Figure 3 in Vicariant versus dispersal processes in the settlement of Pseudamnicola (Caenogastropoda, Hydrobiidae) in the Mediterranean Balearic Islands

Figure 3. *BEAST chronograms of Pseudamnicola (Pseudamnicola) populations from the Ibero-Balearic region based on different calibrations: A, combined analysis of cytochrome c oxidase subunit I (rate previously calibrated for hydrobiids) and 16S rRNA and 28S rRNA ribosomal fragments (rates estimated), B, combined analysis in which all the rates and ages were estimated by a geological event (the separation of Minorca Island from the continent). *BEAST posterior probabilities were 0.99, except for the one indicated with a black dot, which was 0.75. Grey bars indicate 95% highest posterior density intervals. Black arrows on branches indicate no constancy in evolutionary rates using the relative rate test.
