Abstract


Diet studies allow us to understand important questions about a species behavior in relation to resource use. Aplastodiscus perviridis Lutz 1950 is an arboreal anuran that occurs in southern and southeastern Brazil and western Argentina. In this study, we described and analyzed the diet composition of a population of A. perviridis in southern Brazil. We evaluated the diet by examining the gastrointestinal contents of 42 specimens, 12% of which had no gastrointestinal content, while 12 prey categories were registered. Acarina, Araneae, Coleoptera-adults and Lepidoptera-larvae were the prey categories with the largest relative importance values. The trophic niche breadth was lower than those recorded for other hylids, suggesting a more specialized character.

Keywords: prey, niche, behavior, Araucaria forest, predation.
