Multiple matrix regression with randomization (MMRR) analysis performed on genetic distances.

<p>Scatterplots show patterns of isolation-by-distance (A), isolation-by-ecology (B) and the absence of eco-spatial autocorrelation (C) according to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0087469#pone.0087469-ShaferAB1" target="_blank">[4]</a>. When correlations are significant (Mantel test, P<0.05), regression lines are drawn. Plot (D) is based on the results of the multiple matrix regression analysis for the effects of both geographical and environmental distances on genetic distances.
