1. Intra-annual variation in rainfall and it’s influence of the adult’s Cyprideis spp (Ostracoda, Crustacea) on a eutrophic estuary (Guanabara Bay, Rio de Janeiro, Brazil).
Resumo A distribuição espacial e temporal de duas espécies de ostracodes adultos (Cyprideis sp. e Cyprideis salebrosa) foi estudada em função do padrão pluviométrico na Baía de Guanabara, Rio de Janeiro, Brasil. As amostras foram coletadas em dez estações ao longo de seis campanhas, representando três períodos (Seco, Pré e Pós Chuvoso) por dois

2. Avaliação da Habilidade do Modelo WRF em Representar a Precipitação na Amazônia Usando Diferentes Escalas
Resumo A precipitação no norte da Amazônia dos verões e outonos austral, do período de 1988 a 1999, foi simulada utilizando o modelo regional Weather Research and Forecasting (WRF), através de uma abordagem em escalas distintas, com domínios aninhados de 45 e 15 km. As condições iniciais e de contorno foram obtidas da Climate Forecast System Reanaly

3. Spatiotemporal ecology of two Neotropical herbivorous mammals
Abstract On this study, we used camera traps in a Semi deciduous Seasonal Forest, northeast of Brazil, to estimate the frequencies of occurrence of two Neotropical herbivorous mammals: the spotted paca (Cuniculus paca) and the tapeti (Sylvilagus brasiliensis), analyzing their seasonal variations of spatial distribution. We also characterized the activity pat

4. Padrões espaciais de samambaias em Floresta Estacional Perenifólia na transição Amazônia-Cerrado
Resumo O clima e as condições edáficas são importantes preditores dos padrões espaciais e da diversidade alfa de espécies vegetais. A distribuição espacial das populações vegetais fornece informações sobre processos ecológicos que regem as comunidades. Nesse estudo investigamos a riqueza e os padrões espaciais intra e interespecíficos de espé

5. Large-scale migration of a school shark, Galeorhinus galeus , in the Southwestern Atlantic
ABSTRACT Knowledge of the spatial and temporal distribution patterns of chondrichthyans is critical for their effective management. In this study we report and analyze a large-scale latitudinal migration (~ 1,425 km) of a female school shark in the Southwestern Atlantic shelf where it is currently classified as Critically Endangered. During the austral summe

6. Spatial Distribution of Annual and Monthly Rainfall Erosivity in the Jaguarí River Basin
ABSTRACT The Jaguarí River Basin forms the main water supply sources for the São Paulo Metropolitan Region and other cities in the state. Since the kinetic energy of rainfall is the driving force of water erosion, the main cause of land and water degradation, we tested the hypothesis of correlation between the erosive potential of rainfall (erosivity) and

7. Partitioning of the diffuse attenuation coefficient for photosynthetically available irradiance in a deep dendritic tropical lake
ABSTRACT We studied the effects of particulate and dissolved optically active components on the attenuation of photosynthetic active radiation (PAR) in a tropical lake. The temporal and spatial distribution of tripton, Chl-a and aCDOM(440) and their relative contribution to the diffuse PAR attenuation coefficient (Kd) was investigated at 21 sites (dry and we

8. Anopheles fauna of coastal Cayenne, French Guiana: modelling and mapping of species presence using remotely sensed land cover data
Little is known about the Anopheles species of the coastal areas of French Guiana, or their spatiotemporal distribution or environmental determinants. The present study aimed to (1) document the distribution of Anopheles fauna in the coastal area around Cayenne, and (2) investigate the use of remotely sensed land cover data as proxies of Anopheles presence.

9. Effects of flooding on the spatial distribution of soil seed and spore banks of native grasslands of the Pantanal wetland
ABSTRACTTo better understand the role that flooding plays in shaping plant communities of native floodable grasslands of the Pantanal and to characterize the spatial distribution of plants, we present the results of a survey of soil seed and spore banks using the seedling emergence method. We hypothesized that terrain subjected to the deepest and longest flo

10. Diversidad, distribución espacio-temporal y turnos de vocalización de anuros (Amphibia, Anura) en un área ecotonal del nordeste de Argentina
ABSTRACT Studies on diversity and natural history of anuran communities are basic to distinguish natural fluctuations from those due to human impacts (a key tool in conservation programs), to assess the role they play in ecosystems dynamics and to allow comparison of diversity gradients. With those objectives, this paper analyzes diversity, temporal and spat

11. Population biology and distribution of the portunid crab Callinectes ornatus (Decapoda: Brachyura) in an estuary-bay complex of southern Brazil
Trawl fisheries are associated with catches of swimming crabs, which are an important economic resource for commercial as well for small-scale fisheries. This study evaluated the population biology and distribution of the swimming crab Callinectes ornatus (Ordway, 1863) in the Estuary-Bay of São Vicente, state of São Paulo, Brazil. Crabs were collected fro

12. Floristic composition and spatial distribution of vascular epiphytes in the restingas of Maracanã, Brazil
Vascular epiphytes constitute a life form that is important to maintaining the biological diversity of forest ecosystems, because they provide food resources and specialized microenvironments for fauna in the forest canopy. This study aimed to describe the floristic composition and ecological aspects of vascular epiphytes occurring in the restingas (coastal
