Quantifying the similarity between genes and geography across Alaska's alpine small mammals
Abstract Aim Quantitatively evaluate the similarity of genomic variation and geography in five different alpine small mammals in Alaska, and use this quantitative assessment of concordance as a framework for refining hypotheses about the processes structuring population genetic variation in either a...
