520 |a"By using the NWRI nine-box water quality model calibrated for pre-Dreissena years, with the model coefficients unchanged, we demonstrate that changes in phosphorus and dissolved oxygen in post-Dreissena years can be detected by the deviation of computed results from observed data. Through sensitivity analysis, we excluded other possible mechanisms to conclude that Dreissena can affect the phosphorus concentration in Lake Erie. Specifically, the total phosphorus is decreased in the east basin whereas the soluble reactive phosphorus is increased in the west basin. The dissolved oxygen in the lake is, however, not significantly affected by Dreissena. The impact of these and other findings on the phosphorus—dissolved oxygen relationship and its implication to the Lake Erie lakewide management plan is discussed using the results of this study. A new set of experiments has been proposed and is currently being carried out to better understand the Dreissena-phosphorus-plankton relationship and to improve future modelling and monitoring studies"--Abstract.
