The amphibian diversity of selected agroecosystems in the southern Western Ghats, India

Abstract

A study was conducted to evaluate amphibian diversity in selected agroecosystems of central Kerala within the southern Western Ghats of India, from January to May 2017. A total of 10 anurans were recorded from cashew plantation, coconut plantation, homegarden and rubber plantation using a combination of quadrat sampling and visual encounter survey. We recorded three species endemic to the Western Ghats: Minervarya keralensis, Pseudophilautus wynaadensis and Indosylvirana urbis from these agroecosystems. Pseudophilautus wynaadensis is a threatened species with Endangered status as per the IUCN Red List. The present study shows a strong relationship between the types of agroecosystems and abundance of different amphibian species. This study highlights the potential of agroecosystems within and adjacent to the Western Ghats mountains to act as important abodes to conserve generalist species of amphibians and to provide a suitable habitat for threatened and endemic species.
