The effect of different combinations of (a) mortality and damage functions on (b) optimal reproduction and (c) reproductive value, in a situation where instantaneous mortality depends on reproductive rate r but not on damage level x. Functions f(r) = r² (a; thin line) and g(r) = 0.1 + r² (a; bold line) are used as mortality and damage functions in three combinations to produce the results of case 1 (solid line) case 2 (dashed) and case 3 (dotted) in (b) and (c). Case 1: m(r) = f(r), D(r) = g(r); case 2: m(r) = g(r), D(r) = f(r); case 3: m(r) = D(r) = f(r).
