This site belongs to Prof. Daniel J. Hornbach, Professor of Biology at Macalester College. It was primarily started in an attempt to facilitate information search and retrieval for individuals within the Macalester College Departments of Environmental Studies and Biology. Much of the content deals with our research on freshwater mussels in the St. Croix River, MN and WI. We are especially interested in mussel conservation efforts and the relationship between changing land-use patterns and the long-term health of mussel communities. We have a new project starting in 2014-15 in collaboration with the St. Anthony Falls Research Lab at the University of Minnesota. We will be examining the impact of high sediment loads on mussels in the MN River and in flumes at the lab.

We have also become involved in the Ecological Research as Education Network (EREN) and are examining the impact of riparian vegetation on water temperature variation in small order streams.
