<div><p><strong>Experimental design</strong></p>
<p>Four treatments contrasted high and low temperature and pCO2:<br />
Ambient temperature = 27.5 oC<br />
Ambient pCO2 = 39.0 Pa<br />
High temperature = 30.5 oC<br />
High pCO2 = 86 Pa</p>
<p>Juvenile <em>Seriatopora caliendrum</em> were collected from Hobihu Reef, Nanwan Bay, Taiwan, and kept at the National Museum of Marine Biology and Aquarium (NMMBA), where they were placed randomly into the treatment tanks for incubations lasting 14 days. Corals were exposed to treatments in 8 tanks filled with filtered seawater. Treatments were maintained at a salinity of 33 and were monitored daily for temperature, salinity, irradiance, pH and carbonate chemistry.</p>
<p><strong>Photochemical efficiency: </strong>The effects of temperature and pCO2 on photochemical efficiency were tested by measuring the maximum photochemical efficiency of open RCIIs (Type II reaction centers) in the dark (Fv/Fm) and the effective photochemical efficiency of RCII in the light (deltaF/Fm') using pulse amplitude modulation (PAM) fluorometry.</p>
<p><strong>Photosynthesis-irradiance (P/I) curves: </strong>To test for the effects of pCO2 and temperature on the ability for <em>Symbiodinium</em> to utilize light and perform photosynthesis, net photosynthesis (P^net), determined from changes in O2 concentrations in seawater, was measured under different irradiances using three corals selected randomly from each treatment tank.</p>
<p><strong>Chlorophyll-a concentration and <em>Symbiodinium</em> density: </strong>Chlorophyll-a concentration and <em>Symbiodinium</em> density were determined.</p>

Seriatopora bleaching expt: temperature, salinity, light in tanks
<div><p>We hypothesized that ocean acidification would cause bleaching as defined by decreased photochemical efficiency, reduced photosynthetic capacity and efficiency, depressed chlorophyll a content, and lowered <em>Symbiodinium</em> densities and that these effects would be exacerbated with high temperature.</p>
