By Jennifer Donovan, Michigan Technological University In the Isle Royale Wolf-Moose Study’s annual report released today, the researchers say that over the past three years, they have tallied the lowest numbers of wolves ever: nine in 2011–12, eight in 2012–13 and nine in 2013–14. During the same period, predation rates—the proportion of the moose population killed by wolves—also dropped to the lowest ever recorded, while the number of moose doubled, to approximately 1,050...

Lawrence LeBlond for redOrbit.com Researchers from Michigan Technological University studying the wolf population at Isle Royale National Park were bewildered as to why there was a significant decline in the numbers of wolves on the northwest island on Lake Superior during their 2012 Winter Study -- the population went from 16 to 9 in just one year. After scratching their heads for months over the disappearances, the team received word in May that could explain at least some of the...

It's seen as a sign of getting old, but scientists have discovered that arthritis is not just a human problem as a study lasting 50 years reveals how moose suffer from an identical form of the condition. The research, published in Ecology Letters, also casts new light on how malnutrition early in life can lead to the disorder in both moose and humans. The study, which began in 1958, was carried out on Isle Royale, a wilderness island National Park in lake superior, with only one large...

TRAVERSE CITY, Mich. -- Chased into the Lake Superior shallows, mauled and left for dead by fellow wolves, the young female struggled to shore and collapsed. A lone male came to the rescue, licking her wounds and staying on as she recovered. Together they formed a successful and prolific pack, with the female bearing at least 19 pups. But their love story has ended tragically: A rival pack killed the female this winter, a year after fatally attacking her mate as he munched on a moose...

For campers at Isle Royale National Park, sighting a gray wolf is a rare and thrilling experience. At least, it has been. But some wolves have gotten a bit too familiar this summer, wandering into camping areas and showing little of their customary fear of people. No attacks or threatening behavior have been reported. But the close encounters prompted warnings to visitors not to feed the wolves. "Wolves are wild animals and potentially dangerous like any wild animals," said Michigan Tech...

Rolf Peterson has watched a bleeding female wolf struggle to survive, helped by a turncoat male from the rival pack that had mauled and left her for dead. He has come face to face with a wolf while lying on a forest path shooting video; the animal casually detoured around him. He and his wife have spent three decades of summers in an old fishing cabin without electricity or running water. The nearby storage shed is jammed to the rafters with moose skulls and antlers. And he has chronicled...

TRAVERSE CITY, Mich. -- Gnawing leisurely on the remains of a moose carcass, the wolf pack's alpha male seemed unaware that mortal danger was coming ever closer. Suddenly the eight-member rival pack burst into view. The alpha scrambled to his feet, but too late. Howling and barking, the enemy chased him down and mercilessly attacked, killing the hapless victim within a couple of minutes. It's not unusual for the gray wolves on Isle Royale National Park to target each other, said John...

TRAVERSE CITY, Mich. (AP) -- Mercilessly hounded by blood-sucking ticks, the Isle Royale moose herd is on a downward spiral - and the wolf packs that roam the national park in Lake Superior are taking advantage. The moose population fell to about 540 this winter, down from 740 last year and 1,100 during the winter of 2002-03, wildlife biologist Rolf Peterson of Michigan Tech University said Tuesday. Meanwhile, wolf numbers jumped from 19 to 29 last season and reached 30 this year. Although...
