Interacting effects of CO2 partial pressure and temperature on photosynthesis and calcification in a scleractinian coral
Open accessAbstract
We show here that CO 2 partial pressure (p CO 2) and temperature significantly interact on coral physiology. The effects of increased p CO 2 and temperature on photosynthesis, respiration and calcification rates were investigated in the scleractinian coral Stylophora pistillata. Cuttings were exposed to temperatures of 25°C or 28°C and to p CO 2 values of ca. 460 or 760 μatm for 5 weeks. The contents of chlorophyll c2 and protein remained constant throughout the experiment, while the chlorophyll a content was significantly affected by temperature, and was higher under the ‘high‐temperature–high‐p CO 2’ condition. The cell‐specific density was higher at ‘high p CO 2’ than at ‘normal p CO 2’ (1.7 vs. 1.4). The net photosynthesis normalized per unit protein was affected by both temperature and p CO 2, whereas respiration was not affected by the treatments. Calcification decreased by 50% when temperature and p CO 2 were both elevated. Calcification under normal temperature did not change in response to an increased p CO 2. This is not in agreement with numerous published papers that describe a negative relationship between marine calcification and CO 2. The confounding effect of temperature has the potential to explain a large portion of the variability of the relationship between calcification and p CO 2 reported in the literature, and warrants a re‐evaluation of the projected decrease of marine calcification by the year 2100.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
