Autores: Travers, Morgane.
Overfishing and climate change are now recognized to have important effects on marine ecosystem functioning but uncertainties remains about their combined effects. Using a modelling approach this thesis aims at assessing how the top-down effects of fishing and the bottom-up effects of climate combine themselves within the food web. A preliminary review highlighted the lack of end-to-end model applicable as it stands to our study case - the southern Benguela - and suitable to study the combined effects of fishing and climate. Coupling the plankton model ROMS-N2P2Z2D2 and the fish model OSMOSE appeared as an innovative method allowing to develop an appropriate tool meeting our objectives. The importance of two-way coupling via the predation process is first...
