Data from: Molecular population genetics of the melanic plumage polymorphism in arctic skuas (Stercorarius parasiticus): evidence for divergent selection on plumage colour
The arctic skua (Stercorarius parasiticus) is a classic example of an avian plumage polymorphism, with variation in melanin-based ventral plumage coloration defining pale, intermediate and dark morphs in adults of both sexes. However, despite several decades of field research, there is an incomplete...

Here we investigate selection on a locus (MC1R) that is strongly associated with plumage colour variation in arctic skuas using patterns of nucleotide variation and comparison to neutral loci (nuclear introns and mtDNA). We find that three linked non-synonymous mutations in MC1R, including the single mutation described previously, are associated with plumage colour in the arctic skua. The position of non-synonymous mutations on a MC1R haplotype network implies that divergent selection drove the initial evolution of the colour morphs. Comparisons of FSTs of MC1R vs. nuclear introns among five skua populations differing in proportion of dark morphs along an approximate north-south cline reveals a signature of divergent selection on MC1R. In contrast, we find limited evidence for balancing selection on MC1R within populations, although the power is low. Our results provide strong evidence for both past and ongoing selection on MC1R, and, by implication, plumage colour in arctic skuas. The results suggest that a fruitful avenue for future ecological studies will be analysis of selection on morphs in colonies at the extremes along the morph ratio cline.
