“…Changes in physical or chemical parameters can result in an increase or decrease in the abundance and biomass of phytoplankton and zooplankton species. In the Small Aral Sea (Kawabata et al, 1997) and Altai lakes (Vesnina et al, 2012), phytoplankton density decreased with increasing salinity, but no such relationship exists in Lakes Balkhash and Kamyslybas (Kawabata et al, 1997). In the Aral Sea, dinophyte and diatom algae were observed in areas with high TDS values, while blue–green algae were most conspicuous in areas with medium and low TDS values (Kawabata et al, 1997).…”

Aquatic ecosystems in arid regions are important habitats for aquatic wildlife and also support species biodiversity. Soda lakes in endorheic drainage basins, so‐called amplifier lakes, are sentinels of climate change and are of scientific significance. Here we present the results of a long‐term study (20 years) of the Torey lakes, Transbaikalia, Russia, including the period from the maximum capacity of the Torey lakes through to aridification, and then to the initial phase of refilling. Our aim was to determine the response of planktonic communities in the lakes to environmental change over this period. We conducted our studies during various parts of the hydrological cycle, including three phases for Lake Zun‐Torey (high [1999, 2003], intermediate [2007, 2011] and low [2014, 2016] water levels) and two phases for Lake Barun‐Torey (high level [1999, 2003] and the initial refilling phase [2014, 2016, 2018, 2020]). Lake Barun‐Torey dried up completely in summer 2009, and since 2013 has been undergoing initial refilling. Lake Zun‐Torey dried up in the autumn of 2017. Temporal variation in planktonic communities differs for each lake. We identified four stages of changes in the planktonic associations during the aridification of Lake Zun‐Torey (the phytoplankton experienced a decrease in abundance and biomass, and was dominated by green algae and diatoms; the zooplankton underwent a decrease in species diversity and an increase in total abundance and biomass, which were caused by an increase in the abundance of some crustacean species) and three stages of changes as the lake level fell and during the initial refilling of Lake Barun‐Torey (the plankton communities increased in species richness and abundance in the transient pools). These results show the complexity of long‐term community dynamics in arid‐zone soda lakes. They have revealed how phytoplankton and zooplankton community diversity and structure can vary with changing environmental conditions and may pass between distinct states related to the stages of the hydroperiod.

“…Lake Kuchukskoye (Kuchuk) is located on the southern edge of the West Siberian Plain in the closed Ob-Irtysh interfluve. Its water area is 166 km 2 , the average depth -2.3 m (maximum of 3.3 m), and the lake basin area -3240 km 2 . The lake is drainless with inflowing Rivers Kuchuk and Solonovka.…”

“…Despite rather long investigations of zooplankton from lake Kuchukskoye, the dependences of its dynamics on environmental factors were previously studied mainly in the phenomenological aspect. Our goal was to study the composition, structure and dynamics of zooplankton of lake Kuchukskoye influenced by natural factors using the up-to-date computer-based statistics programs [2,10].…”

Seasonal and interannual dynamics of Artemia crustacean population from hypersaline Lake Kuchukskoye (Western Siberia)

The paper presents the findings of studying the influence of main natural environmental factors on interannual (2017–2018, 2020–2021) and seasonal (from April to October) dynamics of Artemia population from large hypersaline lake Kuchukskoye located in the Kulunda steppe (Altai Krai, Russia). We studied the relationship of 7 key indicators of the population structure (abundance, biomass and age structure) with hydrophysical and hydrochemical indixes (temperature, transparency, pH and total salinity). In different years, hydrophysical and hydrochemical regime of lake Kuchukskoye may vary significantly thus affecting brine shrimp population indicators. The revealed changes in the structure of zooplankton are mainly due to the inhibitory effect of increased salinity on the Artemia population and other taxa.

Results of long-term data (2000–2019) on the fertility of female Artemia from different types of hyperhaline reservoirs in the Altai region in the framework of the monitoring is analyzed in this work. A mandatory condition for determining the generative activity of female Artemia on live material has been established. The limits of individual fertility and average fertility are calculated, and the influence of abiotic factors on its volume is shown. The features of changes in the qualitative content of the egg SAC of female Artemia in reservoirs with different levels of water salinity and the course of its change during the period of vegetation are studied. The average number of litters (broods) for Altai populations was calculated, and the influence of environmental factors on this indicator was analyzed.
