In the original article, the light cycle was indicated as 12:12 h light:dark. However, this was in error and the actual cycle was 10:14 h light:dark. Additionally, there was a conversion error in calculating net production and LEDR as depicted in Figs. 2 and 3. This was strictly a conversion error and has no impact on the statistical analysis or interpretation of the data. The corrected panels from Fig. 2 and 3 are as follows.(figure presented)Average (± 1 SE) net photosynthesis cell− 1 (top) and LEDR (bottom) at two pCO2 levels, nutrient concentrations (LN = low nutrients, HN = high nutrients) and 26.5 °C (light bars) or 31.5 °C (dark bars). For each panel, the designations ‘temp’, ‘pCO2′ and ‘nutr’ indicate significant temperature, pCO2, nutrient concentration, or their interactive effects (multifactorial ANOVA results in Table S1). n = 5–6 per average.
