On plastid symbiosis in Tontonia appendiculariformis (Ciliophora, Oligotrichina)
Biosystems, 1986Many hundreds of isolated plastids, in a good state of preservation in their living host, the planktonic ciliate Tontonia appendiculariformis (Oligotrichina), have been studied by electron microscopy. These distinctive plastids, located at the periphery of the host's body, which do not belong to complete symbiotic algae, are described in detail.

A new macrosystem for the phylum ciliophora doflein, 1901
Biosystems, 1981A new macrosystem for the phylum Ciliophora is described. It is based primarily on the concept of the structural conservatism of the cortical fibrillar structures. Three subphyla, the Postciliodesmatophora, Rhabdophora, and Cyrtophora, are described. These three subphyla are divided respectively into the following classes: (1) the Postciliodesmatophora,

Morphogenesis in some freshwater Tintinnids (Ciliophora, Oligotrichida)
European Journal of Protistology, 1993The morphogenesis of four freshwater tintinnids was investigated using protargol silver impregnation and scanning electron microscopy. Division is rather similar in Tintinnopsis cylindrata, Tintinnidium pusillum and T. semiciliatum, e.g. the oral primordium develops apokinetally posterior of somatic kinety 10 and the somatic ciliature originates by two

Euplotes uncinatus (Ciliophora, Hypotrichia), a new species with zooxanthellae [PDF]
Marine Biology, 2005 During the observations of a field collection of Maristentor dinoferus with fluorescence microscopy, we discovered a smaller ciliate with zooxanthellae. On the basis of morphological, morphometric and ultrastructural characters, this ciliate has been recognized as a new species of the genus Euplotes. To emphasize the peculiar shape and extension of the

Nuclear characteristics and phylogeny in the Protistan phylum ciliophora
Biosystems, 1975Ciliates possess a number of nuclear characteristics which, in combination, are unique among the Protista. Nevertheless, attempts to understand the origin - presumably from a flagellate ancestry - of the Ciliophora as a phylum must be made, as well as efforts to elucidate phylogenetic pathways within the large and diverse assemblage represented by its ...

Molecular phylogeny of unculturable Karyorelictea (Alveolata, Ciliophora)
Zoologica Scripta, 2009Karyorelictea is a class of traditionally unculturable ciliates characterized by a non‐dividing macronucleus. Their classification has been recently revised and morphological redescription of many species has been performed as well. On the contrary, molecular data of karyorelictean ciliates are largely underrepresented in public databases.

Intraspecies differentiation of Paramecium sexaurelia (ciliophora)
Archiv für Protistenkunde, 1990Summary Two strains originating from different habitats in Sevilla (Spain) were identified as Paramecium sexaurelia from the Paramecium aurelia species complex. It was the first finding of this species in Europe. Both Spanish strains can interbreed, showing a high percentage of surviving clones in F1 and F2 of their hybrids.

Diversity and geographic distribution of ciliates (Protista: Ciliophora)
Biodiversity and Conservation, 2007About 4,500 free-living ciliate morphospecies have been described, applying an average synonymy rate of 20%. We estimate that 83–89% of the ciliate diversity is still undescribed, using the following probabilities: detailed habitat studies suggest that the described number of morphospecies must be doubled: 4,500 → 9,000; this figure has to be increased

Miscellanea Nomenclatorica Ciliatea (Protozoa: Ciliophora)
Archiv für Protistenkunde, 1987Summary Some nomenclatural rectifications and new combinations in the phylum Ciliophora are suggested. In addition, the correct date and citation of the genera Coleps, Gastronauta, Pseudop-rorodon, and Steinia and of the species Epistylis entzii, Kahliella microstoma, Oxytricha buitkampi, Plagiotoma lumbrici, Stokesia vernalis, and Trithigmostoma ...

Resting cysts: A survival strategy in Protozoa Ciliophora
Italian Journal of Zoology, 2011Abstract Encystment is a reversible cell differentiation process that also requires an antagonistic process, i.e. excystment. Both processes are genetically encoded. Encystment is of common occurrence among free-living ciliates and may serve several different purposes. In some ciliates, this process is part of the regular life cycle (reproductive cyst),
