Molecular biogeography of the fungus-dwelling saproxylic beetle Bolitophagus reticulatus indicates rapid expansion from glacial refugia

Abstract The geographical distributions of species associated with European temperate broadleaf forests have been significantly influenced by glacial–interglacial cycles. During glacial periods, these species persisted in Mediterranean and extra-Mediterranean refugia and later, during interglacial periods, expanded northwards. The widespread saproxylic beetle Bolitophagus reticulatus depends closely on European temperate broadleaf forests. It usually develops in the tinder fungus Fomes fomentarius, a major decomposer of broadleaf-wood. We sampled B. reticulatus in sporocarps from European beech (Fagus sylvatica) and Oriental beech (Fagus orientalis) across Europe and the Caucasus region. We analysed mitochondrial gene sequences (cox1, cox2, cob) and 17 microsatellites to reconstruct the geographical distribution of glacial refugia and postglacial recolonization pathways. We found only marginal genetic differentiation of B. reticulatus, except for a significant split between populations of the Caucasus region and Europe. This indicates the existence of past refugia south of the Great Caucasus, and a contact zone with European populations in the Crimean region. Further potential refugia might have been located at the foothills of the Pyrenees and in the Balkan region. Our genetic data suggest a phalanx-wise recolonization of Europe, a reflection of the high mobility of B. reticulatus.

Migration factors as a reflection of the state of society (analysis of migration process in the Republic of Crimea)

The author has made an attempt to determine the stimulating and restraining factors influencing both the dynamics and specifics of migration processes on the Crimean Region. The events of the Crimean spring have served as a key trigger of migration both to and from Crimea and in this sense the individual story of a migrating person allows for a deeper understanding of the reasons why people decide to leave Crimea or move to this region. This is the reason for the choice of the case-study method. The author systematizes the factors of migration. First of all, the factors of migration are divided into natural and social. All identified factors are divided into two large groups: stimulating and restraining. Among the stimulating factors natural factors prevail: climate, proximity to the sea, ecology and beautiful landscapes. It is important to note that they are joined by only one socio-cultural factor of migration: mental proximity and assessment of the prospects of the Crimean society in all its dimensions. Also all the stimulating factors are related to the current situation in Crimea. Among the restraining factors of migration the factors of social nature are predominant. They both arise in various spheres of social life and transform them. These include high prices for food, rent and purchase of real estate, services in the commercial sector, as well as sanctions and political and economic isolation. The restraining and stimulating factors of migration processes reflect both the problem areas in society and the directions of development.

Selenium status of urban residents on the territory of the Crimean peninsula

Introduction. Considering the essential biological role of selenium, including its role in preventing cardiovascular diseases and its widespread deficit in soils, assessing selenium status for Crimean region inhabitants is an actual task. Material and methods. Determination of selenium content in hair as index the of long-term element’s intake into the human body by all pathways were determined by the fluorometric method in 46 inhabitants (18-20 years old) from city Simferopol. Additionally, the selenium was determined in water and food products in Simferopol and nearby residential territories. Results. Selenium content in most residents’ hair varied from 210 to 309 mcg/kg and 12-40% less than the normal range’s lower limit. These results show the selenium deficiency in urban residents from the Crimean region, mainly due to the low content of this element in cereal products and, to a less degree, - in water. However, most food products, which are the primary source of selenium in Crimean inhabitants’ diet, are delivered from other Russian regions. So it’s possible to assess the selenium supply of inhabitants, but it is not possible to make a total conclusion about the selenium status of the region. Conclusion. The revealed deficiency of selenium in Crimean region inhabitants and the literature data about the positive and close relationship between hyposelenosis and the quality of public health requires the extensive monitoring of the selenium content in soils and crop production the Crimean peninsula territory.

Geoelectrical inhomogeneities of the Crimean region as the seismicity and oil-gas potential zones

The three-dimensional geoelectrical model of the Earth’s crust and upper mantle of the Crimean region and adjacent territories has been built for the first time. It is based on the results of the Earth’s low-frequency electromagnetic field experimental observations, conducted in 2008—2013 by the Institutes of the National Academy of Sciences of Ukraine. The subvertical conductive zones or contacts of the different resistivity mainly in the near-surface layers coincide with the fault structures, most of which are confined to the boundaries between the different tectonic elements, such as the Scythian Plate and Mountain Crimea, North and South Kerch Zones and the other faults: Chongarskiy, Melitopol-Novotsarytsynskiy, Korsarsko-Feodosiyskiy, Gornostaevskiy and Kerch-Chkalivskiy. The Mykolayiv and West Crimean fault systems occur as large separate submeridional conductive zone. Deeper in the Earth’s crust and upper mantle, geoelectrical inhomogeneities are transformed into the subhorizontal structures (layers) and manifest themselves in regional anomalies. This fact may indicate the high permeability for deep fluids of contact zones during their formation. The deep sublatitudinal structure in the Earth’s crust is confidently traced, in the west it confirms and details the well-known Tarkhankut anomaly, and continues through the central Crimea to the northwestern part of the Kerch Peninsula. It is assumed that there is the strong sublatitudinal anomaly in the interior of the northwestern shelf of the Black Sea and in the northeastern part of the Kerch-Taman Depression at the crust — upper mantle boundary, it is contouring the Crimean Peninsula. The ultradeep fluid manifestation zones obtained according to seismotomography, the conductivity anomalies in the Earth’s crust and the upper mantle, increased heat flow and the spread of the earthquake hypocenters confirm the relationship between the Crimea seismicity and collision processes. It is shown the spatial coincidences of the hydrocarbon manifestations and the isolated conductivity anomalies, which are characterized by subvertical channels galvanically connected to sediments, or subvertical contact zones of different resistivity, which are observed not only in the Earth’s crust but also in the upper mantle layers (60—90, 110—140 km) and may cause the superdeep fluid inflow.

РАЗВИТИЕ ШЕРИНГОВОЙ ЭКОНОМИКИ КАК СРЕДСТВО СНИЖЕНИЯ СЕЗОННОСТИ В ТУРИЗМЕ

The relevance of the topic is due to the need to solve the scientific problem of substantiating the theoretical and methodological foundations of the development of shering economy as a form of interaction of business structures. The purpose of the article is the theoretical justification, the development of scientific and methodological approaches and practical recommendations for the development of the shering economy in the Republic of Crimea. The subject of the study is the shering economy as a new economic model. An analysis of the types of shering developed in the Crimean region was carried out. The reasons that caused seasonal fluctuations in the tourism and recreational sphere of the Crimean region were determined, and the negative impact of seasonality on the functioning of the tourism and recreational sphere was also considered. The article provides a justification for the prospects for the development of one of the forms of sharing economy - colivating - in the Republic of Crimea. The advantages of the development of the shering economy include: great opportunities for small entrepreneurs, more efficient use of resources, organization of additional jobs, increased speed of searching for the necessary goods and services, and greater choice, no need for personal contact, positive impact on the environment, the creation of a new quality control system based on consumer feedback, developing social ties in the process of finding the right things and services. The work proposed to use cottage villages and miniboarding houses located in the region for colivings. Comparative characteristics of different temporary means of accommodation are given. The practical significance of the results is that the developed provisions and recommendations can be used by entrepreneurial business structures in the tourism and recreation sector to reduce the seasonality of functioning.

Том “Луганська область” енциклопедичного багатотомника “Історія міст і сіл Української РСР”: особливості підготовки

The paper deals with problems and process of preparation of the “Luhansk Region” volume as part of the unique encyclopedic project “The History of Cities and Villages of the Ukrainian SSR” in 26 volumes. The study is based on the documents of the central Ukrainian archives. The author focuses on the fact that due to the coordinated professional work of the regional executors of the project, the volume was prepared in a very short terms compared with the overwhelming majority of the volumes on other Ukrainian regions. After all, starting from 1967 to 1968 only 5 from the 26 volumes (that were planned according to the “On the publication of the history of cities and villages of the Ukrainian SSR” Decree of the Central Committee of the Ukr. SSR Communist Party on the May 29, 1962) were published. In addition, the publication of all the volumes had to be devoted to the 50th anniversary of the “Great October” (November, 7, 1967). It is worth emphasizing that initially the Main editorial board of the project did not considered the “Luhansk Region” volume to be among first volumes to be published. However, in the preparatory process, the order and timing of the publication of volumes differed from the planned due to various objective and subjective reasons, and the last book of the Ukrainian-language version of the project, namely the “Crimean Region” volume was published in 1974 only. The author on the example of the Luhansk volume creation has showed the character of that reasons. They were uncovered at the meetings of the “History of cities and villages of the Ukrainian SSR” Main editorial board and of the “History of cities and villages of the Ukrainian SSR” department of the Institute of History of the Ukr. SSR Academy of Sciences during discussions on various stages of the volume creation and scientific problems regarding the writing of texts. The positive role of the State Archives of the Luhansk region’s and the regional editorial board’s management in its preparation has been highlighted. The difficulty to create both the introductory article and essays about the settlements of the region was that it was formed from the territories that had been previously parts of other regional entities. Therefore, the authors not only studied a large number of literature, including the pre-revolutionary, but worked a lot in various Ukrainian and Russian archives to collect information. It happened due to the organizational support and promotion of the regional party Committee that seriously attributed to the intensive and successful process of the volume preparation.

ИСПОЛЬЗОВАНИЕ ФОТОЭЛЕКТРИЧЕСКИХ МОДУЛЕЙ С ДВУХСТОРОННЕЙ ПРИЁМНОЙ ПОВЕРХНОСТЬЮ ДЛЯ УСТАНОВОК МАЛОЙ ГЕНЕРАЦИИ

In the presented work, the possibility of using photovoltaic silicon panels with a double-sided arrangement of solar cells on the front and back sides is presented. With a lack of space for placing solar panels, these types of modules can significantly increase the generation of electrical energy. Equipping photovoltaic systems with rechargeable batteries contributes to a more rational consumption of electrical energy, while energy storage systems significantly increase the efficiency of solar generating systems. The proposed designs are intended to increase the power characteristics of solar energy converters in the winter months, in the presence of snow or when using reflective surfaces on road surfaces. The results of the experimental studies have shown a significant efficiency of the proposed designs, as well as an increase in the total generation of electrical energy. With the development of the global technical potential and a significant increase in the production of power plants for solar energy, a new opportunity has emerged to use combined solar plants for photovoltaic conversion of the flux of incident solar radiation. At the Department of Renewable Energy Sources and Electrical Systems and Networks at Sevastopol State University, at the site of the Institute of Nuclear Energy and Industry, a photovoltaic installation was developed and studied, consisting of two side silicon solar cells and energy storage systems. The article presents the results of experimental and theoretical studies, presents diagrams, drawings and graphs of various characteristics of the FSM-110D photovoltaic panel and storage batteries. The research results show the increased efficiency of the proposed installation, as well as a good possibility of using the presented photovoltaic systems to provide them with autonomous and individual consumers living in the Crimean region and the city of Sevastopol.

ОЦЕНКА НЕФТЕГАЗОВЫХ ПЕРСПЕКТИВ КРЫМСКОГО ПОЛУОСТРОВА КАК РЕЗУЛЬТАТ ГЕОДИНАМИЧЕСКОГО МОДЕЛИРОВАНИЯ ЗОНЫ СУБДУКЦИИ ВОСТОЧНО-ЧЕРНОМОРСКОЙ ПЛИТЫ ПОД ЛИТОСФЕРУ СКИФСКОЙ ПЛИТЫ

In this article, based on the data on the convective heat transfer from the mantle wedge to the 2D heat flow anomaly observed in the rear of the Central Crimean arch, the angle of inclination of the mantle wedge and the rate of subduction of the East Black Sea lithospheric plate under the lithosphere of the Scythian continental plate (Crimean region) are estimated. The effects of the 410 km and 660 km phase transitions are taken into account. Within the framework of the geodynamic model constructed the horizontal extent of the 2D heat flux anomaly observed in the rear of the Crimea mountain belt corresponds to subduction velocity of ~ 40 mm per year which is close to that observed with the help of geodetic means. Ascending convective movements in the mantle can carry mantle calcareous-alkaline magmas (with hydrocarbon geo-fluids contained in them) into the near-surface layers of the Earth’s crust, and, consequently, oil and gas fields should be confined to zones located in the upper part of the lithosphere, above the convective vortices of the Karig.

Опыт картографирования Крымского регионального рынка СМИ

The article describes the geographical approaches to the study of mass media. The main directions of mapping the media sphere are defined and described: maps of the development of telecommunications infrastructure, maps of media production, maps of population provision and availability of media products, cartographic technologies in media activities, mapping of mass information and big data. The essence of the concept of geographical media market is considered. The research interest of this paper is focused on mapping traditional media, namely regional newspaper publications and television channels. The methods of mapping and geographical segmentation of the regional market of newspaper publications and television media are described and tested on the example of Crimea. The article presents cartographic works that reflect the territorial differentiation of local newspapers and their sales, the level of development of digital television broadcasting infrastructure, and the nature of localization and scope of local television activities in Crimea. The article describes the segment of national and religious mass media, which are an important element of the social development of the polyethnic and polyconfessional Crimean region. The geographical segmentation of the print and television media market of the Republic of Crimea and the federal city of Sevastopol was performed. As a result, the main media centers, acceptor-creative and acceptor territories were identified. The use of the cartographic method allowed us to identify the type of territorial structure of the geographical media market of Crimea. It is concluded that this area of activity in the region develops according to the “center–periphery” model, which is complicated by the split in the level of telecommunications development in the “city–village” direction. Despite a fairly extensive network of media enterprises in Crimea, a number of cities and districts do not implement the potential for creating local media on their territory.

The development of network interaction of specialized organizations is proposed, the advantages of the network principles of functioning of the recreational and rehabilitation distributed consortium, stimulating the development of new directions of medical and rehabilitation services, are determined.

ІНТЕРПРЕТАЦІЯ 3D ГЕОЕЛЕКТРИЧНОЇ МОДЕЛІ НАДР СТЕПОВОГО КРИМУ. ЄВПАТОРІЙСЬКИЙ ТА САКСЬКИЙ ПРОФІЛІ

The interpretation of the segment of the deep three-dimensional Crimean region geoelectrical model within the Saki and Yevpatoria profiles, built on the basis of the Earth's low-frequency electromagnetic field experimental observations, was obtained in 2012 by the INSTITUTE OF GEOPHYSICS named after S.I.Subbotin. The main result of the analysis is the identification of vertical and horizontal alternation of high and low resistivity, both in the earth's crust and in the upper mantle. It is shown that the geoelectrical sections along all the profile sections of the model are characterized by a dip to the north of the consolidated basement surface depth and, accordingly, an increase of the near-surface layer conductivity. The conductivity anomaly in the consolidated earth's crust was revealed in the depth interval of 5-10 km with resistivity (ρ) of 5 Ohmꞏm, galvanically connected with the sedimentary cover. Deeper than 10 km, homogeneous and inhomogeneous layers in ρ alternate: 10-60 km with ρ = 1000 Ohmꞏm; 60-90 km with ρ = 100 and 1000 Ohmꞏm; 90-110 km with ρ = 1000 Ohmꞏm; 110-140 km with ρ = 40 and 1000 Ohmꞏm, the contact corresponds to the different ρ of normal geoelectrical sections of different-aged structures of the Scythian plate and the East European platform; also horizontally layered normal section. It has been analyzed that earthquake sources of the Steppe Crimea seismic region are concentrated in geoelectrically inhomogeneous zones and tend to contact structures with ρ differ - above the upper margin, outside and between the conductivity anomalies in the consolidated rocks of the earth's crust. The considered material confidently indicates the confinement of hydrocarbon manifestations to the high electrical conductivity anomalies identified according to the data of geoelectromagnetical sounding and three-dimensional modeling, which are characterized by subvertical channels galvanically connected with sedimentary deposits, and layering in the earth's crust and upper mantle. Geoelectrical inhomogeneities, which reflect the current state of the earth's crust and upper mantle and are probably due to the influence of modern mantle fluids, correspond to manifestations of seismicity and hydrocarbon content.

Опыт картографирования геополитических аспектов устойчивого развития Крыма

The article considers the methodology of cartographic study of geopolitical risks in the border region of the Black Sea region—Crimea. Geopolitical risks are presented as one of the options for potential constraints on the sustainable development of Crimea. Geopolitical risk refers to the situation of uncertainty that arises in the region in the process of changing its political subjectivity. The program of a cartographic study of geopolitical risks in the region was proposed. It includes stages of exploration and mapping long-term dynamics of their manifestation in the region; identification of cause-and-effect relationships and mutual conditionality of factors of occurrence of geopolitical risks; forecast of socio-economic development and geopolitical risks in Crimea for the near and distant future; justification of the strategy of socio-cultural development of the Crimean region and preventive actions in the system of management of geopolitical situations. The results of the first stage of the study of geopolitical risks in Crimea are presented. A map of the dynamics of ethnic and confessional contradictions in Crimea in the period 1990–2015 is developed. An understanding of the contradiction as a stage of pre-conflict with the potential for peaceful resolution, but not overcome in content, is proposed. The localization of ethnic and confessional contradictions in the Crimea is analyzed. The regions and spatial foci of their concentration are determined. The emergence of ethnic and confessional contradictions in regions with increased ethnic mosaic is proved. A map of the geopolitical risks in Crimea that emerged after 2014 has been developed. The transformation of the types of geopolitical risks in Crimea is analyzed. It is noted that the possibility of the emergence of ethnopolitical contradictions and their addition to the risks of information manipulation of information about the region in the media, as well as the emergence of risks of terrorist activities on the territory of Crimea. The conclusion is made about the spatial asymmetry of the localization of geopolitical risks in Crimea. A significant part of the geopolitical risks is localized in those regions of the peninsula that concentrate the economic and informational attractiveness.

Crimea in the Space of Soviet Everyday Culture

An analysis of the main stages in the evolution of ideas about Crimea as the main Russian and Soviet resort — from the end of the 19th century to the late Soviet period — is the focus of this paper. Tavrida, the Crimean Republic, and then the Crimean region created a canon of perception of this place — fragments of ancient civilization, “Red Nice” or a real all-Union health resort for all residents of the Soviet Union. It was necessary to fill the Soviet space outside Crimea with signs that represent the history of Crimea and the new Crimean recreational reality for this canon to become an element of everyday culture. These were reflections of history and culture in works of fine and decorative art, industrial design, souvenirs, as well as objects that record memories of a trip to Crimea.

Reconstruction of the economy of the southern regions of the Ukrainian SSR and socio-economic revival of Crimea after the Second World War

The research has provided an analysis of the social and economic situation on the Crimean Peninsula after the end of the World War Second, as well as on the territory of Ukrainian SSR neighboring to it. The obtained data as regards the situation with the economy and manpower resources of Crimea after the end of military operations and expulsion of indigenous peoples on its territory, as well as the social and economic situation of Kherson region and east regions of Ukraine provided the basis on which the main conditions of economic recreation of the Crimean region were studied. The materials were analyzed based on archive funds including business correspondence and statistical data of the state authorities in Ukrainian SSR and in the governing party (Ukrainian Communist Party of Bolsheviks) the bodies of which actually took all principal management decisions. The research showed that significant manpower and material resources were activated in southeast regions of Ukraine with the purpose of implementing large-scale projects in the industry and agriculture. The biggest at­tention was paid to development of power generation based on coal mining in Donets Basin and heat power generation in Dnipro Basin. Formation of powerful energy areas created conditions for development of systems for irrigating arid land in south regions of Ukraine, electrification of agriculture and formation of powerful industrial clusters in those regions of Ukraine that were neighboring to the Crimean Peninsula. Realization of large-scale projects of development in the regions, which were neighboring to territory of Crimea during the years of the first five-year plan implementation after the end of the World War Second created conditions for the economic recreation of Crimea through applying the experience and extend­ing the territory scope of projects implementation to the territory of peninsula.

Values and Regulations of Journalism as Viewed by Crimean Media Workers

Crimean journalists’ professional community has been working in a specific context during the recent six years. The journalists have had to adapt to the new political, legal and socio-cultural realia. Besides, they have had to work under the international sanctions imposed on the Crimea. Due to the increased attention of Russian society to the region, the community of Crimean journalists has successfully assimilated into Russian media landscape. However, its problems and characteristics, particularly, their vision of professional values and legal regulations, still remain unstudied. The purpose of the article is to study Crimean media workers’ perception of social functions of journalism, its ethical norms and legal regulations, and freedom as a basic category and value. The study required conducting a survey that involved 95 journalists from 56 editorial offices in 20 locations in the Crimea. The respondents demonstrate a clear understanding of values and regulations of their profession and view informing the public about the events in the Crimean region as the key journalists’ role. They are convinced, in this relation, that the most important ethical principle is their audience’s right for true information. The respondents also consider Russian legal regulations a key pre-requisite for their professional freedom – free search for and distribution of information. The author infers that Crimean journalists have enough freedom to perform their professional functions.

Динофлагеляти Кримського півострова та його морського прибережжя

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.

To the question of the construction investment impact on the business regional activity

The scale and effectiveness of investment activity is mainly associated with the creation of an attractive investment climate in the region, which reflects a combination of factors that allow the investors to safely invest in order to provide the materials, resources and get guaranteed benefits with high material output. Construction has always been distinguished by capital and material consumption, cycle time, the use of special equipment and technologies, as well as a special management system to attract and implement investments. But even with the correct calculations, investments may not bring the expected results due to lack of business and entrepreneurial resources, including those at the regional level. But on the other hand, investment processes in general, and in construction in particular, form the business activity of the region and business entities. The purpose of the study is to clarify the methodology for assessing the investments impact (general and in construction) on the business activity level in the region. The tasks of identifying the level of investments’ influence on the parameters of business activity in the region and conducting testing of the proposed developments on the Crimean region example were solved. As a result, a definition of business activity in the region was developed with the allocation of the regional socio-economic system parameters’ blocks with a justification of the investment activity characteristics, including in construction. An approach to assessing the business activity of the region is proposed, within the framework of which the correlation dependence of the investments influence on the regional business activity level is calculated using the example of the Crimean regional complex. The identified parameters of the investments’ impact flows both in construction, material production, and in innovation, can serve as the basis for developing a set of measures to stimulate the investors regarding the required indicators of the socio-economic development of the territory.
