The patterns of co-occurrence variation are explained by the low dependence of bark beetles (Coleoptera: Scolytinae and Platypodinae) on hosts along altitude gradients

Table 1 Results of Beta regression in Generalized linear models testing for the relationships between both beetles and trees composition variation at regional and local spatial scales with sampling elevation gradient respectively
