Dependence of systems dynamics on dilution rate (D). (A) Experimental dynamics of predator and prey populations at different D in the microchemostat: for the pair of predator (MG1655) and prey (Top10F'). (B) For the pair of predator (Top10F') and prey (Top10F'). (C) Bifurcation diagram of oscillatory period versus D. The inset is the oscillation period versus D. Qualitatively different systems dynamics (sustained and damped oscillations, and steady state) can be obtained by the variation of D. These experiments were carried out at IPTG=50 muM.
