Results of phylogenetic and haplotype network analyses for Sclerolinum contortum. a Phylogeny of S. contortum individuals using the COI gene with vertical bars representing haplotype groups, coloured according to population location; HMMV -dark purple, Loki’s Castle (prefix LC) – light purple, GoM – light blue, and the Antarctic (prefix Ant) – dark blue. The siboglinids Riftia pachyptila and Siboglinum ekmani were used as outgroups (not shown), and sequences obtained from NCBI GenBank have the suffix ‘_gb’ (see Additional file 5: Table S4 for accession numbers). b Map of the Atlantic and part of the Southern Ocean showing the locations of the four S. contortum populations used in this study, world map source: Wikipedia. (https://en.wikipedia.org/wiki/Contemporary_history#/media/File:WorldMap.svg). c Haplotype network constructed using the gene COI, sequenced from animals from four different S. contortum populations. Gaps were treated as missing data, and the connection limit was set to 95 %. Each line represents one change, and black dots represent missing haplotypes. Haplotype network was drawn using PopART (http://popart.otago.ac.nz)
