Handles of Early Iron Age Cauldrons from Southwestern Siberia

Handles of Early Iron Age bronze cauldrons from southwestern Siberia are described with reference to their ritual meaning. Typological features, such as knobs, arcuate, or square shape, are relevant for dating. Two chronological groups are established: the Tagar (second half of the 1st millennium BC) and Xiongnu-Xianbei (late 1st millennium BC to early 1st millennium AD). The interpretation of handles depends on the context. At settlements (Turunovka-4) and in certain hoards (First Dzhirim) of the Late Bronze Age, they can belong to foundry scrap. However, handles occur in long-term ritual sites such as Aidashenskaya Cave, suggesting a different interpretation. Indeed, at Eastern European forest-steppe sites of the Xiongnu era, handles of cauldrons had been intentionally buried, most often near water sources, where the summer camps of nomadic herders were situated. A similar situation is observed in southwestern Siberia, from the Baraba forest-steppe to the Middle Yenisei valley.

Early Holocene permafrost retreat in West Siberia amplified by reorganization of westerly wind systems

Rapid permafrost degradation and peatland expansion occurred in Eurasia during the Early Holocene and may be analogous to the region’s response to anthropogenic warming. Here we present a 230Th-dated, multiproxy speleothem record with subdecadal sampling resolution from Kyok-Tash Cave, at the modern permafrost margin in the northern Altai Mountains, southwestern Siberia. Stalagmite K4, covering the period 11,400 to 8,900 years before present, indicates an absence of stable permafrost within three centuries of the Younger Dryas termination. Between 11,400 and 10,400 years ago, speleothem δ18O is antiphased between the Altai and Ural ranges, suggesting a reorganization of the westerly wind systems that led to warmer and wetter winters over West Siberia and Altai, relative to the zonally adjacent regions of Northern Eurasia. At the same time, there is evidence of peak permafrost degradation and peatland expansion in West Siberia, consistent with the interpreted climate anomaly. Based on these findings, we suggest that modern permafrost in Eurasia is sensitive to feedbacks in the ocean-cryosphere system, which are projected to alter circulation regimes over the continent.

Sections of the Early 18th Century Ditch at Fort Umrevinsky

This article describes identified sections of an early 18th century ditch at Fort Umrevinsky in the Upper Ob Basin. Such protective structures mark a certain stage in the evolution of military engineering in the era of Peter the Great (1694–1725) in southwestern Siberia. The design of the earliest parts of the preserved ditches allows us to address the influence of European fortification on Early Modern Russian defensive architecture. Several factors affecting the depth and profile of early 18th century ditches at Umrevinsky are discussed. They include seasonality of specialized trenching tools and the adoption and transformation of European fortification principles by 17th and early 18th Russian military engineers. At Umrevinsky, apart from the specific profile of the ditch, specialized tools were revealed, similar to those mentioned in documents on 18th century fortification. Also, specific features of the preserved parts of the ditch mirror the utmost irregularity in adoption of de Vauban’s fortification principles of the Tsardom of Muscovy, including Siberia. Our finds at Fort Umrevinsky supplement the scarce descriptions of Siberian forts in Russian documents.

Plant communities with naturalized Elaeagnus angustifolia L. as a new vegetation element in Altai Krai (Southwestern Siberia, Russia)

Elaeagnus angustifolia L. (Russian olive) is a deciduous small tree or large multi-stemmed shrub that becomes invader in different countries all other the world. It is potentially invasive in some regions of Russia. In the beginning of 20th century, it was introduced to the steppe region of Altai Krai (Russia, southwestern Siberia) to prevent wind erosion. During last 20 years, Russian olive starts to create its own natural stands and to influence on native vegetation. This article presents the results of eco-coenotic survey of natural plant communities dominated by Elaeagnus angustifolia L. first described for Siberia and the analysis of their possible syntaxonomic position. The investigation conducted during summer season 2012 in the steppe region of Altai Krai allows revealing one new for Siberia association Elytrigio repentis–Elaeagnetum angustifoliae and no-ranged community Bromopsis inermis–Elaeagnus angustifolia which were included to the Class Nerio–Tamaricetea, to the Order Tamaricetalia ramosissimae. During the study, the following special features of communities have been described: polydominance of herbal layer, anthropogenic and grazing load, variation of the species richness, plant cover and vertical stratification into layers. These peculiarities mostly prove unestablished character of communities, all of them are relatively young (25–30 years). Russian olive shrubberies varies in moisture and saline regime, which connected with their existence in different landforms (lake alluvial plains, gentle slopes of lakes, low lake terraces).

Submicron Aerosol and Black Carbon in the Troposphere of Southwestern Siberia (1997–2018)

Based on the multiyear measurements in the surface atmospheric layer (from five stations) and regular flights of aircraft laboratory over the background region of Southwestern Siberia, the compositions of mass concentrations of submicron aerosol and absorbing substances (soot and black carbon) are analyzed. The annual average concentrations of submicron aerosol and black carbon were found to be maximal in 1997, 2012, and 2016, when the largest numbers of wildfires occurred across the entire territory of Siberia. No significant, unidirectional trend of interannual variations in the concentration of submicron particles was observed, while the concentration of absorbing substance reliably decreased by 1.5% each year. To estimate the effect of urban pollutants, mass concentrations of aerosol and absorbing substance in the surface layer at the Aerosol Station (in the suburban region of Tomsk) were compared to those at the Fonovaya Observatory (in the background region). It was shown that the largest contribution of anthropogenic sources in the suburban region was observed in the winter season, while minimal difference was observed in the warm period of the year. The seasonal behavior of the concentrations of elemental carbon at three stations in Novosibirsk Oblast almost completely matched the dynamics of the variations in the black carbon concentration in the atmosphere of Tomsk Oblast. Data of aircraft sensing in the troposphere of the background region of Southwestern Siberia (2000–2018) were used to determine the average values of the vertical distribution of the submicron aerosol and black carbon concentrations in the altitude range of 0.5–7 km for each season. It was found that at altitudes of 0.5–7 km, there were no unidirectional trends in submicron aerosol; however, there was an increase of black carbon concentration at all altitudes with a positive trend of 5.3 ± 2.2% per year at an altitude of 1.5 km, significant at a p-value = 0.05.

The Origin and Dispersal of Uralic: Distributional Typological View

Recent progress in comparative linguistics, distributional typology, and linguistic geography allows a unified model of Uralic prehistory to take shape. Proto-Uralic first introduced an eastern grammatical profile to central and western Eurasia, where it has remained quite stable. Proto-Indo-European and Proto-Uralic had no connection, either genealogical or areal, until the spreading Indo-Iranian branch of Indo-European came into contact with the already-diverged branches of Uralic about 4,000 years ago. A severe and widespread drought beginning about 4,200 years ago cleared the way for a rapid spread of Uralic-speaking people along the Volga and across southwestern Siberia. It also contributed to the sudden rise of the Seima-Turbino bronze-trading complex, one component of the Uralic spread mechanism. After the initial spread, the Uralic daughter languages retained their Volga homelands remarkably stably while also extending far to the north in a recurrent Eurasian pattern.

A new species of the genus Lucasioides Kwon, 1993 (Isopoda, Oniscidea, Agnaridae) from Siberia, Russia

A new species of the family Agnaridae, Lucasioides altaicus sp. nov., is described from the Altai Mountains, southwestern Siberia, based both on morphological characters and molecular data. This species is the first record of Lucasioides from Russia, whose location is the northernmost habitat of terrestrial isopods in indigenous habitats presently known to Eurasia. The diagnostic characters of the new species and a preliminary phylogenetic analysis within Agnaridae are provided.
