Population structure of A. schaueriana inferred from genome-wide genotyping of single nucleotide polymorphic (SNP) loci. (a) Density of individuals on the first retained discriminant function, calculated using a multivariate method, the discriminant analysis of principal components (DAPC); different colors represent inferred populations; (b) map showing the distribution of the species (green-shaded area), the geographical location of sampling sites (points) and barplots in which each color denotes an ancestral cluster and each bar represents an individual as inferred by the model-based method implemented in Admixture 1.3.0.
