Average Abundances of a Broader List of Plankton Groups across Latitude, Related to Figures 1 and 2

For 18S rDNA metabarcodes (relative abundances), imaging from net catches and flow cytometry (absolute abundances). Numbers refer to the filter mesh size (μm). H: non-photosynthetic/heterotrophic, P: photosynthetic/mixotrophic. See Figures 1 and S1 for further sampling details. The three viral groups are not represented here due to absence of comparable abundance data. Note that the differences between protocols relate, among other things, to resolution (e.g., potential photohosts from the nets are classified as Protists (H)), marker gene copy number (e.g., high in photohosts), lack of detection (many small copepods are lost when sampling with nets), or water column sampling differences (surface [SRF] or deep chlorophyll maximum [DCM] versus integrative [INT] for molecular/cytometry versus net catches, respectively).
