Thesis (M.S.)--Michigan State University, 2004.

Zebra mussels (Dreissena polymorpha) invaded the Great Lakes of N. America in the mid-1980's, and have rapidly spread into inland lakes, particularly in Michigan. Most research on the impact of Dreissena invasion has been conducted in well-mixed aquatic ecosystems, while little is known about such impacts in thermally-stratified inland lakes. Dreissena invasion has recently been associated with an increase in the toxic cyanobacterium (bluegreen), Microcystis aeruginosa, in low-nutrient lakes but here again, there is little compelling survey data from inland lakes indicating significantly elevated M. aeruginosa biomass in invaded habitats. In addition, no studies have examined whether bluegreen toxins are elevated in Dreissena-invaded lakes.

520 $a Zebra mussels (Dreissena polymorpha) invaded the Great Lakes of N. America in the mid-1980's, and have rapidly spread into inland lakes, particularly in Michigan. Most research on the impact of Dreissena invasion has been conducted in well-mixed aquatic ecosystems, while little is known about such impacts in thermally-stratified inland lakes. Dreissena invasion has recently been associated with an increase in the toxic cyanobacterium (bluegreen), Microcystis aeruginosa, in low-nutrient lakes but here again, there is little compelling survey data from inland lakes indicating significantly elevated M. aeruginosa biomass in invaded habitats. In addition, no studies have examined whether bluegreen toxins are elevated in Dreissena-invaded lakes.
520 $a To address these needs, I conducted a large-scale survey of inland lakes in Michigan that contain or lack D. polymorpha. The surveyed lakes were otherwise similar in nutrients, morphometry, and location. Microcystis aeruginosa biomass was 3.6 times higher and total particulate toxin concentration was 3.3 times higher in invaded lakes. Ciliate biomass was 45% lower and rotifer biomass was 44% lower in invaded lakes. Rotifer richness and diversity were also lower in lakes with D. polymorpha . In addition, a shift in the size distribution of ciliates was found between lake categories indicating that zebra mussels may be reducing larger, algivorous ciliates in favor of smaller bacterivorous ciliates. In general, zebra mussel impacts on microzooplankton biomass in the stratified lakes I sampled were weaker than those reported from well-mixed systems.
