In recent decades, the influence of anthropogenic impact on aquatic ecosystems has increased. This has led to a restructuring of aquatic ecosystems and affected the structural and functional organization of groups of aquatic organisms, causing qualitative and quantitative changes. Particular attention is drawn to the different types of water bodies of protected areas like Ichnyansky National Park, which is located in Ichnyansky district of Chernihiv region. This park is a newly created one, so the reduction in intensity of anthropogenic pressure can be traced within its waters. Zooplankton plays an important role in the functioning of trophic networks because it transfers energy from producers and primary consumers to young fish and planktonophagous fish. Therefore, three main groups of zooplankton were chosen as the object of study: rotifers (class Eurotatoria), cladocerans (class Branchiopoda, order Cladocera), different age stages of copepods (class Copepoda), and also ostracods (Class Ostracoda). The zooplankton used as research material was collected in the daytime in spring (April), summer (late July-early August) and autumn (late Septemberearly October) in the years 2015-2016 from ten experimental stations. During this period 81 species of zooplankton were recorded within heterogeneous reservoirs of Ichniansky National Park. Monogonont rotifers (subclass Monogononta) included 35 species (43% of all species) and bdelloid rotifers (subclass Bdelloidea), cladocerns, comprised 28 species (35%), and copepods included 18 species (22%). The faunal range of zooplankton over different years and seasons was characterized by the predominance of the rotator complex in spring, rotator-cladocerans and cladocerans in summer, and of the cladocerans complex in autumn. This was due to the formation during spring and summer of favourable conditions in the waters for filter feeders, which consist generally of rotifers and cladocerans. In autumn the water released large amounts of organic matter that caused a reduction in the species diversity of rotifers. Zooplankton also is characterized by the considerable ecological diversity. The range of environmental groups of zooplankton over two years was characterized by a predominance of the pelagic and benthic group of phytophiles. Pelagic representatives included 35 (43%) of 81 species, the bottom group-20 (25%), phytophiles-26 (32%). Rotifers dominated in the pelagic group-18 (51%) species out of 35, and cladocerans-among the bottom group-10 (50%) species out of 20. Zooplankton species also are distinguished by their feeding type. They represented three trophic groups: peaceful-64 (79%) out of 81 species, omnivorous-6 (7%) and predators-11 (14%). Quantitative indicators of zooplankton at most stations in different seasons were defined as "very low" (less than 5,000 ind./m 3 and less than 0.3 g/m 3), "low" (5,000-50,000 ind./m 3 and 0.3-1.0 g/m 3), "below average" (5,000-50,000 ind./m 3 and 0.3-1.0 g/m 3) rates, occasionally-"average" (51-250,000 ind./m 3 and 1.1-5.0 g/m 3), "medi...

Seasonal dynamics of the littoral zooplankton groups of the Uday River within the National Nature Park "Pyryatynsky"

The increase in anthropogenic impact on aquatic ecosystems causes significant alterations in the composition and structure of hydrobiont groups. These processes are characteristic of the hydrobiocenoses of the Uday River, the valley of which lies within the National Nature Park "Pyryatynsky", established in 2009 in the Pyryatyn district of Poltava region. Within this protected area it is convenient to carry out continuous monitoring of changes in anthropogenic load on shore ecosystems of the river. One of the most convenient monitoring groups is zooplankton, which is one of the essential components of the trophic networks of aquatic ecosystems and which is the feeding basis of planktonophagous and young fish. The object of this research was the major groups of zooplankton: rotifers (class Eurotatoria), cladocerans (class Branchiopoda, order Cladocera), different age stages of copepods (class Copepoda), ostracods (class Ostracoda). Zooplankton were collected in the daytime in spring (mid April), summer (end of July) and autumn (late September) 2016 within eight research stations. As a result of the conducted research, 69 species of zooplankton were registered within the littoral water area of the Uday River. Monogonont rotifers numbered 19 (27.5%) species, bdelloid rotifers (subclass Bdelloidea), cladocerans-33 (47.9%) species, copepods-17 (24.6%). According to the faunal spectrum in the zooplankton groups, representatives of the cladoceran complex predominated. This is due to the favourable conditions for the development of filtrators, of which a considerable part is cladocerans. Three species of rotifers were identified in Poltava region for the first time: Beauchampiella eudactylota (Gosse, 1886), Dipleuchlanis propatula (Gosse, 1886), Mytilina acanthophora (Hauer, 1938). During the spring, 33 species of zooplankton were collected: rotifers-10 species, cladocerans-14, copepods-9 species. In summer 41 species were registered, including rotifers-10, cladocerans-18, and copepods-13. In autumn 37 species were found: 6 species of rotifers, cladocerans-21 and copepods-10. The species composition of the zooplankton in different seasons had a low similarity, as evidenced by Jaccard index: spring and autumn (J = 25,4), spring and autumn (J = 34,5), and summer and autumn (J = 34,6). In the spring, pelagic (36.3%) and phytophilic (45.6%) groups prevailed, and phytophilic dominated in summer (41.4%) and autumn (48.7%). Of the various groups classified according to feeding type, representatives of the peaceful group dominated in all the studied seasons, in spring comprising 69.7%, in summer-65.8%, and in autumn-73%. The density and biomass of zooplankton of the Uday River were "low" in spring and summer, and "very low"-in autumn.

“…Zooplankton is one of the most dynamic components of aquatic biota, sensitive to the impact of natural and anthropogenic factors. Th e ecological indices of zooplankton communities (diversity, the abundance ratio of certain taxonomic groups and species, quantitative indicators, saprobity characteristics of edifi cator species) are used to assess the ecological status of aquatic ecosystems and to monitor the quality of the aquatic environment (Pashkova, 2013). Th e zooplankters are hosts of a number of symbionts, with highly varying relationships depending on the localization (epi-and endobiosis) and the peculiarities of metabolic interactions (commensalism, parasitism, etc.…”

In several water bodies of the Dnipro river Basin, parasitological studies of the representatives of main taxonomic groups of freshwater zooplankton (Rotifera, Copepoda and Cladocera) were conducted. Altogether 22 species of different taxonomic groups (bacteria, flagellates, algae, fungi, ciliates, etc.) of symbionts of zooplankters were found. The dataon the symbiofauna of zooplankters and on the aspects of biology of certain epibiotic and parasitic species were summarized. The study showed the peculiarities of symbionts distribution by host species in different taxonomic groups of zooplankton. The number of symbiotic species increased in following order: Rotifera → Cladocera → Copepoda. Copepoda had high species richness of epibiotic ciliates and the highest rates of colonization by epibiotic algae.
