Table 5. Generalised linear mixed model results of ant mire specialists, generalists and forest species. Model estimates, standard errors (SE) and p-values of terms retained in the models are given. Treatment, Sphagnum cover, hummock cover and number of trees (> 3 m) were a priori chosen as important environmental variables for the ant occurrences and were retained in all final models. Other variables were subject to model selection and their values are only given when they remained in the final model. Statistically significant p-values (< 0.05) are in bold. The intercept represents prediction in the pristine mire treatment. Est. = Estimate. * = mire specialist species, ** = generalist species, *** = forest species, all according to our a priori evaluations. | ||||||||||||
