Figure 4
Transition from the MWC to the Sel'kov mechanism as described by Eq. 9. Upper panels show the Hill coefficient n H (Eq. 11) as a function of the steady state activator concentration γ s while the lower panels show the respective phase diagram. The solid line (TH) separates wave patterns (grey shaded area) from stationary Turing patterns. The dashed line indicates the transition from inward (dark grey) to outward (light grey) propagating waves while the dash-dotted line marks the Benjamin-Feir (BF) instability and the occurrence of spatio-temporal chaos. The dotted line marks the location of the maximum of the Hill coefficient. Other parameter: L = 103, n = 8, q = 1.
