Welcome to our new and improved comments Published 9:45 p.m. All rights reserved ( Another female, one of the animals taken to Isle Royale beginning in fall 2018, also died in recent months from wounds inflicted by one or more wolves. A necropsy showed it had been attacked by fellow wolves, park officials said in a statement.The fate of the other other island-born wolf, a 10-year-old female, is unknown.“She is the final native wolf, never radio-collared, and searching for her will be a priority” for biologists during their annual winter study at the park, said Rolf Peterson, a research professor at Michigan Technological University.A photo provided by the National Park Service in 2018 shows a 4-year-old female gray wolf emerging from her cage at Isle Royale National Park.

However, the virus that struck the wolves was only exacerbated by the fact that fewer wolves were naturally migrating to the island. Researchers who have been studying the predator-prey dynamics there for decades determined these last two island-born wolves would not be able to make a dent in the moose population.The push for new wolves not only is being done to balance out the moose population by bringing in some large Canadian wolves used to hunting large prey, but to give the island wolves a new infusion of DNA.

Then, GPS showed his movements became limited.Park staff and partners from the Grand Portage Band of Chippewa went to the island to investigate, and found the male wolf’s body. Staff are committed to doing everything possible to protect the lives of all wolves involved in the relocation process.“In the end, even our most dedicated efforts sometimes succumb to the difficult realities of nature.”As of a few years ago, the island’s once-robust wolf packs had dwindled to just two wolves. Isle Royale, the principal island of Isle Royale National Park in Michigan in the United States, is an isolated island with little migration of animals into and out of the island, and as a national park, human interaction and impact on the two species is also limited. Officials said Wednesday the black-coated male's body was found in the middle of a large, swampy area at the southwestern end of the Lake Superior wilderness island. They made adjustments in the length of time captured wolves were kept in the field before they were transported, and re-evaluated how they were sedating the wolves.The female wolf’s necropsy was done at the University of Minnesota Veterinary Diagnostic Lab.Participants in the wolf relocation project surround a crate used to transport a captured wolf to Isle Royale.The second wolf to die in the relocation effort was The post-mortem exam revealed the male wolf died of pneumonia, “... though how the wolf developed this condition is unknown,” park staff said.They said the wolf’s tracking collar - all the relocated wolves are fitted with GPS collars so scientists can track their movements - started showing a mortality signal even though staff could see him moving around on the game cameras.

The second wolf to die in the relocation effort was a male wolf found dead on Isle Royale in late October.
