Fabrício Hiroiuki Oda, Vinicius Guerra Batista, Priscilla Guedes Gambale, Fabio Teruo Mise, Fagner de Souza, Sybelle Bellay, Jean Carlo G. Ortega, and Ricardo Massato Takemoto (2016) The expansion of agriculture causes habitat loss and fragmentation that negatively affects biodiversity. We analyzed the species richness, composition and habitat preferences of anuran species in aquatic habitats in mesophytic semideciduous Atlantic Forest remnants and surrounding agricultural landscapes in southern Brazil, between April 2011 and March 2013. Nineteen anuran species, belonging to 11 genera and 5 families, were recorded. Species richness was similar between the forest remnants and the agricultural landscapes (18 and 19 species, respectively). Anuran species composition was associated with habitat type and the number of vegetation types in breeding habitats. Most species preferred breeding habitats in the agricultural landscape. Our results suggest that the anuran species recorded have access to both forest remnants and agricultural landscapes, as species richness in the two areas was similar. Habitat type and the number of vegetation types may influence species composition, because vegetation provides shelter and calling sites for anurans, which breed mainly in lentic water bodies. Thus, to maintain anuran populations in fragmented landscapes, it is important to preserve artificially constructed bodies of water within the agricultural landscape and on the forest edge.

Key words: Agricultural ecosystems, Amphibians, Anthropic alterations, Atlantic Forest, Habitat loss.
