Bioacoustics of Sri Lankan Amphibians: a Review of Current Knowledge and Conservation Significance

Acoustic inventory of Sri Lankan amphibians is still in a primitive stage. So far, only 20 amphibian species are known acoustically and are about 16% of the island amphibian fauna. Altogether, twelve publications provide primary acoustic characters, yet the majority of them are not quantitative. Bioacoustics is a powerful tool that can use in many disciplines, including taxonomy and conservation. This work emphasises that the current knowledge on the vocalisation of Sri Lankan amphibians is not adequate and highlighted its applications towards conservation and planning.
