The presence of refugia in the Canadian High Arctic has been subject to debate for decades. We investigated the potential existence of Arctic refugia during the Pleistocene for a large mammal species in the Canadian Archipelago because if these refugia were present, reconsideration of the evolutionary histories of North American fauna and flora beyond the major refugia of Beringia and south of...

Glacial‐interglacial cycles influenced the contemporary genetic structure of many North American species. While phylogeographical lineage divergence among Pleistocene refugia has been proposed as a significant driver of subspecific and ecotypic differentiation, emerging evidence highlights the role of diversification within refugia in producing post‐glacial variation. Caribou (Rangifer tarandus...
