Local ciliate communities associated with aquatic macrophytes [PDF]

open access: yes, 2014
This study, based within the catchment area of the River Frome, an important chalk stream in the south of England, compared ciliated protozoan communities associated with three species of aquatic macrophyte common to lotic habitats: Ranunculus ...

Phenotypic Polymorphism in Two Endosymbiotic Bacteria of the Ciliate Paramecium: Pseudolyticum multiflagellatum and “Ca. Megaira venefica”

open access: yesDiversity, 2023
Here, we report a comprehensive description of the stable associations between two Paramecium species (P. nephridiatum and P. caudatum) and their cytoplasmic bacterial endosymbiont Pseudolyticum multiflagellatum.

Biological evaluation of honey

open access: yesRUDN Journal of Agronomy and Animal Industries, 2013
The article shows the results of the use of ciliates Tetrahymena pyriformis, for biological evaluation of honey. It is known that ciliates Tetrahymena pyriformis, similar in general characteristics of metabolism with higher animals, can serve as ...

Experimental Evolution in Tetrahymena

open access: yesMicroorganisms, 2022
Experimental evolution has provided novel insight into a wide array of biological processes. Species in the genus Tetrahymena are proving to be a highly useful system for studying a range of questions using experimental evolution.

The diversity and ecological role of protozoa in fresh waters [PDF]

open access: yes, 1997
Protozoa feed on and regulate the abundance of most types of aquatic microorganisms, and they are an integral part of all aquatic microbial food webs. Being so small, aerobic protozoa thrive at low oxygen tensions, where they feed (largely unaffected by ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Accumulation of Tetrahymena pyriformis on Interfaces

open access: yesMicromachines, 2021
The behavior of ciliates has been studied for many years through environmental biology and the ethology of microorganisms, and recent hydrodynamic studies of microswimmers have greatly advanced our understanding of the behavioral dynamics at the single ...

Wall Drag on Free-Moving Ciliated Micro-Organisms [PDF]

open access: yes, 1973
It is generally assumed that wall drag on free-moving, self-propelled or passively moving micro-organisms is not significant under normal observation conditions. Yet the point at which such drag becomes significant has not been determined quantitatively.

Integrating functional diversity, food web processes, and biogeochemical carbon fluxes into a conceptual approach for modeling the upper ocean in a high-CO2 world [PDF]

open access: yes, 2005
Marine food webs influence climate by channeling carbon below the permanent pycnocline, where it can be sequestered. Because most of the organic matter exported from the euphotic zone is remineralized within the "upper ocean" (i.e., the water column ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

open access: yesFEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...
