Table S1. Source and identification of studies used for comparative meta-analyses in Fig. 1a, b and Additional file 1 Figure S2. Table S2. Comparison of selected alpha diversity indexes for various 16S datasets from different habitats (N = number of samples in study). All datasets were subsampled to 2000 sequences prior to analyses, more information on the data used can be found in Additional file 1: Table S1. Table S3. Comparison of the abundance of total bacteria, methanotrophs, methanogens, fungi, and fungal to bacterial ratio (F/B) in the trap and periphyton of Utricularia species (data are averages from U. australis and U. vulgaris samples). Quantification of bacteria, fungi, methanotrophs and methanogens was done using the 16SrDNA, 18SrDNA, pmoA, and mcrA gene copy numbers, respectively. Quantity was normalized to total amount of DNA. Table S4. The 5 most important potential keystone taxa in the Utricularia-associated microbiomes, based on network analyses. Figure S1. Experimental Utricularia vulgaris shoot on a Petri dish. Segmented leaves bearing traps and the growth tip are visible. Figure S2. Compositional overlap in Utricularia-associated prokaryotic microbiomes at the genus level. (a) Comparison between U. australis and U. vulgaris microbiomes and (b) between the U. australis and U. vulgaris periphyton and trap environments. Figure S3. Co-occurrence network for the prokaryotic community in the periphyton of Utricularia vulgaris, constructed from QIIME 16S data. Figure S4. Co-occurrence network for the prokaryotic community in the trap fluid of Utricularia vulgaris, constructed from QIIME 16S data. Figure S5. Tetrahymena utriculariae under the epifluorescence microscope. Zoochlorellae are visible in purple, the nucleus is stained blue, and fluorescently labeled bacteria in food vacuoles show green fluorescence. (DOCX 5108 kb
