Abstract: Aim To describe and analyse asteroid biogeographic patterns in the Southern Ocean (SO) and test whether reproductive strategy (brooder versus broadcaster) can explain distribution patterns at the scale of the entire class. We hypothesize that brooding and broadcasting species display different biogeographic patterns.Location Southern Ocean, south of 45°S.Methods Over 14,000 asteroid occurrences are analysed using bootstrapped spanning network (BSN), non-metrical multidimensional scaling (nMDS) and clustering t… Show more

“…Most of the results obtained in the present study are in line with this expected biogeographic pattern, with the prevalence of clear spatial structures in brooders. This is in agreement with our previous work describing the SO asteroid biogeographic patterns and demonstrating the importance of life history traits to understanding the structure of spatial distributions (Moreau et al, ). Our results support the differentiation of species between the Antarctic Peninsula and the East Antarctic.…”

“…Delineated clades are represented, and color code follows the central map: red-South Georgia; pink-South Sandwich Islands; yellow-Bouvet Island; dark blue-Kerguelen Islands; light blue-East Antarctica; light green-Amundsen Sea; orange-Antarctic Peninsula; dark green-Burdwood Bank; and purple-Weddell Sea. Projection: South Pole Stereographic our previous work describing the SO asteroid biogeographic patterns and demonstrating the importance of life history traits to understanding the structure of spatial distributions(Moreau et al, 2017).

“…For example Matschiner et al (2009) concluded that the lack of genetic structuring between populations of the notothenioid, Gobionotothen gibberifrons, throughout the Scotia Sea could be assigned to the passive transport of their larvae during the pelagic development phase by the ACC as indicated by surface drifter trajectories. The geographic distribution of marine taxa within the Southern Ocean reflects the species life-history traits (including bathymetric ranges, developmental modes and larval lifespans) and the influence of circum-Antarctic current systems (Young et al, 2015;González-Wevar et al, 2017;Moreau et al, 2017).…”
