Colonization history of the high‐arctic pink‐footed goose Anser brachyrhynchus
Abstract Population structure and phylogeography of the pink‐footed goose, Anser brachyrhynchus Baillon 1833, was studied using mtDNA control region sequences (221 bp) from 142 individuals. Present breeding areas of the species in Greenland, Iceland, and Svalbard were largely covered by ice during t...
