Wolf reintroduction reshapes Yellowstone ecology
The 1995 reintroduction of wolves in the northern range of Yellowstone National Park has led to increased growth of willow and cottonwood in the park by causing fear responses in elk and other ungulates, according to William J. Ripple and Robert L. Beschta of Oregon State University in Corvallis. Ripple and Beschta, writing in the August 2004 issue of BioScience, argue that fear of predation when...Wolves are rebalancing Yellowstone ecosystem
CORVALLIS, Ore. - The reintroduction of wolves into Yellowstone National Park may be the key to maintaining groves of cottonwood trees that were well on their way to localized extinction, and is working to rebalance a stream ecosystem in the park for the first time in seven decades, Oregon State University scientists say in two new studies....

NEW YORK (APRIL 13, 2004) -- Bottlenecks from increased development are choking off ancient migration routes for wildlife in the Greater Yellowstone Ecosystem (GYE) and other regions, according to a study by the New York-based Wildlife Conservation Society (WCS) that appears in the current issue of the journal Conservation Biology.... ...Increased gas development in particular is making it more a...Yellowstone wolves, grizzlies and moose 'dysfunctional' study says
NEW YORK (April 15, 2003) A recent study by the Wildlife Conservation Society (WCS) appearing in the journal Biological Conservation warns that a proposal to remove grizzly bears and wolves living in the Greater Yellowstone Ecosystem (GYE) from the Endangered Species List is premature, because neither species may be fully recovered. ...Federal officials are now moving to delist the largest carni...Lake tributaries in Yellowstone National Park allow unique study of whirling disease
. BOZEMAN, MONT--The tributaries of Yellowstone Lake in Yellowstone National Park remind fisheries biologist Beth MacConnell of the three bears: Some tributaries may be too hot for the parasite that causes whirling disease; some may be too cold, and some might be just right. . Just what temperatures allow the infection to flourish is what MacConnell and other scientists hope to find out in....As people learn to live with grizzly bears and wolves that have recolonized areas around southern Yellowstone National Park after a 50-year absence, so too must moose, which apparently have forgotten to recognize predators, according to a study funded by the Bronx Zoo-based Wildlife Conservation Society (WCS).. .Published in the Feb. 9th issue of the journal Science, the study shows that moose...Scientist searches Yellowstone Park for carbon dioxide-eating microbe

. CHAMPAIGN, Ill. Humans have a penchant for travel driving, sailing and flying over the planet in search of new places to live.
