Multigene phylogeny of the southern bull-kelp genus Durvillaea (Phaeophyceae: Fucales)
Durvillaea (southern bull-kelp) is an economically and ecologically important brown algal genus that dominates many exposed, rocky coasts in the cold-temperate Southern Hemisphere. Of its five currently-recognized species, four are non-buoyant and restricted to the south-western Pacific, whereas one...

Durvillaea (southern bull-kelp) is an economically and ecologically important brown algal genus that dominates many exposed, rocky coasts in the cold-temperate Southern Hemisphere. Of its five currently-recognized species, four are non-buoyant and restricted to the south-western Pacific, whereas one is both buoyant and widely distributed. Durvillaea has had an unsettled taxonomic history. Although its position within the brown algae (Phaeophyceae) has now been largely resolved through the use of molecular techniques, the taxonomic status of several Durvillaea species/morphotypes remains unresolved. Previous molecular phylogenetic studies of phaeophycean taxa have included few Durvillaea samples, and have consequently paid little or no attention to variation within this genus. The current study presents phylogenetic analyses of four genetic markers (mitchondrial: COI; chloroplast: rbcL; and nuclear: 18S and 28S) to resolve phylogenetic relationships within Durvillaea. Results support the monophyly of solid-bladed taxa D. willana, D. potatorum, and D. sp.
