Figure 4
Monoculture and competition experiments between the toxic and non-toxic strain in a light-limited chemostat. (a, b) Population density (expressed as biovolumes) and light intensity penetrating through the chemostat (Iout) in monoculture experiments of (a) the toxic strain Microcystis CYA140, and (b) the non-toxic strain Microcystis CYA43. (c) In competition, the non-toxic strain Microcystis CYA43 displaces the toxic strain Microcystis CYA140. (d) Total microcystin concentration in the competition experiment (error bars indicate s.d.). Symbols represent chemostat data, lines show the model predictions. Parameter values are given in Tables 1 and 2. The chemostat data in this figure are from Kardinaal et al. (2007b).
