Abbreviations: Conc., concentration; DAPI, 4,6-diamidino-2-phenylindole; DOCp, phytoplankton-derived dissolved organic carbon; IS, interaction strength; MAR, microautoradiography.
Coefficient use two different IS metrics (MAR+g/DAPI counts and MAR+g/MAR+Eub, see text for details); Roseobacter and SAR11 are both subgroups of Alphaproteobacteria.
Note that these are not true replicates.
