N. LeRoy Poff is Associate Professor in the Department of Biology at Colorado State University. He earned an MS in Environmental Sciences at Indiana University and a Ph.D. in Stream Ecology at Colorado State University. His primary research interests in the CSU Stream Ecology Lab are guided by the broad consideration of how ecological processes and patterns are constrained by habitat structure and environmental variability at multiple spatial and temporal scales in aquatic ecosystems. At large scales, his research focuses on testing general ecology theory predicting how the structure and functional organization of biological communities (invertebrates and fish) depend on habitat stability. He has served NEON as a member of the Fundamental Sentinel Unit tiger team.
