Intrapopulation variation includes age and sexual variation, but also individual niche specialization. Individual specialization has important effects on dynamics at population or community levels. Environmental intraspecific interactions are factors that can promote enhance this kind of variation. Despite its relevance, knowledge about in amphibians is still scarce, especially species from temperate regions. In study we analyzed the intrapopulational trophic Hypsiboas pulchellus a southern Uruguay. Particularly, ontogenetic diet. We found diet as result shift flies to beetles with increasing body size frogs, there were no differences between males females. evidence specialization, which varied seasonally together width; during warm season (October–March), TNW both increased.
