Summary of growth models used to examine longitudinal variation in growth parameters k and L∞.

f1 and f2 are functions of the growth parameters where α1 and α2 describe the relationship between L∞ and l, and β1 and β2 describe the relationship between k and l. K is the number of estimated model parameters (plus one for variance). AICc is the small-sample bias-corrected form of Akaike’s information criterion, Δi is the Akaike difference, and wi is the Akaike weight.
