Fig. 6. Phase diagrams for the ecosystem's dynamics at a given level of resource complementarity and increasing interspecies competition, γi. Dynamics in each diagram are characterized by dx/dt > 0 (< 0) left (right) of the green line, and dw/dt > 0 (< 0) below (above) the red line. Blue lines indicate saddlepaths. The upper diagram displays the case of independent species (γx = γw = 0). Competition occurs in the middle (γx = γw = 0.25) and increases in the lower (γx = γw = 1.25) diagram. Parameter values for all diagrams: ρx = ρw = 0.5, κx = κw = 1, νx = νw = 1, α = 0.6, σ = 0.4, n = 1.
