Model stability vs. the proportion of predator diet comprised of top-down controlled prey species.
(A) Total predator consumption is held constant, so that the equilibrium consumption of predators on each prey species is variable. Predator consumption is modeled with a saturating functional response. (B) Same as A, but the parameters of each prey species production function is adjusted so that interaction strengths are held constant. Satiation is modeled as a non-saturating functional response. (C) Same as B, but with a saturating functional response. Model parameters: m = 0.2; µ = 0.1; C1 + C2 = 0.2; Cmax (if used) = 0.8; P* = 1, lines are as defined in Figure 1 A and B.
