Eastern wolf

The eastern wolf (Canis lycaon or Canis lupus lycaon), also known as the Eastern Canadian wolf, Eastern Timber wolf, Eastern Canadian red wolf, Algonquin wolf or deer wolf,[2][3] is a canid native to the northeastern side of North America's Great Lakes region as well as southeastern Canada.[4] It is a medium-sized canid which, like the red wolf, is intermediate in size between the coyote and the gray wolf. It primarily preys on white-tailed deer, but may occasionally attack moose and beavers.[5][6] They also prey on muskrats and mice.[7]
The eastern wolf's taxonomic classification has been under review beginning c. 2000, with various suggestions having been presented as to its derivation, including its being a subspecies of gray wolf,[1] its being conspecific with the red wolf,[8][9] gray wolf–coyote hybridization,[10][11] and classification as a separate species within Canis.[8][12] The eastern wolf is recognized as a gray wolf subspecies by Mammal Species of the World (as of 2005).[1] In 2013, following a comprehensive review of several genetic studies, this wolf is proposed to be a distinct species by United States Fish and Wildlife Service.
The eastern wolf is currently listed as a threatened species under COSEWIC and with the Committee on the Status of Species at Risk in Ontario (COSSARO), because "new genetic analyses indicate that the eastern wolf is not a subspecies of grey wolf" versus earlier theories that it was a result of hybridization with both gray wolves and coyotes.[2] The eastern wolf is particularly susceptible to hybridization, due to its close relationship to the coyote and its ability to bridge gene flow between both coyotes and gray wolves. Furthermore, human persecution over a period of 400 years caused a population decline which reduced the number of suitable mates, thus facilitating coyote gene swamping into the eastern wolf population. Aside from posing a threat to a unique species, the resulting eastern wolf–coyote hybrids are too small in size to substitute pure eastern wolves as apex predators of moose and deer. The main nucleus of pure eastern wolves is currently concentrated within Algonquin Provincial Park, eastern Ontario and south central Quebec.[13] However, a 2016 study concluded that even these eastern wolves have about 32% coyote ancestry.[11][14]
