Vampyrella crystallifera sp. nov., an Amoeba That Dissolves Entire Algal Cells at a Remarkable Speed

Ecology and Evolution
The vampyrellid amoebae (Order Vampyrellida, Rhizaria) comprise predatory microeukaryotes that inhabit freshwater, marine, and terrestrial habitats. They are known to consume a wide array of prey, which includes microalgae, fungi, and even microscopic ...

Seasonality regulates the taxonomic and functional compositions of protists responding to climate warming in forest ecosystems

Journal of Sustainable Agriculture and Environment, Volume 2, Issue 4, Page 529-540, December 2023., 2023
Abstract Introduction Protists are unicellular eukaryotes including important predators, parasites and phototrophs, and play pivotal roles in organic matter decomposition, biogeochemical nutrient cycling and various ecosystem functions. Unravelling the impact of climate warming on soil protists is paramount in predicting how these microorganisms will ...

Diversity of ‘simple’ multicellular eukaryotes: 45 independent cases and six types of multicellularity

Biological Reviews, Volume 98, Issue 6, Page 2188-2209, December 2023., 2023
ABSTRACT Multicellularity evolved multiple times in the history of life, with most reviewers agreeing that it appeared at least 20 times in eukaryotes. However, a specific list of multicellular eukaryotes with clear criteria for inclusion has not yet been published.

18S rDNA gene metabarcoding of microeukaryotes and epi‐endophytes in the holobiome of seven species of large brown algae

Journal of Phycology, Volume 59, Issue 5, Page 859-878, October 2023., 2023
Abstract Brown algae (Phaeophyceae) are habitat‐forming species in coastal ecosystems and include kelp forests and seaweed beds that support a wide diversity of marine life. Host‐associated microbial communities are an integral part of phaeophyte biology, and whereas the bacterial microbial partners have received considerable attention, the microbial ...

Xenophyophore-associated mitogenomes: genomic investigations of two specimens from the Clarion-Clipperton Zone

Frontiers in Marine Science
IntroductionXenophyophores are large benthic agglutinated Foraminifera that are a major component of the Clarion-Clipperton Zone megafauna.MethodsTwo xenophyophore specimens were obtained and submitted to genomic investigations.ResultsFor both specimens,

Metabarcoding of Broad‐Diet Nototheniid Fish Stomachs Reveals Newly Detected Antarctic Parasite Signals and Potential Host Associations

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Using 18S rDNA metabarcoding of stomach contents from two Antarctic nototheniid fishes, we detected 242 parasite OTUs. Protists dominated diversity, metazoans dominated abundance, and depth structured assemblages. Novel parasite–host associations and previously unreported pathogenic protists highlight fish metabarcoding as a tool for biodiversity and ...

A Novel Protistan Trait Database Reveals Functional Redundancy and Complementarity in Terrestrial Protists (Amoebozoa and Rhizaria)

Molecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT The inclusion of functional traits of protists in environmental sequencing surveys, in addition to the traditional taxonomic framework, is essential for a better understanding of their roles and impacts on ecosystem processes. We provide a database of functional traits for a widespread and important clade of protists—the Amoebozoa—based on ...
