Given are the number of loci, the number of populations sampled in the two mountain ranges, the F-statistics from an AMOVA, and the difference in the Structure assignments between the Alps and the Carpathians (β_AC). The β_AC values are given for the analysis of the full data set, the analysis with the alternative ancestry model (with two initial values of the alpha parameter), and for the analysis where the data set was subsampled to balance the number of population samples in the two mountain ranges (average shown over 500 replicate subsamples)
