Welcome to the Funk Lab

We strive to understand the ecological and evolutionary mechanisms that generate and maintain biological diversity using population genomics, experimental manipulations, and field studies. Our goal is to not only test basic ecological and evolutionary theory, but also directly inform policy and management decisions that will ultimately determine the fate of biodiversity.

John Kronenberger’s paper on an experimental test of genetic rescue using Trinidadian guppies accepted in Conservation Biology!!!

Congratulations to John Kronenberger–a former Funk Lab MS student–and colleagues for successfully publishing the last chapter of his MS thesis in Conservation Biology. John used replicate lab populations of Trinidadian guppies to test the effects of augmenting small, isolated populations with different types of immigrants. He found no evidence for demographic rescue, but did find genetic rescue in one population that received divergent immigrants. In the second population, the benefits of augmentation were less apparent. Nonetheless, these results add to a growing consensus that gene flow can increase population fitness even when immigrants are divergent from the recipient population.
