Northward shifts in the distribution of African fishes in association with climate change
Climate change is a key driver of biodiversity loss across the globe, and freshwater fishes are predicted to be among the most vulnerable taxa. Despite this, freshwater fishes have been disregarded in nearly all climate change assessments. Our research group integrates the morphology and physiology of freshwater fishes with their ecology and evolution to understand the effects of multiple and potentially interacting environmental stressors. Specifically, I am interested in understanding how range expansion of freshwater fishes coincident with climate warming is affected by response to a second strong environmental gradient – dissolved oxygen. This research will allow us to understand the ecological and evolutionary implications of range shifts for both the species that disperse and the communities that they invade.
