Legend of Table 5. Partial output of two-factor ANOVA, showing only the statistical significance associated with each factor (sensilla, parks) after ANOVA performed on first (PC1) and second (PC2) principal components of shape, as derived from either outlines or landmarks. Between brackets, the contribution of the PC to the total variation. NS = not significant.
