Impacts of Zebra Mussels ( Dreissena polymorpha ) on the Benthic Community in Kashong Bay , Seneca Lake , Ontario County , New York : 1992 - 94

چکیده
On July 13, 1992 a team of researchers from the BFS visited Kashong Bay in order to provide a characterization of the benthic community prior to expected impacts by the then recent introduction of the zebra mussel, Dreissena polymorpha (Harman, 1993a). A transect was erected perpendicular to the shoreline from the eulittoral zone (beach) to 25 feet in depth. Inspection by SCUBA was used to collect the necessary information. Data obtained was supplemented by 4 Ekman dredge samples.

Increased benthic algal primary production in response to the invasive zebra mussel (Dreissena polymorpha) in a productive ecosystem, Oneida Lake, New York.
Increased water clarity associated with zebra mussel (Dreissena polymorpha) populations may favor benthic algal primary production in freshwater systems previously dominated by pelagic phytoplankton production. While zebra mussel-mediated water clarity effects on benthic primary production have been implicated in published reports, few production estimates are available. This study estimates be...
متن کاملDreissena polymorpha in Lake Constance: An example of a keystone engineer?
In the last decades, zebra mussels (Dreissena polymorpha) have invaded many freshwater systems with severe consequences for entire communities. Most benthic macroinvertebrates, especially amphipods and chironomids, increase in abundance in the presence of zebra mussels. Increased structural complexity and an unknown biotic factor lead to this effect. Dreissena-associated factors that might infl...

Concentrations of particulate and dissolved nutrients in Saginaw Bay, Lake Huron, were examined relative to zebra mussel colonization which occurred summer 1991. The magnitude and spatial pattern of changes indicate that mussels had a significant impact on nutrients in Saginaw Bay. Annual means for total suspended solids, particulate organic carbon, particulate phosphorus, and particulate silic...

Surveys of the benthic macroinvertebrate community were conducted in the main basin of Lake Huron in 2000 and 2003, and in Georgian Bay and North Channel in 2002. Results were compared to surveys conducted in the 1960s and early 1970s. Although data of earlier surveys were inconsistent, our best estimates suggest that total density of the four major benthic taxa (Diporeia spp., Oligochaeta, Sph...
