Estimation of demographic parameters for the three ESUs identified within <i>Entomacrodus vomerinus</i>.

<p>The Tropical Southwestern Atlantic map highlights: the sampling localities (circles), population clusters defining ESUs (colored polygons), ocean currents affecting those localities (full arrow—South-Equatorial current which splits in the Brazil Current and the North Brazil Current represented by the dotted arrow; dashed arrow—Equatorial Undercurrent [<a href="" target="_blank">45</a>]). The marginal posterior density curves represent the likelihood surface for the demographic parameters co-estimated in each of the two comparisons. Note that gene flow reflects 2Nm estimates forward in time, from population splitting to the present. The direction of migration when thinking forwards in time is reversed from that reflected by the 2Nm parameter [<a href="" target="_blank">42</a>] (<a href="" target="_blank">Table 3</a>), which is estimated backwards in time in the coalescent direction.</p>
