Context

This PhD focuses on marine coastal ecosystems. In such ecosystems, fauna might be of very high diversity in terms of taxa, individual sizes and functional groups. Organisms might have different forms through their life cycle. Identifying the major groups that can form homogeneous compartments and the links between those is an important issue in marine ecosystem theoretical modelling.
Moreover, coastal ecosystems are characterised by the significant link between pelagic and benthic fractions as well as the complexity of the species and functional groups. The modelling study should therefore include strong coupling between benthic and pelagic organisms.

Aims

Elaborate a bentho-pelagic coupled model of the Marennes-Oléron Bay taking into account the physical environment such as temperature, tide and hydrodynamics (VASIREMI project).
