Against the intensive studies of the genetic composition of early nomads from the Altai-Sayan mountain system, a number of Scythian populations from the adjacent forest-steppe zone remain unexplored by paleogenetic methods. This article presents the first results of a paleogenetic study of the Staroaleisk culture carriers from the Firsovo-XIV burial ground in the Barnaul Ob region. Analysis of a small series of mitochondrial DNA samples (N = 10) confirmed the participation of populations associated with the autochthonous genetic substrate of the southern regions of Western Siberia in the formation of the genetic composition of the Staroaleisk population (specific composition of the Western Eurasian component of the mtDNA gene pool and the presence of autochthonous Eastern Eurasian A10 haplogroup). We showed the presence of mtDNA (lineages of haplogroups A8 and A11) in the Staroaleisk population, which testifies to its genetic ties with the carriers of the Scythian-Siberian cultures who inhabited the territories to the east of the Upper Ob region – the Altai- Sayan mountain system, Tuva and adjacent regions of Central Asia. Thus, paleogenetic data indicate that the genetic composition of the Sratoaleisk population was formed under the conditions of the genetic interaction between autochthonous populations of the region, whose genetic roots go back to the Bronze Age, and newly migrated groups who were carriers of the cultural traditions of the Scythian-time nomads. Taking into account the informative value of the first genetic results, we can expect a significant detailing of ethnogenetic processes reconstructions with increasing of DNA samples from the Staroaleisk population, analysis of additional genetic markers (Y-chromosome) and obtaining data on the gene pool of other early Iron Age populations from the Upper Ob region and adjacent regions of the South Siberia.

The monograph presents an overview of the forest-steppe vegetation of the West Siberian Plain and the Altai-Sayan mountain region. The questions of bioclimatic zonation of the Altai-Sayan mountain region are discussed. The biodiversity of foreststeppe is characterized, the floristic classification is performed, the scheme of eco-phytocoenotic classification is given, the basic types of plant communities are described in comparative terms. The diversity of forest-steppe landscapes is revealed, the structure of their vegetation is analyzed. The phytogeographical division of forest-steppe is worked out.

Improvement of dendrochronological crops yield reconstruction by separate application of earlywood and latewood width chronologies succeeded in rain-fed semiarid region. (1) Background: Tree-ring width chronologies have been successfully applied for crops yield reconstruction models. We propose application of separated earlywood and latewood width chronologies as possible predictors improving the fitness of reconstruction models. (2) Methods: The generalized yield series of main crops (spring wheat, spring barley, oats) were investigated in rain-fed and irrigated areas in semiarid steppes of South Siberia. Chronologies of earlywood, latewood, and total ring width of Siberian larch (Larix sibirica Ledeb.) growing in forest-steppe in the middle of the study area were tested as predictors of yield reconstruction models. (3) Results: In the rain-fed territory, separation of earlywood and latewood allowed increasing variation of yield explained by reconstruction model from 17.4 to 20.5%, whereas total climatic-driven component of variation was 41.5%. However, both tree-ring based models explained only 7.7% of yield variation in the irrigated territory (climate inclusion increased it to 34.8%). Low temperature sensitivity of larch growth was the main limitation of the model. A 240-year (1780–2019) history of crop failures and yield variation dynamics were estimated from the actual data and the best reconstruction model. (4) Conclusions: Presently in the study region, breeding of the environment-resistant crops varieties compensates the increase of temperature in the yield dynamics, preventing severe harvest losses. Tree-ring based reconstructions may help to understand and forecast response of the crops to the climatic variability, and also the probability of crop failures, particularly in the rain-fed territories.

ABSTRACTExcavations at several locations in Verteba Cave have uncovered a large amount of human skeletal remains in association with faunal bones and Tripolye material culture. We aim to establish radiocarbon (14C) dates for eight sites and to evaluate whether these deposits are singular events, or slow accumulations over time.14C measurements, along with stable carbon and nitrogen isotope data from human and faunal remains, were collected from 18 specimens. Stable isotope values were used to evaluate human and animal diet, and whether freshwater reservoir effects offset measured dates. We found diets of the sampled species had limited to no influence from freshwater resources. Human diet appears to be dominated by terrestrial plants and herbivores. Four new sites were identified as Eneolithic. Comparisons of dates from top and bottom strata for two sites (7 and 20) reveal coeval dates, and we suggest that these deposits represent discrete events rather than slow continuous use. Lastly, we identified dates from the Mesolithic (8490±45 BP, 8765±30 BP), Iron Age (2505±20 BP), Slavic state era (1315±25 BP), and Medieval Period (585±15 BP), demonstrating periodic use of the cave by humans prior to and after the Eneolithic.

Motroninsky ancient settlement belongs to the most famous monuments of the Scythian epoch of the Dnieper Forest-Steppe Right Bank. Since the late 1980s and until today, work is underway to study the monuments of this time in the vicinity of the site of the ancient settlement. This work is based on materials that identify the chronological and periodic frames of the surveyed monuments. In total 21 settlements of Scythian time of VII—III centuries BC were surveyed and opened. The results of this work confirm the version of the researchers of the site of ancient settlement that its main population lived outside the fortification in a radius of several kilometers.

With 26 named species (Platnick 2011), Acantholycosa Dahl, 1908 is a relatively large Holarctic genus in the wolf spider subfamily Pardosinae Simon, 1898. Acantholycosa was recently revised and 17 species were described as new to science (Marusik et al. 2004). The majority of species occur in Northern Asia and the highest species diversity is known from the Altai-Sayan Mountain System (18 species) (Marusik et al., 2004). Among the newly described species was Acantholycosa logunovi Marusik, Azarkina & Koponen, 2004 from Altai in Russia. The female epigyne of this species was found to be remarkably similar to those of A. norvegica (Thorell, 1872), while male palp was similar to those in A. plumalis species group. While collecting spiders in Altai the senior author collected over a dozen specimens belonging to Acantholycosa of which one pair was in copula. Study of this material revealed that males were conspecific with figures of the holotype of A. logunovi, but that females were different from those illustrated by Marusik et al. (2004). The females described as A. logunovi by Marusik et al. (2004) are instead A. norvegica and therefore females of A. logunovi remained undescribed up until now. Here we describe the female of A. logunovi, provide comparisons with related species and add to the known localities of this species.
