Bozeman - A new U.S. Geological Survey study illustrates the usefulness of genetic approaches to track invasive bullfrog introductions. Results will inform management actions for identifying and controlling importation and secondary spread of invasive bullfrogs in Montana.  

MISSOULA – Gravel-bed river floodplains are some of the most ecologically important habitats in North America, according to a new study by scientists from the U.S. and Canada. Their research shows how broad valleys coming out of glaciated mountains provide highly productive and important habitat for a large diversity of aquatic, avian and terrestrial species.

The U.S. Geological Survey and its partners have shown how brucellosis has impacted cattle, bison and elk in the greater Yellowstone area.

Our transitional site includes the new usgs.gov and more than 180 top-level pages (Mission Areas, Programs, Regions, our three new Science Center websites, Products, Connect, About, etc.). We will migrate more USGS websites into this new experience; check back often to see our progress.

During winter, wolves infected with mange can suffer a substantial amount of heat loss compared to those without the disease, according to a study by the U.S. Geological Survey and its partners.

BOZEMAN, Mont. – 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.

The term crepuscular describes events relating to, resembling, or occurring during twilight, meaning morning and evening hours. An animal described as crepuscular is active during twilight.

A new paper led by U.S. Geological Survey Ecologists Erik Beever (Northern Rocky Mountain Science Center) and Michelle Staudinger (Northeast Climate Science Center) addresses the importance of including adaptive capacity of species as a fundamental component when assessing vulnerability to rapid climate change.

Scientists have discovered that the diversity of a threatened native trout species will likely decrease due to future climate change. 

The type of precipitation falling from the sky matters, especially for delicate mountain ecosystems.
