Resumo
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 distribution or vocal
behaviour of the other. We found H. albopunctatus and H. paranaiba males emitting advertisement and aggressive calls in
sympatry and allopatry. Although the calling behavior of H. paranaiba did not differ in sympatry and allopatry, differences
were noted for H. albopunctatus. Bioacoustics is the main form of communication in anurans, and is one of the best ways
to discriminate among species. Variations in the calling behavior of males and what drives these variations in both species is
central to better understand the processes of specific recognition and female attraction.
