Table 3. Distribution of facial integration magnitudes under an allometric PLS, as measured by the RV coefficient.

Species/sex	Face (oral-zygomatic)	Face (max. modularity)	Cranium (face-base)	Cranium (max. modularity)
C. albifrons	0.39	0.22	0.40	0.26
C. olivaceus	0.38	0.23	0.44	0.27
C. apella s.s.	0.59	0.40	0.64	0.42
C. libidinosus	0.57	0.33	0.62	0.36
C. nigritus	0.53	0.31	0.53	0.35

All RV coefficients are significant at p<0.0001.
