Regional Impacts
| Ecological Impact | Herbivory | |
| Reduction in chlorophyl a and increased light penetration, since the onset of the dreissenid invasions, was also seen in the eastern basin of Lake Erie (North et al. 2012). | ||
| Ecological Impact | Parasite/Predator Vector | |
| Dreissena bugensis was found to be an important host for trematode parasites, inclduing the cosmopolitan Echinoparyphium recurvatum which can cause fatal infections in waterfowl (Karatayev et al. 2012). | ||
