Phylogenetic analyses of the Laurencia complex (Rhodomelaceae, Ceramiales) support recognition of five genera: Chondrophycus, Laurencia, Osmundea, Palisada and Yuzurua stat. nov. ArchiMer
Martin-lescanne, Julie; Rousseau, Florence; De Reviers, Bruno; Payri, Claude; Couloux, Arnaud; Cruaud, Corinne; Le Gall, Line.
Molecular phylogenies inferred from rbcL sequences including 39 representative members of the Laurencia complex confirm the four genera currently recognised within the complex: Laurencia sensu stricto, Osmundea, Chondrophycus and the recently described genus Palisada. Furthermore, Palisada poiteaui was resolved as a fifth independent lineage suggesting that the complex is actually composed of five rather than four genera. Palisada poiteaui is the type species of the subgenus Yuzurua, and elevation of this subgenus to generic rank is proposed. This new genus allied strongly with Laurencia s.s. However, the other intergeneric relationships were not well supported, suggesting that rbcL sequences may not have sufficient signal to clarify infrageneric...

Species Diversity, Phylogeny and Large Scale Biogeographic Patterns of the Genus Padina (Phaeophyceae, Dictyotales) ArchiMer
Silberfeld, Thomas; Bittner, Lucie; Fernandez-garcia, Cindy; Cruaud, Corinne; Rousseau, Florence; De Reviers, Bruno; Leliaert, Frederik; Payri, Claude E.; De Clerck, Olivier.
The brown algal genus Padina (Dictyotales, Phaeophyceae) is distributed worldwide in tropical and temperate seas. Global species diversity and distribution ranges, however, remain largely unknown. Species-level diversity was reassessed using DNA-based, algorithmic species delineation techniques based on cox3 and rbcL sequence data from 221 specimens collected worldwide. This resulted in estimates ranging from 39 to 61 putative species (ESUs), depending on the technique as well as the locus. We discuss the merits, potential pitfalls, and evolutionary and biogeographic significance of algorithmic species delineation. We unveil patterns whereby ESUs are in all but one case restricted to either the Atlantic or Indo-Pacific Ocean. Within ocean basins we find...
