from the deep seafloor7 suggests that deep-sea microbial food webs might function in a similar way as those in surface waters. Barotolerant or barophilic nanoprotists (<20µm) may live at high

Jul 13, 2023 · Establishing trophic linkages allows us to identify which pathways supply energy to deep-sea food webs. In this study, we show that the base of the mesopelagic food web at Sta. P is composed primarily of < 6 μm particles and that active transport and large particles may represent secondary sources of organic matter. Protistan heterotrophs are ...
Apr 17, 2018 · Before the advent of robotic exploration technology, much of what scientists gleaned about food webs was gathered from animals hauled to the surface in nets — or discovered in a predator’s guts. One problem with that approach, Anela says, is that squishy animals like jellyfish and other gelata, while among the most prevalent life forms in ...
Mar 5, 2024 · DEEP-SEA SEDIMENT-DWELLING PROTISTS. Although it is generally accepted that almost all phylogenetic groups of flagellated protists can be found in the deep-sea floor, there are only a few dozen confirmed observations of living specimens from these habitats, either from samples or isolated cultures (see Figure 1). Unlike many foraminiferans ...
Microbial eukaryotes (or protists) in marine ecosystems are a link between primary producers and all higher trophic levels, and the rate at which heterotrophic protistan grazers consume microbial prey is a key mechanism for carbon transport and recycling in microbial food webs. At deep-sea hydrothermal vents, chemosynthetic bacteria
Jul 20, 2021 · Protists serve as a link between primary producers and higher trophic levels, and their grazing is a key mechanism for carbon transport and recycling in microbial food webs, the paper states. The research found that protists consume 28-62% of the daily stock of bacteria and archaea biomass within discharging hydrothermal vent fluids from the ...
