Table 2 Results of statistical analysis of Exact Sum of Squares F-test (non-linear models) and ANCOVA (linear models) examining the effects of the internal N status of the algae (N-replete v/s N-deplete) on the TPCs of the temperature-dependant traits: growth, photosynthesis, Fv/Fm and NR activity, and biochemical parameters of Macrocystis pyrifera.
