fl.biology.usgs.gov — The African jewelfish (Hemichromis letourneuxi) has been established in canals surrounding the Miami area since the 1960s. With changes in water delivery to the park, the species has recently (2000) entered Everglades National Park and expanded its range westward through Big Cypress National Preserve. Simultaneously, African jewelfish from a 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...

wfrc.usgs.gov — As anadromous juvenile salmonids migrate from freshwater rearing habitats to the ocean, they are vulnerable to a host of factors that affect their survival. Direct effects associated with dam passage (e.g., instantaneous mortality, injury, loss of equilibrium, etc.) and indirect effects (e.g., predation, disease, and physiological stress) More...
