2689 Dreissena polymorpha Habitat Alteration Observational Field There appears to have been no adverse impacts of zebra mussel on walleye reproduction in western Lake Erie during 1990 and 1991. Lake Erie 9007
2783 Dreissena polymorpha Habitat Alteration Experimental Laboratory Zebra mussel populations living on soft sediments significantly reduced the foraging efficiencies of all fish and crayfish predators. 20370
2850 Dreissena polymorpha Habitat Alteration Experimental Laboratory The increase in complexity of bottom habitat provided by zebra mussels caused an increase in amphipods. Predation by bluegill (Lepomis macrochirus) fish on amphipods was decreased by this complex habitat the mussels provide. Lake Erie 20579
2976 Dreissena polymorpha Habitat Alteration Observational Field After the arrival of the zebra mussel, water clarity increased chlorophyll a decreased. Decreases were also seen in numbers of native bivalves and polychaetes. Gammarid amphipods and tubificid worms were unchanged. Lake Erie 22627
3025 Dreissena polymorpha Habitat Alteration Observational Field Zebra mussels have the capacity to reduce turbidity to allow submersed macrophytes such as Vallisneria americana to increase expand their distribution and relative abundance. Lake Huron 23033
3104 Dreissena polymorpha Habitat Alteration Observational Field Densities of some benthic organisms such as Amphipoda and Gastropoda have increased in shallow waters due to modification of light penetration by zebra mussels. Oneida Lake, New York 23399
3114 Dreissena polymorpha Habitat Alteration Observational Field Zebra mussels attached to dragonfly larvae causing them to bury more slowly and not as deep into the substrate, possibly making the larvae subject to predation. Douglas Lake, Michigan 27106
3117 Dreissena polymorpha Habitat Alteration Experimental Laboratory Zebra mussels may enhance the establishment, spread, and potential impacts of invasive crayfish where they are found together. 32046
3458 Dreissena polymorpha Habitat Alteration Anecdotal Field Native plants Najas guadalupensis and Elodea canadensis, and the submersed annuals, Potamogeton foliosus, P. pusillus var. pusillus, and Najas flexilis returned likely due to the water clarity brought about by the introduction of non-native zebra and quagga mussels. Lake Erie 10476
3460 Dreissena polymorpha Habitat Alteration Anecdotal Field The nonative Myriophyllum spicatum, Potamogeton crispus, and the submersed form of Butomus umbellatus decreased likely due to the water clarity brought on by the introduction of zebra mussels and quagga mussels. Lake Erie 10476
6395 Dreissena polymorpha Habitat Alteration Anecdotal N/A Presence of Dreissena polymorpha in Storm Lake had led to an increase in water clarity. 41888
6428 Dreissena polymorpha Habitat Alteration Observational Field Dreissena polymorpha filter particles from the water, resulting in increased light availability, resulting in increased nuisance algal and plant growth. Lough Neagh, Northern Ireland, United Kingdom 41925
7388 Dreissena polymorpha Habitat Alteration Anecdotal N/A Dreissena polymorpha beds change the substrate structure, which provide more colonization area for gastropods, amphipods and many other benthic taxa. 42296
7395 Dreissena polymorpha Habitat Alteration Observational Field Colonies of Dreissena polymorpha hinder the spawning of Salvelinus namaycush. 42296
8282 Dreissena polymorpha Habitat Alteration Observational Field In Lake Erie, the rate of biosedimentation through pseudofeces production was very high (28mg/cm2 day at a density of 1180 individuals/m2) under turbid conditions, lending support to the hypothesis that zebra mussels (Dreissena polymorpha) are responsible for increased water clarity observed since mussel introduction. Lake Erie, USA 13802
8283 Dreissena polymorpha Habitat Alteration Anecdotal N/A Increased water clarity from Dreissena polymorpha allows light to penetrate further, potentially promoting macrophyte populations. 24608
8284 Dreissena polymorpha Habitat Alteration Observational Field Increasing amounts of pseudofeces and biodeposits could also have an impact on multiple trophic levels via changes to the physical environment. A current study in Brocton Shoal, Lake Erie, suggests that colonization of lakebed areas by dreissenid mussels (Dreissena polymorpha) and the consequent filling of remaining interstitial spaces with pseudofeces and fine-grained sediments may significantly eliminate valuable habitat native habitat . Brocton Shoal, once thought to be an important area for lake trout spawning, has diminished suitability as a spawning ground. Brocton Shoal, Lake Erie 13790
