Phylogenetic tree of 18S rRNA gene sequences extracted from Lake Mendota metagenomes over the 20-year time series. Colored, filled circular points on the tree indicate novel sequences extracted from the Mendota metagenomes, while smaller black circles denote a representative set of previously published sequences. The outer heatmap represents the mean Z-score of extracted sequence during each of the seasons of the year, and bars show the number of samples the 18S rRNA gene was found in
