RESEARCH INTERESTS

My primary research interest involves the study of aquatic insects to address both basic and applied ecological questions. Most of my research has focused on the role of aquatic insects in energy flow in lakes and streams. One group of aquatic insects that largely has been ignored in freshwater studies is the dipteran family Chironomidae, the non-biting midges. Although these organisms are frequently the numerically dominant insects in aquatic habitats and have been used extensively in environmental assessment, the time-intensive and difficult nature of collecting and identifying midges has deterred most aquatic ecologists from examining the importance of this group in aquatic systems. My previous research has examined the role of chironomids in streams by assessing their importance in energy flow. Results from this research have demonstrated that chironomids can account for over 80% of aquatic insect secondary production.

Because of the importance of aquatic insects in energy flow in aquatic ecosystems, my current research is examining how the introduction of exotic species in the Great Lakes is altering food webs and energy flow. The Great Lakes have been subjected to a series of invasions by a variety of organisms over the past century. Although many of these organisms have no noticeable impact on ecosystem function, some invasions can result in profound changes to benthic food webs. I have been investigating changes in nearshore Great Lakes food webs resulting from the recent invasions of zebra mussels, round gobies, and Eurasian ruffe. My research has shown that these species have had measurable impacts on benthic food webs resulting in substantial changes in energy flow. These changes in energy flow can influence water quality, the availability of food resources, and the mobilization of toxic substances, such as PCBs, to higher trophic levels.
