Wolves alter the trajectory of forests by shaping the central place foraging behaviour of an ecosystem engineer

Predators can directly and indirectly alter the foraging behaviour of prey through direct predation and the risk of predation, and in doing so, initiate indirect effects that influence myriad species and ecological processes. We describe how wolves indirectly alter the … read more

Factors Limiting Deer Abundance in the Upper Peninsula

In the Upper Peninsula of Michigan, there are numerous factors that may act singularly or in combination to influence deer abundance. For instance, if food availability was greatly reduced, especially during critical times, or habitat that is essential for survival … read more

Recovery of a marine keystone predator transforms terrestrial predator–prey dynamics

Sea otters (Enhydra lutris) and wolves (Canis lupus) are two apex predators with strong and cascading effects on ecosystem structure and function. After decades of recovery from near extirpation, their ranges now overlap, allowing sea otters and wolves to interact … read more

Interspecific Killing of Vulpes vulpes (Red Fox) Kits at a Den Site by Canis lupus (Gray Wolf) in Isle Royale National Park, Michigan

Canis lupus (Gray Wolf or Wolf) have killed subordinate canids that scavenge on Wolfkilled prey, but little evidence is available for antagonistic behavior of Wolves toward other canids at interspecific den sites. We investigated clusters of locations from a global … read more

Indigenous-led conservation: Pathways to recovery for the nearly extirpated Klinse-Za mountain caribou

Indigenous Peoples around the northern hemisphere have long relied on caribou for subsistence and for ceremonial and community purposes. Unfortunately, despite recovery efforts by federal and provincial agencies, caribou are currently in decline in many areas across Canada. In response … read more

Habitat loss accelerates for the endangered woodland caribou in western Canada

Habitat loss is often the ultimate cause of species endangerment and is also a leading factor inhibiting species recovery. For this reason, species-at-risk legislation, policies and plans typically focus on habitat conservation and restoration as mechanisms for recovery. To assess … read more
