About the Pacific Marten
The Pacific marten (Martes caurina) is a species of North American mammal, a member of the family Mustelidae. It is found throughout western North America. The species was formerly considered conspecific with the American marten (M. americana), but several studies using molecular genetics indicate that M. caurina is a distinct species from it, and it has since been recognized as such by the American Society of Mammalogists. The two species also have some morphological differences, with M. caurina having a shorter rostrum and a broader cranial shape. The two species are thought to have diverged during the Last Glacial Maximum after being isolated from one another in glacial refugia.
Seven subspecies have been recognized based on fossil history, cranial analysis, and mitochondrial DNA analysis. None of the subspecies are separable based on morphology, and subspecies taxonomy is usually ignored except with regards to conservation issues centered around subspecies rather than ranges.
