<p>Divergence time estimates are given in kyr at the left (in black). Plain gray double arrows indicate 95% Confidence Interval. Values in light gray r indicate lower and upper limits of 95% highest posterior density on divergence times. Directions of migration are represented by dotted grey arrows; numerical values represent the effective number of migrants. Only migrations significantly different from zero are represented (p<0.05). Populations 9.1 to 9.6 refer to genetic groups in <i>X. axonopodis</i> and A1 to A5 refer to ancestral populations.</p
