Extended Data Fig. 3: Long-term stability of the system.
From: Ecological changes with minor effect initiate evolution to delayed regime shifts
Population biomass and food resource densities in the nursery and adult habitat and selection gradient as a function of body size at habitat switch after a decrease in mortality when the evolutionary endpoint occurs a) in one of the alternative stable ecological equilibrium resulting in a single regime shift (dynamics shown in Fig. 4a) and b) in the unstable equilibrium resulting in repeated delayed regime shifts (dynamics shown in Fig. 4b). Ecologically stable (solid lines) and unstable (dashed lines) equilibrium values are indicated with black lines as well as minimum and maximum densities during oscillatory dynamics (dotted lines). The direction of selection is indicated with thick arrows (orange when negative and blue when positive) and ecological dynamics with double vertical arrows (yellow). The evolutionary endpoint is indicated with a circle (open circle in case it corresponds to an unstable ecological equilibrium, filled circle if it correspond to a stable ecological equilibrium). The direction of selection (bottom plots) is positive at low values of the trait (blue shaded area), negative at high values (pink shaded area) and either negative or positive at intermediate values of the trait (mixed shaded area), depending on which of the two ASSs the population is in. Parameter values as in Fig. 4.
