Group Formation of New Isle Royale Wolves Leads to Territorial Aggression

GPS collar data shows three wolves, 1 female and 2 males, have been traveling, feeding, and bedding together since March, 2019 (W001F, W007M, and W013M). This is the first wolf group to form and remain associated since introduction efforts began… … read more

Michigan DNR said it killed wolves to protect humans

Michigan DNR said it killed wolves to protect humans. Officials at the Michigan Department of Natural Resources and some lawmakers opposed to wolf protection policies were found to have embroidered, misstated or outright fictionalized the threat that gray wolves posed to … read more

Anthropogenic Food Subsidies Hinder The Ecological Role Of Wolves: Insights For Conservation Of Apex Predators In Human-modified Landscapes

In ecologically pristine ecosystems, top-down effects of apex predators play a fundamental role in shaping trophic cascades and structuring ecosystems, but in human-modified landscapes anthropogenic effects may markedly alter the ecological role of predators. In particular, human-provisioned food subsidies represent … read more

Grasshopper Consumption by Grey Wolves and Implications for Ecosystems

The eradication and subsequent reintroduction of grey wolves (Canis lupus) in the western United States has provided unique insights into the role these predators play in regulating ecosystem functioning and dynamics. Although the importance of wolves in ecosystems has been … read more

Tooth Fracture Frequency in Gray Wolves Reflects Prey Availability

Exceptionally high rates of tooth fracture in large Pleistocene carnivorans imply intensified interspecific competition, given that tooth fracture rises with increased bone consumption, a behavior that likely occurs when prey are difficult to acquire. To assess the link between prey … read more

Genomic signatures of extensive inbreeding in Isle Royale wolves, a population on the threshold of extinction

The observation that small isolated populations often suffer reduced fitness from inbreeding depression has guided conservation theory and practice for decades. However, investigating the genome-wide dynamics associated with inbreeding depression in natural populations is only now feasible with relatively inexpensive … read more
