Heavily Hunted Wolves Have Higher Stress and Reproductive Steroids Than Wolves With Lower Hunting Pressure

Posted on July 2, 2019

Human-caused harassment and mortality (e.g. hunting) affects many aspects of wildlife population dynamics and social structure. Little is known, however, about the social and physiological effects of hunting, which might provide valuable insights into the Mechanisms by which wildlife respond … read more

Environmental and Intrinsic Correlates of Stress in Free-Ranging Wolves

Posted on June 15, 2019

Background: When confronted with a stressor, animals react with several physiological and behavioral responses. Although sustained or repeated stress can result in severe deleterious physiological effects, the causes of stress in free-ranging animals are yet poorly documented. In our study, … read more

The Ecology of Stress: Predator-Induced Stress And the Ecology of Fear

Posted on June 15, 2019

Predator-induced stress has been used to exemplify the concept of stress for close to 100 years. Walter B. Cannon, one of the pioneers of the study of stress, used predatorinduced stress in wildlife in 1915 to exemplify the ‘fight or … read more

Some groups want federal protection for Great Lakes gray wolves dropped as role of Endangered Species Act examinedtinyurl.com/yakmph7dRepublican lawmakers in the U.S. Committee on Natural Resources argued at an oversight meeting that the Endangered Species Act was an overreach of federal authority and an ambiguous statute, as part of a broader reexamination of conservation laws.Federal protection for nearly 50 years has helped gray wolf populations steadily recover, mostly in the Rocky Mountains and western Great Lakes regions. But in the past 20 years, conservationists, hunters, ranchers and politicians have used different definitions of recovery to repeatedly shift the gray wolf on and off the endangered list. At issue is whether the species has recovered enough to be sustainable and how states will regulate hunting.“Wolves have made encouraging progress since they were first protected,” said Amanda Wight, senior program manager for wildlife protection at nonprofit Humane World for Animals, formerly the Humane Society of the United States. “But it’s important to remember that federal protections are still very necessary for wolves. They’re still absent from most of their historic range, as well as most currently suitable habitat. And wolves face many ongoing threats, including climate change, loss of habitat and inadequate regulatory mechanisms by state agencies.”While conservationists and wolf experts emphasize the need for wolves to be present in their historic range to consider them recovered, proponents of delisting say gray wolf populations across the region have sufficiently bounced back.If gray wolves are delisted, Runty said, the main concern among conservationists is that inadequately regulated hunting may significantly hurt their population numbers — and the broader ecosystems.When the species was delisted during windows under Obama and Trump, advocates say states in the Midwest held hunting competitions that turned into “bloodbaths.”“When you’re considering whether or not to remove a species from the Endangered Species Act, I think it’s important to consider: If that protection goes away, is the species likely to go back to what caused it to be endangered in the first place? ...
