Hydrographic Feature Variation Caused Pronounced Differences in Planktonic Ciliate Community in the Pacific Arctic Region in the Summer of 2016 and 2019

open access: yesFrontiers in Microbiology, 2022
Planktonic ciliates are an important component of microzooplankton, but there is limited understanding of their responses to changing environmental conditions in the Pacific Arctic Region. We investigated the variations of ciliate community structure and

The giant ciliate Zoothamnium niveum and its thiotrophic epibiont Candidatus Thiobios zoothamnicoli: a model system to study interspecies cooperation

open access: yesFrontiers in Microbiology, 2014
Symbioses between chemoautotrophic sulfur-oxidizing (thiotrophic) bacteria and protists or animals are among the most diverse and prevalent in the ocean. They are extremely difficult to maintain in aquaria and no thiotrophic symbiosis involving an animal

Epigenetic inheritance in ciliates [PDF]

open access: yesCurrent Opinion in Microbiology, 2009
2009 marks not only the 200th anniversary of Darwin's birth but also publication of the first scientific evolutionary theory, Lamarck's Philosophie Zoologique. While Lamarck embraced the notion of the inheritance of acquired characters, he did not invent it (Burkhardt, 1984).

Ciliate diversity and behavioural observations from the chemoautotrophic cave ecosystem of Frasassi, (Marche region, Italy) [PDF]

open access: yes, 2015
Chemoautotrophic cave organisms require specific adaptations to tolerate the stress of living in extreme environmental conditions, such as darkness, nutrient and energy limitations, low temperatures (12-13°C), highly variable sulphide concentrations ...

Chloroplast symbiosis in a marine ciliate: ecophysiology and the risks and rewards of hosting foreign organelles

open access: yesFrontiers in Microbiology, 2012
Simultaneous use of both heterotrophic and autotrophic metabolism (mixotrophy) is common among protists. Strombidium rassoulzadegani is a planktonic mixotrophic marine ciliate that saves chloroplasts from its algal food and obtains a nutritional subsidy

Balantidium grimi n. sp. (Ciliophora, Litostomatea), a new species inhabiting the rectum of the frog Quasipaa spinosa from Lishui, China

open access: yesParasite, 2018
Balantidium grimi n. sp. is described from the rectum of the frog Quasipaa spinosa (Amphibia, Dicroglossidae) from Lishui, Zhejiang Province, China. The new species is described by both light microscopy (LM) and scanning electron microscopy (SEM), and a ...

Top-down control of planktonic ciliates by microcrustacean predators is stronger in lakes than in the ocean

open access: yesScientific Reports, 2022
Planktonic ciliates are major components of pelagic food webs in both marine and freshwaters. Their population dynamics are controlled ‘bottom-up’ by prey availability and ‘top-down’ by microcrustacean predators.

A strategy for complete telomere-to-telomere assembly of ciliate macronuclear genome using ultra-high coverage Nanopore data

open access: yesComputational and Structural Biotechnology Journal, 2021
Ciliates contain two kinds of nuclei: the germline micronucleus (MIC) and the somatic macronucleus (MAC) in a single cell. The MAC usually have fragmented chromosomes.

Distribution of Abundant and Active Planktonic Ciliates in Coastal and Slope Waters Off New England

open access: yesFrontiers in Microbiology, 2017
Despite their important role of linking microbial and classic marine food webs, data on biogeographical patterns of microbial eukaryotic grazers are limited, and even fewer studies have used molecular tools to assess active (i.e., those expressing genes)
