The Eco-Evolutionary Maintenance of Genetic Variation
A longstanding aim of evolutionary biology is to identify and characterize the processes that maintain genetic diversity counteracting its loss from directional selection and gene-tic drift. In 1949 JBS Haldane suggested that antagonistic coevolution should maintain variation due to its negative-frequency-dependent-like reciprocal natural selection. Here I will present some recent and ongoing work on testing the robustness of this component of the Red Queen Hypothesis. Specifically, I will examine if and how interactions bet-ween three ecological processes (species interactions, habitat structure, and population dynamics) impact the evolution of genetic diversity. In doing so I will highlight important overarching principles and practices of eco-evolutionary modelling.
