Resources ≀ Predator/Prey Relationships

Population declines were documented in multiple ruminant species in Montana and surrounding states starting in 1995. While weather, food sources, and predation certainly contributed, the declines were often attributed, at least partly, to unexplained factors. Use of teratogenic agrichemicals, notably … read more

There is much debate regarding the role wolves have on deer populations and deer hunting in particular. Many have stated that wolves are “decimating” the deer population in Minnesota and that we need to kill wolves to resolve this issue. … read more

Recolonization of predators to their former ranges is becoming increasingly prevalent. Such recolonization places predators among their prey once again; the latter having lived without predation (from such predators) for a considerable time. This renewed coexistence creates opportunities to explore … read more

Humans are increasingly recognized as important players in predator–prey dynamics by modifying landscapes. This trend has been well-documented for large mammal communities in North American boreal forests: logging creates early seral forests that benefit ungulates such as white-tailed deer (Odocoileus … read more

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

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
