Thank you all for the answers. I'll be careful with this kind of models
till I learn how they work...
By the way, I have realized that, comparing a Poisson model with a
quasi-Poisson model, the estimated SE of the coefficients in the
quasi-Poisson model are the SE of the Poisson model

Hello,
I am trying to simplify backwards a mixed effects model, using lmer
function from lme4 package. As my data are species numbers and there
exists overdisperison, I think appropriate to use glmer function with
error family quasipoisson. I compare one model with its
