From: Microcosm experimental evidence that habitat orientation affects phytoplankton-zooplankton dynamics

Cell density (means ± 1 s.d., n = 6) of Chlorella pyrenoidosa in the absence (A,B) and presence of grazers [Daphnia magna (C,D) or Moina micrura (E,F)] under three levels of habitat orientation and two levels of spatial scale. Different letters indicate significant differences among treatments on a specific day. Multiple comparisons of means were performed using Tukey’s test at the 0.05 significance level. Figure 5 was created using Microsoft Excel 2016.
