Biography
Dan is from Michigan originally and received his BS from Michigan State University, MS from Eastern Michigan University and PhD from University of Pittsburgh. Dan joined the Arkansas Cooperative Fish and Wildlife Research Unit in 2000, where he is the Assistant Unit Leader and Professor in the Department of Biological Sciences. His research has focused on factors affecting population and community dynamics of freshwater fish and invertebrates, especially the role of disturbance in community dynamics, impacts of invasive species in aquatic ecosystems, and aquatic ecosystem conservation. As part of this work, Dan attempts to bridge the gap between studies done at small spatial scales and the larger spatial scales necessary to understand how disturbance and environmental factors affect population and community dynamics in stream ecosystems. These projects and related work are carried out using a combination of observation, experimentation in the field and lab, and modeling approaches. Dan teaches Biometry, Fish Ecology and Conservation Biology as well as seminars in current topics in Ecology, Conservation Biology and Fisheries.
