The results demonstrated that distribution of values throughout the vegetation season did not correspond to normal distribution, indicating variety of their habitat conditions. The vegetation development in spring was negatively affected by the pyrogenic factor, which formed some areas without vegetation and with poorly developed vegetation. Sharp increase in NDVI values in early summer occurred due to development of wetland ecosystems' edifier Phragmites australis, whose stems emerged from the pickle stage and developed a leaf lamina. In this period, the well-developed vegetation prevailed, its total area exceeded 97%. In autumn, the areas of the developed vegetation gradually decrease, whereas areas of the poorly developed increased. The results of the research showed effectiveness of remote sensing of wetland areas using NDVI and VCI to assess vegetation state; it also can be used for the purposes of the conservation, restoration and sustainable use of wetland ecosystems of the north-west Black Sea coastal area under increasing anthropogenic pressure and global climate change.","PeriodicalId":39692,"journal":{"name":"Hydrobiological Journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67522105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It should be noted that this phenomenon was observed in early summer as well during the period of ichthyoplankton mass development, which is indicative of the sufficient food base. The highest quantitative indices of zooplankton development were registered in multispecies communities of aquatic plants in floodplain water bodies especially under lentic conditions unlike those occurring in mono-species communities of macrophytes observed in the main riverbed of the Desna River, the development of which was limited by high current velocity. Ichthyoplankton was also registered mainly in macrophyte communities.

It was found that the water temperature increase resulted in changes of the metabolic processes, namely decrease of the total protein and glycogen content in gills of Unio tumidus and U. pictorum. Under critical temperatures (30±0.5°C), high activity of LDHase and decrease of K+/Na+-ATPase activity was registered, as well as increase of the filtration rate and oxygen consumption. Considerable need for oxygen was conditioned by oxidation of the energy substrates for instant production of energy for the adaptive processes. However, prolonged impact of increased temperature and thus high rate of metabolic processes in the mollusks can result in exhaustion of the energy resources available for key biological processes, such as growth and reproduction. These results confirmed that over the water temperatures rise owing to the global climate change, many populations of the freshwater bivalves can appear dangerously close to the upper limit of the thermal tolerance.","PeriodicalId":39692,"journal":{"name":"Hydrobiological Journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67522905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Attention is focused on the fact that the fresh waters' salinization inevitably results in decrease of the ecosystem services scope. The main factors and anthropogenic sources of influence on total dissolved solids in the fresh waters and metamorphosis of their ion composition are considered. It is stated that climate changes potentially affect and will affect the surface waters mineralization in future owing to volume and frequency of the atmospheric precipitation, intensity of the rocks and minerals weathering, the ground feeding of the rivers, the marine water penetration into the estuaries along with reducing of the river water yield, etc. The possible impact of mineralization changes on migration of substances from bottom sediments into the water thickness, that is on the intensity of its secondary pollution, is discussed. This impact can be direct and indirect. First of all, it concerns the migration ability of metals in bottom sediments. Elevated content of Na+, Ca2+ and Mg2+ in water intensifies migration of metals of the exchangeable fraction of bottom sediments. The indirect effect of elevated mineralization is expressed in the oxygen regime of the water bodies, which usually deteriorates in the near-bottom water layers of deep lakes and reservoirs, mouth areas of the rivers and estuaries. The dissolved oxygen deficit becomes usual, anoxic conditions are formed, which favor release of Fe(III) and Mn(IV) from oxyhydroxides or the oxide fraction of the bottom sediments. A review also considers some aspects of potential impact of the fresh waters salinization on survival of the aquatic plants and animals and biodiversity.","PeriodicalId":39692,"journal":{"name":"Hydrobiological Journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67523062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been found that the increase in water temperature from 5&deg;C to 15&degC resulted in the increase in the concentration of inorganic nitrogen, inorganic and total phosphorus, and dissolved silicon respectively by a factor of 1.6, 1.1, 1.2, and 1.4. The increase in water temperature from 5&degC to 25&degC resulted in the increase in the content of these nutrients by a factor of 1.8, 5.8, 1.9, and 2.5. Water temperature increase influenced the contribution of nitrogen compounds to the total balance of inorganic nitrogen. A relative content of ammonium decreased, whereas the contribution of nitrite- and nitrate ions increased as a result of the process of nitrification. The concentration of readily oxidized organic matter and the total content of organic matter also increased almost by a factor of 1.6 with increasing water temperature from 5&degC to 25&degC. Under such conditions, the concentration of aluminum, manganese, and chromium increased by a factor of 1.9, 3.2, and 2.0. In this case, the content of iron and copper remained almost unchanged due to their occurrence in inaccessible fractions of bottom sediments. Artificial aeration at 25&degC was responsible for an insignificant decrease in the concentration of inorganic nitrogen, inorganic and total phosphorus, dissolved organic matter, and also of dissolved aluminum, manganese, and chromium. It has been found that water temperature increase results in the migration of the studied chemical compounds from bottom sediments. However, this process is not as intensive as, for example, with a deficiency of dissolved oxygen and a decrease in pH and redox potential in the near-bottom layer of water.","PeriodicalId":39692,"journal":{"name":"Hydrobiological Journal","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135800404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
