Full textAbstract:
The Yenisei is one of the largest rivers on our planet. Flowing from south to north, it crosses all the natural zones of Siberia. The Yenisei basin covers the mountains and intermountain hollows of the Altai-Sayan mountainous country, the plateaus of Central and the lowlands of Western Siberia. The ichthyofauna of the flat part of the Yenisei basin is relatively well studied, while the data on the fish of the water bodies of the Western Sayan which are part of the Yenisei basin is limited in the available literature, and includes information only about the fish of some lakes. In this work, we studied of the ichthyofauna and the fish community of different types of water bodies in a specially protected natural area in the central part of the Western Sayan, in the Ergaki Natural Park — the Nizhnyaya Buiba and Bolshaya Oya rivers, and information about the ichthyofauna of Lake Oyskoye was clarified. In the studied water bodies, three species of fish (typical for rivers and lakes of the mountains of southern Siberia) were identified: Arctic grayling Thymallus arcticus (Pallas, 1776), Siberian loach Barbatula toni (Dybowski, 1869) and Eurasian minnow Phoxinus phoxinus (Linnaeus, 1758). Previously there was no information about the presence of Siberian loach in water bodies on the territory of the Ergaki Natural Park in the available scientific literature. The abundance and biomass of fish species varies significantly in different water bodies. Arctic grayling is common or dominant in rivers, Eurasian minnow is super dominant in the Nizhnyaya Buiba river and in the Oyskoe lake. In the Bolshaya Oya river, the superdominant species is the Siberian loach. Eurasian minnow in the Oyskoe lake is large of size.

Full textAbstract:
The fauna of the rivers of the north of Western Siberia that do not belong to the Ob’ River basin is of particular interest from the point of view of zoogeography and understanding of the processes of formation of the freshwater malacofauna. Starting in the taiga zone, these rivers flow north and cannot serve as a way of interzonal dispersal of species from lower latitudes. However, information about the fresh-water malacofauna of these river basins is poorly presented in the scientific literature, some of the published species findings are doubtful or erroneous. The gastropod mollusks of the family Valvatidae of the Taz river basin (Western Siberia) are considered. The basin is located closer to the Yenisei than to the Ob’ River basin. The study was based on original authors’ material represented by both qualitative and quantitative samples. It has been found that eight species of mollusks of the genus Valvata occurs in the water reservoirs and streams of the Taz basin, an annotated list of species is presented, and a brief zoogeographic characteristic is given. Three species (Valvata helicoidea, V. sorensis and V. korotnevi) are for the first time recorded from the basin, one of them (V. korotnevi) is for the first time recorded from the Western Siberia waterbodies.

Full textAbstract:
Based on a study of samples made by the author, 70 species of freshwater bivalves belonging to 6 genera and 2 families are recorded for the Taz River basin (north of Western Siberia). An annotated list of bivalves of the Taz basin is provided, with data on species’ range, their findings in Western Siberia and within the studied area. Some information about bionomics and abundance of bivalves are given. 45 species are for the first time registered in this basin. Most studied molluscan communities are characterized by low species richness; the distribution of species by their occurrence was extremely uneven. 22 species are characterized as rare. The highest species richness of bivalves was found in river channels, rivers and brooks; the lowest - in temporary habitats. The core of the fauna is constituted by species with broadest range (cosmopolitan, trans Holarctic, trans Palearctic) as well as by taxa with European Siberian type of distribution. From the taxonomic point of view, the bivalve fauna of the Taz basin is relatively separated from the faunas of other river basins of Western Siberia and is more similar to the fauna of the Lower Yenisean zoogeographic province (sensu Starobogatov [1986]).

Full textAbstract:
The presence of ammonites of the subfamily Collignoniceratinae has been established in the Turonian Stage of Western Siberia. These findings allowed us to recognize the Collignoniceras woollgari zone in the Middle Turonian of this region, as well as to recognize the peculiarities of ammonite dispersal in the Arctic and clarify the palaeogeography of the Turonian age. Based on the frequency of occurrence of Collignoniceras woollgari regulare in the boreholes in the north of Western Siberia, their penetration into the West Siberian basin through the Arctic from the Western Interiort Sea of North America is most likely. For the first time Collignoniceratinae were determined in the Upper Turonian of the Yangoda River (west of the Yenisei-Khatanga regional trough).

Full textAbstract:
The aim of the study is to determine the influence of transport accessibility of Western Siberia and the Yugra North on the similarity of customary law among the Russian and aboriginal population in the XIX – the early XX century. The scientific novelty of the paper lies in comparing the legal customs of the immigrant and aboriginal population of Western Siberia with an emphasis on their “magical” component and the role of the transport system of the region in consolidating these features in the XIX – the early XX century. The paper has revealed the importance of rivers and land roads in the formation of legal customs of Russian settlers, analyzed the content of Ancient Slavic “rowdiness” and its correspondence to the legislation of the Russian Empire, substantiated the similarity of the “magical” ideas of the Ob Ugrians, who professed shamanism, and remnants of paganism among the settlers from the Russian Orthodox population. The results of the study have shown that custom ensured survival in Siberia, so customary law affected the entire rural and nomadic population of Western Siberia and was expressed in a variety of local forms. Despite the similarity of legal customs among Russian Siberians and the aboriginal population, there were also differences that reflected the religious worldview and lifestyle, as well as the degree of influence of Russian legislation. The process of convergence of legal norms took place in conditions when rapid movement from one region to another was impossible and the difficult transport accessibility of the region was the key factor. Meanwhile, eventually, there was a positive effect, because a much greater cultural understanding between the indigenous and the immigrant population was formed than had been observed at the initial stage of the migration of Russians to Siberia.

Full textAbstract:
The activities of military topographers in Western Siberia to provide cartographic information on the foreign and domestic policies of the Russian Empire in Central Asia and Siberia in the 19th century are considered in the article. The role of information in the formation of the Russian Empire is emphasized. The contribution of the state to the organization of the study of the Asian regions of Russia and neighboring countries is noted. The establishment of the military topographic service in Western Siberia can be traced taking into account data on administrative transformations in the Siberian region, and on changes in the foreign policy of the Russian Empire. The participation of military topographers in determining and designating the state border with China is described in detail. The question of the role of military topographers in the scientific study of China and Mongolia is raised. The significance of the activities of military topographers for the policy of the Russian Empire on the socio-economic development of Siberia and the north-eastern part of the territory of modern Kazakhstan is revealed. The contribution of topographers to the construction of the Trans-Siberian railway, the design of river channels and new land routes is revealed. A large amount of literary sources, materials on the work of military topographers of Western Siberia, published in “Notes of the Military Topographic Department of the General Staff” is used in the article.

Full textAbstract:
In this paper, a unique pottery complex of the Eneolithic period from the settlement of Pyakupur 3, located along the upper course of the Pur River in the sub-zone of the northern taiga, has been analyzed. The aim of this research is to establish cultural traditions of the population who left the settlement behind and to determine the place of the materials within the current system of historical and cultural types identified in the north of Western Siberia. The material for the research is represented by morphological traits of the pottery and by some elements of the pot-tery technology as a manifestation of the cultural traditions of the populations who inhabited the headland of the ter-race of the Pyakupur River in the Eneolithic period. In total, 38 vessels have been included in the analysis, most of which are represented by fragments of the original walls and bottoms; only eleven containers had a collared rim. For the purpose of this work, conventional methods of archaeological research were employed: morphological, statisti-cal, and typological. Furthermore, technical and technological analysis of a part of the collection was carried out with the aid of a binocular microscope MBS-10 following the method of A.A. Bobrinsky. The pottery features the following basic traits: decorated, smaller, and thin-walled vessels. Among the shapes, a significant proportion of cymbiforms stands out, with the rest of the vessels being round-bottomed and one pot — a cup with a ridge. As the ornamenta-tion tools, crested (predominant) and smooth stamps were used, rarely profiled (wire staple), although they practi-cally are not found side by side on the same vessel. The main technique of the ornamentation was embossing. At the level of elements and motifs, presswork and horizontal rows predominate; a significant percentage in the compo-sitions is represented by geometrical patterns. The compositions are more often complex, combining several motifs. It has been found that the pottery of the settlement of Pyakupur 3, exhibiting considerable idiosyncrasy, closely re-sembles the wares of forest-tundra and tundra settlements, rather than the complexes of the northern-taiga Yasun-skaya Culture or antiquities of the middle taiga of Western Siberia, suggesting some cultural affinity of the popula-tions inhabiting these remote from each other territories. However, chronologically, Pyakupur 3 precedes the sites of Gorniy Samotnel 1, Salekhard 1, Ust-Vasyegan 1, and the later, still Eneolithic, settlement of Vary-Khadyta II. The paucity of the source base from the territories of the basins of the rivers Pur and Taz yet does not allow one to an-swer multiple questions following from this conjecture.

Full textAbstract:
The authors show the differentiation of the modern aeolian landforms spatial distribution (natural and anthropogenic origin) for the northern part of the West Siberian Plain (an area of about 800 thousand km2) based on the analytical processing of Sentinel-2 satellite images (resolution 10 m/px). A deciphering technique was developed; it includes the use of unsupervised ISODATA classification algorithms, visual editing, verification of results based on high-resolution satellite images, and standard spatial analysis procedures. In total, 404,675 aeolian relief objects with a total area of 2228,18 km2 were identified. The average area of natural forms was 0,44 ha (the largest share in the Yamal district of the Yamalo-Nenets Autonomous Okrug – 1,02 %), the average area of anthropogenic forms – 2,84 ha (the largest share in the Purovsky district of the same region – 0,19 %). It was revealed that in the territories of oil and gas production, the maximum area of both natural and anthropogenic aeolian forms corresponds to the boundaries of the Urengoy field (19,14 and 34,58 km2, respectively). It was established that in the Yamal Peninsula, the modern aeolian relief is confined mainly to marine and hydroglacial deposits, while in that of Gydan Peninsula, a connection can be traced with glacial or marine ones that have experienced direct mechanical action of cover ice. It was revealed that the mentioned relief is often formed in areas with increased drainage, facing towards the direction of the prevailing winds in the spring-autumn period (terraces and the watershed of the Pur and Nadym rivers). The results of the study can be used at monitoring the reclamation of disturbed areas and the natural dynamics of vegetation as an indicator of global climate change in the north of Western Siberia.

Full textAbstract:
Hirudinea, a small and ecologically important group of aquatic organisms, is poorly studied in northern Eurasia. In this study, we demyth the idea of the faunistic poverty of this region and present the first findings of rheophilic leeches from the Khanty-Mansi Autonomous Area, Russia. Investigation of 25 rivers (Severnaya Sosva, Ob, Konda-Irtysh, and Bolshoi Yugan river basins) resulted in finding 10 leech species with parasitic and non-parasitic life strategies. These species belong to two orders (Rhynchobdellida and Arhynchobdellida), three families (Glossiphoniidae, Piscicolidae, and Erpobdellidae) and six genera (Alboglossiphonia, Glossiphonia, Helobdella, Hemiclepsis, Piscicola, and Erpobdella). Five species, A. hyalina, G. verrucata, E. monostriata, E. vilnensis, and potentially new morphological species of piscine leeches Piscicola sp., have been discovered for the first time in Western Siberia. Data on species diversity of rheophilic leeches include the exact systematic position for all leech taxa. Each species from the list is supplemented with information about its geographical distribution.

Purpose. The article outlines three large provinces on the Asian territory of Russia which determine morphology of Neolithic ceramic ware (Amour River region and border areas of Far East and Pacific Ocean islands; Trans-Baikal region and Eastern Siberia, Western Siberia). Western Siberia is a territory where, in the Neolithic Age, such traditional shapes as round-, point- and flat-bottomed ones were spread. At the same time, inside the region, two areas – Western (trans-Ural and North-Western regions of Barabinskaya forest-steppe) and Eastern (Barabinskaya forest-steppe, high Ob area, including forest-steppes of Altai, and its foothills, and Kuznetsk basin) are outlined. If in the western part two traditions have been determined, in the eastern part, only one tradition – round-bottomed ceramic ware, has been found so far. Morphological specifics of ceramic assemblages of the Neolithic in the trans-Ural region caused a polemic in solving the issue of their cultural and chronological attribution. The stratified sites of Andreevskaya Lake System were the base of the main line of reasoning. The article presents a critical analysis bringing into question the use of stratified sites of Andreevskaya Lake System Neolithic as the reference. Results. The article suggests that the research of Taiga area sites, in particular Kondinskaya lowland, is the best approach to solve the main issues of flat-bottomed Neolithic of trans-Ural region in the actual conditions. In spite of its poor state of knowledge, the North of Western Siberia shows a relative stability of cultural tradition development. Synchronic and diachronic aspects of a zoned existence of round, pointed and flat bottomed Neolithic ceramic assemblages in the Taiga zone of Western Siberia is presented. Conclusion. The paper analyses the stratigraphic situations on the sites and objects in North-West Baraba (Tartas-1, Ust-Tartas, Avtodrom-1 and 2) which proves the early age of the Neolithic assemblages with flat-bottomed ware. This allowed to draw the conclusion about the identical development processes in the Neolithic of Trans-Ural and Baraba.

Full textAbstract:
According to the data collected in the second half of summer for the period from 1954 to 2016 in the flat and mountainous parts of Western Siberia, the distribution and number of the narrow-headed vole in the zonal and provincial aspects were analyzed. Based on the cluster analysis of the matrix of similarity coefficients of abundance indicators obtained by averaging the initial data by years and groups of geobotanical maps units, the classification of habitats according to the favorable environmental conditions degree for the vole is made. The averaged samples are divided into five types of favorability: from optimal, where the abundance of the species is highest in the whole studied area, to extreme, where it is not encountered. In the South of the West Siberian plain narrow-headed vole prefers steppes, and in the subarctic tundras – communities of river valleys. In the Altai and Kuznetsk-Salair mountain regions it is most common in the subalpine light forests, tundras and tundra-steppe of the North-Western and SouthEastern Altai. On average, this vole prefers open habitats in Western Siberia. According to the classification and the structural graph, the dependence of the vole abundance on a number of factors and their inseparable combinations (enviromental and anthropogenic regimes) was revealed. The greatest connection with its distribution in the habitats of Western Siberia is traced for heat and water availability. On the plain, the number of this vole increases from the middle taiga, where it is found only once, to the subzone of the subarctic tundras in the North and to the forest-steppe and steppe zones in the South. In the mountains its more in the South-Eastern Altai, where a relatively high proportion of the most favorable for narrow-headed vole habitats.

Full textAbstract:
<em>Gentiana septemfida</em> Pall. is a montane species native to the Caucasus, Asia Minor, and Western Siberia. This protected plant species from the Siberian flora has significant medicinal and ornamental value. Field studies were conducted in the forest zone of the West Siberian Plain (Tomsk Region) and in the Altai highlands (Seminsky, Kuraisky and North Chuysky ridges of the Republic of Altai). It was found that the distribution of<em> G. septemfida</em> in the southern part of Western Siberia is closely associated with meadow cenoses. In the Altai Mountains, this species occurs near the upper boundary of the forest belt, in forest meadows, open glades, and bushy tundra with alpine and subalpine forbs. In the flat landscape, it is rarely encountered in river valleys among mesophilic tall grass meadows. The studied coenopopulations of <em>G. septemfida</em> are characterized as normal type, incomplete, ripening or mature. By morphological features were showed that coenopopulations from Seminsky Ridge and Tomsk Region have the most optimal conditions for plant growth and development. In nature, <em>G. septemfida</em> reproduces by seeds. However, in some areas seed productivity significantly reduced due to annual damage of fruits by insect pests. The lowest level of the reproductive potential was in Seminsky Ridge coenopopulation. The assessment of plant introduction in the southern part of the Tomsk Region classified <em>G. septemfida</em> as a stable plant. The gene pool established in the Siberian Botanical Garden, Tomsk State University, plays a crucial role in successful conservation of the species in ex situ conditions.

Full textAbstract:
The paper is the first approach to study the etymology of the lower reaches of the river Tavda (northeast of the Nizhnetavdinsky and Yarkovsky districts of the Tyumen region) which bears the imprint of an early encounter of the Russian language with the languages of “foreigners”– the Turks and the southern Ugric peoples on the West Siberian territory. The etymological interpretation of the lower Tavda river hydronymic material is very difficult due to its long and complex development in the context of the Ob-Ugric-Turkic-Russian contacts. The names of local rivers and lakes reflect the history of Russian settlement of the region after Yermak’s “Tavda campaign,” but apart from this North Russian trace, they also showcase a number of substrate and adstrate phenomena that are signs of the contact with the indigenous population. Studying the history of the Russian development of the lower reaches of the Tavda allows one to restore the general linguo-ethnic picture of the hydronymy of the region, in which the Russian, Turkic, and Ob-Ugric layers are distinguished. The paper explores the etymologies of the Turkic hydronyms Iska, Kinder, hybrid Russian-Turkic Maksukul, Ob-Ugric Tavda, Anger, Busalka, Mirtur, Muksuntur. The influence of Russian-Turkic language contacts is reflected in the coexistence of phonetic variants which opens up opportunities for new etymological interpretations (e.g. hydronym Kultybaik). An attempt is made to identify “quasi-substrate” (according to Alexander Matveyev) Ob-Ugric hydronyms, both borrowed in the process of Russian exploration of Siberia (Labuta, Pachenka) and brought from the more western Ural territories (Ashmarka). The use of diverse resources: historical, cartographic (starting with Semyon Remezov’s Chorographic Sketchbook of Siberia), as well as field materials made it possible to propose a number of new etymologies and verify etymological solutions.

Full textAbstract:
On the basis of the materials obtained from the studies carried out from 2000 to 2015, we present the data on distribution of the Yellow Wagtail forms in the north of Western Siberia, i.e. within the overlapping boundaries of the ranges of a complex set of several polytypical forms – Motacilla flava sensu lato. Four forms have been identified here: two forms from the group of Western Yellow Wagtails (M. f. thunbergi and M. f. beema & flava) and two forms from the group of Eastern Yellow Wagtails (M. t. plexa and M. t. tschutschensis). Western “black-headed” form M. f. thunbergi is spread in the area of the northern taiga, forest tundra and south shrub tundra within the Ob River basin, while eastern “black-headed” form M. t. plexa is found in the shrubby tundra and further to the east from the Ob River in forest tundra and northern taiga. Western “light headed” wagtails M. f. beema & flava spread as far as 65º05'N along the floodplain of the Ob River. Eastern “light-headed” wagtail M. t. tschutschensis penetrates the Taz peninsula and, through the anthropogenic sites, the north-east coast of the Yamal Peninsula, i.e. the Sabetta area as far as 71º14'N. The entire range of the Yellow Wagtail is characterized by the interchange of zones inhabited by “black-headed” (without the expressed eyebrows on males) and “light-headed” (with notable eyebrows on males or white-headed) forms from the north to the south.

Full textAbstract:
In this paper, a ceramic complex (groups III and IV) of the early Neolithic settlement of Mergen 6 (Lower Ishim River region, Western Siberia, 7th millennium BC) is examined. The aim of the work is to analyze the mate-rials through the prism of contacts, connections and mixing of different cultural traditions in the early Neolithic period of the Trans-Urals and Western Siberia. The research is based on the elements of the historical-cultural and formal-classification approaches. The source base comprises 284 vessels. As the result of the analysis car-ried out in several stages (morphology of the vessels, tools and techniques for applying ornamentation, structural components of the decor, the nature of the systematic organization of the ornamental components, and relation-ship between the image components and structure of the vessel’s shape), it was found that the products of group III correspond to the tradition of making vessels with relief bands of the taiga zone of Western Siberia and the Urals (Sa-tyginsky, Mulymyinsky types, etc.), whereas those of group IV demonstrate a mixture of all pottery traditions iden-tified within the complex. On this basis, the main directions of the sociocultural ties of the ancient population of the Lower Ishim region in the early Neolithic period have been determined — western (the Middle and Southern Trans-Urals), north-western (the taiga zone of Western Siberia and the southern Northern Trans-Urals), and, probably, southern (the steppes of modern Northern Kazakhstan). One of the most important factors of the vari-ability of the early Neolithic pottery has been identified — the interaction and mixing of different communities. All this allows speaking about the settlement of Mergen 6 as a center (cultural, economic, sacred (?)) at the intersec-tion of landscape and geographical zones (steppe — forest, Trans-Urals — Western Siberia) and ways of disper-sal of various groups of the ancient population.

Full textAbstract:
The study of the hydrological hazards in the north of Western Siberia is important because settlements in this territory are generally located on the banks of rivers and are therefore subject to the negative effects of water. The purpose of this study is to identify the dynamics of hydrological hazards in the settlements of the Konda river basin. The objectives of the study are aimed at identifying hazardous areas, which is necessary to make informed decisions related to rational bank reinforcement. The research object was the settlements of the Khanty-Mansi Autonomous district–Yugra (Kama village, Altay village, Vykatnoy settlement) within the latitudinal flow of the Konda river between 59 and 61 N and between 66 and 70 E, where the manifestation of hydrological hazards is active in nature. Research methods are based on field surveys using satellite geodetic surveying, remote probing, and bed mapping analysis. The data obtained during the study show that the most significant bank line deformations occur within the Vykatnoy, Kama, and Altay areas. The results showed the need for engineering solutions to bank reinforcement and protection of these settlements from the negative impact of river.

Full textAbstract:
Changes in the avifauna of the three large regions of the north of the Yamalo-Nenets Autonomous Okrug (Russia), the Lower Ob River region, the floodplain of the Lower Ob, and the Yamal Peninsula, have been analyzed for a period of more than 60 years. The analysis is based on relative estimates of the number of species on a 4-point scale; cases of significant shifts in the species ranges also have been considered. It is shown that avifaunae in the long term are highly dynamic formations, the process of their changes is of a permanent nature. Its scale is about half of the species composition for 60 years and its directions vary greatly in different regions, depending on the degree of anthropogenic transformation of the territory. Areas with a relatively low anthropogenic impact (the Lower Ob and the Ob floodplain) are characterized by the predominance of the positive trends, mainly expressed in the appearance of new species. Many of them (more than 25% of the modern species composition) have been detected in the Ob floodplain, which indicates the canalization of the penetration process for new species to the north. The Yamal Peninsula region, where the anthropogenic impact associated with domestic reindeer overgrazing is high, is characterized by the predominance of the negative trends in the form of a decrease in the number of typical tundra species.

<p>The research of modern and fossil soils was conducted at three archaeological sites: Nizhniy Kayancha, Novoilinka-3, and Tytkesken-2. Nizhniy Kayancha is a burial ground (dated 5th century BC) situated on the left bank of the Katun River (400-700 m above sea level). An archaeological site is a burial mound with seven mounds which can be visually separated within the site, and which are placed by small chains with 2–3 objects. The south mound of the first group was examined for a phytolith analysis. Еhe Novoilinka-3 settlement (dated 3rd millennium BC) is situated in the north of Kulunda, in the southern part of a hill formed by the false River Burla. The Tytkesken-2 settlement is situated on the verge of the stream Tytkesken, the left tributary of the Katun River, on its second terrace above the flood plain.</p><p>Geobotanical research was conducted in the territory of the archaeological sites under study. Grass phytoliths of modern flora were examined. Soil samples from different layers of the walls of excavation sites were collected. Phytolith extraction was based on the methods described by A.A. Golyeva. 20 g of soil, and 100 g of plant material of each species were processed during the initial period. The examination of the phytoliths of leaves, stalks and flower heads from the samples obtained from the plant material was carried out with the help of an optical microscope (Olympus BX-51). The phytoliths were counted to 250 (in ashed plants) and to 300 (in soils) particles.</p><p>More mesophytic plant communities of the ancient epochs have been reconstructed for all three examined archaeological sites. The territory of the Nizhniy Kayancha burial ground was covered by birch forest at the time prior to formation of the archaeological site. The territory of Novoilinka-3 settlement was covered by pine and birch steppificated forest in the Eneolithic period, but the territory was deforested as the settlement developed. Several stages of vegetation change have been reconstructed for the Tytkesken-2 archaeological site. This includes deforestation of pine forest and further steppe formation in the late Neolithic Age, prairiefication in the Eneolithic Age and new steppe formation in the Bronze Age up to the present time.</p>

The area north of Lake Baikal has been poorly studied. Moreover, most of the studies conducted in this region were focused on mountain ridges or river valleys. This region includes a part of Baikal-Amur Mainline (BAM), a broad-gauge railway in the centre of Siberia, Russia. The railway is an alternative route of the Trans-Siberian Railway; BAM starts in southern Siberia (Taishet station of Irktusk Oblast), passes through the northern part of Lake Baikal and finishes in the Russian Far East (Sovetskaya Gavan station of Khabarovsky Krai). BAM has four connections with the Trans-Siberian Railway and is the centre of economic development for many regions of Russia. Maya Ivanova and Alexandr Chepurnov summarised the existing floristic information for this region in detailed species distribution maps which they published in the book "Flora of the western part of developing regions of Baikal-Amur Mainline (BAM)" (1983). After publishing this book, very few floristic studies have been performed in the study region. All available botanical information is still accumulated in a number of printed papers or books with limited circulation, which are not widely known to the international scientific community.We have digitised the point distribution maps from the book of Ivanova and Chepurnov and georeferenced all occurrence and sampling localities. The resulting dataset includes 9972 occurrences for 770 vascular plant species and subspecies from the area north of Lake Baikal. Additionally, the dataset includes information on the distribution of 43 rare and endangered species with 366 occurrences. From our point of view, the dataset makes a contribution to the global biodiversity data mobilisation, providing plant species distribution data for such a remote mountainous area.

Abstract. Analysing the genesis of Quaternary sediments is important for understanding the glaciation history and development of marine sediments in the northern part of Western Siberia. The problem is relevant since there is no consistent concept of the Quaternary sediment genesis in the north of Western Siberia. The formation of sediments is associated with marine, glacial and interglacial sedimentation conditions. The research objective is to identify the persistent features characterising the conditions of sedimentation and relief formation using the Nadym River basin as an example. The best method for studying this problem is a comprehensive analysis of the lithological, chronostratigraphic, petrographic and geomorphological studies of the Quaternary sediment upper strata. This study provides data from the analysis of the basic characteristics of quartz grains at the site. The rounding and morphology of the quartz grains provide evidence of possible glacial processing of some of the site strata. A petrographic study of selected boulder samples was performed. Some of them, by the shape and presence of striation, can be attributed to ice basins. The first use of a detailed digital elevation model applied to the study area made it possible to identify specific relief forms that could very likely be created during glaciations. Based on the analysis, we propose to consider the vast lake alluvial plains in the Nadym River basin as periglacial regions. This idea lays the lithological framework for understanding the reasons for the formation of the modern landscape structure. The materials and descriptions provided are of interest to researchers of Quaternary sediments, topography, vegetation and soil cover, particularly researchers engaged in revising the history of the natural environment development in the north of Western Siberia.

Full textAbstract:
The article contains systematic information about the process of resettlement of dispossessed peasants to the North of Western Siberia during the 1930s. It is alleged that this was the first stage of peasant exile, which began in February 1930. In total, researchers distinguish three stages (1930-1933). Based on documents and scientific publications, plans for the resettlement of dispossessed peasants to the Tobolsk North is discussed in the article. Features of preparation for the resettlement of “kulaks” and members of their families to the North by the example of agricultural districts of the Ural region are disclosed. The novelty of the study is that the author by comparative analysis reveals the number of peasants to be evicted, as well as the number of peasants who appeared in the Tobolsk north by the end of 1930. Particular attention is paid to the processes of transporting “kulaks” in two stages: in winter, and also in spring et summer (in navigation) in 1930. For the first time, data on the number of peasants delivered by river transport to the North is presented. The names of steamboats, the number of barges that transported people, places of settlement are reported. Statistics on the ratio of the number of local population and special settlers in the Yamalo-Nenets and Khanty-Mansiysk districts is provided. Digital data allow the author to conclude that the North of Western Siberia has become a region of increased concentration of special groups of population.

The paper characterizes the location, density (density), economic and socio-cultural development of the network of rural settlements of the Ostyako-Vogul and Yamalo-Nenets national districts according to data for 1935-1936. The subject of the study is the rural settlement network of the named districts, the object is the location, density of the settlement network, its industrial, economic and socio-cultural infrastructure. In the study, statistical data collected by the Omsk Regional Department of National Economic Accounting (OBLUNKHU) were used as the main source Gosplan of the USSR on key indicators of economic and cultural development of the administrative-territorial units of the region, including the districts of North-Western Siberia. The dependence of the density of the settlement network on the natural and climatic zone, the peculiarities of the management of the local population is shown. The territories of sparse and relatively dense settlement within the boundaries of the national districts under consideration are determined, indicators of economic and socio-cultural development of settlements are presented. As results of the study author presents the conclusions about the dispersion of settlement in the polar tundra zone, the presence of territorial concentrations of rural settlements in the forest tundra and taiga zones not around administrative and economic centers, but along important transport arteries, the role of which in the north of Western Siberia was mainly performed by rivers. The predominance of the simplest industrial associations as the most common form of collective farms in the region is noted, positive changes in the development of the socio-cultural infrastructure of rural settlements of the region are recorded.

Full textAbstract:
The assessment of riverine fluxes of carbon, nutrients, and metals in surface waters of permafrost-affected regions is crucially important for constraining adequate models of ecosystem functioning under various climate change scenarios. In this regard, the largest permafrost peatland territory on the Earth, the Western Siberian Lowland (WSL) presents a unique opportunity of studying possible future changes in biogeochemical cycles because it lies within a south–north gradient of climate, vegetation, and permafrost that ranges from the permafrost-free boreal to the Arctic tundra with continuous permafrost at otherwise similar relief and bedrocks. By applying a “substituting space for time” scenario, the WSL south-north gradient may serve as a model for future changes due to permafrost boundary shift and climate warming. Here we measured export fluxes (yields) of dissolved organic carbon (DOC), major cations, macro- and micro- nutrients, and trace elements in 32 rivers, draining the WSL across a latitudinal transect from the permafrost-free to the continuous permafrost zone. We aimed at quantifying the impact of climate warming (water temperature rise and permafrost boundary shift) on DOC, nutrient and metal in rivers using a “substituting space for time” approach. We demonstrate that, contrary to common expectations, the climate warming and permafrost thaw in the WSL will likely decrease the riverine export of organic C and many elements. Based on the latitudinal pattern of riverine export, in the case of a northward shift in the permafrost zones, the DOC, P, N, Si, Fe, divalent heavy metals, trivalent and tetravalent hydrolysates are likely to decrease the yields by a factor of 2–5. The DIC, Ca, SO4, Sr, Ba, Mo, and U are likely to increase their yields by a factor of 2–3. Moreover, B, Li, K, Rb, Cs, N-NO3, Mg, Zn, As, Sb, Rb, and Cs may be weakly affected by the permafrost boundary migration (change of yield by a factor of 1.5 to 2.0). We conclude that modeling of C and element cycle in the Arctic and subarctic should be region-specific and that neglecting huge areas of permafrost peatlands might produce sizeable bias in our predictions of climate change impact.

Full textAbstract:
The article studies the technology of making iron and steel items of Russian origin, discovered in the Kikki-Akki burial ground of Northern Selkups (18th–19th centuries) in the north of Western Siberia in the upper reaches of the Taz River. In the study, we established the origin and chronology of Russian industrial goods in Western Siberia, as well as factors under the influence of which they appeared among the indigenous Siberian population. We examined knives and axes (17th — early 19th centuries) using the methods of metallographic analysis includ-ing macro- and micrographic examination, as well as microhardness testing. They provide an opportunity to de-termine the structure of the metal, which in turn helps determine chemical composition, physical and mechanical properties of the product. The analysis of forged products revealed that they were made according to the techno-logical traditions of Russian metalworking production existing in the 17th — early 19th centuries. Its distinctive features included the development and widespread practice in applying the modifications of two technological schemes for producing items from ferrous metal. The former was based on the welding either of iron and steel or of different grades of steel, whereas the latter involved all-steel structures. The former technological scheme pre-dominated in the production of items found in the Kikki-Akki burial ground. Moreover, the production of welded structures lacked standardisation. The following techniques were used in the production of knives: two-layer wel-ding of iron and steel, three-layer welding, V-joint welding, oblique welding, built-up welding at the ends and wel-ding of the steel blade. The use of soft quenching was noted as an additional operation that improved the opera-tional properties of the household tool. This variety of used technological schemes reflects the complex nature of the formation of the industrial goods market in Western Siberia. The selection of items made using different welded technologies is associated with the intention to use metal products of the highest quality for the fur trade and yasak collection. However, all-metal structures predominated in the main centres for the production of forged goods — cities of European Russia and Western Siberia.

Full textAbstract:
In 2020, the expedition of Poengurr and the Institute of History and Archaeology of the Ural Branch of RAS investigated the settlement of Tolum-1, which functioned during the Neolithic, Eneolithic, Bronze and Early Iron Ages. The site is located in the north of Western Siberia, in Kondinsky District of Khanty-Mansi Autonomous Ok-rug — Yugra. Structure (dwelling) No. 3 containing a complex of stone tools and pottery of the Enyi type, as well as the adjoint area, were investigated by an excavation trench of an area of 499 m2. On the settlement, 108 stone items were found, the large part of which concentrates within the boundaries of dwelling No. 3. The research is based upon the method of technical and typological analysis of stone-tool assemblage, implying the development of a typology of stone tools and the study of their production technology taking into account the quality of the or-namental raw materials used by the ancient population. According to the raw-material composition of the stone-tool assemblage, mainly represented by soft rocks (grey-green slate, burgundy schist, etc.) and, to a lesser ex-tent, by flint of various colors, quartz and quartzite, the ancient population of this region did not have continuous sources of high-quality ornamental raw materials. Prevailing on the settlement are the tools for woodworking (drillbit-shaped tools, adzes, chisels), and also found were knives and a representative collection of arrowheads. Items for stone processing are few: a hammer-stone, a retoucher, and two cores. There is a higher presence of unprocessed pebbles and tiles, and chips and fragments of polished products. The main technological chain on the site was production of polished tools from local gray-green slate by chipping off and subsequent grinding. The production of flint tools by splitting and retouching was insignificant. The stone assemblage of the Tolum-1 settle-ment finds analogies in the complexes of the Enyi type of the north of Western Siberia. Certain categories and types of products are more widespread — double-sided retouched fish-shaped arrowheads are found in quantity in the Trans-Urals, polished leaf-shaped arrowheads with a groove — in the Eneolithic sites of the north of Wes-tern Siberia, while polished arrowheads with a tapered truncated base were found among the Eneolithic materials of the Surgut Ob Basin and on the sites with the Ushya ceramics of the Neolithic Period of the Konda lowland. Polished rounded and teardrop-shaped pendants are found in the funerary and, to a lesser extent, settlement complexes of the Trans-Urals and Western Siberia in the Late Neolithic — Eneolithic. A series of radiocarbon dates obtained for the settlement of Tolum-1 and other sites of the Enyi type in the north of Western Siberia, as well as the technical and technological characteristics and morphology of the stone inventory of the settlement under consideration, and a wide range of analogies leave open the possibility of attributing the structure No. 3 to the Eneolithic Period, within the span of the calibrated dates in the interval of 3600–2600 BC.

Migratory connections in waterfowl in the north of Western Siberia are discussed as based on ring recoveries from the database of the Bird Ringing Center of Russia, A.N. Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences. Altogether, 3531 recoveries from waterfowl of 29 species were used. The waterfowl in the region are characterized by exceptionally wide migratory connections, occurring in different seasons in most regions of the Old World within the Northern Hemisphere: from Iceland to the Japanese Islands and from West Africa to the Indian Subcontinent and the Yangtze River basin. The long-distance flights of birds to molting sites, the interannual change of nesting grounds and wintering regions, as well as the distribution on wintering grounds are discussed. Ten wintering regions have been allocated. The available material on the migration of waterfowl is evaluated from the viewpoint of completing the description of their seasonal distribution and its significance in the study of ecological connections of the territory of Western Siberia.

In fact, when we look at the Turkish epics and written documents of the Irtysh River tribes, BC. It is a geography where Turks have lived and settled since ancient times. After the disintegration of the Göktürk Khaganate, of which the Kipchaks were an important element, it is seen that the Kimek clan united in Western Siberia, which was under its dominance, and then spread to the wide steppe area. Senior Siberian researcher M. A.

Consider the Kuchum Khan Empire, which has hitherto been the only Finnish state, as a suitable subject to study. Kuchum Khan himself was a Turk, but his effort in resisting Yermak and the relations of these two heroes are really worth processing in the poem," he wrote. The research results of the Castren era have since been repeatedly censored. Key words: Siberya,Ural-Altai, Kimek-Kipchaks, Kuchun Khan, Russian Attack, Censorhip.

Abstract. We analyze 48 geothermal estimates of Pleistocene/Holocene warming amplitude from various locations in Greenland, Europe, Arctic regions of Western Siberia, and Yakutia. The spatial distribution of these estimates exhibits two remarkable features. (i) In Europe and part of Asia the amplitude of warming increases towards northwest and displays clear asymmetry with respect to the North Pole. The region of maximal warming is close to the North Atlantic. A simple parametric dependence of the amplitude on the distance to the warming center explains 91% of the amplitude variation. The Pleistocene/Holocene warming center is located northeast of Iceland. We claim that the Holocene warming is primarily related to the formation (or resumption) of the modern system of currents in the North Atlantic. (ii) In Arctic Asia, north of the 68-th parallel, the amplitude sharply decreases from South to North, reaching zero and even negative values. Too small amplitudes could be attributed to a joint warming influence of Late Pleistocene ice sheets and warm-water lakes formed in Late Pleistocene by the damming of the Ob, Yenisei and Lena Rivers. Using a simple model of the temperature regime underneath the ice sheet we show that, depending on the relationship between the heat flow and the vertical ice advection velocity, the base of the glacier can either warm up or cool down.

A 900-Years Larch Chronology for North-Western Siberia on the Bases of Archaeological Wood of the UST-Voykar SettlementDuring 2003-2006 summer excavation seasons of the Ust-Voykar settlement (65°40' N, 64°30' E) located in northwestern Siberia on the left bank of Gornaya Ob river, 121 samples of larch were collected. Living trees collected nearby were used to cross-date settlement construction. On the basis of living larch trees a 446 year (1554-1999) chronology has been constructed. Calendar dates for 101 samples of archaeological wood were established by cross-dating. Together, the living and archeological material result in a 903 year long chronology. This chronology shows similar variations as the Yamal and Polar Ural chronologies and provides new material that can be included in future climatic reconstructions.

Abstract. In contrast to numerous studies on the dynamics of dissolved (<0.45 µm) elements in permafrost-affected high-latitude rivers, very little is known of the behavior of river suspended (>0.45 µm) matter (RSM) in these regions. In order to test the effect of climate, permafrost and physio-geographical landscape parameters (bogs, forest and lake coverage of the watershed) on RSM and particulate C, N and P concentrations in river water, we sampled 33 small and medium-sized rivers (10–100 000 km2 watershed) along a 1700 km N–S transect including both permafrost-affected and permafrost-free zones of the Western Siberian Lowland (WSL). The concentrations of C and N in RSM decreased with the increase in river watershed size, illustrating (i) the importance of organic debris in small rivers which drain peatlands and (ii) the role of mineral matter from bank abrasion in larger rivers. The presence of lakes in the watershed increased C and N but decreased P concentrations in the RSM. The C:N ratio in the RSM reflected the source from the deep soil horizon rather than surface soil horizon, similar to that of other Arctic rivers. This suggests the export of peat and mineral particles through suprapermafrost flow occurring at the base of the active layer. There was a maximum of both particulate C and N concentrations and export fluxes at the beginning of permafrost appearance, in the sporadic and discontinuous zone (62–64∘ N). This presumably reflected the organic matter mobilization from newly thawed organic horizons in soils at the active latitudinal thawing front. The results suggest that a northward shift of permafrost boundaries and an increase in active layer thickness may increase particulate C and N export by WSL rivers to the Arctic Ocean by a factor of 2, while P export may remain unchanged. In contrast, within a long-term climate warming scenario, the disappearance of permafrost in the north, the drainage of lakes and transformation of bogs to forest may decrease C and N concentrations in RSM by 2 to 3 times.

Abstract. Natural and anthropogenic mercury (Hg) emissions are sequestered in terrestrial soils over short, annual to long, millennial timescales before Hg mobilization and run-off impact wetland and coastal ocean ecosystems. Recent studies have used Hg-to-carbon (C) ratios (RHgC's) measured in Alaskan permafrost mineral and peat soils together with a northern circumpolar permafrost soil carbon inventory to estimate that these soils contain large amounts of Hg (between 184 and 755 Gg) in the upper 1 m. However, measurements of RHgC on Siberian permafrost peatlands are largely missing, leaving the size of the estimated northern soil Hg budget and its fate under Arctic warming scenarios uncertain. Here we present Hg and carbon data for six peat cores down to mineral horizons at 1.5–4 m depth, across a 1700 km latitudinal (56 to 67∘ N) permafrost gradient in the Western Siberian Lowland (WSL). Mercury concentrations increase from south to north in all soil horizons, reflecting a higher stability of sequestered Hg with respect to re-emission. The RHgC in the WSL peat horizons decreases with depth, from 0.38 Gg Pg−1 in the active layer to 0.23 Gg Pg−1 in continuously frozen peat of the WSL. We estimate the Hg pool (0–1 m) in the permafrost-affected part of the WSL peatlands to be 9.3±2.7 Gg. We review and estimate pan-Arctic organic and mineral soil RHgC to be 0.19 and 0.63 Gg Pg−1, respectively, and use a soil carbon budget to revise the pan-Arctic permafrost soil Hg pool to be 72 Gg (39–91 Gg; interquartile range, IQR) in the upper 30 cm, 240 Gg (110–336 Gg) in the upper 1 m, and 597 Gg (384–750 Gg) in the upper 3 m. Using the same RHgC approach, we revise the upper 30 cm of the global soil Hg pool to contain 1086 Gg of Hg (852–1265 Gg, IQR), of which 7 % (72 Gg) resides in northern permafrost soils. Additional soil and river studies in eastern and northern Siberia are needed to lower the uncertainty on these estimates and assess the timing of Hg release to the atmosphere and rivers.

Full textAbstract:
The first part of the article published in this journal considers the archaeological context along with the func-tional, morphological and social aspects associated with cauldrons in the cultural traditions of the Ob Ugrians and Samoyeds of North-Western Siberia. In this work, the authors analyse field ethnographic materials collected from the Khanty (Synya, Voykar, Sob, Kunovat, Polui, Ob, Salym, Yugan, Pim, Tromyogan, Agan, Vakh, Polar Urals), Mansi (Northern Sosva, Lyapin and Lozva Rivers) and Nenets (Yamal Peninsula, Pur and Agan Rivers) in 1980–2018. The study of cauldrons in a ‘living’ culture along with analysing them as an archaeological artefact has greatly expanded the chronological range of the research from the 1st–4th centuries AD to the present time. The archaeological and ethnographic research is based on a structural and semiotic approach. A cauldron, as an ele-ment of material and spiritual culture, associated with the methods for obtaining and preserving energy, is directly related to the experience of using natural resources and to the development of life sustenance models for the Northern communities. Numerous archaeological discoveries of intact cauldrons, as well as their fragments and items made from their fragments in North-Western Siberia, indicate the archaism and the continued use of caul-drons as vessels for storage and cooking; fashionable, prestigious, high-status items; a receptacle for the soul; a divine attribute and a talisman, etc. It is not surprising that the cauldron, whose direct purpose consists in storage and preparation of food, is incredibly versatile in Ob-Ugric and Samoyedic cultures. The cauldron appears in the surviving toponyms and legends of the Nenets, Khanty and Mansi. It acts as a measure of volume and time. Cauldrons possess features and properties of a living organism; they contain the energy of fire and stone-iron. The ability of cauldrons to change their condition and position (full/empty, boiling/not boiling, upside-down/right-side-up) is manifested in their diverse duality making them mediators in the following juxtapositions: peace —enmity, familiar — alien, kinship — property, birth — death, wealth — poverty, happiness— trouble. А cauldron is a symbol of family unity, the source of the power for birth-recovery, as well as an attribute of shamanic rites and a border between the worlds. The high mythical and ritual status of the cauldron is emphasised by its celestial ori-gin.

Full textAbstract:
North China and South Siberia, populated by Altaic- and Sino-Tibetan-speaking populations, possess extensive ethnolinguistic diversity and serve as the crossroads for the initial peopling of America and western–eastern transcontinental communication. However, the population genetic structure and admixture history of northern East Asians remain poorly understood due to a lack of genome-wide data, especially for Mongolic-speaking people in China. We genotyped genome-wide single nucleotide polymorphisms for 510 individuals from 38 Mongolic, Tungusic, and Sinitic-speaking populations. We first explored the shared alleles and haplotypes within the studied groups. We then merged with 3508 published modern and ancient Eurasian individuals to reconstruct the deep evolutionary and natural selection history of northern East Asians. We identified genetic substructures within Altaic-speaking populations: Western Turkic people harbored more western Eurasian-related ancestry; Northern Mongolic people in Siberia and eastern Tungusic people in Amur River Basin (ARB) possessed a majority of Neolithic ARB related ancestry; Southern Mongolic people in China possessed apparent genetic influence from Neolithic Yellow River Basin (YRB) farmers. Additionally, we found the differentiated admixture history between western and eastern Mongolians and geographically close Northeast Hans: the former received a genetic impact from western Eurasians, and the latter retained the primary Neolithic YRB and ARB ancestry. Moreover, we demonstrated that Kalmyk people from the northern Caucasus Mountains possessed a strong genetic affinity with Neolithic Mongolian Plateau (MP) people, supporting the hypothesis of their eastern Eurasian origin and long-distance migration history. We also illuminated that historical pastoral empires in the MP contributed considerably to the gene pool of northern Mongolic people but rarely to the southern ones. We finally found natural selection signatures in Mongolians associated with alcohol metabolism. Our results demonstrated that the Neolithic ancestral sources from the MP or ARB played an important role in spreading Altaic populations and languages. The observed multisources of genetic diversity contributed significantly to the extensive ethnolinguistic diversity in northern East Asia.

Abstract The purpose of this article is to examine Khanty spatial ritual behaviour in the context of the simultaneous application of different ideas about sacred landscape. I aim to demonstrate the functional pattern behind handling seemingly ambivalent characteristics of cosmological models in the tangible ritual performance of the Khanty, an indigenous people inhabiting the taiga and forest taiga zone of Western Siberia. I explore three cases in which the concept of sacred topography is applied among the Khanty by exploring two public ceremonies of reindeer sacrifice and one episode of a post-funeral rite. It appeared that the spatial conceptualisation is different in different rituals. During sacrificial ceremonies, the Khanty position the Upper World in the southern direction, while in the case of death rituals, the Upper World is projected towards upstream of a river, even if it remains in the north. Studying different spatial orientations during rituals provides a methodological key for approaching other concepts of vernacular belief among Siberian indigenous communities.

The article is devoted to the reconstruction of historical contacts of the Mansi language with Samoyedic languages. On the modern linguistic map of Western Siberia these languages are not in direct contact, however, linguistic data make it possible to reconstruct several contact situations of varying degrees of temporal depth. I suppose that in the region of the Upper Ob there was a historical linguistic area, which included the Mansi, Selkup, and Kamas languages. In the eastern periphery of this zone, some limited contacts between the Selkups and the Kets took place. The Khanty language was widespread north of the Mansi language, possibly, in the northern periphery of this area. The ancestor of the modern Eastern Khanty language was located closest to the Mansi language. The Mansi contacted with the speakers of the Southern Samoyedic languages most probably across the rivers of Chizhapka and Parabel. Within the same area E. G. Bekker identifi ed the zone of distribution of the Kamas toponymy. During the period of these contacts, in my opinion, Kamas and Selkup were already two separate languages, but the dialectal diff erentiation of Selkup had not yet begun: the article proposes a number of Mansi-Selkup areal isoglosses, equally represented in all Selkup dialects. Subsequently, the relative position of the Khanty and Mansi languages on the linguistic map of Western Siberia changed. The Eastern Khanty penetrated the Upper Ob area. Then the Northern and Southern Khanty settled in a wide zone stretching from north to south along the course of the Middle Ob and Irtysh. This interrupts the connection between the Mansi and the Eastern Khanty and cuts off the Mansi from the Upper Ob area. During this period, the modern “Ostyak” area including the Selkup, Ket, and Khanty languages began to form in the Upper Ob region. The formation of this “Ostyak” area should be attributed to the period after the dialectal differentiation of the both mentioned Uralic languages: this area includes only the easternmost dialects of Khanty and only the Northern and Tym dialects of Selkup.

Full textAbstract:
For the first time, a complete annotated list of vascular plant species is provided and the local flora (LF) “Burulginsky Cape” is analyzed. It is the richest known LF in the lower reaches of the Indigirka River (262 species and subspecies, 109 genera, 41 families), including a number of the species rare in the northern Yakutia and seven species listed in the regional Red Book, as well as taxa endemic to the Arctic ×Trisetokoeleria jurtzevii Probat. and ×T. taimyrica Tzvel. The similarity of the studied flora with LFs from the East Siberian and Chukotka provinces of the Arctic floristic region (lower reaches of the Anabar, Lena, Indigirka, Kolyma Rivers, and Western Chukotka) is discussed; its type is determined as the East Siberian hypoarctic flora, with a predominance of mesophytes in its composition and with a noticeable participation of the species of arid habitats. The territory of the Burulginsky Cape LF with an area of about 200 km2 is recommended to include in the category of specially protected objects as an area of increased diversity of vascular plants.

Full textAbstract:
Genetic and archaeological evidence imply a second major movement of Neanderthals from Western to Central and Eastern Eurasia sometime in the Late Pleistocene. The genetic data suggest a date of 120−80 ka for the dispersal and the archaeological record provides an earliest date of arrival in the Altai by ca. 60 ka. Because the number of archaeological sites linking the two regions is very small, the exact route taken and its timing have been the matter of considerable debate. In particular, climate change in this period modified landscapes considerably, changing the cost of moving in different directions. Here, we apply agent-based least-cost path simulations for the first time to Neanderthals, showing that they most likely took a northern route through the Urals and southern Siberia under all climate scenarios. Agents leaving either the southern or the northern Caucasus Mountains reach the Altai in less than 2000 years during two time windows when the climate was mild, in MIS 5e (the Last Interglacial) and in MIS 3. The latter coincides with the dated presence of Neanderthals at Chagyrskaya and Okladnikov Caves in the Altai. The results of this modeling approach demonstrate a remarkable east-west geographic connectivity of northern Eurasia via river corridors despite the presumed barriers of the Ural Mountains and major north-south flowing rivers. Our results highlight the unique strengths of agent-based simulations to reconstruct pathways for ancient migrations.

Full textAbstract:
For more than half a century, the question remained unresolved why the closely spaced sequences of fluvial sands overlying Middle Pleistocene diamicton in the lower reaches of the Ob’ River near the village Khashgort contain micromammal faunas of different evolutionary levels. The sequences 430 and 430a at kilometer 430 from the Ob’ River mouth yielded Late Quaternary faunas and the sequence Khashgort (= Bolshaya Ob’ 440 km) at kilometer 442 from the Ob’ River mouth yielded Middle Quaternary faunas. This contradicted generally accepted ideas, according to which the absence of Middle Quaternary alluvium was assumed in this area and called into question either geological or paleontological interpretations of the Pleistocene history of north of Western Siberia. This paper proposes a comparison between two geological sections using both geological and paleontological methods and suggests an updated biostratrigraphic interpretation of the materials relevant to the Karginian and Tazovian horizons of Western Siberia collected in 1980s and 2016–2022. It is established that the Late Quaternary assemblage of micromammals from the sections at kilometer 430 of the Ob’ River is confined to alluvium of the 2nd terrace above the river floodplain. In the locality Khashgort (Bolshaya Ob’ 440 km) at kilometer 442 of the Ob’ River, the micromammal assemblage is associated with fluvioglacial sands showing the signs of close redeposition of paleontological materials with the outliers comprised in the Middle Quaternary Khashgort aleuropelites bearing boulders and sands. Thus, the study makes it possible to harmonize the geological and paleontological data that were in conflict for more than half a century.

Full textAbstract:
The inland aquatic ecosystems play a significant role in the global carbon cycle, owing to the metabolism of terrestrially derived organic matter as it moves through fluvial networks along the water continuum. During this transport, dissolved organic matter (DOM) is microbial processed and released into the atmosphere, but the degree and intensity of this processing vary greatly both spatially and temporally. The Western Siberian Lowlands is of particular interest for a quantitative assessment of DOM biodegradation potential because the global areal-scale effects of DOM biodegradation in abundant surface organic-rich waters might be the highest in this region. To this end, we collected water samples along a typical aquatic continuum of the Bakchar Bog (the north-eastern part of the Great Vasyugan Mire) and, following standardized protocol, conducted an experimental study aimed at characterizing the seasonal and spatial variability of dissolved organic carbon (DOC) biodegradability. The biodegradable DOC fraction (BDOC) over the exposure incubation period ranged from 2% to 25%. The natural aquatic continuum “mire–forest–stream–river” demonstrated the systematic evolution of biodegradable DOC among the sites and across the seasons. The highest biodegradation rates were measured during spring flood in May and decreased along the continuum. The maximum possible CO2 production from DOM yielded the maximum possible flux in the range of 0.1 and 0.2 g C-CO2 m−2 day−1 d, which is an order of magnitude lower than the actual net CO2 emissions from the inland waters of the WSL. This study suggests that although the biodegradation of the humic waters of the WSL can sizably modify the concentration and nature of the DOM along the aquatic continuum, it plays only a subordinary role in overall C emissions from the lakes and rivers of the region.

In this article, we aim to determine the dynamics of the position of a territory in the structure of communica-tion network, the transport system of the region, to assess the degree of accessibility for the settlements located in the borderzone in the basin of the Lyapin and Nadym Rivers (North-Western Siberia), and to identify the prob-lems related to the low accessibility of residence areas. The sources for the research were the authors' fieldwork materials, acquired during the expeditions to the Berezovsky district of the Khanty-Mansi Autonomous Region of Ugra (2012, 2018, 2019) and Nadym district of the Yamalo-Nenets Autonomous Region (2017, 2019). It has been revealed that, during the 20th century, there was a gradual change in the status of the settlements — they ceased being transit centres on important for Siberia trade routes. Despite the qualitative change in travel technologies from the beginning of the 20th century, residents of remote settlements are limited in their movements, which is associated with the inaccessibility and cost of travel. The reason behind this is the lack of roads, railways, perma-nent navigable waterways, and distance from transport hubs. The transportation network, linked to industrial set-tlements and cities, creates conditions for territorial inequality, socio-territorial stratification and socio-economic asymmetry. An important resource for inhabitants of these poorly accessible areas are waterways and frozen soils, which allow building and using of the so-called winter roads that can be operated only in winter conditions.

Full textAbstract:
In the last decade, in the north of Western Siberia, the authors carried out a large amount of comprehensive research, which made it possible to obtain fundamentally new information about the gas-dynamic mechanisms of dangerous processes in the Arctic permafrost. According to remote sensing data, at the bottom of thermokarst lakes, rivers and coastal zones of the Kara Sea, more than 4.5 thousand zones of powerful gas blowouts with the formation of craters (pockmark) were found. There are reasons to believe that powerful gas emissions mainly come from shallow deposits with ultrahigh (superlithostatic) pressures. For the first time, large mud volcanic uplifts with pronounced craters have been found at the bottom of the Arctic thermokarst lakes. Based on the monitoring of the ice situation and the water environment on the basis of retrospective satellite images on lakes Otkrytie, Labvarto and Yambuto, the presence of periodic emissions of formation fluids, including gas, is shown. Based on the combination of a number of features, the discovered objects can be classified as active mud volcanoes with a high level of probability. The results of the studies allow us to state that mud volcanism is widespread in the Circum-Arctic megaregion.

Some new to the flora of the Yaman Peninsula centric diatoms (Cyclotella meduanae, C. schumannii, Pliocaenicus costatus, Thalassiosira incerta) and the pennate Fragilaria famelica are recorded from waterbodies and water courses in the Far North of Western Siberia. The findings of these species beyond the Polar Circle clarify data on their habitats and ecology. The new species Fragilaria strelnikovae Genkal et Yarushina sp. nov. is described from the Naduiyakha River basin.

Full textAbstract:
In reservoirs and watercourses of the Upper Ob basin (south of Western Siberia) two representatives of the family Valvatidae (Valvatidae) of the subgenus Sibirovalvata, having a planispiral shell, have been noted. It is shown that two species of planispiral mollusks from this subgenus live in the region: Valvata (Sibirovalvata) frigida and V. (S.) sibirica. On the material from the Upper Ob basin, significant conchological differences between V. (S.) frigida and V. (S.) sibirica by key morphometric indices. According to the results of comparison with the material from the north of Western Siberia, it was found that the shells of the northern (basin of the Taz River) and southern (basin of the Upper Ob) populations of V. (S.) frigida and V. (S.) sibirica differ very slightly in morphometric indices, which indicates a slight variability of these traits within the range. At the same time, the detected significant differences between the northern and southern populations in the absolute size of the shell can presumably be explained by the conditions of specific habitats. At the same time, a more favorable temperature regime in the south may be offset by a lack of oxygen, including during the summer-autumn low water period.

Martin Waldseemüller’s maps, published in 1507 and 1513 in Strasbourg, are the first maps to bear the name of the new continent, America. They reveal the discovery of the New World by Spanish and Portuguese navigators. None of the researchers, however, have noticed that the same maps of North Asia (the area of present-day Western Siberia) for the first time show a river flowing into the Arctic Ocean. The peculiarity of Western European cartographic sources at the turn of the 15th–16th centuries lies in the fact that the reflection of the world picture was based on the tradition of the geographer Claudius Ptolemy. The desire to publish the “New Ptolemy” prompted the members of the Vosges Gymnasium, where Waldseemüller worked, to combine traditional knowledge of the world with the latest geographical discoveries. The article analyzes the content of Waldseemüller’s maps, provides a comparative analysis of the maps that formed the basis for the creation of these images, and traces the borrowings of data from the German cartographer by subsequent authors of the 16th century. As a result of careful study of inscriptions and legends, the author concludes that the depiction of areas of North Asia on the maps of the German cartographer dates back to the maps of Henry Martell of 1489–1491. A large map of the world by this author is kept at Yale University, but many of its inscriptions have faded or disappeared. The painstaking work of the American researcher Chet van Duzer, who published a monograph on the map in 2019, gave researchers the opportunity to examine the source carefully. The comparison between this map and an earlier round map of Fra Mauro of 1459 suggested that Martell, in his turn, borrowed the image of the North Asian river from this Venetian monk. Thus, the process of borrowing and clarifying the information about the previously unknown river is traced. At the end of the article, the author proves that European cartographers displayed the latest information about the Ob river, which came from Russia.

Dissolved inorganic carbon is an essential component of the carbon cycle, especially in the northern regions, while its loss through water bodies is still rarely included in regional carbon models. The tasks of the work included a detailed coverage of the methodological approach “headspace equilibration” to the study of the concentration of dissolved CO₂in soil and surface waters, as well as the assessment of the range of CO₂concentrations in waters of different genesis in the landscapes of the north of Western Siberia. As a result of the methodological work done, a protocol was developed and presented for measuring the concentration of CO₂in waters by the “headspace equilibration” method with detailed calculations. The concentration of CO₂ in soil (supra-permafrost) and surface waters (river, bog, lake, etc.) ranged from 13 to 2983 µmol/l (274 to 57000 µatm), the vast majority of objects were supersaturated with CO₂ relative to the atmosphere. The maximum values of concentrations are characterized by supra-permafrost soil and bog waters; the minimum is the waters of aquatic ecosystems: thermokarst and forest lakes. The high variability of CO₂concentration in waters necessitates a large number of measurements to obtain adequate estimates.

River floodplains, reaching several kilometers in width, are one of the main landscape features of the Kolyma Lowland. Their relationship with other forms of relief - yedoma, alasses, and fragments of river terraces - is seen clearly in the Bolshaya Kuropatoch'ya River basin, which is located in the Lowland between 156°30' E and 157°15' E. The first radiocarbon dating of the floodplain deposits of the Kolyma Lowland was undertaken in a study of an outcrop on the left bank of the Bolshaya Kuropatoch'ya River (71°40' N, 156°45' E). Here floodplain sediments, represented by the alternating layers of alluvial silt and peat with a total thickness of 5 m, were exposed along a steep bank of an oxbow lake. The radiocarbon results show that the formation of the modern floodplain of the Bolshaya Kuropatoch'ya River began at the end of the Middle Holocene and continued during the Late Holocene to the present. Since the vegetation cover of arctic and subarctic regions is characterized by low pollen productivity, the spore-pollen spectra of modern and fossil plant communities often include an increased amount of pollen from plant species exotic to the Arctic, brought to the site by long-distance wind transport. For a more reliable interpretation of the spore- pollen spectra of the floodplain sediments, an analysis of the modern vegetation in the Bolshaya Kuropatoch'ya River basin and in a coastal area bordering the East Siberian Sea (about 71°05' N) was carried out, accompanied by an herbarium collection. The radiocarbon-dated palynological data indicate the development of the modern Betula-Salix shrub-herbaceous tundra during the second half of the Holocene. The establishment of this vegetation community reflects the replacement of an earlier Betula forest-tundra, which had prevailed in the northern regions of Western Beringia during the Early Holocene and included Duschekia fruticosa and large shrub species of Salix. Such dramatic changes in the vegetation cover were associated with the rise in sea level about 7.000-6.000 years ago, when seas approached modern levels. This change, in turn, led to a decrease in the contrast of summer and winter temperatures and, thus, to a decrease in the continentality of the climate and a significant reduction in the growing season in the coastal regions of the East Siberian Sea.
