However, in order to extract authors credited. meaningful biological information from resulting enormous Keywords: acoustic datasets, rapid analytical techniques are required. Here we tested the ability of a suite of acoustic indices to predict diversity; landscape; species richness; avian bioacoustic activity in recordings collected from the Western Ghats; passive acoustic Western Ghats, a biodiversity hotspot in southwestern India.
