Since invading the Great Lakes, filter-feeding zebra and quagga mussels have brought increased water clarity to lakes Michigan, Huron, and Ontario. This has boosted the growth of bottom-dwelling filamentous algae like Cladophora, which washes ashore in stringy green mats to foul beaches and harbor harmful bacteria. The invading mussels also recycle phosphorus — a nutrient that feeds algal growth — through their feces. Pengfei Xue, an assistant professor in the Michigan Technological University Department of Civil and Environmental Engineering, will lead a team building computer models to simulate how wave and current patterns influence the distribution of mussel-boosted phosphorus levels. They will investigate how that cycle affects Cladophora growth near Sleeping Bear Dunes and Grand Traverse Bay.
