“…(Anufriieva et al 2017, Golubkov et al 2018. Similar saline lakes in the Onon-Torey plain in southern Siberia have a salinity range from 1 to 80 g/L, with a sharp decrease in the number of fish and zooplankton species and a gradual decrease of phytoplankton diversity with increasing salinity Tashlykova 2019, Bazarova et al 2019).…”

This review of trends in inland saline lakes of Europe and Central Asia is based on the relevant section of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) Regional Assessment Report for Europe and Central Asia (ECA). We assessed the present status of ECA saline lakes and the effects of direct drivers (climate change, land use, pollution, resource exploitation, invasive species) on ecosystem health and biodiversity. We also assessed past, current and future trends using habitat area and degradation, species richness, and endangered species as indicators. No uniform scenario is applicable to saline lakes in the region. The desiccation of the Aral Sea is caused mainly by land use change and water extraction. In the Caspian Sea, river modifications, water pollution, overfishing and poaching, and species invasions have led to a decrease in species richness and have threatened endemic species. Although trends for smaller saline lakes vary, our analysis demonstrates that land use change, overexploitation, and pollution are more important direct drivers of ecosystem health and biodiversity than climate change. The establishment of baseline biodiversity values for saline lakes is, however, complicated because biodiversity and the food-web structure are variable and depend strongly on salinity. Thus, there is a need to classify the ecological quality, biodiversity and ecosystem services of saline lakes along a salinity gradient. The improvement of water management and reuse of water, conservation measures, and introduction of climate-smart agriculture are basic conditions for the sustainable use of saline lakes in the region.

“…All living communities naturally change their structure, and algae is not an exception (Ansari and Gill 2014;Paulino et al 2018;Bazarova et al 2019). This change is a rather long process, and there is no singular opinion on the reasons for transformations in species structure.…”

Abstract. Kostryukova A, Mashkova I, Belov S, Shchelkanova E, Trofimenko V. 2021. Short Communication: Assessing phytoplankton species structure in trophically different water bodies of South Ural, Russia. Biodiversitas 22: 3530-3538. The study aims to analyze the species structure of the phytoplankton communities of four water bodies in South Ural (Lakes-Turgoyak, Uvildy, Ilmenskoe and Shershnevskoe reservoir). These water bodies are characterized by different trophic states and levels of anthropogenic impact. Lake Turgoyak is oligotrophic; Lake Uvildy is oligomesotrophic. Both water bodies are protected areas and natural monuments. But tourism and recreation are not prohibited on their territories. The mesoeutrophic Lake Ilmenskoe is partially located within the Ilmen State Reserve, and it experiences less anthropogenic impact. The eutrophic Shershnevskoe reservoir is located within the boundaries of the city of Chelyabinsk. It is used as a source of drinking water. Cyanobacteria was the dominant division in the eutrophic Shershnevskoe reservoir. Bacillariophyta dominated in the plankton communities in oligotrophic Lake Turgoyak and oligomesotrophic Lake Uvildy. Green and blue-green algae biodiversity increased in the oligomesotrophic Lake Uvildy. For the mesoeutrophic Lake Ilmenskoe, diatom algae are dominant, but a higher proportion of Chlorophyta (especially Cyanobacteria) was revealed. Species similarity among phytoplankton communities in the given lakes was studied through cluster analysis based on the Sorensen-Czekanowski coefficient. The higher level of similarity between plankton species compositions could be explained by their locality rather than their trophic status.

“…We have been studying the lakes for a number of years, which we have provisionally divided into periods, including three periods for the Lake Zun-Torey (high (1999 and 2003), intermediate (2007,2011) and low (2014 and 2016) lake levels) and two periods for Lake Barun-Torey (high water level (1999 and 2003) and the initial filling phase (2014,2016,2018,2020)). For the majority of the studies (1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016), the methods used are described in detail by Tsybekmitova & Belozertseva (2014), Tsybekmitova (2018), Afonina & Tashlykova (2018, Bazarova et al (2019).…”

This work presents a case study for the lakes Barun-Torey and Zun-Torey, which have been subject to major changes in water level. Both lakes are located in the territory of the Daursky State Nature Biosphere Reserve (arid steppe zone of the Palaearctic region, SouthEast Transbaikalia, Russia), in the border area with Mongolia. The Torey lakes are large and shallow. A unique feature of the Torey lakes is their unstable hydrological regime. The water level variation is explained by the periodic filling and drying of the lakes due to cyclical climatic changes in humidity and temperature. A brief overview of some hydrological and hydrochemical characteristics of the lakes, using references and unpublished (own) data, is provided. The lakes have been studied for a number of years, which have been provisionally divided into some periods.
