Parque Estadual do Ibitipoca, Minas Gerais, Brasil. Três áreas de matas foram amostradas, utilizando-se armadilhas de queda e adesivas para captura dos lagartos e itens-presa disponíveis. Os lagartos (n= 55) foram dissecados e o conteúdo estomacal analisado. O Índice de eletividade mostrou que larvas foram importantes volumetricamente na dieta de E. perditus, enquanto que formigas e isópodos foram importantes numericamente. A quantidade de itens nas dietas de machos e fêmeas diferiram estatisticamente, talvez como uma conseqüência da maior quantidade de formigas ingeridas pelas fêmeas e isópodos e larvas pelos machos. Baseado no comportamento alimentar, os machos são mais semelhantes aos forrageadores ativos e as fêmeas, aos predadores senta-e-espera.The present study was carried out to describe the diet, and its variations according to food availability, in Enyalius perditus Jackson, 1978 from Parque Estadual do Ibitipoca, State of Minas Gerais, Brazil. Three areas were chosen in the forest fragments; pit falls and glue traps were used to capture lizards and their preys. Lizards (n=55) were dissected in order to analyze the stomach content. The Electivity Index showed that insect larvae were volumetrically important in the diet of E. perditus, while ants and woodlices where numerically important. The quantity of diet items have differed significantly between males and females, perhaps, as a consequence of the higher quantity of ants ingested by female lizards and larvae ingested by males lizards. Based upon alimentary behavior, the male lizards resemble the active forragers and the females sit and wait forragers.

Description
An account of the resource
En el Área Metropolitana de Concepción (AMC) persisten modos de vida y prácticas que mezclan lo urbano y lo rural asociadas al desarrollo de agricultura de pequeña escala y base socio económica familiar. Esto ha implicado la existencia de sectores rururbanos centrados en el cultivo de especies vegetales alimenticias, principalmente hortalizas. Sin embargo, estos territorios y las comunidades que en ellos desarrollan estas actividades, se encuentran fuertemente tensionados por el modelo de desarrollo urbano desplegado en las últimas décadas. Desde esta premisa, se plantea la pregunta si estas prácticas agrícolas pueden ser consideradas agroecológicas, desde el sustento conceptual de la agroecología y sus enfoques hacia formas de vida urbana más sostenibles. Para responder la pregunta, el artículo revisa algunos casos de comunidades que desarrollan agricultura en el AMC, con el objetivo de contribuir a su valorización como actividad sostenible, considerando sus aportes al sistema urbano metropolitano desde las dimensiones social, ambiental y económica. La metodología se basa en revisión de antecedentes previos sobre zonas con producción agrícola, levantamientos en terreno para conocer de primera fuente cómo se desarrollan estas prácticas, aplicación de entrevistas semiestructuradas, construcción de planimetría especializada, y discusión de las potencialidades de estas zonas como áreas de interés para la sostenibilidad urbana. Los resultados permitieron identificar zonas en cuatro comunas, y la elaboración de un marco de indicadores de evaluación de las prácticas agrícolas desde el enfoque de la agroecología. En el proceso de investigación se generaron vínculos con las comunidades, y aportes a la vinculación entre los agricultores y espacios de comercialización de sus productos en el sistema urbano. Junto con ello, se generó un archivo multimedia que permitió la elaboración de material docente para enseñanza y divulgación de estas prácticas a nivel académico y comunitario.

Description
An account of the resource
El estado de Michoacán se caracteriza por presentar una importante heterogeneidad ambiental, en términos de clima, topografía y tipos de vegetación, que incluyen al bosque tropical seco que se encuentra en peligro de extinción a nivel mundial. Algunos trabajos mencionan la presencia de las seis especies de felinos que habitan en México, para la región; sin embargo, la evidencia para apoyar estos trabajos es escasa, por lo que llenar esta falta de información es especialmente crítico en el caso de especies o hábitats amenazados. El objetivo de este estudio fue sistematizar la información y analizar los patrones de distribución de los felinos en el estado de Michoacán, dentro del centro-occidente de México. Realizamos una revisión de la información bibliográfica y contenida en bases de datos sobre la presencia de felinos en esta región. Asimismo, realizamos trabajo de campo que en el curso de diez años donde se aplicaron distintos métodos para detectar la presencia de especies de felinos (recorrido de senderos para obtener evidencia directa e indirecta de la presencia de las especies, trampas cámara y entrevistas). Localizamos 29 registros de presencia en literatura y bases de datos. Por otra parte acumulamos un total de 1 107.5 km de transectos recorridos y 8 699 días/cámara-trampa. A través de este esfuerzo de muestreo, generamos 672 registros de presencia de las seis especies. Lynx rufusfue la especie con menos registros totales (n = 3) y cuya distribución contrastó más con la del resto de las especies. La especie con más registros fue Leopardus pardalis(n = 343). En general, el 89% de los registros de felinos se obtuvieron por debajo de los 1 000 msnm. En promedio, la temperatura media anual y la precipitación anual donde se ubicaron los registros fue de 24 °C y 1 040 mm respectivamente. La especie que mostro un patrón más claro en términos de temperatura y precipitación fue L. rufus(15.8 ± 1.3°C y 941 ± 171 mm). De acuerdo con el dendrograma resultante del análisis de conglomerados de las combinaciones de ecorregiones y tipos de vegetación se logró distinguir cinco grupos. Este estudio permite tener un panorama más completo de los patrones de distribución de los felinos en una región de importante contraste ambiental y sujeto a un fuerte impacto por las actividades humanas. Asimismo, los datos generados en este estudio pueden ayudar a profundizar nuestro entendimiento de la relación que existe entre la distribución de especies de felinos y las características del ambiente y servir como base para el desarrollo de estrategias de conservación local y regional.

Description
An account of the resource
La herbivoría en aves es una estrategia poco común. Solo el 3% de las aves actuales consumen plantas como fuente de energía. Tanto la composición química de las plantas como las restricciones asociadas al vuelo y digestión en aves pueden explicar el reducido número de pequeños endotermos, como las aves, que son herbívoros. Nuestro objetivo es explicar como las aves herbívoras satisfacen sus requerimientos nutricionales y energéticos cuando consumen dietas extremadamente pobres. Para lo cual nos centramos en Phytotoma rara (Phytotomidae), posiblemente el ave herbívora más pequeña. Phytotoma rara presenta numerosas características, como el rápido tiempo de transito, un efectivo rompimiento de la pared celular, y la alta y constante actividad de las enzimas digestivas, que le permiten disponer de nutrientes y energía celulares, sin los costos energéticos asociados al desarrollo de estructuras anatómicas de fermentación bacteriana o lentos tiempos de transito. Estos son posiblemente adaptaciones cruciales en la evolución de la herbivoría en aves pequeñas.Herbivory is a rare strategy in birds. Only 3% of extant birds exploit plant material as an energy source. Both plant chemical composition and bird constraints associated to flight and digestion may explain why herbivory is so scarce in small endotherms such as birds. Here we tackle the question of how herbivorous birds meet energy/nutrient requirements when feeding on extremely poor diets. We focus on Phytotoma rara (Phytotomidae), possibly the smallest herbivorous bird. From our mini-review we conclude that several features such as the fast passage rates, an effective physical breakdown of cell walls, and constant and high activities of digestive enzymes make available the highly nutritious cell contents to the small herbivore, without the energy costs of anatomical structures for bacterial fermentation or slow passage rates. These are possible crucial adaptations in the evolution of herbivory in small birds.

Description
An account of the resource
O tripes Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) é uma das pragas mais importantes em cultivos protegidos, principalmente de plantas ornamentais e hortícolas. Entre os problemas enfrentados pelos agricultores estão a dificuldade de seu controle com o uso de inseticidas devido à sua preferência pelas partes internas das flores e a evolução de resistência aos agroquímicos. O objetivo da pesquisa foi caracterizar a resistência de F. occidentalis a espinosade e avaliar a frequência de insetos resistentes ao inseticida, em áreas comerciais de crisântemo de diversos municípios do Estado de São Paulo. Seleções para resistência a espinosade foram realizadas em laboratório, utilizando-se uma população de F. occidentalis, coletada em 2007 de um cultivo comercial de crisântemo em Campinas (SP). No decorrer de sete seleções para resistência, a CL50 de espinosade passou de 8,41 mg i.a. L-1 para 1111 mg i.a. L-1. Comparando-se a linhagem resistente (R) (selecionada) e a suscetível (S), a razão de resistência (CL50 R/CL50 S) atingiu valores de ≈280 vezes. Estabeleceu-se uma concentração discriminatória de 98 mg i.a. L-1 para o monitoramento da resistência de F. occidentalis a espinosade. O monitoramento foi realizado coletando-se 19 populações do tripes em áreas comerciais de crisântemo no Estado de São Paulo. Os bioensaios foram realizados com ninfas de segundo ínstar de F. occidentalis, colocadas em arenas de folha de feijão. As aplicações de espinosade, na sua concentração discriminatória, foram realizadas sobre as ninfas em torre de Potter. Os resultados indicaram alta variabilidade entre as populações com relação à suscetibilidade a espinosade. Foram observadas populações com até 40,7% de insetos resistentes. Este é o primeiro relato de resistência de F. occidentalis a espinosade no Brasil.

Description
An account of the resource
Tras el éxodo rural masivo que marcó las décadas de los años cincuenta a los setenta, elabandono del medio rural ha continuado, con menor intensidad, aunque con una participaciónfemenina cada vez más dominante. Este abandono de las áreas rurales, junto con los cambios enlas pautas de comportamiento demográficas y sociales de las mujeres rurales en las dos últimasdécadas del siglo XX, podría comprometer el desarrollo sostenible del medio rural granadino,tan necesario para frenar la despoblación que viene sufriendo desde mediados del siglo pasado.Este artículo se centra en el análisis de las variables sociodemográficas que permiten conocertanto las oportunidades como las limitaciones que enfrentan las mujeres rurales a comienzos delsiglo XXI, así como las opciones para que contribuyan al desarrollo de sus lugares de origen.La base territorial usada en este artículo se corresponde con las agrupaciones municipales quese han formado para acceder a las subvenciones de la iniciativa LEADER PLUS y del programaPRODER A.
