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.fort.usgs.gov — This report provides a preliminary review of adaptation options for climate-sensitive ecosystems and resources in the United States. The term "adaptation" in this document refers to adjustments in human social systems (e.g., management) in response to climate stimuli and their effects. Since management always occurs in the context of desired More...

fl.biology.usgs.gov — This website is an overview and species profile of the The New Zealand mudsnail (Potamopyrgus antipodarum), which is a small aquatic snail. As its name states, this species is native to freshwater lakes and streams of New Zealand. Like many organisms today, it is being incidentally carried to many locations around the world such as Europe, Asia, More...

www.umesc.usgs.gov — This report is about native freshwater mussels of the Upper Mississippi River System. In the United States, 69 of 304 mussel species are listed as federally endangered or threatened. Surveys conducted over the past few decades have documented significant declines in mussel populations across the continent. Among the factors thought to be More...

www.lsc.usgs.gov — Freshwater bivalves, which are among the most threatened animals in North America, present significant challenges to conservation biologists that attempt to maintain ecological and evolutionary processes within and among populations. Effective management of this rare fauna is often complicated because inadequate information exists for 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 — 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...

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...
