Dredge MuMIn: when using a dredge on a GLMM, does the null model include random effects?

I have a global model using a GLMM with 5 fixed effects with interactions, as well as two random effects. x ~ a*b + a*c + a*d + a*e + (1|f) + (1|g) I am using an information theoretic approach and have used the dredge() function in MuMIn on this…
