1. Use of microhabitats affects butterfly assemblages in a rural landscape
Abstract Landscapes composed of small rural properties may support highly heterogeneous habitat, because they often cover distinct types of land uses adjacent to surrounding forest fragments. Many butterfly species may benefit from this kind of landscape, as very distinct microhabitats can be found in a very restricted spatial scale. To better understand how

2. Distribution and habitat preference of Ephemeroptera and Trichoptera in subtropical mountain streams: implications for monitoring and conservation
Abstract: The assessment of biotic-habitat relationships provides key information to predict biotic responses to perturbations and important tools for river management and monitoring. This study aimed to assess the spatial distribution of Ephemeroptera and Trichoptera in mountain streams of central Argentina. We evaluated the effect of seasonality and identi

3. Habitat, limnological signatures and spatial modeling: a zoning proposal for the Curuá-Una hydroelectric reservoir, Pará, Brazil
Resumo Objetivo O objetivo deste trabalho é caracterizar, modelar espacialmente e realizar o zoneamento do ambiente aquático no reservatório da UHE de Curuá-Una, no estado do Pará, na Amazônia brasileira. Métodos Os dados foram coletados em 77 pontos amostrais distribuídos em 20 transectos no reservatório de Curuá-Una, no mês de novembro de 20

4. Wild pig (Sus scrofa L.) occupancy patterns in the Brazilian Atlantic forest
Resumo: Apesar dos grandes impactos da invasão do javali (Sus scrofa) nos ecossistemas naturais, o uso de hábitats por esta espécie nos neotrópicos ainda permanece pouco estudado. Aqui, nós investigamos os efeitos do hábitat local e de covariáveis da paisagem (tipos de vegetação, cursos d'água e estradas) sobre os padrões de ocupação do javali n

5. Distribution of gall-inducing arthropods in areas of deciduous seasonal forest of Parque da Sapucaia (Montes Claros, MG, Brazil): effects of anthropization, vegetation structure and seasonality
Abstract In the present study, we inventoried gall-inducing arthropod species and evaluated the effects of habitat anthropization, vegetation structure and seasonality on this group in areas of deciduous seasonal forest of Parque da Sapucaia, Montes Claros, MG, Brazil. The gall-inducing fauna was sampled between April 2017 and February 2018 from 20 plots dis

6. Metrics of benthic communities and habitat quality associated to different types of land use
RESUMO Os ecossistemas aquáticos estão sob fortes modificações antrópicas. Assim, comunidades biológicas dependentes desses ambientes também são alteradas. O objetivo deste estudo foi investigar os efeitos do desenvolvimento urbano em um ecossistema impactado. Foram selecionadas 15 seções de amostragem ao longo do Ribeirão Vermelho e em cada uma f

7. Anuran diversity in urban and rural zones of the Itacoatiara municipality, central Amazonia, Brazil
RESUMO Poucos estudos avaliaram a diversidade de anuros em fragmentos florestais urbanos ou em áreas com diferentes graus de impacto antrópico na Amazônia. Neste estudo foi determinada a composição e abundância de anuros em áreas urbanas e rurais no município de Itacoatiara, na Amazônia central, Brasil. Anuros foram amostrados entre janeiro de 2012

8. Distribution, diversity, and habitat partitioning of Scolecitrichidae species (Copepoda: Calanoida) down to 1,200 m in the Southwestern Atlantic Ocean
In this study, we analyzed the main distributional features of Scolecitrichidae species in the Southwestern Atlantic Ocean (northern region of Rio de Janeiro State) and determined and described their habitat partitioning, based on a night series of stratified samplings down to a depth of 1,200 m. A total of 18 species from seven genera were identified and gr

9. Richness and large-scale distribution of marine benthic caridean shrimps (Decapoda: Caridea) from the Eastern Tropical Pacific
Abstract Based on an updated checklist of the benthic caridean shrimp fauna of the Eastern Tropical Pacific (ETP), we analyzed their large-scale species richness distribution patterns using a grid approximation. Caridean fauna is composed of 183 species belonging to 67 genera and 18 families. Alpheidae, Palaemonidae and Thoridae contributed largely to specie

10. Abiotic effects on the cover and richness of corticolous lichens on Araucaria angustifolia trunks
ABSTRACT Lichens play a key role in natural ecosystems, as they can function as primary producers, recycle minerals and fix nitrogen. Despite their environmental importance, little is known about lichen ecology in Brazil, and especially about how abiotic factors may influence their spatial distribution. In this study, we aimed to verify how the cover and ric

11. Community structure and population dynamics of small mammals in an urban-sylvatic interface area in Rio de Janeiro, Brazil
ABSTRACT The Atlantic Forest is one of the most disturbed Brazilian biomes, with 183 out of 298 species of mammals occurring in the state of Rio de Janeiro. In this study, we aimed to characterize the diversity, community structure, and habitat use of small mammals in the FIOCRUZ Atlantic Forest Campus (CFMA), including areas of Pedra Branca State Park (PBSP

12. Phenology of Promestosoma boggianii (Diplopoda: Polydesmida: Paradoxosomatidae) in a Neotropical floodplain
ABSTRACT Studies that address biodiversity and its supporting mechanisms in different ecosystems are fundamental to understanding the relationships between species and the prevailing environmental conditions within each habitat type. This study presents information on the phenology of Promestosoma boggianii (Silvestri, 1898) and its association with seasonal
