Effect of varying the diet breadth σ on the fitted linear regressions (circles – density-mass allometry (1); crosses – variance-mass allometry (2); squares – Taylor's law (3)): (a) exponents a₁, b₁, and c₁; (b) intercepts a₀, b₀, and c₀; (c) r². All other parameter values were as in Table 1. Dashed vertical line shows the value of σ = 1.5 corresponding to the results shown in Figure 1.
