“…In fact, this two last species were indicator of grassland. These species are considered abundant along their geographic distribution and are very plastic in habitat use: being found in grasslands, wetland, dunes, forest, growing areas of soybean and rice, and urban areas (Peltzer et al 2003, Attademo et al 2005, Loebmann and Vieira 2005, Lucas and Fortes 2008.…”

Considering that habitat use by amphibians is related both with climate and environmental features, we tested the hypothesis that anuran assemblages found in different phytophysiognomies and in different seasons vary in structure. Additionally, we searched for species which can be indicators of habitat and seasons. The study was conducted in the Pampa biome, southern Brazil. Sampling was done through pitfall traps placed in three phytophysiognomies: grassland, ecotone grassland/forest; and forest. The seasonality factor was created by grouping months in warn and cold seasons. Sixteen species were found and the assemblages were influenced both by phytophysiognomies and climatic seasonality. In a paired comparison, the three phytophysiognomies differed in structure of assemblage from each other. Physalaemus henselii, P. riograndensis, Pseudopaludicola falcipes and Pseudis minuta were indicators of ecotone. Leptodactylus gracilis and Physalaemus biligonigerus were indicators of grassland. None species was indicator of forest. Most of the species were indicators of warm season: Elachistocleis bicolor, Leptodactylus fuscus, L. gracilis, L. latinasus, L. latrans, L. mystacinus, Physalaemus biligonigerus, P. cuvieri and Pseudis minuta. None species was indicator of cold season. We found that even for species of open areas, as Pampa, heterogeneous phytophysiognomies are important for maintaining abundance and constancy of populations of anuran.

“…BERNARDE (2007) registrou os ambientes de reprodução e a temporada de vocalização das espécies de anuros em uma localidade em Espigão do Oeste. No Brasil, existem poucos estudos sobre a anurofauna de serapilheira que utilizaram armadilhas de interceptação e queda para amostragem (ver CECHIN & MARTINS, 2000;ROCHA et al, 2004;LOEBMANN & VIEIRA, 2005;BRASILEIRO et al, 2005). Neste trabalho, estudou-se a riqueza e diversidade de anfíbios anuros em áreas de floresta e de pastagem em Rondônia e analisou-se a eficiência da utilização de armadilhas de interceptação e queda (pitfall traps with drift fences) na amostragem.…”

ABSTRACT. The impact of deforestation and pastures on the leaf-litter frog community in Rondônia, Brazil. Abundance and diversity of leaf-litter frog species were studied in forest and pasture in Rondonia, Brazil. Also, the efficiency of use of pitfall traps was examined. Pitfall traps were established in three treatments: forest interior far (> 100 m) from water; forest interior near (< 100 m) water; pasture, far from water. Species richness was typical of the Amazon region, with a total of 1,324 individuals of 27 species in nine families: Aromobatidae (1 species), Brachycephalidae (2), Bufonidae (4), Cycloramphidae (1), Dendrobatidae (1), Hylidae (5), Leiuperidae (1), Leptodactylidae (7) e Microhylidae (5). Pitfall traps captured 57% of the species known for this location, capturing mainly terrestrial and fossorial species. The greatest richness and diversity of captures were during the rainy season in the forested sites. Forest converted to pasture affects several features of the habitat that reduce habitat quality with respect to these amphibians, including fewer places for reproduction, reduced food supply, loss of leaf-litter and soil compaction all with their influence on microclimate, as well as the arrival of other species more common in open areas.

We studied the herpetofaunal community from the Atlantic forest of Morro São João, in Rio de Janeiro State, Brazil, and present data on species composition, richness, relative abundance and densities. We combined three sampling methods: plot sampling, visual encounter surveys and pit-fall traps. We recorded sixteen species of amphibians and nine of reptiles. The estimated densities (based on results of plot sampling) were 4.5 ind/100 m 2 for amphibians and 0.8 ind/100 m 2 for lizards, and the overall density (amphibians and lizards) was 5.3 ind/100 m 2 . For amphibians, Eleutherodactylus and Scinax were the most speciose genera with three species each, and Eleutherodactylus binotatus was the most abundant species (mean density of 3.0 frogs/100 m 2 ). The reptile community of Morro São João was dominated by species of the families Gekkonidae and Gymnophtalmidae (Lacertilia) and Colubridae (Serpentes). The gymnophtalmid lizard Leposoma scincoides was the most abundant reptile species (mean density of 0.3 ind/100 m 2 ). We compare densities obtained in our study data with those of other studied rainforest sites in various tropical regions of the world.
