ABSTRACT

Two distinct lineages of American pine marten (Martes americana) have been identified based on morphology and the mitochondrial cytochrome b gene. Both lineages (western = "caurina", eastern = "americana") probably colonized Southeast Alaska since the last glacial advance and may be in secondary contact in the region. Based on mitochondrial data (N>500), the two lineages are allopatric in Southeast Alaska with the exception of Kuiu Island. Nuclear microsatellite data (18 populations, 7 loci) provide an independent perspective on colonization history. Diagnostic alleles at two microsatellite loci support lineages identified by mitochondrial sequence and suggest a history of interbreeding. Both mitochondrial lineages apparently existed on two islands adjacent to Kuiu Island, but only one lineage remains. The "caurina" lineage may have been displaced recently. These data exemplify the need for nuclear and mitochondrial perspectives to examine the dynamics of intraspecific differentiation.
