Taxonomy and biogeography of Agarum and Thalassiophyllum (Laminariales, Phaeophyceae) based on sequences of nuclear, mitochondrial, and plastid markers
Abstract Agarum is a perennial kelp genus that has a broad distribution from the northwest Pacific to the northwest Atlantic Ocean. In order to address questions regarding phylogenetic relationships and present‐day distribution patterns of species within this genus, we analyzed the nuclear ITS2, mit...

All analyses of the individual markers and the ITS2 + cox1 + cox3 dataset consistently produced a clade of Agarum that included Thalassiophyllum .

On the basis of these results, we treat Thalassiophyllum as a syn onym of Agarum , reinstating the combination A. clathrus made by Greville in 1830. Despite its wide distribution from Japan through Alaska to the east coast of North America, A. clathratum had low genetic diversity, suggesting a relatively recent long‐distance dispersal of the species. The low degree of substitutions between A. clathratum and A. yakishiriense suggests their recent divergence from a common ancestor, and we recognize the latter as a subspecies of the former.
