Variation of the advertisement call of Physalaemus centralis Bokermann, 1962 (Anura: Leptodactylidae) in the Cerrado of central Brazil.

Acoustic signals are employed to support the correct designation of species and enables the discrimination between individuals. We analyzed both intra and interindividual variability of the advertisement call ofPhysalaemus centralison the basis of specimens recorded in eight localities of the Cerrado in central Brazil. Within-individual variation, most of the call parameters were static properties. Both spectral and temporal call properties were dynamic between individuals. All call proprieties varied more between individuals than within an individual. Our study adds important data for future studies on the taxonomy and phylogeny of theP. cuviericlade.
