As atividades antrópicas têm alterado profundamente os ambientes naturais e muitas vezes afetado a diversidade e distribuição dos anuros. O objetivo deste estudo foi investigar as seguintes questões: (1) qual a composição da anurofauna em uma região de pastagem com clima marcadamente sazonal no extremo noroeste paulista? (2) como adultos e girinos das espécies se distribuem temporal e espacialmente? (3) a riqueza de espécies está correlacionada com descritores da heterogeneidade dos hábitats de reprodução? Na área estudada foram registradas 20 espécies de anuros, distribuídas em 11 gêneros de quatro famílias: Leptodactylidae (9), Hylidae (8), Microhylidae (2) e Bufonidae (1). Destas, Chaunus schneideri (Werner, 1894), Physalaemus centralis Bokermann, 1962 e Physalaemus fuscomaculatus (Steindachner, 1864) foram registradas apenas por coleta de girinos, enquanto Dendropsophus minutus (Peters, 1872) e Leptodactylus labyrinthicus (Spix, 1824) ocorreram somente em corpos d'água próximos aos selecionados. As espécies registradas são conhecidas por sua ampla distribuição geográfica e por colonizarem áreas alteradas em outras localidades. Não houve correlação entre a riqueza de espécies e a complexidade estrutural dos corpos d'água. Entretanto, a maior riqueza de espécies foi registrada nos corpos d'água de longa duração. As poças temporárias de hidroperíodo instável foram colonizadas inicialmente por leptodactilídeos, enquanto que as poças permanentes ou temporárias estáveis foram colonizadas por hilídeos. A atividade de vocalização e de reprodução da maioria das espécies foi restrita ao período quente e chuvoso do ano, um padrão típico de ambientes tropicais sazonais. Cinco espécies [Chaunus schneideri, Dendropsophus nanus (Boulenger, 1889), Hypsiboas albopunctatus Spix, 1824, Leptodactylus podicipinus (Cope, 1862) e Pseudopaludicola aff. saltica (Cope, 1887)] vocalizaram durante a estação seca e chuvosa, mas apenas C. schneideri e H. albopunctatus se reproduziram durante o período seco. A fraca partilha espacial e temporal, registrada para adultos e girinos, não foi suficiente para explicar o isolamento reprodutivo entre as espécies. Outros fatores, como a partilha acústica e a segregação dos sítios de vocalização, podem ter maior importância para explicar a coexistência das espécies. A severidade climática (extensa e pronunciada estação seca, imprevisibilidade e inconstância das chuvas no início da estação chuvosa), juntamente com o elevado grau de conversão do hábitat natural em áreas de cultivo são, provavelmente, os fatores responsáveis pelo predomínio de espécies conhecidas por colonizar com sucesso áreas antrópicas em outras regiões do país.Anthropic activities have deeply changed natural environments and constantly affected the diversity and distribution of anurans. This study aimed to investigate the following questions: (1) What is the frogs composition in a pasture region with a pronounced seasonal climate in extreme northwest of the state of São Paulo? (2) How are adults and tadpoles of the species distributed temporally and spatially? (3) Is species richness correlated to descriptors of reproductive habitats heterogeneity? In the study site 20 anuran species were recorded, distributed in 11 genus of four families: Leptodactylidae (9), Hylidae (8), Microhylidae (2) and Bufonidae (1). From these, Chaunus schneideri (Werner, 1894), Physalaemus centralis Bokermann, 1962 and Physalaemus fuscomaculatus (Steindachner, 1864) were recorded only by tadpoles collection, whereas Dendropsophus minutus (Peters, 1872) and Leptodactylus labyrinthicus (Spix, 1824) occurred only in water bodies next to the studied ones. The recorded species are known by their ample geographic distribution and for colonizing disturbed areas in other localities. There was no correlation between species richness and structural complexity of water bodies. However, the greater richness was recorded in temporary water bodies that kept water more than six months throughout the year. The temporary ponds of unstable hydroperiod were colonized initially by leptodactylids, while the permanent or temporary ponds were colonized by hylids. The vocalization and reproductive activity of most species were restricted to the warm and rainy period of the year, a typical pattern of communities in the tropical seasonal regions. Five species [Chaunus schneideri, Dendropsophus nanus (Boulenger, 1889), Hypsiboas albopunctatus Spix, 1824, Leptodactylus podicipinus (Cope, 1862) and Pseudopaludicola aff. saltica (Cope, 1887)] vocalized during the dry and rainy seasons, but only C. schneideri and H. albopunctatus reproduced during the dry season. The weak spatial and temporal segregation, recorded to adults and tadpoles, is not enough to explain reproductive isolation among species. Other factors, like acoustic segregation and calling site segregation, may have major importance to explain species coexistence. Climatic severity (wide and pronounced dry season, unpredictability and inconstancy of rains in the beginning of the rainy season), along with the high level of natural habitat being converted in cultivated areas are, probably, the factors responsible for the predominance of species typical from disturbed areas.

An account of the resource
This article focuses on the epidemiological methods and results of a global Ecohealth study that explored the complexity of the relationship between ecological, biological, economical, social and political factors and vector presence. The study was carried out in two dengue endemic areas of Colombia. A transdisciplinary team gathered quantitative and qualitative data. A survey in randomly sampled households was applied and, simultaneously, direct observation of potential breeding sites was carried out. Logistic regressions and qualitative techniques were used. Qualitative and quantitative data were compared using triangulation. The presence of low water containers increases seven-fold the risk of finding immature forms ofAedes aegypti in the household (OR = 7.5; 95%CI: 1.7-32.2). An inverse association between socioeconomic stratum and presence of the vector was identified (Low stratum OR = 0.9; 95%CI: 0.6-1.4; High stratum OR =0.4; 95%CI: 0.07-1.7). Water management is a complex social dynamic associated with the presence of Ae. aegypti. Dengue control is a challenge for public health authorities and researchers as they should address promotion and prevention strategies that take into account cultural, behavioral, socioeconomic and health factors.Este artículo se enfoca en los métodos epidemiológicos y resultados de una investigación global en Ecosalud que exploró la complejidad de la relación entre factores ecológicos, biológicos, económicos, sociales y políticos y la presencia de Aedes aegypti. El estudio se llevó acabo en dos áreas endémicas de Colombia. Un equipo transdisciplinario recogió y analizó información, tanto cualitativa como cuantitativa. Se aplicó una encuesta en una muestra de casas escogidas aleatoriamente. Simultáneamente, se realizó observación directa de criaderos potenciales. La articulación entre los datos cuantitativos y cualitativos se efectuó mediante triangulación. La presencia de tanques bajos aumentó el riesgo siete veces (OR = 7,5; IC95%: 1,7-32,2). Se identificó una asociación inversa entre el estrato socioeconómico y la presencia del vector (Estrato bajo OR = 0,9; IC95%: 0,6-1,4; Estrato alto OR = 0,4; IC95%: 0,07-1,7). El manejo del agua es una dinámica social compleja, asociada con la presencia de Ae aegypti. El control de dengue se convierte en un reto para las autoridades en salud y para los investigadores, puesto que deben desarrollarse estrategias de prevención y promoción que tengan en cuenta aspectos culturales, socioeconómicos y de comportamiento.

Description
An account of the resource
La necesidad de hacer frente a la emergencia climática y la crisis ecológica global de nuestro tiempo ha auspiciado el despliegue de enfoques transdisciplinarios en la nueva ciencia de la sostenibilidad que, consciente o inconscientemente, suponen cierta materialización tardía de los planteamientos del programa de ciencia unificada de Otto Neurath. Más allá del ámbito de la filosofía académica, Neurath está muy presente en el ámbito de la economía ecológica. Sin embargo, la ciencia de la sostenibilidad ha desarrollado poco sus propios fundamentos filosófico-metodológicos. Este texto trata de relacionar los nuevos enfoques multidisciplinarios de la ciencia de la sustentabilidad con la lógica del sentido común a la que hubiera querido dedicarse Manuel Sacristán, o con la tercera cultura que tanto interesó a Francisco Fernández Buey. Ello plantea, inevitablemente, dos preguntas básicas: ¿por qué, sabiendo de sobra de su existencia y su obra, y estando tan cerca de sus planteamientos, Manuel Sacristán habló y escribió tan poco sobre Neurath? ¿Por qué tampoco Francisco Fernández Buey estableció una conexión más explícita con la obra de Neurath y su propio programa filosófico, pese a estar presente en partes relevantes de su obra?

Existem poucos estudos sobre os solos sob cultivo de subsistência em assentamentos rurais do norte da Amazônia. Os objetivos deste trabalho foram a caracterização de solos da Colônia Agrícola do Apiaú, Roraima, e a avaliação das alterações em algumas propriedades químicas resultantes dos sistemas de manejo adotados pelos agricultores, bem como os impactos da ação de queimadas nos solos. As áreas estudadas foram: pastagens, cultivo de banana e de milho, mata queimada e não queimada. As amostras de solos foram submetidas a análises químicas e mineralógicas. Foram encontrados Latossolos, Argissolos e Gleissolos, todos possuindo mineralogia caulinítica e expressivos teores de Ti, evidenciando elevado grau de intemperismo. Os Argissolos e Gleissolos possuem baixos teores de Fe. Os baixos teores de cátions trocáveis indicam a baixa fertilidade natural, com elevada saturação por Al no complexo sortivo na maioria dos solos. A pobreza química resultou em pouca variação química entre os diferentes solos. Comparativamente, a área cultivada com banana mostrou os maiores teores de cátions trocáveis e de P disponível no horizonte superficial, conseqüência da mineralização dos restos culturais pela ação do fogo e maior proximidade de afloramentos de rocha. A pobreza química extrema nos Argissolos refletiu-se na má qualidade da pastagem degradada. Os baixos teores totais de Zn, Cu e Mg indicaram sua baixa reserva e possível deficiência.There are few studies on soils under slash-and-burn agriculture in settlements in Amazônia. The aim of this study was the soil characterization in the Apiaú Agricultural Colony, Roraima, and to evaluate changes in some soil chemical properties in function of the management systems and the impacts of burning to the soil properties. The studied areas were: pastures, cultivated with banana and maize, burned forest and natural forest. The samples were submitted to physical chemical and mineralogical analysis. The soils are highly weathered Argisols, Latosols and Gleisols, all with kaolinitic mineralogy. The Argisols and Gleisols have low iron contents and high titanium oxides contents, and are highly weathered. The low exchangeable cátions amounts determine the very low fertility, with high exchangeable aluminium saturation in the soils. The poor chemical status of the soils results in little variation between the different environments studied. The area cultivated with banana showed the highest values of exchangeable cations and available P in the surface horizon, due to organic matter mineralization after burning, and proximity to rock outcrops. The extreme chemical dystrophy in the degraded pastures is associated with abundance of weeds. The low total amounts of zinc indicate that zinc deficiency may occur, depending on which forms are present.

A cultura do repolho é cultivada em áreas pequenas e necessita de muita mão de obra, sendo na maior parte conduzida pela agricultura familiar. Avaliou-se o efeito de doses de boro em diferentes cultivares de repolho na região oeste de Mato Grosso do Sul. O experimento foi conduzido na Universidade Estadual de Mato Grosso do Sul, Unidade Universitária de Aquidauana. O delineamento experimental utilizado foi de blocos casualizados no esquema fatorial 2 x 5, sendo duas cultivares e cinco doses de boro, com quatro repetições. Foram avaliadas as características: teores de boro foliar, área da planta, altura de planta, número de folhas externas, massa fresca de folhas externas, massa seca de folhas externas, altura da cabeça, diâmetro da cabeça, número de folhas internas, massa fresca de folhas internas, massa seca de folhas externas, classificação do peso da cabeça, compacidade e produção por hectare. A cultivar 60 Dias apresentou maiores valores nos componentes de produção e conseqüentemente maior produtividade. A aplicação de boro influencia linearmente nos teor de boro foliar, diâmetro de cabeça e número de folha interna. As doses de boro interferem na produtividade de repolho, sendo que na cultivar 60 Dias a dose máxima é de 7,2 kg ha-1 e para cultivar Chato de Quintal a dose mínima deve ser de 1,06 kg ha-1.The cabbage crop is cultivated in small areas and requires much labor, this crop being mostly driven by family farmers. This study aimed to evaluate the effect of boron levels in different cultivars of cabbage in western Mato Grosso do Sul state, Brazil. The experiment was carried out at the Universidade Estadual de Mato Grosso do Sul, Unidade Universitária de Aquidauana. The experimental design was randomized blocks in factorial scheme 2 x 5, two cultivars and five doses of boron, with four replications. We evaluated the following features: boron foliar plant area, plant height, number of outer leaves, fresh weight of outer leaves, leaf content of boron, plant area, plant height, number of outer leaves, fresh weight of outer leaves, dry weight of outer leaves, classification according to head weight, compactness and yield per hectare. The cultivar 60 Dias showed higher values for yield components and consequently greater productivity. The application of boron influences linearly in the boron content of leaves, head diameter and number of inner leaves. The boron levels interfered the yield of cabbage, the maximum dose for '60 Dias' being 7.2 kg ha-1 and the minimum necessary dose for the cv. Chato de Quintal being 1.06 kg ha-1.

Los huertos caseros son una fuente de recursos genéticos, de conocimientos ancestrales y de seguridad alimentaria para la humanidad. El objetivo de este trabajo fue caracterizada la agrodiversidad de los huertos caseros en una zona de la región Andina del sur de Colombia (Ancuya, Nariño), localizado en las coordenadas 1°15`59,52”LN, 77°31`63”LO. Se muestrearon 120 predios en 13 veredas, donde se aplicaron encuestas semiestructuradas con 31 variables. La información se procesó mediante el análisis de Correspondencias Múltiples (ACM), y análisis de agrupamiento. Para el el estudio de la composición florística del huerto tipo, se utilizó la metodología del área mínima. A las especies leñosas se les determinó el diámetro a la altura del pecho (DAP) tomando especies con DAP ≥ a 10cm. Se estimaron variables ecológicas como frecuencia, dominancia, abundancia e índice de valor de importancia (IVI). Se obtuvieron cinco factores que explican el 30,39% de la variabilidad. Predomina el factor uno cuyas variables están relacionadas con la diversidad de especies presentes en los huertos caseros. Se concluye que en la composición florística del huerto tipo, se encontraron 142 especies, entre árboles, arbustos, cultivos alimenticios y medicinales pertenecientes a 126 géneros y 66 familias. La familia predominante es Lamiaceae con 10 especies.

La región sur del Ecuador posee una gran biodiversidad y zonas de conservación nacional e internacional. El objetivo de este trabajo fue evidenciar la importancia económica de los servicios ecosistémicos que brinda el humedal La Tembladera (HLT), ubicado en la provincia de El Oro. Se realizó una investigación bibliográfica abordando la Convención de Ramsar, la Evaluación de los Ecosistemas del Milenio (EM) y del Ministerio del Ambiente. Las Partes Contratantes de Ramsar promueven la conservación y uso racional de los servicios de ecosistemas de humedales (de abastecimiento, de regulación y cultural); según la EM, los servicios ecosistémicos representan gran importancia económica, donde, la valoración económica se ha convertido en un instrumento para adoptar políticas de conservación y desarrollo sostenible. El HLT proporciona los servicios descritos en Ramsar y EM, abastece de agua a la agricultura y ganadería, proporciona alimentos (pesca), regula el clima y almacena carbono, y las comunidades han recibido ayuda nacional e internacional para impulsar el turismo (servicio cultural). Por lo tanto, el HLT proporciona servicios desde la seguridad alimentaria hasta la mitigación del cambio climático que son de gran importancia económica. Con una valoración integral del humedal se podrían poner los temas de conservación y manejo en las agendas de quienes toman decisiones.

Description
An account of the resource
Este artículo recapitula de modo sintético la trayectoria de un tipo de movimiento social —que se produce como resultado del deterioro paulatino del entorno natural— y, de modo concomitante, la formación de una corriente de la disciplina —que comporta toda una renovación teórica—: la llamada sociología pragmática. En el caso de Francia, se propone entender la génesis de dicho movimiento, su desarrollo en las dos últimas décadas, las lógicas de negociación a las que ha dado lugar en medio de conflictos y controversias, y los efectos prácticos que ha producido. Así, se delinean los ejes conceptuales de la tendencia, los campos de análisis que ha ido acotando y sus figuras más representativas.

Description
An account of the resource
El melón (Cucumis melo L.) es una de las hortalizas más importantes en México, donde la ComarcaLagunera destaca como la principal región melonera. Es un cultivo atacado por diversas plagas y enfermedades quelimitan su producción, por lo que su control depende del uso plaguicidas sintéticos. Con el �n de identi�car los tiposde plaguicidas, sus formas de uso en la producción de melón en la Comarca Lagunera y analizar el per�l toxicológicode los plaguicidas más usados, se realizó un estudio descriptivo transversal durante el ciclo agrícola 2010 mediante unaencuesta en 19 predios seleccionados por muestreo dirigido en las principales áreas de producción. De acuerdo conlos resultados, se usaron 50 ingredientes activos (i.a.) de 26 grupos químicos, el 26 % de i.a., no están autorizadospara melón por la COFEPRIS y 46 % son altamente peligrosos para la salud y el ambiente según el PAN International.En todos los predios se practicó la subdosi�cación o sobredosi�cación y en 95 % se emplearon mezclas con dos a seisplaguicidas. De los siete plaguicidas más usados seis son de alto riesgo sanitario y ambiental, estos fueron carbofuran(68 %), endosulfan (58 %), clorotalonil (58 %), mancozeb (53 %), imidacloprid (47 %) y metamidofos (42 %). Estosresultados muestran la necesidad de fomentar alternativas de control �tosanitario que disminuyan el uso de plaguicidassintéticos, así como promover una regulación estricta que vigile su uso correcto y prohíba los plaguicidas altamentepeligrosos.

Description
An account of the resource
The impact of pig slurry and poultry litter fertilization on soils depends on the conditions of use and the amounts applied. This study evaluated the effect of organic fertilizers after different application periods in different areas on the physical properties and organic carbon contents of a Rhodic Kandiudox, in Concordia, Santa Catarina, in Southern Brazil. The treatments consisted of different land uses and periods of pig and poultry litter fertilization: silage maize (M7 years), silage maize (M20 years), annual ryegrass pasture (P3 years), annual ryegrass pasture (P15 years), perennial pasture (PP20 years), yerba mate tea (Mt20 years), native forest (NF), and native pasture without manure application (P0). The 0-5, 5-10 and 10-20 cm soil layers were sampled and analyzed for total organic carbon, total nitrogen and soil physical properties such as density, porosity, aggregation, degree of flocculation, and penetration resistance. The organic carbon levels in the cultivated areas treated with organic fertilizer were even lower than in native forest soil. The organic fertilizers and studied management systems reduced the flocculation degree of the clay particles, and low macroporosity was observed in some areas. Despite these changes, a good soil physical structure was maintained, e.g., soil density and resistance to penetration were below the critical limits, whereas aggregate stability was high, which is important to reduce water erosion in these areas with rugged terrain in western Santa Catarina, used for pig and poultry farming.
