“…Hydrochemical and hydrophysical analyses were carried out seasonally during 2010-2019 in all the types of water bodies once a season. The data on the content of silicium in Denyshyvske Water Reservoir were kindly provided by the employees of the Department of Freshwater Hydrochemistry of the Institute of Hydrobiology of National Academy of Sciences of Ukraine T. P. Zhezherei, P. M. Linnik, V. A. Zhezherei, to whom the authors are extremely grateful (Linnik et al, 2016). The indication of algal species in relation to the temperature factor was carried out according to (Barinova, 2011).…”

The study is focused on the influence of mechanisms of anthropogenic activity and climate changes of different types and levels on the autotrophic link of freshwater ecosystems. The studies of the river, lake, water reservoir and quarry phytoplankton in the territory of the Ukrainian Polissia were carried out during 2005–2019 according to the standard methods. At the same time, we determined water hydrophysical and hydrochemical characteristics. Exactly 812 algal species represented by 877 infraspecific taxa were identified, including 75 new ones for the Ukrainian Polissia, with a significant share of thermophiles and halophiles. The dominance of Chlorophyta, Bacillariophyta, Euglenozoa and Cyanobacteria was observed in all types of water bodies. With the increase in the nutrient content in the composition of dominant complexes of river ecosystems, the role of centric diatoms Cyclotella meneghiniana, C. stelligera, Stephanodiscus hantzschii increased. The vegetation intensity of Aphanizomenon flos-aquae increased in the water courses with partially regulated flow, while vegetation of Chrysococcus rufescens, Pseudokephyrion pillidium, Kephyrion ovum intensified in rivers with increased colour of water. Water reservoirs are dominated by representatives of Bacillariophyta, Cyanobacteria, Euglenozoa, Miozoa, mostly by Aphanizomenon flos-aquae and Peridinium cinctum. The lowest number of dominant species was identified in the lakes, and belonged to the genera Trachelomonas, Peridinium, Chlamydomonas, Crucigeniella, Cyclotella, Aulacoseira. The dominant species in quarries were Cyclotella meneghiniana, Chlamydomonas monadina, Ch. globosa, Coelastrum microporum, Gomphosphaeria aponina, Trachelomonas volvocina and Microcystis aeruginosa. The obtained data can be used to predict scenarios of changes in the autotrophic link under the influence of natural and anthropogenic factors, to develop methods for monitoring and managing ecosystems at different levels of anthropogenic transformation necessary to ensure an appropriate level of their functions and ecological services.

“…Різноманіття фітопланктону оцінювали за індексом Шеннона (Оdum, 1986). Паралельно з відбором альгологічних проб визначали гідрохімічні й гідрофізичні параметри вод, які були наведені в попередніх публікаціях (Shelyuk, 2000;Linnik at al., 2016). Первинну продукцію фітопланктону й деструкцію органічної речовини визначали кисневою модифікацією склянкового методу на горизонтах 0;10; 0,25; 0,5 і 1,0 м у добовій експозиції (Shelyuk, 2017).…”

Regularities of phytoplankton formation and functioning of small reservoirs are established. Chlorophyta (32.7% of the total list of species) and Bacillariophyta (24.6%) were found to be predominant in species richness. Cyanobacteria species have been found to increase as the area and volume of reservoirs increase, and Euglenozoa is ahead of them in smaller bodies of water. The main abiotic parameters that determine the changes in the structural parameters of phytoplankton of the studied reservoirs are determined. The main differences in the structural and functional characteristics of phytoplankton of small reservoirs built on Polissya rivers in comparison with large Dnieper and Volga ones have been clarified.

The patterns of phytoplankton formation and functioning in small reservoirs of Prypiat and Teteriv rivers basins were studied. Representatives of Chlorophyta species (32.7% of the total number of species) and Bacillariophyta (24.6%) were found to dominate these reservoirs in terms of species richness. It was established that with the increase in the area and volume of reservoirs, the species diversity of Cyanobacteria also increases, while Euglenozoa dominate in smaller reservoirs. The main abiotic parameters that lead to changes in the structural indicators of phytoplankton of the studied reservoirs, as well as the main differences in the structural and functional characteristics of phytoplankton of small reservoirs living in Polissia rivers were studied, in comparison with the large ones of the Dnieper and Volga rivers. A reliable correlation was established between phytoplankton biomass of small reservoirs and pH (r = 0.55), phosphorus content of phosphates (r = 0.46), color (r = -0.36) and total nitrogen content (r = -0.61). Abiotic factors that determine the amount of information diversity in water reservoirs are the phosphorus content of phosphates (r = -0.73), pH (r = 0.63), and watercolor index (r = -0.62). Small reservoirs in comparison with large Dnieper and Volga reservoirs have a high level of photosynthesis intensity with a relatively small biomass of phytoplankton due to their significant optical depth and the peculiarities of the course of production processes of shallow waters, which occupy significant areas of the water areas of small reservoirs.
