The article is devoted to the generalization of the existing information concerning dinoflagellates of the Crimea. A list of dinoflagellate species of continental waters of the peninsula and the Crimean coast (Black and Azov seas) of Ukraine was compiled. It is based on the analysis of literature and original data obtained in 1987, 1992-1993 and 2011 in the Black Sea. The list of dinoflagellata species of Crimea includes 196 species (206 infraspecific taxa) belonging to 64 genera, 36 families, 15 orders and 3 classes. Eighteen species have been recorded in the fresh and salt water bodies and mud volcanoes of the least studied continental part of Crimea; half of them were also found in marine waters. Dinoflagellates of the Azov coast of Crimea and the Kerch Strait are similar in number of species, but differ significantly in composition (26 and 31 species, respectively; only 13 (25%) of them are common). The greatest number of species of dinoflagellates found on the Black Sea coast of Crimea. It is almost half of all species known for the Black Sea (196 and 447, respectively). To compare the species richness of dinoflagellates from different regions of the Crimea, survey data covering all areas in a short period of time are of great importance. A total of 74 species of dinoflagellates belonging to 3 classes, 11 orders, 22 families and 30 genera were found off the coast of Crimea. The most species-rich genera are Protoperidinium Bergh (17), Dinophysis Ehrenb. (8), Gymnodinium F.Stein (7) and Prorocentrum Ehrenb. (6). Based on the analysis of original and literature data and the criterion of similarity of the species composition of Crimean dinoflagellates, it’s division into five algofloristic regions is proposed: the western Black Sea coast of Crimea (from Karkinitsky Bay to Cape Aya); southeastern (from Ayia to Takil), Kerch Strait, Azov coast of Crimea and land (which, in turn, is divided into steppe and mountainous Crimean regions). It is in compliance with the algofloristic zoning of Ukraine.

A one-apsidal hall church is always a reflection of so-called “vulgar” Christianity, thus revealing the important peculiarities of the spatial culture of the region where it is erected. In this region we can mark two periods when such temples were built: VI-VII c. and X-XII c. The first period is associated with the missionary activity by Byzantine Empire, Antioch, Caucasian Albania which was conditioned by both geopolitical interests (Byzantian Empire, Antioch) and the shift of The Great Silk Way to the north (Caucasian Albania). The second, as the research has shown, is connected with the migration of the peoples of Abkhazia, the abzakhs to this territory in the XII-XIII c. and the development of contacts with the Crimea. In the North Black Sea Region the one-apsidal hall church appears as early as in the VI c. – in the territory of Abkhazia we know about ten such temples. The temples of this type in the area of Big Sochi are dated back to the VII-VIII c. In the first Abhzaian temples we can reveal the influence of denominational centers – Byzantian Empire, Antioch, Caucasian Albania. In the temples of the Black Sea coast of both periods – introduction of the samples from Abkhazia.

The archaeology of the Black Sea coast quickly attracted attention when the Russians conquered the Crimea at the end of the eighteenth century, and the Scythic barrows of the Steppes began to be carefully excavated almost as soon; but it was not till the fifties and sixties that the less imposing antiquities of northern Russia found any one to study them even among Russians. West European interest naturally came later, the pioneers were first the Finn Aspelin in the seventies and next the Baron de Baye, who about 1890 sought to throw light from the East upon the Merovingian and other Teutonic styles which were his special province.

We present findings from the first survey of shallow-water amphipods conducted along the Black Sea coast in Georgia. Eight species from five families have been identified, all but one being new for the Georgian fauna. Although most are usual inhabitants of the Black and Mediterranean seas, we report the first record of the invader Melita nitida in this region. This North American species was previously known in Europe only from the Atlantic and Baltic coasts. Its finding in the Black Sea implies either jump dispersal, or a more widespread, but cryptic distribution. Given that the total number of species reported in Georgia is lower than in the other countries neighbouring the Black Sea, we anticipate the discovery of new taxa in future surveys. Our study highlights the importance of faunistic exploration in previously overlooked regions for detecting potentially cryptic invasions and corroborating biogeographical patterns.

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.

The paper examines the results of twelve-year (2007 to 2019) observations of spatial distribution and temporal changes in the concentrations of petroleum components in the coastal waters and sediment cores, as well as in the quantity and composition of oil slicks and tar balls on the beaches, cliffs and solid constructions of the Black Sea coast in the area of the city of Novorossiysk, which is the most important oil seaport of Russia, and in the Kerch Strait. 165 samples of seawater, 24 sediment cores up to 50 cm long split layer-bylayer into 108 samples, and 102 samples of oil slicks and tar balls were taken and analyzed with the use of thin layer and column chromatography, optical and gravimetric methods. The evidences of high level and chronic character of oil pollution of the studied coastal sectors are presented. Much attention is given to the dynamics of the natural transformation of oil slicks and tar balls found on the shore. It is shown that over time, under the influence of natural factors of attenuation, the oil slicks stranded ashore undergo an exponential decrease of the ratio between relatively labile hydrocarbons and conservative asphaltic components in their composition. The rate of the process may vary considerably depending on the size of oil pollution traces, their location on the coastal zone profile, as well as on the climatic, hydrological, and geomorphological conditions. An empirical statistical model is developed on the base of this data. This model makes it possible to classify and to map seacoasts according to their ability to degrade oil pollution using the information on the principal environmental parameters of attenuation.

Land Molluscs

At the end of the XX - beginning of the XXI century 85 species of the land molluscs of 49 genera and 25 families were reliably registered in the steppe zone of Ukraine. The highest species richness was recorded in the northern steppe subzone (79 species). The main centers of the species diversity are the Donetsk Upland (65% of the total number of species) and the western part of the Black Sea Lowland with the southern spurs of the Podolian Upland adjoining it (55%). The modern composition of the land molluscs fauna of the steppe zone is influenced by the proximity of the Caucasus (for the south-east of Ukraine), the Podolian Upland (for the north-west Black Sea coast) and the Crimea (for the entire investigated territory). Anthropochory plays an important role in the formation of the land molluscs complexes in the steppe zone of Ukraine.

Typical coastal elements of limans and lagoons are barriers, that separate limanic aquatories from a Seas. On limanic shores structure of the Black Sea sand barriers represented three longitudinal landscape “zones”: sea beach (“frontal”), dune-aeolian and limanic (“back of the barrier”). They closely interactive between themselves under influence of lithodynamical exchanges of sediment. General tendency of the barriers dynamics is displacement to Land direction.
