Supplementary Figure S1: scenarios with logistic growth from Variability in life-history switch points across and within populations explained by Adaptive Dynamics

Scenarios for time of maturation under different juvenile initial sizes computed with logistic growth function w(τ)=g(w₀,τ)= w₀w_K exp(rτ)/(w_K+w₀(exp(rτ)-1)). Orange interval: internal Evolutionary Stable Strategy (ESS) 0<τ<1. Parameters as in figure 4a in the main text except w_K=10. Dark green interval: branching point (within-population variability). Light green interval: either branching point or boundary strategy τ=0 (across- and within-population variability). Red interval: direct development. Solid line: convergence stable equilibria (attracting strategies). Dashed line: convergence unstable equilibria (repelling strategies). Thick line: convergence stable but evolutionary unstable equilibria (branching points). TC: transcritical bifurcation. BR: branching bifurcation (B=0 in equation (6) in the main text), turning selection disruptive. SN: saddle-node bifurcation.;Model implementation
