Growth rates (growth constants of logistic equations) fitted to growth curves of tyrannosaurs (Erickson et al. 2004), wandering albatross (Starck & Ricklefs 1998) and several large mammals (Zullinger et al. 1984).

Logistic growth rate predicted by the regression equation for the Gompertz growth rate for a large sample of mammals: logKG (days−1)=−0.901 to 0.302 log asymptote (kg) (Zullinger et al. 1984).
