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 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. Ancestral effective population size estimates indicate a founder event in McKay's buntings followed by an expansion and then a reduction in effective size. Rising sea levels and asymmetric hybridization from McKay's buntings into the postglacially-colonizing population of snow buntings could account for this reduction. Reproductive isolation is likely maintained through differential arrival dates on breeding grounds and the high breeding density of McKay's buntings. This recent, high-latitude divergence best fits a model of founder event speciation driven by vicariance and oscillations in habitat due to climate change.

Data from: Phylogenetic signal in mitochondrial and nuclear markers in sea anemones (Cnidaria, Actiniaria)

The mitochondrial genome of basal animals is generally more slowly evolving than that of bilaterians. This difference in rate complicates the study of relationships among members of these lineages and the discovery of cryptic species or the testing of morphological species concepts within them. We explore the properties of mitochondrial and nuclear ribosomal genes in the cnidarian order Actiniaria, using both an ordinal-scale and familyfamilial-scale sample of taxa. Although the markers do not show significant incongruence, they differ in their phylogenetic informativeness and the kinds of relationships they resolve. Among the markers studied here, the fragments of 12S rDNA and 18S rDNA most effectively recover well-supported nodes; those of 16S rDNA and 28S rDNA are less effective. The general patterns we observed are similar to those in other hexacorallians, although Actiniaria alone show saturation of transitions for orderordinal-scale analyses.
