| Résumé : | The Icelandic Redpoll Carduelis flammea islandica is one of three subspecies of Carduelis flammea. The other two are C. f. rostrata, breeding in Greenland, and C. f. flammea, widely distributed at high latitudes in both North America and Eurasia. Recent studies on variation of the mtDNA control region and microsatellites among C. f. r. and C. f. f. and related species (Arctic Redpoll Carduelis hornemanni and Lesser Redpoll Carduelis cabaret) did not reveal clear genetic differentiation among the species. Here we include DNA sequences of mtDNA and nuclear markers of the Icelandic subspecies (C. f.islandica) and from additional samples of the other species and subspecies to evaluate further their taxonomic status within the complex, with special emphasis on C. f.islandica. Mitochondrial and nuclear variation is large within species and does not provide support for the current subspecies and the species classification. Significant differences in haplotype frequencies of the combined genetic data are observed between the C. flammea subspecies, and C. cabaret. The slight genetic differentiation within the redpoll complex could result from introgression and/or incomplete lineage sorting following recent and rapid diversification in morphology, possibly driven by environmental factors. |
