Effects of Moderate Heat Stress and Dissolved Inorganic Carbon Concentration on Photosynthesis and Respiration of Symbiodinium Sp (Dinophyceae) in Culture and in Symbiosis
The influence of temperature and inorganic carbon (Ci) concentration on photosynthesis was examined in whole corals and samples of cultured symbiotic dinoflagellates (Symbiodinium sp.) using combined measurements from a membrane inlet mass spectrometer and chl a fluorometer. In whole corals, O2 production at 26°C was significantly limited at Ci concentrations below ambient seawater (∼2.2 mM). Further additions of Ci up to ∼10 mM caused no further stimulation of oxygenic photosynthesis....[Show more]
