post-glacial colonization of northwestern north america by the forest-associated american marten (martes americana, mammalia: carnivora: mustelidae).phylogeographic patterns were used to assess intraspecific diversification of american martens (martes americana). within martens, two morphological groups (americana and caurina) have been recognized, though the level of distinction between them has been debated. we examined mitochondrial cytochrome b gene haplotypes from 680 martens to explore the colonization history of the pacific northwest and found two clades that correspond to the morphological groups. the widespread americana clade exten ...200212296948
american marten (martes americana) in the pacific northwest: population differentiation across a landscape fragmented in time and space.american marten (martes americana) have a close association with mature temperate forests, a habitat that expanded throughout the pacific northwest as glaciers receded at the end of the pleistocene. similar to several other forest-associated mammals in north america (e.g. black bear), genetic analysis of the marten shows a deep phylogeographical subdivision that reflects populations with distinctive evolutionary histories. using a suite of 14 microsatellite markers, we explored the genetic struc ...200312492880
