Data from: Diversification at high latitudes: speciation of buntings in the genus Plectrophenax inferred from mitochondrial and nuclear markers
High-latitude diversification is a process characterized by speciation and extinction due to climatically driven vicariance and dispersal events. McKay's buntings (Plectrophenax hyperboreus) are high-latitude island endemic songbirds, and their global range is restricted to Beringia. Snow bunti...

High-latitude diversification is a process characterized by speciation and extinction due to climatically driven vicariance and dispersal events. McKay's buntings (Plectrophenax hyperboreus) are high-latitude island endemic songbirds, and their global range is restricted to Beringia. Snow buntings (P. nivalis), their closest relatives, are distributed throughout the Holarctic, breeding in available habitat surrounding the island range of McKay's buntings. We sequenced 1123 base pairs of mitochondrial DNA for 40 individuals of each species and analyzed a total of 913 AFLPs for 57 individuals. Both marker types suggested weak but significant genetic differentiation. Analysis of sequence data indicated divergence occurring when the current breeding range of McKay's buntings was a hill on the Beringian steppe (~18,400 to ~73,700 years before present), suggesting that snow buntings were restricted to lower latitudes by ice sheets.
