Extended Data Fig. 6: Comparison of calculated phytoplankton growth rates across the PRB in carbonate and non-carbonate-dominated regions.
From: Carbonate weathering enhances nitrogen assimilatory uptake in rivers globally
a,b, The growth rate in wet season (a) and dry season (b), respectively. Zero values are excluded in this figure. The diamond scatter, the line inside the box, lines outside the boxes, and the purple and green dots represent the mean value, median value, 1.5 IQR, and the data, respectively. The two-sided Mann–Whitney test is applied to evaluate the difference between carbonate- and non-carbonate-dominated regions, where p < 0.01 represents highly significant, p < 0.05 represents significant, otherwise there is no statistical significance.
