|Title:||DISCOVERY, PARENTAL CARE, AND CONSERVATION OF FROGS IN THE WESTERN GHATS OF INDIA||Authors:||SESHADRI KADABA SHAMANNA||ORCID iD:||orcid.org/0000-0002-6788-7860||Keywords:||Amphibians; India; Conservation; Parental Care; Taxonomy; Ecology||Issue Date:||4-Aug-2017||Citation:||SESHADRI KADABA SHAMANNA (2017-08-04). DISCOVERY, PARENTAL CARE, AND CONSERVATION OF FROGS IN THE WESTERN GHATS OF INDIA. ScholarBank@NUS Repository.||Abstract:||A third of all amphibians are threatened globally and yet, several knowledge gaps exist. The Western Ghats of India is a global biodiversity hotspot where amphibians are underrepresented in research. Findings reported here contribute to advancing our knowledge about amphibians in aspects of Taxonomy, Systematics, Reproductive Ecology and Conservation. I discovered two new species of frogs and subsequently, re-described another. I also present a case to resolve a taxonomic problem of the White Spotted Bush Frog (Raorchestes chalazodes), which was presumed extinct and was rediscovered in 2011. Ecological studies on this species led to discovery of a novel reproductive mode wherein, adults enter bamboo stalks via narrow openings and lay direct developing eggs and provide parental care. I then established the evolutionary significance of parental care behavior in R. aff chalazodes by conducting in-situ adult removal experiments. Evidence suggests male parental care behavior increases offspring survivorship as it prevents egg predation. With an ultimate goal of conserving R. aff chalazodes and bamboo habitats, I mapped their geographic distribution using species distribution modeling. Finally, I synthesize my contributions in the context of existing knowledge about diversity and reproductive ecology of amphibians and identify avenues for further research.||URI:||http://scholarbank.nus.edu.sg/handle/10635/138902|
