Is There A Mechanism That Causes Wolves from Same Area to Disperse Long-distances in Same Direction?

Posted on January 29, 2020

Dispersal is a fundamental component of the ecology of most animal populations. Dispersing individuals typically leave their natal habitat in search of a mate or available resources such as food and space (Gotelli 2008). Grey wolves (Canis lupus) typically disperse … read more

Fear of Large Carnivores Causes a Trophic Cascade

Posted on July 6, 2019

The fear large carnivores inspire, independent of their direct killing of prey, may itself cause cascading effects down food webs potentially critical for conserving ecosystem function, particularly by affecting large herbivores and mesocarnivores. However, the evidence of this has been … 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? ...
