title: Genetic diversity and phylogeography of the circumboreal peatland violets (<i>Viola epipsila</i>‐<i>V. palustris</i> complex, Violaceae) as inferred from non‐coding nuclear and chloroplast <scp>DNA</scp> regions
abstract: Abstract The Pleistocene glaciation cycles are a major factor shaping plant genetic diversity, speciation and radiations, and current distribution ranges in the Northern Hemisphere. Case studies are important for improving our understanding of postglacial migration patterns in the Northern Hemisphere taxa in general. Here, we studied the circumboreal Viola epipsila ‐ V. palustris complex, whose taxonomy and patterns of variation are unclear, and phylogeography unknown, using non‐coding nuclear (
