Differential success in sampling of Atlantic Forest amphibians among different ...
Rocha,CFD.; Siqueira,CC.; Ariani,CV.; Vrcibradic,D.; Guedes,DM.; Kiefer,MC.; Almeida-Gomes,M.; Goyannes-Araújo,P.; Borges-Júnior,VNT.; Van Sluys,M.In general, anurans tend to be nocturnal, though diurnal activity is characteristic of some groups. Studies show that frog activity may be inferred based on the number of individuals collected at different periods of the day, during large-scale field surveys. We investigated the best period of the day to conduct amphibian sampling in nine Atlantic Rainforest areas in southeastern Brazil, based on intensive fiel...

A potential recovery of a population of the sand lizard Liolaemus lutzae Merten...
Rocha,CFD.; Siqueira,CC.; Ariani,CV.The endemic and threatened lizard Liolaemus lutzae has a relatively small geographic range restricted to only 200 km of along the coast of Rio de Janeiro State, Brazil, which are habitats under intensive anthropic disturbance. At the Barra da Tijuca beach, in Rio de Janeiro city an estimate of the population abundance made in 1991, compared to a previous estimate made in 1984, showed a considerable decrease (ab...
Feeding ecology of the lizard Tropidurus oreadicus Rodrigues 1987 (Tropiduridae...
Rocha,CFD.; Siqueira,CC.Tropidurus species commonly prey on arthropods, but they may also feed on vertebrates and plant material. The lizard Tropidurus oreadicus (Tropiduridae) is common in open vegetation habitats and generally has sexual dimorphism. In this study we analyzed the diet of T. oreadicus at Serra dos Carajás, Pará, in the north of Brazil. Snout-vent length (SVL) and jaw width (JW) were taken for 34 lizards. There was a s...
