 Time (weeks)

Figure 2-2. Body mass (a) and straight carapace length (b) (mean + standard error) at the
 midpoint of each week. 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.
