Fig. 2. — Emergence of multimodal body-size distributions. Steady-state distributions of the model (Eqs. 1 and 2) are demonstrated when the selection strength (s) is varied. When competition is deterministic, the distribution is smooth (A). However, when competition is sufficiently stochastic, multimodal patterns emerge (B–D): peaks appear near the singularity at , followed by smooth tails on the right. The distance between consecutive peaks is of the order of , and the width of the peaks is affected by the mutation rate () (see also Fig. S1).
