Phylogeography of Chilean bull-kelp. A) ML phylogeny of D. antarctica for COI including data from 17 new localities in Chile, as well as published sequences from 7 localities in central Chile (indicated by asterisks), and localities in New Zealand and the subantarctic [19]. Coloured triangles represent haplotypes found in Chile, with colours corresponding to those in panel B and Fig 3. Bayesian PP values are shown in black above the line, and ML bootstraps are in grey below the line. Support values < 50% are not shown, nor are values on some minor, distal branches within the major clades. Outgroups have been trimmed for clarity. B) Location of all sampled localities along the coast of Chile. Pie charts indicate distribution and proportions of haplotypes, with haplotype colours corresponding to those in panel A and Fig 3. Grey numbers to the left of pie charts show total number of samples from each locality.
