Black symbols with negative error bars represent values from caimans that were first feed then fasted, white symbols with positive error bars are values from caimans fasted for 3 months then feed a single meal. Values are least square means ± s.e.m. derived from RM ANCOVA; for raw data see Table 1. Arrows indicate feeding events for each experimental group.
