Results of the best GLMMs to test whether the percentage feeding time (arcsin transformed) was affected by sward height and competitors based on AIC.

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 △AICdf; logLik, △AIC = AIC(i)—AIC(min); ωi = Akaike weights).
