Models within 2 AIC points of the top model are given in bold. Key to symbols: M, Mean body mass for species pair; D, Mass difference of species pair, expressed as a percentage of the heavier species' mass; G, Mean generation length for species pair; RL, Model relative likelihood; Wa, Model Akaike weight.
