My primary research focus is on the pathways linking key environmental processes across geographic scales. Lakes are typically studied individually, or in small groups in close proximity, and this inhibits identification of mechanisms by which large-scale factors like climate change influence ecosystem patterns and processes. I am conducting research on the cross-scale interactions that link climate and landscape characteristics to the ecological properties of individual lakes. I have discovered emergent patterns in key ecosystem relationships at the regional scale, indicating a higher level of organization than previously observed. These results are critical for improving predictions of ecosystem response to environmental change including changes in primary production and greenhouse gas emissions due to climate warming and lake browning.
