Table 2 Summaries of the principal component (PC) analyses, Procrustes ANOVA(allometry) analyses, two-block partial least squares (2BPLS) analyses, and correlation statistics between PLS 1 scores with the species’ PC1 scores and centroid sizes. n, number of specimens used in the analyses; R2, coefficient of determination of linear models; t, t-statistic of correlation test; p: p-value, CW common wombat; NHNW northern hairy-nosed wombat; SHNW southern hairy-nosed wombat

From: Individual variation of the masticatory system dominates 3D skull shape in the herbivory-adapted marsupial wombats
