Humans drive spatial variation in mortality risk for a threatened wolf population in a Canis hybrid zone

Posted on March 9, 2024

Large carnivores often exhibit high survival rates in protected areas, whereas intentional and unintentional human-caused mortality may be greater in adjacent areas. These patterns can result in source-sink dynamics and limit population expansion beyond protected areas. We used telemetry data … read more

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

Germany's wild wolf population has grown, with 209 confirmed packstinyurl.com/3d2c2dvsThe number of wild wolf packs confirmed in Germany has risen to 209, according to new figures from the country's Federal Agency for Nature Conservation (BfN) published on Tuesday.In total, 1,601 individual wolves were detected across Germany during the monitoring year, which lasted from May 1, 2023 to April 30, 2024.In the previous monitoring period from 2022 to 2023, the nationwide number of wolf packs was 184.The report said the bodies of 193 wolves were found dead during the monitoring period, and most of them - 150 - were killed in traffic accidents.Thirteen wolves were intentionally killed illegally during the period.The BfN also said that five wolves "were removed as part of management measures," but did not provide further details about the removals. ...

On Wolves and Deertinyurl.com/38pm7awcFirst to clarify, a wolf pack uses my property on a regular basis. I have been driven out of the woods by mosquitoes, black flies and ticks but never a wolf.I have heard wolves howl and bark. I have seen them, found their territorial markings and they have bedded down in my field. I do not carry a gun when walking my trails. I am only armed with knowledge. I am also a dog owner. I don’t turn her loose on a busy highway and I don’t let her chase wildlife.There is an inherent risk to hunting with dogs. Nearly all the dogs killed by wolves were in pursuit of game, mostly bear, released into known wolf pack territories. Even though DNR makes “caution areas” widely known, hunters continue to release dogs into those areas.The relationship between the wolf and deer is complex and the deer population is not primarily driven by the wolf population or wolf predation.Winter weather, habitat and overall fitness play a role in deer being successful in avoiding the wolf or the wolf will be successful in capturing its prey. An open field clear of snow will give the advantage to the deer who can outrun the wolf; whereas deer can get bogged down in deep snows giving the advantage to the wolf that, with its large, “snowshoe” paws, can walk on top.The publication (Factors Limiting Deer Abundance in the UP) explained that nearly 70% of wolf predations of adult does occurred in late winter and spring when body condition of deer was poorest. Nearly half of the adult does killed by wolves in the high snowfall zone were in such poor condition that they would have likely died even if not preyed upon. The report further states, “Predation from wolves is simply one portion of what impacts our deer herd in the Upper Peninsula, they are not solely responsible for the variation.”The relationship between wolves and deer are intricately linked each having a strong influence on the other’s survival. But, along with adequate prey, wolves also need human tolerance to thrive.photo: John E. Marriott Wildlife and Nature Photography ... See MoreSee Less
