Carbon and nitrogen content to biovolume relationships for marine protist of the Rhizaria lineage (Radiolaria and Phaeodaria) [PDF]
Limnology and Oceanography, 2021 Rhizaria are large protistan cells that have been shown to be a major component of the planktic community in the oceans and contribute significantly to major biogeochemical cycles such as carbon or silicon.

Reducing long-branch effects in multi-protein data uncovers a close relationship between Alveolata and Rhizaria [PDF]
Molecular Phylogenetics and Evolution, 2016 Rhizaria is a major eukaryotic group of tremendous diversity, including amoebae with spectacular skele- tons or tests (Radiolaria and Foraminifera), plasmodial parasites (Plasmodiophorida) and secondary endosymbionts (Chlorarachniophyta).

Deep relationships of Rhizaria revealed by phylogenomics: A farewell to Haeckel’s Radiolaria
Molecular Phylogenetics and Evolution, 2013Rhizaria is one of the six supergroups of eukaryotes, which comprise the majority of amoeboid and skeleton-building protists living in freshwater and marine ecosystems. There is an overall lack of molecular data for the group and therefore the deep phylogeny of rhizarians is unresolved.

Molecular Phylogeny of the Widely Distributed Marine Protists, Phaeodaria (Rhizaria, Cercozoa) [PDF]
Protist, 2015 Phaeodarians are a group of widely distributed marine cercozoans. These plankton organisms can exhibit a large biomass in the environment and are supposed to play an important role in marine ecosystems and in material cycles in the ocean. Accurate knowledge of phaeodarian classification is thus necessary to better understand marine biology, however ...

Phylogenetic Revision of the Order Entactinaria—Paleozoic Relict Radiolaria (Rhizaria, SAR)
Protist, 2020Entactinaria, an order of Radiolaria, are defined by a specific skeletal structure called "initial spicular system (ISS)". The oldest entactinarians appeared in the Ordovician period, and the extant species are thought to have survived until today.

Copepods and mixotrophic Rhizaria dominate zooplankton abundances in the oligotrophic Indian Ocean [PDF]
Deep-Sea Research Part II: Topical Studies in Oceanography, 2022 The large, tropical oligotrophic gyres of the world's oceans are understood to be relatively unproductive, with low phytoplankton and zooplankton biomass, and inefficient food webs, although data are scarce. Here we investigate changes in the zooplankton

First record of a Xenophyophore (Rhizaria: Foraminifera) on the Chilean margin
Zootaxa, 2018Xenophyophores are a group of large foraminifera, confined to deep-sea habitats below ~500 m, whose often fragile agglutinated tests may attain sizes up to 10–15 cm or more; their agglutinated tests incorporate a variety of foreign particles (termed ‘xenophyae’), including mineral particles, foraminiferan and radiolarian tests, diatom frustules and ...

Rhizaria in the oligotrophic ocean exhibit clear temporal and vertical variability
Deep-Sea Research Part I: Oceanographic Research PapersRecently studies have shown that Rhizaria, a super-group of marine protists, have a large role in pelagic ecosystems. They are unique in that they construct mineral tests out of silica, calcium carbonate, or strontium sulfate. As a consequence, Rhizaria can have large impacts on the oceans cycling of carbon and other elements.
