Explore the fascinating world of reptile biodiversity on Indian Ocean islands in this 59-minute lecture by Dr. Ashwini Mohan. Discover how terrestrial reptiles, particularly geckos, have colonized and evolved on diverse island ecosystems, from the large island-continent of Madagascar to the smaller volcanic Comoros and Mascarenes archipelagos, and the complex Andaman and Nicobar Islands. Learn about the unique mechanisms of speciation, complex colonization histories, and the valuable lessons in evolution gained from studying these island ecosystems. Gain insights into the links between geographical features, ecological opportunities, and reptile biodiversity, with a focus on geckos and their remarkable ability to adapt and diversify in isolated environments. Delve into Dr. Mohan's research findings and her passion for uncovering the intricate stories of gecko evolution in the western Indian Ocean islands.
