Call Characteristics of Several Anuran Species from East Kalimantan

Abstract

Call characteristics of Ansonia leptopus, Rana cancrivora, R. nicobariensis, R. hosei and Polypedates macrotis, recorded in East Kalimantan, were analyzed with a sound spectrograph. Calls of R. cancrivora could be differentiated in relation to its behaviour and were assigned to the advertisement calls reported for the other Ranid species. Calls of R. nicobariensis were compared with the published data of R. erythraea calls, and likewise, calls of P. macrotis were compared with those of P. leucomystax. The call characteristics were found to significantly differ between these closely allied species.
