简介
A previously published phylogeographic analysis of mtDNA sequences from the widespread Palearctic common rosefinch (Carpodacus erythrinus) suggested the existence of three recently diverged groups, corresponding to the Caucasus, central-western Eurasia, and northeastern Eurasia. We re-evaluated the mtDNA data using coalescence methods and added sequence data from a sex-linked gene. The mtDNA gene tree and SAMOVA supported the distinctiveness of the Caucasian group but not the other two groups. However, UPGMA clustering of mtDNA ΦST-values among populations recovered the three groups. The sex-linked gene tree recovered no phylogeographic signal, which was attributed to recent divergence and insufficient time for sorting of alleles. Overall, coalescence methods indicated a lack of gene flow among the three groups, and population expansion in the central-western and …
