Figure 3 in A molecular phylogenetic appraisal of the systematics of the Aglaopheniidae (Cnidaria: Hydrozoa, Leptothecata) from the north-east Atlantic and west Mediterranean
Figure 3. Maximum likelihood phylogenetic analysis of the dataset containing all the 16S Aglaopheniidae sequences used in this study. Note that the part of the phylogenetic tree with all the branches of the Aglaophenia pluma complex is represented in a separate figure – Figure 5. Numbers near the nodes indicate the values of bootstrap (left) and posterior probabilities (right) in percentages. Values less than 70% are replaced by <; if equal to 100%, an asterisk is used instead. Values of bootstrap and posterior probabilities are omitted if both were less than 70% for the same node. The branch length indicator represents 0.1 substitutions per site.
