Relationship of trophic state, heterogeneity, and their combination with abundance, richness, dissimilarity of bacterial communities among lake habitats (“Dissimilarity”), and the proportional abundance of common taxa. ‘n’ = sample size and ‘k’ = number of parameters in each model. ‘wi’ refers to the AICc weight calculated for each model and the weights for the individual terms ‘T’ and ‘H’ across all models.
