This article deals with the formation of symbiotic communities in a waterbody of the Ptich’ya Gavan nature park (Omsk) at the end of May 2010. The samples were collected by plankton nets, fixed in formalin, and examined with the use of optical microscope. The symbiotic communities consist of ciliates Ophrydium versatile and 35 other species and forms of(More)
The species composition and dynamics of cyanobacteria and algae inhabiting the ice of Lake Kalach (Omsk oblast) have been studied. High abundance and a low floristic similarity with phytoplankton have been discovered. Small-celled cyanobacteria and chlorococcales dominate in number of species and abundance. A new term, “cryophyton,” is proposed for(More)
Light and scanning electron microscopy studies of centric diatoms of the plankton in the middle Irtysh River and waterbodies and water courses of its basin have revealed 21 taxa of Centrophyceae from 9 genera, including 14 new for the region. A revision of the species composition allowed us to specify and broaden the list of centric diatoms in the Omsk(More)
The distribution of stomatocysts of chrysophyte algae in the plankton of bodies of water of different types in the basin of the middle reach of the Irtysh (at the Omsk Region), as well as in the plankton and in fouling of the deep-water oligotrophic lake Teletskoe (Gorny Altai) has been considered. The classification of morphotypes of stomatocysts has been(More)
