Lougheed Extensive sampling of polar bears (Ursus maritimus) in the Northwest Passage (Canadian Arctic Archipelago) reveals population differentiation across multiple spatial and temporal scales Ecology and Evolution 3
We use DNA microsatellites and mitochondrial control region sequences to quantify genetic differentiation, estimate gene flow, and infer population history of polar bears (Ursus maritimus) from across the center of the Canadian Arctic Archipelago. Our findings support the designation of two conservation units and provide a striking example of how nuclear DNA and mtDNA capture different aspects of a species demographic history.
