The allometric relationship between fat body mass (Mfb) and body mass (Mb) of young tegu lizards (Tupinambis merianae) at distinct activity states during the first annual cycle. Autumn activity corresponds to late autumn, and arousal to unfed, rehydrated animals in Table 1. Linear regressions were performed on log-transformed Mfb (g) and Mb (g) as described by log10 Mfb=a+b log10Mb.
