Fig2. Bayesian inference phenogram with General Time Reversible model with invariable sites (GTR+I), displaying 76 COI sequences of Laeonereis culveri from 10 different populations/localities. Bracket color correspond to different MOTUs, as represented in figure 1.
Fig3. Reduced median network based on COI data. The number of haplotypes is indicated in each circle. Number of mutations separating each haplotype and inferred ancestors (median vectors) are displayed within the branches.
