First value is without removing allometry and second value is after regressing out allometry. Dimensions represent SW axes, correlations (r) represent the strength of integration between blocks, P-value shows the statistical significance (permutation test) of the correlation coefficient (r), and the last column presents the percentage of covariance explained by each dimension. Numbers in bold signify statistical significance at P ≤ 0.10.
