The plot shows the predicted body mass by range size (pMCMC99.6 >95). Light transparent lines indicate the posterior regression lines linking body mass with range size. The dark line indicates the mean regression line obtained from the inset model formula. Grey-filled circles illustrate range sizes (n = 120 species).
