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

Effects of Wolf Mortality on Livestock Depredations

Predator control and sport hunting are often used to reduce predator populations and livestock depredations, – but the efficacy of lethal control has rarely been tested. We assessed the effects of wolf mortality on reducing livestock depredations in Idaho, Montana … read more

How Long Do Anti-Predator Interventions Remain Effective? Patterns, Thresholds and Uncertainty

Human–predator conflicts are globally widespread, and effective interventions are essential to protect human assets from predator attacks. As effectiveness also has a temporal dimension, it is of importance to know how long interventions remain most effective and to determine time … 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
