TABLE 1.
Pearson’s correlations generated for the relative proportion of the Microcystis population that had a complete, partial, or absent mcy operon as well as the ratio of C1/B1 variants against the environmental variables pH, nitrate concentration, and ammonium concentration (n = 15)
| mcy genotype category | pH |
Nitrate concn (mg/L) |
Ammonium concn (μg/L) |
