Abstract

Is paper concerns the diet of juvenile Leptodactylus ocellatus, the predator-prey size relationships, and the changes in diet as the frogs grow. The trophic spectrum was quantified, and niche diversity and amplitude, prey size, and index of relative importance were calculated. Results show that L. ocellatus has a generalist diet, consisting mainly of insects and arachnids. A positive correlation between size frogs and prey was found, and a change of diet with increasing body size.

Key words:

Anura; Leptodactylus ocellatus; dinámica trófica; islas del Paraná
