“…The presence of spiders in the diet of these hylids is probably related to the fact that predator and prey use the same micro-habitat, suspended in shrubs, facilitating the encounter of prey(De Araújo et al 2007, Barbosa et al 2014.Boana bischoffi and B. marginata demonstrated a similar trophic niche breadth, with generalist characteristics. The niche breadths recorded in this study were similar to those recorded for Aplastodiscus perviridis (Bsta = 0.27,Oliveira et al 2017) and B. pulchella (Bsta = 0.31, Oliveira 2014), but smaller than those recorded for B. leptolineata (Bsta = 0.51,Barbosa et al 2014), B. raniceps (Bsta = 0.64, Sabagh et al. 2010 and Scinax acuminatus (Bsta = 0.48,Sabagh et al 2010).…”

The species Boana bischoffi and Boana marginata are endemic to the Atlantic Forest, where they often occur in sympatry. There is a large gap in the knowledge of natural history of both species. In this study, we aimed to describe and compare the diet composition of B. bischoffi and B. marginata in the southern domain of the Brazilian Atlantic Forest. We analyzed the gastrointestinal contents of 43 individuals of B. bischoffi and 30 individuals of B. marginata. Both showed a high trophic niche overlap (0.90 O jk ). The most important prey categories for both species belonged to the orders Araneae and Coleoptera. The species niche breadth (Bsta) varied from 0.35 to 0.42, suggesting a generalist feeding behavior for both species. Our data provide unprecedented information on these species' food composition, contributing to a better knowledge of the natural history of neotropical anurans. Dieta e sobreposição de nicho trófico deBoana bischoffi e Boana marginata (Anura: Hylidae) no sul do Brasil Resumo: As espécies Boana bischoffi e Boana marginata, são endêmicas da Mata Atlântica onde frequentemente ocorrem em simpatria. Existe uma grande lacuna no conhecimento da história natural de ambas as espécies. Nesse estudo, nosso objetivo foi descrever e comparar a composição da dieta de B. bischoffi e B. marginata no limite sul da Mata Atlântica brasileira. Analisamos o conteúdo gastrointestinal de 43 indivíduos de B. bischoffi e 30 indivíduos de B. marginata. Ambas apresentaram elevada sobreposição de seus nichos tróficos (0,90 O jk ). As categorias de presas mais importantes para ambas as espécies pertenciam as ordens Araneae e Coleoptera. A amplitude de nicho das espécies (Bsta) variou de 0,35 a 0,42, sugerindo comportamento alimentar generalista para ambas. Nossos dados trazem informações inéditas sobre a composição alimentar destas espécies, contribuindo para um maior conhecimento da história natural dos anuros neotropicais.

“…We recorded 22 anuran species, which correspond approximately to two-thirds of the richness found in similar forest remnants in southern Brazil (Lucas and Fortes 2008; Iop et al 2012; Bastiani and Lucas 2013). Hylidae represented over half of species, most of which are considered generalists and found in both forest environments and grasslands or forest edges (Lucas and Fortes 2008; Almeida-Gomes and Rocha 2014; Barbosa et al 2014; Oliveira et al 2017). The lack of any strong association between tadpole species richness and land use suggests that anurans are primally affected by habitat characteristics which are detected only on a fine-scale analysis.…”

We evaluated the influence of landscape configuration on the diversity of anurans in Atlantic Forest remnants in southern Brazil. As natural habits provide better conditions for the survival of amphibians, we expected to find more diverse communities in areas with more forest cover. We sampled tadpoles in 28 breeding sites distributed in seven forest remnants. We recorded 22 anuran species and richness varied from 6 to 12 species between sites. Most of the recorded species were not forest specialists, except for Boana curupi and Crossodactylus schmidti. There was a significant overlap in the species composition between all remnants, and the Generalized Linear Mixed Model indicated that landscape use did not affect species richness. The PERMANOVA showed that forest and livestock farming explained the dissimilarity in the composition of the communities. One possible explanation for this is that the remnants are surrounded by a relatively well-preserved landscape, which offers favorable conditions for the maintenance of local populations and homogenizes species composition across the sampling sites. The lack of any strong association between tadpole species richness and land use suggests that anurans are primally affected by habitat characteristics that are detected only on a fine-scale analysis.
