Some evolutionary theories predict a relationship between species diversification and morphological divergence within lineages. Differentiation of niches is often accompanied by the selection for divergent phenotypes that further minimize interactions between competitors (character displacement). Therefore, it is expected a strong influence of morphological variation on species within lineages on species coexistence. However, this relationship has little been tested. Here, I propose to test this relationship with morphological and geographical range data from South American hylid frogs. We will quantify morphological variation for mainland tree frogs using 28 measurements. Species distribution and spatial overlap will be based on range maps from available databases. To test the hypothesis that morphological diversification is a function of number of species, species coexistence or a mix of both, we will use phylogenetic generalized least squares to assess evolutionary relationships and null model analysis to assess patterns of trait coexistence across species.
