count data (species richness and abundances).
My data are spiders and ground beetles trapped in pitfalls in different
locations and habitats and in different periods during a season.

Grazie Achaz,
the tutorial you linked gives useful hints.
I will consider the bayesian route but at the moment I am looking for a
reference that legitimates me to keep the poisson error distribution with
glmer and catch the overdispersion in the few models where my actual random
effects looks like
