Everywhere we look we can observe the immense diversity in nature. But how does biodiversity occur in the first place? Dr. Uma Ramakrishnan studies biogeography, the field that analyzes biodiversity across space. In her first talk, Ramakrishnan explains factors that shape biodiversity, and shows that biodiversity is higher in tropics, islands, and mountain ranges.
In her second talk, Ramakrishnan describes the biogeography of the Himalaya and the Indian mountain ranges. Her laboratory studies how gaps in mountain ranges can drive the speciation of birds. By analyzing the DNA of 24 species of birds, Ramakrishnan’s laboratory showed that deeper gaps in the mountain range generated higher levels of speciation and biodiversity of birds. Their research may help us to identify and prevent threats to biodiversity hotspots.
Dr. Uma Ramakrishnan is a professor at the National Center for Biological Sciences (NCBS) in Bengaluru, India. Her passion for ecology and evolutionary biology led her to complete a bachelor’s degree in Physics, Chemistry and Math. Ramakrishnan obtained her PhD on population genetics from the University of California, San Diego and continued her postdoctoral training… Continue Reading
