Newswise — Often touted as the greatest environmental achievement of the 20th century, the North American Model of Wildlife Conservation is anything but, say wildlife ecologists and environmental ethicists from Michigan Technological University and Michigan State University.

 It’s an issue that crops up wherever humans and big predators — wolves, bears, lions — coexist.

 Big Wildlife, a non-profit conservation group working to protect predators throughout the west, commissioned, and has now released a special report to evaluate current predator management policies.

Wolves and bears in Yellowstone National Park squabble over elk carcasses, but the two species have little impact on each other’s overall population, a park biologist said last week.

 According to a story posted on Mexicanwolves.org, 1293 scientists sent a letter to Congress expressing their concern that there are legislative attacks on the Endangered Species Act.

 There’s a new kid in town — or at least there was — among the long-studied wolves of Lake Superior’s Isle Royal, where biologist called him “The Old, Gray Guy.”

An Associated Press report reveals that researchers found evidence that ancient Mexicans crossbred wolves and dogs.

A new article which appeared on Scientific American’s web site explores techniques which would make livestock far less appealing to Mexican gray wolves.

Two Mexican Gray wolves arrived at the Wolf Haven International wolf sanctuary, further improving the chances of success with their captive breeding program.

Wolves in the northern Rocky Mountains are genetically healthy and have migrated and bred successfully among subpopulations in central Idaho, greater Yellowstone and northern Montana, according to a new study.
