“…Many genera (Hydroclathrus, Rosenvingea, Pseudochnoospora) belonging to the family Scytosiphonaceae are blooming seasonally after the cool season between September and December [51]. The abundance of some Dictyotaceae species varies strongly between seasons, such as the genus Padina, which has the highest cover during the austral summer [19].…”

“…The latest published works on French Polynesian marine flora reported a total of 332 species of marine macroalgae (198 Rhodophyta, 32 Ochrophyta, 82 Chlorophyta [ 14 , 15 , 16 ]), 117 Cyanobacteria [ 17 ], and 2 seagrasses [ 18 ]. Since then, only a limited number of taxonomic studies have been conducted in French Polynesia, e.g., [ 13 , 19 , 20 , 21 ].…”

Located in the heart of the South Pacific Ocean, the French Polynesian islands represent a remarkable setting for biological colonization and diversification, because of their isolation. Our knowledge of this region’s biodiversity is nevertheless still incomplete for many groups of organisms. In the late 1990s and 2000s, a series of publications provided the first checklists of French Polynesian marine algae, including the Chlorophyta, Rhodophyta, Ochrophyta, and Cyanobacteria, established mostly on traditional morphology-based taxonomy. We initiated a project to systematically DNA barcode the marine flora of French Polynesia. Based on a large collection of ~2452 specimens, made between 2014 and 2023, across the five French Polynesian archipelagos, we re-assessed the marine floral species diversity (Alismatales, Cyanobacteria, Rhodophyta, Ochrophyta, Chlorophyta) using DNA barcoding in concert with morphology-based classification. We provide here a major revision of French Polynesian marine flora, with an updated listing of 702 species including 119 Chlorophyta, 169 Cyanobacteria, 92 Ochrophyta, 320 Rhodophyta, and 2 seagrass species—nearly a two-fold increase from previous estimates. This study significantly improves our knowledge of French Polynesian marine diversity and provides a valuable DNA barcode reference library for identification purposes and future taxonomic and conservation studies. A significant part of the diversity uncovered from French Polynesia corresponds to unidentified lineages, which will require careful future taxonomic investigation.
