Fig. 4: Boxplot of the daily CO2-based cell-specific division rates.
From: Small phytoplankton contribute greatly to CO2-fixation after the diatom bloom in the Southern Ocean
Each dot corresponds to the division rate of a single-cell measured with NanoSIMS for cells <20 µm (a, b) or with SIMS for diatoms >20 µm (c). Diamonds indicate mean division rates and inactive cells are colored in black. Significant differences (pairwise Mann–Whitney test with p < 0.05) in division rates between stations (a) or between size-groups on- and off-plateau (b) are indicated by letters above the boxplots (ranked by alphabetical order from highest to lowest division rates). Outliers correspond to the larger points.
