“…Ecosystems of hypersaline water bodies, one of the most extreme habitats on the planet, are unique in many respects (Golubkov, Shadrin, Golubkov, Balushkina, & Litvinchuk, ; Por, ; Williams, ). Only a few species of animals are able to exist in such conditions (Anufriieva, ; Balushkina, Golubkov, Golubkov, Litvinchuk, & Shadrin, ; Por, ; Shadrin, Anufriieva, Belyakov, & Bazhora, ; Timms, ; Williams, ).…”

Artemia spp. play a key role in hypersaline ecosystems. Artemia can live in a salinity range from 10 to 300-340 g/L, but in water bodies where salinity is between 10 and 100 g/L, it may be absent. Is the absence of Artemia in some Crimean lakes determined by the presence of predators or by salinity? To answer this question field long-term and experimental data collected in the Crimean lakes were used. With the least probability, the populations of Artemia existed in the lakes with a salinity of up to 50 g/L or above 300 g/L. Self-reproducing Artemia populations (all age stages) were most likely (≥80% of occurrence) noted in the salinity range of 150-200 g/L. Longterm monitoring in two lakes showed that in different years, a significant negative correlation of Artemia abundance with the numbers of amphipod Gammarus aequicauda and ostracod Eucypris mareotica was found in both lakes. This correlation can be explained by ostracod and amphipod predation on Artemia. In years without predator populations, the number of Artemia was higher by several times.Experiments showed that these amphipods and ostracods consume brine shrimps of different developmental stages. There are at least 12 crustacean species, 5 insect species, and 2 fish species, all listed in this paper, which inhabit Crimean hypersaline waters and can eat Artemia. Their predation on Artemia often is a main cause of its absence in the salinity range from 10 to 150 g/L.

“…However, the Great Salt Lake and many other saline lakes around the world are under threat by climatic oscillations, and brine diversion that impacts salinity and reduces lakes size (Wurtsbaugh et al, 2017), affecting their ecosystem structure and functioning (Golubkov, Shadrin, Golubkov, Balushkina, & Litvinchuk, 2018). This article expresses concern on the fragility of high-altitude hypersaline lagoons in the Atacama Desert due to hyper dryness of the Desert, that could get worse, water shortage due to low rainfall and mining activities (including cooper companies in the area) and the huge volume of brine diverted for lithium exploitation.…”

“…Since biodiversity declines as salinity increases, hypersaline lagoons are relatively low-diversity ecosystems with simple food webs [9] and hence are considered suitable natural laboratories [10] to address fundamental questions of biology. Due to the multiple stressors shaping such unique biodiversity and the potent mutagenic role variation in ionic strength has on DNA-protein interactions, and protein structure, the biodiversity of these lagoons exhibits an accelerated rate of evolution, at least as demonstrated for brine shrimps (Artemia) [11].…”

“…Hypersaline lakes and lagoons around the world are, however, shrinking at an alarming rate due to climate oscillations and water or brine diversion for mining [19]; hence, there is a need to conserve their unique biodiversity, properties, and services to comply with international treaties on biodiversity, ecosystem, and wetland conservation. The lack of systematic and long-term spatial and temporal studies on most hypersaline ecosystems that are often in remote places and tend to exhibit high seasonal variation in their biodiversity [9] makes difficult to understand or predict how they will respond to climate oscillations and increased anthropic pressures.…”

Hypersaline lagoons distributed in arid and semiarid regions are unique ecosystems with unique value stemming from their extremophile biodiversity, limnological properties and services, like mining and waterbird habitat. They are natural laboratories to understand how life evolved in extreme environments and how simple ecosystems function to provide waterbird habitat, an essential noneconomic service. Policymakers need this knowledge to protect these ecosystems increasingly affected by climatic change and human-driven perturbations. Hypersaline lagoons from contrasting latitudinal conditions in Chile provide a study case to evaluate how such conditions affect their microscopic and macroscopic diversities. Those in the hyperarid Atacama Desert in northern Chile are an integral part of mineral-rich salars, whereas Patagonian lagoons are unique among freshwater lakes of glacier origin. Despite latitudinal differences, prokaryotic diversity tends to be similar in both extremes. However, genetically distant brine shrimp (Artemia) species, A. franciscana (north) and A. persimilis (Patagonia), inhabit them. This crustacean is a keystone taxon in the food web, and its abundance indicates ecosystem quality and attracts waterbirds. This chapter stresses the need to systematically monitoring Artemia abundance and all factors affecting its fitness (gut microbiota, parasites, environmental conditions). Finally, the need to conserve these unique and extreme ecosystems is highlighted.
