Fig. 2. The relationship between (A) effective limb length (LE) and (B) body mass and the cost of transport (COT) for all 28 species. (C) Path analysis indicating the independent effects of LE and body mass on the mass-specific cost of transport. Results of Analysis group 1 species are shown; similar results were obtained for Analysis groups 2 and 3. Arrow thickness is proportional to path coefficient. N=15 species, d.f.=12 for all comparisons.
