The HSM for Polish wolves predicted with high accuracy the areas later occupied by wolf groups in the western part of the country. A similar approach may also be useful to predict the future distribution of wolves in the lowlands … read more

For many of Yellowstone’s species, spring’s arrival not only brings relief from winter’s challenges, but also resets the biological calendar that governs individuals’ lives. As April’s temperatures rise and its expanding daylight weakens the veneer of snow and ice, many … read more

Distinguishing between coyotes, wolves, and dogs. Wolf pups in mid-summer and fall can closely resemble coyotes, and it can be nearly impossible to tell them apart. Distinguishing dogs from wolves can be challenging. Many of the traits possessed by wolves can … read more

We attempted to cross-foster four 18-19 week-old Gray Wolf (Canis lupus) pups into another Wolf pack 182 km from their natal pack territory. The pup introduction was the result of depredation control on a farm in northwestern Wisconsin. Three pups … read more

Top predators can suppress mesopredators by killing them, competing for resources and instilling fear, but it is unclear how suppression of mesopredators varies with the distribution and abundance of top predators at large spatial scales and among different ecological contexts. … read more

Trophic interactions are a fundamental topic in ecology, but we know little about how competition between apex predators affects predation, the mechanism driving top-down forcing in ecosystems. We used long-term datasets from Scandinavia (Europe) and Yellowstone National Park (North America) … read more
