Chapelle, Annie / Menesguen, Alain / Deslous-paoli, Jean-marc / Souchu, Philippe / Mazouni, Nabila / Vaquer, André / Millet, Bertrand - 2000An ecosystem model based on nitrogen cycling and oxygen has been developed for the Thau lagoon. It takes into account the specific features of this Mediterranean lagoon, a semi-confined system with watershed inputs and oyster farming. The ecosystem model uses currents calculated by a two-...Contributeur (s):

Plus, Martin / Chapelle, Annie / Lazure, Pascal / Auby, Isabelle / Levavasseur, G / Verlaque, M / Belsher, Thomas / Deslous-paoli, Jean-marc / Zaldivar, J / Murray, C - 2003A three-dimensional model coupling physical and biological processes for the whole Than lagoon (Mediterranean coast of France) was developed in order to assess the relationships between macrophytes and the oxygen and nitrogen cycles. Ten species have been inserted as forcing variables in the model...Contributeur (s):

The primary production and the respiration of Zostera noltii beds in the Thau lagoon were studied by means of the benthic bell jar technique, Concurrently, environmental data (temperature, light and nutrients) as well as morphological data of seagrass meadows (leaf width and height, density of...Contributeur (s):

Plus, Martin / Chapelle, Annie / Menesguen, Alain / Deslous-paoli, Jean-marc / Auby, Isabelle - 2003A numerical deterministic model for a seagrass ecosystem (Zostera noltii meadows) has been developed for the Thau lagoon. It involves both above- and belowground seagrass biomasses, nitrogen quotas and epiphytes. Driving variables are light intensity, wind speed, rain data and water temperature....Contributeur (s):

Mazouni, Nabila / Gaertner, J / Deslous-paoli, Jean-marc - 2001This study was based on in situ experiments conducted in a shellfish lagoon (Thau, France) to determine the interactions between suspended oyster Crassostrea gigas Thunberg cultures and their environment at a seasonal scale. Three groups of descriptors were considered simultaneously during the...Contributeur (s):

A detailed study of vegetative and reproductive phases of several populations of a common species of Ulva from Thau Lagoon (France, Mediterranean Sea) showed that the material is in good agreement with Asiatic Ulva pertusa Kjellman. Since October 1994, the date of its first observation in Thau...Contributeur (s):

Plante Cuny, Marie-reine / Plante, Raphaël / Mazouni, Nabila / Fontaine, Marie-france / Souchu, Philippe / Deslous-paoli, Jean-marc / Grenz, Christian - 1998Measurements of oxygen fluxes at the water-sediment interface (transparent and opaque enclosures) were made on bare sediments inhabited by microphytes on the one hand, and on sediments diversely colonized by macrophytes (macroalgae and seagrasses) on the other hand. Five stations, typical of...Contributeur (s):

The impact of suspended oyster culture (Crassostrea gigas, Thunberg) on oxygen and nutrient fluxes has been studied in situ, in a coastal lagoon (Thau, France), during a seasonal cycle. On the first plan of the multiple factorial correspondences analysis (MCA), seasons were well discriminated. The...Contributeur (s):

Souchu, Philippe / Vaquer A, André / Collos, Yves / Landrein, Sonia / Deslous-paoli, Jean-marc / Bibent, Bertrand - 2001Thau lagoon is a Mediterranean shellfish ecosystem with large biomasses of oysters growing in waters with high residence time due to low tidal ranges, The influence of filter feeders (oysters and their epibiota) on the spatial distribution of particulate and dissolved compounds in the water column...Contributeur (s):

Deslous-paoli, Jean-marc / Heral, Maurice / Masse, H - 1983An energy budget has been evaluated for a natural population of Crepidula fornicata living at low water of spring tides in the oyster farming basin of Marennes-Oleron. This budget of production was estimated according to the position along the chain. The average biomass for an individual...Contributeur (s):

Heral, Maurice / Razet, Daniel / Deslous-paoli, Jean-marc / Berthome, Jean-paul / Garnier, J. - 1982Four seasonal compaigns providing a sampling of 15 stations each followed during half a tide cycle, i.e. 120 water samples permit the definition of the main hydrobiological features of Marennes-Oleron Bay: salinity and turbidity, phytoplanktonic biomasses, ATP concentrations. The authors suggest...Contributeur (s):

Deslous-paoli, Jean-marc - 1981A bibliographic review has been made on the toxicity of ten metals for some marine larvae of commercial interest. We have classified, according to toxicity, organic salts of tin, mercury, silver, copper, zinc, nickel, lead, cadmium, chromium and manganese. Some synergistic effects of metals,...Contributeur (s):

Deslous-paoli, Jean-marc / Zanette, Yvan / Heral, Maurice / Masse, Henri / Garnier, Jacqueline - 1981The breeding of Pacific oysters Crassostra gigas, in non tidal ponds, before commercialization, brings about an improvement of the shell and of the quantity and quality of the tissues. In fact, the Berthome's indice (1978) moves from 1.36 in June to 0.68 December, and the density of the shell...Contributeur (s):

Deslous-paoli, Jean-marc / Heral, Maurice / Berthome, Jean-paul / Razet, Daniel / Garnier, Jacqueline - 1981In summer 1979, the natural reproduction of oysters Crassostrea gigas Thunberg, in Marennes-Oleron basin, produced a large number of juveniles which was not the case in summer 1981. If one compares the evolution of the main constituents of the flesh, one can see that, at the beginning of August,...Contributeur (s):

The biodeposition was quantified on the field with sediment traps. All over the year, the biodeposition was the lowest for Crepidula fornicata. Mytilus edulis rejected more biodeposits during winter, and Crassostrea gigas during spring and autumn. The percentage of organic matter sonsumed and...Contributeur (s):
