Phylogeography and mitochondrial DNA (mtDNA) diversity in North American collared lemmings ( Dicrostonyx groenlandicus)
Abstract Variation in the nucleotide sequence of the mitochondrial control region (250 bp) and the cytochrome b region (870 bp) was examined in collared lemmings ( Dicrostonyx groenlandicus ) from 19 localities in northern Alaska and the Canadian Arctic. The division of D. groenlandicus in two phylo...
