Dynamics of microbial activities and the ratio of LNA activities to HNA activities in the surface (red) and bottom (blue) layers of the Aquatron macrocosm.

Caption

(a) Prokaryotic gross growth rate for HNA (PGG-H). (b) Prokaryotic gross growth rate for LNA (PGG-L). (c) The ratio of PGG-L to PGG-H (PGG-L/PGG-H). (d) Protozoan grazing-mediated HNA mortality rate (PMM-H). (e) Protozoan grazing-mediated LNA mortality rate (PMM-L). (f) The ratio of PMM-L to PMM-H (PMM-L/PMM-H). The standard deviation is represented by error bars. Regression analysis was performed separately for each data set during P1 (days 0–16) and P2 (days 16–73), and the regression results (R2 and P) are shown next to the regression curves, with gray areas representing confidence intervals.
