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.
