The Dell Ecology Lab @ NGRREC works to address basic and applied questions in ecology. We work to uncover the biological mechanisms that drive the extraordinary diversity and complexity seen in nature, with a particular interest in species interactions and the role of the physical environment. We also work to understand how humans and their activities influence natural ecosystems, with the goal of producing science that can inform management and policy. The research questions we address require study across domains of life, levels of biological organization, and habitats (although we have particular interest in the ecology of large rivers and their catchments). We use a range of methods in our research, including field observations and experiments, analysis of published data, laboratory experiments, and theory. We are particularly interested in utilizing emerging technologies, such as automated tracking, to address problems in ecology. Our lab is based at NGRREC, a state-of-the-art field station in Alton, IL, on the banks of the mighty Mississippi River.
