Evolutionary Dynamics of Pine Squirrels (Tamiasciurus) in Western North America
The evolution of new phenotypes and species is a population genetic process that is governed by four fundamental forces: natural selection, drift, mutation, and gene flow. Ecological genetics is the reciprocal interaction between population genetic theory and empirical observations from nature and the laboratory. Here I present ...
How the chili got its spice: Ecological and evolutionary interactions between fungal fruit pathogens and wild chilies
Most species depend on other species for survival and reproduction, thus coevolution - reciprocal evolutionary change between species - arguably plays a dominant role in the origin and organization of biodiversity. We used a novel model system to study coevolutionary dynamics: wild chili peppers and their fruit-associated ...
