Diversity of amphibians in Wandoor, South Andaman, Andaman and Nicobar Islands, India
In this study, for the first time, we present quantitative information about the species richness, habitat associations and abundances of insular frog species in Wandoor, South Andaman Island, Bay of Bengal, India. During our surveys spanning across pre and post-monsoon seasons, we recorded six species of anurans including two endemics. Another endemic sub-species was observed opportunistically. The Anuran community in the study site was found to be uneven (J’ = 0.34), dominated by the Dicroglossid Limonectes cf. hascheanus. Of the different forest types surveyed, littoral forests were found to harbor all the species recorded, followed by evergreen forests which were inhabited by five species; paddy fields, occupied by four species and the mangroves supported just one specialist species, Fejervarya cf. cancrivora. A considerable amount of similarity (82%) was observed between paddy fields and secondary forests in their Anuran species composition, followed by primary evergreen forests (76%). Possible reasons for the observed patterns in habitat associations of the frog species are discussed.
