between them. Morphological analysis of selected strains from the major clade, which we consider as the genus Monocercomonoides, failed to find suitable characters for species delineation and it is also very difficult to assign lineages to described species. Based on the morphology and host origin, we assume that the lineage containing Chinchilla isolate PA203, and isolates from guinea pig and Chameleo cristatus represent species M. exilis.
CILIOFAUNA OF NATURAL AND ARTIFICIAL ECOSYSTEMS OF KHABAROVSK TERRITORY

Environmental degradation due to pollution by industrial, agricultural and municipal waste gave rise to serious problems, associated with the violation of the ecological balance in ecosystems and the biosphere. Ciliata - an important object in the model laboratory experiments, as they are used as an indicator of the degree of human impact on the environment. Sampling was carried out in small rivers of the Khabarovsk territory (rivers Krasnaya, Chernaya, Berezovaya) and aeration tanks in Khabarovsk (town Berezovii). During inventory ciliofauna has been identified 152 species of ciliates. The greatest number of species represented Oligohymenophorea class - 33 and Vorticellidae family - 12 species. 3 species of ciliates were eurybiontic (Paramecium caudatum, Colpidium campylym, Uronema marinum). Species ciliofauna similarity between small rivers and aeration tanks is 30% (according to Sorensen coefficient). Ciliata specific types of small rivers Khabarovsk - 14 (32% of the number of species recorded in small rivers), in aeration tanks - 32 (57%). Specific types belonged Armophorea classes - 3 kinds, Litostomatea - 3 kinds, Phyllopharyngea - 8 species, Oligohymenophorea - 13 species. Thus, faunal analysis of ciliofauna aquatic ecosystems Khabarovsk shows how the presence of similar species found in a variety of biological communities and the presence of specific representatives. In particular, this phenomenon is characteristic of biocenosis aeration.

Mitochondria are important organelles in all eukaryotes and their protein composition and function(s) depend on the lifestyle of the organism harboring them. While being very well studied, their functional distribution amongst ciliates remains a dark box. The Ciliophora group is currently one of the most studied lineages of single-cell eukaryotes, mainly due to their abundance in diverse habitats. Despite this, investigations on the cell biology and the functional diversification of their organelles have been limited, with the exception of certain species, mainly Paramecium, Tetrahymena and Nyctotherus. These organisms have been shown to harbor either typical mitochondria or hydrogen-producing mitochondria, while their mitochondrial genome has an unusual codon usage. In this project, we used the recently acquired transcriptomic and genomic data to predict the functional diversity of mitochondria and related organelles within the group of ciliates. Our analyses demonstrate that members of the ciliates harbor distinctive classes of mitochondria, with a variety of functions and adaptations. Two species have been predicted to have remnant mitochondria (mitosomes) and one of them hydrogen-producing mitochondria (hydrogenosomes). Surprisingly, we are currently observing the whole spectrum of functional classification of mitochondria just within ciliates; Ciliophora is an exceptional model group to monitor in real time the functional adaptations of mitochondria.

Testate amoeba transfer functions are widely used for reconstruction ofpalaeo-hydrological regime in peatlands. However, the limitations ofthis approach have become apparent with increasing attention to validation and assessing sources of uncertainty. This paper investigates effects of peatland type and
