Fig. 5. Geometric standard deviations s_g=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. s_g is a measure of relative variation and is approximately 1+CV. Note the typically higher variation in batch B₁.
