Mean (n = 3)* volumetric productivities of fatty acids (FA) obtained from final harvested biomass samples of the temperature × light cross-gradient visualized as heat-plot: (A) Total FA productivity (mg L⁻¹ Day⁻¹); (B) Stearidonic acid—18:4ω3 (SDA) productivity (mg L⁻¹ Day⁻¹); (C) Eicosapentaenoic acid—20:5ω3 (EPA) productivity (mg L⁻¹ Day⁻¹); (D) Docosahexaenoic acid—22:6ω3 (DHA) productivity (mg L⁻¹ Day⁻¹). *In conditions of low temperature and high light intensities, not all three replications were available (for detail see Fig. 1)
