R. Nowak, N.E. Federoff
1996, Book chapter, Proceedings, Defenders of Wildlife's wolves of America conference, 14-16 November 1996, Albany, NY
Cranial morphology of Recent wolves throughout northern and western North America is remarkably consistent. Statistical analysis indicates the presence of four subspecies of gray wolf (Canis lupus) there, which are always distinguishable from the sympatric coyote (C. latrans). A fifth gray wolf subspecies, lycaon, occurs in southeastern Canada,...
