Amphibians from Sabah II. Acoustic Characteristics of Three Common Anuran Species

Abstract

Call characteristics of Bufo juxtasper, Rana erythraea and Polypedates leucomystax recorded at Ranau, Sabah, Northern Borneo, were analyzed with a sound spectrograph. Each of the three species possessed unique call characteristics and suggested the presence of valid preisolating mechanisms. For Bufo juxtasper, characteristics of mating calls were compared with those of release calls. The mating calls of Polypedates leucomystax were suggested to differ from those of the same species from Thailand and Nepal reported by the previous authors.
