The Holgerson Lab of Freshwater Ecology is housed within the Department of Ecology & Evolutionary Biology at Cornell University. Our lab broadly studies how freshwater communities and ecosystems operate, and how they respond to environmental change. Our current research questions focus on freshwater food webs, community composition, greenhouse gases, and the importance of benthic-pelagic connections. We often study pond ecosystems, which are globally abundant and serve as hotspots for biodiversity and biogeochemical activity (but we like lakes and wetlands, too!).
