| Summary: | Corallinales (Rhodophyta) are high Mg-calcite macroalgae and are considered among the most vulnerable organisms to ocean acidification (OA). These sensitive species play fundamental roles in coastal systems as food source and settlement promoters as well as being involved in reef stabilization, and water carbonate balance. At present only a few studies are focused on erect calcifying macroalgae under low pH/high pCO2 and the contrasting results make difficult to predict the ecological consequences of the OA on the coralline algae. In this paper the physiological reasons behind the resistance of Jania rubens, one of the most common calcareous species, to changing ocean pH are analysed. In particular, we studied the photosynthetic and mineralogical response of J. rubens after a three-week transplant in a natural CO2 vent system. The overall results showed that J. rubens could be able to survive under predicted pH conditions even though with a reduced fitness; nevertheless physiological limits prevent the ... : Supplement to: Porzio, Lucia; Buia, Maria-Cristina; Ferretti, Viviana; Lorenti, Maurizio; Rossi, Manuela; Trifuoggi, Marco; Vergara, Alessandro; Arena, Carmen (2018): Photosynthesis and mineralogy of Jania rubens at low pH/high pCO2: A future perspective.
