Peritrichs (Ciliophora, Peritrichia) in the Danube: Keystone Organisms in the Formation of Diverse Protist Biofilms [PDF]

Environmental Microbiology Reports
Colonial peritrichs act as physical ecosystem engineers in middle Danube biofilms, generating three‐dimensional structures during 1–28 days of colonisation. Their surfaces host filter feeder epibionts (choanoflagellates, other peritrichs, rotifers), expanding filtration capacity and promoting functional group establishment including swimming and ...

Integrative Studies on a New Ciliate Campanella sinica n. sp. (Protista, Ciliophora, Peritrichia) Based on the Morphological and Molecular Data, With Notes on the Phylogeny and Systematics of the Family Epistylididae [PDF]

Frontiers in Microbiology, 2021
During an investigation on freshwater peritrichs, a new colonial sessilid ciliate, Campanella sinica n. sp., was isolated from aquatic plants in an artificial freshwater pond in Qingdao, China. Specimen observations of this species were performed both in

Single-Cell Genomic Sequencing of Three Peritrichs (Protista, Ciliophora) Reveals Less Biased Stop Codon Usage and More Prevalent Programmed Ribosomal Frameshifting Than in Other Ciliates

Frontiers in Marine Science, 2020
Peritrichs are one of the largest groups of ciliates with over 1,000 species described so far. However, their genomic features are largely unknown. By single-cell genomic sequencing, we acquired the genomic data of three sessilid peritrichs (Cothurnia ...

Picoplankton feeding by the ciliate Vorticella similis in comparison to other peritrichs emphasizes their significance in the water purification process

Ecological Indicators, 2021
We measured the feeding and growth rates of the sessile peritrich ciliate Vorticella similis on seven picocyanobacterial strains and their accompanying bacterial flora in microcosm experiments.

Retention of microplastics by biofilms and their ingestion by protists in rivers. [PDF]

Environ Microbiol Rep
Biofilms, which are ubiquitous in aquatic ecosystems such as rivers, may play an essential role in the fate of microplastics (MPs) and their ingestion by biofilm protists. A combination of field and laboratory experiments shows that riverine biofilms contain up to 10 times more MPs than ambient water and retain 6–12 times more MPs than surfaces without

From Mud to Meat: Comparative Metabarcoding Reveals Two Different Evolutionary Paths to Carnivory in a Group of Meiofaunal Annelids. [PDF]

Mol Ecol
ABSTRACT Evolutionary transitions to carnivory represent profound shifts in feeding mode that are often accompanied by widespread changes in organismal function, behaviour and ecology. Such transitions have evolved numerous times among animals, and predator–prey interactions have been major drivers of animal evolution.

Comparative genomics of a vertically transmitted thiotrophic bacterial ectosymbiont and its close free-living relative. [PDF]

Mol Ecol Resour
Abstract Thiotrophic symbioses between sulphur‐oxidizing bacteria and various unicellular and metazoan eukaryotes are widespread in reducing marine environments. The giant colonial ciliate Zoothamnium niveum, however, is the only host of thioautotrophic symbionts that has been cultivated along with its symbiont, the vertically transmitted ectosymbiont ...

Effect of Cothurnia variabilis and Epistylis gammari (Ciliophora: Peritrichia) on Metabolic Rate of the Crayfish Cambarellus (Cambarellus) montezumae

Diversity, 2021
Peritrichs usually settle on the external surface and gills of crustaceans. However, their physiological effect on the host has not been studied. Respiratory rate is a susceptible index for some factors that affect an organism.

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.
