TABLE 2.

Growth parameters specified by the von Bertalanffy model for each juvenile vervet category group in the between-population comparison, where a is the asymptotic weight, maximum growth rate is given in grams/day (estimated by multiplying the growth rate constant, k, by estimated weight at the inflexion point of the curve) and t0 is the age (in days) at inflexion in the growth curve (the point at which the acceleration in growth changes from positive to negative)
