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...

BIGORNO. Biodiversité Intertidale sud Gascogne Observation et Recherche de Nouveaux Outils de surveillance et d'aide à la décision - Rapport fiinal ArchiMer
De Casamajor, Marie-noelle; Lalanne, Yann; Huguenin, Laura; Marticorena, Julien; Lissardy, Muriel; Bru, Noelle; D'Amico, Franck; Liquet, Benoît.
This report presents the results obtained during the BIGORNO project whose main objective is to overcome knowledge gaps on the biocenoses of the southern sub-region "Bay of Biscay" to propose a sampling protocol adapted to biogeographic and environmental specific conditions. A stratified random sampling design considering spatial heterogeneity has been implemented. Biodiversity was considered on 0.1 m²quadrats. These data have revealed the organization of benthic communities and the relevant taxa to be considered (species or assemblages of indicator species) in the context of establishing perennial monitoring of intertidal habitats. Proposals are made to implement the descriptors and indicators defined in the Marine Strategy Framework Directive (MSFD).

BIGORNO Project. Intertidal biodiversity in the south of Bay of Biscay new research tools in a context of implementation of the Marine Strategy Framework Directive (MSFD) ArchiMer
De Casamajor, Marie-noelle; Huguenin, Laura; Marticorena, Julien; Lalanne, Yann; Bru, Noelle; Liquet, Benoît; Lissardy, Muriel; D'Amico, Franck; Castege, Iker; Milon, Emilie.
Biodiversity conservation and response of benthic communities to pressures, related to global change and human activities, are a research priority. They also constitute a useful indicator to define the environmental status of the Marine Strategy Framework Directive as part of the European Water Framework Directive (WFD). The biogeographic features of the Aquitanian coast (in terms of rocky substrate communities) induce the interest to have a monitoring and research site. Indeed, it includes the habitat characteristics as well as fauna and flora (the Habitats Directive). The aim of the BIGORNO project is to implement new tools to assess the rocky biocenosis in the southern marine subregion of the Bay of Biscay by integrating fauna communities assessment...

Biodiversity and trophic ecology of hydrothermal vent fauna associated with tubeworm assemblages on the Juan de Fuca Ridge ArchiMer
Lelievre, Yann; Sarrazin, Jozee; Marticorena, Julien; Schaal, Gauthier; Day, Thomas; Legendre, Pierre; Hourdez, Stephane; Matabos, Marjolaine.
Hydrothermal vent sites along the Juan de Fuca Ridge in the north-east Pacific host dense populations of Ridgeia piscesae tubeworms that promote habitat heterogeneity and local diversity. A detailed description of the biodiversity and community structure is needed to help understand the ecological processes that underlie the distribution and dynamics of deep-sea vent communities. Here, we assessed the composition, abundance, diversity and trophic structure of six tubeworm samples, corresponding to different successional stages, collected on the Grotto hydrothermal edifice (Main Endeavour Field, Juan de Fuca Ridge) at 2196 m depth. Including R. piscesae, a total of 36 macrofaunal taxa were identified to the species level. Although polychaetes made up the...

Does spatial distribution of fauna depend on algal belts on intertidal boulder fields of the French Basque coast ? ArchiMer
Marticorena, Julien; Huguenin, Laura; Lalanne, Yann; Bru, Noelle; Liquet, Benoît; De Casamajor, Marie-noelle.
To determine good ecological status and conservation of the Sub-Marine area of the Bay of Biscay, the implementation of a new rocky intertidal habitats monitoring is needed. A protocol has been adapted from the Brittany protocol for the water body FRFC11 "Basque coast" for the two indicators "intertidal macroalgae" and "subtidal macroalgae" under the Water Framework Directive to qualify the ecological. However no protocol has been validated for fauna in front of meridional characters of the benthic communities. Investigations carried out on macroalgae communities on intertidal area in WFD framework, since 2008, constitute an important working basis. This is the aim of the Bigorno project (Intertidal Biodiversity of the south of the Bay of Biscay and...

Exploring Environmental DNA (eDNA) to Assess Biodiversity of Hard Substratum Faunal Communities on the Lucky Strike Vent Field (Mid-Atlantic Ridge) and Investigate Recolonization Dynamics After an Induced Disturbance ArchiMer
Cowart, Dominique; Matabos, Marjolaine; Brandt, Miriam; Marticorena, Julien; Sarrazin, Jozee.
Deep ocean hydrothermal vent ecosystems face physical disturbances from naturally occurring volcanic and tectonic activities and are at increasing risk of mineral resource exploitation, raising concerns about the resilience of endemic biological communities. Following destructive events, efficient and rapidly applicable surveys of organisms are required to monitor the state, evolution and a possible return of these ecosystems to their original baseline status. In this study, we explored the environmental DNA (eDNA) approach as a tool (1) to assess biodiversity of benthic communities associated with deep-sea hard substrata and (2) tracked the recolonization dynamics of benthic invertebrate communities living on the Montségur edifice within the Lucky Strike...
