In the original publication of this article, the circles were not shown in Fig. 1. The circled data points show statistically significant differences in the relative abundance of Prymnesium parvum (ANOVA, Tukey’s HSD). The correct version of Fig. 1 is provided, where the original graph remains the same and the missing circles have now been included.
