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.

Our paper on the comparative landscape genetics of Oregon spotted frogs and Columbia spotted frogs in Oregon and Idaho has been published in Molecular Ecology! Our main finding was that species traits matter for predicting connectivity. In particular, connectivity was more closely tied to water for Oregon spotted frogs, which are more aquatic than Columbia spotted frogs. In addition, temperature consistently matters for predicting connectivity, although in some landscapes, connectivity is positively related to temperature, whereas in others, it’s negatively related to temperature. Thus, climate change may have different effects on connectivity in different regions. A huge thanks to Jeanne Robertson and Melanie Murphy for leading this collaborative effort. Both are former Funk Lab postdocs who have recently received tenure at California State University Northridge and the University of Wyoming, respectively.
