Mitochondrial COI haplogroups and sequences of EF1a of Pyura chilensis. A) Bayesian unrooted phylogram of COI sequences of P. chilensis; node support corresponds to bootstrap values greater than 50 from the maximum likelihood analysis, and to Bayesian posterior probabilities greater than 0.7; B) Bayesian phylogenetic tree of COI haplogroups rooted with three outgroup taxa of the genus Pyura; node support as in A. C) Geographic distribution of COI haplotypes. Each pie represents 100% of the sampled haplotypes, and the subdivisions represent relative frequencies of each haplogroup per locality; D) Bayesian unrooted phylogram of un-Phased EF1a sequences; support for nodes as in A. A-D) In all figures colors represent COI haplogroups; red for COI HG1, green for COI HG2 and blue for COI HG3.
