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... |

The tanaidacean crustacean, Zeuxo holdichi was first described from Arcachon Bay, France, by Bamber in 1990. Since then, this species has been recorded several times in Europe, from Iberian Peninsula to Germany. In this present study, we report new records of this species along the northern coasts of France bordering the English Channel. It is hypothesized that Z. holdichi is being spread because of aquaculture activities. |

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... |

This is the 37th annual surveillance report concerning the nuclear power plant of Gravelines. Its very high power level results from six plant units located on the shore and is characterised by a cooling system with a coastal surface input and output. The production of electricity began in 1980 and reached maximum in 1986. Surveys concern monitoring of pelagic system (hydrology, microbiology, phytoplankton, and zooplankton), fish populations (larvae and eggs of Sole and Sprat) or crustaceans (shrimps), and benthic macrofauna (intertidal and subtidal). This survey deals with spatial and temporal approaches (i) study of the direct impact by comparison of the input and output seawater stations, (ii) study of medium and long term evolution of the area by... |

Using recent indices developed, in part, for use under the European Water Framework Directive (AMBI, BENTIX, BOPA BQI, I2EC and the trophic index ITI), the ecological quality status of two highly contaminated environments-the Bay of Seine and the Seine estuary (Eastern English Channel)-was determined on several spatial and temporal scales. Data from 604 observations gathered over a 14-year period (1988-2002) were analyzed, and the results used to show the relationship between biotic indices, environmental variables and classic descriptors (e.g., number of species, total abundance, dominance index, ES(50) and Shannon/Brillouin diversities). Though the specific ecological quality (EcoQ) values calculated with the various indices were different, the overall... |
