Northwestern wolves are one of the largest subspecies of wolves. In British Columbia, Canada, five adult females averaged 42.5 kg or 93.6 lbs with a range of 85 lbs to 100 lbs (38.6 - 45.4 kg) and ten adult males averaged 112.2 lbs or 51.7 kg with a range of 105 lbs to 135 lbs (47.6 - 61.2 kg), with a weight range for all adults of 38.6 kg to 61.2 kg (85 – 135 lbs).

The wolf inflicted puncture wounds in both legs and a laceration in one. Wanamaker was able to take shelter in an outhouse until the wolf left. She made her way to another outhouse and awakened campers sleeping nearby, who assisted her. Wolf biologist Mark McNay speculated that human-habituation and the wolf's young age were key factors in the ...
Two wolf subspecies that live in the northern Rocky Mountains: Canis lupus irremotus (left) and Canis lupus occidentalis (right) The northern Rocky Mountain wolf preys primarily on the bison, elk, the Rocky Mountain mule deer, and the beaver, though it is an opportunistic animal and will prey upon other species if the chance arises.
The red wolf is an enigmatic taxon, of which there are two proposals over its origin. One is that the red wolf is a distinct species (C. rufus) that has undergone human-influenced admixture with coyotes. The other is that it was never a distinct species but was derived from past admixture between coyotes and gray wolves, due to the gray wolf ...
Wolf distribution is the species distribution of the wolf (Canis lupus). Originally, wolves occurred in Eurasia above the 12th parallel north and in North America above the 15th parallel north. However, deliberate human persecution has reduced the species' range to about one-third, because of livestock predation and fear of wolf attacks on humans
Until the wolves returned, Yellowstone National Park had one of the densest and most stable coyote populations in America due to a lack of human impacts. Two years after the wolf reintroductions, the pre-wolf population of coyotes had been reduced to 50% through both competitive exclusion and intraguild predation. Coyote numbers were 39% lower ...
Elliot distinguishes this wolf by the teeth in both jaws being large and heavy, and along with the skull exceed those of C. l. occidentalis (the Northwestern wolf) of a comparable body size. This wolf's coat ranges from black to white or a mix of both. [2] In 1944, the American zoologist Edward Goldman recognized this wolf as Canis lupus ...
[69] During the late Middle Pleistocene around 600,000 years ago, the Bohemian wolf diversified into two wolf lineages that specialized for different environmental and climatic conditions. One was a southern interglacial (warm climate) grey wolf of Europe which was to become the Mosbach wolf, and the other a northern glacial white wolf of ...
