plant DNA analysis of white spruce, Alaska and adjacent Canada
The motivation of the study: We conducted a population genomics analysis of white spruce (Picea glauca) in Eastern Beringia (Alaska and adjacent Canada) in order to infer the location of putative glacial refugia during the last glacial maximum and assess postglacial spread of genetic lineages.
