Population structure analyses
Based on the final combined dataset of 642 individuals (GT-seq+ddRADseq
data at 324 GT-seq loci), all subpopulations display similar levels of
genetic diversity (Table 2). Expected heterozygosity values ranged from
0.42 to 0.45 and GIS values were mostly negative,
ranging from -0.006 to 0.004.

subpopulations (see Figure S1) based on a combined GT-seq+ddRADseq
dataset consisting of 642 individuals genotyped at 322 autosomal loci.
