Effect of pH and/or temperature on coral nutrient uptake rates.

<p>Effect of a 10-day exposure to lowered pH and/or elevated temperatures on ammonium (<b>A</b>, <b>D</b>, <b>G</b>), nitrate(<b>B</b>, <b>E</b>, <b>H</b>), and phosphate (<b>C</b>, <b>F</b>, <b>I</b>) uptake rate of <i>S. pistillata</i> nubbins. Corals were incubated either under 3 different pH_T at 26°C (<b>A</b>, <b>B</b>, <b>C</b>), under 3 different temperatures at pH_T = 8.1 (<b>D</b>, <b>E</b>, <b>F</b>), or under 3 different pH_T at 33°C (<b>G</b>, <b>H</b>, <b>I</b>). Data are presented as mean ± SE of 5 nubbins per treatment. Stars indicate treatments significantly different from the control (pH_T = 8.1 for <b>A</b>, <b>B</b>, <b>C</b>, <b>G</b>, <b>H</b>, <b>I</b>; T = 26°C for <b>D</b>, <b>E</b>, <b>F</b>).
