The relationship between the mean trunk perimeter and genetic parameters in Taxus baccata populations. AR, the mean allelic richness; He, the mean expected heterozygosity; Admix, the admixture rate inferred based on STRUCTURE (for K = 9); ΔMR, the difference between expected (under demographic stability) and observed value of the Garza-Williamson bottleneck index (MR); Ne, the effective population size (the harmonic mean across 2 estimators); Ne/N, the ratio of effective to census population size; DIY-ABC parameter estimates: N0μ, the current (mutation-scaled) effective size; N0/NA, the ratio of current to ancestral (before demographic event) effective size; τ, the time to demographic event backward in time (in generations × mutation rate). p values show the significance of the Spearman correlation analysis performed with the Czersk population being included and excluded in the analysis
