  1. Mantel tests for correlation between genetic and geographic distance (measured in kilometers).
  2. aP-values are one sided and based on 1000 permutations. The null hypothesis is that the correlation coefficient is ⩽0.
  3. bGenetic distance measured by pairwise Fst rather than the Tamura–Nei genetic distance.
