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.

The presence of non-native plant species is significantly greater adjacent to oil well pads than in non-developed areas of the Williston Basin, according to a first-of-its-kind U.S. Geological Survey study for this area.

The persistence of an already rare aquatic insect, the western glacier stonefly, is being imperiled by the loss of glaciers and increased stream temperatures due to climate warming in mountain ecosystems, according to a new study released in Freshwater Science.

The American bullfrog has expanded its invasion of the Yellowstone River floodplain in Montana, according to a new study released in “Aquatic Invasions.”

Scientists have discovered that the rapid spread of hybridization between a native species and an invasive species of trout in the wild is strongly linked to changes in climate.

Migratory birds provide ecosystem benefits that include pest control, pollination of plants and serve as food sources for other wildlife.  They are also a source of recreation for millions of bird watchers and enthusiasts who provide food and design backyard habitats to attract a variety of species throughout the year.
