Diet of two sympatric species of the Leptodactylus fuscus group: Leptodactylus longirostris (Boulenger, 1882) and Leptodactylus mystaceus (Spix, 1824) in the Brazilian Amazon rainforest

Leptodactylus longirostris and L. mystaceus are sympatric species of frogs occurring in the Amazon basin in forest areas. In this study, diet composition, niche overlap and niche breadth were described for the two of species from the north domain of the Brazilian Amazon forest. A total of 68 individ...

Descripción
Sumario:Leptodactylus longirostris and L. mystaceus are sympatric species of frogs occurring in the Amazon basin in forest areas. In this study, diet composition, niche overlap and niche breadth were described for the two of species from the north domain of the Brazilian Amazon forest. A total of 68 individuals of L. longirostris and 43 individuals of L. mystaceus were analyzed. The most important prey for L. longirostris was Hymenoptera (Formicidae) and for L. mystaceus was Coleoptera. The niche breadth of L. mystaceus was wider than the another species. The value of the niche breadth (B≤0.50) of both sympatric frogs suggests a specialization on ants (Formicidae) and beetles (Coleoptera).
