Climate Change

CO${}_2$ in freshwaters is highly variable when compared to marine systems, and it is expected that many freshwater fishes are adapted to short periods of high CO${}_2$. In collaboration with Drs. Cory Suski and Caleb Hasler, we have published on the effects of CO${}_2$ on fishes and invertebrates. Current lines of inquiry involve using macroscale and long-term water quality data sets to calculate historic and current levels of CO${}_2$ in US flowing waters.
