A new genus of soft coral (Cnidaria, Octocorallia) from the Republic of Congo (Pointe-Noire Region) ArchiMer
Van Ofwegen, Leen P.; Aurelle, Didier; Sartoretto, Stephane.
A new genus of soft coral from the Republic of Congo is described, Complexum gen. n. Nine West African octocoral species previously described in the genus Alcyonium by Tixier-Durivault (1955) are referred to this new genus, and a new species is described and figured, C. pusillum sp. n. The new species is characterized by having encrusting growth form and abundant spiny clubs in the surface of the polyparium. It colonizes shallow calcareous rocky banks (5 to 20 m depth) existing in coastal water of the region of Pointe-Noire. Based on molecular phylogeny this new genus is well separated from Alcyonium species.

Assessment of the ecological status of Mediterranean French coastal waters as required by the Water Framework Directive using the Posidonia oceanica Rapid Easy Index: PREI ArchiMer
Gobert, Sylvie; Sartoretto, Stephane; Rico-raimondino, Valerie; Andral, Bruno; Chery, Aurelia; Lejeune, Pierre; Boissery, Pierre.
This paper describes the PREI (Posidonia oceanica Rapid Easy Index), a method used to assess the ecological status of seawater along Mediterranean French coasts. The PREI was drawn up according to the requirements of the Water Framework Directive (WFD 2000/60/EC) and was tested on 24 and 18 stations in PACA (Provence-Alpes-Cotes d'Azur) and Corsica, respectively. The PREI is based on five metrics: shoot density, shoot leaf surface area, E/L ratio (epiphytic biomass/leaf biomass), depth of lower limit, and type of this lower limit. The 42 studied stations were classified in the first four levels of status: high, good, moderate and poor. The PREI values ranged between 0.280 and 0.847; this classification is in accordance with our field knowledge and with our...

Bathymetric distribution and growth rates of Eunicella verrucosa (Cnidaria: Gorgoniidae) populations along the Marseilles coast (France) ArchiMer
Sartoretto, Stephane; Francour, Patrice.
Gorgonians are important organisms in the Mediterranean Sea, where they form rocky benthic communities. Four main species (3 Holaxonia and 1 Scleraxonia) are predominant in infra- and circalittoral communities of the northwestern Mediterranean basin. Other species, such as Eunicella verrucosa (Pallas, 1766), are more rarely encountered. The expansion to unusually shallow bathymetric levels has been noted in the region of Marseilles (France) (between 20 and 40 m depth). A ten-year monitoring of colonies was used to assess the growth rate according to age (size): from 3.33 cm year(-1) (height <15 cm) to 0.62 cm year(-1) (height >40 cm).

Coralligenous reefs state along anthropized coasts: Application and validation of the COARSE index, based on a rapid visual assessment (RVA) approach ArchiMer
Gatti, Giulia; Bianchi, C. N.; Morri, C.; Montefalcone, M.; Sartoretto, Stephane.
A rapid visual assessment (RVA) approach for the characterization and assessment of the integrity of coralligenous reefs was applied in 21 stations subjected to different levels of anthropogenic pressure, along the French Mediterranean coasts. The reefs were characterized from both the geomorphologic and bionomic (biotic cover, conspicuous species richness, canopy-forming species, etc.) points of view, and their health status was estimated through the COARSE (COralligenous Assessment by ReefScape Estimate) index. The sensitivity of the COARSE index and the robustness of the RVA approach to observer biases were analyzed. Results showed that most coralligenous reefs were characterized by (sub) vertical cliffs or platforms with variable slope, usually...

Etude de l'état de conservation du coralligène basée sur des indicateurs biologiques au sein de la Réserve Naturelle Marine de Cerbère-Banyuls. Campagne 2018 ArchiMer
Sartoretto, Stephane.
Les fonds coralligène constituent un habitat marin remarquable largement distribué dans la Réserve Naturelle de Cerbère-Banyuls. En 2015, un premier travail d'évaluation de l'état de conservation du coralligène a été réalisé par la méthode INDEX-COR. Les résultats ont montré notamment, la nécessité d'adapter les valeurs de références au contexte environnementale de la région de Banyuls, en prenant en compte notamment une plus grande diversité de stations et de faciès. Fort de ce constat, une nouvelle campagne d'acquisition a été réalisée en novembre 2018. Cette campagne avait un double objectif : (i) l'évaluation par l'indice INDEX-COR de l'état de conservation des formations coralligène dans la RNMCB et le suivi de son évolution sur le long terme et (ii)...

Le Ministère de l’Ecologie, de l’Energie et de la Mer a confié au Service du Patrimoine Naturel (Muséum National d’Histoire Naturelle), en lien étroit avec les acteurs de la recherche scientifique, la coordination d’un projet sur l’évaluation de la sensibilité des habitats benthiques aux pressions d’origine anthropique. L’objectif de ce travail est de qualifier la sensibilité générique des habitats présents en France métropolitaine pour aider à l’orientation et à la priorisation de mesures de gestion (pour des activités actuelles ou futures), adaptées aux enjeux de conservation, afin de respecter les objectifs d’atteinte ou de maintien d’un ECF (DCSMM) ou BEE (DHFF). Ce travail permet également de mettre en évidence les habitats et/ou les pressions pour...

Food web structure of a Mediterranean coralligeneous ecosystem ArchiMer
Belloni, Bruno; Sartoretto, Stephane; Cresson, Pierre; Bouchoucha, Marc; Guillou, Gael; Lebreton, Benoit; Ruitton, Sandrine; Harmelin-vivien, Mireille.
The coralligenous ecosystem is one of the biodiversity hotspots in the Mediterranean Sea. This study aims at determining (i) the organic matter (OM) sources at the base of the food web in a coralligenous  ecosystem  near  Marseille  (Cap  Caveau,  Frioul  Island)  and  (ii)  the  global functional structure of its community. For that purpose, C and N stable isotope analyses were performed on 78 compartments or species collected in this habitat between 30 and 40 m depth. Results  suggested  that  the  pelagic  particulate  organic  matter  (POM),  mainly  composed  of phytoplankton, was the main OM source fuelling coralligenous food webs, followed by sedimented organic matter (SOM) and some macrophytes. At least three level of consumers were identified from...

New data concerning the coralligenous atolls of cap corse: an attempt to shed light on their origin ArchiMer
Pergent-martini, Christine; Alami, S; Bonacorsi, Marina; Clabaut, Philippe; Daniel, Boris; Ruitton, Sandrine; Sartoretto, Stephane; Pergent, Gerard.
A new coralligenous morphotype named ‘atolls’ was discovered in 2011 in northern Cap Corse (Western Mediterranean Sea). With the aim of inventorying and characterizing these structures, and to attempt to shed light on their origins, two oceanographic campaigns (using e.g. side scan sonar, multibeam echosounder, sparker, ROV and submarine with 3D photogrammetry) were carried out in 2013 and 2014, in this sector, and in the south of the island in search of similar structures. Off Cap Corse, nearly one thousand atolls were identified between 105 and 130 m depth; the majority of them are situated between 110 and 125 m depth. These atolls are generally grouped (several tens to several hundred) and are to be found in two main sectors, situated between 22 and 31...

Suite à l’acquisition de nouvelles informations sur les habitats marins méditerranéens, une mise à jour du référentiel national était nécessaire pour qu’il soit le reflet des connaissances actuelles. Ces nouvelles informations proviennent principalement de deux campagnes d’exploration des roches profondes et des canyons méditerranéens appelées MEDSEACAN et CORSEACAN, de CARTHAM (Cartographie des Habitats Marins) – deux programmes pilotés par l’Agence des Aires Marines Protégées – ainsi que de propositions émanant directement de la communauté scientifique. En collaboration avec les experts scientifiques benthologues, ces nouvelles observations ont été confrontées à la typologie (Michez et al., 2011) et des modifications et compléments ont été décidés. Ce...
