AbstractArchaeogenetic studies have described the formation of Eurasian ‘steppe ancestry’ as a mixture of Eastern and Caucasus hunter-gatherers. However, it remains unclear when and where this ancestry arose and whether it was related to a horizon of cultural innovations in the 4thmillennium BCE that subsequently facilitated the advance of pastoral societies likely linked to the dispersal of Indo-European languages. To address this, we generated genome-wide SNP data from 45 prehistoric individuals along a 3000-year temporal transect in the North Caucasus. We observe a genetic separation between the groups of the Caucasus and those of the adjacent steppe. The Caucasus groups are genetically similar to contemporaneous populations south of it, suggesting that – unlike today – the Caucasus acted as a bridge rather than an insurmountable barrier to human movement. The steppe groups from Yamnaya and subsequent pastoralist cultures show evidence for previously undetected farmer-related ancestry from different contact zones, while Steppe Maykop individuals harbour additional Upper Palaeolithic Siberian and Native American related ancestry.

Indo-European languages have been spoken in the Caucasus over millenia, alongside languages of the three indigenous families of the region. This chapter provides a general overview of four languages whose core area is situated in the Caucasus (both the North Caucasus and Transcaucasia): Eastern Armenian (which together with Western Armenian forms a separate branch of Indo-European) and three Iranian languages: Ossetic, spoken in North Ossetia, part of Russia, and South Ossetia beyond the mountain range; Judeo-Tat, spoken by Mountain Jews in Dagestan and Azerbaijan; and Talyshi, spoken by the Talysh people mainly in the south of Azerbaijan, but also in neighboring regions of Iran. The chapter captures the current understanding of the core areas of phonology and grammar of these languages and provides information on features that could possibly have been induced by contact with the neighboring Caucasian languages.

In the 2000s, Al-Qaeda, represented by the Caucasus Emirate, took over the first Chechen resistance, as well as local Islamist armed groups in Dagestan and other republics of the North Caucasus. However, a decade later, the Islamic State won the competition with Al-Qaeda, by including the involvement of women in its project. Hundreds of Russian-speaking Muslim women followed men to live by the rules of Islam. Some joined their husbands or children. Others travelled to the Islamic State in pursuit of love and romance with future husbands they had met on the internet. Based on exclusive interviews done with women detained in the Roj detention camp in the Kurdish territories in northeastern Syria near the Iraqi border, this article analyzes some of the trajectories that has pushed young North Caucasian women to the Syrian war theater in the name of love.

AbstractDetailed information on species delineation and population genetic structure is a prerequisite for designing effective restoration and conservation strategies for imperiled organisms. Phylogenomic and population genomic analyses based on genome-wide double digest restriction-site associated DNA sequencing (ddRAD-Seq) data has identified three allopatric lineages in the North American freshwater mussel genus Cyprogenia. Cyprogenia stegaria is restricted to the Eastern Highlands and displays little genetic structuring within this region. However, two allopatric lineages of C. aberti in the Ozark and Ouachita highlands exhibit substantial levels (mean uncorrected FST = 0.368) of genetic differentiation and each warrants recognition as a distinct evolutionary lineage. Lineages of Cyprogenia in the Ouachita and Ozark highlands are further subdivided reflecting structuring at the level of river systems. Species tree inference and species delimitation in a Bayesian framework using single nucleotide polymorphisms (SNP) data supported results from phylogenetic analyses, and supports three species of Cyprogenia over the currently recognized two species. A comparison of SNPs generated from both destructively and non-destructively collected samples revealed no significant difference in the SNP error rate, quality and amount of ddRAD sequence reads, indicating that nondestructive or trace samples can be effectively utilized to generate SNP data for organisms for which destructive sampling is not permitted.

Objective: Chirkeyskaya HPP is by far the most powerful hydroelectric power plant in the North Caucasus with the highest arched dam in Russia and the second highest dam in the country after the Sayano-Shushenskaya HPP. This explains why it is called the pearl of the Caucasus. Methods: For the operation and maintenance of this unique structure, a large-scale complex of underground structures for various purposes was built, the technical condition of which must be constantly monitored. To carry out work on the survey of underground structures, the management of the design and survey institute of JSC “Lengidroproekt” decided to attract specialists from the Department of Tunnels and Subways and the Test Center “Strength” of Emperor Alexander I Petersburg State Transport University. The work was successfully carried out at the end of 2015. Results: The safety of underground structures was objectively assessed. Recommendations for the repair and further comprehensive reconstruction of the Chirkeyskaya HPP have been developed. Practical importance: Carry out work on the survey of underground structures of Chirkeyskaya HPP is allowes elaborate of complex measures on safety from Chirkeyskaya HPP.

В статье анализируются причины строительства Владикавказской железной дороги и механизм сооружения этой важной железнодорожной артерии. Актуальность темы анализа истории развития железнодорожной сети Северо-Кавказского региона определяется необходимостью подробного изучения проблем ее социально-экономического развития. Строительство Ростово-Владикавказской железной дороги также является примером государственно-частного сотрудничества, которое хорошо себя оправдало. Дорога была построена полностью за счет средств акционеров, среди которых были как крупные промышленники, так и простые обыватели. Находясь в частной собственности, Владикавказская железная дорога хорошо функционировала и развивалась. При этом государство получило важную транспортную артерию, имевшую большое экономическое и военно-стратегическое значение. Немаловажным было и то, что за счет Владикавказской железной дороги был построен ряд социальных объектов – больницы, учебные заведения. В статье также показана заинтересованность общественности Владикавказа и региона в целом в строительстве железной дороги. Различные варианты прокладки пути, строительства станций широко обсуждались как специалистами, так и простыми горожанами. В итоге был выбран наиболее оптимальный путь и месторасположения станции Владикавказ. В свое время, благодаря открытию Владикавказской железной дороги, был дан заметный импульс дальнейшему развитию торговли и промышленности на Северном Кавказе. Последующее расширение транспортных артерий уже в наши дни может существенно оживить экономику Кавказа и России в целом, а также внести свой вклад в деле развития туризма в регионе. В связи с этим и необходимо анализировать историю строительства Владикавказской железной дороги и перенимать лучший опыт прошлого. The article analyzes the reasons for constructing Vladikavkaz railway and the mechanism of constructing this important railway artery. The topic relevance of studying the history of the railway network in the North Caucasus is determined by the necessity for further problem research of its socio-economic development. In its time Vladikavkaz railway had a huge impact on the development of trade and industry in the North Caucasus. The construction of the Rostov-Vladikavkaz railway is also an example of public-private cooperation, which has paid off well. The road was built entirely at the expense of shareholders, among whom were both large industrialists and ordinary people. Being privately owned, the Vladikavkaz railway functioned and developedwell. At the same time, the state acquired an important transport artery of great economic and military-strategic importance. It was also important that a number of social facilities were built at the expense of the Vladikavkaz railway - hospitals, educational institutions. The article also shows the interest of the public in Vladikavkaz and the region as a whole in the construction of the railway. Various options for laying the track, building stations were widely discussed by both specialists and ordinary citizens. As a result, the most optimal route and location of the Vladikavkaz station were chosen. Further expansion of transport arteries today can significantly revive the economy of the Caucasus and Russia as a whole, as well as contribute to the development of tourism in the region. In this regard, it is necessary to analyze the history of constructing Vladikavkaz railway and adopt the best experience of the past.

AbstractThe genus Castanea in North America contains multiple tree and shrub taxa of conservation concern. The two species within the group, American chestnut (Castanea dentata) and chinquapin (C. pumila sensu lato), display remarkable morphological diversity across their distributions in the eastern United States and southern Ontario. Previous investigators have hypothesized that hybridization between C. dentata and C. pumila has played an important role in generating morphological variation in wild populations. A putative hybrid taxon, Castanea alabamensis, was identified in northern Alabama in the early 20th century; however, the question of its hybridity has been unresolved. We tested the hypothesized hybrid origin of C. alabamensis using genome-wide sequence-based genotyping of C. alabamensis, all currently recognized North American Castanea taxa, and two Asian Castanea species at >100,000 single-nucleotide polymorphism (SNP) loci. With these data, we generated a high-resolution phylogeny, tested for admixture among taxa, and analyzed population genetic structure of the study taxa. Bayesian clustering and principal components analysis provided no evidence of admixture between C. dentata and C. pumila in C. alabamensis genomes. Phylogenetic analysis of genome-wide SNP data indicated that C. alabamensis forms a distinct group within C. pumila sensu lato. Our results are consistent with the model of a nonhybrid origin for C. alabamensis. Our finding of C. alabamensis as a genetically and morphologically distinct group within the North American chinquapin complex provides further impetus for the study and conservation of the North American Castanea species.

В статье на основе исследований российских ученых, архивных документов, воспоминаний рассматривается слабо изученная в отечественной историографии проблема участия представителей этнических меньшинств в битвах за Кавказ и Крым в ходе Великой Отечественной войны. В качестве примера автором избраны этнические общности курдов и корейцев. Использованы историко-генетический, историко-биографический и системно-исторический методы. Изучены меры советского командования по формированию национальных воинских подразделений; реконструированы биографии героев войны – корейцев и курдов, участвовавших в освобождении Юга России и получивших боевые награды; прослежена их послевоенная судьба; рассмотрены репрессивные действия советского правительства по отношению к военнослужащим некоторых национальностей. Автор заключает, что представители разных народов СССР, столкнувшись с врагом, проявили стремление к единству и добровольное желание выступить на защиту государства, которое они избрали своей Родиной. The aim of the article is to reconstruct the biographies of participants in the Great Patriotic War (1941–1945), who belonged to ethnic minorities and fought for the liberation of the Caucasus and Crimea from Nazi invaders. As an example, the author selected ethnic communities of Kurds and Koreans. The study was conducted on the basis of research by Russian scholars, archival documents, and memoirs of direct participants in the events. The historical-genetic, historical-biographical and system-historical methods were used. The measures of the Soviet command for the formation of national military units were studied, the biographies of war heroes, Koreans and Kurds who participated in the liberation of the South of Russia and received military awards (including the title Hero of the Soviet Union) were reconstructed. The author describes in detail the military clashes during which these fighters showed military prowess, presents their photographs, and traces their further military path, post-war fate and forms of their memory perpetuation. Quotations from the war veterans’ front-line letters and their relatives’ memoirs are given. The repressive actions of the Soviet government towards the military personnel of certain nationalities, who after the demobilization received the status of “special settlers” and lost their military tickets and award sheets, are also considered. The author emphasizes that the fight against the enemy was a test of strength for the unity of the peoples living in the Caucasus and Crimea. Examples of civic solidarity in the fight against the enemy shown by ethnic minorities in the early days of the war (mass enrollment in volunteers, holding civil rallies) are given. It is noted that representatives of local ethnic communities became the basis of 12 military units that were at the forefront of the defenders of the Caucasus. The paradoxical nature of the situation in which USSR citizens were repressed for various (often far-fetched) reasons is stated; however, during the war they still heroically fought against Nazism with arms in their hands. The author connects the repressions against members of the ethnic minorities with the ethnosocial policy pursued by the Soviet state, as well as the spread of desertion and draft evasion in the North Caucasus and Crimea. It is concluded that representatives of ethnic minorities living in the USSR, faced with the enemy, showed a desire for unity and a voluntary desire to defend the state, which they chose as their homeland.

The North Caucasus is a most significant but a least understood problem in contemporary U.S.-Russia relations. The United States as one of the prime pace-setters in the region shaped its own attitude towards Russia’s most volatile region. Over more than twenty years, Washington experienced at least three major stages in its “Caucasus strategy”, and each stage had its impact on the North Caucasus. Since the beginning, the two states stuck to conflicting narratives of developments in the region. With time, some of the assessments were re-evaluated, but some continue to impede cooperation on key security issues. The present article explores these phenomena and examines what implications major events like the 9/11 attacks, the Caucasus Emirate enlistment among top terrorist organisations, the Boston marathon bombings, etc. had for the U.S.-Russia joint efforts in fighting terrorism. It also assesses areas of potential disagreement in the North Caucasus between the two countries.

The problem of the need for construction of railways in the North Caucasus as a strategically and economically important enterprise for maintaining and developing the viability of the region is considered. Preconditions and opinions on the appropriateness of railway connection are given. To achieve this goal in the region, it was decided to establish a new joint-stock company of the Rostov-Vladikavkaz railway. The dynamics is investigated from planning, choosing the final direction from those proposed by the engineers who carried out surveys on the ground, to the actual opening of permanent traffic on the first (main) line of the Rostov-on-Don - Vladikavkaz Society - the first highway that connected the Caucasus with the central part of the state in 1875 ... A brief description of this path is given. The geography of the line was investigated. Some stages of further development are given, the results and opinions obtained during the operation of the road are summed up. The issue of location and development of the Rostov railway junction is considered. Already in the first years of operation, the enormous potential of railway transport in the North Caucasus was obvious, not only strategically, but also as an economically important enterprise that opened up new opportunities for the development of the region, which in turn made the railway the main industrial giant.
