nas.er.usgs.gov — This site has been established as a central repository for accurate and spatially referenced biogeographic accounts of nonindigenous aquatic species. The program provides scientific reports, online/realtime queries, spatial data sets, regional contact lists, and general information. The data is made available for use by biologists, interagency More...

www.umesc.usgs.gov — Zebra mussels have caused drastic declines in native clam and mussel populations in some locations. Zebra mussels compete with other invertebrates and young fish for plankton, the primary food source for these groups. UMESC scientists are investigating the effects zebra mussels are having on the riverine ecosystem. This study examines the effects More...

fl.biology.usgs.gov — This resource is a species profile and nonindigenous species information bulletin for the Veined Rapa Whelk, Asian Rapa Whelk, Rapana venosa (Valenciennes, 1846) Mollusca: Gastropoda, Muricidae. The shell is globose (rounded), with a very short-spire and large body whorl. The veined rapa whelks are carnivorous gastropods whose main diet More...

fl.biology.usgs.gov — This web resource is a map representation of the distribution of zebra and quagga mussels in U.S. lakes. Zebra mussels were first detected in 1988 in Lake St. Clair, located between Lake Huron and Lake Erie. Within just a few years, they spread into all five of the Great Lakes. Since then, zebra mussels have spread into many large navigable More...

www.umesc.usgs.gov — The invasion of the exotic zebra mussel (Dreissena polymorpha) into the Upper Mississippi River (UMR) was documented in 1991 with the discovery of a zebra mussel in Pool 8 near La Crosse, Wisconsin. Zebra mussels have expanded their range throughout the UMR because of their high reproductive rate, the free-swimming veliger stage, and ease of More...

fl.biology.usgs.gov — One hundred zebra mussels were collected from a site located near Kentucky Dam in the Kentucky portion of the Tennessee River on 20 April 1997 to study in situ growth rates. Four chambers, each containing 25 individual compartments, were secured to the substrate. A 100 percent survival rate was observed during this study. Initial measurements of More...

fl.biology.usgs.gov — Invasive nonindigenous species are important because they threaten native communities, alter habitats, and can have significant economic impacts. In aquatic environments, invasive species can be especially noxious because native species have few options for escaping direct interactions such as predation and competition for habitat and food. This More...
