Figure 2. Distribution of reproductive power (W) across mammal and bird groups with body size frequency curves as predicted by the BMT model. (A) Distribution of reproductive power across mammals. (B) Distribution of reproductive power across birds. Solid lines represent BMT models derived from the universal scaling exponents of b0 = 0.75 and b1 = −0.25, whereas dashed lines indicate BMT models derived from the alternate scaling exponents of b0 = 0.67 and b1 = -0.33.
