Data for: Molecular footprints of Quaternary climate fluctuations in the circumpolar tundra shrub dwarf birch

Data and code to accompany the manuscript "Molecular footprints of Quaternary climate fluctuations in the circumpolar tundra shrub dwarf birch".

We tested scenarios of the Quaternary demographic history of dwarf birch species (Betula nana L. and Betula Glandulosa Michx.) using Single Nucleotide Polymorphism (SNP) markers obtained from RAD sequencing and approximate Bayesian computation. We compared the timings of modelled population events with ice sheet reconstructions and other paleoenvironmental information to untangle the impacts of alternating cold and warm periods on the phylogeography of dwarf birch.
