Morvan et al. Timetree of Aselloidea reveals species diversification dynamics in groundwater Appendix 6 Appendix 6 Plots of absolute diversification age estimates (Ma) for different Bayesian relaxed molecular clock models. Left and right panels correspond to data sets inferred by the GMYC method and thresh- old method, respectively. Age estimates along the X-axis are from the uncorrelated lognormal model (BEAST), whereas dating estimates along the Y-axis in the upper and lower panels are from the uncor- related exponential model (BEAST) and the correlated lognormal model (Multidivtime), respectively. Solid lines show linear regressions between age estimations for the different models, and dotted lines in- dicate 1:1 equivalence relationships. Error bars represent 95% posterior density (HPD) intervals for each node. Dating estimates were plotted for 20 benchmark clades spanning Aselloidea diversity: Aselloidea crown group diversification, Asellidae crown group diversification, Stenasellidae crown group diversifica- tion, Bragasellus/Synasellus/Lirceolus/Gallasellus/Caecidotea/Remasellus crown group diversification, Proasellus crown group diversification, divergence between Mexistenasellus coahuila and Stenasellus gal- hanoe, divergence between Proasellus coxalis lineage and Proasellus Alpine/Ibero-aquitanian lineages, divergence between Proasellus Alpine lineage and Proasellus Ibero-aquitanian lineage, divergence be- tween Stenasellus virei/Stenasellus buili clade and other Stenasellus species, Proasellus coxalis lineage crown group diversification, Lirceolus/Gallasellus/Caecidotea/Remasellus crown group diversification, Proasellus Alpine lineage crown group diversification, Spanish Bragasellus crown group diversification, Proasellus Ibero-aquitanian lineage crown group diversification, Proasellus slavus lineage crown group diversification, Asellus crown group diversification, divergence between Proasellus coiffaiti and Proasel- lus slovenicus, Synasellus crown group diversification, and divergence between Proasellus beroni and Proasellus ligusticus. 1.
