A new species of the Marphysa sanguinea complex from French waters (Bay of Biscay, NE Atlantic) (Annelida, Eunicidae) ArchiMer
Lavesque, Nicolas; Daffe, Guillemine; Bonifacio, Paulo; Hutchings, Pat.
A new species of Eunicidae, Marphysa victori sp. n., has been identified from Arcachon Bay, Bay of Biscay, NE Atlantic. This new species, belonging to the sanguinea complex, is characterised by branchiae with long filaments from chaetigers 26–34, the presence of four types of pectinate chaetae with first ones present from chaetiger 2, a large number of both pectinate chaetae and compound spinigers, and the pygidium with only one pair of pygidial cirri. An identification key for European species of the genus Marphysa is provided.

Assessment of the impact of a wastewater treatment process including Advanced Oxidation Technique on environment using chemical and biological indicators ArchiMer
Caill-milly, Nathalie; De Casamajor, Marie-noelle; Pigot, Thierry; Paulin, Thomas; Bru, Noëlle; Sanchez, Florence; Marticorena, Julien; Lanceleur, Laurent; Gonzalez, Patrice; Daffe, Guillemine.
In a context of several directives for transitional and coastal waters masses (Water Framework Directive, Marine Strategy Framework Directive and Bathing Water Directive), the good ecological status of water but also conservation of marine ecosystem should be quickly achieved. The Basque coastline (SE of the Bay of Biscay) is subject to strong human pressures with a high density of population over the year, and especially during the summer with tourist activities. It generates nutrient discharge, water and sediment pollution and impacts the quality of the marine environment. Such pressure and the way to reduce its impacts are the main concerns of authorities Locally, in order to improve wastewater treatment process, an alternative technical solution is...

Can pesticides, copper and seasonal water temperature explain the seagrass Zostera noltei decline in the Arcachon bay? ArchiMer
Gamain, Perrine; Feurtet-mazel, Agnes; Maury-brachet, Regine; Auby, Isabelle; Pierron, Fabien; Belles, Angel; Budzinski, Helene; Daffe, Guillemine; Gonzalez, Patrice.
Dwarf eelgrasses (Zostera noltei) populations have decreased since 2005 in Arcachon Bay (southwest France). Various stressors have been pointed out, however the role of xenobiotics like pesticides or copper (Cu) and of parameters like water temperature warming have not yet been explored. To determine their impact, Z. noltei individuals were collected in a pollution-free site and transferred to the laboratory in seawater microcosms. This dwarf eelgrass was exposed to a pesticide cocktail and copper, alone or simultaneously, at temperatures (10 °C, 20 °C, 28 °C) representative of different seasons. After a two-week contamination, leaf growth, leaf bioaccumulation of Cu, and differential expression of target genes were studied. Eelgrasses bioaccumulated Cu...
