Table 4: Missing and under-represented groups and severely amalgamted nodes.
Missing groups Notes Underrepresented groups Notes Severely aggregated nodes Notes
Bird Ectoparasites Bird ectoparasites such as lice and mites are definitely present in the system but were not sampled. Ectoparasites of Fishes Fish ectoparasites and micropredators are difficult to sample and are thus likely undersampled. Bacteria Free-living and symbiotic bacteria were not sampled in this web. 
Protists Symbiotic and non-photosynthetic free-living protists are not included in the web. Epipelic Flora This node, likely the most speciose aggregated assemblage, comprises the microphytobenthos, which is mostly diatoms.
Plant Ectoparasites These include herbivorous insects that could be deemed parasitic by our consumer strategy definitions. Macroalgae This assemblage contains all multicellular algae
Saprophytic Fungi Fungal communities, an important component of the decomposers were not sampled. Meiofauna This common name group includes Phyla like free-living nematodes, gnathostimulids and kinorhynchs.
Viruses Viruses and phages on all nodes were severely undersampled. Phytoplankton This node comprises the autotrophic component of the plankton community (e.g. diatoms, dinoflagellates and cyanobacteria).
Zooplankton This assemblage includes all holoplanktonic and meroplanktonic organisms.
