The Crimean Peninsula holds a large number of hypersaline water bodies. Our studies focused on these poorly investigated habitats, and included few brackish freshwater ponds. Seventeen species were identified, which only 4(5) collected from waters sometimes with extremely high salinities (Acanthocyclops sp. copepodid, 210 ppt; Eucyclops 150 Diacyclops bisetosus Cyclops furcifer, 140–150 ppt). We also report the occurrence three alien thermophilic (Eucyclops roseus Ishida, 1997, Mesocyclops...
Context Ruppia thickets and their impact on zooplankton in a hypersaline shallow lake. Aims To investigate the long-term dynamics of seagrass Ruppia, abiotic parameters evaluate relationships among them Lake Moynaki. Methods Quantitative assessment thickets, within outside, temperature, salinity, wind speed direction from 2019 to 2023. Key results The first young shoots appeared lake during March, number biomass increased, most rapidly spring. From 2023, average spring gradually increased...
<title>Abstract</title> Saline lakes are hypersensitive to changes in their water balance and therefore show amplified responses climatic land-use catchment. However, despite the resulting, often dramatic ecological consequences, saline rank low on policy agendas as they assumed support few ecosystem services levels of biodiversity. Here, we challenge this view evaluate threatened species 84 distributed across globe. We found that harbour not only aquatic biota but also a diverse range...
All over the world hypersaline lake/lagoons are threatened by climate change. The marine Bakalskoye Lake (Ukraine) was studied in 2000-2012. paper considers changing crustaceans within context of lagoon changes. A sharp drop salinity occurred 2004 due to a changed wind rose because strong winds Western direction began dominate, and as result, washing away spit be more intensive; water inflow into lake increased. structure primary productivity has completely; total production decreased. list...
Chironomidae larvae may represent more than 70% of total Arthropoda numbers in hypersaline waters. Crimea, the largest peninsula Black Sea, has 50 water bodies marine and continental origin. are common components their ecosystems, but they still poorly understood. This paper summarizes results a long-term study (2007–2016) chironomids Crimean More 400 samples from 38 were used for analysis. The maximum salinity containing Сhironomidae was between 320 340 g/L. At first it shown that...
Lakes and lagoons play an important role worldwide, salinity fluctuations significantly affect their ecosystems. Bay Sivash, the world’s largest hypersaline water body, underwent a sharp change in salinity, induced by closing of North Crimean Canal. To monitor shift ecosystem, study was carried out from 2014 to 2020 at 15 sites lagoon. Since closure canal, average increased 22 g L−1 (2013) 94 (2020). Suspended solids dissolved organic matter also increased. When above 50 L−1, number taxa...
Hypersaline habitats are among the most polyextreme on Earth, but they contain a rather large diatom species diversity. A review of species’ richness was made three scales: 1. separate lake in Crimea; 2. all hypersaline waters and 3. world totality as whole. In total, 51 were found Lake Chersonesskoye during sampling from 2004 to 2018. ten Crimean lakes, 91 noted total. All studied water bodies belong 458 species, which is 2.7% total number known Bacillariophyta. scales, similarity...
Biotic changes and a salinity increase (from 13 to 40 g.L-1) occurred in Lake Qarun (Egypt) since 1901. Was increasing cause of observed biotic changes? To answer this question we used benthos as model group. Benthos water sampling was conducted different seasons (2008–2013). Comparing our literature data, discuss the long-term trends possible causes changes. Salinity reached 3 g.L-1 middle 19th century; caused by were started. From century 1928 transformation driven increase; after regular...
Bay Sivash was a hypersaline lagoon but after construction of the North Crimean canal, it shifted to brackish water state. In 2014, canal closed; salinity increase started. 2018 and 2019, plankton sampling conducted in bay at from 30 100 g/L. A decrease taxonomic diversity total abundance observed. Before November 2018, Harpacticoida chironomid larvae were most common abundant groups. Different stages Artemia consumed by invertebrate predators fish that time. contributed more than 90%...
Cladophora spp. constantly or periodically form floating and benthic mats in Crimean hypersaline lakes lagoons. In 2017–2018, characteristics of the microalgae on filaments were studied employing field research microscopy. The whole mat has a vertical structure, including upper lower layers mat. total, 50 species found: 40 them belonged to Bacillariophyta (Bacillariophyceae Mediophyceae), two Haptophyta (Coccolithophyceae), four Miozoa (Dinophyceae), one Chlorophyta (Zygnematophyceae) three...
