Wolves use their urine to communicate with each other. A recent study looked at the reactions of a pack to the marking of an intruder. This is a first step toward understanding what attracts or repels canids.

Over 30 years ago, federal wildlife managers reintroduced wolves to Yellowstone National Park — and the canines began dining on elk, culling the population, leaving less wapiti to browse on aspens, willows and cottonwoods.
In the years since, observers of the Greater Yellowstone Ecosystem have likely heard some version of a commonly held belief: Wolf reintroduction reduced over browsing and helped those trees rebound. Scientists call that process a “trophic cascade,” jargon for a ripple effect down the food chain.
But, since the early 2000s, researchers studying forestry in Yellowstone have disagreed about and debated the magnitude of that effect, and whether reintroduction has, in fact, helped aspens rebound to the extent the public believes.

Lifelong trapper Wesley Burris makes a bold claim: His father trapped and killed the last remaining lobo in New Mexico in the 1930s, around the time the subspecies was wiped out in the state.
Burris said his family has been ranching around the San Mateo Mountains since the early 19th century, with as many as 3,000 head of cattle at one time.
“They had lots of trouble with wolves and mountain lions and bears,” Burris said. “That’s where my people was raised. … Back then there was no fences, there was no nothing. It was wide open country.”

A group that opposes Colorado’s wolf reintroduction efforts is now arguing that Proposition 114, the ballot initiative that established the state’s wolf reintroduction program, didn’t actually pass among voters in 2020.
The group, Colorado Conservation Alliance, is asking the U.S. Fish and Wildlife Service — which is already reviewing the reintroduction program — to reconsider the implementation agreement it has with Colorado Parks and Wildlife while these claims are reviewed.

Wolf urine could be used as a scent barrier to protect livestock from attack, according to Swiss researchers. Urine gives wolves important information about potential intruders. Alpha wolves with pups are particularly alert to this, as a study by the University of Neuchâtel shows.

Wisconsin’s wolf population fell slightly this year, according to estimates from the Department of Natural Resources.
The department has been monitoring the number of wolves in the state since the 1970s by surveying snow-covered roads for tracks and other signs.

Collbran resident Christina Vander Berg had a 25-year career investigating fires and built a life as a Western Slope cattle producer and rodeo judge.
Over the past two years, she’s stepped into a new role that draws on her passions and experience: serving as a range rider amid Colorado’s controversial wolf reintroduction.

Three apex predators (snow leopards, common leopards, and Himalayan wolves) coexist in a remote valley in Nepal’s central Himalayas by relying on different food sources.
Researchers analyzed six years of camera-trap footage and fecal DNA from the Lapchi Valley to discover that snow leopards eat mainly wild ungulates, leopards feed on livestock and animals near human settlements, and wolves eat a mix of both.

The Indian Grey Wolf was once common across India’s grasslands and semi-arid regions, and its discovery in the Amrabad landscape is an important conservation milestone that underscores the ecological value of the tiger reserve, officials said.

In Yellowstone National Park, a network of recorders listens day and night. The devices capture thousands of wolf howls drifting across the valleys.
That audio now feeds artificial intelligence models built to do something no one has done before. The goal is to identify individual wolves by the unique signature of their voices.
The International Wolf Center uses science-based education to teach and inspire the world about wolves, their ecology, and the wolf-human relationship.
