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.

A survey and revision of the highest syntaxa of the class Onosmato polyphyllae—Ptilostemonetea Korzhenevsky 1990 of the Crimean peninsula is made. Syntaxonomic position of the lowest syntaxa of the petrophytic communities recorded from the Black Sea coast of the Caucasus in system of units of this class is determined.

A new species of the genus Cimmerites Jeannel, 1928, C. maximovitchi sp. nov., is described from the Akhunskaya Cave and Labirintovaya Cave, both located in the Akhun Karst Massif on the Black Sea Coast of the West Caucasus (Krasnodar Territory, Russia). The new species is rather isolated within the genus Cimmerites and occupies an intermediate position between species related to C. kryzhanovskii Belousov, 1998 and species close to C. vagabundus Belousov, 1998. Though both C. maximovitchi sp. nov. and C. kryzhanovskii are still known only from caves, these species are quite similar in their life form to other members of the genus which are all true endogean species.

The status of breeding pelicans and cormorants is assessed in the area from the Danube delta (Romania) to the northern part of the Crimean peninsula. Four breeding species occur in inland and coastal wetlands: Dalmatian Pelican Pelecanus crispus, Great White Pelican Pelecanus onocrotalus, Great Cormorant Phalacrocorax carbo and Pygmy Cormorant Phalacrocorax pygmeus. Data on clutch size and breeding success are given. Historically, all four species were restricted to the Danube delta. Currently, with the exception of Dalmatian Pelican, they all breed successfully on the eastern Black Sea coast in the Ukraine. There are many conservation problems that will jeopardize the breeding of these species in the future if nothing is done.

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.

Mithridates II was succeeded by his ephemeral son, Mithridates III, and then by 220 BC his son, Pharnakes I, was on the throne. He was a powerful and aggressive monarch who ruled for over thirty years and greatly expanded the territorial extent of the kingdom. He lived in an era of great change in the Hellenistic world, as the Romans began to become involved in the destinies of the eastern Mediterranean states: Pharnakes reached out to the Romans in the 180s BC concerning territorial disputes in Asia Minor. He engaged in war with his powerful neighbor to the west, Pergamon, but was forced to sign a peace treaty not to his advantage. Yet he expanded Pontic territory along the Black Sea coast and made several alliances with the Greek cities on the northern and western coast of the sea, especially in the kingdom of Bosporos (modern Crimea).

Abstract Firths are geomoiphological and hydrological sites typical for flat, neutral coast of no tidal sea basins. There in the greatest extend is preserved the geological column of the correlative Pleistocene- Holocene sediments. They make possible to reveal the Quaternary evolution of the contact zone „land-sea“. Firths are one of the most reliable indicators for the Quaternary Earth crust movements. Along the Black Sea coast most widely are developed the firths in the north - west and the west periphery, where they form a classic firth type coast. This report examines the results of complex studies of Batova river firth, located (developed) on the North Bulgarian Black Sea coast.

Holocene fluctuations of the Black Sea level have played a significant role in the existence of the Black Sea polis-cities. The high sea-level during the Novochernomorian transgression is followed by the Phanagorian regression when the sea level reached its minimum of 3 m below the modern sea level during the antiquity (Roman Age). Then, on the west coast of Mandra Lake the Roman polis Deultum was founded which became a flourishing port. The discrepancy between the low sea level and ancient navigation activity in Mandra Lake is a challenge for further investigations of the Holocene sediments.

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.
