Data are the ranges of mean values for two chemostats at each level of C:P_supply. The p-value associated with the one-way ANOVA of each parameter vs. C:P_supply is denoted by

^*p < 0.05,

^**p < 0.01, and

^***p < 0.001. Underlining denotes samples with insufficient replication for ANOVA, italics denote strains where fewer than 10 chemostats were within detection limits for the parameter.
