  1. Length ratio: because there was a significant interaction between vertebra position (i.e. number in tail) and curvature (see Figure 4), we further compared length ratios among individual vertebrae for curved and non-curved individuals. Width ratio: because there was a significant interaction between sex and vertebra position (see Figure 4), we further investigated the width ratio among individual vertebrae for males and females. Comparisons conducted with one-way ANOVA, (significance threshold: α = 0.05). Significant results are shown in bold. Mean values for each vertebra is shown with the standard error in parenthesises. Standard error was calculated using a pooled estimate of error variance.
