Columns 1 to 6 indicate the statistical differences in genetic variation and population structure between populations of the Northeastern ridge and populations of the Southwestern ridge. Columns 7 and 8 indicate the results of the test of phylogeographic patterns corresponding to the statistical differences between <i>R<sub>ST</sub></i> and <i>pR<sub>ST</sub></i> within the Northeastern ridge and within the Southwestern ridge. * P<0.05; ** P<0.01; *** P<0.001. <sup>NS</sup>Non-Significant test.</p
