The replacement in North America of a basal population of wolves by a more recent one supported the findings of earlier studies. [126] [134] [125] [129] There possibly existed a panmictic wolf population with gene flow spanning Eurasia and North America until the closing of the ice sheets.
Global wolf range based on IUCN's 2023 assessment. [1] The wolf (Canis lupus; [b] pl.: wolves), also known as the gray wolf or grey wolf, is a canine native to Eurasia and North America. More than thirty subspecies of Canis lupus have been recognized, including the dog and dingo, though gray wolves, as popularly understood, only comprise ...
Jun 18, 2024 · The oldest wolf fossils in North America come from a fossil locality in Alaska, which may preserve fossils from one million to 700 000 years old. Wolves underwent multiple waves of immigration into North America, coinciding with glaciations and low sea level, giving rise to modern wolf populations. [Text] What makes wolves so successful?

The wolf is the largest wild member of the dog family. The grey wolf is the largest species, weighing 25–45 kg, and has a distinctively massive head with a strong forehead. It resembles a German shepherd dog, although its coat is usually greyish. Black or almost white individuals also exist; brown may also be present in some of their coats. In Nort...
Before colonization, wolves were common in North America’s forests, tundra and prairies, but are now restricted to wilder northern regions and National Parks. The different subspecies inhabit different regions in Canada. Arctic wolves can be found in the forests and tundra of northern Quebec and the territories. Coastal wolves can be found in the c...
Wolves typically live in packs (usually 3–7). Pack dynamics can be quite complex and have a fluid hierarchy. However, they tend to consist of a dominant male and a dominant female, which are the primary breeding pair. The rest of the pack are often related to the dominant pair, though exact relationships vary. Neighbouring packs also frequently sha...
Breeding starts at about 2–3 years. Litters of about 7 (4–13) pups are born after 63 days gestation. Female wolves whelp (give birth) in a den, either a burrow or natural shelter. The pack protects and brings food to the nursing mother and the growing pups.
Wolves are primarily carnivorous. They will hunt deer, caribou, moose, wapiti and, in summer, smaller game. They will also supplement their carnivorous diets with fruits and berries during certain times of the year. In July, blueberriescan form the majority of the diet of certain wolves.
The genus Canis, of which wolves, coyotes, dogs and foxes are the most familiar forms, derives from the small, fox-sized Miocene (23.7-4.9 million years ago) North American canid Cynodesmus. By Early Pleistocene times (about 1.65 million years ago), Caniswas widespread in North America, Asia and Europe. During the Late Pleistocene, at least 12,000 ...
Globally, the gray wolf is listed as a species of least concern by the IUCN Red List. However, the eastern wolf is listed as Threatened under Canada's Species at Risk Act. The primary threats to wolves are habitat loss and hunting by humans, especially in southern Canada.
Wolves evolved from a common ancestor of the Canidae family around 4-5 million years ago. They were originally small, forest-dwelling creatures but gradually evolved into larger, more versatile animals. Wolves eventually diverged into different subspecies, including gray and red wolves. They spread worldwide, and the environment and human interactions shaped their evolution.
Red wolves are under constant threat of being de-listed from the ESA by political lobbies who claim that it is a mongrel wolf-coyote hybrid rather than a distinct species. De-listing would almost certainly be a death sentence for red wolves. As of October 2020, there were only seven radio-collared wild red wolves known to exist in North Carolina.

Origins and Early History. Wolves, scientifically known as Canis lupus, are one of the most widely distributed land mammals. They are believed to have originated in Eurasia and migrated to North America over a million years ago. Early wolves were larger than modern wolves and likely traversed the land bridge between Siberia and Alaska during ...
