Akanthepsilonema oceanopolis sp. nov. (Nematoda: Epsilonematidae), a new free-living marine nematode from the Condor Seamount (North-East Atlantic Ocean) ArchiMer
Zeppilli, Daniela; Bongiorni, Lucia; Decraemer, Wilfrida; Vanreusel, Ann.
Epsilonematids are epifaunal nematodes characterized by an epsilon-shaped body and the presence of ambulatory setae, which are used in their locomotion. Nematodes belonging to this family were recently found in deep sea, especially in cold-water coral and seamount ecosystems. Akanthepsilonema oceanopolis sp. nov. (Nematoda: Epsilonematidae) is described from sediments of the Condor Seamount (North-East Atlantic Ocean) at 206 m water depth. Its main features are a heterogeneous cuticule with large horn-like dorsal spines both in anterior and in posterior regions; the presence of eight subcephalic setae arranged in two rows and the ratio maximum/minimum body diameter larger than two. The taxonomic position of this new species within the genus is discussed...

Compte Rendu Atelier Phyto Grand Ouest 2017 ArchiMer
Manach, Soazig; Neaud-masson, Nadine.
L’édition 2017 de l’Atelier Phyto du Grand Ouest s’est déroulé les 19 et 20 janvier au LER/MPL de la Trinité sur Mer. Pour cette quatrième édition, 14 analystes du phytoplancton marin de différents LERs (Normandie, Bretagne Nord, Bretagne Occidentale et Morbihan Pays de Loire) se sont réunis afin d’échanger sur les différents problèmes rencontrés, cette année, au cours des identifications et dénombrements du phytoplancton. La coordination REPHY et un agent de DYNECO-PELAGOS se sont joints aux réflexions. Les discussions ont porté principalement sur l’indentification des espèces et l’harmonisation des pratiques de saisies dans la base de données Quadrige².

Compte-rendu atelier phyto du grand ouest 2018 ArchiMer
Legendre, Aurelie; Neaud-masson, Nadine.
Phytoplankton analysts from the North and West coastal regions of France met together for the 5th edition of the phytoplankton workshop between 12 - 13 April 2018 in Dinard. During these two days, the analysts could share the challenges they face regarding the identification of some species and about the development of nomenclature as well.

Le référentiel taxinomique du Système d'information halieutique (SIH) de l 'Ifremer ArchiMer
Woehrling, D..
The adoption of a single reference data base for IFREMER cannot be missed within the framework of continuous monitoring of biological data. This entails standardization of taxa names connected with an up-to-date taxonomic nomenclature, consistent with international valid lists. The necessity of relative stability of IFREMER's taxonomic data base simultaneously opened on nomenclature's evolution imposes the major constraints for structural choices. The SIH taxonomic reference database is the first step toward the future complete reference data base for IFREMER.

Taxinomie et épidémiologie moléculaires du parasite Marteilia refringens Grizel et al. 1974 : intérêt pour la gestion du risque sanitaire en conchyliculture ArchiMer
Berthe, Franck.
Infectious diseases are currently recognised as a major limiting factor to development and sustainability of aquaculture of molluscs. The study is focused on the European flat oyster, Ostrea edulis and its paramyxean parasite Marteilia refringens. Results are contributing to the prevention of risk associated to infected stocks imports from endemic zones, by developing molecular diagnostic tools that are specific, sensible and reliable. Phylogeny and taxonomy of Marteilia refringens, previously impeded by microscopy limits, were clarified by sequencing the rDNA SSU, small sub-unit in the rRNA gene cluster. These new insights have practical implications discussed in a pragmatic polyphasic approach involving pathology and epidemiology. This approach led us to...
