Phylogenomics supports the monophyly of the Cercozoa.

Molecular Phylogenetics and Evolution, 2019
The phylum Cercozoa consists of a diverse assemblage of amoeboid and flagellated protists that forms a major component of the supergroup, Rhizaria. However, despite its size and ubiquity, the phylogeny of the Cercozoa remains unclear as morphological ...

Cell Structure of Predatory Flagellate Metromonas grandis Larsen et Patterson (Cercozoa)

Inland Water Biology, 2020
The ultrathin structure of carnivorous flagellate Metromonas grandis Larsen et Patterson has been investigated. The predator captures the whole cell of the prey (bodonids or chrysomonads). Cytostome as a cell pocket has not been found. The cell, besides the flagella and small parts of the folds, is surrounded by a fibrous layer 0.05–0.12 µm in ...

Shell Colour in Cercozoa; a Simple Trait to Distinguish Thecofilosea from Imbricatea?

Protist, 2020
Rigid and persistent shells of microeukaryotes are widely used as bioindicators in ecological and paleontological studies. Drawing conclusions on ecological or evolutionary patterns depends strongly on the right taxonomic assignment of the observed ...

Grazing of leaf‐associated Cercomonads (Protists: Rhizaria Cercozoa) structures bacterial community composition and function

Environmental Microbiology, 2017
Summary Preferential food selection in protists is well documented, but we still lack basic understanding on how protist predation modifies the taxonomic and functional composition of bacterial communities. We conducted feeding trials using leaf‐associated cercomonad Cercozoa by incubating them on a standardized, diverse bacterial ...

Food Choice Experiments Indicate Selective Fungivorous Predation in Fisculla terrestris (Thecofilosea, Cercozoa)

Journal of Eukaryotic Microbiology, 2018
Thecofilosea is a class in Cercozoa comprising mainly freshwater inhabiting algivores. Since direct observation of amoeboid protists in soil is not possible, the prey spectra of their terrestrial relatives remain obscure.

Phylogeny and Redescription of the Testate Amoeba Diaphoropodon archeri (Chlamydophryidae, Thecofilosea, Cercozoa), De Saedeleer 1934, and Annotations on the Polyphyly of Testate Amoebae with Agglutinated Tests in the Cercozoa

Journal of Eukaryotic Microbiology, 2018
AbstractThe genus Diaphoropodon, Archer 1869, comprises filose amoebae with agglutinated tests made of quartz grains, diatom frustules and other particulate materials. The key trait of the genus is a hyaline theca covered with numerous 5‐ to 10‐μm‐long, hairlike rods.

Saccharomycomorpha psychra n. g., n. sp., a Novel Member of Glissmonadida (Cercozoa) Isolated from Arctic and Antarctica

Journal of Eukaryotic Microbiology, 2021
A novel genus and species within the order Glissmonadida (Cercozoa, Rhizaria), Saccharomycomorpha psychra n. g., n. sp., is described from lichen in the Ny‐Ålesund region (High Arctic) and moss in the Fildes peninsula of King George Island (Maritime ...

Phylogeny and Classification of Phylum Cercozoa (Protozoa)

Protist, 2003
The protozoan phylum Cercozoa embraces numerous ancestrally biciliate zooflagellates, euglyphid and other filose testate amoebae, chlorarachnean algae, phytomyxean plant parasites (e.g. Plasmodiophora, Phagomyxa), the animal-parasitic Ascetosporea, and Gromia.
