Figure 1

Scaling relationship between cube root body mass and tibia length in mammals. Ordinary least squares regression of log tibia length (mm) on log cube root body mass (g0.33) across 227 species of terrestrial mammal, from the ~20 g red-backed vole (Myodes gapperi) to the 5.4 ton African elephant (Loxodonta africana). There is a negative allometric relationship between body mass and tibia length; species that deviate the most from the expected relationship tend to be specialized for bounding, cursoriality and/or bipedal locomotion (positive residuals, a sample of better known species with large positive residuals is indicated by stars), or for graviportal locomotion (negative residuals). Data from [5],[13]-[16], Campbell Rolian (personal data) and Kevin Middleton (personal data).
