Diversity, systematics and biogeography of French Polynesian Lobophora (Dictyotales, Phaeophyceae)

Figshare (2022)

Christophe Vieira Olivier De Clerck Antoine De Ramon N’Yeurt Sofie D’hondt Laurent Millet

We re-evaluated the diversity of Lobophora using an integrative taxonomic approach based on a broad sampling across French Polynesian archipelagos. Our results show that French Polynesia supports at least 37 Lobophora species of which ~57% (21) are endemic. This level of endemicity is comparable to that presently known in the Caribbean and the western Indian Ocean, while French Polynesian coastlines cover a much smaller length. With a third of the species in common, French Polynesia shares considerable biogeographic affinities with the Melanesian Islands, situated over 4000 km to the west. Distribution ranges of a few species reach the western Indian Ocean, and two species also occur in the Atlantic. We hypothesize that Lobophora species in French Polynesia have mainly evolved into endemic species from colonizers originating from the Central Indo-Pacific. These rare dispersal events to ocean archipelagos followed by a long period of isolation and speciation represent an important process responsible for the high level of endemism in remote archipelagos. While south-eastern Pacific Islands could be considered an ‘evolutionary graveyard’ for the genus Lobophora as little local radiation occurred, this may simply be due to recent evolutionary history. Based on these new data, the diversity of Lobophora represents ~10% of French Polynesian seaweed diversity. Eighteen new species of Lobophora are here described from French Polynesia. Lobophora species diversity and biogeography in French Polynesia were investigated.Twenty-three species of Lobophora were newly identified, and 18 new species were described.This is the first inter-archipelago diversity and biogeographic study for a macroalgal genus in the French Polynesian region.

Rhipilia penicilloides sp. nov. (Udoteaceae, Chlorophyta) from Fiji

Phycologia (1997)

Antoine De Ramon N’Yeurt D. W. Keats

AbstractRhipilia penicilloides sp. nov. (Udoteaceae, Chlorophyta) is described from the Fiji Islands, South Pacific. Adult thalli are characterized by a penicilloid capitulum of free, dichotomously branched siphons and an elongated corticated stipe arising from a multisiphonous rhizome-like mat or stolon, whereas juvenile stages possess an infundibular capitulum held together by abundant lateral tenaculiferous branch lets. The generic placement of the new species is debatable owing to its close affinities to both the genera Chlorodesmis and Rhipilia, but present evidence favors the latter.

A preliminary annotated checklist of the marine algae and seagrasses of the Wallis Islands (French Overseas Territory of Wallis and Futuna), South Pacific

Australian Systematic Botany (2004)

Antoine De Ramon N’Yeurt Claude Payri

A total of 194 species of marine algae (14 Cyanobacteria, 41 Chlorophyta, 11 Heterokontophyta and 128 Rhodophyta), as well as three species of seagrasses, represent the first published records for the isolated island of Wallis, South Pacific. The flora has its strongest affinities with Fiji and Rotuma, followed by Samoa and French Polynesia. The lack of diverse habitats and its geographical location are invoked to explain the relatively low species richness compared with localities such as Fiji and Samoa. The flora has a typically tropical component dominated by encrusting coralline red algae, the calcified green algal genera Halimeda, and assemblages of Cyanobacteria. Normally ubiquitous species such as Halimeda discoidea, and the brown algal genera Hydroclathrus, Colpomenia, Rosenvingea, Asteronema, and Chnoospora are notably absent from the island, perhaps due to seasonality and the lack of suitable habitats. The minute epiphytic red alga Acrochaetium kurogii is reported for the first time outside of its type locality in Japan, while two as yet unidentified species of red algae (Gracilaria sp. and Sebdenia sp.) could represent new taxa if further useful material is found.

Benthic algal and seagrass communities in Baa atoll, Maldives

Atoll research bulletin (2012)

Claude Payri Antoine De Ramon N’Yeurt Lydiane Mattio

The present survey was undertaken to provide the first census of the marine flora (macroalgae and seagrasses) of Baa atoll, one of the 26 Maldivian atolls, and to serve along with the macro-fauna biodiversity inventories for conservation purposes. Species collection and inventories have been conducted at 27 sites covering the widest selection of habitats recognized based on satellite images including islands shorelines, reef flats, faros, patch reefs, passes as well as shallow and deep outer reef slopes. A total of 405 specimens were collected and 176 species representing 10 Pheaophyceae, 58 Chlorophyta, 108 Rhodophyta and two seagrasses were identified. The lagoon patch reefs and the oceanic reef slopes were the most diverse geomorphological habitat types and displayed the highest species richness with 38 spp. All lagoon sites shown a similar richness compared to each other with an average species number of 26 spp, while the deep lagoon floor and the seagrass beds in oceanic-exposed reef flats were the less species-rich habitats. The most common species, occurring at all visited sites, were Tydemania expeditionis and Halimeda minima and the most species rich genera appeared to be Halimeda and Caulerpa. No community structure nor strongly supported species assemblages associated to geomorphological habitat types was found. Previous lists available for other Maldivian atolls listed 208 algal species. Sixty of these records were found in Baa Atoll while 113 of the species recorded in the present study represent new records for the Maldives bringing the total number of algal species to 321. The resulting species list shows that the Maldivian algal flora is typically tropical and most of the species belong to the Indo-Pacific biogeographic province. In this paper, we give a general description of the representative macrophyte communities of Baa atoll in relation to the geomorphology of reefs.

Marine algae from the Suva lagoon and reef, Fiji

Australian Systematic Botany (2001)

Antoine De Ramon N’Yeurt

A total of 222 taxa (excluding Cyanophyceae and non-geniculate corallinales) are reported from the Suva Lagoon and Reef (Fiji), consisting of 71 Chlorophyceae, 24 Phaeophyceae and 127 Rhodophyceae. Of these, five represent new or undescribed species. The Suva flora is comparatively impoverished with only 222 species, although the relative percentage of the three classes is comparable to the overall Fijian flora, in particular with respect to the Rhodophyceae.
