Diversity and demography in Beringia: multilocus tests of paleodistribution models reveal the complex history of arctic ground squirrels.

Evolution; international journal of organic evolution - 1 Jul 2011

Abstract excerpt

To assess effects of historical climate change on northern species, we quantified the population history of the arctic ground squirrel (Spermophilus parryii), an arctic-adapted rodent that evolved in Beringia and was strongly influenced by climatic oscillations of the Quaternary. Competing hypotheses for the species' population history were derived from patterns of mitochondrial (mtDNA) structure and a...
