Alexandru Hening, Tufts, A general theory of coexistence for ecological communities

January 6, 2021 | 4:00 pm - 5:00 pm EST

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.

Alex’s research broadly focuses on stochastic processes, mathematical ecology, infectious disease dynamics, random dynamical systems, evolution, harvesting, and stochastic optimal control.  You can find further details, including a copy of his CV, at his website
