“…A similar west to east pattern of dispersal has also been found for: the sea stars of the genus Leptasterias (Foltz et al. ), the cod genus Gadus (Stroganov ), a number of polychaetes and echinoderms (Hardy et al. ), as well as whelks from the genus Nucella (Marko et al.…”

The genus Laminaria has a wide distribution range compared with other kelp genera because it is found in both the North and the South Atlantic, on both sides of the North Pacific, as well as in the Mediterranean. Hypotheses behind this biogeographical pattern have been discussed by several authors but have not yet been fully evaluated with time-calibrated phylogenies. Based on the analysis of four molecular markers (ITS2, rbcL, atp8 and trnWI), our goal was to reassess the Laminaria species diversity in South Africa, assess its relationship with the other species distributed in the South Atlantic and reconstruct the historical biogeography of the genus. Our results confirm the occurrence of a single species, L. pallida, in southern Africa, and its sister relationship with the North Atlantic L. ochroleuca. Both species belonged to a clade containing the other South Atlantic species: L. abyssalis from Brazil, and the Mediterranean L. rodriguezii. Our time-calibrated phylogenies suggest that Laminaria originated in the northern Pacific around 25 mya, followed by at least two migration events through the Bering Strait after its opening (~5.32 mya). Today, the first is represented by L. solidungula in the Arctic, while the second gave rise to the rest of the Atlantic species. The colonization of the North Atlantic was followed by a gradual colonization southward along the west coast of Europe, into the Mediterranean (~2.07 mya) and two recent, but disconnected, migrations (~1.34 and 0.87 mya) across the equator, giving rise to L. abyssalis in Brazil and L. pallida in southern Africa, respectively.

“…Similarly, differences in breeding tubercles on the scales are attributable to population-level differences. Most recently, a further assessment of the situation using additional morphometric, biochemical, and molecular methods (Stroganov, 2015) supports the synonymy of G. macrocephalus and G. ogac. We also note that Cohen et al (1990) and Mecklenburg et al (2011) did not synonymize the Atlantic cod G. morhua and G. macrocephalus, as claimed by Stroganov (2015).…”

“…The RUSALCA 2009 specimens were identified as a different species and as many as five species of Arctogadus were indicated to be present nearby in the presence of ogac (G. macrocephalus) in the White Sea is uncertain and requires further study (it could coexist there with G. morhua), we give the established to the White Sea. In Stroganov (2015), all cods in the White Sea are grouped as "White Sea cod" without providing scientific species names. Since the FIGURE 8.…”
