pubs.usgs.gov — Water is among Florida's most valued resources. The State has more than 1,700 streams and rivers, 7,800 freshwater lakes, 700 springs, 11 million acres of wetlands, and underlying aquifers yielding quantities of freshwater necessary for both human and environmental needs (Fernald and Purdum, 1998). Although renewable, these water resources are More...

www.umesc.usgs.gov — The moose population in northwestern Minnesota has been declining for over 25 years. The U.S. Fish and Wildlife Service has identified a need to determine whether the moose decline is a result of nutrition, parasites, disease, contaminants, or a combination of those factors. In an attempt to determine the cause of death for moose in northwestern More...
