 Time (weeks)

Figure 2-3. Condition index (mean + standard error) in each week calculated as BMICL3, where
 BM = body mass (g) and CL = carapace length (cm). Different letters indicate values
 that are significantly different within weeks (analysis of variance, Tukey's HSD post
 hoc test, p < 0.05). The arrow indicates the time at which turtles in the R-AL group
 were switched from a restricted diet to an ad libitum diet. Sample sizes and
 abbreviations are the same as in Figure 2-1.
