The Labrador wolf (Canis lupus labradorius) is a possible subspecies of gray wolf native to Labrador and northern Quebec. It has been described as ranging in color from dark, grizzly gray to almost white,[3] and of being closely related to C. l. beothucus.[4]
As of 2005,[5] it is considered a valid subspecies by MSW3, though it is classed as a synonym of C. l. nubilus by the United States Fish and Wildlife Service.[6]
History
Because of over-hunting in the early 1900s, the frequency of C. l. beothucus being spotted was considerably low up through the 1950s. Around that time period, the caribou population began to increase at a steady rate, which then correlated with an increase in the wolf population. However, the increase in number of the Labrador wolf was not enough to offset the continuing rise in caribou in the region, causing a reconsideration of the predation limitation hypothesis.[7]
In the late 2000s and early 2010s, there were several confirmed and unconfirmed sightings of C. l. beothucus on the island of Newfoundland which was surprising since the native wolf was hunted to extinction.[8] In March 2012, a hunter shot and killed a large canine on the Bonavista Peninsula, thinking it to be a coyote; genetic testing found it to be C. l. beothucus.[8] In July 2012, a video posted on YouTube showed a canine which exhibited nearly all characteristics of a wolf. The video was taken in Clode Sound, Terra Nova National Park, and was captured using a motion-sensitive trail camera set up as part of a joint research project on coastal river otters.[9] On 23 August 2012, the Newfoundland and Labrador Department of Environment and Conservation published the results of genetic testing of a large canine trapped on the Baie Verte Peninsula in 2009, confirming that this animal was also C. l. beothucus.[10]
