Modelling the influence of environmental factors on the physiological status of the Pacific oyster Crassostrea gigas in an estuarine embayment; The Baie des Veys (France) (2009)

GRANGERE, Karine, MENESGUEN, Alain, LEFEBVRE, Sébastien, BACHER, Cedric, POUVREAU, Stephane

It is well known that temporal changes in bivalve body mass are strongly correlated with temporal variations in water temperature and food supply. In order to study the influence of the year-to-year...

Ecophysiological response of oyster Crassostrea gigas to the spatio-temporal variability of environmental factors : use of an ecological model (2009)

GRANGERE, Karine

The spatial and temporal variability in biotic and abiotic environmental factors influence the ecophysiological response of bivalves (growth, reproduction and survival). In this study, the...

On the interest of using field primary production data to calibrate phytoplankton rate processes in ecosystem models (2009)

GRANGERE, Karine, Lefebvre, Sebastien, MENESGUEN, Alain, Jouenne, Fabien

In many ecosystem models based on empirical formulations, parameters generally are calibrated in order to achieve the best fit between measured and simulated chlorophyll a standing stocks. An...

Invasive mollusks of shellfish watershed of coastal English Channel - Atlantic : genetic diversity and structure of invasive populations, competition with indigenous taxa, risk management for ecosystems and shellfish culture (2006)

BACHELET, Pierrre, DE MONTAUDOUIN, Xavier, DESCLAUX, C., MAIRESSE, G., RAIGNE, H., RANDRIAMBAO, K., ...

Shellfish areas usually receive a large number of introduced species. During the present project, we specially focused on 4 marine benthic molluscs introduced in shellfish areas along the Channel and...

Possibilities to prevent Crassostrea gigas oyster summer mortality in France (2006)

SAMAIN, Jean-Francois, ROPERT, Michel, BEDIER, Edouard, SOLETCHNIK, Patrick, MAZURIE, Joseph, LE COZ, Florence, ...

Summer mortality has been reported in the Pacific oyster, Crassostrea gigas, for many years in Japan, US and Europe. It affects both adults and juveniles and the causes of this phenomenon are...

The "Freshwater" risk: study of the working sites of the Bay of Veys and of the Marennes Oléron Bay (2004)

SOLETCHNIK, Patrick, ROPERT, Michel, GRANGERE, Karine, MUNARON, Dominique, STRUSKI, C.

The role of freshwater is more difficult to comprehend. It might act as a detrital organic matter "vector" (during floods) or an anthropic waste "vector" (toxic molecules from agriculture or other...
