The need to scale for differences in body size and mass: an explanation of Kleiber's 0.75 mass exponent

When modeling intraspecific relationships between selected measurements (Y) for differences in body mass (m) using the allometric equation Y = amb (where a is a constant and b is the exponent parameter), various studies have reported exponents greater than the anticipated 2/3, often closer to the exponent 0.75 identified by Kleiber. A possible explanation for these exponents is proposed based on the findings of Alexander et al. (J. Zool. Lond....
