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... |

Blastodinium is a genus of dinoflagellates that live as parasites in the gut of marine, planktonic copepods in theWorld’s oceans and coastal waters. The taxonomy, phylogeny, and physiology of the genus have only been explored to a limited degree and, based on recent investigations, we hypothesize that the morphological and genetic diversity within this genus may be considerably larger than presently recognized. To address these issues, we obtained 18S rDNA and ITS gene sequences for Blastodinium specimens of different geographical origins, including representatives of the type species. This genetic information was in some cases complemented with new morphological, ultrastructural, physiological, and ecological data. Because most current knowledge about... |

This is the 24th annual surveillance report concerning the central nuclear power plant of Gravelines. This very high power level (5400 MW) 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. Surveillance studies concern monitoring of fish populations (larvae and eggs of Sole and Sprat) or crustaceans( shrimps), benthic system (intertidal and subtidal) and pelagic system (hydrology, microbiology, phytoplankton, zooplankton). 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... |

In French Polynesia, the black-lip pearl oyster Pinctada margaritifera has been farmed to produce pearls since the 1980s, forming the basis of a major industry. The sustainability of this activity relies on spat collection in the lagoons. However, pearl oyster spat can be difficult to identify for the evaluation of stock variations. It is especially hard to distinguish Pinctada spp. larvae at a very early stage of development. In the present study, a whole- mount in situ hybridisation (ISH) technique was developed to allow the discrimination of larvae of closely-related pearl oyster species found in the French Polynesian atolls. Using specific ribosomal 16S-DNA sequence data, we were able to successfully differentiate between Pinctada margaritifera and... |

This is the 23th annual surveillance report concerning the Gravelines nuclear power plant. Gravelines, located between Calais and Dunkerque and very high power station (5400 MW) with sixth plants. liegining of electricity production in 1980 reached maximum production in 1986. Surveillance studies concern fisheries, intertidal and subtidal zoobenthos hydrology, microbiology, phytoplankton and zoplankton. Studies concern seasonal variations in natural environment and impact study at outfall of plant. |

Afin de fournir une meilleure idée sur la structure et la dynamique de la communauté des dinoflagellés et leurs relations avec les paramètres environnementaux dans les zones semi-fermées en communication avec le golfe de Tunis, une étude a été réalisée dans les ports puniques de Carthage afin d’estimer les densités et la dynamique des espèces de dinoflagellés ainsi que les variations des concentrations en nutriments, de janvier à juin 2006. Un nombre de 66 espèces de dinoflagellés ont été identifiés dont 14 espèces sont connues pour être nocives et responsables d’efflorescences nuisibles alors que 21 espèces sont connues pour être productrices de toxines. L'analyse statistique nous a permis de révéler des corrélations significatives entre les densités de... |
