coastal.er.usgs.gov — One purpose of the USGS National Assessment of Coastal Change Project is to provide accurate representations of pre-storm ground conditions for areas that are designated high-priority because they have dense populations or valuable resources that are at potential risk from storm waves. Another purpose of the project is to develop a broad More...

alaska.usgs.gov — It is estimated that 100,000-150,000 Bar-tailed Godwits breed in Alaska. Under the US Shorebird Conservation Plan, they are a species of High Concern mainly due to their small population size, threats to their non-breeding grounds (especially at migratory stopover sites in Asia), and their relatively restricted breeding distribution within the More...

alaska.usgs.gov — Rock Sandpipers are a species unique to the north Pacific, with breeding populations found in near-shore habitats ringing the Bering Sea (Gill et al. 2002). Likely numbering fewer than 100,000 individuals and with at least 4 recognized subspecies, this robin-sized shorebird displays physiological feats of wonder by virtue of its being the More...

www.werc.usgs.gov — Sea otters (Enhydra lutris) are keystone predators in the nearshore environment of the eastern Pacific Ocean, in a food web composed of sea otter, sea urchin, and kelp forest. Without sea otters, the kelp forest can be overgrazed by sea urchins, which in turn can affect other species that depend on this ecosystem. This resource provides links to More...

pubs.er.usgs.gov — This report presents the results of the 2006 International Census of Piping Plovers (Charadrius melodus). Two sets of tabular data are reported: one for distribution and abundance of wintering Piping Plovers, the other for distribution and abundance of breeding Piping Plovers. The winter census resulted in the observation of 3,884 Piping Plovers More...

fl.biology.usgs.gov — Because the African jewelfish has a broad salinity tolerance, scientists tested how the species low-temperature tolerance varied at three salinities: freshwater (0 ppt), brackish (10 ppt) and marine (35 ppt) in the laboratory. A field experiment was then conducted to examine the survivorship of individuals when caged in several common aquatic More...

wfrc.usgs.gov — Ballast water discharges are the most significant cause of aquatic biological invasions in coastal waters, including the Great Lakes. Currently, treatment of ballast water prior to discharge at the receiving port offers significant promise to help control this problem. However, development of treatment technologies is limited by lack of objective More...
