[R-sig-ME] Effect size for lmer and glmer

Dear All,

I am trying to calculate the effect size from lmer and glmer models that looks like that:

q0100 <- lmer(q0 ~ Management + Width + NonCrop100 + 
                Management * NonCrop100 + (1 | Plot.No), Alpha)

Pres100<-glmer(Present ~ Management + 
                 Management : status + 
                 Management : NonCrop100 +
                 status + 
                 NonCrop100 : status + 
                 NonCrop100 +
                 Management : Dispersal + 
                 Dispersal +
                 NonCrop100 : Dispersal +
               family=binomial, data=Presence)

Can you help me to calculate the effect size of the fixed variables and the interactions from the above mentioned models. I do have many other models that I like to compare all of them according to the effect size of each of which on the diversity measures, abundance and p/a data.
