Connected temporal dynamics of predicted virus-host pairs. A Temporal dynamics of active DNA phages exhibiting a significant seasonal pattern in activity (n = 144). The significance of changes in abundance between months was tested with a multiple group statistic test (ANOVA), a post hoc test (Tukey–Kramer) to identify which pairs of months differ from each other and a multiple test correction (Storey’s FDR) to control false discovery rate, using STAMP. The seasonal dynamic of each active DNA vOTU exhibiting significant changes in abundance between months was plotted using the mean of metatranscriptomic RPKM transformed in z-score. Each vOTU was associated to a specific season based on its peak of activity (colored lines). vOTU dynamics are grouped by panel depending on the “ecology strategy” of their assigned host (see the “Methods” sections). Each host was associated to an “ecological strategy” depending on the month (or season) a given host was supposed to be growing [6], represented by colored boxes in each panel. Finally, all active DNA vOTUs without an assigned host or host without a clear ecological strategy were plotted in the last panel. B Distribution of predicted host taxa for active DNA vOTUs with significant seasonal activity pattern (see above), grouped by host growth strategy as in panel A
