Fig. 10 in Taxonomy, genetic diversity, and phylogeny of the Antarctic mud dragon, Polacanthoderes (Kinorhyncha: Echinorhagata: Echinoderidae)
Fig. 10. Maximum-likelihood tree of Kinorhyncha based on 18S (1353 bp) + 28S (2750 bp) dataset. Numbers near nodes are the maximum-likelihood bootstrap (BS) and Bayesian posterior probability (PP) values, respectively; asterisks indicate the node with the full support values (BS = 100% and PP = 1.00); BS values lower than 50% indicate as polytomy; PP values lower than 0.95 are indicated by dashes. The scale bar indicates branch length in substitutions per site.
