Grizzly bears feast on diverse diet
02-14-2007 · EurekAlert!There's no such thing as picky grizzly bears -- they'll eat almost anything they can find. A new University of Alberta study that tracked food habits of the Alberta grizzly bear living in the foothills sheds some light on the animal's varied diet and their activity pattern.

- Study of bear hair will reveal genetic diversity of Yellowstone's grizzlies
12-18-2007 · EurekAlert!
Montana State University's library of 400 grizzly bear hair samples will be analyzed to determine the genetic diversity of the Greater Yellowstone Ecosystem population. The study will also determine if bears from the Northern Continental Divide Ecosystem are adding their genetic diversity to the Yellowstone group.

- MU researchers to study the status of black bears in Missouri
06-13-2007 · EurekAlert!
Researchers at the University of Missouri-Columbia are studying the status of black bears in Missouri. Black bears were abundant in the state during the 18th and 19th centuries, but have been considered almost extinct in Missouri since the late 19th century. The results of the MU study will be used by the Missouri Department of Conservation to help manage Missouri's black bear population.

- Varied diet of early hominid casts doubt on extinction theory, says Colorado U. study
11-09-2006 · EurekAlert!
An upright hominid that lived side by side with direct ancestors of modern humans more than a million years ago had a far more diverse diet than once believed, clouding the notion that it was driven to extinction by its picky eating habits as the African continent dried, says a new University of Colorado at Boulder study.

- Bear hunting altered genetics more than Ice Age isolation
11-23-2007 · EurekAlert!
It was not the isolation of the Ice Age that determined the genetic distribution of bears, as has long been thought. This is shown by an international research team led from Uppsala University in Sweden in the latest issue of Molecular Ecology. One possible interpretation is that the hunting of bears by humans and human land use have been crucial factors.

- How stress alleviates pain
12-05-2007 · EurekAlert!
One way to alleviate the pain of banging your shin while on a hike is to encounter a grizzly bear -- a well-known phenomenon called stress-induced analgesia. Now, researchers have elucidated a key mechanism by which the stress hormone noradrenaline -- which floods the bloodstream during grizzly encounters and other stressful events -- affects the brain's pain-processing pathway to produce such analgesia. Pankaj Sah and colleagues published their findings in the Dec. 6, 2007, issue of the journal Neuron, published by Cell Press.

- The bear necessities of aging
12-11-2007 · EurekAlert!
According to George Bernard Shaw: "We don't stop playing because we grow old; we grow old because we stop playing." But how fast does that aging occur once started? In the case of populations of salmon in Alaska studied by Stephanie Carlson and colleagues at the University of Washington and McGill University and reported on in this week's PLoS ONE, it all depends on how choosy are the bears which feed on them.

- Does natural selection drive the evolution of cancer?
11-17-2006 · EurekAlert!
The dynamics of evolution are fully in play within the environment of a tumor, just as they are in forests and meadows, oceans and streams. This is the view of researchers in an emerging cross-disciplinary field that brings the thinking of ecologists and evolutionary biologists to bear on cancer biology. Insights from their work may have profound implications for understanding why current cancer therapies often fail and how radically new therapies might be devised.

- Earth's soils bear unmistakable footprints of humans
01-25-2008 · EurekAlert!
The dirt under our feet is being so changed by humans that it is now appropriate to call this the "Anthropocene (or man-made) Age," says a new worldwide overview by Duke University soil scientist Daniel Richter.
