(a) Invasion speed as a function of the native competitor's carrying capacity (1/αRR) and the invader's intrinsic growth rate (rI) for model 1. The bold and dashed white lines denote where Epred = Ecomp and E0 = Ecomp, respectively. Parameter values used are αIR = 0.005, e = 0.5, β = 0.01, DI = 0.25. Invasion speed for model 2 as a function of (b) the native's conversion efficiency of the resource (ɛR) for three values of the invader's attack rate on the resource (γI): 1/300 (thin line, Ecomp < Epred), 1/150 (dashed line, Ecomp = Epred) and 1/75 (thick line, Ecomp > Epred), and (c) the native's attack rate on the resource (γR) for two values of γI. The horizontal lines show the invasion speed in the absence of the native competitor, and A marks the point where Epred = Ecomp. Parameter values used are rH = 10, K = 1000, γR = β = 0.01, ɛR = ɛI = 0.75, μI = μR = DI = 1, e = 0.5.
