Table 2.

Multi-predictor PGLS results of PUR as the dependent variable and phycobiliprotein maximum absorption peak wavelength (phycobiliprotein max. abs. peak), phycobiliprotein concentration per cell (pg cell⁻¹), and the additive value of the absolute concentrations per cell (pg cell⁻¹) of alloxanthin, α-carotene, chlorophyll a and chlorophyll c₂ (non-phycobiliprotein pigments) as predictors. (All values were log₁₀ transformed before analysis (log). *Significant at p < 0.05; ***significant at p < 0.001.)
