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...

Phytoplankton size distribution and community structure: influence of nutrient input and sedimentary loss (2007)

Pannard, Alexandrine, Bormans, Myriam, Lefebvre, Sebastien, Claquin, Pascal, Lagadeuc, Yvan

This study examines the effects of nutrient availability and sedimentary loss on the dynamics of freshwater phytoplankton, from the physiological state at the cellular level to the competition issue...

Application of a dynamic energy budget model to the Pacific oyster, Crassostrea gigas, reared under various environmental conditions (2006)

POUVREAU, Stephane, BOURLES, Yves, LEFEBVRE, Sebastien, GANGNERY, Aline, ALUNNO-BRUSCIA, Marianne

The Dynamic Energy Budget (DEB) model (Kooijman, S.A.L.M., 1986. Energy budgets can explain body size relations. J. Theor. Biol. 121, 269¿282; Kooijman, S.A.L.M., 2000. Dynamic Energy and Mass...

The trophic risk: trophic characteristics and heterogeneity of the food supplies, in relation to oyster mortality (2004)

ROPERT, Michel, LEFEBVRE, Sebastien, SOLETCHNIK, Patrick, BLIN, J. L., FAURY, Nicole, STRUSKI, Caroline

The "trophic risk" has been demonstrated in the bioenergetic model developed in vivo and based on various diet conditions similar to those of different types of oyster culture basins (eutrophic,...
