(A) Observed (HO) and expected (HE) heterozygosity of aspen in the PMM (peat-mineral mix), FFMM (forest floor-mineral mix), Mature and Fire sites. Error bars represent the standard errors. (B) Biplot of the first two axes of a discriminant analysis of principal components (DAPC) on aspen GBS data using the four types of sites (PMM, FFMM, Mature and Fire) as groups. The inset shows the eigenvalues of each discriminant axis (total of 33% of the genetic variance explained).
