Four species of the Mustela, Martes zibellina (sable), Martes americana (American marten), Martes martes (pine marten), and Martes melampus (Japanese marten) are forest-dwelling carnivores that occur allopatrically in coniferous and deciduous forests in the Holarctic region (Ishida et al., 2013).
In contrast, in the ecological specialization through reproductive interference model, genetic divergence (speciation) occurs allopatrically and reproductive interference promotes habitat differentiation when the two already distinct species come into secondary contact [49, 50].
Burford (2009) concluded that the 2 lineages speciated allopatrically much earlier than the LGM and that they have subsequently expanded ranges to form an area of sympatry from central Oregon to northern California.
Detailed investigations, such as those of the present study, are revealing associations between sex-linked inversions, potential past mating trials and incipient speciation that has probably given rise to the currently allopatrically distributed and reproductively isolated species, S.
