Abbreviations: DAPI, 4,6-diamidino-2-phenylindole; IS, interaction strength; MAR, microautoradiography.
Specialization indices use two different IS metrics (MAR+g/DAPI counts and MAR+g/MAR+Eub, see text for details), calculated for each bacterial phylogenetic group (d') and for the entire interaction networks (H2') as proposed by Blüthgen et al. (2007).
‘Altogether' refers to the results merging all treatments in a single network.
