The Phylogeny of Colpodellids (Alveolata) Using Small Subunit rRNA Gene Sequences Suggests They are the Free-living Sister Group to Apicomplexans
It is demonstrated that colpodellids and perkinsids are plesiomorphically similar in morphology and help provide a phylogenetic framework for inferring the combination of character states present in the last common ancestor of dinoflagellates and apicomplexans. Expand
The morphology of predatory flagellate Colpodella pseudoedax Mylnikov et Mylnikov, 2007 (Colpodellida, Alveolata)
The structure of the predatory freshwater flagellate Colpodella pseudoedax was studied. The cell was found to contain two heterodynamic flagella, three-membrane pellicle, micropores, subpellicularExpand
Biology and morphology of freshwater rapacious flagellate Colponema aff. loxodes Stein (Colponema, Alveolata)
The biology, morphology, and ultrastructure of the freshwater rapacious flagellate Colponema aff. loxodes, which attacks bodonids and chrysomonads, are studied. The flagellate is characterized byExpand
First records of centrohelid heliozoans (Centrohelida) in Mongolia
Six species of the families Raphidiophryidae Mikrjukov, 1996 and Acanthocystidae Claus, 1874 have been recorded in this region for the first time. Expand
Ultrastructure of the marine predatory flagellate Metromonas simplex Larsen et Patterson, 1990 (Cercozoa)
The ultrastructure of the marine predatory flagellate Metromonas simplex Larsen and Patterson was studied and the similarity that M. simplex shares with Metopion fluens Larsen et Patterson, cryothecomonads, and other predatory Flagellates is discussed. Expand
Changes in biological characteristics of freshwater heterotrophic flagellates and cladocerans under the effect of metal oxide nano- and microparticles
In the case of Ceriodaphnia affinis Lilljeborg, their reproductive characteristics showed a significant correlation with the concentrations of nanosize particles of the substances under consideration, and the microrparticles of titanium and cerium dioxides were less toxic than the respective nanoparticles.

The ultrathin structure of amoeboid flagellate Thaumatomastix sp. (Thaumatomonadida (Shirkina) Karpov, 1990)
Within cytoplasm, extrusive organelles (kinetocysts) containing amorphous material and capsule were found and the resemblance between Thaumatomastix sp. Expand
[The structure of extrusive organelles in alveolate and other heterotrophic flagellates].
The comparison of the data obtained confirms the hypothesis about the correlation of taxonomic position of flagellates and the structure of their extrusomes that allows in some cases using these features as phylogenetic markers. Expand
The cell structure of the reticulopodial amoeba Filoreta marina Bass et Cavalier-Smith (Cercozoa)
The cell structure of a reticulopodial amoeba, Filoreta marina Bass et Cavalier-Smith, is described and a similarity of this amoepa to other filose and reticULopodials amoEBas is discussed. Expand
The influence of cryogenic mass exchange on the distribution of viable microfauna in cryozems
The role of cryogenic mass exchange in the distribution of the viable microfauna in the profiles of cryoturbated cryogenic soils and in the upper layers of permafrost was revealed and a considerable part of the community maintained its viability in the dormant state. Expand
