Abstract Details

2009, Master of Science, University of Toledo, Biology (Ecology).
Microcystis blooms are annual occurrences in western Lake Erie. Field measurements of Microcystis biovolumes from 2002- 2008 show that blooms are most dense in waters adjacent to the Maumee Bay. This suggests that conditions within these waters support rapid Microcystis growth. Field measurements and a laboratory experiment showed that the high turbidity of the bay and adjacent waters alleviated high- light stress which results in less photo-inhibition, while Microcystis in less turbid water had more photo-inhibition. Damage occurs to Microcystis during a surface bloom as a result of prolonged time in high-intensity light. Further, Microcystis from nearshore water had higher protein content then that of offshore which indicates greater cellular health. This is likely a function of turbidity and high soluble nutrients in turbid waters. Therefore, reduced sediment loading would presumably increase growth stress for Microcystis and would lessen the magnitude of blooms seen in western Lake Erie.
