From overlooking to concealed: predator avoidance in an apex carnivore

Many prey species select bed sites that reduce the risk of being caught off guard. We investigated bed sites used by an apex predator (gray wolf, Canis lupus) before and after individuals were approached by humans (N048 trials). On 9 … read more

How do YouTube videos impact tolerance of wolves?

The internet serves as a dominant source of information and may shape tolerance of wildlife species. Our experimental study examined how respondents’ tolerance for wolves (i.e., attitudes, acceptance, and behavior) changed after viewing wolf related YouTube videos. Respondents were randomly … read more

Stable isotopes, ecological integration and environmental change: wolves record atmospheric carbon isotope trend better than tree rings

Large-scale patterns of isotope ratios are detectable in the tissues of organisms, but the variability in these patterns often obscures detection of environmental trends. We show that plants and animals at lower trophic levels are relatively poor indicators of the … read more

Outsized effect of predation: Wolves alter wetland creation and recolonization by killing ecosystem engineers

Gray wolves are a premier example of how predators can transform ecosystems through trophic cascades. However, whether wolves change ecosystems as drastically as previously suggested has been increasingly questioned. We demonstrate how wolves alter wetland creation and recolonization by killing … read more

Population responses of common ravens to reintroduced gray wolves

Top predators have cascading effects throughout the food web, but their impacts on scavenger abundance are largely unknown. Gray wolves (Canis lupus) provide carrion to a suite of scavenger species, including the common raven (Corvus corax). Ravens are wide‐ranging and … read more

Wolves without borders: Transboundary survival of wolves in Banff National Park over three decades

Large carnivores are important ecological drivers of ecosystem dynamics when they occur at ecologically effective densities. They are also challenging to conserve, especially in transboundary settings such as along borders of parks and protected areas. Here, we tested for effects … read more
