Description
Summary:Anuran diet studies in Tropical Forests such as the Brazilian Atlantic Rainforest (BAF) are common for adults, but few analyses include juveniles probably because they are less frequent along the year in comparison to adults. Diet composition can vary depending on seasonal prey abundance and differences in body size during ontogeny. Rhinella ornata occurs in BAF, from south of Espírito Santo to north of Paraná state, and possibly in Argentina and Paraguay. Available ecological information on R. ornata is restricted to its reproductive modes, development and body size, ecosystems energy flow, activity and adults feeding habits, microhabitat use and daily activity period. However, there are no studies focusing on juvenile's main microhabitat and feeding ecology. Here, an analysis on the microhabitat use and diet of Rhinella ornata juveniles in an insular BAF habitat is highlighted.
