Plague [ More info] History, pathology, and prospects for this historic disease that is still prevalent in animals and remains a threat to humans.
Streamflow of 2011 - Water Year Summary [ More info] A broad survey of regional patterns in stream flow nationwide. Maps and graphs summarizing streamflow conditions for water-year 2011 (October 1, 2010 to September 30, 2011) in the context of the 82-year period 1930-2011.
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.
Net Ecosystem Production (NEP) of the Great Plains, United States [ More info] Geographic analysis of the changes in storage and release of carbon in this large area as land use patterns, especially agriculture, have changed.
Mapping, monitoring, and modeling Western Gateway Community landscape dynamics [ More info] Geospatial analysis of factors affecting communities that are adjacent to Federal lands, especially those lands subject to varying public interest and visitation.
USGS National Map of Surficial Mineralogy [ More info] Maps of exposed surface mineral groups derived from automated spectral analysis of satellite and airborne imaging systems; these data suggest areas that may contain mineral deposits of various types.
Priority ecosystem studies initiative [ More info] Description of the priority ecosystems studies initiative with links to projects in Chesapeake Bay, Greater Yellowstone, Mojave Desert, Platte River, Salton Sea, San Francisco, and south Florida.
Mercury Concentrations in Streams Found to Go Through Daily Cycles [ More info] Research findings and examples of application to real problems--highly variable conditions cause the production of toxic methyl mercury in the environment which accumulates in fish.
Geospatial Multi-Agency Coordination (GeoMAC) wildland fire perimeters, 2008 [ More info] Where the fires were, as GIS data in shapefile format, geographic coordinates, NAD83.
Noninvasive methods for monitoring bear population trends [ More info] We estimate population growth rates by collecting hair at natural bear rubs along trails, roads, and fence and power lines, and analyzing the DNA from the hair.
