Fig 7. Boxplots of intracellular anatoxin-a and microcystin concentrations from cyanobacterial mats dominated by Anabaena (n = 116) or Phormidium (n = 62) collected in 2014 and 2015.
Only samples with cyanotoxin concentrations above the detection limit are included in the boxplots. For anatoxin-a, there were 69 Anabaena-dominated and 36 Phormidium-dominated samples above the detection limit, and for microcystin there were 31 Anabaena-dominated and 36 Phormidium-dominated samples above the detection limit. The boxplots are plotted on a log10 scale, and the box represents the 25th percentile, median, and 75th percentile of the data, the whiskers extend up to 1.5x the interquartile range, and points beyond the whiskers are plotted individually.
