Phytoplankton samples from the Verkhnaya Angara and Kichera rivers as well as from the Dushkachanskoye, Sredneye and Dagarskoye mouths, were investigated by means of scanning electron microscopy. Among 58 chrysophyte stomatocysts found in the samples, 25 are described as new to science. C помощью сканирующей электронной микроскопии в устьях рек Кичера, Верхняя Ангара, а также в Душкачанском, Среднем и Дагарском устьях Ангаро-Кичерской дельты, обнаружено 58 стоматоцист хризофитовых, из которых 25 описаны как новые. Ключевые слова: Стоматоцисты хризофитовых; река Кичера; река Верхняя Ангара; Ангаро-Кичерская дельта; Северный Байкал Введение Реки Кичера и Верхняя Ангара являются крупными притоками Северного Байкала (Baikal. Atlas, 1995). Они образуют в нижнем течении общую дельту, отделяясь от Байкала узким песчаным островом Ярки и сообщаясь с озером через три устья (прорвы), которые разделяют этот остров -Душкачанское, Среднее и Дагарское (Votintsev, Glazunov, Tolmacheva, 1965).Золотистые водоросли (хризофитовые) являются важнейшим компонентом фитопланктона олиготрофных озер. Одной из особенностей этих организмов является образование стоматоцист в конце вегетации или вследствие наступления неблагоприятных условий. Стоматоцисты часто используют как биомаркеры в палеолимнологических и палеоэкологических исследованиях, поскольку они сохраняются в донных отложениях. По особенностям формы и поверхностной орнаментации, выявляемой с помощью сканирующей электронной микроскопии (СЭМ), стоматоцисты описываются как морфотипы, поскольку только небольшая часть их отнесена к определенным видам хризофитовых.

“…It is known that in eutrophic water bodies as well as in shallow pools the smooth forms of chrysophycean cysts mostly prevail. This is different in oligotrophic and deep pools, where forms with different elements on the surface dominate, which provides their floating in the water column (Bazhenova et al, 2012). Similar to diatoms, cysts of chrysophycean algae and spores of ferns and Table 3.…”

Biological proxies recorded in a Belukha ice core, Russian Altai

et al. 2013

Abstract. Different biological proxies such as pollen, cysts, and diatoms were identified and quantified in the upper part of a Belukha ice core from the Russian Altai. The ice core from the Belukha glacier collected in 2001 (4062 m a.s.l., 49 • 48 N, 86 • 34 E) was analyzed with annual resolution in the period . Daily data of the frequency of synoptic patterns observed in the Northern Hemisphere along with daily data of precipitation have been used to identify the predominant atmospheric circulations (elementary circulating mechanisms, or ECMs) generating the entry of biological proxies on the glacier surface. It was shown that the high-resolution records of diatoms, cysts, spores, and plant pollen in the Belukha ice core are the biological proxies for the changes in the structure of precipitation in the Altai region since these records can reflect changes in the contribution of different atmospheric circulation to annual or seasonal precipitation. The joint consideration of the transport ability of the biological species and the data of precipitation allowed us to determine the main modern sources of biological proxies deposited at the Belukha glacier. The main sources of diatoms in the Belukha ice core are water bodies of the Aral, Caspian, and northern Kazakhstan basins; coniferous tree pollen originated from the taiga forest of the boreal zone of western Siberia; pollen of deciduous trees and herbs from steppe and forest-steppe vegetation in the northern Altai and eastern Kazakhstan; and cysts and spores of plants were transported from local water bodies and forests. The identified source regions of the biological species are supported by back trajectory analyses and are in good agreement with emission source regions of the trace elements in the ice core.

Abstract. The review examines the work on biodiversity in the reservoirs of Eastern Siberia of a wide, but poorly studied group of organisms forming siliceous scales and bristles these are scaled chrysophytes, chrysophycean stomatocysts and heterotrophic protists: rotosphaerids, colorless free-living thaumatomonad flagellates, centrohelid heliozoans. The difficulty in studying these objects is the need to use electron microscopy for their species identification. High biodiversity of silica scaled Protozoa has been revealed in the reservoirs of Eastern Siberia and the relationship of their species composition with the parameters of the aquatic environment, including in areas of local anthropogenic impact, has been shown. The recorded enrichment of the mouths of Arctic rivers with boreal species is important for predicting changes in aquatic ecosystems in the context of GCC. The proposed scenario of the settlement of siliceous chrysophytes at the beginning of the Holocene may be valid for other small planktonic organisms. The high degree of preservation of siliceous stomatocysts in sediments allows them to be used as an additional signal of changes in lake ecosystems in the past, this is based in particular on the reconstruction of the ecosystem and changes in the level of Lake Vorota (Yakutia) in the Holocene-Upper Pleistocene.
