“…It has been reported that phytoplankton communities in mountain lakes are mainly related to phosphorus, nitrogen, and silicon contents, with Bacillariophytes predominantly closely related to silicon content and green algae mainly related to salinity (Krupa and Barinova 2015), consistent with the findings of the present study in brackish lakes. In addition, salinity and EC have been noted to strongly affect phytoplankton structure and abundance in the Great Salt Lakes, QTP lakes, and Baltic Sea coastal lakes (Barrett and Belovsky 2020;Krystian 2018;Zhaoxi 2021), which is in agreement with the results of the present study in brackish lakes. Although both brackish and freshwater lakes are affected by PCI such as water temperature and EC, phytoplankton communities as well as their main groups in brackish and freshwater lakes have been observed to show different environmental drivers.…”

Phytoplankton are the main primary producers in aquatic ecosystems and play an important role in food web and geochemical cycles. Its diversity, community structure, and assembly process are influenced by several factors. Among these factors, climate change and human synergistic changes in water physicochemical factors and nutrient levels are the main causes. Alpine lake ecosystems are relatively weak and extremely sensitive to global climate change. However, the impact of climate change on phytoplankton in Qinghai-Tibet Plateau (QTP) lakes and their responses are still unclear. In this study, we systematically analyzed the diversity, environmental drivers, and assembly process of phytoplankton community in the central QTP lakes. The phytoplankton of these lakes can be primarily distinguished into freshwater and brackish types, with significant differences in species diversity and community dissimilarity. Both types shared nearly same key environmental factors that significantly affecting phytoplankton such as EC, and brackish lakes were also positively correlative with TN, Ca and Si. Stochastic process was predominant in phytoplankton assembly because of the harsh environmental condition. Additionally, freshwater and brackish lakes were dominated by dispersal limitation and heterogeneous selection respectively. Alpine lakes had significant EC thresholds, and their diversity and assembly processes changed significantly around the thresholds. Owing to warming and moistening of QTP during the past decades, some significant changes have occurred, such as gradual decrease in lake EC. The present findings have important implications for understanding and predicting the response of lake phytoplankton communities to climate change and for making decisions to protect the ecological resources of alpine lakes.

“…In the Great Salt Lake (U.S.A.), centric and pennate diatoms dominate the phytoplankton assemblage when there are high inflows to the lake and when the salinity ranges from 13% to 15%. Furthermore, even with reduced inflows, salinity continued to decline, and diatoms were replaced by cyanobacteria and green algae, which increased in abundance (Barret & Belovsky, 2020). In Canadian soda lakes, increases in salinity and mean temperature are usually accompanied by a shift away from cyanophyte species, in favour of chlorophytes, cryptophytes, and chrysophytes (Evans & Prepas, 1996).…”

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.

“…However, both a short and long-term perspective of the water level changes must be considered as the relative importance of background climate oscillations in ISL remains uncertain and often masks long-term trends in environmental variables but can be accounted for through more comprehensive statistical analyses [40]. Of course, trophic web changes in relation to the water level fluctuations are essential information to know the full spectrum of biodiversity of ISL [45]. This includes the distribution of habitats and communities on the shores of the lake, which also fluctuate as the water level markedly changes [46].…”

The classical management approach of inland saline lake ecosystems focused on ecological issues, including conserving their biological communities and physical-chemical characteristics. However, the peculiarity of saline lake ecosystems is that they are in a limited watershed, in many cases a closed watershed. So, its management should be planned and performed at watershed scale, which has been frequently neglected. W.D. (Bill) Williams was one of the key persons rising awareness for conservation and promoting their rationale management based on scientific research results. This work shows, through a literature review, that classical management approaches included returning impacted salt lakes to initial conditions through, mostly, eliminating the processes impacting them. At the turn of the century, a wider approach emerged. In addition to focusing on watershed scale management, the integration of social, economic, and environmental issues was incorporated into management proposals by different authors. Lake Gallocanta case study is described and discussed as a paradigm of inland salt lake management. The status of inland salt lakes will improve in the future if land cover reparcelling, and rationale uses of water in the watershed are incorporated, considering adaptive practices to climate change impacts and a balanced provision of ecosystem services.
