Introduction. In 2008 and 2015, two settlements of the Khazar era — referred to as Bashanta-I and Bashanta-II by the name of the locality respectively — were discovered. The joint archaeological expedition of Kalmyk Scientific Center (Russian Academy of Sciences) and Khalikov Institute of Archaeology (Tatarstan Academy of Sciences) headed by Dr. M. Ochir-Goryaeva is systematically exploring the monuments. The comprehensive research efforts involve the use of GIS methods. Analysis of animal bones resulted in five radiocarbon dates that may attest to that Bashanta-I and Bashanta-II are the earliest available sites of the Khazar domain. Further analysis of archaeological materials — Black Sea amphorae — confirms the mentioned radiocarbon-based conclusion. Goals. The paper seeks to review the newly discovered monuments comparing them to each other and other hillforts of the Khazar Khaganate. There have been a few excavation seasons only, and the observations are essentially preliminary. Results. In both the sites, large areas of cultural layers were opened. In Bashanta-I, this revealed remains of a stone building and a 189 meter long wall base composed of massive shell limestone blocks. The wall delineates the outer border of the once inhabited area. The eastern hill of Bashanta-II contains a similar fragmented wall base that served to separate the central part from the rest of the settlement. The wall encircled a number of round half dugout clay-and-wattle buildings and multiple middens. In Bashanta-II, the cultural layer contains (along with amphorae) numerous Saltovo-Mayaki pottery fragments and no traces of roof tiles. While ceramics of Bashanta-I is represented exclusively by amphorae fragments, and no samples of pottery or molded ceramics have been discovered. However, many fragments of roof tiles are observed along the wall base and the building area of Bashanta-I. It is noteworthy that all the roof tiles were brought in from offsite, and are distinguished by high quality, while other Khazar hillforts contain only scarce samples of locally-made tiles. Conclusion. According to G. Afanasiev’s typology, the obtained data make it possible to classify Bashanta-I as a fortress, and Bashanta-II as a fortified settlement.

There are two caves containing groups of wall paintings of the Upper Paleolithic age known in the Southern Ural: Kapova (Shulgan-Tash) and Ignatievskaya (Yamazy-Tash). In total, about 200 pictorial motifs have been recorded in the Kapova cave, among which there are life-like depictions of Pleistocene animals (mammoth and rhinoceros). Some 180 pictorial motifs have been found in the Ignatievskaya cave, which also show images of the Pleistocene fauna (mammoth and rhinoceros), although less realistic than those in the Kapova cave. The cultural layers have been discovered in the cave sediments at both sites. Archaeological excavations in the Kapova cave revealed multiple cultural layers which contained remains of the hearths, stone artefacts, fragments of ochre, decorations made of stone and tusk, a piece of burnеd clay cup, bone tools and animal bones (some with traces of ochre paint). In the Ignatievskaya cave, the Paleolithic cultural layer contains numerous fragments of charcoal, stone artefacts, rare fragments of ochre, decorations made from teeth of arctic fox and bison and from mammoth tusk, as well as the bones of Pleistocene animals. In the past two decades, a series of radiocarbon dates has been reported by different researchers based on the charcoal and bones from the cultural layers in both caves. Seventeen dates have been reported for the Kapova cave, including 14 Upper Paleolithic, 2 Bronze Age and 1 modern dates. The materials from the cultural layer of the Ignatievskaya cave have yielded 6 radiocarbon dates; another 3 dates were obtained directly from the charcoal used for the black paintings in the cave. Our analysis of publications, in which the radiocarbon dates from the Upper Paleolithic cultural layers of the Kapova and Ignati-evskaya caves are used, has revealed that the dating results are often reported inaccurately or incompletely, which leads to serious errors in interpretations. In particular, the incorrect use of non-calibrated radiocarbon dates as calendar ages, completely changes the paleoclimatic context of the cave occupation; for the Kapova cave, for instance, such misinterpretation shifts the dates of the cave visiting and painting from the late part of the Last Glacial Maximum and early deglaciation to the Bølling-Allerød interstadial. In this paper, we revisit the published radiocarbon ages for these two Southern Ural sites, provide practical recommendations and re-emphasize the importance for accurate and complete reporting of radiocarbon ages in publications.

The processes of Neolithization and Eneolithization are two of the most important in the study of the human prehistory. The territory of the Lower Volga is of particular importance. In the Neolithic period, one of the oldest ceramic traditions in Eastern Europe appears. In the Eneolithic, cultures with signs of a productive economy are recorded rather early here. A further study of these issues depends on a quality source base. Monuments of the Neolithic and Eneolithic in the Volga steppe are rare. Therefore, the study of the new site Algay is very relevant. Its importance increases due to the discovery of stratigraphic data in 2019: the Eneolithic and Neolithic layers are separated by relatively sterile layers. This allows us to establish reliable periodization. Features of the lower cultural layer allowed us to trace the process of its formation. The work was interdisciplinary. The results of the technical and technological analysis of ceramics revealed the characteristic features of the Neolithic and Eneolithic. Archaeozoological definitions established the species composition of animals in the Neolithic and Eneolithic. New radiocarbon dates provide a basis for determining the exact chronological framework of the Orlovskaya and Caspian cultures in this region. Among archaeological materials, rare artifacts have been discovered that testify to social stratification already in the Neolithic period.

Interdisciplinary Study

В статье рассматриваются результаты междисциплинарного исследования малоизвестного в настоящее время археологического памятника Долгое 11. Приводятся детальное литологическое описание разреза, подробные характеристики строения палеопочв, положения четко различимых двух культурных слоев. Археологические материалы из верхнего и нижнего культурных слоев сильно отличаются друг от друга как по сырью, из которого они изготовлены, так и по типологическим и технологическим характеристикам. Абсолютная хронология полученная методом ОСЛ позволила определить возраст нижнего культурного горизонта -около 13,5-14 тыс. л. н. Расселение древних людей в районе стоянки происходило в условиях потепления аллереда, поэтому этот культурный слой коррелируется с палеолитом. Верхний культурный горизонт сформировался уже в голоцене - в эпоху мезолита (около 9 тыс. л. н.), как показало исследование, рельеф стабилизировался в это время из-за повсеместного развития растительности. The article discusses the results of the interdisciplinary study of the presently little-known Dolgoe 11 archaeological site. The materials of the lithological description of the section, detailed characteristics of the structure of paleosols, the positions of clearly distinguished two cultural layers are given. Archaeological materials from the upper and lower cultural layers are very different from each other, both in the raw materials used for their shaping, and in typological and technological characteristics. The absolute chronology from OSL dating allows determine the age of the lower cultural horizon about 13,5-14 thousand years ago. The settlement of humans in the area of the site occurred under the conditions of Allerod warming, therefore, this cultural layer is correlated with Paleolithic. The upper cultural horizon was formed already in the Holocene -in the Mesolithic era (about 9 thousand years ago). during relief stabilisation due to the widespread development of vegetation.

The article presents new radiocarbon dates obtained on the materials of the Volgo-Kamskaya and Kamskaya Neolithic cultures in the Kama River basin. In the paper, the data of original material for dating and methods were considered. Eleven new radiocarbon dates from eight Neolithic sites of region were obtained. The sites are located on the territory of the Upper Kama River basin (4 archaeological sites), the Kama-Vyatka basin (2 archaeological sites), and the Lower Kama River basin (2 archaeological sites). The main material for radiocarbon dating was the organics from pottery. Together with radiocarbon dates on organics from pottery, the dates on charcoal and animal bones were obtained. The dates on different organic materials have a good correlation. These results are new data for the early and developed stages of the Kamskaya culture. The earliest dates were obtained for unornamented pottery of the Volga-Kamskaya culture. This can be an evidence of priority of this culture in respect of pottery production in the Kamariver basin. This suggestion is confirmed by archaeological materials from neighbour regions. On other hand, the results of radiocarbon dating allow authors to conclude about synchronic existence of ceramic traditions with pinned and combed ornamentation from the middle of 6th to the middle of 5th millennium BC in region under consideration. However, the sites with pinned ornamented pottery appeared in the region earlier than the sites with ceramics ornamented by comb. The investigations gave the possibility to determine the time of appearance of sites with collarlike corolla pottery and pit-combed ornamented pottery in the Kama river region. The appearance of this type of ceramics in the region testifies to the contacts of the Kamskaya Neolithic culture community with people from the southern and eastern regions.

Intermittent Lighting Improves the Efficiency of Artificial Insemination in Cage Housed Laying Hens Kavtarashvili A.Sh., Kolokolnikova T.N. Federal Scientific Center “All-Russian Research and Technological Poultry Institute” of Russian Academy of Sciences Omsk Agrarian Scientific Center Summary: The effects of different lighting regimes on the oviposition schedule, productive performance, and reproductive efficiency in cage housed laying hens of layer parental flock (Hisex White-R) were studied; the reasonable regime of artificial insemination (AI) under intermittent lighting is proposed. It was found that intermittent lighting regime 1L:4D:4L:1D:4L:10D compared to the constant lighting significantly alters oviposition schedule: under this regime 82.3% of all daily eggs were laid until 9 am (vs. 66.6% in control). This regime and AI at 10 am improved the productive and reproductive performance compared to control (constant lighting 16L:8D and AI at 12 am): mortality by 1.9%, egg production per initial hen by 3.8%, egg weight by 1.1%, percentage of eggs suitable for incubation by 1.9%, egg fertility by 0.9%, hatchability by 2.3%, hatch of chicks by 2.9%, feed conversion ratio (kg of feed per 10 eggs) by 5.3%, the expenses of electric energy for lighting (per 1000 eggs suitable for incubation) by 54.5%.

The article studies the possibility to use glycerol as cryoprotectant, instead of dimethylsulfoxide for cryopreservation of sperm of inconnu ( Stenodus leucichthys Gueldenstaedtii, 1772). Investigations were carried out from 2015 to 2016 in the laboratory of the Southern Scientific Center, Russian Academy of Sciences, on the basis of the Astrakhan State Technical University. The material collected on the Alexander sturgeon hatcheries (the Astrakhan region) in the spawning period. Native sperm of 6 male inconnu species was used as a control means. The semen quality was determined in terms of moving activity (life time) of sperm after its activation by water. As the cryoprotectant there were used: base solution - 80%, sucrose - 1.71 g/l, mannite - 0.98 g/l, yolk - 10%, dimethylsulfoxide - 10% and base solution - 87%, sucrose - 1.71% g/l, mannite - 0.98 g/l, yolk - 10%, glycerol - 3 variants: 3; 5 and 10%. In order to provide the most complete penetration of cryoprotectants into the cells there were used electrostimulation of cell membranes. Equilibration time was 5 and 15 minutes. Thawing semen was performed in a water bath at a temperature of 38-40°C. For removing protectors from cells there was chosen a saline solution (0.7% NaCl) as isotonic solution. In tests using dimethylsulfoxide life activity of sex cells was 2 times lower than in tests with glycerol: 78 and 186.2 s at the end of equilibration and 52.3 and 128.9 s after thawing. Sperm showed maximum activity under 5% glycerol concentration during equilibration - 15 min. Concentration of 3% was insufficient, concentration of 10% was excessive, as it suppressed activity of sperm. Egg yolk which coagulated together with glycerol, making difficulty for observing, had to be excluded from the composition of cryoprotectant.

Показана актуальность изучения экологической пластичности древесных растений в связи с необходимостью подбора адаптированного видового состава деревьев и кустарников для защитных лесных насаждений в условиях климатических изменений. Установлено, что экологическая пластичность и пределы толерантности растений связаны со свойством организмов адаптироваться к тому или иному диапазону факторов среды. В статье представлен таксономический состав орехоплодных культур коллекций ФНЦ агроэкологии РАН. Это шесть видов рода Juglans: J. regia, J. mandshurica, J. cinerea, J. rupestris, J. ailanthifolia, J. nigra и три вида рода Corylus: С. avellana L., С. аmericana W., сорта С. pontica C. Koch Президент, Футкурами, Черкесский2. Приведены сведения о положительном опыте культивирования Corylus avellana L. в плантационных насаждениях (1,6 га, посадка рядовая, схема размещения 55 м) в условиях южных черноземов. Цель исследований изучить экологическую пластичность орехоплодных кустарников коллекций ФНЦ агроэкологии РАН. На примере родового комплекса Corylus получены материалы по экологической пластичности орехоплодных кустарников в условиях каштановых (кадастр. 34:36:0000:14:0178), светлокаштановых почв (34:34:000000:122 34:34:060061:10). Установлены уровни изменчивости морфологических признаков ассимиляционного аппарата и плодов С. avellana L., сортов С. pontica C. Koch., которые согласуются с зимо и засухоустойчивостью. Кластерный анализ позволил выявить корреляцию признаков при 5 уровне значимости. Для целей защитного лесоразведения и озеленения засушливых районов рекомендованы Corylus avellana и Черкесский2 с выраженной вариабельностью морфологических признаков, которая указывает на их широкую экологическую валентность и адаптационные возможности в рассматриваемых условиях. The urgency of studying the ecological plasticity of woody plants in connection with the need to select an adapted species composition of trees and shrubs for protective forest plantations in the context of climate change is shown. It is established that the ecological plasticity and tolerance range of plants is associated with the ability of organisms to adapt to a particular range of environmental factors. The article presents the taxonomic composition of nut crops in the collections of FSC Agroecology RAS. Six species of Juglans: J. regia, J. mandshurica, J. cinerea, J. rupestris, J. ailanthifolia, J. nigra and three species of the genus Corylus: С. avellana L., С. аmericana W., varieties of C. pontica C. Koch the President, Futkurami, Circassian2. Data on positive experience of cultivation of Corylus avellana L. in plantation plantings (1,6 hectares, landing ordinary, the scheme of placement of 55 m) in the conditions of southern chernozems are given. The purpose of the research is to study the ecological plasticity of nutbearing shrubs of the collections of the Federal scientific center for Agroecology Russian Academy of Sciences. For example, a generic complex Corylus submissions received on the environmental plasticity of nut bushes in the conditions of brown (the cadaster nubmer 34:36:0000:14:0178), light chestnut soils (34:34:000000:122 34:34:060061:10). The levels of variability of morphological features of the assimilation apparatus and fruits of Corylus avellana L., С. pontica C. Koch varieties were established., which are consistent with winter and drought resistance. Cluster analysis revealed the correlation of features at 5 significance level. Corylus avellana and Circassian2 with a pronounced variability of morphological features, which indicates their broad ecological valence and adaptation capabilities in the conditions under consideration, are recommended for the purposes of protective afforestation and greening of dry areas.

The application of biomolecular techniques to archaeological materials from the Balkans is providing valuable new information on the prehistory of the region. This is especially relevant for the study of the neolithisation process in SE Europe, which gradually affected the rest of the continent. Here, to answer questions regarding diet and subsistence practices in early farming societies, we combine organic residue analyses of archaeological pottery, taxonomic and isotopic study of domestic animal remains and biomolecular analyses of human dental calculus. The results from the analyses of the lipid residues from pottery suggest that milk was processed in ceramic vessels. Dairy products were shown to be part of the subsistence strategies of the earliest Neolithic communities in the region but were of varying importance in different areas of the Balkan. On the other hand, we did not confidently detect any milk proteins within the dental calculus. The molecular and isotopic identification of meat, dairy, plants and beeswax in the pottery lipids also provided insights into the diversity of diet in these early Neolithic communities. We also present the first compound-specific radiocarbon dates for the region, obtained directly on absorbed organic residues extracted from pottery, identified as dairy lipids.
