Note that some fields concerning aspects of Part 3, the Ecological Character Description of the RIS (tinted in purple), are not expected to be completed as part of a standard RIS, but are included for completeness so as to provide the requested consistency between the RIS and the format of a ‘full’ Ecological Character Description, as adopted in Resolution X.15 (2008). If a Contracting Party does have information available that is relevant to these fields (for example from a national format Ecological Character Description) it may, if it wishes to, include information in these additional fields. 1 - Summary Summary The wetland is situated within the Northern Steppe region of Ukraine along the left bank of the Dnieper River, in the confluence between the Oril and the Dnieper Reservoir. The territory of the wetland is located on a floodplain terrace, which stretches as a strip along the Dnieper River for 16 km from the East to the northern West. The floodplain is a network of wetland types: the mouth of the Oril River, lakes of different origin, marshy aquatic areas and the coastal site of the Dnieper River. Also, there are oakwood areas, floodplain meadows, steppes, natural forests and artificial forest plantations. In general, on the wetland's territory, there have been registered 190 bird species, 10 amphibian species, 6 species of reptiles, 51 fish species and over 20 species of mammals. 134 of the animal species recorded in the site have an international or national protection status Communities of white willow (Saliceta albae), formations of water caltrop (Trapeta natansis) and floating fern (Salvinieta natansis) are typical of the wetland. Within the Site, there are rare species such as sterlet (Acipenser ruthenus), smooth snake (Coronella austriaca), viper (Vipera renardi), black kite (Milvus migrans), northern goshawk (Accipiter gentiles), white-tailed eagle (Haliaetus albicilla), rough-legged buzzard (Buteo lagopus), ferruginous duck (Aythya nyroca). In general, the wetland is the only hiding place of rare animal species in the region during the temporary critical conditions in adjacent territories (hunting, agriculture, recreational burden). The wetland plays a significant role as a place of resting, feeding and breeding for many bird species that have international and national environmental status. The territory is situated on the Dnieper overflight pathway of migratory birds. On the wetland's territory, arround 5 thousand bird individuals nest. During migratory periods; there are 12 thousand aquatic birds. The whole territory of the wetland is part of the Dniprovsko-Orilskyi Nature Reserve.

Pešić: 15 November 2019 │ Published online 3 December 2019. Abstract In December 2016, the common perсarina Percarina demidoffii Nordmann, 1840 has been evidentiary detected in the Dniprovske (Zaporizske) reservoir for the first time. Two specimens of percarina were caught in the rowing channel area (the upper part of the reservoir) near the Dnipro city. One individual was caught there in 2017 as well. The paper presents their morphological characteristics, as well as a comparison with specimens from the brackish waters of the Dniester estuary (the Black Sea). The preliminary data allow us to assume that differences in some plastic characters may have adaptive character in relation to the environment. There are no any meristic differences between these fishes. It is noted that the new finding of this fish species in the cascade of Dniprovske reservoirs allows us consider P. demidoffii as not mesohaline but as a freshwater-oligohaline species. The finding of the common percarina in the Dniprovske reservoir confirms a few earlier published data about the advance of this fish upstream of the Dnieper River and extends its current range.

In the 1970s, six dams were commissioned, and respective monitoring infrastructure was installed. Riverbanks and valley floors composed of unconsolidated material have much lower bank strengths and are susceptible to fluvial erosion and bank collapse, particularly during the release of high flow volumes from hydropower dams. The regulation of the Dnieper River along a cascade of storage reservoirs caused significant changes in its active river channel and hydrological regime. In order to estimate channel stability downstream of the Kaniv reservoir, we conducted an analysis of the hydraulic conditions in terms of changes in flow velocity and propagation of waves caused by intervention water discharges from the Kaniv Hydroelectric Power Plant (HPP).

Box 993, Annandale, New Jersey 08801 YURI PLIGIN Institute of Hydrobiology, Kiev, Ukraine AND BERNIE MAY Genome Variation Analysis Facility, Department of Natural Resources, Fernow Hall, Cornell University, Ithaca, New York 14853 SYNOPSIS. North America’s Great Lakes have recently been invaded by two genetically and morphologically distinct species of Dreissena. The zebra mussel (Dreissena polymorpha) became established in Lake St. Clair of the Laurentian Great Lakes in 1986 and spread throughout eastern North America. The second dreissenid, termed the quagga mussel, has been identified as Dreissena bugensis Andrusov, 1897. The quagga occurs in the Dnieper River drainage of Ukraine and now in the lower Great Lakes of North America. In the Dnieper River, populations of D. poly- morpha have been largely replaced by D. bugensis; anecdotal evidence indicates that similar trends may be occurring in the lower Laurentian Great Lakes. Dreissena bugensis occurs as deep as 130 m in the Great Lakes, but in Ukraine is known from only 0-28 m. Dreissena bugensis is more abundant than D. polymorpha in deeper waters in Dneiper River reservoirs.

The highest flood since the Chernobyl accident took place in River Pripyat in spring 1999. The most contaminated left-side flood-plain upstream the Chernobyl Nuclear Plant has been protected from flooding by a dike constructed in 1992. However right-side flood plain was inundated within a month. Near the Yanov Bay the shallow waste storage sites were inundated. The concentration of 90Sr in the water discharged from this territory to the river has increased to 100000 Bq/m3 at the end of the flooding. The maximum concentration of 90Sr in the river Pripyat the city of Chernobyl was 2000 Bq/m3. The propagation of the sharp pick of radionuclide concentration was monitored in Dnieper reservoir cascade for, approximately, six months. The measured data were processed by statistical methods and were used to develop a scenario for testing radionuclide migration models within the Inco- Copernicus project COMETES. The recommendations for the choice of the size of the computational compartments are suggested accounting for the characteristics of the water bodies. 1. INTRODUCTION The data on the radioactive contamination of the Dnieper River and reservoirs have been used since the Chernobyl accident for the validation of the models of aquatic dispersion of radionuclides.

DIDENKO * Institute of Fisheries of the National Academy of Agrarian Sciences of Ukraine, Kyiv, Ukraine Didenko A.V. 2013. Gobiids of the Dniprodzerzhynsk Reservoir (Dnieper River, Ukraine): distribution and habitat preferences. Acta Ichthyol. Piscat. 43 (4): 257–266. Background. The Dniprodzerzhynsk reservoir is one of six reservoirs built on the Dnieper River, which current - ly supports important commercial and recreational fisheries. To date, there are no published data on the reser - voir’s non-commercial fish species, among which gobies are considered to be the most abundant and important species. The goal of this work was to contribute to general knowledge on local gobiid fauna, focusing on their mesohabitat preferences . Materials and methods. Sampling in the Dniprodzerzhynsk reservoir was conducted during late August of 2011 and 2012 within the framework of routine annual juvenile fish surveys in the Dnieper reservoirs. Fish were col - lected at sampling sites located along the reservoir shoreline using a beach seine made of mill sieving gauze (1 mm mesh size). Mesohabitat features were recorded at each beach seine haul site, and included maximum depth, substrate type, and vegetation density. These data were used to identify fish mesohabitat preferences with the aid of Ivlev’s electivity index . Results. Seven gobiid species were collected: western tubenose goby, Proterorhinus semilunaris (Heckel, 1837); knout goby, Mesogobius batrachocephalus (Pallas, 1814); Pontian monkey goby, Neogobius fluviatilis (Pallas, 1814); round goby, N.

  • Concepts and Records of Range Dynamics in Ground Squirrels and Geographical Barriers in the Pleistocene of the Circum-Black Sea Area
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by UCL Discovery ‘Good fences make good neighbours’: Concepts and records of range dynamics in ground squirrels and geographical barriers in the Pleistocene of the Circum-Black Sea area L.V. Popova, L.C. Maul, V. Zagorodniuk, Yu.M. Veklych, P.S. Shydlovskiy, N.V. Pogodina, K.M. Bondar, T.V. Strukova, S.A. Parfitt Quaternary International 509 (2019) 103–120 Abstract Ground squirrels were an important member of the Pleistocene steppe-tundra mammal community. They evolved ecological specialisations and exhibit behaviours that make them particularly informative subjects to study palaeoenvironmental constraints affecting species distribution and speciation. Interspecific competition and isolating geographical barriers are considered as the principal factors that define species range boundaries. The present paper provides a first comprehensive compilation of the living and extinct Spermophilus species in Europe. These data suggest ‘patchwork quilt’ model for the expansion and spatial distribution of ground squirrel species. Here we consider mainly small-sized Spermophilus species because large-sized (e.g., S. superciliosus) ground squirrels consist another ‘patchwork quilt’, which overlap the first one. This overlapping of the species ranges is possible because of the size difference that lowers interspecific competition (Hutchinson's rule). We consider two main types of range boundaries. One type includes roughly ‘sub-parallel’ boundaries that oscillate in concert with climatic and vegetational changes (a case of climatically controlled competitive exclusion). The other type consists of roughly ‘sub-meridional’ boundaries corresponding to geographical barriers (e.g., water barriers, mountain ridges); these boundaries are rather stable.

    Available online at www.worldnewsnaturalsciences.com WNOFNS 32 (2020) 87-98 EISSN 2543-5426 The zoobenthos structure in the Dniprovske (Zaporizke) reservoir, Ukraine Petrovsky Olexandr, Fedonenko Olena, Marenkov Oleh* Department of General Biology and Aquatic Bioresources, Faculty of Biology and Ecology, Oles Honchar Dnipro National University, 72 Gagarin Avenue, 49010 Dnipro, Ukraine *E-mail address: [email protected] ABSTRACT The article presents data on monitoring the species composition of the zoobenthos of the Dnipro reservoir during 2015-2018. It has been found that a biocenosis of Dreissena (Dreissena bugensis, D polymorpha) was formed on the pass of the upper part of the reservoir on slightly silty sand. The bottom layers of water have been found to be slightly exposed to climatic factors due to slow flow; thus seasonal changes in zoobenthos in the profundal biotope are insignificant. Keywords: Dniprovske reservoir, zoobenthos, species diversity 1. INTRODUCTION Benthos, as defined, are groups of organisms which use the bottom of water bodies as a substrate on which or in which organisms spend their entire life [1]. Zoobenthos is one of the most important elements of the ecosystems of continental reservoirs and watercourses [2]. However, studies on zoobenthos are insufficient. The main reason is its taxonomic composition: representatives of up to twenty classes and ten types are found in freshwater zoobenthos of temperate latitudes [2-4]. Despite the fact that the anthropogenic impact on the Dniprovske reservoir is moderate and the self-purification mechanisms of the reservoir are still in effect, the situation may worsen in the near future, so a comprehensive study on the entire natural complex in the reservoir basin is of urgent importance.

A total of 133 species (138 intraspecific taxa) of Bacillariophyta in the phytoepiphyton of Kyiv, Kaniv, Kremenchuk, Kamianske, Zaporizhzhia, Kahovka reservoirs and in the Lower Dnieper were identified. They belong to 43 genera, 22 families, 13 orders, and 3 classes. Among them, 15 taxa are new records for Ukraine: 14 species and one variety from the genera Achnanthidium Kützing, Amphora Ehrenberg, Cymbella Agardh, Encyonema Kützing, Gomphonema Ehrenberg, Halamphora (P.T.Cleve) Levkov, Navicula Bory, and Nitzschia Hassall. Here we give their brief descriptions illustrated by original microphotographs, synonyms, ecological features, and sampling localities are presented as well. Most of the newly cited Ukraine epiphytic pennate diatoms found on higher aquatic plants are common freshwater taxa. They also include two freshwater-brackish species (Halamphora thermalis (Hustedt) Levkov and Navicula vekhovii Lange-Bertalot et Genkal). Navicula cf. vaneei Lange-Bertalot may occur in the moderately to high mineralized water; Halamphora cf. subholsatica (Krammer) Levkov inhabits mesohaline water bodies.
