**Figure A2.** Species biomass (g 100 m<sup>−</sup>2) predicted along the salinity gradient for each season investigated. The current salinity and the three scenarios of salinity reduction are highlighted. Dashed lines indicate the standard error of the prediction.

**Figure A3.** Guild biomass (g 100 m<sup>−</sup>2) predicted along the salinity gradient for each season investigated. The current salinity and the three scenarios of salinity reduction are highlighted. Dashed lines indicate the standard error of the prediction. Guilds are abbreviated as follows. ES: estuarine resident species; ESs: solely estuarine resident species; MED: marine estuarine-dependent species; Bmi: microbenthivores; DV: detritivores; Bma: macrobenthivores; HZ: hyperbenthivores-zooplanctivores; HP: hyperbenthivores-piscivores; OV: omnivores.
