SNP data were generated using a genotype-by-sequencing genome reduction method (see Elshire et al, 2011 doi.org/10.1371/journal.pone.0019379 and Kingston et al. 2018 DOI: 10.1111/jeb.13224) and using the de novo alignment and SNP calling program STACKS (Catchen et al. 2011 and 2013 doi.org/10.1534/g3.111.000240 and DOI: 10.1111/mec.12354)

Missing data in structure format is represented by -9
