a Taxa abundances in the combined dataset based on EMIRGE-reconstructed 16S and 18S rRNA gene sequences. Bac Bacteria, Euk Eukaryota. b Microscopy images of Microcoleus, eukaryotic phototrophs (diatoms and Cosmarium), and biofilm grazers (chironomid larvae and rotifers). c Unrooted maximum likelihood tree of all 81 prokaryotic MAGs. Black lines indicate references from GTDB, and other tip colors indicate phyla-level clades. d Bar chart showing temporal changes in the relative genome coverage of the top 20 MAGs clustered by order level.
