Taxonomic composition of the domain Eukaryota based on predicted gene annotations in assembled metagenomes. Annotations were based on ≥30% identity over ≥70% of the alignment length, with three exceptions: genera Micromonas, Oikopleura, and Theileria. For these genera, predicted peptides were annotated at ≥90% identity (over ≥70% of the alignment length), and their numbers were subtracted from the numbers for the corresponding phyla (Chlorophyta, Chordata, and Apicomplexa for Micromonas, Oikopleura, and Theileria, respectively). The metagenome names provide information on sampling locations and water salinity (PSU; OW‐33, ocean water; PL‐25 and PL‐15, plume; ES‐5, estuarine; RW‐0, freshwater)
