Fig. 5 in Alcyonidium kuklinskii sp. nov., a new species of Antarctic ctenostome bryozoan with a key to all Antarctic species of the genus
Fig. 5 Maximum likelihood phylogenetic tree of Alcyonidium based on 646 unambiguously aligned nucleotide sites of the COI gene. Values on nodes represent posterior probabilities for BI (based on last 75% of trees) and bootstrap support (1000 replicates), respectively. Support values <50% are not shown. The scale bar represents one substitutional change per 100 nucleotide positions. * Sequence was generated during this study
