“…Scinax sp. (Scinax catharinae clade) was found in riparian forest of streams and lentic environments near forest edges, in general these species are gallery forest dwellers that use marginal vegetation bordering streams (Lutz 1973;Lourenço et al 2009;Pombal et al 2010;Leite et al 2013). Scinax fuscomarginatus has been already found in temporary and permanent ponds near to forest edges and in open areas.…”

Even harboring a high diversity and many endemic species of amphibians and reptiles, the Cerrado biome has shown drastic changes due to the conversion of natural areas into pastures and plantations. Here, we present a checklist of amphibians and reptiles from southeastern state of Goiás, Central Brazil. This checklist was the result of collecting efforts of an inventory along the basin of the Piracanjuba and Peixe rivers carried out between September 2010 and January 2011. We recorded 39 amphibians and 40 reptiles. These results were also compared to other studies in the Cerrado biome. Our results showed that this region has a rich herpetofauna, despite the progress of anthropogenic activities in the region.

“…Scinax is currently the largest genus in the family Hylidae with 112 recognized species (Frost, ; Lourenço et al ., ), and more new species are being described frequently (e.g. 14 new species described in the last three years: Cardoso & Pombal, ; Lourenço, Nascimento & Pires, ; Faivovich, Gasparini & Haddad, ; Nunes, Carvalho & Pereira, ; Nunes & Pombal, , ; Pombal et al ., , ; Cruz, Nunes & De Lima, ; De Lima, Cruz & de Azevedo, ; Silva & Alves‐Silva, ; Lacerda, Peixoto & Feio, ; Nunes, Kwet & Pombal, ). The last phylogenetic assessment of this genus revealed two main clades, the Scinax catharinae clade, including the S. catharinae and Scinax perpusillus groups, and the Scinax ruber clade, including the Scinax rostratus and Scinax uruguayus groups, and 43 species not being assigned to any of the previous groups (Faivovich et al ., ).…”

Scinax fuscomarginatus, Scinax parkeri, Scinax trilineatus, Scinax lutzorum, and Scinax pusillus are morphologically similar species with controversial taxonomy associated with open formations of South America east of the Andes. We used external morphology, advertisement call, and molecular sequences to assess the taxonomy of these species. Phylogenetic analysis of molecular data showed a well‐supported monophyletic group divided into two main clades and several subclades. Specimens of Hyla madeirae (synonym of S. fuscomarginatus) and those from Serra do Cachimbo correspond to distinct subclades, whereas the currently valid species were grouped into a single clade. This clade showed a marked substructure, but concordance of the recognized species to subclades was limited, showing S. fuscomarginatus to be paraphyletic with respect to S. parkeri, S. trilineatus, S. lutzorum, and S. pusillus. The high intrapopulation and intraspecific variation found in morphological characters did not allow us to differentiate amongst the currently recognized species. Similarly, none of them was distinguishable by morphometric analysis or advertisement call. Based on multiple evidence, we propose the synonymy of S. parkeri, S. trilineatus, S. lutzorum, and S. pusillus with S. fuscomarginatus, the revalidation of H. madeirae, and describe the specimens from Serra do Cachimbo as a new species. © 2014 The Linnean Society of London

“…The treefrog Bokermannohyla circum data always inhabits stream habitats in the Atlantic Rain Forest (Napoli 2005), where the species uses the herbaceous vegetation to breed, and its tadpoles develop in the small rivulets and flooded adjacent areas (Napoli 2000). Species of the Scinax catharinae Group typically are forest dwellers (Pombal et al 2010); thus, it is not surprising Scinax sp. 2, a member of this species group, is restricted to the densest forest patches of the PESP with lotic environments.…”

Contribution of environmental variables to anuran community structure in the Caatinga Domain of Brazil. To ascertain the influence of environmental variables on the structure of anuran communities, we conducted tests to determine which variables best explain the spatial distribution patterns of different communities of anurans in a rocky, montane environment characterized mainly by open habitats and gallery forests. The study area is the Sete Passagens State Park in the State of Bahia, Brazil, an area included in the Chapada Diamantina Region and in the Caatinga Morphoclimatic Domain. We sampled 20 plots (60 × 25 m) during two rainy seasons, and measured 13 environmental variables. The environmental matrix was reduced to four synthetic axes through the principal component analysi, and the anuran community matrix was reduced to a synthetic axis through the nonmetric multidimensional scaling method. We tested the association between environmental axes (independent variables) and community composition (dependent variable) using a multiple regression analysis. The single axis significantly associated with the species of anurans found in any given plot is Principal Component 1, in which the major contributors to variation are factors involving vegetation structure, listed in descending order, as follow: percentage of leaf litter, density of trees, canopy height, soil moisture, and percentage of understory, shrub, and herb layers. The ordination of the anuran community showed an environmental gradient from the Campo Rupestre to Semideciduous Forest patches, characterized mainly by the gradual increase of layering in the vegetation.
