Кленовники Северного Кавказа – особый тип лесных формаций. Особенность проявляется не только в структуре фитоценозов, но и в способах самовозобновления. Объект исследования – чистые и смешанные кленовники в нескольких урочищах РСО-Алания. Объекты расположены в различных условиях горного рельефа и на разной высоте над уровнем моря, от 1100 до 1900 м. Целью исследования является установление особенностей семенного возобновления кленовников, произрастающих в верхнем поясе распространения лесов на Северном Кавказе. Для достижения поставленной цели устанавливали время цветения и созревания семян по вертикальным поясам распространения кленовников. Обилие цветения и средний балл плодоношения устанавливали по В.Г. Капперу. Биометрические характеристики семян определяли по урочищам в трех повторностях. Учет подроста проводили на круговых учетных площадках по 10 м2, в соответствии с методикой А.В. Грязькина. Установлено, что цветение клена Траутфеттера начинается 10–14 мая и заканчивается в третьей декаде мая. Семена начинают созревать к концу августа – к началу сентября. Сроки опадения семян растянуты. Часть семян попадает на почву до начала листопада, поэтому они оказываются погребенными под опадом. Такие семена быстро теряют всхожесть, выпревают. Другая часть опадает вместе с листьями. Третья категория семян (самые легкие) держатся на деревьях до декабря и даже до весны. Естественное возобновление клена семенами под пологом материнского древостоя сильно затруднено из-за мощного травяного покрова. В древостое с сомкнутым пологом доля цветущих и плодоносящих деревьев составляет 2–3%, а средний балл плодоношения составляет 1,3. Освещенность на поверхности почвы не превышает 100 люкс, т. е. составляет 0,2–0,3% от освещенности на открытом месте; на высоте 1,3 м (над травостоем) освещенность несколько выше – от 1,2 до 1,6 тыс. люкс. Под пологом древостоя преобладает подрост вегетативного происхождения. У верхней границы кленового леса подрост семенного происхождения встречается в окнах, прогалинах и на открытых местах в количестве 430–630 экз./га. По высоте преобладает крупный подрост 50–60%, доля мелкого – 10–20%. The maple stands of the North Caucasus – a special type of forest formations. The peculiarity is manifested not only in the structure of phytocoenoses, but also in the ways of self-renewing. Object of research – pure and mixed maple stands in some areas of North Ossetia-Alania. The properties are located in various mountainous terrain and at different heights above sea level from 1100 to 1900 m. The aim of the study is to establish the characteristics of the seed the resumption of the maple stands growing in the upper belt of forests spread in the Northern Caucasus. To achieve this goal setting time of flowering and ripening of seeds on vertical zones distribution dominated. The abundance of flowering and the average score of fruiting was established by V.G. Capper. Biometric characteristics of the seeds was determined by the tracts in three replicates. Accounting for the undergrowth was carried out on a circular experimental plots at 10 m2, in accordance with the method of A.V. Grashkin. It is established that the flowering maple Trautvetter begins may 10–14 and ends in the third week of may. Seeds begin to ripen by late August – early September. The timing of subsidence of the stretched seed. Some of the seeds falls to the ground before the leaves, so they are trapped under the litter. These seeds quickly lose their germination, vypivaet. The other part falls along with the leaves. The third category of seeds (the light) stay on the trees until December and even till spring. Natural regeneration of maple seeds under the canopy of parent stand is very difficult due to the strong grass cover. In forest stands with dense canopy, proportion of flowering and fruit-bearing trees is 2–3%, and the average score of fruiting is 1.3. The illumination on the surface of the soil does not exceed 100 Lux, i. e. 0.2–0.3% of the light in the open, at a height of 1.3 m (on grass) the lighting is slightly higher, from 1.2 to 1.6 thousand Suite. Under the canopy of the forest the undergrowth is dominated by vegetative origin. At the upper boundary of the maple forest, saplings of seed origin occurs in Windows, clearings and open places in the number 430–630 ind./ha. In height dominated by large undergrowth of 50–60%, the share of small – 10–20%.

The article analyzes the educational policy of Russia regarding the Muslims of the North Caucasus, substantiates the formation of the educational potential of the Muslim mountaineers in the historical aspect associated with the evolution of the educational paradigm of the state in the field of their education, the result of which was the adaptation of the regional structure of education to the all-Russian system. It is concluded that the imperial government, adapting to the situation of capitalism and carrying out modernization in the region, began to pay more attention to the issues of enlightening "infidels". But due to the inconsistent policy of officials, the coverage of Muslims by training was insufficient and required further reform of the national educational system.

The article proposes a methodological approach to potential damage from natural hazards forecasting in case of large-scale investment projects realization in ski tourism planning, as well as to assessing changes in the vulnerability of the territory in which these projects will be implemented. The method was verified on the data of the “Northern Caucasus Resorts” tourist cluster. The study purpose is the creation and verification of a methodology for socio-economic damage predicting in limit values and vulnerability changing in the regions of the “North Caucasus Resorts” tourist cluster objects localization for the long term. Research methods – statistical (a structural approach based on the identification of common structural patterns of several sets). The lack of statistical information on significant parameters for forecasting determine necessitates of using the various logically non-contradictory revaluations based on the identified structural similarities for the calculation of their values within the planning horizon. The study results and main conclusions – in case of the “North Caucasus Resorts” tourist cluster creation the number of people potentially located in avalanche and mudflow danger areas will significantly increase in all of its facilities localization municipalities, which indicate an increase in the individual risk of death level for this territory. The present population in the ski season in some of the most remote and underdeveloped areas can increase up to 30 times. The increment in the value of the fixed assets for the municipalities under consideration will be from two to 90 times, potential damages in limit values will reach tens of billions rubles.

Abstract Goat breeding is a traditional livestock industry for many regions of Russia. Due to unpretentiousness and high adaptive qualities, the Karachai, Dagestan wool and Dagestan down breeds are widespread in the North Caucasus. Moreover, their uniqueness is determined by sharing a common habitat with their wild relatives, West Caucasian and Dagestani turs, thus forming hybrid zones. The aim of the research was to study allele pool and interbreed differentiation of domestic goat breeds and wild relatives by microsatellites. Research was performed based on 16 loci on the ABI 3130xl analyzer. Population genetic characteristics were calculated in GenAlEx 6.5, and the phylogenetic tree was constructed in Populations 1.2.30 and SplitsTree 4.14.5. The sample collection included goat breeds (n = 226): Karachai (KRCH), Dagestan down (DAGD), Dagestan wool (DAGW) (North Caucasus), Soviet wool (SOVW) (Siberia), Orenburg (OREN) (South Ural), and wild goats (n = 72). Wild goats comprised mountain goats: Siberian goats (Capra sibirica) from the Altai, Tajikistan, Kyrgyzstan and the Himalayas; bezoar goats (Capra aegagrus) from Turkey and Pakistan; and tur (Capra caucasica) from the West Caucasus (Kuban), Central Caucasus, and East Caucasus (Dagestan). The Karachai breed was characterized by the highest level of genetic diversity: the average number of alleles per locus (NA) and allelic richness (AR) were 9,154 and 7,713, respectively, while these indices varied from 6,538 to 7,538 and from 6,425 to 7,538 (Table 1) in other breeds, respectively. The values of genetic distances showed differentiation of Karachai, Dagestan down and Dagestan wool breeds from Orenburg and Soviet wool breeds (Table 2). The formation of three clusters was established. The first one included subspecies of the Caucasian tur, the second one comprised Siberian goats, and the third contained domestic goats. Bezoar goats were in the root of the third cluster that confirmed their participation as an ancestral form of domestic goats.

The article is dedicated to the analysis of archeological excavation as a result of researches discovered in the Mingachevir conducted in the middle of the 20th century of the different type of underground burials of the ancient period. These burials are covered the significant historical period from the second half of the 1st millenium and the first century AD and are the important source of the scientific information on many issues of material and spiritual culture of the population of Caucasus Albania. Underground burials of the ancient period in the Mingachevir zone by the method of placing the deceased in them are divided into three types: 1) burials with a backbone stretched out on the back; 2) burials with a weakly crouched skeleton on the left or right side; 3) burials with a heavily crouched skeleton on the left or right side. The article gives a detailed analysis of all these three types of burials. The author of the article, along with a number of other researchers come to the conclusion that the first type of underground burial is considered to be innovation for the whole of the South Caucasus and its emergence is associated with the penetration of mobile tribes from the North Caucasus in particular the Scythian. Part of these Scythians finally settled in the Mingachevir zone and subsequently merged with the local population, which eventually leads to the appearance of a second type of underground burial in the form of underground graves with poorly crouched skeleton. The third type of underground burial of Mingachevir (Samunis) of the ancient period, namely burials with a heavily crouched skeleton belong to local autochthonous tribes, consolidation of which became the basis for the formation of the state of Caucasian Albania in the 4th – 3rd centuries BC. This type of underground burial has deep local roots and is based on centuries-old local funerary rituals.

The article presents an assessment of technogenic impact on the development of hazardous geological processes in the mountainous regions of the Northern Caucasus in the current century. Technogenic impact is determined by the stability of rock formations that make up the Krasnodar Territory, Kabardino-Balkaria, and North Ossetia relative to the impacts of other forces. It is also noted that the activity of hazardous geological processes is largely determined by the interaction of climatic conditions, which determine their speed, and technogenesis. Examples of problematic territories of the North Caucasus are given. To assess climatic changes and major catastrophes, a typology of atmospheric circulation in the Northern Hemisphere was developed under the leadership of B.L. Dzerdzeevsky. Typification materials from the period between 1899 and 2018 are posted in the public domain, at www.atmospheric-circulation.ru. The largest catastrophes, in which landslides and mudflows became more active, and the interaction of natural and man-made factors in these disasters are considered.Hazardous geological processes can disrupt the sustainable development of individual regions with their negative impact on the environment. The assessment of their danger is therefore of special current relevance. The article considers the possibility of predicting catastrophes associated with these processes. Long-term forecasts of landslides, mudflows and other processes continue to be important. The methodology of such forecasting was previously developed in sufficient detail. The greatest importance is assigned to operational forecasts that will make it possible to warn of possible danger hours or even days ahead.

The published documents were found in the archives of the Republic of North Ossetia-Alania. These are the materials of the meetings of the Soviet and party authorities of the Mountain Republic, which were devoted to the discussion of the problem of Kabarda's secession from the polyethnic mountain autonomy. The Kabardian problem was discussed several times by the leadership of the Mountain Republic in June 1921 before and after the congress of the peoples of Kabarda that took place this month. The minutes of the meetings have not yet been published in the published thematic collections of documents dedicated to the history of the nation-building of the peoples of the North Caucasus. The documents contribute to the understanding of the position of the statesmen of the Mountain Republic on the formation of new autonomous units and the identification of the concrete historical content of these processes. The protocols make it possible to reconstruct the process of not only the disintegration of the collective mountain statehood, but also make it possible to clarify important points in the history of its creation. Party and Soviet leaders often returned to the problems of the initial stage of the formation of the Mountain Republic. Further study of the problems of the formation of a system of national autonomies in the North Caucasus in recent times will largely depend, including on the introduction of new documents into scientific circulation and their interpretation by a wide range of researchers. In this regard, the published documents and materials are of great scientific interest.

A nuanced reading of the current situation in the North Caucasus reveals two main trends that articulate in confrontation with Russian nationalism. First, in the eastern part of the region, particularly in Dagestan, Chechnya, and Ingushetia, a shift from nationalism to Islam has taken place, and the ties between religion and political machine are strong and visible. Second, and by contrast, in the western part of the region, including Adygea, Kabardino-Balkaria, Karachayevo-Cherkessia, and North Ossetia, nationalism has increased, and the political elites seldom practice religion publicly.
