Acoustic communication in two species of the Hypsiboas albopunctatus group (Anura: Hylidae) in sympatry and allopatry

ABSTRACT Tropical anuran communities are very diverse. Nevertheless, much of their ecological and historical processes remain unknown. Bioacoustical studies are important to help to solve these puzzles. In the present study we examined the effect of environmental (air temperature and humidity) and morphological (body size) attributes on the acoustic parameters of two frogs of the Hypsiboas albopunctatus species group (H. albopunctatus and H. paranaiba ) living in sympatry and allopatry in the Brazilian cerrado. We also investigated if the presence of one species influences the spatial distribu...
