The monograph is devoted to methodological approaches in the study of fouling of various anthropogenic surfaces in the coastal waters of the southwestern shelf of the Crimean Peninsula. Attention is paid to the study of the effectiveness of various antifouling compositions with the complex use of physical, chemical and microbiological methods. The processes of biodegradation in seawater of organic components of various paint and varnish materials as a result of the vital activity of a community of peripheral microorganisms are considered. The possibilities of studying the fouling of various shipbuilding materials and structures in oceanic expedition conditions.

Preliminary studies of cultivated phytoplankton microalgae were carried out in water samples collected during four expeditions at oceanographic stations of the coastal waters of the northwestern and northeastern parts of the Black Sea in different seasons of 2019-2020. Some features of the development of the algological component in conditions of changing oceanological characteristics of the environment have been established. In spring, the most active growth of diatoms was revealed in the area from Balaklava to the water area of the Sevastopol Bay.

Barbus anatolicus, new species, is described from the Kızılırmak and Yeşilırmak River drainages in the southern Black Sea basin. It is distinguished from other Barbus species in the Middle East by having 58–71 total lateral line scales, a moderately ossified last simple dorsal-fin ray, serrated along about 70–80% of its posterior margin, many small irregular shaped black or brown spots, smaller or as large as scales, often forming large, dark-brown blotches on the head, back and flank in adults and juveniles, and a concave posterior dorsal-fin margin. In addition, DNA barcode data reject the hypothesis that it belongs to one of the other species of the B. barbus species group. Barbus bergi from Bulgaria and adjacent Turkey is treated as synonym of B. tauricus. Barbus tauricus was previously believed to be restricted to the Crimean Peninsula but is found to be widespread in the Black Sea basin.

Seascape complexes are decisive in choosing of technologies for growing different species of fish and mollusks, as well as in designing and installing farms on the Black Sea shelf. Marine farms, as hydrotechnical installations, play the role of artificial underwater seascapes and have a mutual influence on natural local systems. This article describes the main elements of mussel-oyster farms, the criteria for choosing a location for them, technological solutions of anchor systems, taking into account the peculiarities of the marine seascapes of the Crimean peninsula. In the Black Sea, it is advisable to install farms of the long-line type, which satisfy almost all the requirements for growing mollusks: they are quite stable during strong storms and wind impacts, allow changing the depth of mollusk placement if necessary, and are easy to install and maintain. The depths at the site which was selected for the installation of the marine farm should be in confines 10...30 m, and 15...20 m is the optimal depth for it. The permissible depth must be at least 10 m under the marine farm in consequence. The choice of optimal depths is associated with the need to save materials also. The characteristics, applicability and installation features of several types of anchors (concrete, screw and plow) for grounds of different composition and density are proposed. Promising areas for the development of the Black Sea mariculture are the western and eastern coasts of the Crimean peninsula.

The expansion of Oenanthe isabellina in Ukraine began at the end of 1950s - early 1960s. The Isabelline Wheatear settled along the coast of the Sea of Azov from east to west and appeared on the Crimean Peninsula later than in the regions located to the west of it. Since the late 1960s, this species has been nesting near the mouth of the Dnipro River which located in the west of the Crimean Peninsula. The nesting of Oenanthe isabellina was found in the northern part of the Crimean Peninsula in 1973. In the mid-1980s, the Isabelline Wheatear inhabited the northwestern coast of Crimea and appeared far in the east - on the Kerch Peninsula. In the southeastern part of the peninsula the range of the Wheatear reached the Black Sea coast by the end of the 1980s, when the species nesting was found near Feodosia. In the southeastern part of Crimea, the Isabelline Wheatear continued to settle along the Black Sea coast in a westerly direction in the 1990s: its nesting was found near Sudak. In the central Crimea, the species range reached the northern foothills of the Crimean Mountains at this time. The species expansion to the south slowed down by the beginning of the 2000s. In the western Crimea, the southernmost settlement of the Isabelline Wheatear was found near Evpatoria. In the northern foothills of the Crimean Mountains (Central Crimea), the range border has not changed. There were no significant changes in the southeastern Crimea during this period - in the 2000s, O. isabellina nested near Sudak as in the 1990s. The species expansion almost stopped in Crimea in the 2010s. The settling of the Isabelline Wheatear in the steppe regions of the southwestern Crimea did not occur, possibly due to the absence of little ground squirrel settlements, whose burrows birds usually use for nesting. The border of the O. isabellina range has moved southward on about 100 km for three decades - from the beginning of the 1970s to the beginning of the 2000s -, i.e. the settlement speed of the species in Crimea was about 3 km per year.

Abstract This article will explain why Russia annexed Crimea and is destabilizing eastern Ukraine. To do this, three different theoretical approaches on various levels of analysis will be used. It will be examined how far the expansion of NATO, as well as that of the European Union (Theory of Neorealism), was a motive for Russia’s action. NATO’s enlargement is analysed predominantly. In addition, politicalpsychological motivations of the Russian leadership are considered. But it is also analysed whether Russia’s pure power interests have played a role (Theory of Realism). The focus here is on the Russian naval base in Crimea. It is necessary to examine whether preserving its fleet in the Black Sea was a motive for Moscow to annex the Crimean peninsula.
