  abstract = {{T}he {M}editerranean {S}ea has been defined "under siege" because of intense pressures from multiple human activities; yet there is still insufficient information on the cumulative impact of these stressors on the ecosystem and its resources. {W}e evaluate how the historical (1950-2011) trends of various ecosystems groups/species have been impacted by changes in primary productivity ({PP}) combined with fishing pressure. {W}e investigate the whole {M}editerranean {S}ea using a food web modelling approach. {R}esults indicate that both changes in {PP} and fishing pressure played an important role in driving species dynamics. {Y}et, {PP} was the strongest driver upon the {M}editerranean {S}ea ecosystem. {T}his highlights the importance of bottom-up processes in controlling the biological characteristics of the region. {W}e observe a reduction in abundance of important fish species (similar to 34%, including commercial and noncommercial) and top predators (similar to 41%), and increases of the organisms at the bottom of the food web (similar to 23%). {E}cological indicators, such as community biomass, trophic levels, catch and diversity indicators, reflect such changes and show overall ecosystem degradation over time. {S}ince climate change and fishing pressure are expected to intensify in the {M}editerranean {S}ea, this study constitutes a baseline reference for stepping forward in assessing the future management of the basin.},
