The Greater Caucasus is a part of seismically active Alpine–Himalayan orogenic belt and has been a center of significant volcanic activity during the Quaternary period. That led to the formation of the number of hydrothermal habitats, including subterranean thermal aquifers and surface hot springs. However, there are only a limited number of scientific works reporting on the microbial communities of these habitats. Moreover, all these reports concern only studies of specific microbial taxa, carried out using classical cultivation approaches. In this work, we present first culture-independent study of hydrotherms in the Republic of North Ossetia-Alania, located in the southern part of the North Caucasus. Using 16S metabarcoding, we analyzed the composition of the microbial communities of two subterranean thermal aquifers and terrestrial hot springs of the Karmadon valley. Analysis of correlations between the chemical composition of water and the representation of key taxa allowed us to identify the key factors determining the formation of microbial communities. In addition, we were able to identify a significant number of highly abundant deep phylogenetic lineages. Our study represents a first glance on the thermophilic microbial communities of the North Caucasus and may serve as a basis for further microbiological studies of the extreme habitats of this region.

The article examines the problems of open and latent ethnonational tension in Russian society, which in the conditions of aggravation of the social situation, may lead to the use of spontaneous methods of solving ethnonational conflicts, including those of a violent nature. A survey of 20 experts, who are qualified specialists in the sphere of ethno-extremism counteraction and ethno-national conflict localization, conducted by the author of the article, has shown that the majority of them have assessed both the current and forecasted situation in the sphere of ethnonational relations as “tense” for the next five to seven years. In their opinion, “ethnonational tension” is conditioned by a number of long-term factors that will influence the content and dynamics of ethnonational conflict in the Russian Federation: the desire of the USA for global dominance and the confrontational policy of NATO member states towards Russia; the antiRussian policy of the Ukrainian leadership, which is attempting to accuse Russia of “unleashing and waging a hybrid war against Ukraine” and actively pushing Western countries to strengthen confrontation with the Russian Federation; attempts by some states to bring territorial claims against Russia; intensification of the fight against embezzlement of budgetary funds, systemic corruption and ethno-extremist manifestations in the North Caucasus region; the ethnopolitical situation in the Republic of Crimea, characterized by manifestations of Ukrainian nationalism and militant Islamism. According to expert estimates, the highest degree of ethnonational tension is currently maintained in the Republic of Dagestan, the Republic of Ingushetia, the Kabardino-Balkarian Republic, the Karachayevo-Circassian Republic, the Republic of Crimea, the Republic of Bashkortostan and the Republic of Tatarstan. The results of research in the article testify to the necessity of constant study of the problem of ethnonational conflicts, research into the factors influencing the maintenance and dynamics of conflict potential, definition of Russian regions with an increased level of tension, development of recommendations to authorities on prevention and localization of ethnonational conflicts.

Birch forests from Betula litwinowii and Betula raddeana of the Northern macroslope of the Greater Caucasus with participation of Rhododendron caucasicum in the undergrowth are discussed in the article. The studies were carried out in 2017–2020 at the territory of Karachay-Cherkessia (Teberda State Natural Biosphere Reserve), Kabardino-Balkaria (Kabardino-Balkarian State High Mountain Reserve) and the Republic of Dagestan (Lak and Gunib districts, near the villages Burshi and Batsada). The characteristics of the growing conditions, analysis of the species and coenotic composition of communities are given. Birch forests with Rh. caucasicum are usually confined to the steep slopes of the northern exposure at the upper border of the forest belt, at an altitude of 1500–2800 m above sea level. The described communities can be divided into two groups depending on abundance and, consequently, influence Rh. caucasicum as an edificator. In the described communities there is a clear inverse correlation between the abundance of Rh. caucasicum with the projective cover of the grass-dwarf shrub layer. At the same time, the number of species in the grass-dwarf shrub layer doesn’t change significantly. The species composition of birch forests with the participation of Rh. caucasicum identified by us comprises 246 species of vascular plants. The herb-dwarf shrub layer is characterized by a relatively low species richness (on average, 26 species per sample plot). In these communities there are both characteristic forest species and representatives of subal-pine and, less often, alpine coenoses. Further study of communities of birch forests, which play sig-nificant water protection role, slope-holding and avalanche-barrier functions, is important for determining their current state, possible directions of changes, and assessing the need for protective measures in different regions.

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.

The purpose of this article is to study the public opinion of residents of the North Caucasus region (on the example of the Republic of Dagestan) on the state of social and cultural adaptation and integration of foreign citizens. The relevance of the study is due to the fact that the growth of quantitative indicators of migration begins to significantly affect the ethno-social and ethno-political processes in the region and makes certain adjustments in the socio-political sphere of the republic. The main method of research is the quantitative method, i.e. a mass standardized questionnaire. The questionnaire survey was conducted taking into account the general socio-demographic characteristics of the population of the Republic of Dagestan. The content of the questionnaire is aimed at analyzing aspects of the ethnic identity of the Dagestani peoples, determining the ethno-cultural components of its reproduction, analyzing the attitude of the population of the Republic of Dagestan to the social and cultural adaptation and integration of migrants, and identifying the most effective ways to achieve this goal.

Abstract. The authors present the results of the use of herbicides on winter wheat crops in the steppe zone of North Ossetia-Alania. The purpose of the work is to study the effectiveness of the use of herbicides in winter wheat crops. The object of research is two varieties of winter wheat – Trio and Utrish, which differ in maturity, susceptibility to leaf-stem pathogens. The novelty lies in the fact that for the first time in the steppe zone of the Mozdok region, in the research and production department of the North Caucasus Research Institute of Mining and Piedmont Agriculture of the All-Russian Scientific Center of the Russian Academy of Sciences, the effectiveness of the use of herbicides in winter wheat crops was studied, an economic assessment of the studied agricultural techniques was given. Methods. The counts and observations were carried out according to generally accepted methods described in the “Educational-methodical guide for conducting research in agronomy”. Results. As a result of the use of herbicides and their tank mixture, it contributed to a significant reduction in the number of weeds (the percentage of death in the bumping phase varied between 55.9–81.1 % compared to the control). The removal of mineral nutrition elements by weeds was: nitrogen – 72.6 kg/ha, phosphorus – 14.4 kg/ha, potassium-52.4 kg/ha. Herbicides had a positive effect on photosynthetic activity. The leaf area during its maximum development (earing phase) according to the studied variants increased by 12.7–16.4 %, and the photosynthetic potential – by 13.7–17.8 %. The PPF for the studied options (the average value for the growing season) increased by 0.34–0.51 g/m2 per day. The studied drugs contributed to a significant increase in productivity. The largest increase was obtained according to the option: Grench (5 g/ha) + Luvaram (800 ml / ha) – 2.39–2.60 t/ha. The profitability level in the control (without herbicides) was at the level of 25.7 % (grade Trio), and according to the studied options ranged from 148.7 % (Luvarum 1600 ml / ha) to 169.2 % (Grench 5 g/ha + Luvaram 800 ml/ha).

Background. Paratypic variability of the development rates of barley accessions from the Republic of Dagestan was analyzed for five years in the Northwe st of Russia (Pushkin, St. Petersburg) and in the North Caucasus (Derbent, Dagestan). Responses to vernalization, photoperiodism and earliness per se were tested in contrasting environments to assess their effect on barley development. Such studies make it possible to identify valuable adaptable plant forms in the barley germplasm collection for further use in breeding practice.Materials and methods. In Dagestan, the duration of the period from shooting to heading was measured for 12 samples of barley accessions in winter and spring sowing trials. Twenty samples sown in spring in both regions were compared. An empirical indicator of plant development rate was used for barley: the criterion “the number of days by which the period from shooting to heading of an accession exceeds the minimum across a sample” (DPSH).Results and conclusions. Early barley accessions with a low norm of responsiveness were identified: k-3772, k-15013, k-15034, k-15036, k-15186, k-15192, k-21803 and k-23785 – they combined weak sensitivity to a short photoperiod and vernalizing temperatures, so they are promising for breeding in regions where the length of the growing season is a limiting factor. The effect of the responses of barley accessions from Dagestan to vernalization and a short photoperiod on the duration of the period from shooting to heading was on average 8 (5.1–10.6) days and on their earliness per se 6 (4.8–8.2) days. Paratypic variability reflects the range of variation for these indicators. In Dagestan, vernalization temperatures and insensitivity to a short day are the main factors determining the earliness of local barleys in their native environment.

According to the previously developed typology of Russian regions by the criteria of population quality, the regions were divided into ten groups. A detailed analysis of each group allows determining possible ways to improve the quality of the population in the Russian regions. This article begins to present the cycle of such studies with the analysis of three smallest groups: the first group includes Moscow and St. Petersburg, the second — the Republic of Dagestan, the Republic of Ingushetia, the Chechen Republic, the third — Nenets, Khanty-Mansi, Yamalo-Nenets autonomous okrugs and the Republic of Sakha (Yakutia). The first group of regions is the most prosperous in terms of quality characteristics of the population, here the main problem is the low natural growth of the population. The specificity of the North Caucasus republics in this aspect lies in high indicators of population quality with low material living standards that contradicts the previously statistically confirmed hypothesis of strong impact of quality of life on population quality. The conclusion has been made about high importance of national culture and traditions in these regions. At the same time, comparison of these republics among themselves has shown that traditions in some of them are weakening, and more attention should be paid to economic factors — monetary income, poverty and unemployment rates. These problems in the North Caucasus regions are in line with the theory of multilevel economy, and their solution requires restructuring of the economy on the basis of its technological and technical re-equipment. In the third group, on the contrary, high monetary income is accompanied by poor qualitative characteristics of the population, especially by rates of alcoholism and drug addiction. These phenomena are correlated with the level of unemployment, the growth of which is caused not only by the global crisis processes in the development of the oil and gas sector, but also by the depletion of highly profitable deposits in the Northern regions of the country, the need to develop hard-to-reach and hardly removable sources of oil and gas. The solution may be to change the structure of the economy of these regions in the direction of development of the natural raw materials processing sector.

Aim. The paper analyses the Islamic revival in Russia in the late 20th century and early 21st. This was reflected in the registration of religious communities, the publication of periodicals on Muslim literature, and, in my opinion, most importantly - the construction of mosques and madrassas. It highlights the roles of mosques and madrassas built in the North Caucasus, which later became the theological centers for the spread of Islam and educated youngsters according to their propaganda. Methods. The study mainly uses an analysis method based on the study of historicism, documents and empirical material. The basis of the source are books, scientific articles, research works conducted by Russian and foreign experts. Results. The post-Soviet wars (1994-1996 and 1999-2000) in Chechnya contributed to the politicisation and realisation of Islam in this region. In 1996-1999 there were 26 Sharia courts, numerous Islamic parties, charitable foundations and organisations in the republic and, most importantly, structures of Wahhabi organisations (Akaev, n.d.). The process of politicisation gradually turned into organisational formations in Russia in the late 1980s and early 1990s. Conclusion. The constructive transformation by reinforcing the modernist potentials of Islam has contributed to the real renewal of Russian Muslim societies, which led to the radicalisation of the whole region. The described events have shown that for the last 20 years, the revival of religious Islam was a revival of political organisations and activities, where religion is connected to politics and criminal activities. A small North Caucasian republic immediately turned up at the center of Russia's recent history. Key Words: Islam, politics, revival, radicalization, Russia, North Caucasus
