www.werc.usgs.gov — Mercury is a contaminant of significant concern in waterbirds because it can accumulate to high concentrations in their tissues and cause deleterious effects such as impaired reproduction. Numerous studies and monitoring programs have evaluated concentrations of mercury in waterbird tissues as an index of risk to exposure. However, no single More...

fl.biology.usgs.gov — The Nile tilapia (Oreochromis niloticus) is commonly used in aquaculture worldwide. Feral populations exist in many regions where individuals escape culture and establish in natural habitats. In Mississippi, Nile tilapia are established in at least three distinct localities (fig. 1): the lower Pascagoula and Escatawpa river drainages, and a 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 — There are approximately 500,000 abandoned mines in the western US. Collectively, these mines pollute rivers, streams, and western reservoirs with millions of tons of metals annually that degrade aquatic habitat and water used by humans for drinking, recreation, and irrigation. However, there is great potential in decreasing or eliminating the flow More...
