Chlorophyll a-based production rates of anatoxin during the June 2019 bioassays. Only Sandusky Bay produced anatoxin in June. (A) Undiluted Sandusky Bay anatoxin concentrations (also see Table S7); (B) undiluted Sandusky Bay biomass-normalized anatoxin concentrations (also see Table S8); (C) 40% dilution Sandusky Bay anatoxin concentrations (also see Table S7); (D) 40% dilution Sandusky Bay biomass-normalized anatoxin concentrations (also see Table S8); (E) Maumee Bay anatoxin production rates under the various nutrient addition treatments at the two locations of T3 compared to T0 (also see Table S9); (F) Maumee Bay biomass-normalized anatoxin production rates under the various nutrient addition treatments at the two locations of T3 compared to T0 (also see Table S10). Error bars are standard error. Significance for (E,F) is from n-factor ANOVA analysis due to unbalanced data sets.
