Study Finds Complexities in Wolf-Elk Interactions Across Greater Yellowstone Ecosystem

Wildlife watching is a major factor in regional tourism, and accounts for much of the industry’s economic benefit across northwestern Wyoming. But as people stop and gather to watch an elk herd graze or a wolf pack chase down prey, the animals are often observing the humans as well. Can the mere presence of humans affect the predator-prey relationship between wolves and elk? Continue Reading →

Thermal imaging offers high-tech look at disease among Yellowstone wolves

Thermal imaging reveals a bright blue patch near the shoulder of a captive wolf, whose fur was shaved to simulate the effects of sarcoptic mange.

A high-tech method for detecting disease in domestic cattle is helping researchers in Yellowstone National Park learn more about how sarcoptic mange effects gray wolf survival and behavior during the park's long, cold winters. For Paul Cross, a wildlife biologist with the U.S. Geological Survey, a moment of insight came when he learned how thermal imaging was used in the cattle industry to detect cows infected with foot-and-mouth disease. The heat-sensitive cameras can pick up on the heat caused by related inflammation in a cow's hoof within a day or two of contracting the disease. Heat-sensing videocameras could help show the metabolic costs of mange in specific wolves, Ross realized. Continue Reading →

Yellowstone Science Conference looks beyond boundaries for answers

The 12th Biennial Scientific Conference on the Greater Yellowstone Ecosystem is being held over three days this week at Mammoth Hot Springs Hotel, centered on a theme of "Crossing Boundaries." But judging from some of the comments during Tuesday's panel discussions and coffee breaks, it seemed like the conference itself had at times crossed a boundary from the world of esoteric hypotheses posed by cautious researchers into a realm of eager discovery and engaged debate by journalists, advocates and members of the general public.

Wyoming Game and Fish to trap wolves east of Yellowstone for monitoring

A male wolf from the Canyon Pack in Yellowstone National Park crosses the Yellowstone River in pursuit of bison.

The Wyoming Game and Fish Department will be trapping wolves east of Yellowstone National Park in the coming months as part of efforts to monitor populations since the animals were proposed for removal from the endangered species list. As part of its ongoing efforts, Wyoming Game and Fish may conduct scientific trapping operations in several locations during the next few months. Continue Reading →

Study: Yellowstone elk pregnancies stressed from poor nutrition, not wolves

A University of Wyoming study shows that elk don’t respond frequently enough to threats from wolves to impact body fat and pregnancy rates. Wolves’ effects on elk populations is limited to direct predation, not harassment or stress that leads to lower pregnancy rates or poor body composition, according to the study. Continue Reading →

Feds move to end protection for gray wolves

Federal wildlife officials on Friday moved to permanently shift responsibility for managing gray wolves to the states, proposing removal of the animals from the list of threatened and endangered species. The U.S. Fish and Wildlife Service said the proposal comes after a comprehensive review has confirmed the successful recovery of gray wolves in the Western Great Lakes and Northern Rocky Mountains.

Wyoming wildlife official says wolves unlikely to thrive outside state’s northwestern corner

A male wolf from the Canyon Pack stands in shallow water in Yellowstone National Park.

After nearly two decades since their reintroduction in Yellowstone National Park, population trends show that gray wolves are unlikely to thrive in sections of Wyoming outside the northwestern corner of the state. Many wolf supporters remain dissatisfied with Wyoming's so-called "dual status" management approach, which classifies wolves as trophy game in the area around Yellowstone and as predators elsewhere. But a state wildlife official said Thursday that policy changes won't have much effect on wolf numbers across most of the state. Continue Reading →
