Table 2. Statistical evaluation of metabolite changes of carbohydrates and amino acids at three salinities across four Symbiodinium strains.

Symbiodinium strain and salinity level are fixed factors, and strain*salinity serves as the interaction effect. Two-way ANOVA was used. Significance levels at P < 0.01 are in boldface.
