Modélisation écosystémique de l'estuaire et du nord du golfe du Saint-Laurent

Abstract : In this study, we used inverse methodology to construct a mass-balance model of the Estuary and northern Gulf of St. Lawrence for the 2006-2010 time period. The whole system was divided into 44 functional groups from phytoplankton and detritus to marine mammals and seabirds, including the main pelagic, demersal, and benthic species. Our overall objective was to determine the community structure and function of the studied ecosystem. Usable information exists on most of the benthic and pelagic communities of the St. Lawrence ecosystem. However, there is no overall description of ecosystem functioning. Food web modelling is an ideal way to describe such an ecosystem by creating an overview of its trophic network. The fists step was to gather and analyse basic data for the different studied groups. Based on these data, an ecosystem model was then constructed. Model results will provide an overall description of community structure, trophic interactions, and the effects of fishing and predation on the vertebrate and invertebrate communities of the ecosystem for the 2006-2010 period.
