Multivariate allometry coefficients (AC), theirs standard errors (SE AC) and 95% confidence limits (L1 and L2) for both genera based on the first principal component extracted from each genus within-group V/CV matrix. PC1 vectors were normalized and each coefficient divided by (1/39)1/2 to obtain the AC. Standard deviation estimates obtained from bootstrap analysis. Allometric coefficients with L1 higher that one (isometry) were considered to be positively allometric with general size (shown in bold and underlined) and conversely, AC with L2 lower that one were considered to be negatively allometric (bold and italic) with size. ACs with confidence limits encompassing 1.0 were considered to be isometric with size (normal font). The last column show the first principal component extracted from the whole sample (Cebus+Saimiri) and used in the MASS transformation.
