Paramecium bursaria Chlorella viruses were observed by applying transmission electron microscopy in the native symbiotic system Paramecium bursaria (Ciliophora, Oligohymenophorea) and the green algae Chlorella (Chlorellaceae, Trebouxiophyceae). Virus particles were abundant and localized in the ciliary pits of the cortex and in the buccal cavity of P.(More)
The ciliates Paramecium bursaria contain endosymbiotic green algae Chlorella spp. in their cytoplasm. The algae isolated from P. bursaria are sensitive to large DNA-containing viruses of the family Phycodnaviridae. The type virus of this family is PBCV-1 (Paramecium bursaria Chlorella virus). Investigation of the total DNA of P. bursaria clones by(More)
New stands of Paramecium biaurelia, P. triaurelia, P. tetraurelia, P. pentaurelia, P. novaurelia, and P. dodecaurelia were recorded in Russia. Especially interesting is the record of P. novaurelia in Vladivostok, Russian Far East, as it is a very rare species outside of Europe. The distribution of species of the Paramecium aurelia complex in Eurasia with(More)
Population density has recently been suggested to be an important factor influencing metabolic rates and to represent an important 'third axis' explaining variation beyond that explained by body mass and temperature. In situations where population density influences food consumption, the immediate effect on metabolism acting through specific dynamic action(More)
The algebraic method for stream-cipher key recovering was developed in [5]. The essence of this method is in solving the system of nonlinear equations which are the simplified consequences of the enciphering equations. The different questions on this method were investigated in [5, 6, 7]. We are using the group-theory methods for justification of algebraic(More)
