Phylogeography of a Holarctic rodent ( Myodes rutilus): testing high‐latitude biogeographical hypotheses and the dynamics of range shifts
Abstract Aim We used the Holarctic northern red‐backed vole ( Myodes rutilus ) as a model organism to improve our understanding of how dynamic, northern high‐latitude environments have affected the genetic diversity, demography and distribution of boreal organisms. We tested spatial and temporal hyp...
