FIGURE 7 in Two newly recorded invasive alien ascidians (Chordata, Tunicata, Ascidiacea) based on morphological and molecular phylogenetic analysis in Korea*
FIGURE 7. Phylogenetic relationship of some ascidians including three invasive alien species inferred from mt–COI dataset. Species, sampling locations in Korea and Genbank accession numbers were given and numbers on branches were Bayesian posterior probabilities (if ≥ 0.80). The tree was rooted with Branchiostoma floridae. The scale bar represents the number of expected changes per site.

FIGURE 6. Phylogenetic relationship of some ascidians including four invasive alien species inferred from nuclear 18S rDNA dataset. Species, sampling locations in Korea and Genbank accession numbers were given and numbers on branches were Bayesian posterior probabilities (if ≥ 0.80). The tree was rooted with Branchiostoma floridae. The scale bar represents the number of expected changes per site.
