Chaos in synthetic microbial communities
Fig 5
Parameters kA1 and D can be tuned to control transitions between chaotic, oscillatory and stable states.
The fixed parameter values are shown in Table 2. A Map showing how different combinations of kA1 and D change population behaviour. The grid fill colour corresponds to the maximum Lyapunov exponent measured, the grid outlines indicate the approximate classification where green is stable, yellow is oscillatory, red is chaotic and white is extinction. B Bifurcation diagram showing the community states visited for different values of kA1. C Bifurcation diagram showing the community states visited for different values of D. D Real-time ramp down tuning of kA1, moving the system from a chaotic state to a stable steady state. E Real-time ramp up tuning of D, moving the system from a chaotic state to a stable steady state.
