Consumer-Resource Dynamics: Quantity, Quality, and Allocation
Figure 4
Consumer mean biomass density (black: scale 1 = 6,000 units) and its standard deviation σ (red: scale 1 = 6,000 units) averaged over a 1000 year period for the allocation parameter u switching between umin = 0.5-Δu (X≤Xswitch) and umin = 0.5+Δu (X>Xswitch) with the conversion deviation efficiency cost parameter w allowed to vary as indicated.
The rest of the parameters are baseline values (Table 2) except that δ = 7, dR = 0.45 and dS = 0.45, with values for Xswitch, Δu, and w: A. & B. Δu ranging from 0 to 0.5 in steps of 0.001, v = 0.5; C. & D. Xswitch ranging from 0 to 32000, in steps of 50; E. & F. w ranging from 0 to 5 in steps of 0.01 (cf. individual trajectories used to obtain the mean and standard deviation for selected values of Δu and Xswitch in Fig. 3, but averaged here over 1000 years to minimize the impact of the initial conditions).
