The lost genetic legacy of American gray wolves
A new study undertaken by researchers at UCLA, Uppsala University and National Museum of Natural History, Smithsonian Institution and published in the journal Molecular Ecology, suggests that plans to reintroduce American gray wolves to the Western US will not restore the population to the near same extent of genetic diversity it originally... view more...

Who's afraid of the big, bad wolf? Coyotes
While the wily coyote reigns as top dog in much of the country, it leads a nervous existence wherever it coexists with its larger relative, the wolf, according to a new study from the Wildlife Conservation Society. view more (2007-09-12)
Researchers determine why wolves not dispersing as fast as expected in Yellowstone
In 1995, 14 wolves were transferred to Yellowstone National Park in the U.S. from the Canadian Rocky Mountains, with 17 more joining them the following year. view more (2006-11-02)
Gray wolves feed the masses while hunters feed the few
Gray wolves (Canis lupus) and human hunters both provide resource subsidies to scavengers in Yellowstone National Park, USA, by provisioning them with the remains of their kills. Carrion from wolf versus hunter kills is much more dispersed in both time and space. In the November issue of Ecology Letters, scientists from Berkeley and Yellowstone... view more... (2003-10-08)
Wolves would rather eat salmon
Although most people imagine wolves chasing deer and other hoofed animals, new research suggests that, when they can, wolves actually prefer fishing to hunting. view more (2008-09-02)
Wolves lose their predatory edge in mid-life, new U of Minnesota study shows
Although most wolves in Yellowstone National Park live to be nearly six years old, their ability to kill prey peaks when they are two to three, according to a study led by Dan MacNulty and recently published online by Ecology Letters. view more (2009-10-27)
Iberian wolves prefer wild roe deer to domestic animals
A Spanish researcher has analysed the preferences of wolves from the north east of the Iberian Peninsula to demonstrate that, in reality, their favourite prey are roe deer, deer and wild boar, ahead of domestic ruminants (sheep, goats, cows and horses). view more (2009-10-26)
Are wolves the pronghorn's best friend?
As western states debate removing the gray wolf from protection under the Endangered Species Act, a new study by the Wildlife Conservation Society cautions that doing so may result in an unintended decline in another species: the pronghorn, a uniquely North American animal that resembles an African antelope. view more (2008-03-04)
Prey not hard-wired to fear predators
Are Asian elk hard-wired to fear the Siberian tigers who stalk them" When wolves disappear from the forest, are moose still afraid of them? view more (2007-06-21)
Dog's place and date of birth identified
Earlier studies of this field have shown that Eastern Asia is the place where the wolf was tamed to become the dog. view more (2009-09-01)
Killing wolves may not protect livestock efficiently
Costly and time-consuming efforts to eliminate wolves that prey on sheep, cattle and other domestic animals are ineffective on a long-term, regional scale, according to an examination of wolf control methods in Alberta and several U.S. states by University of Calgary researchers. view more (2006-04-05)
Bone Deformities Linked to Inbreeding in Wolves of Isle Royale
The wolves on Isle Royale are suffering from genetically deformed bones. Scientists from Michigan Technological University blame the extreme inbreeding of the small, isolated wolf population at the island National Park in northern Lake Superior. view more (2009-04-03)
Wolves, moose and biodiversity: An unexpected connection
Moose eat plants; wolves kill moose. What difference does this classic predator-prey interaction make to biodiversity? view more (2009-11-02)
Greater Yellowstone elk suffer worse nutrition and lower birth rates due to wolves
Wolves have caused elk in the Greater Yellowstone Ecosystem to change their behavior and foraging habits so much so that herds are having fewer calves, mainly due to changes in their nutrition. view more (2009-07-20)
Loss of top predators causing surge in smaller predators, ecosystem collapse
The catastrophic decline around the world of "apex" predators such as wolves, cougars, lions or sharks has led to a huge increase in smaller "mesopredators" that are causing major economic and ecological disruptions, a new study concludes. view more (2009-10-02)
Biologists solve mystery of black wolves
Why do nearly half of North American wolves have black coats while European wolves are overwhelmingly gray or white? The surprising answer, according to teams of biologists and molecular geneticists from Stanford University, UCLA, Sweden, Canada and Italy, is that the black coats are the result of historical matings between black dogs and wild... view more...

Wolf reintroduction proposed in Scottish Highland test case
Researchers are proposing in a new report that a major experiment be conducted to reintroduce wolves to a test site in the Scottish Highlands, to help control the populations and behavior of red deer that in the past 250 years have changed the whole nature of large ecosystems. view more (2009-07-21)
BETWEEN THE WOLF AND THE DOG
The dog was the first animal domesticated by human beings. However, domestication took more than one step: people and dogs used to adjust to each other within numerous generations of coexistence. Biochemical and genetic researches have proved quite definitely that the dog's ancestor was the big predatory wolf, but not its smaller relative - the... view more... (2003-04-25)
Presence of wolves allows aspen recovery in Yellowstone
The wolves are back, and for the first time in more than 50 years, young aspen trees are growing again in the northern range of Yellowstone National Park. view more (2007-07-27)
A new take on why social cues confuse babies and dogs in a classic hiding game
A study by developmental scientists at the University of Iowa and Indiana University challenges the conclusions of two recent studies on how babies and dogs respond to certain social cues. view more (2009-09-25)
