Fig. 2: Correlations between nitrite and ammonia oxidation rates and nitrite concentrations across investigated stations.
From: Single cell analyses reveal contrasting life strategies of the two main nitrifiers in the ocean
a Correlation between nitrite oxidation rate and nitrite concentration. b Correlation between ammonia oxidation rate and nitrite concentration (reproduced from ref. 31). The black line is the linear regression, R2 was calculated on the basis of Pearson correlations, and was significant (two-sided t-test, t = 8.002, DF = 7, P = 9.10 × 10−5). Error bars represent standard error of the process rates calculated from slopes across all time points and replicates.
