An account of the resource
O represamento do Rio Pananá para construção da hidrelétrica de Porto Primavera, entre os Estados do Mato Grosso do Sul e São Paulo, alterou as relações ecológicas na região. O objetivo do estudo foi descrever a fauna de culicídeos potencialmente vetores nesse reservatório, a 2km da margem direita, em Bataguassu, Mato Grosso do Sul, na fase anterior à inundação. Os culicídeos foram capturados em ambientes distintos mensalmente, de julho de 1997 a novembro de 1999. Foram calculados índices de riqueza e abundância. Obtiveram-se 16.553 exemplares adultos e 1.795 imaturos, com riqueza de 86 e 44 espécies, respectivamente. A fauna culicídea da área de estudo apresentava relativa riqueza, com espécies de valor epidemiológico, como o Anopheles darlingi, além de outras com potencial na veiculação de arbovírus.The damming of Paraná River for the construction of Porto Primavera Hydroelectric Power Plant, between the states of Mato Grosso do Sul, Midwestern Brazil and São Paulo, Southeastern Brazil, has changed the ecological relationships in the area. The objective of the study was to describe the fauna that can be potential vectors in this reservoir, 2 km away from its right bank, in Bataguassu, Mato Grosso do Sul, before flooding. Mosquitoes were monthly captured in different environments from July 1997 to November 1999. During this period 16,553 adult specimens and 1,795 immature forms were collected with richness of 86 different species of adults and 44 different species of immature forms. The fauna presented a richness that included species of epidemiological importance, as Anopheles darlingi and other mosquitoes with potential for arbovirus transmission.

OBJETIVO: Identificar los factores ambientales, sociales y demográficos que contribuyen a explicar las diferencias en la transmisión de dengue en Veracruz, México, durante el periodo 1995-1998 y definir las áreas de riesgo para promover un mejor control del problema. MATERIAL Y MÉTODOS: Bajo un diseño ecológico se analizó una base de datos con el número de casos de dengue que se presentaron en 1 249 localidades en las 11 Jurisdicciones Sanitarias del estado de Veracruz durante el periodo 1995-1998. Cada una de las localidades fue identificada de acuerdo con su altitud, latitud y longitud, y con el número total de la población por sexo, el número de viviendas y la dotación de servicios públicos. Se tomó también el índice de marginación por localidad del Consejo Nacional de Población. RESULTADOS: El dengue en Veracruz se registró en 17% de las localidades y en sólo 6% de ellas se concentraron 70% de los casos de dengue en el estado. Las localidades repetidoras de dengue fueron grandes centros urbanos, con baja marginación y extensa dotación de servicios públicos. El dengue sí se transmite en las áreas rurales del estado aunque la transmisión es ocasional. El promedio de casos de dengue reportados en las localidades dependió del tamaño de la misma y del número de años que reportaron dengue durante el periodo. Se reporta un umbral poblacional para la transmisión. CONCLUSIONES: Se identificaron las localidades repetidoras de dengue que concentran 70% de los casos, y las determinantes sociales y ambientales de la transmisión. Este enfoque de riesgo puede mejorar el control y tener un impacto significativo en la prevención de la transmisión en las zonas de mayor riesgo.OBJECTIVE:To assess the ecological, social, and demographic factors associated with the transmission of dengue virus infection in Veracruz, Mexico, and to identify risk areas to target control measures. MATERIAL AND METHODS: This ecological study included data for 1,249 localities within the 11 Health Jurisdictions of the State of Veracruz, Mexico, for the 1995-1998 period. The following data were collected for each locality: total number of cases per year, population by sex, number of households, provision of public services, altitude, latitude, longitude, and deprivation index. RESULTS: Dengue transmission was registered in 17% of the localities in the State; 70% of the cases were concentrated in only 6% of the localities. Recurrent localities were urban centers with adequate availability of public services and low deprivation indices. Dengue transmission was detected in rural areas, but it was not common. The average number of cases differed according to the size of the locality and the number of years dengue was reported. A population threshold to maintain transmission was found. CONCLUSION: Recurrent localities concentrating 70% of dengue fever cases were identified, as well as the ecological and demographic factors associated with dengue transmission. The risk stratification approach to dengue transmission may improve control and prevention of this disease in high-risk areas.

Description
An account of the resource
Colombia, como primer exportador mundial de café suave, en el año 2008 produjo un promedio de 12 524 sacos de café, cada uno de 60 kg, de los cuales 3 005 toneladas corresponden a pulpa del café; estos grandes volúmenes producidos post-cosecha, son considerados contaminantes. Un uso de estos subproductos es la elaboración de abono orgánico. El proceso de compostaje tradicional tarda cerca de 150 días; por ésto se plantea disminuir el tiempo a 40 días. Se realizó el aislamiento de microorganismos a partir de un pre-enriquecimiento de la pulpa o cereza en un medio basal salino hasta obtener cultivos axénicos. Se identificaron y realizaron pruebas de compatibilidad entre cepas para seleccionar los consorcios a ensayar. Cuatro biopilas fueron elaboradas con un peso de 175 Kg cada una y una testigo. Se inocularon por aspersión con una concentración de 3 x 107 UFC/mL durante 10, 20 y 30 días, con el monitoreo de parámetros físicos. Fueron aisladas e identificadas 8 cepas: Pseudomonas aeruginosa, Citrobacter koseri, Bacillus spp., Escherichia coli, Stenotrophomona maltophilia, Cromobacterium spp., Pseudomonas spp. Las relaciones carbono-nitrógeno (C/N) en la pila 1 (9,6 %), en la pila 2 (10 %) y en la pila 4 (9,5 %), cumplieron con los valores establecidos (< 20 %), lo que demuestra madurez y calidad sanitaria con valores bajos de coliformes fecales y totales, con ausencia de Salmonella. Se obtuvo en 40 días un compost que cumple con los parámetros exigidos por la norma técnica Colombiana (NTC 5167, 2004).

Description
An account of the resource
Introducción: No se ha realizado análisis de sendero para el rendimiento, en el cultivo de melón en invernadero. Objetivo: establecer correlaciones de Pearson entre doce variables, para 10 genotipos de melón producidos bajo invernadero, y realizar el análisis de sendero para el rendimiento. Las variables fueron: edad al inicio de cosecha (días después del trasplante-ddt), peso del fruto (PF, en g), número de frutos por planta (NFP), rendimiento (kg/planta), firmeza de pulpa del fruto (N), porcentaje de sólidos solubles totales (°Brix), diámetro ecuatorial del fruto (DE, en mm), diámetro polar del fruto (DP, en mm), relación DP/DE, grosor de pulpa del fruto (GP, en mm), grosor de cavidad del fruto (GC, en mm), y relación 2GP/GC. Métodos: El cultivo se manejó con fertirrigación, en sustrato de fibra de coco. Resultados: Se obtuvo una correlación positiva y altamente significativa entre el rendimiento y: NFP (r=0,97**), relación DP/DE (r=0,65**) y DP (r=0,45**). El principal efecto directo positivo sobre el rendimiento fue ejercido por NFP (coeficiente de sendero-CS=1,05), seguido por PF (CS=0,20), DP (CS=0,16), relación 2GP/GC (CS=0,11), y GC (CS=0,06), mientras que los máximos efectos indirectos positivos sobre el rendimiento fueron ejercidos por relación DP/DE (CS=0,69) y DP (CS=0,48) a través de NFP. Por otra parte, las siguientes variables ejercieron un efecto directo negativo sobre el rendimiento: relación DP/DE (CS=-0,19), GP (CS=-0,15), y DE (CS=-0,05). Los resultados obtenidos de la correlación y el análisis de sendero mostraron que la eficiencia en la selección para rendimiento en melón puede ser aumentada a través de la selección de NFP. Conclusiones: NFP fue la variable principal que contribuyó con el rendimiento, y es un criterio de selección fundamental en fitomejoramiento de melón cultivado bajo invernadero.

¿Blanco, negro o escala de grises? Determinación de la contribución relativa del nicho ecológico y la teoría neutral en los ensambles de especies
Creator

Juan Alberti, Pedro Daleo, Oscar Iribarne
Description
An account of the resource
Según la teoría del nicho ecológico, la composición de especies en un lugar dado debería estar determinada por la conjunción de los factores bióticos y abióticos que allí actúan. En cambio, la teoría neutral propone que las especies son equivalentes y que la composición de ensambles locales está dada, entonces, por procesos de colonización y extinción independientes de las especies. Hoy en día se sabe que es difícil encontrar en la naturaleza ensambles puramente neutrales o puramente basados en el nicho ecológico, sino que lo que priman son ensambles intermedios. Los ensambles con una impronta fuerte del nicho ecológico están muy influidos por las interacciones interespecíficas o por los forzantes ambientales, mientras que los ensambles neutrales están más influidos por la deriva ecológica o por las dinámicas de extinción y colonización en base a las abundancias de las especies. El concepto de beta diversidad se tornó especialmente popular durante la última década y ha sido utilizado con diferentes finalidades en una gran variedad de ambientes. En particular, ganó mucha relevancia como herramienta para estimar la importancia relativa del nicho ecológico en los ensambles de especies. Esto se puede evaluar de forma sencilla con el uso de modelos neutrales ad hoc. En un ensamble puramente neutral, la variabilidad en la composición del ensamble entre muestras no debería ser diferente a la esperada como producto de una selección de especies al azar del total regional de especies (diversidad gama) para cada muestra (diversidad alfa). Cuanto más se aleje la variabilidad a la esperable por azar, mayor será la importancia relativa del nicho ecológico. Recientemente, hubo un gran avance en entender qué tipos de factores promueven uno u otro ensamble. Sin embargo, al ser un campo relativamente nuevo queda aún mucho por saber (e.g., interacción de factores, relación tiempoespacio, diferencias entre niveles tróficos). En este trabajo revisamos los alcances y la metodología de una temática que está viviendo un desarrollo marcado dentro de la ecología de comunidades, y discutimos algunos de los aspectos relevantes y relacionados que, por el momento, no fueron estudiados.

O objetivo com este experimento foi comparar o cultivo do tomateiro em monocultivo e policultivo (consórcio com coentro, cravo-de-defunto e o sorgo como cultura circundante) no sistema de produção orgânico, em relação à incidência de pragas, rendimento e qualidade de frutos. Foram avaliados a incidência de tripes, plantas e frutos com sintomas de virose (%), frutos broqueados por Neoleucinodes elegantalis (%), a produtividade total e comercial, o número total e comercial de frutos, o peso médio e o diâmetro dos frutos comercializáveis, o teor de sólidos solúveis totais (SST), o teor de acidez total titulável (ATT) e a relação SST/ATT. No policultivo ocorreu menor número de tripes e, consequentemente, menor percentagem de plantas e frutos com sintomas da virose. A incidência de broqueamento de frutos por N. elegantalis também foi menor em policultivo. A produtividade total e o número total de frutos no monocultivo foram superiores à do policultivo. Porém, a produtividade comercial foi igual nos dois sistemas de cultivo. O diâmetro dos frutos não diferiu entre os tratamentos, mas o peso médio dos frutos oriundos do monocultivo foi maior. Os frutos do policultivo apresentaram maiores teores de SST e ATT e a relação SST/ATT não diferiu entre os tratamentos. Assim, reforça-se a importância da diversidade vegetal no manejo de pragas, sendo necessários novos estudos que permitam definir melhor arranjo espacial das plantas para manter sua atuação na regulação de insetos-praga e qualidade dos frutos sem interferir na produtividade do tomateiro.The tomato crop in monoculture and polyculture (intercropping with coriander and marigold and sorghum as surrounding crop) were compared in organic system of production, in relation to incidence of pests, yield and quality of fruits. We evaluated the incidence of thrips, the plants and fruits with symptoms of viral disease (%), damaged fruits by Neoleucinodes elegantalis (%), total and commercial yield, total number of fruits, number of marketable fruits, fruit average weight, fruit diameter, total soluble solids (TSS) content, total titratable acidity (TTA) and relation TSS/TTA. In polyculture, a lower incidence of thrips was noticed and, consequently, a lower percentage of plants and fruits with symptoms of viral disease was recorded. The incidence of drilling by N. elegantalis was also lower in the tomatoes in polyculture. The total yield and the total number of fruits in monoculture was higher than in the polyculture. However, the marketable yield was similar in both crop systems and the number of marketable fruits was higher in polyculture. The fruit diameter was not different between treatments, but the total fruit average weight from the monoculture was higher. The fruits of polyculture showed higher content of TSS and TTA and the relation TSS/TTA did not differ between treatments. Thus, it reinforces the importance of plant diversity in pest management, requiring new studies to define a better spatial arrangement of plants to maintain its performance in the regulation of insect pests without interferring on the yield of tomato crop.
