Effect of Cumulative Exposure (CE) and Female order (F) on variation of SF volume.
| No. | Fixed effects | k | Log-likelihood | AIC c | ΔAICc | Weight |
|---|---|---|---|---|---|---|
| 1 | CE | 4 | −75.37 | 159.58 | 0.00 | 0.38 |
| 2 | CE + F | 5 | −74.47 | 160.21 | 0.63 | 0.27 |
| 3 | CE + F + CE × F | 6 | −73.50 | 160.83 | 1.25 | 0.20 |
| 4 | Null | 3 | −77.81 | 162.12 | 2.54 | 0.11 |
| 5 | F | 4 | −77.55 | 163.94 | 4.36 | 0.04 |
All models include a random effect for male identity. Fixed effects: CE = Cumulative Exposure, F = Female order. Models are ranked by increasing AICc values. For each model we show: fixed effects, number of estimated parameters (k), log-likelihood, AICc, ΔAICc (difference between given model and model 1) and the Akaike weight. The most parsimonious models are above the dashed line, and the best minimal model is in bold. Models included 53 observations from 17 males.
