Table 3. Principal Component reductions of body shape.

Log-shape ratios were used to perform a principal components analysis, after centering and scaling the data. Eigenvectors are reported here, together with the proportion of variance assigned to each component. The first three principal components were used in phylomorphospace visualizations.
