Pinctada margaritifera responses to temperature and pH: Acclimation capabilities and physiological limits

Under the current temperature regime (black line; dotted line is the confidence interval at 5%), pearl oysters spends 121 days above their thermal optimum (blue line). Under the Representative Concentration Pathway (RCP) scenarios 2.6 (+1 °C), this would be 210 days (yellow), 252 days under the RCP 4.5 (+1.5 °C; orange) and 365 days under the RCP8.5 (+2.5 °C; red).149
