| Research Abstract |
To study population genetic factors affecting community evolution, a series of stochastic simulations was performed that follows the coevolutionary dynamics in an ecological community. Specifically, we developed simulation models based either on (1) stochastic differential equations, (2) traditional Fisher-Wright processes, or (3) birth-death processes. These coevolutionary models were then integrated into a multilocus population genetic framework to describe polygenic selection and adaptation in a two-species interacting system.
