Integrating littoral zone dynamics into our understanding of lake ecosystems is a primary focus of research in the Vadeboncoeur lab. We are particularly interested in the contributions of littoral attached algae (periphyton) to whole lake carbon and nutrient budgets as well as the incorporation of periphyton into food webs. Our main study lakes are in northern Wisconsin and east Africa, but we have also studied lakes in Greenland, Denmark, Quebec, and California, USA. In addition to periphyton, fish and benthic macroinvertebrates figure prominently in our research. Ongoing projects include analyses of the distribution of darters in Ohio streams and the spatial distribution of fish and invertebrates in the large lakes of the world. These projects all have
