Anurans of the Estacao Ecologica de Santa Barbara, a remnant of open Cerrado formations in the state of Sao Paulo

Although São Paulo is the state with the most knowledge about anurans from Brazil, it still has important knowledge gaps about this group especially in the remnants of the Cerrado Biome. Only 0.5% of this biome is protected by conservation units in the state and remaining fragments suffer threats that include isolation, risk of fire and invasion by exotic plant species. The aim of this study was to obtain information on anurans species recorded at Estação Ecológica de Santa Bárbara, one of the few remnants in Middle Paranapanema river basin that has a predominance of open Cerrado formations. The inventory was conducted monthly from October/2008 to March/2009, totaling 30 sampling days. Surveys were conducted using pitfall traps with drift fences, incidental encounters and acoustic and visual searches. We recorded 33 anuran species, belonging to 14 genera and six families (Bufonidae, Cycloramphidae, Hylidae, Leiuperidae, Leptodactylidae e Microhylidae). Although species richness was not different between open and forest vegetation types, there was a greater abundance of anurans in the open formations, reflecting the largest association of individuals to water bodies present in open phytophysiognomies during the reproductive period. This research is an important contribution to expanding the knowledge about anurans species in the Cerrado, one of the priority global hotspots for biodiversity conservation.Although São Paulo is the state with the most knowledge about anurans from Brazil, it still has important knowledge gaps about this group especially in the remnants of the Cerrado Biome.

Composition, species richness and abundance of amphibians and reptiles in the Upper and Middle Paranapanema, São Paulo state, Brazil.

O objetivo deste estudo foi coletar e reunir informações sobre a diversidade de anfíbios e répteis nas bacias hidrográficas do Alto e Médio Paranapanema, estado de São Paulo e avaliar os impactos que o pastoreio de gado pode provocar na riqueza e abundância de anuros e lagartos de formações abertas de Cerrado. A riqueza de anuros registrada no Alto Paranapanema é muito superior a encontrada no Médio Paranapanema, existindo um gradiente decrescente na riqueza de espécies partindo da porção sul e sudeste do Alto Paranapanema, onde predominam a floresta ombrófila, em direção ao Médio Paranapanema que apresenta formações de Cerrado e floresta estacional. O pastoreio de gado não causou efeitos negativos na riqueza e abundância total dos anuros e lagartos amostrados. É possível que a intensidade de pastoreio ocorrida nestas formações não foi suficiente para promover modificações consideráveis na estrutura das fitofisionomias, o que pode ter minimizado alterações nos nichos ecológicos das espécies.The aim of this study is to collect information on the diversity of amphibians and reptiles in the hydrographic basins of the Upper and Middle Paranapanema, São Paulo state and assess the impact that cattle grazing can provoke on the species richness and abundance of anurans and lizards of open Cerrado formations. The species richness of anurans reported in the Upper Paranapanema is far greater to that found in the Middle Paranapanema, with a decreasing gradient in the richness from the southern and southeastern portion of Upper Paranapanema, where the ombrophilous forest predominates, towards the Middle Paranapanema in which Cerrado formations and seasonal forests are dominant. Cattle grazing did not cause negative effects on the species richness and total abundance of the anurans and lizards sampled. It is possible that the intensity of grazing was insufficient to cause significant changes in the structure of the phytophysiognomies, which could have minimized alterations in the ecological niches of the species

Herpetofauna da Estação Ecológica de Bauru, um fragmento de Mata Atlântica no estado de São Paulo, Brasil. Herpetofauna from Estação Ecológica de Bauru, a fragment of Atlantic Forest in the state of São Paulo, Brazil.

A herpetofauna do estado de São Paulo pode ser considerada a mais conhecida no país. No entanto, ainda existem consideráveis lacunas amostrais, sobretudo em remanescentes de vegetação natural presentes na região central do estado. Nesse contexto, o objetivo deste estudo foi gerar informações sobre a composição, riqueza e abundância de anfíbios e répteis na Estação Ecológica de Bauru, um fragmento de Mata Atlântica presente no centro-oeste do estado de São Paulo. O levantamento das espécies foi conduzido mensalmente de outubro/2007 a março/2008, totalizando 30 dias de inventário. A amostragem foi realizada por meio de armadilhas de interceptação e queda, encontro ocasional, procura auditiva e procura visual. Foram registradas 20 espécies de anfíbios pertencentes a nove gêneros e quatro famílias (Bufonidae, Hylidae, Leptodactylidae e Microhylidae) e oito espécies de répteis pertencentes a oito gêneros e sete famílias (Amphisbaenidae, Dactyloidae, Gymnophthalmidae, Mabuyidae, Teiidae, Dipsadidae e Viperidae). Este estudo contribui para ampliar o conhecimento sobre a diversidade de anfíbios e répteis na Mata Atlântica, um dos hotspots mundiais prioritários para a conservação biológica. The herpetofauna of São Paulo state is the best known in Brazil. However, there are still considerable sampling gaps at the natural vegetation remnants present in the central region of the state. The purpose of this study was to obtain information on species composition, species richness and abundance of amphibians and reptiles recorded at Estação Ecológica de Bauru, a fragment of Atlantic Forest in the Midwest region of the state of São Paulo. The inventory was conducted monthly from October/2007 to March/2008, totaling 30 sampling days. Surveys were performed using pitfall traps, incidental encounters and acoustic and visual searches. I recorded 20 amphibian species, belonging to nine genera and four families (Bufonidae, Hylidae, Leptodactylidae e Microhylidae), and eight reptile species belonging to eight genera and seven families (Amphisbaenidae, Dactyloidae, Gymnophthalmidae, Mabuyidae, Teiidae, Dipsadidae and Viperidae). This study expands the knowledge about the diversity of amphibians and reptiles in the Atlantic Forest, a global biodiversity hotspot

Lagartos da Floresta Estadual de Pederneiras, estado de São Paulo, Brasil. Lizards from the Pederneiras State Forest, state of São Paulo, Brazil.

Apesar de a fauna de répteis do estado de São Paulo ser considerada a mais conhecida no país, ainda existem consideráveis lacunas amostrais, sobretudo em remanescentes de vegetação natural presentes na região central do estado. Nesse contexto, o objetivo deste estudo foi gerar informações sobre a diversidade de lagartos na Floresta Estadual de Pederneiras, uma unidade de conservação na região central do estado de São Paulo que apresenta talhões de reflorestamento e fragmentos de floresta estacional semidecidual. O levantamento das espécies foi conduzido mensalmente de janeiro/2012 a março/2013, totalizando 70 dias de inventário. A amostragem foi realizada por meio de armadilhas de interceptação e queda, encontro ocasional e procura visual. Foram registradas na localidade cinco espécies de lagartos pertencentes a cinco gêneros e quatro famílias (Dactyloidae, Gymnophthalmidae, Mabuyidae e Teiidae). Este estudo contribui para ampliar o conhecimento sobre a diversidade de répteis na Mata Atlântica, um dos hotspots mundiais prioritários para a conservação biológica. Although the reptile fauna in the state of São Paulo is the best known in Brazil, there are still important sampling gaps, especially within the natural vegetation remnants present in the central region of the state. This study aimed to obtain information on the diversity of lizards at the Pederneiras State Forest, a protected area in the Central region of the São Paulo state, which presents reforestation areas and fragments of seasonal semideciduous forest. The species inventory was conducted monthly from January/2012 to March/2013, totaling 70 sampling days. Surveys were performed using pitfall traps, incidental encounters and visual searches. We recorded five lizard species belonging to five genera and four families (Dactyloidae, Gymnophthalmidae, Mabuyidae and Teiidae).
