FIGURE 3.

Average (A) nitrogen-specific fixation rates and (B) carbon-specific fixation rates normalized to PON and POC, respectively, of Trichodesmium GBRTRLI101 in five constant and variable temperature treatments under two P conditions (10 and 0.2 μmol/L) in summer and winter experiments. Values and error bars, respectively, represent the means and the standard deviations of triplicate cell cultures under each treatment. The letters represent the significant differences based on the grouping results of the Tukey multiple comparison among ten temperature ×P treatments.
