1. Diet and microhabitat use by juveniles Rhinella ornata (Anura, Bufonidae) in an insular Brazilian Atlantic Rainforest area
Resumo A validação de muitas espécies de anuros é baseada em uma análise morfológica e descritiva de um pequeno número de espécimes com uma distribuição geográfica limitada. O gênero Scinax Wagler, 1830 é um grupo controverso com muitos táxons duvidosos e incertezas taxonômicas devido ao grande número de espécies crípticas. Um exemplo são

2. Habitat structure and their influence in lizard’s presence
Abstract Many species are declining due to environmental and physical changes in their habitats. Such disturbs alter the availability of micro-habitats and influences the presence of lizards, being even worse for threatened and endemic species. Glaucomastix littoralis is a teiid species restricted to four restingas areas of Brazil. The understanding about th

3. 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

4. Differences in larval emergence chronotypes for sympatric Rhagoletis brncici Frías and Rhagoletis conversa (Bréthes) (Diptera, Tephritidae)
ABSTRACT In central Chile, Rhagoletis brncici and R. conversa, can be found in sympatry, associated with the fruit of their native host plants: Solanum tomatillo and S. nigrum (Solanaceae), respectively. Third-stage larvae must emerge from its host in search of pupation sites, and during this period larvae must find an appropriate pupation microhabitat while

5. Richness, abundance and microhabitat use by Ardeidae (Aves: Pelecaniformes) during one seasonal cycle in the floodplain lakesof the lower Amazon River
ABSTRACT The Amazon floodplains become periodically submerged as result of seasonal changes in the water levels throughout the year. These changes influence the availability of microhabitats and consequently the abundance of organisms in these ecosystems. In this study we investigated 1) how changes in the water level affect the richness and abundance of ard

6. Influence of microhabitat on the richness of anuran species: a case study of different landscapes in the Atlantic Forest of southern Brazil
Abstract: Environmental heterogeneity is a factor which can help explain the higher local species richness. The objective of this study was to test if richness and composition of anurans species are related to available microhabitats and landscape type of sampled sites. We assume that a higher number of microhabitats increase environmental heterogeneity and

7. Diet, sexual dimorphism and reproduction of sympatric racers Philodryas aestiva and Philodryas patagoniensis from the coastal Brazilian Pampa
Abstract: Herein we investigated diet, sexual dimorphism and reproductive biology of two sympatric congeneric species at the coastal Brazilian Pampa, Philodryas aestiva and P. patagoniensis. Analysis of the stomach content of the scansorial Philodryas aestiva revealed that it feeds mainly on Anura and small mammals, while it occasionally consumes Insecta, Sq

8. Ecological and reproductive aspects of Aparasphenodon brunoi (Anura: Hylidae) in an ombrophilous forest area of the Atlantic Rainforest Biome, Brazil
ABSTRACT Presented is the first information on the ecological and reproductive aspects of the treefrog, Aparasphenodon brunoi Miranda-Ribeiro, 1920, living in ombrophilous forest areas of the Atlantic Rainforest, Brazil. We recorded the species’ daily activity and over the course of a year, population density during the year, microhabitat usage, diet, and

9. Resource use by two electric fishes (Gymnotiformes) of the National Forest Saracá-Taquera, Oriximiná, Pará
RESUMO Peixes da ordem Gymnotiformes apresentam alta diversidade morfológica, o que sugere a existência de especializações tróficas dentro dos clados. O objetivo deste estudo foi analisar o uso de recursos por duas espécies de peixes elétricos (Gymnorhamphichthys rondoni e Gymnotus coropinae) na Floresta Nacional Saracá-Taquera, Oriximiná - Pará, a

10. Relaciones espaciales y alimenticias del ensamblaje de reptiles del complejo cenagoso de Zapatosa, departamento del Cesar (Colombia)
To find environmental factors that favors richness and abundance of species and groups of reptiles, his preference for microhabitats, species diet and differences between habitats in parameters such as size of individuals, level of detection and proportion of predation, we made four field trip in surrounding areas of the Zapatosa's wetland complex, between N

11. Patterns of arboreal and terrestrial space use by non-volant small mammals in an Araucaria forest of southern Brazil
Apesar dos avanços nas técnicas para pesquisa de pequenos mamíferos arborícolas, dados ecológicos detalhados, tal como padrões de uso do habitat, são praticamente inexistentes para muitas espécies. Utilizando 150 armadilhas de captura viva instaladas no solo, sub-bosque (1,0-5,0m) e dossel (> 5,0m) nós investigamos padrões no uso do espaço arbóre

12. Habitat use by Astyanax taeniatus (Jenyns, 1842) (Characiformes: Characidae) in a coastal stream from Southeast Brazil
O uso do micro-habitat por Astyanax taeniatus de riacho do estado do Rio de Janeiro foi investigado. Realizamos 12 h de observações subaquáticas em um trecho de 200 m do alto rio Roncador e quantificamos os seguintes descritores do micro-habitat: (i) velocidade da água, (ii) distância da margem, (iii) substrato, e (iv) profundidade da coluna d'água.
