Abstract

This study looks at resource (trophic, spatial and temporal) use and foraging tactics in a community of eight species of anuran amphibians at a seasonal locality in south India. Within the community, the species are differentiated into a sit-and-wait group, which are large, cryptic and sedentary foragers showing a relatively wide dietary spectrum; and a widely foraging group, whose members are aposematically coloured, and actively forage on a few prey types. However, there are indications that these modes represent ■ two ends of a continuum, with some species showing greater plasticity in prey use than others. Sympatric species, except dietary specialists, were found to generally overlap broadly in diet. Microhabitats are partitioned to a greater degree than food, the most closely related species, which tend to show similar diets, selecting different foraging areas
