Fig. 5: Growth of Planktothrix and Pseudanabaena under culture conditions including 5 levels of light doses.

a and field environment of QCS Reservoir from 2013 to 2015. b Growth yield of Planktothrix and Pseudanabaena within stationary phase (day 15–35) was used. Source data of Planktothrix growth is from34. Boxplot is Tukey style, where the bottom and top of the boxes denote the 25% and 75% quantiles, the ends of whiskers represent minimum and maximum cell densities with outliers removed, and the bands in the boxes denote the median cell densities. The zones colored purple and green denote the 90% quantile niche spaces (water temperature & pre-week PAR) of Planktothrix and Pseudanabaena, respectively. The red circles with a letter inside (J–D = January–December) denote the environmental conditions (represented by mean water temperature and mean pre-week PAR) in the corresponding month.
