Fig. 4.
Variation partitioning of changes in the frequency of infected cells (FIC) and viral production (VP). The figure shows the percentage of the variation in FIC (a) and VP (b) relative to controls and throughout the entire incubation period (32 h and 72 h analyzed together) that is explained by in situ biological parameters (prokaryotic leucine incorporation, prokaryotic and viral abundance) corrected and uncorrected for the influence of water masses, water-mass defining parameters (temperature, salinity) corrected and uncorrected for biological parameters, water-mass correlated biological parameters, and that remains unexplained in the form of a Venn diagram. Data from single source transplantation and mixing treatments were analyzed together. Statistically significant values are in bold, insignificant values are in gray, and values that cannot be tested for statistical significance are in italics.
