Ecological interactions, evolutionary adaptation, and the dynamics neutral genetic diversity

Ecological interactions, evolutionary adaptation, and the dynamics neutral genetic diversity

Series: Quantitative Biology Colloquium
Location: Math 402
Presenter: Joseph Matheson, Ecology & Evolutionary Biology, University of Arizona

The purpose of the presentation is to introduce the work of Dr. Régis Ferrière on understanding how variation in neutral molecular sites evolves, and how patterns of neutral molecular evolution can be used to infer the history of adaptive trait evolution. I'll describe the mathematical framework for finite population dynamics in continuous time, and discuss the result that the stochastic individual-based process they use converges to a new measure-valued diffusive process with jumps that Ferrière et al. call the Substitution Fleming-Viot Process (SFVP). I'll then discuss the implications of the SFVP for our understanding of the dynamics of neutral variation and adaptive traits when there are interactions between ecology and evolution ("eco-evolutionary feedbacks").
