Permutational analyses of swimming performance and metabolic scope for males and females in Experiment 2.
| d.f. | Ucrit | Scope | |
|---|---|---|---|
| Gran | 1 | <0.001 | 0.0080 |
| Sex | 1 | <0.001 | 0.062 |
| Test | 1(2) | <0.001 | <0.001 |
| Gran*Sex | 1 | 0.12 | 0.12 |
| Gran*Test | 1 | 0.97 | 0.034 |
| Sex*Test | 1 | 0.58 | 0.94 |
| Gran*Sex*Test | 1 | 0.019 | 0.82 |
| Residual | 114 |
Permutational probabilities are shown for analyses of critical sustained swimming speed (Ucrit) and metabolic scope (Scope). The fixed factors were grandparental temperature (Gran; 23 °C and 29 °C), sex (male and female), and test temperature (Test; 18, 26, 32, and 36 °C). Degrees of freedom (d.f.) are shown; note that Test for Ucrit has one extra d.f. because we used a quadratic term in the model. Please see main text for details of analyses.
