Relative abundance of each bacterial family collected from the guts of beetles (a) from each habitat and b with each food habit. Sampling depth was set to 1300 to remove samples with low sequence reads. OTUs that could not be classified into orders are summarized as “Unclassified.” Names of classified families with total abundances > 5% are shown with order names in parentheses. Other families are summarized as “Others.”
