Work in the Westley Lab seeks to understand how freshwater fishes respond and adapt to abrupt environmental perturbations with the overarching goal of illuminating the processes that give rise to the patterns of within-species diversity in nature.
It is increasingly clear that within-species diversity acts as a diverse portfolio to buffer population-complexes against environmental perturbations. This diversity may ultimately influence the probability of long-term population persistence. But how does this portfolio evolve in nature? How quickly can it arise? To what degree do environmental and genetic factors interact to shape this diversity?
