The article presents the history of research of the left tributaries of the Middle Dnieper. The periodization of research by chronological periods from the IV century is developed. B.C. until the end of the XVIII century. The periods and key stages of river research during the corresponding period are highlighted. The issues of description of the respective rivers in antiquity and the Middle Ages are covered, in particular the elements of the geographical position of their river systems, water regime, feeding conditions, economical use, elements of river valleys and the organic world of their basins. Chronicle data and original works of scientists and politicians of these time periods are processed. The issues of geographical position of the river network, number and names of rivers of the studied sub-basin of the Middle Dnieper according to the maps of the XVI-XVIII centuries are covered in detail. Cartographic works of cartographers from France, the Netherlands, Italy, and Muscovy have been studied. Particular attention is paid to the cartographic works of the French cartographer Guillaume Levasser de Beauplan, who began a new stage in the mapping of the main left tributaries of the Middle Dnieper and their smaller tributaries. For the first time, 137 rivers of the Left Bank of the Middle Dnieper were marked on his maps. He put forward the theory of the formation of the channels of the left tributaries of the Middle Dnieper. On the maps of 1680 – 1760, we notice the beginning of the stage of stagnation in the image of the hydrographic grid of the left tributaries of the Middle Dnieper. The information according to the descriptive data of the Left Bank of Ukraine of the end of the XVIII century is singled out. The first detailed descriptions of the rivers – Kyiv, Chernihiv, Kharkiv governorates and Little Russia Governorate in the period from 1775 to 1800 were developed. A complete catalog of rivers of the I, II, III and IV order of the Middle Dnieper sub-basin according to descriptive data within the river basins with indication of their length is given.

The article presents the history of the studies of the left tributaries of the Middle Dnieper. Periodization of the researches by chronological periods from the XIXth century to the beginning of the XXIth century is developed. The author singles out 5 periods and the key stages of the river research during the corresponding period. Further continuation in time of the period of systematization of reliable information about the left tributaries of the Middle Dnieper in 1801-1820s is substantiated. Attention is paid to the described and cartographic data of this period, in particular to the “Detailed map of the Russian Empire and adjacent foreign possessions” for 1801-1804 and “Carte de la Russie Europeenne en LXXVII feuilles executee au Depot general de la Guerre” for 1812. Theories of the XIX – early XX centuries on the formation of the river valleys of the left tributaries of the Middle Dnieper are covered in detail – in the works of Nikolai Arendarenko, Nikolai Markevich, Vasily Dokuchaev, Ivan Levakovsky, Nikolai Maximovich and Eugene Oppokov. Emphasis is placed on two main cartographic works of 1840-1860, reflecting detailed hydrographic network of rivers in the region – the map by N. Arendarenko “The main rivers and ravines of Poltava province” in 1848 and “Military-topographic map of the Russian Empire” 1846-1863 years, by F. Schubert and P.A. Tuchkov. It was highlighted information about the formation of gauging system on the rivers of the left bank of the Middle Dnieper and substantiated the key stages of formation, expansion and curtailment of the gauging system from 1880 to 2012. Information about field scientific expeditions along the rivers of the study region under the leadership of hydrologists V. Lokhtin (1882 – 1892) and E. Oppokov (1894 – 1898). Information is provided on the most accurate catalog of rivers and streams of the Dnieper basin by P.L. Mashtakov, “The List of Rivers of the Dnieper Basin. With Map and Alphabetical Index.” This catalog identifies 9 large basins of the Left Bank of the Middle Dnieper, which lists 569 rivers within the study area. Spatial and temporal analysis of water management, rail transport, agriculture on the main left tributaries of the Middle Dnieper during 1910 – 1930s is carried out. Activities of Hydrometeorological Service of USSR on making hydrological descriptions of the left tributaries of the Middle Dnieper from 1949 to 1960 are covered in detail. A detailed analysis of the list of works on hydrological and other researches concerning the rivers of the left bank of the Middle Dnieper basin from 1920 to 2022 is carried out

Full textAbstract:
The current scope of knowledge of individual fragments of the Dniester valley was analyzed, and it was found thatits pre-Carpathian part remains the least studied. The diagrams illustrating the idea of the structure and history of the formation of this river valleyfragment are mainly based on the diagram by I. Hofshtein developed in the 1960–1970s and coincide with it in terms of boththe number of terraces discovered here and the determination of their age. In recent years, significant progress has been made in the study of the pre-Carpathian fragment of the river valley, in particular in the study of the ancient terraces of the Dniester River, which until now have been "hidden" in the leveling surfaces of Loyeva and Krasna. Low-Upper Pleistocene terraces, which are spread mainly within the borders of the Upper Dniester, Stryi-Zhydachiv, Halytsia-Bukachiv basins and within the 5–10-kilometer sections of the Dniester valley and the valleys of its separate Carpathian tributaries located at the foot of the Carpathian escarpment, remain less studied. Until recently, the youngest of the Pleistocene terraces of the Dniester River was considered to be the Kolodiyiv terrace, the loose accumulations of which are based on alluvium of the Horohiv (Prylutskyi) period. Below it, the first supraflood terrace of Late Pleistocene-Holocene age is developed. On the basis of the analysis of the morphological parameters of the terrace developed within the Halytsia-Bukachiv basin, the analysis of the cross-section of its loose accumulations, a terrace was identified that corresponds to the second supraflood terrace of the Vytachiv-Buzka period, developed in Middle Transnistria. As a result of the identification of the terrace, which we consider as the second supraflood, as well as the terraces discovered within the distribution of the Loyeva and Krasnaya leveling surfaces, the total number of terraces developed in the pre-Carpathian part of the valleys and the Dniester reached twelve: the late Pleistocene-Holocene first floodplain terrace; late Pleistocene second (Tustan) and third (Kolodiiv) floodplain terraces; Middle Pleistocene fourth (Jezupil) and fifth (Maryyampil) floodplain terraces; early Pleistocene sixth (Halytsky), seventh (Biskovytsky), eighth (Susidovytsky), ninth (Dubrivsky), and tenth (Torganovytsky) supraflood terraces; Pliocene (?) eleventh (Starosilska) and twelfth (Krasnianska) supraflood terraces. Key words: terrace; morphology; Dniester valley; loess; alluvium; stratigraphic horizons.

Full textAbstract:
S. Rudnitsky’s research continued in Podillya; he went on studying the morphology of genesis and history of the relief of the Carpathian and pre-Carpathian Dniester basins. Many years of expeditionary research (1903-1912) resulted in the monograph “Prerequisites for Studying Morphology of the Podilsky Catchment Area of the Dniester”, which was recommended for publication at the meeting of the Mathematical & Nature Descriptive section of the Shevchenko Scientific society (NTSh) on April 17, 1912. This work provides detailed morphographic and morphometric characteristics of the Galician Podillya relief. The monograph also reports on the formation of the Dniester basin river system, geological structure, paleogeomorphology, as well as morphological & genetic problems. In studying the Podilsky Dniester Basin, S. Rudnytsky made numerous conclusions on the problems of morphological regionalization, the relief history, in particular the formation of the Dniester valley and its Podilsky tributaries, which have not lost their relevance to this day. We can distinguish the following major points among the main findings of S. Rudnitsky's research of morphogenesis and the evolution of the Podilsky Dniester basin relief: (1) Geomorphological division of the Galician Podillya with districts allocation: Roztochya, Vereshchytsky-Shchyrets lowland, Mykolayiv-Bobretskyi “horbovyna” (land surface with hills) (Pidopillya), Opilsky “horbovyna”, Podnistriya, Podillya and Gogoloro-Kremenetsk Ridge; (2) Clarification of the history of individual regions development: the erratic Scandinavian material in Roztochya is mixed (Scandinavian-Carpathian); it is deposited by fluvia-glacial flows and represented up to altitudes of 380 m; (3) In the periglacial Pleistocene period, almost all the sands of the main areas had eolian processes; (4) Confirmation of the Podillya geological division into western and eastern with five morphological bands, proposed by W. Teisseyre; (5) Justification of the morphotectonic scheme of Podillya development, connected with tectonic elevations of the Hologoro-Kremenets Ridge, which caused the current inclination of the Podolsk hills to Southeast-East; (6) Statement that the tectonic lines of Berdo-Nârul and Kovalivka-Smykivtsi characterize the Paleozoic Platform of Podillya as a typical tectonic horst; (7) Detailed description of the Dniester “rinyshcha” (alluvial deposits) with the Carpathian material present in Podniester, Opil and Podillya itself, which are present as a strip at a distance of 14-20 km from the modern Dniester river bed; (8) Based on literary sources and his own research, the scientist came to the conclusion that there is “eolian” loess in the “rinyshcha”, sands and alluvial clay; (9) It is argued that the old Nadnistryan rivers cannot be older than the planation surfaces of the Carpathians and Pre-Carpathians; (10) Formation of the Dniester valley pattern in Pliocene and Pleistocene, which determined the direction of the flows of the left tributaries and their capture by the Western (Zakhidny) Bug river sources. Finally, in his “Prerequisites for Studying Morphology of the Podilsky Catchment Area of the Dniester” S. Rudnitsky managed to use a complex morphogenetic approach to studying the region relief for the first time geomorphological literature: from standardized morphological descriptions through systematization of the morphological structure of the region to the historical genetic interpretation of the main features of relief morphology. Key words: morphological districts; Dniester catchment area (basin); Naddnistriansky “rinyshcha” (alluvial deposits); glacial erratic material; fluvia-glacial deposits; free and entrenched meanders; “horbovyna” (land surface with hills); Podillya.

The article analyzes the concept of green routes and the peculiarities of their distribution and development in the countries of Western Europe. The activity of initiators of green ways in Ukraine is explored. The basic principles of the concept of sustainable development are set forth. The main components of the Green Way are described, in particular: the main axis “backbone trail” is marked, the network of various thematic trails and local routes is marked, the tourism product is consistent with the principles of sustainable tourism, there is regional partnership and a route coordinator, local initiatives are aimed at protecting the natural and cultural heritage The specified stages of the creation of the Green Way: Stage I: “Organization”, Stage II: “Visualization”, Stage III: Promotion and Distribution of the Tourist Product, Stage IV: “Support for Local Initiatives”, Stage V: “Creating Infrastructure on the Itinerary”. Three Greenways created in Ukraine are analyzed in detail. The first of them – “Valley of Two Years” was designed in 2016 in Kiev-Svyatoshinsky district of Kiev region. The peculiarity of this Green Way is primarily the activity of local residents. Thanks to their efforts, traditional activitiesnow include fairs, artistic and other events, triathlon and horse riding competitions, cycling routes. The River Irpin, which, despite overregulation, has preserved many features of the “wild” river, is now a venue for rafting. “Honey Circle” – the basis of the way is formed by theHoryn and Sluchabasins , passes along or near the river valleys. That is why the honey circle is the key to hiking in thecountryside – green, ecological, active, sports and other niche activities, as well as health and recreation. “PradavniiVelet – the basis of the route is formed by the valley of the Dniester River (almost 300 km) and its left-hand tributaries the Koropets, Strypa, Dzhurin, Seret, Tupa, Nichlava and Zbruch. The main tourist resources of the region are concentrated in the river valleys. That is why green (including ecological) tourism is the basis of the concept of development of tourism in the Dniester area. A new green way project has been proposed on the territory of the Lviv region, namely in Yavoriv district. Travelling inRoztochya, tourists, besides many nature reserve objects, can explore many architectural and archaeological sites, sacred buildings, and visit theirmuseums and galleries to see their history.

Full textAbstract:
The article describes the main stages of studying of the floodplain and the first floodplain terrace of the Dniester river within the Eastern Carpathian Foreland fragment of the valley, and evaluates the results of existing studies. It is discovered that during all the stages of the research morphological and morphometric parameters of the floodplain and the first floodplain terrace of the Dniester river, morphology and facie structures of the alluvial accumulations, as well as palynological analyses of biogenic accumulations buried in an alluvial series are performed. The results obtained during the palynological analyzes are used to date the erosion-accumulation cycles and to reconstruct the physical-geographical conditions of the time of the floodplain and the first floodplain formation of the Dniester terrace. The radiocarbon dating of biogenic sediments buried in alluvial series is also actively conducted at the last stage of the research. The array of geological and geomorphological information collected at the first two stages of research made it possible to establish that, first, the first floodplain terrace and floodplain were formed during the Holocene in the Dniester Valley. The first floodplain terrace (the height of which reaches 4–6 m above the Dniester riverbed) can be considered as a high floodplain which is often covered by high floods. The terrace is accumulative, but unlike all other terraces of the Dniester it is devoid of the loess cover. In the cross-sections of its accumulations the deposits of the alluvium of the channel facies builted of pebbles are exposed and covered with the alluvium of the floodplain facies composed of sands, sandy loams and loams. The total thickness of alluvium reaches 9–10 m and it doesn’t varysignificantly downstream of the Dniester. Except the Upper Dniester basin, where the thickness of the alluvium increases to 10–18 m, and the layers of peat are found. The floodplain is 4–5 m above the Dniester riverbed and is built of alluvium of the channel facies, dominated by sand and pebble series. In someplaces floodplain is covered with sandy or loamy deposits of floodplain facies. Secondly, in the Eastern Carpathian Foreland part of the Dniester valley the course of fluvial morpholitogenetic processes was regulated not only by climatic changes and neotectonic movements, but also by human economic activity. During the XIX–XX centuries especially large-scale human influence was on the Dniester riverbeds by construction of flood ramparts, reclamation canals, etc. The results of recent geomorphological research conducted within the studied fragment of the river valley particularly palynological and radiocarbon dating have significantly improved the idea of morphology, structure and history of floodplain formation and the first floodplain terrace of the Dniester. The research revealed that the accumulation of alluvium of the first floodplain terrace which is above the Dniester riverbed reaches 5,5–6,5 (7) m and started to develop in the late Pleistocene (Bølling–Allerød interstadial) (13 000–11 000 years ago (GI–1)). Presumably in the early Dryas (11 000–10 000 years ago (GS–1)), the first floodplain terrace was dissected by the meandering channel of the Dniester. The alluvial deposits that fill these large paleomeanders are still well preserved and are often exposed in the ledges of the first terrace. The further development of the floodplain and first floodplain terrace of the Dniester river was taking place in several stages such as the end of the boreal, the beginning of the atlantic, the end of the atlantic, subboreal, the beginning of the subatlantic, as well as during V–VI, X–XII and XIV–XVI centuries. These stages are identified in correlation with the cycles of humidification of the climate and the growth of fluvial activity of riverbeds (flood phases). As a result of the intensification of erosion-accumulation activity of the Dniester the two – three levels of Holocene floodplain were formed up to 4–5 m and 3–4 m high. The first traces of human activity within the studied fragment of the Dniester valley were dated by subboreal and recorded by the presence of grain pollen in the spore-pollen diagrams of Mainych (Upper Dniester Basin) and Tsvitova (Galician-Bukachiv Basin) sections. Key words: Dniester valley; floodplain; the first floodplain terrace; alluvium; phases of floods; Allerød; early Dryas; Holocene.

Full textAbstract:
The whole complex of terraces can be traced in the relief on the Vasyliv-Doroshivtsi area. Well-defined high terraces - XII (jr-kz), XI (bd-sv) and X (bv-br). The middle terraces in this area are narrow, poorly preserved in relief. The inner-canyon part of the Dniester valley is relatively wide, which contributed to the development and preservation of a full complex of lower (late Pleistocene) terraces: the fourth (kd-ts), third (pl-ud; fragmentary), second (vt-bg), first (df-pc) terraces, as well as Holocene high and low floodplains (hl). Researches of features of the structure of low terraces carried out on the basis of a survey of geomorphological surfaces, outcrops of terrace deposits, the analysis of boreholes, fossil vertebrate and mollusc faunas, and also results of long-term observations during archaeological researches of site Doroshivtsi 3. The first above-floodplain terrace (df-pc) is represented by small fragments. It is composed by channel facies of alluvium, represented mainly by pebbles. Above them the floodplain facies - fine- and medium-grained sand, light grey, obliquely and horizontally layered, are bedded. The floodplain alluvium is covered by a low-thickness stratum of loess-like loams (pc). To the west of Doroshivtsi Village, near the Hlynyshche site, the upper layer of sediments is partially destroyed and buried under the sediments of a high floodplain. Only the remains of the lower part of the section are partially present. That is, in this area, the roots of the first terrace serve as the base of the high floodplain. The second terrace (vt-bg) is most clearly manifested morphologically due to the ledge, which stands out quite clearly. It is better developed within the Vasyliv Village. Here it is quite extensive, its surface is planned. In the area of Doroshivtsi, this terrace is narrow, severely damaged, occurs in fragments. The basement of the terrace is located at the height of about 1 m above the current level of the Dniester River. It is composed of dark green-grey argillite and coarse-grained Devonian sandstones. The structure of the terrace is as follows: the channel facies (gravel-pebble deposits with inclusions of boulders and sand aggregate) and powerful floodplain facies of alluvium: rhythmic layers of sands, sands and loams with signs of embryonic soils); complex of fossil soils and forests (forest-like loams) - bg-pc. Numerous remains of molluscs, mega- and microfauna, remains of material culture were found in the terrace deposits (Doroshivtsi 3 site). The third terrace (pl-ud) is weakly expressed and narrow. There are no outcrops of its sediments here and no boreholes. Therefore, currently, its structure in the study area remains unknown. However, in the lower part of the sediments of this terrace during the digging of the well were found fragmented remains of a mammoth (Mammuthus sp.) and a red deer (Cervus elaphus) with traces of disposal (site Vasyliv II). At another location, a mammoth tooth was found, which we identified as Mammuthus primigenius cf. jatzkovi. Fourth terrace (kd-ts). Terrace sediments are exposed to the west of Vasyliv, also discovered by a borehole near the basement of the white-stone temple of the XII-XIII centuries. According to drilling data, the top of gravel here is at the height of 7 m above the boundary level of the Dniester River. Above the gravel are bedded (from bottom to top): a layer of chernozem-like paleosol (pl); the light yellow loess with a columnar structure (ud); brown paleosol (vt); the pale yellow, carbonate loess, with also a columnar structure (bg). According to the terraces' classification by their location in the river valley, low terraces in the study area of the Middle Dniester are incised. According to the genetic classification, they can be considered accumulative, closed- or hidden-socle. Thus, based on the row of data, the peculiarities of the structure of low terraces, the composition of sediments and their approximate geological age have been established. New sections of the second and fourth terraces are described based on the study of outcrops and drilling data. New locations of vertebrate and mollusc fauna have been discovered in the deposits of 2-4th terraces in the village of Vasyliv. The considerable width of the second floodplain terrace in the Vasyliv area in comparison with Doroshivtsi testifies to the prospects of finding here the remains of material culture, similar to the Doroshivtsi-3 site. As a result of research, we established that due to the different history and mechanism of sediment formation, the structure and composition of sediments of the same age terraces may differ. This fact should be considered when allocating terraces and rely not only on the features of the cover part of the sediments but on the set of characteristics of a terrace. The questions of the peculiarities of the fourth and first above-floodplain terraces' structure, as well as the depth of basement of the high floodplain, remain unclear.

Full textAbstract:
AbstractInformation about the morphology and alluvial sediments of the Dnieper Valley is reviewed. The Dnieper Valley originated in the Late Miocene. The Middle Dnieper Valley is an intercontinental alluvial basin and the Lower Dnieper Valley is a shallow canyon that ends with a delta. Identification of the alluvial dynamic facies (channel, overbank, abandoned channel) is crucial for stratigraphical analysis. The dynamic facies form regular sequences - alluvial suites that combine into series. Individual suites and series are characterized by their mode of occurrence, facies composition, lithological features and expression in the modern landscape. Their stratigraphie position is established with reference to index beds and palaeontological, geochrono-logical and archaeological research, allowing them to be correlated along the valley. Correlation between different parts of the Dnieper system uses a combination of facies and geomorphological analyses, whereas correlation with other river systems makes use of mammalian and molluscan biostratigraphy. Global events (marine regressions and glaciations) that brought about similar reactions in different fluvial systems can be also used for correlation.

Purpose. The research is aimed to obtain some missing data on the morphology of river sands within the city, in particular, reliable quantitative indicators that can be used in the calculation of soil bases. Methodology. According to the experimental-analytical method, a complex soil morphology was used, which takes into account the shape and nature of the grain surface in the entire sand volume studied. Morphological assessment was carried out not only for individual sand particles, but also for the entire volume of the soil studied, due to this an important factor in the formation of the shape and nature of the sand grain surface is the mineral composition of sand. For the most of the studied sands, quartz was the predominant mineral. In further studies, it is planned to study the Dnipro River sands of deeper horizons, which would make it possible to obtain data on the formation of contacts between sand grains, which can be lamellar or other shapes. Findings. This paper presents the results of determining morphological indicator, as well as studying the shape and nature of the surface of alluvial sand grains of the 1st floodplain terrace of the Dnieper River valley in the area of Monastyrskyi Island in the central part of the city. The results of similar works on the study of a number of genetic types of Quaternary sands of various genesis in the Dnieper River valley were also analyzed. Due to this analysis, data were obtained on the morphology of monomineral oligomictic alluvial sands, the shape and nature of the alluvium sand grains surface. Originality. For the first time for the central region of the city, some basic morphological characteristics of river Quaternary sands of the Dnieper River valley were obtained. It is also possible to note the tendency of decrease of morphology indicator in river sands of the Dnieper valley from sources to the mouth. Practical value. With all confidence, the results of the studies carried out can be implemented in the sandy soils of the foundations of buildings and structures of the city, as well as to artificial earthworks, in particular, alluvial massifs.

Full textAbstract:
The publication highlights the regional conditions for the implementation of paleotours, as the basic components of the structure of the complex route "Terra Podolica", the territory of Podolsk Transnistria. The main features of paleotours on the basis of territorial locations with the characteristic of technical aspects of their realization are revealed. Leading fossils have been identified that can become regional paleobrends and can be used as a means of promoting geotourism. The conditions for effective implementation of paleotours in the regional recreational complex of the Podolsk region are established. The analysis of efficiency of perspective formats of development of geotourism on the basis of regional conditions is carried out.
The development of geotourism in the Podolsk region has strong prerequisites: resource base, tourist flow and developed tourist infrastructure. At the same time, among the specialized forms, only the speleological direction is actively developing. Other geotourism components are limited to mentions or brief demonstrations of individual objects during sightseeing tours. Popularization of the direction is just beginning, and geotourism products are in the state of development and experimental testing. In particular, the paleontological direction, which has examples of successful implementation of abstract implementation (for example: dinosaur parks without reference to the region), using the resource capabilities of Podillya effective formats can become branded. The main theoretical aspects to be addressed are: focusing on particularly interesting regional fossils that can be interpreted as values and reveal through their prism geological history, features of modern landscapes and, if possible, regional cultural and economic phenomena, selection of effective forms of interactive interaction and development on their basis of competitive tourist products, formation and equipment of locations for realization of tourist products, popularization of the direction and interest in its realization of local economic, educational and nature protection subjects.
In middle Transnistria, the valley and river landscapes change markedly from west to east (or vice versa). The main reason for this is the differences in lithological structure, emphasized by the shape of the slopes, the color of the rocks and the height distribution of plant tiers. This in turn affects the configuration of settlements, patterns of location of buildings, architectural composition of buildings, distribution of farmland. In combination with historical traditions, unique landscape and cultural entities are formed, promising for the organization of thematic tours.
The visual change of geological deposits in the region is due to the lithological features of the structure, especially the Domezozoic tier. It is clearly visible in river valleys and weakly expressed in watersheds. In general, each large tributary of the Dniester corresponds to an "individual" lithological complex. Its features are preserved along the meridional extension of the watercourse with bright local manifestations in areas of tectonic activity. The effect of contrast occurs when laying a route across river valleys, when passing the watershed, the observer falls into another "landscape reality"
Paleontological tours are considered by the authors focused on increasing the tourist attractiveness of the region, attracting untapped resources, optimizing tourist products within specific locations, developing innovative areas and forms of tourism and interaction with local economic systems of united territorial communities. The specifics of the organization of paleotours allows you to create a new economic niche with a staffing offer for specialists in natural specialties.

This article is devoted to the typology of lakes of the North-Steppe Dnieper. In developing the typology of lakes, the parameters were taken into account: landscape location, hydro-chemical and hydro-biological characteristics and the degree of their anthropogenic transformation. The data presented are based on the processing of stationary and route research materials from 1998 to 2018 on the lakes of river valleys: Dnieper, Samara, and Orel. Hydrological indicators are analyzed according to the literature, cartographic and archival data of the Dneprodiprovodkhoz Institute and the Biology Research Institute of Oles Honchar Dnipropetrovsk National University. Floristic studies were carried out using general botanical methods of collection and herbarization, and in the study of typical aquatic flora - special hydro-botanical methods. Geo-botanical studies were carried out according to geo-botanical and special hydro-botanical methods. The article presents the hydrological and hydro-botanical features of the lakes of the valley of a large river (Dnieper) and medium rivers (Samara, Orel). Lakes are located exclusively in valley-terrace landscapes in the northern part of the steppe zone of Ukraine. Despite this, based on cartographic materials, we proposed zoning of the territory of the lakes of the North-Steppe Dnieper according to the criteria: their location in lake regions, in various landscapes and the degree of anthropogenic transformation. The following districts and subareas were identified: Dnieper Lake District (Dnieper floodplain lake subarea with slight flooding of the floodplain, Dnieper Lake subarea of floodplain terraces, Dievsky floodplain lake subarea); Samara Lake District (Lake Subarea of Samara Coniferous forest, Lake Subarea of Estuary part of Samara); Orel Lake District. Lakes are located in various physical and geographical conditions of the floodplain, arena and third saline terrace. The typology of the lakes of the North-Steppe Dnieper basin was developed on the basis of regionalization of the location of the lakes, distribution according to the ecological and topographic profile, hydrological, hydro-chemical regimes, degree and nature of overgrowing. 11 types of lakes are identified based on the above criteria. 6 types were identified for the valley of a large river: floodplain lakes (3 types) with a long-flow regime, lakes of the second (sandy) terrace (2 types) and highly mineralized lakes of the third (saline) terrace. 5 types were identified for the valleys of middle rivers: floodplain lakes (3 types) with an episodic short-burial regime, lakes of the second (sandy) terrace (low-mineralized) and excessively mineralized lakes of the third (saline) terrace.

Geophysical techniques Ground Penetrating Radar (GPR) and Electrical Resistivity Tomography (ERT) are used for the geological mapping and description of inner structure of sediments of the Upper Dnieper zone. Geophysical data assisted locating the boreholes and correlation the horizons between them. The information obtained by geophysics provided a basis to identify the rerouting of the upper Dnieper valley due to the Valdaian glaciation. GPR data on frequencies 50–250 MHz allowed to describe the upper part of geological section, ERT provided data up to 80–100 m depth. We performed the modified focusing inversion, based on major boundaries obtained with GPR, to correct ERT inversion model.

Floodplain valley of the Dnieper river midstream is a unique natural complex, having a great bìogeographical, ecological, environmental, historical and recreational values. In 1990, the Natural reserve «Dniprovsko-Orilsky» was established within the area. The Natural reserve «Dniprovsko-Orilsky» is environmentally protected site within the Dnipropetrovsk region, Dnipropetrovsk oblast, Ukraine. This reserve occupies part of the Dnieper river valley and marshy and reedy banks of Protovch river (existing bed of Oril river). It was created by Regulation of the Council of Ministers of the USSR of 15 September 1990, No. 262, based on common zoological and ornitological Nature reserves «Taromskì plavni» and «Obukhovskie zaplavy». On the territory of the Natural reserve «Dniprovsko-Orilsky», they were registered 32 Lepidoptera species listed in the List of Threatened Species at different categories (5 species in IUCN Red List ; 18 in Red Data Book of Ukraine; 7 in European Red List of plants and animals endangered on a global scale; 31 in Red Book of Dnipropetrovsk oblast). The main scientific materials were author’s collections from area of research and materials of entomological funds, Department of Zoology and Ecology, Oles Honchar Dnipropetrovsk National University (mostly Memorial Collection of V. O. Barsov). Field surveys covered all the ecosystems basic on size and degree of protection. The author’s researches have conducted over the past decade during annual expeditions to the Reserve. Taxonomic structure of the complex is quite diverse, and represented by all the major families of higher millers and rhopalocera, having protectedstatus. In relation to taxonomy, this complex formed by representatives of five superfamilies (Zyganoidea, Noctuoidea, Bombycoidea, Hesperioidea, Papilionoidea) from 11 families (Zygaenidae, Saturniidae, Sphingidae, Noctuidae Arctiidae Hesperiidae, Papilionidae, Pieridae, Nymphalidae, Satyridae, Lycaenidae). High taxonomic diversity can be explained by unique geographical location of the reserve in azonal conditions of the Dnieper river valley. Such location allows to enter different zoogeographic Lepidoptera groups on the reserve territory. Zoogeographic analysis of species protected within the reserve territory selected 7 basic groups. It was found that most of the globally rare species have Mediterranean origin (39 %); species of Palearctic origin are in second place (22 %); Western Palearctic and Ponto-Kazakh types of areas are same of number of species, and come third (11 %); and others come 17 % (European, Euro-Siberian, and Holarctic). This fauna component is specific due to presence of so-called «northern» species that make up 40 % (representatives of Palearctic, Western Palearctic, Euro-Siberian, European and Holarctic groups). Their existence within the reserve territory is only possible due to development of boreal valley ecosystems.

Full textAbstract:
In the paper, there is a characteristic of hydrochemical properties of the groundwater lying within the river valley of Samara Dniprovska, on the steppe plakor areas, under the automorphic soils and the water of the Samara River. In characterizing of the hydrochemical properties of the groundwater the author came from the fact that the groundwater, according to the previous studies (Kotovich, 2010, 2014), with varying degrees of share participation, is an integral part of the water balance of forest ecosystems and used by the wood vegetation. Based on the landscape principle of groundwater formation there are those that lie within the valley of the river Samara, as well as the groundwater of steppe plain regions with automorphic soils and areas with developed gullies and ravines. The groundwater of the river valley for its hydrochemical properties is not homogeneous, and there is a clear binding of hydrochemical indicators to the main geomorphological elements with typical for them soil cover. It was established that the groundwater of flood plain lying directly in the area of undermining near the town of Ternivka is the most mineralized – 1928 mg/dm3, due to slow water exchange with surface water because of sedimentation of the surface. Out of the influence of undermining zone the floodplain groundwater do not differ from the zonal groundwater; its mineralization is 1560–1050 mg/dm3. The groundwater of sandy terraces of the Samara river valley has azonal signs, namely – reduced salinity (110–150 mg/dm3), hydrocarbonate and calcium ion composition and acidic reaction of pH (4,5–5,7). It is noted that due to favorable filtration properties of sandy soil, salt concentration varies synchronously with the fluctuations of groundwater level. At the same time in the area of coal mining with transformed soil and hydrological conditions the groundwater has a higher salinity than the groundwater, lying outside the influence of mine water drainage, while the dynamics of change in mineralization lags behind fluctuations in the groundwater level for more than three and a half months. Within the third terrace of the Samara river valley the mirror of the groundwater begins at a depth of 1,5 m. The total mineralization – 2640 mg/dm3 – is significantly higher than in the groundwater of the first and the second terraces. The ion composition is dominated by sodium and chloride ions, and the pH reaction is close to neutral. The groundwater of the watershed areas between the Samara and Oril rivers lies at a considerable depth – 20 m, has mineralization of 2100 mg/dm3, and the ionic composition is dominated by chloride ions and calcium. At the same time, the groundwater in the area of developed network of gullies and ravines has a lower mineralization – 650 mg/dm3. It can be assumed that the differences are related to the terms of draining of aquifers. Analysis of long-term data of salinity in the Samara river demonstrated an increase in this index from 1738 mg/dm3 in 1929 to 3540 mg/dm3 in 2006.

Abstract This article presents the features of the phylogenetic organization of the plant communities of the Dnieper River terrace within the ‘Dnieper-Orilskiy’ Nature Reserve and the patterns of its spatial variation involving remote sensing data of the Earth’s surface. The research materials were collected in the period 2012−2016 from within the nature reserve. The research polygon is within the first terrace (arena) of the Dnieper valley. Sandy steppe, meadow, forest and marsh communities within the Protoch river floodplain and the Orlova ravine, as well as artificial pine plantations were the habitats present within the research polygon. The vegetation description was carried out on 10×10 m (100 m2) plots. A total of 94 geobotanical descriptions were made. Data on plant phylogeny was obtained by the Phylomatic service. Phylogenetic diversity of the communities was assessed by the Faith, Simpson and Shannon indices. Phylogenetic analysis was performed by means of a double principal coordinate analysis (DPCoA). The vegetation cover within the investigated polygon was represented by 189 species. Abundance Phylogenetic Deviation (APD) for the investigated metacommunity was evaluated to −0.53, which is statistically significantly different from random alternatives (p = 0.001). The APD negative value indicates that phylogenetic organization of the investigated metacommunity is overdispersed. The permutation procedure allowed us to establish that the eigenvalues of the DPCoA-axes obtained as a result of the real phylogenetic tree were significantly higher than their own number for the random phylogenetic trees for the first seven axes. This indicates that the first seven axes are useful for additional information on the ordination structure of the metacommunity.

The geological structure of Neopleistocene deposits was specified along a 19-kilometer section of the right bank of the lower Pechora between the villages of Garevo and Sergeevo-Shchelya. The presence of three glacial and two interglacial horizons was revealed in coastal outcrops, and the material composition of the composing sediments was studied. The formation of the most ancient moraine horizon was associated with Fennoscandinavia and occurred in the early Quaternary Pomusov (Oka) time. The Pomusov moraine was overlain by Chirva (Likhvin) interglacial alluvial and lacustrine sediments. In the Middle Neopleistocene glacial complex, two morainic strata of different ages were distinguished: Pechora (Dnieper) and Vychegda (Moscovian), separated by a pack of predominantly coastal-marine littoral sediments, and alluvial and lacustrine sediments, the age of which was determined as Rodionov (Shklov) by the palynological method. Differences in the lithological composition of moraines confirmed a double glaciation of the European North-East of Russia in the Middle Neopleistocene.

The article is devoted to the kurgans which are located on the 45 km long cape, formed by the valleys of the Yagorlyk and Sukhyi Yagorlyk rivers, which merge at the left bank of the Dniester. These burial mounds were mentioned and even painted by J. A. Münz (1781), and then described and put on cards by A. K. Meyer and F. P. de Volan (1791).
Topographers and archaeologists have noted up to 120 mounds reaching a height of 8—9 m in this local region. Most of them are stretched along the top of the watershed, some groups stand with two parallel lines, a number of chains of kurgans are oriented across the watershed. In general, they mark the site of the ancient trade route, along which it was possible to travel from the Dniester to the north to the forest-steppe; to the east to the Dnipro region and to the south-east to the Danube delta and the Black Sea.

In the latitudinal section of the Pechora, two horizons of boulder loams (moraines) and underlying horizons, dividing or overlapping the moraine strata, are exposed to intermoraine sediments of fluvial genesis. Based on the results of lithological studies of textural, granulometric and mineralogical features of fine earth of deposits and petrographic composition of coarse material, it was concluded that material was supplied during the formation of moraines from different terrigenous-mineralogical provinces. The formation of the lower Pechora (Dnieper) moraine is associated with the North-Eastern feeding province, and the upper Moscow (Vychegda) moraine, with the North-West Fennoscandian center of glaciation. The glacial genesis of boulder loams has been confirmed.

Full textAbstract:
The escarpment-surrounded Sage Creek and Scenic Basins open in southeast directions toward the northeast and east oriented White River valley while their floors drain in a northwest direction to the northeast oriented Cheyenne River. Located in the South Dakota Badlands region the Sage Creek and Scenic Basins present an intriguing drainage history problem where key puzzle pieces also include the White and Cheyenne River valleys. The puzzle solution requires massive amounts of southeast oriented water to first erode as deep headcuts the east oriented White River valley segment and the two southeast-oriented Sage Creek and Scenic Basins prior to Cheyenne River valley headward erosion. The northeast oriented White River valley segment upstream from the east oriented White River valley segment (and from the Sage Creek and Scenic Basin location) next eroded headward across southeast oriented flow and was initiated by southeast oriented water flowing from the Scenic Basin that turned in a northeast direction to reach the east oriented White River downstream valley segment. Erosion of the Sage Creek and Scenic Basin headcuts abruptly ended when headward erosion of the northeast oriented Cheyenne River valley beheaded southeast oriented flow routes leading to the then actively eroding Sage Creek and Scenic Basin heacuts. Cheyenne River valley headward erosion in a southwest direction next captured massive southeast oriented flow then still moving to the newly eroded northeast oriented White River valley segment. Northwest oriented drainage developed on the Sage Creek and Scenic Basin floors when a flood surge or temporary dam caused water to fill the White River valley and to spill in a northwest direction across low points on the then abandoned Sage Creek and Scenic Basin headcut rims. This spillage eroded narrow northwest oriented valleys and drained water filling the two basins to the Cheyenne River valley while most of the ponded water drained in an east direction down the White River valley. The White River valley, Sage Creek and Scenic Basins, and the Cheyenne River valley were eroded by enormous quantities of southeast oriented water that also deeply eroded the entire South Dakota Badlands region.

Full textAbstract:
This publication presents the analysis of the mostly used international and Ukrainian classification systems for wetland areas performed for identification of different-type marsh biotopes of steppe rivers in the Northwest Black Sea Region. Among the classification systems, the most well-known are the Ramsar Classification System for Wetland Type (1971) and Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al., 1979). In these systems, valley marsh biotopes are identified as riverine and palustrine, non-tidal, unstable (perennial impounded and seasonal/intermittent) freshwater marshes on mineral rich soils predominantly covered by grasslike plants (rush, reedmace, sedge). The delta marshes of the Danube, Dniester and Dnieper are referred to as tidal brackish and freshwater marshes. According to Ukrainian classification systems for hygromorphic geosystem, marsh biotopes are regarded as mouth wetlands, which is peculiar to delta marsh areas of the Danube and Dnieper interfluve. Thus, riverbed marshes of small and medium-sized rivers are located in other areas and are usually met both in the lower (continuous marsh areas), middle (fragmented marsh mosaic), and upper (coastland) river flow areas, which is caused by an unstable watercourse rate and transforming of their riverbed parts into marsh sections covered by eurytopic wetland species.

Full textAbstract:
Unisexual forms of lower vertebrates (fish, amphibians, and reptiles) reproduced by parthenogenesis, gynogenesis, or hybridogenesis are represented by diploids, triploids, or tetraploids, whose origin is associated with interspecific hybridization. Among fish species, the highest variability of unisexual polyploids was found in the genus Cobitis. The structure of their genomes and putative parental species holds great interest for the investigation in association with questions about possible evolutionary success. In particular, it serves to elucidate the possible high colonization properties of a few polyploid forms, in contrast to the local history of rather numerous hybrid forms with a limited distribution. Therefore, the aim of this study was to describe the karyotype structure of two newly discovered triploid forms of the genus Cobitis, to analyze their origin and putative parental species. The karyotype structure of 182 spined loach individuals from the Western Dvina River and 91 individuals from the upper Dnieper River of the Smolensk District of Russia was studied. A total of 121 studied individuals from the Western Dvina comprised triploid females with a chromosome number 74 and karyotype consisting of 13 meta-, 39 submeta-, and 22 subtelo-acrocentric chromosomes. Among loaches collected in the upper Dnieper River, 42 triploid females were found with 74 chromosome number including 23 meta-, 26 submeta-, and 25 subtelo-acrocentric chromosomes. Other individuals from both localities were karyologically identified as Cobitis taenia Linnaeus, 1758 with 2n = 48. The triploid form of spined loaches of the Western Dvina River most likely arose as a result of the hybridization of Cobitis tanaitica Bǎcescu et Mayer, 1969 and C. taenia. The range of C. tanaitica, whose karyotype is characterized by an evolutionarily fixed Y-autosomal translocation, is limited to the rivers of the northern coast of the Black Sea. Therefore, hybridization probably happened in late Pleistocene in the Dnieper River system, where both parental species occur. The triploid form that arose here is unique for the Baltic Sea basin. Probably, it colonized the Western Dvina through the artificial Berezinskaya water system (Berezina Canal = Daugava–Dnieper Canal), but at the same time it was forced out of its area of origin by other triploid forms which are now widespread there. According to the karyotype structure, the triploid form, common for both the upper and lower reaches of the Dnieper, has a trihybrid origin, with probable hybridization of Cobitis elongatoides Bǎcescu et Mayer, 1969, C. tanaitica, and yet unidentified species Cobitis sp. Both studied triploid forms are parts of unisexual-bisexual complexes, in which their putative diploid maternal species (C. tanaitica and C. elongatoides) are absent, and the role of the host species involved in reproduction belongs to C. taenia.

Full textAbstract:
Along the middle reaches of the Dnieper River in central Ukraine, braided riverbeds with many islands have developed in alluvial valleys. 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). In this paper, we assess the hydromorphological parameters of the studied river reach as well as the characteristics of the related erosion and deposition zones. Therefore, a monitoring framework for channel processes (MCP) downstream of the Kaniv HPP was installed. The analysis of the intervention discharge parameters was conducted based on measurements from July 2015. Channel stability was expressed by the following factors: Lohtin’s number (L), Makkaveev’s (Kc) factor of stability, and a complex index of stability (Mx) by Grishanin. This study shows that the velocity of artificial wave propagation may reach a speed of up to 74.4 km·h−1. The wave propagates for a distance of approx. 45 km within 65 min at a mean velocity of 37.4 km·h−1. The L, Kc, and Mx indicators used in this work showed that when water discharge increased (e.g., during typical peak-capacity operation), the channel becomes unstable and sediments are subject to erosion processes. The riverbed stability indicators clearly illustrate that an increase in parameter values is not dependent on the distance to the dam. The results are valuable for sustainable sediment management at catchment scale and hence, directly applicable in water management.

Full textAbstract:
The article is devoted to the coverage of a little-known aspect of D. Ya. Telehin’s scientific activity, namely his research related to Palaeolithic sites and Palaeolithic issues. Although this was clearly not the main area of the scientist’s concern, his interest for Palaeolithic studies has accompanied him throughout his scientific life.
In the early 1950s, D. Ya. Telehin participated in the works of I. F. Levytskyi at the site Mynivskyi Yar at Seversky Donets, in eastern Ukraine. The lower layer of the site belongs to the period 18—13 thousand years ago. In fact, at the time of excavations, it was the only Upper Palaeolithic site in the region that was investigated on a relatively large area.
In the mid-twentieth century, a cascade of new hydroelectric power plants and reservoirs was being built on the Dnieper. During the field seasons of 1953 and 1957, D. Ya. Telehin’s explorations in the area of construction of the Kakhovskaya hydroelectric power plant and the Kakhovskoye reservoir discovered, in addition to numerous sites from later periods, the first upper Palaeolithic locations of the Lower Dnieper, namely: Shyroka, Valivalska and Merzlyakova gullies.
In 1975 together with N. I. Tarasenko, D. Ya. Telegin conducts excavations at the Rogalyk farm. According to modern interpretation, the remains of three new stratified sites were discovered during these works. The authors have identified the materials as early Mesolithic; they are now attributed to the final Palaeolithic.
In 1976 D. Ya. Telehin researches the Upper Palaeolithic site of Zbranky near the eponymous village in the Ovruch loess area. The materials found once again, after the works of I. F. Levytskyi and V. A. Mesyats, confirmed that this region was actively exploited by the Palaeolithic man at the end of the Pleistocene.
A number of new, mostly surface, Upper Palaeolithic sites were discovered by the «Dnieper-Donbas» and «Slavutych» expeditions led by D. Ya. Telehin in 1970—74 and 1980—83 on the territory of the Middle Dnieper Basin (Chernyavshchyna, Pereschepyno, Khizhnyakivka, etc.) and the middle reaches of Southern Buh (Apolyanka, Berezyno).
During the 1980s, D. Ya. Telehin investigated the area of the left bank of the Dnieper River near the mouth of the Sula River. This work resulted in the discovery of a new concentration of Upper Palaeolithic sites. The features of lithic assemblages make it possible to identify groups of later and earlier sites in the preliminary view, including the so-called archaic Upper Palaeolithic.
In 1984, D. Ya. Telehin investigated the location of Semenivka 1 in Baryshevsky district of Kiev region in the valley of Trubizh river. The peculiarities of the stone tools allowed to see the nearest analogies to the findings in the materials of the sites of Epigravettian mammoth hunters. Studies at Semenivka 1 gave an impulse for further searches in this area.
The brief overview offered shows that although Palaeolithic studies were not in the focus of D. Ya. Telehin’s attention, his works are nevertheless deservedly included in the general fund for achievements in domestic Palaeolithic studies.

The archaeological heritage of Liubech (Lyubech, Chernihiv region, Ukraine) includes various monuments and objects from the Bronze Age to early Modernity (2000 BC – 17th century) with small time gaps. Archaeological surveys in Liubech began in the late 19th century and have continued until today with certain interruptions. Despite the close attention paid by scholars to the archaeological monuments of Liubech, it should be noted that the area of the city within its administrative boundaries (both the floodplain part of the Dnieper River and the densely developed part of the town) has not been sufficiently studied.

Full textAbstract:
Topographic map evidence in the western North Carolina French Broad River drainage basin (upstream from Asheville) was used to determine if a new geology and glacial history paradigm (new paradigm) can explain previously unexplained (and anomalous) drainage system evidence. The new paradigm claims: 1) the Eastern Continental Divide was uplifted as the southeastern rim of a continental ice sheet created deep “hole” (in which the ice sheet was located) as immense and prolonged southwest-oriented meltwater floods flowed across it, 2) headward erosion of south and southeast-oriented valleys (in sequence from the southwest to the northeast) diverted floodwaters more directly to the Atlantic Ocean, and 3) headward erosion of north- and northwest-oriented valleys from the developing deep “hole” (in sequence from the southwest to the northeast) diverted floodwaters to deep “hole” space (located between the rising deep “hole” rim and the ice sheet margin) and then toward deep “hole” southern exits (eventually the Mississippi River valley became the only southern exit). The new paradigm permitted the following types of drainage system evidence to be explained:1) numerous barbed tributaries flowing to a northeast-oriented French Broad River segment, 2) a larger than required northeast-oriented French Broad River valley, 3) and diverging and converging valley complexes which are found throughout the northeast-oriented oriented French Broad River headwaters drainage basin. In addition, the map evidence could be interpreted to show: 1) headward erosion of the north- and northwest-oriented French Broad River valley captured southwest-oriented flow to the north-oriented Pigeon River valley which had captured flow to the northwest-oriented Little Tennessee River valley, 2) headward erosion of the south-oriented Broad River valley captured southwest-oriented flow to the northeast- and north-oriented French Broad River and the south-oriented Toxaway River and 3) and multiple gaps identify locations where southwest-oriented water entered and exited the present-day French Broad River headwaters drainage basin.

In photographs, however, the Sich Riflemen look like ordinary Austrian-Hungarian soldiers. There is nothing specifically “Cossack” about their appearance. In 1914, Sich simply stood for the military or paramilitary activity of young Ukrainian males. Every soldier in the Legion of Ukrainian Sich Riflemen was now, by definition, a Sich man, a Cossack. The Cossack characteristics suggested by the term “Sich” had become inextricably linked with alleged Ukrainian martial valor.

Full textAbstract:
Terraces in the lower Matane River Valley (eastern Quebec, Canada) were studied to describe the stratigraphic architecture of a glacially eroded valley fill. The Matane River Valley hosted a glacial tongue connected with a regional ice cap during the early opening of a calving bay in the modern St. Lawrence Estuary and was subsequently flooded by the Goldthwait Sea as the Laurentide Ice Sheet margin retreated. Stratigraphic, sedimentological, light detection and ranging (LIDAR), and geochemical analyses as well as radiocarbon measurements allowed the identification of four stratigraphic units deposited during and following deglaciation: glacial outwash (unit I), delta bottomsets (unit II), delta foresets (unit III), and fluvial deposits (unit IV). Stable isotope (13C) and C/N ratio values reveal the relative influence of the two end-members (algae and terrestrial plants) on organic matter sources between the stratigraphic units. Climate, major relative sea level fluctuations, and sediment yield are recognized as the main controls on depositional environments in glacially eroded valleys of the northern shore of the Gaspé Peninsula during the Holocene. This paper presents a model of the evolution of the Matane River Valley, which in many points is similar to existing conceptual fjord-valley fill models.

AbstractThe Humber River in western Newfoundland flows through a large interior basin, that influenced Late Wisconsinan ice flow from major dispersal centres to the north, in the Long Range Mountains, and to the east in The Topsails. An early southward ice flow from a source to the north covered coastal areas in the western part of the basin. Subsequent regional ice flow was southwestward to northwestward from The Topsails, while south to southwestward flowing ice from the Long Range Mountains occupied the upper Humber River valley. This flow was confluent with ice from The Topsails and moved northwestward toward Bonne Bay. Regional deglaciation began about 13 ka from the inner coast. Ice occupying the Deer Lake valley dammed glacial Lake Howley in the adjacent Grand Lake and Sandy Lake basins to an elevation up to 85 m above present lake levels, which were controlled by drainage through a western outlet feeding into St. George’s Bay. The lake was lowered by exposure of the South Brook valley outlet, and finally drained catastrophically through a spillway at Junction Brook. Marine limit at the coast was 60 m asl. Inland deltas at the head of Deer Lake and fine-grained sediment exposed in the Deer Lake valley show inundation below 45 m present elevation. This produced a narrow embayment extending at least 50 km inland from the modern coast and is named here as ‘Jukes Arm’. Dated marine macrofossils in the Humber Arm and lower Humber River valley, indicate the deltas at the head of Deer Lake formed about 12.5 ka.

Several field trips were carried out in 2022 and 2023, aiming to investigate the water quality parameters, ichthyofaunal and floristic diversity in some areas of Gurban Valley, located in the protected area Natural Park Comana, Giurgiu County, southern Romania. Throughout the study period were identified fish specimens belonging to nine species: Prussian carp Carassius gibelio (Bloch, 1782); Gobio obtusirostris Valenciennes, 1842; Dnieper chub Petroleuciscus borysthenicus (Kessler, 1859); Roach Rutilus rutilus (Linnaeus, 1758); Danubian spined loach Cobitis elongatoides Băcescu & Mayer, 1969; Belica Leucaspius delineatus (Heckel, 1843); Southern ninespine stickleback Pungitius platygaster (Kessler, 1859); European bitterling Rhodeus amarus (Bloch, 1782) and European mudminnow Umbra krameri Walbaum, 1792. A total of 147 captured specimens were measured, weighed and photographed. For the capture of fish, minnow traps and plankton nets were used, on the Gurban River, right tributary of the Neajlov River, Giurgiu County. The floristic inventory compiled so far included 58 plant species grouped into 31 families, with European, circumpolar, Eurasian, eurasiatic continental or cosmopolitan distribution. Related to physico-chemical characterization of water samples collected from four sampling points (SP), the results of laboratory analysis allowed to frame the water into quality classes and to evaluate if the water meets the requirements for aquatic organisms. Hence, on the basis of nitrite-nitrogen (N-NO2-) and nitrate-nitrogen (N-NO3-) water corresponds to Ist quality class, meanwhile chemical oxygen demand (COD), phosphate-phosphorus (P-PO43-) and ammonium-nitrogen (N-NH4+) allowed to associate water quality with IIIrd class. In addition, it has been found very significant correlations between electrical conductivity (EC) and total hardness (TH) with r=0.9230*** and between pH and TH with r=0.8821***, respectively.

Rescue archaeological excavations at the Trypillia settlement of Hordasivka-II (Zvenigorodka district, Cherkassy region) were started in 1996. This settlement is located at western bank of Hirs’kyy Tikych river, in 2.5 km to the west from the south-eastern edge of the village. It is placed on a part of plateau formed by the creek valley from the north and long cavin from the east. Visual observations indicate elliptic structure composed of a single row of dwellings. Settlement size did not exceed 3 ha. The rectangular-shaped Dwelling 1 excavated in Hordashivka (12.5 x 5.0 m) was oriented from north-west to southeast. It is reconstructed as a house with the lower storey’s floor covered by clay and massive ceiling of the lower storey (= floor of the upper storey). Most of the interior details were found on the floor of the lower storey. These are the fireplace, working space, elevations. Collection of finds is mostly represented by pottery (70% of the assemblage is referred to kitchen pottery and 30% of the assemblage is referred to table pottery). Part of the table pottery is decorated in black monochromic painting. Analysis of ceramics allows dating the settlement to Tripolye CII. Considering the relative and absolute chronology (radiocarbon dates obtained for Sharin III), this site may be dated to c. 3400 – 3200 BC. Materials from Hordashivka are “genetically” linked to post-Kosenovskaya group populations in the Southern Bug and Dnieper interfluve. This is traced by the specifics of the technology of vessels production and their decoration. It is important to admit ceramic influences from Sofievskaya group populations in the Middle Dnieper region. Settlements which are chronologically similar to Hordashivka II in the Southern Bug and Dnieper interfluve are not numerous. Later sites in this area are not known, while Trypillia traditions continued in other regions. Keywords: Hordasivka-II, Late Trypillia (C II), settlements, houses, reconstruction, ceramics, chronology.

Full textAbstract:
Dnieper Left-Bank Forest-Steppe region in the Early Iron Age was inhabited in several stages. For the first time, the agricultural population appears in the Zhabotyn period. Settlements that emerged at this time would become the centres of some settlement structures in the Early Scythian period. There are no burial sites of the settled population of Pre-Scythian times in the basin of Vorskla and Psel rivers. The few burials of nomads of Pre-Scythian time are synchronous to this group of settlements with ashhills. These assemblages, except Butenky, have no signs of militarization of the population of the Post-Zrubna culture, which have left in the Forest-Steppe. It’s likely that these two groups of populations coexisted peacefully, occupying separate ecological niches.
The development of this population in relatively calm military and political conditions could have caused a demographic explosion and we have developed settlement structure in the middle of 7th century BCE. It represented by «cluster» of settlements with ashhills, which was united by a single burial mound necropolis.
Today, it may be considered densely populated territory between Vorskla and Psel rivers with an agricultural population from the Dnieper Right-Bank region in the Early Scythian time. At that time, nomadic groups are emerging in the region, some of which participated in Asia Minor campaigns. Their burial monuments are mainly identified at the routes of their movement and places of frequent stops (winterings, etc.) — the Sula river region, north-western Vorskla river region (Kup’ievakha, Kolomak). The appearence of the settlement at the place of Western fortification of Bil’sk hillfort Western fortification also connected with the fact that exactly nomads probably chose this strategic place as a wintering at the intersection of communications roads. Thus, the ethnical and cultural history of the Dnieper Left-bank Forest-Steppe of that time connected with close interaction of Vorskla river’ farmers with different groups of Iranian-speaking nomads, which were the decisive force in the region and had control over the settled population.

Full textAbstract:
The Muslim social movement known as the fergo Nioro provides a case of popular elaboration of the message of a leader of jihad. Umar Tal's call to holy war led to the conquest of Karta in the mid-1850s, and his call to hijra resulted in the migration of perhaps 20,000 Senegal-valley Fulbe to form a Muslim settler community. In the years after Umar's departure from Karta in 1859, military leaders and others in the Fulbe settler community sent envoys to recruit additional settlers from the Senegal valley. At least 16,000 and perhaps as many as 30,000 Fulbe responded to this recruitment effort and left Bundu, Futa Toro and the lower Senegal valley between 1862 and 1890. Two periods of more massive migration coincided with the residence at Nioro of Amadu Sheku, Umar's son and designated successor. During the late 1860s and early 1870s, a cholera epidemic swept up the Senegal valley, claimed thousands of victims, and encouraged Fulbe to leave the region for Karta. During the mid-1880s, French policies in the Senegal valley, notably the emancipation of slaves and moves to halt Fulbe raids in the lower Senegal valley, influenced the social movement.In both periods of large-scale migration and at other times, the Umarian envoys constructed an appeal which elaborated and even transformed Umar's call to hijra. Umar's insistence on holy war was a dominant theme in all periods, and resonated with the young men who left the valley in hopes of accumulating wealth through warfare. His condemnation of French influence in the Senegal valley was also expressed in the Arabic letters delivered by envoys. Umar's emphasis on the cutting of social bonds was not emphasized, as Fulbe settlers sought to attract relatives and neighbors to the new Fulbe communities in Karta.

The approaches to the use of catena method of studying the diversity of soil animal communities’ arena landscape of the Dnieper River Valley (within the natural reserve “Dnieper-Orelsky” using phytoindication estimation have been developed in the present article. Soil animals ecomorphes have been verified on the basis of main trends variability of environmental conditions which evaluated by means of phytoindication approaches. Monitoring polygon situated in the north-eastern part of the natural reserve "Dnieper-Orelsky". The width of the polygon is 3260 m, height – 2850 m, its total area is 930 hectares. Inside the polygon we selected some five plots: on the slope of the sand dunes at the border the sandy steppe and Acer tataricum shrub; on the slope of the Northern exposure of the Orlova valley in Acer tataricum oak forest with Dáctylis glomeráta; in terrace near the flood plain on the border with the lower part of the slope, in elm-black poplar forest with Glechóma hederácea; in the waterlogged tributary of river Protoch on the border of the marsh and forest ecosystems; in river Protoch in grass community, in a gradient from the marsh community to steppe meadows. Each plot was represented by 105 squares of size 3×3 m. Squares arranged in 7 contiguous rows of 15 squares in each. Plot size was 21×45 m. Big side plot was located along the visually discernible gradient terrain topography and vegetation cover. In each square we made a description of the vegetation with the assessment of the projective cover with a lag of 10%. In the center of each square we sampled soil of 0.25×0.25 m from which the soil macroinvertebrates have been extracted by hand sorting. The ordination of mesopedobionts communities has been applied to multidimensional scaling procedure based on metrics of Bray-Curtis with provisional data on transformation according to Hellinger. The phytoindication estimation of the environmental regimes have been found to be statistically significant predictors of multidimensional scales that obtained after ordination of mesopedobionts communities. Dimension 1 can be explained by edaphotop nutrient status, dimension 2 can be explained by edaphotop humidity, dimension 3 may be explained by soil aeration, dimension 4 may be explained by quantity of carbonates in soil. Dimensions 5 and 6 have a complex factor nature which is difficult to interpret meaningfully. Environmental assessment regimes using phyto-indicative scales enabled set the value of soil carbonate content and aeration in structuring of soil animals communities. The obtained result makes reasonable provision of new ecomorphes of soil animals such as aèromorph and carbonatomorph. Aèromorphes are ecological group that combines soil animals, preferring similar condition of soil aeration, among which are highlighted in aerophyles, sub-aerophyles, hemiaerofobes and subaerofobes. Carbonatomorphes are ecological group that combines soil animals, preferring similar condition of carbonates content in soil, among which are highlighted in carbonatofobes, akarbonatophyles, hemicarbonatophyles, carbonatophyles and hyper-carbonatophyles. Classic catena approach for biogeocenotic and landscape diversity investigation have been supplemented by the assessment of the ecological regimes through phytoindication and ecomorphic analysis of vegetation. Ordinates of ecological regimes are the gradients of variation of soil animal communities. Information and valuable markers of vegetation (phytoindication scale and ecomorphes) can be used as training variables to assess the indicator properties of soil animal communities. Ecomorphes of soil animals reflect the main aspects of the structural organization of their communities and may serve as valuable indicators of the properties and behaviors of soil as environment of living organisms.

The story of Tuzigoot National Monument, in Arizona’s Verde Valley, is that of a small town taking pride in its ancestral Native American history, securing funds from a mining company and the federal government to excavate a hilltop ruin associated with local tribes, and developing heritage tourism during the Great Depression. Its development, however, was dependent on military campaigns that drove Yavapai and Apache people on to the San Carlos Reservation. Today, despite evidence of environmental degradation caused by industrial-scale mining and smelting during the nineteenth and twentieth centuries, heritage and agritourism brings visitors to the area for wine tasting, bird watching, and kayaking. In an ironic twist, the Yavapai-Apache Nation now litigates to protect the health of the river on behalf of the communities who depend upon it.
