Time (weeks)
Figure 2-4. Specific growth rate (mean + standard error) for body mass (BM, a) and straight
carapace length (CL, b) during each week calculated as 100*(ln[sizet +]-ln[sizet])/7
where size = BM (a) or CL (b) and t = time (weeks). 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.
