Mixed linear model analysis of the effects of age and shell morphology (size PC1, or shape PC2 and PC3) on female reproduction
Clutch size | Total clutch mass | Mean egg mass | ||||

Factor | χ2-value | P-value | χ2-value | P-value | χ2-value | P-value |
PC1 | 1.97 | 0.16 | 4.76 | 0.03 | 12.8 | <0.001 |
PC2 | 13.1 | <0.001 | 64.3 | <0.001 | 110.2 | <0.001 |

Note: Data are from a subset of ‘primiparous females’ with nearly contiguous nesting records (n = 38 individuals). Models include individual turtle ID as a random effect.
