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. Details of the
datasets and methods are available in the published manuscript and
supplementary information: https://doi.org/10.1111/mec.70082 The
raw genetic data for the study have been deposited in the European
Nucleotide Archive (ENA) at EMBL-EBI under accession number PRJEB67938.
The data and code deposited in Dryad will help enable replication of the
methods of the paper.
