Temporal and seasonal abundance of viruses in Ace Lake. Stacked bar graph depicting the relative abundance of viruses. The data on the x-axis are sampling date and depth (U1, upper 1; U2, upper 2; U3, upper 3; I, interface; L1, lower 1; L2, lower 2; L3, lower 3). Each depth contains three bars which represent from left to right, 20–3, 3–0.8, and 0.8–0.1 μm filter fractions (see Additional file 1: Table S1 for specific information about sampled depths). The sampling periods represent summer (Dec. 2006, Dec. 2013, Feb. 2014, Dec. 2014, and Jan. 2015; only Upper 1 was sampled in Dec. 2013, Feb. 2014, and on 8th and 27th Jan. 2015), winter (Jul. 2014 and Aug. 2014), and spring (Nov. 2008, Nov. 2013, and Oct. 2014). The data on the y-axis represent the sum of the relative abundances (%) of the virus OTUs, classified as dsDNA (orange bar) or Other viruses (blue bar). The Other viruses are unclassified viruses identified in IMG plus Unassigned contigs that were confidently predicted by VirSorter as viruses (category 1 and 2) and prophages (category 4 and 5); note that the metagenome data do not represent ssDNA or RNA viruses
