Brett Smith for redOrbit.com - Your Universe Online Thanks to 'predator control' practices, wolves were eradicated from Yellowstone National Park in 1926. Their reintroduction in 1995 has shifted the balance of the regional ecosystem and provided an unexpected bonus for the park's grizzly bears. According to a new study in Journal of Animal Ecology, the return of wolves to the park has reduced the elk population, subsequently allowing wild berries to flourish and nourish Yellowstone's...

Trees and the insects that eat them wage constant war. Insects burrow and munch; trees deploy lethal and disruptive defenses in the form of chemicals. But in a warming world, where temperatures and seasonal change are in flux, the tide of battle may be shifting in some insects' favor, according to a new study. In a report published today (Dec. 31, 2012) in the Proceedings of the National Academy of Sciences, a team of scientists from the University of Wisconsin-Madison reports a rising...

A University of Alberta-led research team has determined that the mountain pine beetle has invaded jack pine forests in Alberta, opening up the possibility for an infestation that could stretch across the Prairies and keep moving east towards the Atlantic. A group of U of A tree biologists and geneticists discovered that, as the mountain pine beetle spread eastward from central British Columbia, it successfully jumped species from its main host, the lodgepole pine, to the jack pine. Jack pine...

New study of Clark's nutcrackers suggests that their caching of whitebark pine seeds is less effective than previously thought at restoring populations of the declining conifer The caching of whitebark pine seeds by the Clark's nutcracker in late summer and early fall may not be enough to regenerate populations of the imperiled conifer in most of its range, scientists have found. Their research"”which is featured in the February issue of Science Findings, a monthly publication of the...

If your summer travels have taken you across the Rocky Mountains, you've probably seen large swaths of reddish trees dotting otherwise green forests. While it may look like autumn has come early to the mountains, evergreen trees don't change color with the seasons. The red trees are dying, the result of attacks by mountain pine beetles. Mountain pine beetles are native to western forests, and they have evolved with the trees they infest, such as lodgepole pine and whitebark pine trees....

Bad news for those planning to visit Yellowstone this fall--the favorite food of the park's grizzlies will be in short supply, meaning that the bears will be hungrier and more likely to pursue other sources of protein, according to researchers with the U.S. Geological Survey (USGS). "Pack your bear spray: there's going to be run-ins," Chuck Schwartz of the USGS told Matthew Brown of the Associated Press (AP) on Sunday, noting that the shortage of nuts from whitebark pine cones could lead to...

Yellowstone Grizzly bears are returning to the threatened species list, according to a federal court order on Monday. The grizzly bear species was announced to have rebounded in March 2007, but many are once again threatened by changes in their habitat, primarily in how climate change has rid the region of whitebark pines, which the bears rely on. Judge Donald Molloy issued a 46-page decision on Monday to restore protections for the grizzly bear, which resides primarily in and around the...
