Climate change is fundamentally altering the quantity and quality of freshwaters on the planet. Understanding how freshwater ecosystems are responding to this change, especially at the base of the food web, is not only fundamental to ecology but also to humans that rely heavily on freshwater for consumption, agriculture, and recreation. The advent of new technology in freshwater ecology makes it possible to evaluate how the complex interactions of climate and human-induced changes are shifting the ecology of rivers and lakes. In our lab group, we evaluate the energetic and biogeochemical consequences of a changing climate in inland waters. We use a suite of tools and emerging resources, from sensors to satellites, to evaluate two broad research questions: 1. What controls the timing and magnitude of inland water ecosystem energetics? 2. How is climate change altering ecosystem energetics in inland waters?
