a Chlorophyll a-based accumulation rates (d−1) of all (total), the small (0.2–2 μm) and the large (>2 μm) cells (n = 3), b net growth rate of each picoeukaryote group (three subgroups P1–P3) determined via flow cytometry (n = 6) and c net growth rate of Chaetoceros sp., Fragilariopsis sp., Pseudo-nitzschia sp. and Phaeocystis antarctica determined via light microscopy (n = 3). All parameters were estimated at the end of the experiment from the community sampled at station East (BIO3) after exposure to different Fe and Mn availabilities (Supplementary Fig. 2). Values represent the mean ± SD. Different letters indicate significant differences between treatments (p < 0.05).
