Patterns of genetic differentiation: a Matrix of pairwise FST values between the 22 cembra pine (Pinus cembra L.) populations. Colors representing Nei’s genetic distances are defined on the scale at the right side of the figure. b Two-dimensional plot of the two main principal components (PC) and their part of the total variance in % using Principle Component Analysis (PCA). Population abbreviations are as explained in Table 1
