Comparison of life history traits of the tuatara with those predicted from our allometries for a similar‐sized crocodile, turtle, or squamate
| Crocodile | Turtle | Squamate | |
|---|---|---|---|
| Clutch size | 0.46 | 0.10 | 0.18 |
| Egg weight | 0.62 | 0.40 | 0.29 |
| Size at maturity | 0.57 | 0.15 | 0.22 |
| Age at female maturity | 0.51 | 0.32 | 0.78 |
| Incubation time | 0.58 | 0.79 | 0.69 |
| Max. longevity | 0.34 | 0.49 | 0.74 |
| Birthweight | –a | 0.32 | 0.44 |
| Number of clutches per year | –a | 0.85 | 0.62 |
Shown are the residual values (the difference between the logarithmized value and the value predicted by the respective regression line from the tuatara's body mass) for eight life history traits.
Residual value in bold = smallest difference between predicted value and the tuatara's value.
