Geochronology of vegetation stages of south-east Baltic coast (Kaliningrad region) during the middle and Late Holocene

The raised bog sediments that have been continuously accumulated over time represent the most suitable natural object which enables us to reconstruct Late Glacial and Holocene vegetation and palaeoclimates. Bog peat consists of organic carbon formed in situ. It contains moss, plant fragments and microfossils that are necessary for the study of palaeovegetation and palaeoclimate. However, a successful study of palaeoenvironment can be carried out on the basis of investigation of a great quantity of samples along the whole peatbog thickness. In the present paper, the authors present the results of palynological, botanical investigations and radiocarbon dating of 31 peat samples taken from the raised bog Velikoye, located in the eastern part of Kaliningrad Region. The data obtained have enabled us to reconstruct the palaeovegetation, reveal the evolution of the bog and determine rate of peat formation at different evolutional stages over the last 7500 cal BP.     

Hunter–gatherer migrations,mobility and social relations: A case study from the Early Bronze Age Baikal region,Siberia

A large data set of geochemical data (⁸⁷Sr/⁸⁶Sr, ¹⁴C, δ¹³C, and δ¹⁵N) was obtained for a middle Holocene Early Bronze Age Khuzhir-Nuge XIV cemetery (∼4650–3950 cal. BP) in the Baikal region of Siberia. This material is analyzed at the individual level and in the context of demographic data and spatial arrangements within the cemetery revealing a number of new insights about hunter–gatherer adaptive strategies in the region. During the Early Bronze Age, the Little Sea area of the Baikal region witnessed entire hunter–gatherer families migrating there from other parts of the Cis-Baikal, such as the Angara and upper Lena valleys. While all larger spatial units discernible at Khuzhir-Nuge XIV, such as the East, Centre, and West Sectors, scattered graves, and rows of graves, included individuals of local and non-local birth, it is evident that the area of origin was an important cultural variable well marked in the various smaller spatial arrangements such as the rows, sub-sectors, and groups of graves. The two different diets identified among the analyzed group of people (Game-Fish-Seal and Game-Fish) show interesting spatial distribution patterns. While both diets are present in the East and Centre Sectors, the West Sector is composed only of individuals characterized by the GFS diet. All locals subsisted on the GFS diet, while the non-locals featured a mix of individuals with either GFS or GF diet. It appears that status was not linked to the area of origin, for individuals of both local (GFS) and non-local diet (GF) were buried within the “rich” East Sector, however, in spatially separate arrangements suggesting further that the area of origin was an important social distinction among these high status individuals. The similarity in diet catchment patterns and diets for individuals interred in the same graves and row, and the differences between some rows, suggest existence of distinct foraging ranges used by separate social units, such as families.     

Micro-sampling of human bones for mobility studies: diagenetic impacts and potentials for elemental and isotopic research

The nature of long bone formation and the pathways of interaction between bone samples and the burial environment suggest that portions of the bones disconnected from the arterial system are resistant to diagenetic alteration. Preliminary work on femurs from Early Bronze Age hunter-gatherers in Cis-Baikal, Siberia shows that the nature and progression of chemical changes in the bone matrix due to microbial attack can be analyzed using laser ablation inductively coupled plasma mass spectrometry. Intra-osteon variability in elemental concentrations and strontium isotope ratios (⁸⁷Sr/⁸⁶Sr) indicate the presence of unaltered portions of bone within diagenetically modified bone and suggest that useful data remain accessible. These biogenic signals can potentially be useful for mobility research in broad terms and the smaller timescales within an individual's lifetime (months, years), accessible therein. Laser ablation micro-sampling of femur specimens showed that intra-osteon elemental composition of Ba, Re, and Cs varied within and was correlated between multiple osteons of a single bone. Portions of chemically unaffected bone were identified within, and effectively discriminated from diagenetically altered bone tissue. Areas showing visual alterations and erratic or uncorrelated Ca and Sr elemental results also had anomalous Sr isotope ratios, suggesting diagenetic alteration in those places. Compositional and isotopic analysis of intact portions of bone supports the hypothesis that hunter-gatherer groups in Cis-Baikal made numerous major movements during their lives. Microscopic analysis of long bones clarifies aspects of biodeterioration and correlations between trace elemental results and diagenetic alteration. Micro-sampling of intact portions of bone expands the scope of available materials for research on mobility and other aspects of human past behavior.     

Prehistoric dietary adaptations among hunter-fisher-gatherers from the Little Sea of Lake Baikal,Siberia, Russian Federation

Dietary adaptations of prehistoric hunter-gatherers from Neolithic and Early Bronze Age cemeteries in the Little Sea region of Cis-Baikal (the region to the west and north of Lake Baikal) are explored using stable isotopes of carbon and nitrogen. Stable isotope data, including stable carbon isotopes from bone carbonate, are presented for 22 individuals from the site of Kurma XI, dated to approximately 6500 B.P. to 4000 B.P. Data are compared to previously analyzed individuals from the larger Early Bronze Age cemetery, Khuzhir-Nuge XIV (Katzenberg et al., 2009 JAS) and to smaller sites located along the shore of the Little Sea, including sites on Olkhon Island. An extensive collection of fauna, both prehistoric and modern, from the Little Sea and neighboring regions is also analyzed for stable isotopes of carbon and nitrogen. Clear distinctions are found in modern fish recovered from the Little Sea, in contrast to those from the open waters of the lake and from the neighboring Angara and Lena rivers. Considerable variation is seen in stable carbon isotope ratios from fish while stable nitrogen isotope ratios are not as variable, regardless of habitat. Isotope source modeling is used to assist in reconstructing past dietary adaptations. While there is ample evidence from other studies for cultural change over this temporal span, diet appears to have been relatively stable.     

Discontinuing Traditions: Using Historically Informed Ethnoarchaeology in the Study of Evros Ceramics

Ethnoarchaeological studies of pottery primarily focus on the ethnographic present, often disregarding the role of history in the production of material culture. This paper integrates information from historical sources and ethnographic interviews to better understand stylistic ceramic change. Beginning in the 1920s, undecorated pots largely replaced decorated pottery in the region of Evros, Greece. I argue that historically informed ethnoarchaeology provides the key to documenting and understanding the concomitant changes in the social context of pottery production and consumption and the distribution of material culture.     

The origin of the ancient Egyptian drink Shedeh revealed using LC/MS/MS

Ancient Egyptians were buried with the most precious food and drink as sustenance for their afterlife. One of these was Shedeh, the most valued and appreciated beverage in ancient Egypt. The botanic origin of Shedeh remains unclear as no mention of its raw material has survived. Some scholars have proposed that Shedeh was a pomegranate wine, while others, a grape wine. Presented here is the first ever analytical evidence of Shedeh's origin through the analysis of a sample of a residue from an extraordinarily well preserved Shedeh amphora from King Tutankhamun's collection. The previously developed LC/MS/MS wine markers method for archaeological samples was used and our results reveal Shedeh had a red grape origin.     

Human taphonomy at Khuzhir-Nuge XIV,Siberia: a new method for documenting skeletal condition

This paper employs a new three-part method for documenting skeletal condition in order to examine human taphonomy at the Glaskovo (5000–3700 BP, calibrated) cemetery of Khuzhir-Nuge XIV, located in the Lake Baikal region of Siberia (Russia). Relationships among three distinct aspects of condition – completeness, fragmentation, and articulation – and 15 identified taphonomic factors are investigated in order to explain the high variability observed at the site. Intrinsic skeletal characteristics such as element type and age at death were found to be responsible for some of the variable condition, but cultural activities, particularly mortuary practices, appear to have played even greater roles – both direct and indirect. Articulation, in particular, appears to have been an aspect of skeletal condition which was directly affected by a number of cultural practices. In addition to applying a new method of documenting skeletal condition to human taphonomic analyses, this research explains much of the variable condition observed at Khuzhir-Nuge XIV and emphasizes the significance of cultural practices as taphonomic agents affecting human remains.     

Sustainability of the tourist supply chain and governance in an insular biosphere reserve destination: the perspective of tourist accommodation

ABSTRACT

Small islands in peripheral regions are currently perceived as attractive tourist destinations. Governance plays an important role as a strategy for the revival of such destinations to achieve a more productive, environmental, social and sustainable management structure. ‘Good’ governance of a destination depends on all the actors involved in the tourism network. Such governance requires a redefinition of relations between government and society and minimal boundaries between public and private sectors. This paper has analysed the level of implementation of corporate social responsibility (CSR) in a tourist destination that is a biosphere reserve (BR), the island of Fuerteventura (Canary Islands, Spain), from a comprehensive approach involving a tourism supply chain (TSC) with private and public agents. The focal firms analysed within the TSC have been tourist accommodation establishments in Fuerteventura. The paper shows that the level of involvement of tourist accommodation in CSR is positive. However, this involvement is not sufficiently high to meet the requirements of a destination designated as a BR. Therefore, coordination policies should be developed that promote governance systems and further enhance sustainability in the destination.
