Measure	Correlation coefficients with PCs^†
Measure	PCI	PC2
Adult mass	−0.03	0.98
Birth mass^‡	−0.10	0.00
Litter size	0.51	−0.64
Conceptus mass^‡	0.99	0.01

Note: Values in boldface indicated strongest correlates with PC scores.

^†

For principal components 1 and 2 the eigenvalue, percentage of variance explained, and cumulative percentage explained were 2.87 and 2.24, 41.1% and 32.1%, and 41.1% and 73.1%, respectively.

^‡

Linear regression indicated significant effect of body mass; residuals used in PC A.
