CANTOS DE Ololygon centralis (POMBAL & BASTOS 1996) (ANURA; HYLIDAE) EM RESPOSTA A ESTÍMULOS COESPECÍFICOS

Abstract

The vast majority of frogs communicate primarily through acoustic signals. Ololygon centralis an anuran found in the state of Goiás is no different from this vast majority, it uses four different corners to perform its social interactions, they ensure the permanence of the species in nature, through the announcement song, which has as one of the In order to attract females and thus reproduce themselves, the short and long aggressive singing has the function, for example, of driving away the competing males and also avoiding body fighting and in addition to the displacement singing that performs territorial function. Because this species has such a restricted distribution, there are almost no studies on it. To help reduce this data deficit, this paper studies how the use of co-specific playbacks with different amounts of ad and short aggressive corners influence the temporal and spectral variables of those corners. It was found that the playbacks changed the patterns of the temporal and spectral variables, but that such modification was not presented for all variables and not for the announcement corner.
