This paper, based on the MSc
thesis work of the senior author, was given the Editor's
Choice Award by the editors of "Genome,"
Canada's most prestigious genetics and genomics journal.
The award recognizes the quality, clarity, and timeliness

"Like the rest of Atlantic Canada, the island of Newfoundland, during the last Ice Age, was covered by a thick layer of ice and was uninhabitable until the retreat of the glaciers around 10 000 years ago. A long-standing debate is whether returning species survived this Ice Age in mainland refugia, or on southerly island refugia such as the Grand Banks. Genetic analysis of the ecologically diverse Newfoundland caribou shows that they are a distinct subspecies, most closely related to animals from the northern mainland. Genetic exchange of island caribou with Labrador populations may still occur across the Strait of Belle Isle."
