The paper considers the present-day taxonomic and ecological diversity, spatial patterns of phytoplankton and algae on the interface of two phases: water – substratum (microphytobenthos and phytoepiphyton) in the most typical biotopes of Kaniv Reservoir in summer seasons of 2017–2022. 301 species (311 intraspecific taxa) of algae have been identified from 142 genera, 75 families, 44 orders, 15 classes and 8 phyla. At the phyla level Bacillariophyta, Chlorophyta and Cyanobacteria dominated. The highest number of species and infraspecific taxa – 143 (146) have been found in microphytobenthos. The highest diversity at the level of genera (98), families (57), orders (37), classes (11) and phyla (7) was observed for the phytoplankton. The phytoplankton was dominated by Chlorophyta and Bacillariophyta, the microphytobenthos and phytoepiphyton – by Bacillariophyta. The highest level of species similarity has been recorded between the algal communities at the interface of two phases: water – substratum, the highest dissimilarity – between phytoplankton and phytoepiphyton. According to geographic distribution cosmopolite species prevail, according to saprobity – χ-ο- and β-mesosaprobic organisms, according to salinity preferences – indifferent species, according to pH preferences – alcalifilic species. According to biotopic preference typically planktonic and eurytopic forms dominate the phytoplankton, and benthic and eurytopic forms dominate the microphytobenthos and phytoepiphyton. Comparing the present-day findings with the retrospective data has not shown any significant changes in the phytoplankton and the microphytobenthos structures. As before, Chlorophyta, Bacillariophyta and, to a lesser extent, Cyanobacteria continue to dominate in phytoplankton, and Bacillariophyta and Chlorophyta – in microphytobenthos. It is explained by natural internal processes prevailing in Kaniv Reservoir, relatively stable level of human impact, and constant algal flow from Kyiv Reservoirs and tributaries. Nowadays phytoplankton, microphytobenthos and phytoepiphyton are distinguished by high taxonomic diversity and play an important role in Kaniv Reservoir biodiversity.

“…Вибір цих чинників середовища пов'язаний із тим, що внаслідок глобальних кліматичних змін відбулися певні зміни середньостатистичної температури повітря та, відповідно, води [16,20]. Також за цих умов змінюється і йонний склад води природних екосистем, у деяких випадках відбувається підвищення мінералізації води через процеси її випаровування або опріснення за надмірних атмосферних опадів [5].…”

При цьому варто відмітити, що за спільного споживання глікогену і білкових субстратів відбувається відновлення рівня глікогену у процесах глюконеогенезу за рахунок збільшення частки використання білка [1, 20,21].

According to observation data obtained at the drinking water intake in the Kamyanske reservoir in the village of Auly, the basic patterns of water blooming were specified. Water abstraction in here is performed from the depth of 8-9 m, which roughly corresponds to a mid-point of the maximum depths. It was determined that the number of algae per unit volume is very large - significantly higher than at the water intake of the Dnieper Water Supply Station (DWSS), which is located in the downstream of the Kyivska HPP. In some cases, it may exceed 1000 million in 1 dm3. During the study period, a decrease in algae amount was recorded, mainly, starting from 2018. The largest algae amount per a volume unit is usually observed in September, i.e. later than in the surface layer of water. The largest algae amount was recorded in September of 2010 and 2014. The factors that contributed to the development of algae at this time are given. Such factors were primarily high air and water temperatures, as well as low cloud cover. There is some delay in changing weather conditions. From June to November, blue-green algae are dominant in the water intake in the village of Auly, the share of which in August-October reaches 95-99%. From December to April, diatomic algae are dominant. The share of green algae is the highest in summer, but it does not usually exceed 2-3% of the total. The significant development of algae in the Kamyanske Reservoir is confirmed by remote sensing data. According to satellite data, it was found out that in this reservoir the largest blooming is observed in the place of water intake location. The dependence of water blooming on hydrometeorological conditions, in particular the direction of wind currents is also shown. The dominance of the northeast wind over the Kamyanske Reservoir in the summer causes a wind setup to the water intake, which results in the increase in the number of algae cells per volume unit.
