Ciliophora - an overview | ScienceDirect Topics
Ciliates were found in Simulium tuberosum larvae and in the larval, pupal, and adult stages of Simulium venustumn. Hosts typically harbored around 10 ciliates, a number far less than generally reported for ciliate-infected dipterans ( Lynn et al. , 1981 ).
Functional diversity of aquatic ciliates - ScienceDirect
2017年10月1日 · This paper first reviews the concept of functional diversity in general terms and then applies it to free-living aquatic ciliates. Ciliates are extremely versatile organisms and display an enormous functional diversity as key elements of pelagic food webs, acting as predators of bacteria, algae, other protists and even some metazoans.
Ciliates (Alveolata, Ciliophora) as bioindicators of environmental ...
2021年5月1日 · These ciliates are quite abundant in diverse freshwater habitats, especially in plankton (as they can consume up to 100% of the standing stock of nanoplankton every day) (Thorp and Covich, 2010, Grattepanche et al., 2019). Also, they can be easily morphologically identified due to their prominent adoral zone of membranelles.
Chapter 23 - Symbiotic microbes from ciliates - ScienceDirect
2023年1月1日 · Ciliates (Ciliophora, Alveolata) of the protist community are the best candidates for this purpose of investigation due to their presence in different moist ecosystems including anoxic sediments, hydrothermal vents, hyporheic zones, coastal water columns, oxic and anoxic parts of the water columns and are the abundant phagotrophs in the ...
An improved method for tubulin staining of ciliated eukaryotes
2024年7月1日 · Ciliated microeukaryotes (ciliates) are distinguished by their cilia, which are rich in tubulin. We developed a method for tubulin staining in ciliate cells that involves using live-cell tubulin-staining dyes instead of antibodies thereby streamlining the staining process, which is effective across diverse ciliate lineages.
Small RNA-mediated genome rearrangement pathways in ciliates
2023年2月1日 · Ciliates have evolved diverse pathways involving RNA-mediated epigenetic mechanisms to ensure the complete elimination of transposons. The separation of germline and somatic functions into distinct nuclei in the same cytoplasm, a feature known as nuclear dimorphism, is what makes this alternative approach possible (reviewed in [ 5 ]).
Feeding behaviour in ciliated protists - ScienceDirect
1997年12月1日 · Rumen ciliates Rumen ciliates (Litostomatea, Trichostomatia) live as endosymbionts in the tureen of ruminants [Fig. 13(b)]. They engulf bacteria, other ciliates, forage and non- living particles, since they can utilize cellulose, hemi- cellulose, fructosan, starch, soluble sugar and lipids (Coleman and Laurie, 1974). 4.1. Food capture.
The relative roles of multiple drivers on benthic ciliate …
2023年2月1日 · Ciliates are unicellular protozoa and one of the most diverse organism groups in benthic ecosystems (Fenchel, 2012). As essential components of benthic microbial food webs, benthic ciliates play a key role in transferring primary production to higher nutrient levels (Agasild et al., 2013; Kamjunke et al., 2012; Rollwagen-Bollens et al., 2013).
Foam flotation can remove and eradicate ciliates contaminating …
2018年1月1日 · The numbers of ciliates in the foamate and the Removal Efficiency (RE) were determined using Eqs. (1), (2) respectively. (1) Ciliates in foamate = A − B cells mL − 1 where: A is the initial ciliates count prior to each run, and B is the final ciliates count after each run. (2) RE = Ciliates in foamate Initial ciliates count × 100. 2.4.
Ciliates as bioindicators of water quality: A case study in the ...
2021年1月1日 · To quantify ciliates, we analyzed three 200 μl aliquots from each sample (five replicates for each sample) under the optical microscope with a 400x zoom (Madoni, 1984). To cultivate ciliates, we used three aliquots of 20 ml aliquots from each sample. These were kept in petri dishes with fresh water and mashed, unpeeled rice grains.
