Insignificant covariates are denoted with “-”. *, p < 0.05; **, p < 0.01; ***, p < 0.001, NS, not significant; NA, no estimate. Catch nights were tested together, and the significance is shown at each first catch night. The p-values for the main effects includes the removal of both main effects and any interactions with this. No significances are given for the effect of catch nights, which were included as a systematic effect in all models.
