Values along the diagonal indicate shape difference between sexes at each age level; above diagonal are 95% confidence intervals for pairwise comparisons of sexual dimorphism among age levels. The pairwise comparisons were performed by subtracting sexual dimorphism at the younger age from the difference at the older age.
