Abstract

We studied some reproductive characteristics and diet of the hylid frog Hyla euphorbiacea in a pine-oak forest from Sierra Negra, southeastern Puebla, Mexico. The breeding season lasted from June to September; during this period males exhibited monthly variation in gonadal activity, whereas females did not. Sexual size dimorphism was observed, with females being larger than males, and female size was positively correlated with number and diameter of ovarian follicles. Diet during the rainy season was composed of invertebrates, classified into 16 prey categories. The most important was Lepidoptera (larvae), followed by Coleoptera (adults), and Araneae. Diet diversity and trophic niche overlap between sexes were relatively high. We discuss some recent findings and biological characteristics of H. euphorbiacea, which potentially make this species more susceptible to population declines than other members of the genus.
