Current Research

I conduct research on the ecology of aquatic organisms and how this information can be used to develop effective management and conservation strategies for streams. Most of my current research is focused on understanding causes of freshwater mussel declines throughout the U.S. and much of the world. Mussels are important because, as filter feeders, they have a profound influence on aquatic ecosystem function and health, and a large percentage of North American species are in danger of extinction. My research on mussel declines includes a wide variety of field and laboratory approaches conducted with a broad network of partners. I have also conducted extensive research on freshwater fishes and have experience with aquatic insects, crayfishes, snails, reptiles and amphibians, and many other groups.

Research Highlights

Assessment of conservation strategies for North American freshwater mussels. (2014)
SRS-2014-034 North America has the most diverse freshwater mussel fauna on Earth, but over half of the 300 native species are in danger of extinction. Extensive conservation efforts in the last 30 years have addressed this extinction crisis. A Forest Service scientist critically assessed the effectiveness of those efforts and outlined ways that conservation can be more effective in the future.
