Experimental Evidence Shows the Importance of Behavioural Plasticity and Body Size under Competition in Waterfowl
Table 4
Results of the best GLMMs to test whether the percentage vigilant time (arcsin transformed) was affected by sward height and competitors.
In the model sward height, competitor and their interaction term were included as fixed factors, whereas session, enclosure number, and individual were always included as random factors in all models. NS indicates that the parameter was not included in the model. All models with △AIC<2, and the next best model are reported (AIC = Akaike Information Criterion. df; logLik, △AIC = AIC(i)—AIC(min); ωi = Akaike weights).
