An insight into the bioacoustics of some anurans of Meghalaya, India (Amphibia: Anura)

This paper presents an analysis of the temporal and spectral acoustic variables of nine anuran species across six families living in Meghalaya. The species accounted for in the study include the Jerdon’s tree frog Hyla annectans, Long-tongued Forest Frog Hylarana leptoglossa, Northern Pointed-Snout Frog Clinotarsus alticola, Mymensingh Chorus Frog Microhyla mymensinghensis, Beautiful Painted Frog Kaloula pulchra, Double-spotted Oranged Webbed Tree Frog Rhacophorus bipunctatus, Shillong Bush Frog Raorchestes shillongensis, Pierrei Cricket Frog Minervarya pierrei, and Smith’s Litter Toad Leptobrachium smithi. For four out of nine species (Hylarana leptoglossa, Clinotarsus alticola, Microhyla mymensinghensis, and Rhacophorus bipunctatus), this is the first account of their calls; the remnant five recordings add considerable knowledge to the species’ acoustic variability. This study opens up potential benefits for taxonomy, ecology, and conservation.
