TABLE 4.
Principal component loadings based on life history traits measured on three lizard populations across the latitudinal thermal gradient.
| Variable | Loadings | |
|---|---|---|
| PC 1 | PC 2 | |
| Weekly growth rate | −0.20 | 0.95 |
| Snout–vent length | 0.90 | −0.02 |
| Postoviposition mass | 0.96 | −0.11 |
| Eggs per clutch | 0.97 | −0.08 |
| Average egg mass | 0.29 | 0.69 |
| Clutch mass | 0.87 | 0.19 |
| Eigenvalue | 3.84 | 1.14 |
| Rotated Eigenvalue | 3.75 | 1.94 |
| % of variance | 64.0 | 19.0 |
| Cumulative % variance | 64.0 | 83.0 |
