Results 181 - 190 of 203 listed by similarity [list alphabetically]

The whooping crane report [More info]: Report on the captive breeding program at Patuxent Wildlife Research Center to help save endangered whooping cranes. Site links to natural history information on whooping cranes, why they are endangered, cool facts on cranes, and a photo gallery.
Three Experimental High-Flow Releases from Glen Canyon Dam, Arizona-Effects on the Downstream Colorado River Ecosystem [More info]: Scientific issues we should consider when conduction high flow experiments to ameliorate the negative effects of dams on native river species and fluvial processes.
Understanding beach health throughout the Great Lakes -- Continuing research [More info]: Outlines tactical problems that make it difficult for beach managers to use scientific information to make beach closure and advisory decisions. Explains methodologies we are using to address those problems and better prepare local decision makers.
Understanding beach health throughout the Great Lakes-Entering a new era of investigations [More info]: People who manage recreational areas need better, more timely estimates of the likelihood that the beach and lake waters will be hazardous to human health, and which factors cause those hazards.
Understanding the habitat needs of the declining western yellow-billed cuckoo [More info]: This endangered species prefers native trees in large, continuous areas of riparian habitat. Armed with this information, resource managers may identify and preserve areas favorable to this population.
United States Geological Survey fire science--Fire danger monitoring and forecasting [More info]: We use moderate resolution satellite data to assess live fuel condition for estimating fire danger. Using 23 years of vegetation condition measurements, we are able to determine the relative greenness of wildland vegetation susceptible to burning.
Upper Mississippi River fish and macroinvertebrate data [More info]: Interactive databases providing detailed information on fish and macroinvertebrate abundance and diversity over time in pools of the upper Mississippi River basin.
Urban development results in stressors that degrade stream ecosystems [More info]: Explains which aspects of stream ecosystems are harmed by urban development and how, along with implications for those who manage urban ecosystems.
USGS recreation site: your science gateway for safe and vital enjoyment of the outdoors [More info]: Gateway to useful USGS websites for recreation in nature watching and exploring, boating, camping, climbing, fishing, hiking, biking, and hunting, with links to maps, real-time streamflow, geology, photos, and plant and animal information.
USGS St. Petersburg Coastal and Marine Science Center--Research activities in the U.S. Virgin Islands [More info]: Explains type of information we collect and the problems we study in this area, focusing on coral reef ecosystems, ocean acidification, and sea-level change.
