| Impact Description | Predictive models showed unionid mortality (reflected by the proportion of dead unionids) was strongly correlated with Dreissena field density at densities above 1000/m2. Models predicted that severe unionid mortality (>90%) occured when Dreissena density and mean infestation intensity reach 6000/m2 and 100 dreissenids/unionid. Extirpation of unionid populations will occur within 4-5 years after Dreissena establishment at these densities. |
