More than thirty subspecies of Canis lupus have been recognized, including the dog and dingo, though gray wolves, as popularly understood, only comprise naturally-occurring wild subspecies.
The New World wolves did not show any gene flow with the boxer, dingo or Chinese indigenous dogs but there was indication of gene flow between the Mexican wolf and the African basenji. [13] All species within the genus Canis, the wolf-like canids, are phylogenetically closely related with 78 chromosomes and can potentially interbreed. [100]
Two gray wolves were captured in north-central Washington state in July 2008, one of which was a nursing female. This was the first evidence of reproducing wolves in the state since the 1930s. [133] As of the end of 2022, Washington has at least 216 wolves in 37 packs with 5 breeding pairs. [134]
The idea of wolf reintroduction was first brought to Congress in 1966 by biologists who were concerned with the critically high elk populations in Yellowstone and the ecological damages to the land from excessively large herds. Officially, 1926 was when the last wolves were killed within Yellowstone’s boundaries.
The Arabian wolf is one of the smallest subspecies of wolf. It stands on average 25–26 inches (64–66 cm) at shoulder height [ 13 ] and the adult weighs an average of 45 pounds (20.41 kg). [ 14 ] The cranial length of the adult Arabian wolf measures on average 200.8 mm (0.659 ft), which is smaller than most wolves. [ 15 ]
Today, wolves have returned to the area. [24] Wolf hunting in France was first institutionalized by Charlemagne between 800 and 813, when he established the louveterie, a special corps of wolf hunters. The louveterie was abolished after the French Revolution in 1789, but was re-established in 1814. In 1883, up to 1,386 wolves were killed, with ...
The Mexican wolf is the most ancestral of the gray wolves that live in North America today. The modern coyote appeared around 10,000 years ago. The most genetically basal coyote mDNA clade pre-dates the Late Glacial Maximum and is a haplotype that can only be found in the Eastern wolf.
The eastern wolf (Canis lycaon[ 5 ] or Canis lupus lycaon[ 6 ][ 7 ]), also known as the timber wolf, [ 8 ]Algonquin wolf and eastern timber wolf, [ 9 ] is a canine of debated taxonomy native to the Great Lakes region and southeastern Canada. It is considered to be either a unique subspecies of gray wolf or red wolf or a separate species from ...
