Pairwise F_ST values were regressed on the logarithm of three-dimensional (3D) distances between plots. For each region/group we give the number of plots N, the slope of the regression (b_log3D), its p-values and the 95% distribution envelope under the null hypothesis that there is no SGS (DE_95%− and DE_95%+).
