Researchers have also determined that wolves, in the recent absence of hard winters, are now the primary reason for elk mortality. Before wolf reintroduction, deep snows were the main determinant of whether an elk was going to die. 加州大学伯克利分校的研究人员还确定(立论),雪的减少和狼的增多使...
This does give us a long running dataset, spanning decades and enabling us to look at historical changes for wolf populations at Yellowstone.[5] The reintroduction of wolves to Yellowstone has been mostly positive While the true impact of wolves on Yellowstone is still somewhat debated, scientists...
Wolves were too recently reintroduced to Isle Royale to make similar comparisons, but we conclude that intervention is not contrary to the Wilderness Act, nor author Howard Zahniser's vision, partially because wolf reintroduction was a mitigation for human actions. Also, not intervening, or ...
Opponents of the wolf reintroduction claim that wolves chase and weaken elk and other prey animals in the park by running them, and kill just for the fun of it. The video here shows what really happens and that wolves are unsuccessful more than they are successful, and generally go days or...
Researchers have also determined that wolves, in the recent absence of hard winters, are now the primary reason for elk mortality. Before wolf reintroduction, deep snows were the main determinant of whether an elk was going to die. Researchers from the University of California at Berkeley determin...
Ecology is a field of science that studies relationships among all the different things in an environment. In the case of the wolf reintroduction, it’s impossible to say with total certainty that the wolves were theonlyreason that the Yellowstone ecosystem recovered. And even more surprising, it...

It is a fitting tribute to the 100 years plus of research pre and post wolf reintroduction, and a sound basis for future studies."–The Biologist"An intimate look at these wild canines and their ways. Humans have always felt more about wolves than we've actually known about them. ...
The region is one of the last strongholds of American bison, and the reintroduction of the gray wolf in 1995 allows park managers to claim the area as the largest intact ecoregion in the northern temperate zone. The potentially damaging impacts of logging, hunting, and tourism are regulated, ...
This is the first resident group of wolves in the Bechler area since wolf reintroduction began in 1995. Prior to this there was little wolf activity and only occasional reports of tracks. The group consists of a very large dispersing male from the Rose Creek Pack and three uncollared wolves,...
