Data from: Predominant east to west colonisations across major oceanic barriers: insights into the phylogeographic history of the hydroid superfamily Plumularioidea, suggested by a mitochondrial DNA barcoding marker
We provide preliminary insights into the global phylogeographic and evolutionary patterns across species of the hydrozoan superfamily Plumularioidea (Cnidaria: Hydrozoa). We analysed 1114 16S sequences of 198 putative species of Plumularioidea collected worldwide. We investigated genetic connections and divergence in relation to present-day and ancient biogeographic barriers, climate changes and oceanic circulation. Geographical distributions of most species are generally more constrained than previously assumed. Some species able to raft are dispersed widely. Human-mediated dispersal explains some wide geographical ranges. Trans-Atlantic genetic connections are presently unlikely for most of the tropical-temperate species, but were probably more frequent until the Miocene-Pliocene transition, before restriction of the Tethys Sea and the Central American Seaway. Trans-Atlantic colonisations were predominantly directed westwards through (sub)tropical waters. The Azores were colonized multiple times and through different routes, mainly from the east Atlantic, at least since the Pliocene. Extant geminate clades separated by the Isthmus of Panama have predominantly Atlantic origin. Various ancient colonisations mainly directed from the Indian Ocean to the Atlantic, occurred through the Tethys Sea and around South Africa in periods of lower intensity of the Benguela upwelling. Thermal tolerance, population sizes, dispersal strategies, oceanic currents, substrate preference and land barriers are important factors for dispersal and speciation of marine hydroids.

Fig. 4 Comparison between interspecific and intraspecific pairwise genetic distances in Dorcadionini based on the DNA barcode. Distances were calculated once with all sequences from a species included (graphs on left side) or after excluding taxa resulted from introgression and mitochondrial capture (graphs on right side). With introgression removed, the grey area of overlap between intraspecific and interspecific distances decreases, the number of uncertain cases dropping from 16 to 4 (one square represents one mean pairwise distance)

Figure 3 Subtree of the Neighbor-joining topology based on Kimura 2-parameter distances of all analyzed specimens of Platyarthrus hoffmannseggii Brandt, 1833 and nearest neighbor. Branches with specimen ID-number from BOLD and sample localities. Numbers next to internal nodes are non-parametric bootstrap values (in %) with values higher than 80. BIN values are based on the barcode analysis from 05-06-2020. The isopod drawing by Christian Schmidt was obtained from Raupach (2005).

Triangles show the relative number of individual's sampled (height) and sequence divergence (width). Red triangles highlight terrestrial species with intraspecific maximum pairwise distances > 2.2%, whereas dark blue triangles indicate freshwater species with such distances.
