h Biological invasions of aquatic communities: controls and impacts
h Plankton ecology, particularly in reservoirs and large rivers
h Biological assessment of water quality
The primary focus of my research is population and community ecology in freshwater environments. My students and I use surveys and experiments to explore the factors that limit the distribution and abundance of aquatic organisms. My primary study organisms have been the freshwater zooplankton, the small animals that eat algae and serve as food for young fish. In recent years, I have focused much attention to dispersal and how that regulates community structure in lakes and ponds. Studies of aquatic invasive species provide a handy vehicle for this research. Favorite study organisms include a tropical cladoceran (Daphnia lumholtzi) and the Chinese mystery snail (Cipangopaludina chinensis), both of which have been highly successful invading lakes and rivers of the coterminous United States. A recent sabbatical provided me the opportunity to study these and other invasive species in the numerous lakes of northern Wisconsin. Other collaborative research has explored planktonic communities of the Missouri, Mississippi, and Ohio rivers. Finally, my students and I have an ongoing interest in assessing water quality of lakes and streams of the Missouri Ozarks.
My graduate students have allowed me to explore many more questions than I would have done alone. Some students have studied other aspects of species invasions, particularly the role of interactions with native species. Other grad students have examined water quality and impacts of global climate change on aquatic invertebrates. Each of my students writes a detailed research proposal, presents their research at professional meetings, and is encouraged to publish. Most of the 19 students who have completed a Master’s thesis under my direction (listed below) have completed their thesis in about two years, many have received awards and grants, and all have jobs in the field of biology or environmental science. This employment success rate attests to both their motivation and the employment prospects related to aquatic ecology.
