Extended Data Fig. 1: Population compositions in the ASSs when the average body size at habitat switch equals 0.25.

From: Ecological changes with minor effect initiate evolution to delayed regime shifts

Extended Data Fig. 1

The two ASSs correspond to low (solid line) and high biomass levels (dashed line) in the nursery habitat, and to high (solid line) and low biomass levels (dashed line) in the adult habitat. These alternative stable population compositions represent the population structure approximately at time 260 in Fig. 2 (before the regime shift in Fig. 2) and approximately at time 340 in Fig. 2 (after the regime shift in Fig. 2). The regime shift observed in Fig. 2 leads to a decrease in population density in the nursery habitat (green region) and an increase in population density in the adult habitat (blue region), mainly as a consequence of an increase in the density of immature individuals (smaller than the size at maturation). This increase in density of immature individuals in the adult habitat results in increased competition in this habitat that produces a reduction of 32% in the maximum asymptotic body size after the regime shift (reduction from 3.71 to 2.52). Parameter values as in Fig. 2.
