I'm trying to make a glmm to identify the relationship between insect
species richness with fragment size, isolation and time (different years).
I already tried to analyse it using poisson distribution error, but I
always face with the following warning:
*glm.fit: fitted probabilities numerically 0 or 1 occurred *

This is probably hapenning because my dataset has a lot of zeros. So, what
error distribution should I use?
