Phaeocystis antarctica physiological changes. Physiological response of P. antarctica to variability in light, Mn, and Fe. High light (HL) was 230 µE/m2/s1, intermediate (IL) was 70 µE/m2/s and low (LL) was 25 µE/m2/s. Each dot represents the value measured in one biological replicate for either chlorophyll per cell, Fv/Fm, growth rate, or forward side scatter—a flow cytometry-derived parameter that scales with cell size. Differences between physiological response were analyzed via analysis of variance (ANOVA) and Tukey’s HSD (honestly significant difference) post hoc tests. Letters denote significant differences in two separate tests: metal replete with different light levels (italics, gray, columns 1, 2, 3), and low light with different metal concentrations (columns 4, 5, 6, 7). If the ANOVA indicated significant differences in means across treatments, pairwise differences were tested for and visualized with different letters above each treatment: treatments that have the same letter are not significantly different. n = 3 biologically independent samples per treatment.
