The features of the dynamics of nitrogen and phosphorus compounds, the turnover time, and the components of the balance of compounds of biogenic elements in the VL ecosystem, as well as the degree of their temporal variability, have been analyzed. It is shown that the variability of nitrogen and phosphorus compounds in the aquatic environment increases in spring and autumn periods. This is due to an increase in river flow into the lagoon and an increase in the level of external biogenic load on the water area of the VL. Model calculations of matter fluxes allow us to state that the inputs of dissolved organic and suspended matter into the lagoon from external sources and the removal to the Baltic Sea are important processes that significantly affect their content in the VL ecosystem. It has been established that under strong winds the process of sedimentation of suspensions can be largely blocked, and the intensity of BS resuspension can increase significantly. An analysis of the main qualitative and quantitative features of the nature of the temporal dynamics of the DON and DOP turnover times, as well as the mineral compounds of nitrogen and phosphorus, indicates a close conjugation of the processes of transformation of dissolved organic and inorganic substances in the water of the VL. A quantitative assessment of the processes of consumption and excretion of compounds of biogenic elements by different groups of aquatic organisms has been performed, and the important role of heterotrophic bacterioplankton and protozoa in the processes of transformation of compounds of nutrients in the VL ecosystem has been shown. The model can be used for scenario modeling and analyzing possible changes in the VL ecosystem under changing climatic and anthropogenic conditions.</p>","PeriodicalId":50359,"journal":{"name":"Inland Water Biology","volume":"11 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142247750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phenomena such as the disappearance or a sharp decline in the abundance of cold-water species (European smelt, vendace, burbot, and pike) in the Rybinsk Reservoir coincide with the period of warming. The disappearance of European smelt in the Rybinsk Reservoir and the favorable temperature regime has contributed to the appearance and rapid increase in the abundance of a Caspian invader, the Black Sea sprat, which has occupied the empty niche of the European smelt and became the dominant species in the pelagic zone of the Upper Volga reservoirs. Warming has resulted in a decrease in the abundance and the growth rate of burbot and pike.

One-time intensive sampling (20 quadrates per station) was performed in the dry-period. The benthic macroinvertebrate samples were collected to all possible current velocities at each station from 7 cm to 55 cm depth. and they were categorized in to 5 categories of current velocity; extreme low (type I, 0–15 cm s^–1), low (type II, 15–30 cm s^–1), mild (type III, 30–45 cm s^–1), moderate (type IV, 45–60 cm s^–1) and high (type V, &gt;60 cm s^–1).

The data obtained during the study of the health of ecosystems of several recreational areas of the Black Sea, the eastern part of the Gulf of Finland, several channels of the Volga delta are considered. An operational assessment of the health of ecosystems was carried out using innovative biomonitoring technology by testing the health of adult bivalve mollusks living in them by the functional load method based on the analysis of their heart rate, measured using the BioArgus bioelectronic fiber-optic system. It has been established that the functional state of mollusks can serve as an indicator of excess pollution of coastal waters by objects that discharge insufficiently treated domestic wastewater from their local treatment facilities, including household wastewater. It is concluded that, taking into account the rather high rapidity and ease of use, this technology can be effectively used to solve the problems of screening studies and early diagnostics of the state of aquatic ecosystems as well as serve as an information basis for developing regionally oriented, science-based environmental management decisions. Recently, the BioArgus automated system was metrologically type-certified (Order of Rosstandart No. 2702 dated 10/27/2022 on the approval of types of measuring instruments).
