Genetic variance partitioning (AMOVA), isolation-by-distance (Mantel tests) and neutrality tests (D and F_S).

<p>Levels of significance: >5% (n.s.), 5% (*), 1% (**), and 0.1% (***), but 5% significance level of F_S was indicated when P<0.02 <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0071577#pone.0071577-Fu1" target="_blank">[56]</a>. In one occasion, Mantel test could not be conducted due to insufficient number of populations (!).
