WebZuur et al., and Faraway (from @janhove's comment above) are right; using likelihood-based methods (including AIC) to compare two models with different fixed effects that are fitted by REML will generally lead to nonsense. Faraway (2006) Extending the linear … WebREML versus ML estimator. When estimator = "ML", which is the default for linear mixed models (unless they share the same fixed effects), values from information criteria (AIC, AICc) are based on the ML-estimator, while the default behaviour of AIC() may be different (in particular for linear mixed models from lme4, which sets REML = TRUE).This default …
