Two-tailed Wilcoxon signed-rank sum tests for comparisons of ML branch lengths. Statistical significance at p_family = 0.05 for multiple comparisons using a Bonferroni correction is shown with an asterisk. Using false discovery rates (Benjamini & Hochberg 1995), all results are significant (α < 0.05) except for that from the Southern Hemisphere.
