Resumo: The similarity of life-history traits among closely related species is a well-known pattern in evolutionary biology. Thus, closely related species tend to be more akin to each other than to distantly related ones. The propensity of closely related species to conserve climatic niche features over macroevolutionary time can be defined as climatic niche conservatism. Recent studies have shown the importance of environmental variables with regards to the diversity and distribution of anurans with differences in their reproductive traits under an evolutionary perspective. In this work, using frog species in the Hylidae family, we tested the hypothesis that species more independent from main bodies of water for reproduction are restricted to areas with higher temperature and precipitation means. We also investigated the evolution of climatic niche features of species with different degrees of dependence on water for reproduction. Our results corroborate the first hypothesis and show that terrestrial egg-laying species, in the Hylinae subfamily, have more conserved climatic niche position when compared to Hylinae species that deposits their eggs and tadpoles in main water bodies. Thus, we suggest that reproductive modes are associated with variation in the evolution of climatic niches of frogs.
