Talk by HARIKRISHNAN SURENDRAN

A talk by  Dr. Harikrishna Surendran, Consultant Scientist, Metastring Foundation, Bangalore

Abstract:

The concept of ecological niche has been integral to much of ecology in the last century. Theories of biodiversity have for the most part attempted to explain the existence of multiple species in ecological communities through the lens of niche utilization, overlap, competition, and division of resources. Deriving from niche theory, a much debated phenomenon in island ecology has been whether the presence of similar species in a community (species co-occurrence) is affected by interspecific interactions such as competition for resources. However, evidence from studies on ecological communities in the Andaman and Nicobar Islands suggests that competition for resources is not a major driving force behind the co-occurrence of species in islands. This was true for other well-known ecological patterns as well. Rather, the answers to the questions of community assembly seem to be in the evolutionary history of the organisms in relation to geographic factors.
