| Asthenognathus atlanticus Monod, 1932, has been reported for the first time from the eastern part of the Bay of Seine (eastern English Channel). A total of 30 specimens were collected between the years 2008 and 2011, along the Normandy coast from Ouistreham to Antifer, mainly on mud and muddy sand habitats, between 10 and 25 m depth. The distribution range of A. atlanticus has been previously known to cover eastern Atlantic coasts from Angola to the western English Channel, where it reached its northern limits. It is also present in the western part of the Mediterranean Sea. The changes in the sediment composition of the eastern Bay of Seine have probably led to the development of a potentially favorable habitat for this species. However, the data... |

| Based on a parallel sampling conducted during autumn 2008, a comparative study of the intertidal benthic macrofauna among 10 estuarine systems located along the Channel and Atlantic coasts of France was performed in order to assess the level of fauna similarity among these sites and to identify possible environmental factors involved in the observed pattern at both large (among sites) and smaller (benthic assemblages) scales. More precisely this study focused on unraveling the observed pattern of intertidal benthic fauna composition and diversity observed at among-sites scale by exploring both biotic and abiotic factors acting at the among- and within-site scales. Results showed limited level of similarity at the among-site level in terms of intertidal... |

| Ce travail constitue le 41ème rapport de surveillance du site électronucléaire de Gravelines dont la grande puissance énergétique est assurée par le fonctionnement de 6 tranches. Ce site, implanté sur le littoral, présente une prise d’eau de mer assurant le refroidissement du système et un rejet côtier d’eau chaude en surface. Le fonctionnement de la centrale a débuté en 1980 et elle a atteint la puissance maximale en 1986. La surveillance concerne les domaines pélagique (hydrologie, microbiologie, phytoplancton, zooplancton), halieutique (larves et œufs de sole, de sprat et crevettes grises), et benthique (intertidal et subtidal). La stratégie de surveillance est basée sur une approche spatiale et temporelle (i) Étude de l’impact immédiat par comparaison... |
