Phylogenetic relationship of five component orders belonging to the subclass Copepoda based on Bayesian analysis. Two Branchiopoda and two Maxillopoda species were used as out-groups. Trees from various analyses are of the same topology. Only the tree inferred from original dataset using the model of CAT + mtArt is shown. Each group of four numbers at the branch nodes (clockwise) represents the Bayesian posterior probabilities of four analyses, Ori_ART, Ori_CAT, Bal_ART and Bal_CAT. The names were abbreviated as depicted in Figure 8.
