Ammonium and Sulfate Assimilation Is Widespread in Benthic Foraminifera

Frontiers in Marine Science, 2022
Nitrogen and sulfur are key elements in the biogeochemical cycles of marine ecosystems to which benthic foraminifera contribute significantly. Yet, cell-specific assimilation of ammonium, nitrate and sulfate by these protists is poorly characterized and ...

A dataset on trophic modes of aquatic protists [PDF]

Biodiversity Data Journal, 2020
An important functional trait of organisms is their trophic mode. It determines their position within food webs, as well as their function within an ecosystem.

Microscopic marine invertebrates are reservoirs for cryptic and diverse protists and fungi

Microbiome, 2022
Background Microbial symbioses in marine invertebrates are commonplace. However, characterizations of invertebrate microbiomes are vastly outnumbered by those of vertebrates.

Ectosymbiotic bacteria at the origin of magnetoreception in a marine protist [PDF]

Nature Microbiology, 2019
Mutualistic symbioses are often a source of evolutionary innovation and drivers of biological diversification1. Widely distributed in the microbial world, particularly in anoxic settings2,3, they often rely on metabolic exchanges and syntrophy2,4. Here, we report a mutualistic symbiosis observed in marine anoxic sediments between excavate protists ...

Biogeographical Distribution and Community Assembly of Active Protistan Assemblages along an Estuary to a Basin Transect of the Northern South China Sea

Microorganisms, 2021
Marine protists are essential for globally critical biological processes, including the biogeochemical cycles of matter and energy. However, compared with their prokaryotic counterpart, it remains largely unclear how environmental factors determine the ...

Heterotrophic Foraminifera Capable of Inorganic Nitrogen Assimilation

Frontiers in Microbiology, 2020
Nitrogen availability often limits biological productivity in marine systems, where inorganic nitrogen, such as ammonium is assimilated into the food web by bacteria and photoautotrophic eukaryotes.

Multiple integrated metabolic strategies allow foraminiferan protists to thrive in anoxic marine sediments

Science Advances, 2021
Mitochondria-bearing microeukaryotes produce energy through anaerobic pathways to succeed in the face of ocean deoxygenation. Oceanic deoxygenation is increasingly affecting marine ecosystems; many taxa will be severely challenged, yet certain nominally ...

Erratum to: Optimising sampling frequency for monitoring heterotrophic protists in a marine ecosystem

ICES Journal of Marine Science, 2021
Heterotrophic protists are essential components of the marine ecosystem, yet they are often excluded from monitoring programmes. With limited resources, monitoring strategies need to be optimised considering both scientific knowledge and available ...

Mixotrophic plankton foraging behaviour linked to carbon export

Nature Communications, 2022
Marine mixotrophic protists that use both heterotrophic and phototrophic metabolisms may impact the carbon cycle in unexpected ways. A recently characterized mixotroph can craft three-dimensional mucilage feeding structures that trap nutrient-rich ...
