“…Young individuals of Physalaemus cuvieri and P. centralis are very difficult to identify in the field and thus both species were here considered together as Physalaemus cuvieri/centralis. Almost all species of frogs and lizards sampled in this study are grassland and savanna specialists (e.g., Brasileiro et al, 2005;Araujo et al, 2013Araujo et al, , 2014. The few exceptions are habitat generalists that can be found in areas of forest as well as in disturbed areas (e.g., Ameiva ameiva among lizards and Physalaemus cuvieri among frogs).…”

Although savannas are fire-adapted ecosystems, prescribing fire for biodiversity conservation remains controversial at least in some regions where savannas occur. Faced with uncertainty, many decision makers and even scientists are still reluctant to prescribe fire for conservation purposes in fire-prone ecosystems, invoking the precautionary principle. Knowledge gaps on the ideal fire regime, such as how and when to burn, and especially the fear of biodiversity losses, are among the main arguments against fire management applied to remnants of native savanna vegetation. To inform this debate, we assessed the impact of prescribed fires on diversity of plants (different growth forms), ants, frogs, lizards, birds, and small mammals, in savannas and grasslands of the Brazilian Cerrado. We assessed the existing species richness, composition, and abundance in areas subjected to long periods of fire suppression and compared to that observed over a short period after prescribed dry-season fires, within each group of plants and animals. Whenever possible, we carried out separate analyses for grassland and savanna. Burning did not significantly reduce species richness of any of the groups analyzed, but had a positive effect on richness of graminoids in grassland. When analyzed at the species level, abundance of most animal groups did not show consistent responses to fire, except for a decrease in some frog populations in grasslands. Forbs, graminoids, and subshrubs increased in abundance after fire in grassland areas, though in savanna areas, abundance of forbs, and subshrubs tended to decline after fire. Species composition changed little in response to fire as indicated by low levels of dissimilarity between burned and unburned areas. These results confirm the high resilience of Cerrado biota to fire, as expected for savanna ecosystems in general. Besides, we demonstrate here that the risk of biodiversity losses cannot justify the objections to the use of prescribed fire for conservation purposes in the Cerrado.

“…As espécies Notomabuya frenata e Ameiva ameiva, abundantes no presente estudo, também obtiveram uma elevada frequência de ocorrência em estudos realizados Fauna de répteis da Fazenda Cambuhy na Estação Ecológica de Assis e na Estação Ecológica de Santa Bárbara (ARAÚJO; ALMEIDA-SANTOS, 2011;ARAÚJO et al, 2014). A espécie Salvator meriane foi a mais abundante ao longo do presente estudo.…”

“…Essa espécie parece não apresentar alta frequência de registros em habitats conservados, como é o caso das Unidades de Conservação do estado de São Paulo (e.g. THOMÉ, 2006;ALMEIDA-SANTOS 2011;ARAÚJO et al, 2014). A alta frequência de registros dessa espécie pode se dar pelo fato de possuir capacidade de invadir ou colonizar, com relativo sucesso, ambientes antropizados ou com algum grau de alteração (ZAHER et al, 2011).…”

http://dx.doi.org/10.5007/2175-7925.2017v30n1p79A região Noroeste é a mais desmatada e com menor concentração de Unidades de Conservação do estado de São Paulo. Apesar dos avanços científicos recentes, ainda existem lacunas de conhecimento de herpetofauna. O presente estudo teve como objetivo fornecer informações sobre riqueza, abundância e uso do habitat dos répteis da Fazenda Cambuhy, que abrange os municípios de Matão, Nova Europa e Tabatinga. As amostragens ocorreram entre os anos de 2013 a 2015, utilizando-se quatro metodologias: armadilhas de interceptação e queda, procura visual limitada por tempo, procura em estradas e encontros ocasionais. Foram incluídos também os registros disponíveis em coleções científicas e na literatura. Foram registradas 46 espécies de répteis pertencentes aos grupos Squamata e Crocodylia. As espécies mais frequentes foram Salvator merianae (N = 55), espécie mais abundante em todos os ambientes amostrados, Notomabuya frenata (N = 14), amostrada somente nas florestas e Ameiva ameiva (N = 4), registrada nos ambientes antrópicos e florestais. A composição de espécies registrada reflete o posicionamento da área de estudo, apresentando a maioria das espécies associadas aos biomas Cerrado e Mata Atlântica. A riqueza de répteis da Fazenda Cambuhy representa 21% da riqueza de répteis do estado, sendo de grande significância para conservação da herpetofauna da região Noroeste do estado de São Paulo.

“…Several protected areas in the southern portion of the Cerrado include a mosaic of typical vegetation types of the biome (from grasslands to woodlands), which has contributed to maintaining a high species diversity of amphibians and reptiles within their limits (Sawaya et al 2008;Araujo et al 2010Araujo et al , 2013Araujo et al , 2014Araujo and Almeida-Santos 2011). Thus, these protected areas may guarantee the persistence of populations of several species, contributing to the conservation of this rich fauna.…”

The natural history of a cerrado snake community in a protected area in southeastern Brazil (Santa Bárbara Ecological Station; SBES) is described. A visual guide and an identification key are also provided to assist researchers and local people in identifying snakes in that region. Sampling was performed through pitfall traps, time-constrained search, accidental encounters, and observations by local people for two years, which corresponded to 240 days of sampling. Among the 388 individuals found in the field, 33 snake species belonging to 21 genera of seven families were recorded. Most species were restricted or found at least once in non-forest vegetation types (campo sujo, campo cerrado, and cerrado sensu stricto) and a few were restricted to forest habitats (cerradão). Our results show that most species (1) occupy open areas; (2) present both diurnal and nocturnal activity; (3) are primarily terrestrial; (4) include lizards, mammals and/or anurans in the diet; (5) present seasonal reproductive activity; and (6) use mainly visually oriented defensive tactics. Despite its small size (3,154 ha), the SBES harbours preserved habitats and a rich and typical Cerrado snake fauna, including threatened species. Furthermore, most of the SBES snakes occur in non-forest environments (54%) and some species are sensitive to habitat disturbance.
