The F and P values for two-way ANOVA are presented (n = 32 ± 1 for treatment groups and n = 33 ± 4 for temperature groups), with bold text indicating significance after false-discovery rate correction for multiple comparisons. Significant differences between groups were evaluated post hoc with Welch's t-tests (also see Results section), and are indicated by different superscript letters.
