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

Caribou encounters with wolves increase near roads and trails: a time-to-event approach

Posted on October 27, 2020

Caribou and reindeer Rangifer tarandus are declining across North America and Scandinavia in part from wolf Canis lupus-mediated apparent competition with more abundant ungulate prey species. While caribou generally persist in areas with low wolf density, wolf packs that overlap … read more

Spatial Responses of Wolves to Roads and Trails in Mountain Valleys

Posted on October 27, 2020

Increasing levels of human activity in mountainous areas have high potential to inhibit animal movement across and among valleys. We examined how wolves respond to roads, trails, and other developments. We recorded the movements of two wolf packs for two … read more

Biologists cross-foster 16 Mexican gray wolf pups into wild denstinyurl.com/2p9u84kaArizona wildlife officials say they’ve introduced 16 captive-born endangered Mexican gray wolf pups to wild dens.The newborn pups were placed within 14 days of being born and bred at four facilities across the U.S.The Arizona Game and Fish Department says the cross-fostered pups have a 50% survival rate within their first year, the same as wild pups.They were put in five wild dens in New Mexico and one in Arizona with similarly aged wild pups. This is a very tediousprocess of flying the pups to their states, along with the representatives of the centers and it’s done at nite. “Under darkness we place you in a new home and we must fool your new mother” The smells must be the same or familiar to mom and that’s beyond this Wolfwatcher knowledge. The people workingsneak the pups in and nestle them among the families, new barns. The magic word is “Tiptoe” a way into the nite and and we got it done.Though numbers of Mexican wolves in the wild are at their highest ever level, a lack of genetic diversity continues to hamper the program.Wolfwatcher does not have an inside scoop,but I assumeEndangered Wolf Center; California Wolf Center; Wolf Conservation Center and the last I believe might be WolfHaven International.Mexican wolf foster parents get it done and we thank them.Photo: Brookfield Zoo,Chicago ...

Activists gathered locally, seeking to 'rewild' Oregontinyurl.com/yjczphnfThere is a movement across the West — indeed, across many parts of the world — to restore ecosystems and bring back the keystone species that used to inhabit them. This movement is called “rewilding.”A rewilding conference last Saturday at Lake Creek Lodge in Camp Sherman focused on initiatives across the state of Oregon.Learning about carnivores and that killing cougars and wolves can increase predation on livestock was valuable information for Marshall.“A lot of people don’t know that. Maybe if they knew they wouldn’t support killing cougars and wolves.photo: Wild Memories by Deby ... See MoreSee Less
