Abstract The research on archaeological materials from sites 11, 15, and 20 at Święte produced a series of 13 radiocarbon dates for niche graves of the Corded Ware culture (CWC). The results are coherent and point to a range of 2550-2350 BC. This corresponds well with other results obtained for nearby CWC cemeteries in the Rzeszów Foothills, and is consistent with dates obtained for CWC graves in other regions in Lesser Poland: the Lesser Poland Upland, the Sokal Ridge, and the Lublin Upland. At the same time, the obtained absolute age range corresponds with a wave of influences from the North Pontic circle of steppe cultures and the Middle Dnieper culture. It can be synchronized with the beginning of the development of the classic variants of the Catacomb culture: the Ingul and Doniec variants.

The year 2014 marked the 160th anniversary of the beginning of the Crimean War, 1854–6. It was during that anniversary year that the names of Crimea, Sevastopol, Simferopol and the Black Sea re-entered the lexicon of Ireland, and so did the terms ‘Russian aggression’, ‘territorial violation’ and ‘weak neighbour’. Coincidentally, those same places and terms, and the sheer extent to which they perpetuated within Irish and even world media as well as popular parlance, had not been seen nor heard since 1854. It was in that year that the British and French Empires committed themselves to war in the wider Black Sea region and beyond against the Russian Empire. The latter had demonstrated clear aggression, initially diplomatic and later military, against its perceived-to-be-weak neighbour and long-term adversary in the region, the Ottoman Empire, or Turkey. As part of that aggression Russia invaded the latter’s vassal principalities in the north-western Balkans, namely Wallachia and Moldavia (part of modern-day Romania), collectively known as the Danubian Principalities. Russia had previously taken Crimea from the Ottomans in 1783....

AbstractThe heritable elytral colour/pattern polymorphism of Philaenus spumarius in north-western Black Sea region of Turkey was investigated. A total of 2,530 adult spittlebugs, 1,020 females and 1,510 males were collected and analysed in terms of the 11 most common colour forms. Nine different phenotypes, expressed by six different alleles, were determined: populi (POP), typicus (TYP), trilineatus (TRI), marginellus (MAR), flavicollis (FLA), leucocephalus (LCE), gibbus (GIB), albomaculatus (ALB), and leucophtalmus (LOP). The common phenotypes lateralis (LAT) and quadrimaculatus (QUA) of previous studies were not encountered at all. The predominant phenotype was TYP (63%) in females and males followed by POP (31%). TRI (4%) and melanics (5%) were at close proportions. However, only one site had nine phenotypes altogether. The majority of the sites had only the POP and TYP morphs. The melanic forms were found only in females.

Many years’ studies of process of changes in composition, properties and fertility of the black soils of the North-Western Black Sea area in Ukraine with irrigation have revealed mobility of carbonates and humus in them, decrease of capacity of cationic consumption and content of consumed calcium, increase of share of consumed magnesium and sodium. Indicators of agro-physical state of soils under irrigation conditions are worsening significantly.

The article presents a complete mathematical formulation of the problem of the boundary layer of the atmosphere and the interacting surface layers of the soil with the active layer of the sea adapted to the North-Western Black Sea Region through the inclusion of the coastline shape, relief elevation angles and climatic characteristics of soil moisture. The numerical model is a three-dimensional, unsteady, hydrostatic model with one- or two-parameter closure. The paper presents a detailed description of the applied sub-grid processes parameterizations such as cloudiness in the lower tier, flows of short- and long-wave radiation throughout thickness of the boundary layer and near the Earth, antigradient migration for basic meteorological variables in the presence of neutral or weakly stable stratification, components of water, heat and radiation balance, phase transitions of moisture in the atmosphere, and different parameterizations of turbulent processes used in the model. The possibilities of the model include description of neutral and stable boundary layers with consideration of the kinetic energy of vertical velocity fluctuations instead of the kinetic energy of longitudinal and transverse velocity fluctuations. Identification of the type of the boundary layer at a particular point in time is estimated using values of the Richardson number. In addition, in case of convective conditions presence, parameterization of dry convection and wet-convective adaptation may be implemented. At the boundaries of "free boundary layer – surface or near-water layer of air, air-soil and air-water" certain bonding conditions are to be set to ensure continuity of meteorological parameters or their flows. On the upper boundary of the free boundary layer actual values of meteorological parameters and necessary parameters, or corresponding values from the global atmospheric model are to set. At the lower boundary of the deep soil layer the invariance of the vertical temperature gradient of the active layer of the sea – the value of temperature which is equal to the value of the latter according to its climatic values in the considered season of the year is to be set. The presented model is the first approximation in numerical modeling of the boundary layer over the adapted territory and is designed for studying the thermodynamic structure of the boundary layer of the adapted territory, as well as for identifying the breeze effects over the terrain.

The article presents the results of research on the species diversity of algae of small steppe rivers of the north-western Black Sea coast (NWBS). These are the rivers of Kohylnyk, Chaha, Sarata, Hadjider, Kuchurhan, Yahorlyk, Baraboy, Veliky Kuyalnik, Maly Kuyalnik, Kodyma, Tylihul, Tsarehol, Chichikleya. A total of 329 species (340 infraspecific taxa) of algae belonging to 8 divisions (Bacillariophyta, Cyanobacteria, Chlorophyta, Euglenozoa, Ochrophyta, Charophyta, Dinophyta and Rhodophyta) were identified. The basis of the taxonomic structure of reservoirs are representatives of Bacillariophyta (40%), Cyanobacteria and Chlorophyta (17% each), Charophyta (10.5%), Euglenozoa (10.2%). The total share of other departments is 4.1%. The Tylihul River had the most diverse composition of algae. It is one of the largest small rivers in the region, which dries up every year for a short period. According to the Sørensen-Chekanovsky coefficient, the greatest degree of similarity of the floristic composition of algae was established by pairwise comparison of the rivers of Sarata–Kohylnyk (0.614), Sarata–Hadjider (0.544), and Kohylnyk–Hadjider (0.517). These reservoirs are located in the Danube–Dniester interfluve, have almost the same mineralization and a similar hydrological regime. Among the identified algae species, only 12 are common to all studied rivers. New records for the NWBS were Peranema pleururum Skuja, Phacus platyaulax Pochmann, Monomorphina pyrum (Ehrenberg) Mereschkowsky and Euglena van-goori Deflandre. A rare species Spirulina flavovirens Wisl. was found in in the Kohylnyk River. Anabaena bergii Ostenfeld, Phacus alatus G.A.Klebs, Monomorphina pyrum, Pleurosira laevis (Ehrenberg) Compère, Campylodiscus bicostatus Smith ex Roper, Closterium dianae Ehrenb. ex Ralfs and Batrachospermum gelatinosum (Linnaeus) De Candolle are regionally rare species. In the ecological aspect, the waters of the studied small rivers can be characterized as brackish, poorly flowing, and alkaline. According to the level of organic pollution, they correspond to the β-mesosaprobic zone.
