  abstract = {{W}e developed an ecological model to characterize the structure and functioning of the marine continental shelf and slope area of the northwestern {M}editerranean {S}ea, from {T}oulon to {C}ape {L}a {N}ao ({NWM} model), in the early 2000s. {T}he model included previously modeled areas in the {NW} {M}editerranean (the {G}ulf of {L}ions and the {S}outhern {C}atalan {S}ea) and expanded their ranges, covering 45,547 km(2), with depths from 0 to 1000 in. {T}he study area was chosen to specifically account for the connectivity between the areas and shared fish stocks and fleets. {I}nput data were based on local scientific surveys and fishing statistics, published data on stomach content analyses, and the application of empirical equations to estimate consumption and production rates. {T}he model was composed of 54 functional groups, from primary producers to top predators, and {S}panish and {F}rench fishing fleets were considered. {R}esults were analyzed using ecological indicators and compared with outputs from ecosystem models developed in the {M}editerranean {S}ea and the {G}ulf of {C}adiz prior to this study. {R}esults showed that the main trophic flows were associated with detritus, phytoplankton, zooplankton and benthic invertebrates. {S}everal high trophic level organisms (such as dolphins, benthopelagic cephalopods, large demersal fishes from the continental shelf, and other large pelagic fishes), and the herbivorous salema fish, were identified as keystone groups within the ecosystem. {R}esults confirmed that fishing impact was high and widespread throughout the food web. {T}he comparative approach highlighted that, despite productivity differences, the ecosystems shared common features in structure and functioning traits such as the important role of detritus, the dominance of the pelagic fraction in terms of flows and the importance of benthic pelagic coupling.},
