My research addresses questions concerning plant-animal interactions, landscape structure as a determinant of faunal movement and assemblage character, and the effects of anthropogenic and natural disturbance on ecological function. Much of our team's work emphasizes invertebrates, although we utilize other taxa as questions dictate. We have used both experimental and observational approaches, and recent studies have extended across several scales, ranging from patch boundary dynamics at the microhabitat level to experimental manipulations of rivers. This work has taken us to alpine meadows and streams, montane ponds, tropical seagrass meadows, and desert springs and playas.
