An early iron age camp of reindeer hunters in the bolshezemelskaya tundra, nenets autonomous okrug
This study outlines the findings of excavations at More-Yu II-a site in the northern Bolshezemelskaya tundra. The habitation-layer, with numerous charcoal lenses, was discovered inside the layer of buried soil, which was overlaid by eolian sand. Most of the finds are ceramics and animal bones; arrowheads, adornments, tools, and ritual items are very rare. On the basis of palynological and faunal analyses, environmental changes from the time of Subboreal warming until the end of the Subatlantic period are reconstructed. The temperature regime during the formation of cultural deposits was unstable. The principal subsistence strategy was reindeer hunting. The age distribution of the hunted reindeer suggests that habitation periods coincided with cold seasons. Radiocarbon dates generatedfrom reindeer bones point to the Early Iron Age. The camp dwellers were native reindeer hunters inhabiting the tundra belt of northeasternmost Europe. Ceramics representing the More-Yu type belong to the early stage of the Subarctic Pechora culture. They mark the Arctic component that became part of the northern Glyadenovo population, abruptly changing the Finno-Permic culture of the taiga part of the Pechora basin in Cis-Urals. © 2019 Siberian Branch of the Russian Academy of Sciences
Phylogeography and population history of the least weasel (Mustela nivalis) in the Palearctic based on multilocus analysis
The least weasel (Mustela nivalis) is one of the most widely distributed carnivorans. While previous studies have identified distinct western and eastern mitochondrial DNA (mtDNA) lineages of the species in the western Palearctic, their broader distributions across the Palearctic have remained unknown. To address the broad-scale phylogeographical structure, we expanded the sampling to populations in Eastern Europe, the Urals, the Russian Far East, and Japan, and analyzed the mtDNA control region and cytochrome b, the final intron of the zinc finger protein on Y chromosome (ZFY), and the autosomal agouti signaling protein gene (ASIP). The mtDNA data analysis exposed the previous western lineage (Clade I) but poorly supported assemblage extending across Palearctic, whereas the previous eastern lineage (Clade II) was reconfirmed and limited in the south western part of the Palearctic. The ZFY phylogeny showed a distinctive split that corresponding to the mtDNA lineage split, although less phylogeographical structure was seen in the ASIP variation. Our data concur with the previous inference of the Black Sea–Caspian Sea area having an ancestral character. The Urals region harbored high mitochondrial diversity, with an estimated coalescent time of around 100,000 years, suggesting this could have been a cryptic refugium. Based on the coalescent-based demographic reconstructions, the expansion of Clade I across the Palearctic was remarkably rapid, while Clade II was relatively stable for a longer time. It seems that Clade II has maintained a constant population size in the temperate region, and the expansive Clade I represents adaptation to the cold regions. © 2019 Blackwell Verlag GmbHJapan Society for the Promotion of Science, JSPSRussian Foundation for Basic Research, RFBRJapan Society for the Promotion of Science, JSPSAAAA‐A17‐117022810195‐3We would like to thank T.

Holocene Changes in the Distributions of Asian and European Badgers (Carnivora: Mustelidae: Meles) Inferred from Ancient DNA Analysis
Although the present-day distributional boundary between the European badger (Meles meles) and the Asian badger (Meles leucurus) is around the Volga River, studies of ancient bone remains have indicated changes in the distribution of M. meles and M. leucurus in the Urals-Volga region during the Holocene. To examine past changes in distribution using genetic data, changes in genetic diversity, and the relationships of Holocene to modern populations, we sequenced ~150 bp of the mitochondrial DNA control region from the 44 ancient badger remains excavated from European Russian, Ural and Western Siberian sites, and we detected 12 haplotypes. Our study revealed Holocene changes in the distributional boundary between these badger species. Meles meles inhabited the Ural Mountains east of the Volga River in the Early Holocene, whereas M. leucurus expanded its distribution westwards, starting ~2500 years ago. Thereafter, M. leucurus rapidly replaced M. meles in the region between the Urals and the Volga, resulting in the present-day boundary in the Volga-Kama region. Among the 12 haplotypes detected, three for M. leucurus and four for M. meles were identical to partial sequences of haplotypes detected in modern populations, indicating considerable genetic continuity between Holocene and modern populations. © 2020 The Linnean Society of London, Biological Journal of the Linnean Society.We thank Dr Irina Kirillova for providing the badger samples from Tver Province; the Museum of the Institute of Plant and Animal Ecology, Ural Branch, Russian Academy of Sciences for providing specimens; and Dr Mathew Dick for invaluable comments and English editing of the manuscript.

INFORMATIVE CAPACITY OF THE SARGAT CULTURE’S DISTURBED BURIALS: KURGAN NOVOPOKROVKA 16 IN THE MIDDLE IRTYSH RIVER BASIN 1
The article deals with a complex study of the materials obtained during archaeological excavation of the kurgan Novopokrovka 16 in the middle Irtysh river basin (Omsk region). The site, which is attributed to the Sargat culture (5th century BC – second half of the 3rd centuryAD), was located farmost on the right bank of the river Irtysh, nearby the group of “Princely kurgans”. Despite almost total disturbance by robbers and agricultural activity, common scholars’ efforts demonstrate high informative capacity of the multidisciplinary approach, while modern level of undertaken research is not just being declared but enables to reconstruct seemingly lost information. The kurgan erection stages and mound structure features have been decoded using the results of a geophysical survey and soil morphology data. The paleoanthropological study of the incomplete skeletal remains does not support multiple or inlet interment inside the central grave, and provides sexing and aging of the buried individuals as well as some paleopathological observations. Apart from species examination, archaeozoological data testify that a warm period from spring to early autumn was the season of animal slaughter. Characteristics of mortuary rituals and direction of intercultural contacts of the ancient forest-steppe groups have been completed by new details based on the results of strontium isotope analyses (dental enamel of humans and animals) and evidence non-local origin of the individual buried under the excavated kurgan, what is different from local origin of horses butchered for funereal feasts. The proposed hypothesis supports previously suggested archaeological, paleoanthropological and paleogenetic facts on the origin of the forest-steppe population, indicating an involvement of various population groups with notable external components. Based on the archaeological materials, the kurgan under study might be dated back to mid-4th – 3rd centuries BC. © 2023 The Author(s).Ministry of Education and Science of the Russian Federation, Minobrnauka: 075-15-2021-680The article was prepared in the framework of the state orders No. 121102500121-8, 123011800012-9, 1021061810416-7, АААА-А19-119013090163-2, RFBR grant No. 21-59-23003.

Species-specific responses of Late Quaternary megafauna to climate and humans
Despite decades of research, the roles of climate and humans in driving the dramatic extinctions of large-bodied mammals during the Late Quaternary remain contentious. We use ancient DNA, species distribution models and the human fossil record to elucidate how climate and humans shaped the demographic history of woolly rhinoceros, woolly mammoth, wild horse, reindeer, bison and musk ox. We show that climate has been a major driver of population change over the past 50,000 years. However, each species responds differently to the effects of climatic shifts, habitat redistribution and human encroachment. Although climate change alone can explain the extinction of some species, such as Eurasian musk ox and woolly rhinoceros, a combination of climatic and anthropogenic effects appears to be responsible for the extinction of others, including Eurasian steppe bison and wild horse. We find no genetic signature or any distinctive range dynamics distinguishing extinct from surviving species, underscoring the challenges associated with predicting future responses of extant mammals to climate and human-mediated habitat change.This paper is in the memory of our friend and colleague Dr. Andrei Sher, who was a major contributor of this study.

Winter Temperature and Forest Cover Have Shaped Red Deer Distribution in Europe and the Ural Mountains Since the Late Pleistocene
Aim: The Expansion-Contraction model has been used to explain the responses of species to climatic changes. During periods of unfavourable climatic conditions, species retreat to refugia from where they may later expand. This paper focuses on the palaeoecology of red deer over the past 54 ka across Europe and the Urals, to reveal patterns of change in their range and explore the role of environmental conditions in determining their distribution. Location: Europe and western Asia to 63°E. Taxon: Red deer (Cervus elaphus). Methods: We collected 984 records of radiocarbon-dated red deer subfossils from the Late Pleistocene and the Holocene, including 93 original dates. For each deer sample we compiled climatic and biome type data for the corresponding time intervals. Results: During the last 54 ka changes in red deer range in Europe and the Urals were asynchronous and differed between western and eastern Europe and western Asia due to different environmental conditions in those regions. The range of suitable areas for deer during the Last Glacial Maximum (LGM) was larger than previously thought and covered vast regions not only in southern but also in western and eastern Europe. Throughout the period investigated the majority of specimens inhabited forests in the temperate climatic zone. The contribution of forests in deer localities significantly decreased during the last 4 ka, due to deforestation of Europe caused by humans. Mean January temperature was the main limiting factor for species distribution. Over 90% of the samples were found in areas where mean January temperature was above −10°C. Main conclusions: Red deer response to climatic oscillations are in agreement with the Expansion-Contraction model but in contradiction to the statement of only the southernmost LGM refugia of the species. During the last 54 ka red deer occurred mostly in forests of the temperate climatic zone. © 2020 John Wiley & Sons Ltd.European Social Fund, Grant/Award Number: UDA-POKL.04.01.01-00-072/09-00; University of Wroclaw, Grant/Award Number: 0410/2990/18; Institute of Environmental Biology, University of Wrocław, Grant/Award Number: 0410/2990/18; Mammal Research Institute Polish Academy of Sciences; Narodowe Centrum Nauki , Grant/Award Number: DEC-2013/11/B/NZ8/00888 and UMO-2016/23/B/HS3/00387; Romanian National Authority for Scientific Research, UEFISCDI, Grant/Award Number: PN-IIIP4-ID-PCE-2016-0676; National Centre for Atmospheric Science and the Centre for Environmental Data Analysis, UK; Faunal Database of the Stage Three Project; Leverhulme Trust, Grant/Award Number: F00568W
