Piping Plovers Losing Breeding Habitat to Wetland Drainage

Released: 11/19/2015 11:30:00 AM
Piping plovers, a federally threatened species of shorebirds, are likely losing wetland breeding habitat in the Great Plains as a result of wetland drainage, climate change or both, according to a new U.S. Geological Survey study.

US Topo Maps Reach Milestone

Released: 11/19/2015 9:30:00 AM
With the release of new US Topo maps for Illinois and South Dakota, the USGS has completed the second, three-year cycle of revising and updating electronic US Topo quadrangles. This means that since late 2009, the USGS has published nearly every map in the conterminous U.S., twice.

Estimates of Undiscovered Copper in Middle East Ten Times Current World Production

Released: 11/18/2015 10:00:00 AM
More than 180 million metric tons of undiscovered copper resources may be found in an area of the Middle East that covers Turkey, Georgia, Armenia, Azerbaijan, Iran, western Pakistan and southwestern Afghanistan, according to a recent assessment by the U.S. Geological Survey.

Collect Points - Get The Patch

Released: 11/18/2015 9:00:00 AM
Using crowdsourcing techniques, the USGS project known as The National Map Corps (TNMCorps) encourages volunteer “citizen scientists” to collect manmade structure data such as police stations, schools, hospitals and cemeteries, in an effort to provide more precise and authoritative spatial data for the USGS web-based mapping portal known as The National Map.

Cause of Deadly Disease in Snakes Identified

Released: 11/17/2015 10:00:00 AM
The fungus Ophidiomyces ophiodiicola is the definitive cause of the skin infections in snakes known as snake fungal disease, or SFD, according to U.S. Geological Survey research published today in the journal mBio.

Arctic Tundra Fire Causes Widespread Permafrost Landscape Changes

Released: 11/12/2015 1:00:00 PM
Large and severe tundra fires cause top down permafrost thaw, playing a major role in altering Arctic landscapes according to a new study led by the U.S. Geological Survey.

Las Vegas Holds Key to Abrupt Climate Change

Released: 11/9/2015 3:00:00 PM
According to new U.S. Geological Survey research published today in the Proceedings of the National Academy of Sciences USA, springs and marshes in the desert outside Las Vegas expanded and contracted dramatically in response to past episodes of abrupt climate change, even disappearing altogether for centuries at a time when conditions became too warm.

Newly Released Photo Catalog Puts US Landscapes On Exhibit

Released: 11/9/2015 12:30:00 PM
The U.S. Geological Survey announced today that it has made part of a huge national repository of geographically referenced USGS field photographs publicly available.

Removing Nitrogen from Groundwater Has New Ally: Anammox

Released: 11/5/2015 1:40:02 PM
USGS scientists have conducted the first-ever field measurements of anammox activity in groundwater, demonstrating that nitrogen removal from groundwater can occur through the action of naturally occurring bacteria.

Native Bees Foraging in Fields Are Exposed to Neonicotinoid Insecticides and other Pesticides

Released: 11/4/2015 11:30:00 AM
According to the first-ever study of pesticide residues on field-caught bees, native bees are exposed to neonicotinoid insecticides and other pesticides.

Acid Rain Effects on Forest Soils begin to Reverse

Released: 11/4/2015 10:00:00 AM
Soil acidification from acid rain that is harmful to plant and aquatic life has now begun to reverse in forests of the northeastern United States and eastern Canada, according to an American-Canadian collaboration of five institutions led by the U.S. Geological Survey.

New Tool Rates Stream Vulnerability to Unconventional Oil and Gas Development

Released: 11/3/2015 1:00:00 PM
On average, streams in the Niobrara-Mowry Play of eastern Wyoming, Fayetteville Play of Arkansas, and Barnett Play of Texas ranked most vulnerable to unconventional oil and gas development, but for different reasons, according to recent U.S. Geological Survey coauthored research.

Genetic Study Confirms Growth of Yellowstone Grizzly Bear Population

Released: 10/30/2015 1:00:00 PM
Genetic data show the grizzly bear population in the Greater Yellowstone Ecosystem has grown since the 1980s with no loss in genetic diversity, according to a report by the Interagency Grizzly Bear Study Team.

Invasive Northern Snakehead Carries Bacteria as Bad as its Bite

Released: 10/29/2015 1:11:26 PM
The invasive northern snakehead fish found in the mid-Atlantic area is now cause for more concern, potentially bringing diseases into the region that may spread to native fish and wildlife, according to a team of U.S. Geological Survey scientists.

U.S. Rivers Show Few Signs of Improvement from Historic Nitrate Increases

Released: 10/28/2015 11:21:02 AM
During 1945 to 1980, nitrate levels in large U.S. rivers increased up to fivefold in intensively managed agricultural areas of the Midwest, according to a new U.S. Geological Survey study.

Everglades' Alligator Numbers Drop after Dry Years

Released: 10/28/2015 8:04:58 AM
Alligators and the Everglades go hand-in-hand, and as water conditions change in the greater Everglades ecosystem, gators are one of the key species that could be affected.

Getting Recognized for Volunteer Mapping Efforts

Released: 10/27/2015 9:30:00 AM
Volunteers are being recognized and earning custom badges for making significant contributions to the U.S. Geological Survey's ability to provide accurate and timely information to the public.

Ancient Permafrost Quickly Transforms to Carbon Dioxide upon Thaw

Released: 10/26/2015 3:00:00 PM
Researchers from the U.S. Geological Survey and key academic partners have quantified how rapidly ancient permafrost decomposes upon thawing and how much carbon dioxide is produced in the process.

Uncovering the Mighty Mississippi's Natural Potential for Nitrogen Removal

Released: 10/26/2015 2:52:04 PM
Working throughout the Mississippi River basin, USGS scientists and collaborators from the University of Texas at Austin have established the river’s own potential to decrease its load of nitrate and identified how certain basic river management practices could increase that potential.
