<div><p>Changes in dissolved oxygen in coral and algal samples were monitored during 30 min incubations with PreSens dipping oxygen optodes (PSt3) connected to Fibox 3 transmitters (Precision Sensing GmbH, Germany). The oxygen probes were calibrated every morning using a 2-point calibration in water-saturated air (100%) and anoxic seawater created by supersaturating seawater with sodium dithionite (Na2S2O4). Temperature was held constant during incubations by circulating water in a water jacket surrounding the incubation chamber. Chambers were positioned on magnetic stir plates, and seawater flow inside the chambers was regulated with magnetic stir bar that created vigorous and turbulent water motion. A similar irradiance to that used during incubations (i.e. 700 mmol quanta m22 s21) was maintained while the organisms were in the acrylic chambers by placing an LED lamp (75-W, Sol LED Module, Aquaillumination) above the chambers. On the same day that net photosynthesis was measured, and after at least 2 h of darkness (i.e. after 20:00 h), dark respiration was measured using an identical procedure to that used for photosynthesis, except the chamber was kept in darkness.</p></div>
