Flagellated endosymbiotic bacteria in a marine Frontonia sp. (Oligohymenophorea, Peniculida)

Protistology, 2001
Frontonia sp. was repeatedly found in sea water samples collected from a shore near Leghorn (Ligurian sea). Endosymbiotic rod shaped bacteria 5-6 μm long were found in the cytoplasm of each Frontonia sp. specimen examined at the fluorescent microscope following DAPI staining procedure.

Adaptation of Marine Heterotrophic Protists to Long‐Term Warming Selection

Global Change Biology, Volume 31, Issue 6, June 2025.
Our study unraveled profitable adaptations of marine protozoa to long‐term warming. The optimal temperature, maximum growth rates, cell homeostasis, and cell size significantly increased after warming adaptation, suggesting a resilient future for this functional group.

Unclear host taxonomy hinders parasite studies: An up‐to‐date checklist of the protozoan and metazoan parasites of Phoxinus minnows (Teleostei: Leuciscidae)

Journal of Fish Biology, Volume 105, Issue 6, Page 1501-1539, December 2024.
Abstract Phoxinus minnows are small freshwater fish found throughout Eurasia. The taxonomy of this genus is still under investigation, and new species are regularly described. They are frequently introduced outside their native range due to their use as live bait for angling, and such fish introductions can have diverse impacts on the recipient areas ...

Geochemical and microbiological variability of aerobic and anaerobic sediments along a bifurcated sulphate‐saturated brine spring in western Canada

The Depositional Record, Volume 10, Issue 5, Page 637-669, November 2024.
A tufa mound developed in north‐east Alberta is characterised by an unusual emplacement of a gypsum caprock. This two‐tiered architecture resulted from the bicarbonate‐saturated groundwater flow along Upper Devonian limestone being redirected deeper and encountering the halite–anhydrite dissolution trend within the underlying Prairie Evaporite ...

Use of eDNA and conventional sampling methods to survey rock pool (gnamma) biodiversity on granite inselbergs

Austral Ecology, Volume 49, Issue 8, August 2024.
Environmental DNA sampling coupled with high‐throughput sequencing is increasingly recognized as a useful method for assessing biodiversity with potential applications in terrestrial environments. Rock pools on granite inselbergs support diverse aquatic communities, yet the application of eDNA to document their biodiversity is lacking.

Systematic positions and taxonomy of two freshwater ciliates found in China, with establishments of one new family and two new species (Ciliophora, Oligohymenophorea)

European Journal of Taxonomy
The morphology and molecular phylogeny of two freshwater ciliates, Pseudotetrahymena orientalis gen. et sp. nov. and Cyclidium paravorax sp. nov., collected from Harbin, Northeast China, were investigated based on morphology of live specimens and ...

Traits mediate environmental responses of benthic ciliates in dynamic coastal habitats

Diversity and Distributions, Volume 30, Issue 8, August 2024.
Abstract Aim Understanding how species' traits mediate environmental responses provides a mechanistic perspective on community assembly processes. Although traits that influence the response of multicellular organisms to environments have been studied, the identification of such traits in unicellular organisms, like ciliates, is underexplored.

Morphological Redesription of A Freshwater Ciliate Paramoecium Caudatum (Ciliophora: Oligohymenophorea) From Saradwadi Dam

, 2023
Abstract:  Total 35 water samples were collected from Saradwadi dam, located near Sinnar, Nashik district, Maharashtra, India. Samples were collected for the period from December 2021 to April 2022. During the present investigation a free-living freshwater ciliate Paramoecium caudatum was found and identified morphologically.

Fluorescently labeled prey surrogates in combination with fluorescence‐activated cell sorting successfully discriminate actively feeding mixotrophs in a lake water sample

Limnology and Oceanography, Volume 69, Issue 5, Page 1030-1044, May 2024.
Abstract Mixotrophic protists are capable of acting both as primary producers and primary consumers at the base of the aquatic food web, thus constituting key organisms in ecosystems where they are abundant. However, their identity, abundance, ecological dynamics, and biogeochemical impact in aquatic ecosystems remain understudied in comparison to ...
