Reticulamoeba is a long-branched Granofilosean (Cercozoa) that is missing from sequence databases. [PDF]

PLoS ONE, 2012
We sequenced the 18S ribosomal RNA gene of seven isolates of the enigmatic marine amoeboflagellate Reticulamoeba Grell, which resolved into four genetically distinct Reticulamoeba lineages, two of which correspond to R. gemmipara Grell and R. minor Grell,

Freshwater and Sediment Host Distinct Yet Overlapping Microeukaryotic Communities, With Sediment Communities Less Impacted by Treated Wastewater. [PDF]

J Eukaryot Microbiol
ABSTRACT Freshwater and sediment environments host diverse microeukaryotic communities that differ in structure and composition, yet exhibit taxonomic overlap. Using 18S V9 rRNA gene sequencing, we compared communities from these habitats in controlled 10‐day mesocosm experiments, examining diversity, overlap, and responses to treated wastewater (TWW).

Revised Small Subunit rRNA Analysis Provides Further Evidence that Foraminifera Are Related to Cercozoa [PDF]

Journal of Molecular Evolution, 2003
There is accumulating evidence that the general shape of the ribosomal DNA-based phylogeny of Eukaryotes is strongly biased by the long-branch attraction phenomenon, leading to an artifactual basal clustering of groups that are probably highly derived. Among these groups, Foraminifera are of particular interest, because their deep phylogenetic position

Local diversity of heathland Cercozoa explored by in-depth sequencing [PDF]

The ISME Journal, 2016
Cercozoa are abundant free-living soil protozoa and quantitatively important in soil food webs; yet, targeted high-throughput sequencing (HTS) has not yet been applied to this group.

From Forest Soil to the Canopy: Increased Habitat Diversity Does Not Increase Species Richness of Cercozoa and Oomycota in Tree Canopies

Frontiers in Microbiology, 2020
Tree canopies provide habitats for diverse and until now, still poorly characterized communities of microbial eukaryotes. One of the most general patterns in community ecology is the increase in species richness with increasing habitat diversity.

Discocelia Plataet Sp. n., a Small Incertae Sedis Cercozoan Flagellate. [PDF]

J Eukaryot Microbiol
ABSTRACT Cercozoa = Filosa (Rhizaria, SAR) is one of the largest rhizarian subgroups and consists of a diverse assemblage of amoeboid and flagellated protists. They are ecologically significant in microbial food webs, widely diverse, and even abundant in soils and deep marine sediments according to environmental sequencing.

Functional Traits and Spatio-Temporal Structure of a Major Group of Soil Protists (Rhizaria: Cercozoa) in a Temperate Grassland

Frontiers in Microbiology, 2019
Soil protists are increasingly appreciated as essential components of soil foodwebs; however, there is a dearth of information on the factors structuring their communities. Here we investigate the importance of different biotic and abiotic factors as key

Protistan Plankton Responses to Variable Light and Upwelling in the Peruvian Humboldt Current System: Insights Into Community Dynamics Under Environmental Change. [PDF]

Ecol Evol
Our study reveals (based on experiments) the shifts in protistan plankton communities, serving as energy and organic matter source for higher trophic levels if the Humboldt Current System is affected by climate change as predicted by current models. This may have profound effects on fisheries in the Humboldt Current System.

Association Between PFAS Contamination and Zooplankton Community Structure in the Weihe River, China [PDF]

Toxics
Understanding the structure of zooplankton communities in water contaminated with per- and polyfluoroalkyl substances (PFAS) is essential to the conservation of aquatic biodiversity.

High Diversity Revealed in Leaf‐Associated Protists (Rhizaria: Cercozoa) of Brassicaceae [PDF]

Journal of Eukaryotic Microbiology, 2016
The largest biological surface on earth is formed by plant leaves. These leaf surfaces are colonized by a specialized suite of leaf‐inhabiting microorganisms, recently termed “phyllosphere microbiome”. Microbial prey, however, attract microbial predators.
