Fig. 5. Geometric standard deviations sg=exp{sd[log(x)]} of
corrugated setae (A), aesthetascs (B) and carapace length (C) with 95%
confidence limits. Data are split according to batches (A, B, B1,
B3) and juvenile stages (J2, J3, J4, J5, J6). The normality
approximation in s.d. confidence limits does not hold for those aesthetasc
data sets (in B) that showed no variation, and therefore no confidence limits
are given in these cases. The dots correspond to the estimated standard
deviation. sg is a measure of relative variation and is
approximately 1+CV. Note the typically higher variation in batch
B1.
