marginally significantP = 0.049
At the entire population and regional scales, lack of correlations between genetic ( F ST ) and geographic distances (both linear and altitudinal slope) was a common phenomenon according to the Mantel test, and only the SE-SW comparison showed a marginally significant correlation between genetic distance and linear geographic distance ( r = 0.314, P = 0.049 for Chs sequences and r = 0.295, P = 0.047 for Lfy sequences, 1000 permutations, one-tailed test).
