SPECIES COMPOSITION OF MACROPHYTES AND ICHTHYOFAUNA OF LAKE MARTYSHIV (KYIV, OSOKORKY) AS IMPORTANT ELEMENT OF THE INTACT FLOODPLAIN COMPLEXES

The article examines the species composition of macrophytes (higher aquatic plants) and ichthyofauna of Lake Martyshiv (waterbody of the Osokorky floodplain, eco-corridor of Kyiv). The features of the ecological distribution of higher aquatic plants within the lake Martyshiv are analyzed. The macrophytes are represented by typical limnophilous(lacustrine) complexes. The presence of various groups of macrophytes in the lake indicates a low level of anthropogenic load and is not so differentfrom the values characteristic of a surface water filesunder standard conditions. 22 species of higher aquatic plants have been registered. Phragmites australis (Cav.) Trin. ex Steud., Typha angustifolia L. and Typha latifolia Lare the most common swamping indicator species. Among the studied plants, it should be noted Nuphar lutea (L.) Smith which is protected on the territory of Kyiv in accordance with the decision of the Kyiv Council of December 23, 2004 No. 880/2290. In the ichthyofauna of Lake Martyshiv, 30 species of fish that belong to 9 familieswere identified. In the structure of ichthyocenosis, phytophils (50%) and zoobenthophages (50%) were the dominant ecological groups in terms ofthe method of oviposition and the type of nutrition, respectively. According to the habitat in the reservoir, bottomfishand thicket-livingcategories prevailed (43.3 and 33.3%, respectively). Four species were found in the ichthyofauna of the lake (Rhodeus amarus (Bloch, 1782), Cobitis taenia (sl) Linnaeus, 1758, Misgurnus fossilis (Linnaeus, 1758), Aspius aspius Linnaeus, 1758), which are included to the listof Resolution of the 6thBerne Conventionthat wasadopted to create the Emerald Network. In addition, Carassius carassius Linnaeus, 1758, listed in the Red Book of Ukraine, as well as the elmLeuciscus idus Linnaeus, 1758, which was included in the new edition of the Red Book of Ukraine, were discovered.The research results illustrate preliminary data on the current distribution of species and biological diversity of aquatic ecosystems of the Osokorkyfloodplain. The presence of a number of ecological groups of macrophytes creates a number of biotopes that are important for the existence and reproduction of fish. Thepreservation of LakeMartyshiv in a lesstransformed state providesgroundsforthe creation of a landscape reserve of local importance.Key words:Lake Martyshiv, macrophytes, ichthyofauna, biodiversity, environmental transformation, habitat. У статті розглянуто видовий склад макрофітів (вищі водяні рослини) та іхтіофауни оз. Мартишів (водойма Осокорківської заплави, екокоридору м. Києва). Проаналізовано особливості екологічного розподілу вищих водяних рослин у межах оз. Мартишів. Макрофіти представлені типовими лімнофільними (озерними) комплексами. Наявність різних груп макрофітів у межах озера вказує на низький рівень антропогенного навантаження та мало відрізняється від значень, характерних для масиву поверхневих вод у референційних умовах.Відзначено 22 види вищих водяних рослин. Найпоширеніші види-індикатори процесів заболочення: Phragmitesaustralis(Cav.)Trin. exSteud., Typha angustifolia L. та Typha latifolia L. Серед досліджуваних рослин варто виокремити глечики жовті Nuphar lutea(L.) Smith,які натериторії Києва охороняються на підставі рішенняКиївської міської ради від 23.12.2004 року No880/2290.У складі іхтіофауни оз. Мартишів виявлено 30 видів риб, які належали до 9 родин. У структурі іхтіоценозу за домінуючими екологічними групами за способомвідкладання ікри та типом живлення були фітофіли (50%) та зообентофаги (50%) відповідно. За середовищем існування у водоймі домінували риби придонних та заростевих груп (43,3 та 33,3% відповідно). В іхтіофауні озера було виявлено 4 види (Rhodeus amarus (Bloch, 1782), Cobitis taenia (s.l.) Linnaeus, 1758, Misgurnus fossilis (Linnaeus, 1758), AspiusaspiusLinnaeus, 1758.), які включені до списку Резолюції 6 Бернської конвенції, прийнятої для створення Смарагдової мережі. Крім того, був виявлений CarassiuscarassiusLinnaeus, 1758., що включений до Червоної книги України, а також в’язь Leuciscus idus Linnaeus, 1758, якого буде внесено до нового видання Червоної книги України.Результати досліджень ілюструють попередні дані щодо сучасного розподілу видів та біологічного різноманіття водних екосистем Осокорківської заплави. Наявність низки екологічних груп макрофітів створює низку оселищ, важливих для існування та розмноження риб. Збереження оз. Мартишів у мало трансформованому стані дає підстави для створення ландшафтного заказника.Ключові слова:озеро Мартишів, макрофіти, іхтіофауна, біорізноманіття, трансформація середовища, середовище існування.

This paper provides an overview of the biology and species diversity of xylotrophic basidiomycetes, as well as the biotopic relationships of xylotroph mycobiota with phytocenoses. Ecological groups of these organisms are considered in connection with substrate specialization and their species similarity in birch and aspen small-leaved forests of different pharmacy. A brief assessment of the influence of the anthropogenic factor on the biological diversity of the represented group of organisms is given. For the first time, the Kostroma region is divided into southern, central, and northern parts to assess species diversity depending on weather, climate, and phytocenotic factors. The data on the study of changes in the degree of integration of mycocenoses of birch and aspen forests within the studied areas of the region are presented. In total, over 60 species of xylotrophic basidiomycetes were found in the small-leaved forests in the region, among which 38 species primarily affected birch forests and 40 species of pathogenic xylotrophic basidiomycetes have tropism for P. tremula. It was established that species belonging to the Coriolaseae family predominate in the species composition of wood-destroying mycobiota; they comprise about 27% of the total species composition in birch forests and about 24% of the species composition in aspen forests.

The spatial and species features of heavy metals (Ti, V, Cr, Mn, Ni, Cu, Zn, Zr, Mo, Pb) contents in higher aquatic plants of reservoirs and rivers within Belarus have been analyzed on monitoring data. The group of submerged plants are characterized by high ash content; and they accumulate large amounts of Ti, Mn, Cu, Zn, Zr, Pb. There are statistically signi ficant differences between the plants in ecological groups of reservoirs and rivers in terms of Mn, Cu, Pb contents in the tissues (elements with a 100 % frequency). According to the spatial analysis the reservoirs of the northern geochemical province account for 71 % of the Mn anomalies and 80 % of the Cu anomalies, including the Braslav region – 46 % of the Mn anomalies and 59 % of Cu. Mn, Cu, Pb maximum concentrations are characteristics of submerged macrophytes such lakes as Snudy, Losvido, Maloye Beloye, Beloye (Luninets District), Beloe (Surmino), Svityaz. Among submerged macrophytes within lakes the abnormal accumulation of Mn has been noted for Charophyta (61 % of cases), Myriophyllum and Ceratophyllum, Cu – Charophyta, Isoetes and Lobelia dortmanna, Pb – Isoetes, Charophyta and Potamogeton. The macrophytes within rivers are characterized by the higher ash content and the average content of Mn, Cu and Pb in comparison with the lakes plants. Areas with identified Cu and Pb anomalies in the submerged plants are confined to the central geochemical province of Belarus (the Svisloch river accounts for 67 % of anomalous values of Cu and 33 % of Pb). Anomalous values of Cu have been fixed in the tissues of the Ceratophyllum and Potamogeton, Pb – mostly in Potamogeton. The cluster analysis has distinguished a group of plant species as a part of the following genera: Potamogeton, Myriophyllum, Elodea, Ceratophyllum and Sparganium. The group is characterized by elevated contents of Ti, V, Cr, Mn, Ni, Cu, Zn, Zr, Pb and recommended as indicators of polluting water objects with heavy metals.

Ecological Forms

The influence of different species and ecological forms of higher aquatic plants on the abundance, biomass and species diversity of zooplankton was investigated in experimental ecosystems (microcosms). It was shown that in the absence of fish and macroinvertebrate predators, the abundance and diversity of zooplankton in the plants beds increased. Not only phytophilous, littoral, and small planktonic crustaceans, but also some large obligate planktonic crustaceans, reached a high abundance among the plants. Plants belonging to different ecological groups stimulated an increase in the abundance of different groups of zooplankton. In the beds of submerged plants, the number of Cladocera increased to a greater extent than Copepoda or Rotifera. The abundance of Copepoda, both Cyclopoida and Calanoida, grew in the beds of helophytes. The relative number of predators in the community increased among the plants. The species structure and quantitative parameters of zooplankton had their own characteristics in monospecies and mixed phytocenoses of the same plant species. The index of species diversity of zooplankton acquired the highest values in the mixed phytocenosis. Higher aquatic plants increase spatial heterogeneity, which stimulates the development of facultative planktonic and benthic species. The formation of phytogenic detritus and the lifetime release of organic substances by plants into the water causes the development of bacteria and protozoa, which expands the quality and size range of food organisms for zooplankton. Therefore, zooplankton becomes more diverse in terms of the set of trophic groups.

The aim of the study was to conduct an environmental evaluation of 6 selected sections of the improved Mietiułka River, which included an inventory and analysis of the vascular flora associated directly with this watercourse. The results of the study have shown that the flora of the study area is diverse in taxonomic, syntaxonomic and ecological terms, and that it comprises both typical aquatic plants and species characteristic of the habitats surrounding the river. In the flora found in the study sectors, a total of 114 vascular plant species was identified, which come from 42 botanical families, 15 syntaxonomic classes and belong to different ecological groups. Hemicryptophytes, spontaneophytes, species neutral to continentality as well as species included in the phytochorion with boreal elements: Euro-Siberian subelement, were clearly predominant in the species composition of the flora of all the study sectors. The macrophytes commonly found in Poland had the largest proportion. One species with a small number of stands in the country - water dropwort (Oenanthe fistulosa) - as well as two species threatened with extinction, Sagittaria sagittifolia and Hypochoeris glabra, were recorded.

Anthropogenic impact on the population of ground beetles leads to a change in their numbers, structure of dominance, density, species composition, spectrum of life forms. This makes the beetles Carabidae a convenient and informative bioindicator of the ecological state of biocenoses. The material for this work was the Carabidae collections conducted in June-August 2016-2017 in the park zone of different regions of Barnaul, differing in location, area, hydrological regime, vegetation cover, purpose and anthropogenic load. When processing the material, the quantitative, species and generic composition of the carabidae was determined, calculations were made for such indicators as the Berger-Parker dominance index, the Shannon species diversity index (Hs), and the Jacquard species similarity index. The fauna (Coleoptera, Carabidae) of the park zone of Barnaul is represented by 55 species belonging to 20 genera. The dominant group is represented by species belonging to steppe, forest and polyzonal groups. Forest-steppe species of ground beetles as dominants have not been identified in any of the investigated territories. The greatest variety of ecological groups was noted on the territory of the Yubileyny рark, which is explained by the presence of zones with various microclimatic conditions, the presence of a birch grove that flows through the park with the Pivovarka River, and a wide log in the park. Registered species belong to eight groups of life forms belonging to two classes - zoophagous and myxophytophagous. On the numerical and species abundance, zoophages predominate. The spectrum of life forms corresponds to the zonal spectrum characteristic of the forest-steppe zone.
