“…The water temperature varied from 19.5 to 35.2 °C. In terms of water mineralization, the studied lakes may be divided into three groups: oligohaline lakes having water mineralization of 0.7–4.2 g l −1 , mesohaline lakes with water mineralization of 5.0–16.2 g l −1 , and polyhaline lakes with mineralization over 20 g l −1 (Itigilova et al, 2014). The dominant cation was sodium, hydrocarbonate was the dominant anion, chloride was the sub-dominant anion with increasing mineralization (Sklyarov et al, 2011) (Table 1).…”

“…Our studies of the plankton community (algae and invertebrates) in 16 saline lakes were carried out in July 2011. Some abiotic environmental parameters (temperature, pH, dissolved oxygen, mineralization) were measured using an AQUAMETER 200TM device (Itigilova et al, 2014). Water transparency was measured by Secchi disk.…”

“…Fluctuations in environmental factors lead to changes in species diversity and structure characteristics in communities of aquatic organisms. During low water dry years (2008), when compared to high water 1966 and 1993, the lake depths decreased and water mineralization increased (Itigilova et al, 2014). Information on the changes in the ecological conditions in the lakes is presented in the published papers (Dulmaa, 1966, Sheveleva et al, 2009; Dorofeyuk and Tsetsegma, 2014.).…”

The plankton community of sixteen saline lakes located on Onon-Torey plain (Northeastern Mongolia) during the filling phase and the raising of the water level was investigated in July 2011. Thirty-five taxa of phytoplankton and thirty-one species of zooplankton were found. For phytoplankton, blue-green algae (, ,, , sp., sp.) and green algae (, ,, sp.) were dominant. For zooplankton,, , (Rotifera), ,, (Cladocera),, , (Copepoda) dominated. Mineralization, active hydrogen ratio, dissolved oxygen and water temperature were the main factors influencing the diversity, structure and distribution of plankton organisms in the steppe lakes during low water level. The RDA analysis for phytoplankton and zooplankton from different lakes was carried out for selected two groups which included lakes and a subset related species. The first group is of oligohaline and mesohaline lakes in which mostly green algae, rotifers and copepods inhabit. The second group is of mesohaline and polyhaline lakes with mainly blue-green algae some crustaceans and rotifers inhabiting. High abundance and biomass of , sp. and were observed in lakes with high mineralization, pH and temperature.

“…The ecosystem of Lake Zun-Torey follows the trend common for salt lakes, where lower water levels lead to a higher salinity and pH and, hence, to poorer species diversity (Gorlacheva et al, 2014;Itigilova et al, 2014). As the chemical properties of the water change, the total numbers and biomass of aquatic organisms may either increase (Echaniz, Vignatti, 2011;Vignatti et al, 2017) or decrease (Balushkina et al, 2009;Litvinenko et al, 2013).…”

Lakes Barun-Torey and Zun-Torey are the largest water bodies in Zabaikalsky Krai, and they are characterized by long-term cyclic changes in the water level. Samples of the planktonic community (algae and invertebrates) were collected from the Torey Lakes in June, August, and October in the dry 2016. Collection and processing of the samples was carried out using standard hydrobiological methods. The aim of the study was to investigate the planktonic communities in the Torey Lakes. The lakes were in different hydrological phases: Barun-Torey was in the initial filling phase (with isolated small lakes present on the dried bed), and Zun-Torey was in the shallowing phase. Considerable differences were observed between the compositions and structures of the planktonic communities, which were determined by the mineral content of the water. Diverse littoral plankton developed, consisting of 2-25 taxa of algae (total number of taxa -46) and 2-15 species of invertebrates (total number of species -29) in the oligohaline small lakes on the bottom of Lake Barun-Torey. The abundance and biomass of aquatic organisms varied within very wide limits: for phytoplanktonfrom 0.7 × 10 3 to 1260.0 × 10 3 cells / L and from 0.1 to 1271.0 mg / m 3 , and for zooplankton -from 9.2 × 10 3 to 19370.0 × 10 3 individuals / m 3 and from 3.8 to 361.7 g / m 3 . Freshwater and euryhaline species were dominant. In polyhaline Lake Zun-Torey, the phytoplankton consisted of 3-12 taxa of algae (total number of taxa -18), and the invertebrate fauna included only 3 species. The abundance of phytoplankton varied from 12.4 × 10 3 to 310.7 × 10 3 cells / L and a biomass from 1.0 to 14.7 mg / m 3 , and the abundance of zooplankton varied from 55.1 × 10 3 to 1656.0 × 10 3 individuals / m 3 and a biomass from 1.1 to 85.5 g / m 3 . Euryhaline and halophilic species dominated.Особенности планктонных сообществ Торейских озер (Забайкальский край) в маловодный год Е.Ю. Афонина, Н.А. Ташлыкова Институт природных ресурсов, экологии и криологии СО РАН Россия, 672014, Чита, ул. Недорезова, 16а Озера Барун-Торей и Зун-Торей являются самыми крупными водоемами в Забайкальском крае, для них характерна хорошо выраженная цикличность, проявляющаяся в многолетних изменениях уровня воды. Материалом для работы послужили пробы, собранные на Торейских озерах в июне, августе, октябре в маловодный 2016 г. Сбор и обработка материалов проводилась согласно стандартным гидробиологическим методам. Целью работы стало изучение особенностей развития планктонных биоценозов Торейских озер, одновременно находящихся в разных гидрологических фазах: Барун-Торей -в начальной фазе наполнения, Зун-Торей -в фазе снижения уровня воды. В районе северной оконечности высохшего Барун-Торея в пределах дна его ложа отмечались мелкие водоемы, источником питания которых служила многолетняя мерзлота и разгрузка подземных вод по разлому, проходящему по западному берегу озера. В Зун-Торее продолжался процесс обмеления водоема, который закончился практически полным его высыханием осенью 2017 г. Состав и структура...
