“…An intensive consumer of Artemia is also the amphipod G. aequicauda (Shadrin, Yakovenko, et al, ), which was noted in the bay at salinity up to 95 g/L. Some Crimean halotolerant species of Ostracoda, Calanoida and Cyclopoida are also able to consume Artemia nauplii (Anufriieva, Vdodovich, & Shadrin, ; Shadrin, Yakovenko, et al, ). It is impossible to exclude the fact that chironomid larvae B. noctivagus are able to eat Artemia , as a number of chironomid larvae are facultative predators eating plankton crustaceans (Berg, ; Henriques‐Oliveira, Nessimian, & Dorvillé, ; Hildrew, Townsend, & Hasham, ).…”

Bay Sivash was a hypersaline lagoon but after construction of the North Crimean canal, it shifted to a brackish water state. In 2014, the canal was closed; a salinity increase started. In 2018 and 2019, plankton sampling was conducted in the bay at salinity from 30 to 100 g/L. A decrease in taxonomic diversity and total abundance was observed. Before November of 2018, Harpacticoida and chironomid larvae were the most common and abundant groups. Different stages of Artemia were consumed by invertebrate predators and fish at that time. In November 2018, Artemia stages contributed more than 90% to total zooplankton abundance at all sites excepting with salinity lower than 55 g/L. In June–July 2019, adult Artemia were at all sites with salinity higher than 82 g/L when there was no suppression by predators. A self‐sustaining Artemia population in the bay may recover in 2 or 3 years, when the average salinity would reach 80–90 g/L; total abundance of the active Artemia stages may reach 3000–5000 ind. M−3 between April and August. The lagoon may become one of the world main habitats of Artemia having a significant impact to provide world's supply by its cysts.

“…Lake Сhersonesskoye (44°35′10″N, 33°23′32″E) is located on Cape Chersonesus (City Sevastopol; Figure ) and, as a closed marine lagoon, is separated from the sea by a narrow boulder‐pebble spit with filtration of marine water through it. Its area is 0.05 km 2 , the catchment area is 0.92 km 2 , and the average depth is 0.38 m (Anufriieva, Vdodovich, & Shadrin, ). The maximum salinity in the main part of the lake reached 120 g/L in 2005–2018, and up to 340 g/L (August 2009) in the separated southern part.…”

“…In this paper, data from these sample analyses were described from the point of view of the presence and abundance of Artemia and their potential predators. In this paper, the authors also used data from experiments, the technique of which was described earlier (Anufriieva et al, ). Experiments with Artemia eggs, cysts, adults, and nauplii were carried out.…”

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.

“…1D), pero también se conoce en Grecia (Klie, 1941;Fuhrmann, 2012;Rasouli et al, 2016), Bulgaria (Klie, 1937), Ucrania y Georgia (Bronshtein, 1947), la zona europea de Turquía (Altinsaçli, 2001) y, en forma de restos fósiles procedentes de sedimentos holocenos, del hoy desecado Salziger See (literalmente, 'Lago Salado') en el estado de Sajonia-Anhalt, Alemania (Fuhrmann, 2012). Aun cuando se trata de una especie característica de ambientes meso-hipersalinos, se ha comprobado experimentalmente su tolerancia a un amplio rango de salinidades (Santamaría et al, 1992;Mezquita et al, 2001;Anufriieva et al, 2018). Esta circunstancia, que también ha sido observada en algunas comunidades de insectos acuáticos (Arribas et al, 2019), explica que en el presente estudio se haya detectado su presencia en dos humedales de contrastada naturaleza: Rincón del Muerto (humedal meso-hipersalino); y Siles (humedal dulce) (Tabla 2).…”

Se muestran los primeros datos sobre la comunidad de ostrácodos en los humedales del sudeste de España (provincias de Jaén y Córdoba). Se han estudiado un total de 21 humedales, habiéndose registrado la presencia de 12 especies de ostrácodos, pertenecientes a 8 géneros diferentes. Los valores de singularidad muestran la importancia de los humedales temporales y salinos para esta comunidad biótica. Esta aportación pone en valor la necesidad de incrementar el conocimiento que se tiene sobre la distribución y ecología de las especies de ostrácodos en la Península Ibérica.
