Alient hunters went berserk after NASA released a photo showing what could be a possible fossilized grizzly bear or a sloth-like creature. Does life on Mars really exist?
Its mother frantically tried to save her fatally injured cub by dragging it to the side of the road, but to no avail. Roadkills in national parks are now a growing concern.
Advanced solar-powered tracking devices allow researchers to follow previously hard-to-study animals as they feed, socialize or migrate. In turn, this data could be used to make better wildlife and habitat management decisions.
With the help of detection dogs, researchers have located areas within the Greater Yellowstone Ecosystem that may be suitable for grizzly bear habitats. This will allow researchers to better target conservation measures.
Yellowstone National Park's Iconic grizzly bears may soon lose their protection under the Endangered Species Act (ESA) but not if Native American Tribes have their way.
More and more endangered grizzly bears are frequenting the southeastern part of the Greater Yellowstone ecosystem every summer, according to a recent study, in search of army cutworm moths.

Grizzly bears are making a comeback in Yellowstone National Park, according to a recent assessment of the threatened beasts. And this recovery has a lot to do with the fact that fewer grizzlies are dying in and around the park. Now officials are even considering lifting protections for the hardy animal.
Researchers studying grizzly bears, which are clearly obese animals, have discovered a natural state of diabetes that serves a real biological purpose and is also reversible, according to a new study.
In a rather unusual study, a group of indigenous people has mapped out a "grizzly highway" that stretches hundreds of miles through British Colombia, shedding light on bear populations in the area.
No, wolves are not sidling up to a friendly grizzly bear to offer a bushel of berries, but they are helping in their own way. Researchers have found that recovering wolf populations in North America are culling elk numbers, leaving more berries for sweet-toothed grizzlies to munch on.
