Molecular Phylogeny of the Chipmunk Genus Tamias Based on the Mitochondrial Cytochrome Oxidase Subunit II Gene

  • Antoinette J. Piaggio
  • Greg S. Spicer


Complete sequences of the mitochondrial cytochrome oxidase subunit II gene were used to construct a phylogeny for 21 of the 25 currently recognized chipmunk species. Phylogenetic analyses indicate that T. striatus (subgenus Tamias, eastern United States) and T. sibiricus (subgenus Eutamias, Asia) are distantly related to the other species (subgenus Neotamias), which constitute a western North American radiation. We discuss and compare our molecular phylogeny to previous taxonomies and present a suggested classification of the species groups for the subgenus Neotamias.
