Median-joining network of mtDNA haplotypes among herring gull taxa. Median-joining network of 368 concatenated cytB and HVR1 mtDNA sequence haplotypes (see Additional file 2) of all gull taxa included in this study. Distinct haplotype groups are labelled A-I. The network was rooted by the inclusion of previously published [8]occidentalis sequences. The network shows three biphyletic taxa of which individuals either carry clade 1 or clade 2 haplotypes: The European herring gull (argentatus/argenteus - pale blue) in haplogroup B, F and G; the glaucous gull (hyperboreus - grey) in group B, H and I; and the black-backed gull (marinus - black) in haplogroup C, I and H.
