Análise comparada do canto de anúncio de Aplastodiscus eugenioi (Anura: Hylidae) de diferentes populações ao longo da distribuição geográfica da espécie

Abstract

This study investigates similarities in the advertisement call of Aplastodiscus eugenioi and A. albofrenatus, as well as examines possible variations in acoustic parameters related to geographic isolation in continental islands. It was observed that the calls of A. eugenioi and A. albofrenatus are extremely similar, however, there was no taxonomic action taken. Furthermore, the female matting choice seems to act upon acoustic characters which vary little, or simply isolation time is not yet sufficient, thus it is difficult to detect any variation in acoustic analyses. Deeper complementary analyses using another type of investigation tool are necessary in order to achieve a more secure ultimate decision about the taxonomic status and the evolution of these species in continental islands.
