a
Abundances are annual means of the proportions of DAPI-stained cells (taken as 100%) either targeted by the universal probe EUK1209R or identified as heterotrophic flagellates via primuline staining.
b
Results are annual means of the abundances (relative to that of the total small eukaryotes targeted by EUK1209R, taken as 100%) of the eight eukaryotic groups targeted by TSA-FISH using specific oligonucleotide probes.
