Fig 5. Model (1a) dynamics with pollinator adaptive preferences.

Population densities (units in left axes) are represented by: green squares = plant 1, red diamonds = plant 2, pink circles = pollinator. Pollinator preference for plant 1 (u₁, units in right axes) is represented by the black line. Initial population densities in all panels P₁(0) = P₂(0) = 25, A(0) = 1. Preferences in (a) are given by the ESS Eq (11). Preferences in (b) and (c) are given by the replicator Eq (4) with ν = 1, 0.25 respectively and u₁(0) = 0.999. Parameters as in Table 1, with K_i = 50, c_i = 0.
