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 ...
The wolf is the largest wild extant member of the family Canidae, and is further distinguished from other Canis species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller Canis species, such as the coyote and the golden jackal, to produce fertile hybrids ...
The Temperament and Character Inventory (TCI) is an inventory for personality traits devised by Cloninger et al. [1] It is closely related to and an outgrowth of the Tridimensional Personality Questionnaire (TPQ), and it has also been related to the dimensions of personality in Zuckerman's alternative five and Eysenck's models [2] and those of the five factor model.
It demonstrated the existence of personality traits in animals and provided a foundation for similar assessment strategies in future studies of personality in animals. [8] Similarly, zebrafish have been used as a neurobehavioral model species for studying personality using the trait approach in non-human animals. These studies can then be ...
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).

Clinical lycanthropy is a rare psychiatric syndrome that involves a delusion that the affected person can transform into, has transformed into, or is a non-human animal. [1] Its name is associated with the mythical condition of lycanthropy , a supernatural affliction in which humans are said to physically shapeshift into wolves. [ 2 ]
In 2021, a mitochondrial DNA analysis of North American wolf-like canines indicates that the extinct Late Pleistocene Beringian wolf was the ancestor of the southern wolf clade, which includes the Mexican wolf and the Great Plains wolf. The Mexican wolf is the most ancestral of the gray wolves that live in North America today. [17]
The only time at which the wolf migrates is during the wintertime when there is complete darkness for 24 hours. This makes Arctic wolf movement hard to research. About 2,250 km (1,400 mi) south of the High Arctic, a wolf movement study took place in the wintertime in complete darkness, when the temperature was as low as −53 °C (−63 °F).
