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.

This work is devoted to the analysis of the landscape structure of the coastal cliffs of the Black Sea coast of the Caucasus. The paper analyzes the features of vegetation growth and the landscape structure of the cliffs of the Tuaphat massif, proposes and substantiates the classification of landscapes of coastal cliffs, reveals the features of coastal landscapes. In the landscape structure of the coastal cliffs of the Tuaphat massif, natural boundaries can be distinguished by: the nature of the apparent occurrence of geological layers; substates by the steepness of the slope; striae, which are characterized by more abundant growth of vegetation along cracks in the geological layer; facies usually coincide geographically with nanoand microforms of the relief and are usually represented by one type of vegetation (for example, a pillow rock form). The distribution of vegetation by striae on fine crushed stone of siltstone or mudstone, the absence of halophytes, but the predominance of salt-tolerant plant species with a wide ecological amplitude (petrophytes, cosmopolitans and ruderal) are typical.

Brown marmorated stink bug Halyomorpha halys (Stål, 1855) is a highly aggressive crop pest that has appeared in Russia since 2014. Under the conditions of a new invasive species area, it is important to study the characteristics of the pest biology, including the study of the range of trophic plants. The studies were carried out in the zone of humid subtropics of the Black Sea coast of the Caucasus in 2014-2019. The study of trophic connections was carried out in the course of regular surveys of the region’s phytocenoses, including agrocenoses, landscape gardening and forest stands. During the observation period, the number of fodder plants of the brown marmorated stink bug was 107 species from 48 botanical families. The most diverse fodder plants of the Fabaceae, Rosaceae, Rutaceae, Sapindaceae and Solanaceae families. Among the food plants of H. halys, conifers are noted. It was Metasequoia glyptostroboides Hu & W.C. Cheng and Taxodium mucronatum Ten. Migration ways of brown marmorated stink bug from forest plantations to agrocenoses, gardens and city parks have been established. Such movements allows the pest to eat variably and to wait for adverse conditions.

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 analyses the corpus of documents from the fonds of the Russian State Military History Archive, formed in the 1830s during the General Staff officer Feodor Turnau’s expeditions of to the Black Sea coast zone, which lay outside the Imperial control. Although his activities among the Circassian tribes can be termed one of the best Russian secret scouting missions and his memoirs published in 1864 are still considered an important source for studying the military and political history of the region, materials and reports of the survey missions have never been examined in modern Caucasus studies. The author compares the data included by Turnau in his secret reports to the Imperial authorities with what he mentioned in his memoirs. It shows which issues the Imperial authorities and the Caucasus Army command were interested in during the Russo-highlanders confrontation of the second half of the 1830s. The materials collected by F. F. Turnau can be useful not only in terms of clarifying certain aspects of his personal activities, but also in demonstrating the running of secret survey scouting in unexplored and dangerous ethnic territories off the Imperial frontier. They show high erudition and good training of the candidates selected from the ranks of the General Staff officers to run these scouting missions. The correspondence of the Caucasus Army commander with the central authorities in St. Petersburg on the issue of Turnau’s captivity shows differences in their understanding of the Russo-Caucasus relations. The author comes to the conclusion that the corpus of collected materials on topography, ethnography, political and cultural description of the Transkubanian region peoples could have formed a basis for a revision of the Imperial stand on the subjugation of tribal groups. Although this political alternative was missed, the materials collected by Turnau became a precious addition to the Caucasus studies source base.

Влажные субтропики Черноморского побережья России являются региономреципиентом для большого количества инвазионных видов вредных организмов. В начале XXI в. в зоне влажных субтропиков России выявлены 35 новых видов дендрофильных насекомых, из которых 26 можно отнести к инвазионным: из них 17 видов новые для территории России, а 9 новые для субтропической зоны Черноморского побережья Кавказа. Особенности инвазионного процесса у фитофагов изучались на основе анализа таксономического состава, регионовдоноров, векторов и путей инвазии, биотопического распределения видов и динамики инвазий. За период 2000 2017 гг. в общем количестве появившихся инвазионных видов отмечено снижение доли представителей отряда Hemiptera и увеличение доли представителей отряда Lepidoptera. В последние годы наибольшее количество инвазионных видов вредителей имеет североамериканское, а не восточноазиатское происхождение, что было характерно для региона на протяжении предыдущих полутора столетий. Установлены векторы инвазии для новых видов: непреднамеренный завоз с посадочным материалом, проникновение с транспортными потоками, непреднамеренный завоз с грузами нерастительного происхождения, самостоятельные перелеты. Все инвазионные виды восточноазиатского, американского и австралийского происхождения характеризуются двухступенчатой инвазией, т. е. они проникали в Россию из вторичного ареала в Европе. Максимальное количество чужеродных видов обосновалось в насаждениях декоративных пород (садовопарковые экосистемы), причем эта тенденция традиционна для региона. Частота появления инвазионных видов на Черноморском побережье Кавказа в начале XXI в. 1 вид в 9 месяцев, что в 7,4 раза чаще, чем в начале XX в. Humid subtropics of the Russian Black Sea coast are the recipient region for many invasive species of harmful organisms. At the beginning of the XXI century, 35 new species of dendrophilous insects were identified in the humid subtropical zone of Russia, 26 of which can be considered invasive: 17 species are new for Russia and 9 are new for the subtropical zone of the Black Sea coast of the Caucasus. Special features of the invasive process among phytophages were studied using following parameters: taxonomic composition, donor regions, vectors and pathways of invasion, biotopic distribution of the species and invasion dynamics. During the period of 2000 2017, a decrease in the representatives of order Hemiptera and an increase in the representatives of order Lepidoptera has been recorded. In recent years, the largest number of invasive species has North American origin rather than East Asian, which was typical for the region over the previous one and a half centuries. The following invasion vectors were specified for the newly recorded species: unintentional importation with planting material, invasion with traffic flow, unintentional importation with goods of nonplant origin, independent migration. All invasive species of East Asian, American, and Australian origin are characterized by twostage invasion, namely arriving to Russia from the secondary invasive range in Europe. The maximum number of alien species has settled in the plantations of ornamental species (landscape ecosystems), and this trend is traditional for the region. The rate of invasive species on the Black Sea coast of the Caucasus in the early XXI century was once in nine months, which is 7,4 times higher than in the early XX century.
