Effect of different (a) mortality functions on (b) optimal reproduction and (c) reproductive value, in a situation where instantaneous mortality depends on damage level x but not on reproductive rate r. Mortality functions are: m(x) = 0.1 (solid line); m(x) = 0.1 + r2 (dashed); m(x) = e5x−2.5/(1 + e5x−2.5) (stippled). Damage function: D(r) = r2.
