Alexandru Hening, Tufts, A general theory of coexistence for ecological communities
- This event has passed.
A fundamental problem from population biology is finding conditions under which interacting species coexist or go extinct. I present results that lay the foundation for a general theory of stochastic coexistence. This theory extends and makes rigorous Modern Coexistence Theory and leads to resolving a number of conjectures due to Chesson, Ellner, and Palis. I explain how this theory can be used to show that random environmental fluctuations can rescue species from extinction. I finish by explaining how one can extend the theoretical framework in order to include eco-evolutionary processes and test the theoretical results by running microcosm experiments with rotifers, protozoa, and bacteria.
