The Role of Wolves in Regulating a Chronic Non-communicable Disease, Osteoarthritis, in Prey Populations

Posted on May 5, 2022

It is widely accepted that predators disproportionately prey on individuals that are old, weak, diseased or injured. By selectively removing individuals with diseases, predators may play an important role in regulating the overall health of prey populations. However, that idea … read more

Wildlife supporter elated upon hearing news of wandering gray wolf. ( LTE)tinyurl.com/mw6xpf8bYour article on Asha, the wandering gray wolf of eastern Arizona, gave my heart hopeful wings. I am a longtime supporter and volunteer of the Grand Canyon Wolf Recovery Project, here in Flagstaff, and this is a huge step forward in learning all that Asha has to teach us.It’s been a long time coming.Author Rick McIntyre gave us (humans) so much insight into the wolves of Yellowstone in his trilogy of books that start with "The Rise of Wolf 8." His research is from decades of research from the beginning of the reintroduction of wolves to Yellowstone in 1995. Now after thousands of letters, meetings, forums, gatherings and documentaries, we Arizona wolf supporters are seeing our local newspaper headlines ‘Managers have no plans to capture wandering gray wolf’!Photo: Mark Newman ...

Animal welfare advocates file lawsuit challenging Wisconsin's new wolf management plantinyurl.com/mb8384vAnimal welfare advocates filed a lawsuit Wednesday seeking to invalidate Wisconsin’s new wolf management plan, accusing state wildlife officials of violating the state’s open meetings law and disregarding comments from wolf researchers and supporters.The lawsuit reflects how contentious the debate over wolf management has become in Wisconsin. Farmers in northern Wisconsin have complained for years that the population is multiplying too quickly and preying on their livestock. Hunters argue wolves are devastating the deer population across the northern reaches of the state. Conservationists believe that wolves have yet to firmly establish themselves in Wisconsin and need protection.The Great Lakes Wildlife Alliance, also known as Friends of the Wisconsin Wolf and Wildlife, filed the latest lawsuit in Dane County Circuit Court. The organization describes itself as a statewide group of hunters, farmers, politicians, business owners and animal welfare advocates who support science-based conservation.The lawsuit alleges that Department of Natural Resources policy board members collected comments on the plan from interest groups it favored even after the public comment period ended in February.Board members attended private discussions hosted by the Wisconsin Wildlife Federation, the Wisconsin Association of Sporting Dogs, and Wisconsin Wolf Facts in February, April and July, the lawsuit alleges. Great Lakes Wildlife Alliance members were not allowed at the April and July meetings, according to the lawsuit. The filing does not say if members were barred from the February meeting.The lawsuit alleges that even though a quorum of board members didn’t attend any of the meetings, enough of them participated to influence changes to the plan. Adam Payne, the department secretary at the time, announced revisions were coming after the February talks with the organizations that favor further limiting the wolf population. That all amounts to violating open meetings statutes, according to the lawsuit.photo: John E. Marriott Wildlife and Nature Photography ... See MoreSee Less
