Environmental and geochemical parameters in the jars.
Figure 1.
Change in volume vs. (A) treatment and (B) aragonite saturation state.
(A) Mean relative change in volume of Mytilus galloprovincialis in two different CO2 treatments (400 µatm vs. 1200 µatm) and 6 temperature treatments (12, 14, 16, 18, 20, and 24°C). Mean is based on mean relative change in volume from each of three replicate jars (N = 3) at each treatment (± SEM). The mean change in volume of each jar is calculated from 5 M. galloprovincialis per jar. (B) Mean change in volume of M. galloprovincialis vs. the mean saturation state of aragonite in each jar.

Figure 2.
The relationship between temperature and the (A) ratio of soft tissue to shell mass and (B) length-corrected shell mass.
Triangles = 400 µatm CO2, Circles = 1200 µatm CO2. Dotted line is the regression line fit to 400 µatm, while the solid line is the regression line fit to 1200 µatm. Data points represent the means of independent jars.

Figure 3.
Thermal performance curves for each CO2 treatment.
Curves are fit by a quadratic function. Triangles = 400 µatm CO2, Circles = 1200 µatm CO2. Dotted line is the curve fit to 400 µatm, while the solid line is the curve fit to 1200 µatm. Data points represent the means of independent jars.
Figure 4.
Variation in feeding rates among temperature and CO2 treatments.
Mean change in fluorescence of microalgal mixture in seawater from two different CO2 treatments (400 µatm vs. 1200 µatm) and 6 temperature treatments (12, 14, 16, 18, 20, and 24°C) per hour. Mean is based on mean change in fluorescence from each of three replicate jars (N = 3) at each treatment (±SD) after allowing 20 hours for feeding.
