Which specific North American subspecies is described as one of the largest extant wolf populations?
Answer
Northwestern wolf (*Canis lupus occidentalis*).
The species *Canis lupus* exhibits remarkable geographical variation leading to various subspecies, some of which are ecologically distinct. Among the key recognized North American forms, the Northwestern wolf, scientifically designated as *Canis lupus occidentalis*, is specifically noted for being one of the largest remaining populations of extant wolves. This contrasts with other forms like the Mexican wolf, which is noted for being smaller and ecologically distinct, or the Eurasian wolf, which is geographically separated across Europe and Asia.
