However, the divergence was a much greater 8.0% between gray wolf (C. lupus) mtDNA and eastern/red wolf haplotypes, and 10.0% between gray wolf and coyote haplotypes. The sequence difference observed between eastern Canadian wolf sequences and coyote sequences is consistent with a separation of 150 000 – 300 000 years, using a divergence rate ...
The Eurasian wolf (Canis lupus lupus), also known as the common wolf, [3] is a subspecies of grey wolf native to Europe and Asia. It was once widespread throughout Eurasia prior to the Middle Ages . Aside from an extensive paleontological record, Indo-European languages typically have several words for "wolf", thus attesting to the animal's ...
The gray wolf was extirpated in Denmark in 1772 and Norway's last wolf was killed in 1973. The species was decimated in 20th century Finland, despite regular dispersals from Russia. The gray wolf was only present in the eastern and northern parts of Finland by 1900, though its numbers increased after World War II. [4]
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).

Since 1973, the gray wolf has been on and off the federal government's endangered species list. When the wolves are on the list, advocates say the protections help wolves' place in the natural ...
Wolf after re-introduction. The history of wolves in Yellowstone includes the extirpation, absence and reintroduction of wild populations of the gray wolf (Canis lupus) to Yellowstone National Park and the Greater Yellowstone Ecosystem. When the park was created in 1872, wolf populations were already in decline in Montana, Wyoming and Idaho.
In 1974 when the gray wolf was officially listed as endangered under the Endangered Species Act, there were only about 750 wolves in the Great Lakes region.Today, it is estimated that there are ...
