Wolf's journey shows value of connectivity

A wolf with a global positioning system device attached to her neck has documented what wildlife biologists have long known: individual wolves often travel long distances when looking for a mate, new hunting prospects, or both. In this case, the wolf, an adult female, traveled 450 kilometers (280 miles) from Jasper National Park before being killed by a trapper near Sheridan Lake, B.C. Even more amazing long-distance trotting was documented in recent years when wolves that originated in the Yellowstone ecosystem wound up in northern Colorado, one just west of Denver and the other near Beaver Creek and Vail. In the latter case, a global positioning device documented a travel of 450 direct miles (724 kilometers), although wildlife biologists estimate the wolf actually covered 1,000 miles. Wolf expert Mark Hebbelwhite told the Rocky Mountain Outlook that such journeys illustrate the importance of connectivity between ecosystems. But in Wyoming's Jackson Hole, exactly the opposite problem was evident. There, three wolves had an affliction called the mange, a parasitic infection of the skin that causes the animal to scratch their hair off, leaving them exposed to the elements. The wolves, federal officials tell the Jackson Hole News&Guide, have been hanging around people's houses. The U.S. Fish and Wildlife Service has issued a permit to the landowner to use rubber bullets to shoot at the animals, in an attempt to drive them off...DailyNews
