- Aim: The majority of the non-volant mammals now present on the island of Gotland, Sweden, have been introduced in modern times. One exception is the mountain hare (Lepus timidus), which was present on the island more than 9000 years ago. This paper investigates the origins of the Gotland hares and temporal changes in their genetic structure, and considers how they may have reached the island.Location: The island of Gotland, Sweden (57°30′ N, 18°20′ E).Methods: Two fragments of the mitochondrial D-loop 130 + 164 base pairs in length from skeletal remains from 40 ancient mountain hares from Gotland, 38 from the Swedish mainland and five from Lithuania were analysed and compared with 90 modern L. timidus haplotypes from different locations in Eurasia and five haplotypes of the Don-hare (Lepus tanaiticus) morphotype.Results: The Mesolithic hares from Gotland (7304 bc–5989 bc) cluster with modern hares from Russia, Scotland, the Alps and Fennoscandia whereas the Gotland hares from the Neolithic and onwards (2848 bc–1641 ad) cluster with Neolithic hares from the Swedish mainland and modern hares from Fennoscandia. The Neolithic haplotypes from Lithuania and the Don-hare haplotypes were dispersed within the network. The level of differentiation (FST) between the Mesolithic and Neolithic hares on Gotland was twice as great as that observed on the mainland.Main conclusions: The ancient hares on Gotland fall into two haplogroups separated in time, indicating that the mountain hare became extinct at one point, with subsequent re-colonization events. In view of the isolated location of Gotland, it is probable that the hares were brought there by human means of transport.

Prehistoric human impact on wild mammalian populations in Scandinavia
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis aims to study the interactions of pre-agricultural societies in Scandinavia with wild mammals, for example in terms of hunting and translocation. More specifically, the aim is to investigate the possibility of identifying examples of overexploitation, targeted hunting or translocation of wild mammals in prehistoric Scandinavia, and to discuss the implications this could have had for both the wild animals and the humans. The thesis also studies translocation to evaluate the feasibility of using it as a proxy for prehistoric human mobility, and to understand the motivation for this action. Although the focus is on the animals in this thesis, the ultimate purpose is to study humans and their interactions with animals in prehistory. The thesis applies genetic analyses to zooarchaeological material of various mammalian species from different Scandinavian sites, in order to study whether the genetic structures have changed in these species over time, and to assess whether these changes were induced by different human actions. The species studied in this thesis were selected on the basis of the importance they are considered to have had for prehistoric people.The dissertation comprises five studies. The first study investigates the occurrence of mountain hares on the island of Gotland, and discusses how they got there and where they came from. The second study explores the temporal genetic structure of the grey seal in the Baltic Sea, and discusses whether humans and/or climate were the drivers for the sudden disappearance of grey seals from the island of Stora Karlsö. The third study concerns a shift where moose apparently became less important as prey in northern Sweden at the end of the Neolithic period, and discusses whether humans targeted female moose in hunting. The fourth study analyses and discusses the history of the harp seal in the Baltic Sea. The fifth study is a methodological paper which involves identifying seals according to sex, using the dog genome.The overall result of the different case studies shows that there were major population fluctuations over time in all the species studied, and that in some cases, humans are likely to have contributed to this, e.g. through overhunting and translocation. The study also shows that the population fluctuations often occurred in connection with certain climatic events, though it was not possible to separate climatic effects from human impact in terms of the cause.

Tidskriftsartikel (refereegranskat)abstract
- The grey seal (Halichoerus grypus) has been part of the Baltic Sea fauna for more than 9000 years and has ever since been subjected to extensive human hunting, particularly during the early phases of its presence in the Baltic Sea, but also in the early 20th century. In order to study their temporal genetic structure and to investigate whether there has been a genetically continuous grey seal population in the Baltic, we generated mitochondrial control region data from skeletal remains from ancient grey seals from the archaeological sites Stora Förvar (Sweden) and Neustadt (Germany) and compared these with modern grey seal data. We found that the majority of the Mesolithic grey seals represent haplotypes that is not found in contemporary grey seals, indicating that the Baltic Sea population went extinct, likely due to human overexploitation and environmental change. We hypothesize that grey seals recolonised the Baltic Sea from the North Sea. during the Bronze Age or Iron Age, and that the contemporary Baltic grey seal population is direct descendants of this recolonisation. Our study highlights the power of biomolecular archaeology to understand the factors that shape contemporary marine diversity.

Forskningsöversikt (refereegranskat)abstract
- The middle of the first millennium AD in Sweden witnessed significant changes in the archaeological record, prompting various discussions about the underlying causes. This paper reviews the research developments surrounding the global climate cooling, which was caused by severe volcanic eruptions in AD 536/540 and is referred to as the Late Antique Little Ice Age or Fimbulwinter, and its potential impacts, with a specific focus on Swedish Iron Age societies, drawing upon published climatic and archaeological data. Furthermore, it discusses the research gaps that impede a comprehensive understanding of the potential relationship between the AD 536/540 event and socioeconomic changes in Iron Age Sweden. Additionally, it suggests that isotopic analysis will offer additional insights and help bridge the research gap.

Tidskriftsartikel (refereegranskat)abstract
- Archaeological investigations and clear aerial photos have identified the presence of house foundations within several ringforts on the island of Öland, east of the Swedish mainland. One of them, Sandby borg, was selected for further investigations by means of a ground-penetrating radar (GRP) and magnetometry survey. A subsequent excavation was carried out to validate the geophysical results. The results of the geophysical survey clearly show the presence of 36 or 37 stone foundations for houses situated radially around the wall of the fort as well as of 16 or 17 similar house foundations in a central building group. The geophysical results also provided information on other buried features within the fort and also confirm the location of a third gate situated in the north-western part of the fort. The available evidence indicates that the ringfort was used for military purposes, or as a place of refuge in times of unrest, for a limited period of time during the late 5th century.

Dietary Variation in Arctic Foxes (Alopex-Lagopus) - an Analysis of Stable Carbon Isotopes
- 1994
-
Ingår i: Oecologia. ; 99:3-4, s. 226-232
-
Tidskriftsartikel (refereegranskat)abstract
- We used stable carbon isotopes to analyse individual variation in arctic fox diet. We extracted collagen from bones (the lower jaw), and measured stable carbon isotopes. The foxes came from three different localities: Iceland, where both microtines and reindeer are rare; west Greenland, where microtines are absent; and Sweden, where seat analyses showed the primary food to be microtine rodents and reindeer. The Icelandic samples included foxes from both coastal and inland habitats, the Swedish sample came from an inland area, and the Greenland sample from coastal sites. The spatial variation in the isotopic pattern followed a basic division between marine and terrestrial sources of protein. Arctic foxes from inland sites had delta(13)C values of -21.4 (Ice land) and -20.4 parts per thousand (Sweden), showing typical terrestrial values. Coastal foxes from Greenland had typical marine Values of -14.9 parts per thousand, whereas coastal foxes from Iceland had intermediate values of -17.7 parts per thousand. However, there was individual variation within each sample, probably caused by habitat heterogeneity and territoriality among foxes. The variation on a larger scale was related to the availability of different food items. These results were in accordance with other dietary analyses based on seat analyses. This is the first time that stable isotopes have been used to reveal individual dietary patterns. Our study also indicated that isotopic values can be used on a global scale.

Tidskriftsartikel (refereegranskat)abstract
- The trophic structures of tundra ecosystems are often viewed as a result of local terrestrial primary productivity. However, other resources can be brought in through long-distant migrants or be directly accessible in coastal areas. Hence, trophic structures may deviate from predictions based on local terrestrial resources. The Arctic fox (Vulpes lagopus) is a small canid that may use marine resources when available. We used stable isotope values in Arctic fox fur and literature data on potential prey to evaluate Arctic fox summer resource use in a mountain tundra without coastal access. The dietary contribution of local prey, presumably mostly rodents, declined with declining rodent abundance, with a subsequent increased contribution of migratory prey relying on marine resources. Stable isotope values did not differ between this terrestrial area and an area with direct coastal access during years of high rodent abundance, but isotope values during low rodent abundances suggested less marine input than in a coastal population feeding primarily on marine prey. Our study shows that marine resources may be used by animals in areas without any coastal access, and we highlight that such partial coupling of ecosystems must be included in the modeling and assessments of tundra environments.

Tidskriftsartikel (refereegranskat)abstract
- With the Neolithic transition, human lifestyle shifted from hunting and gathering to farming. This change altered subsistence patterns, cultural expression, and population structures as shown by the archaeological/zooarchaeological record, as well as by stable isotope and ancient DNA data. Here, we used metagenomic data to analyse if the transitions also impacted the microbiome composition in 25 Mesolithic and Neolithic hunter-gatherers and 13 Neolithic farmers from several Scandinavian Stone Age cultural contexts. Salmonella enterica, a bacterium that may have been the cause of death for the infected individuals, was found in two Neolithic samples from Battle Axe culture contexts. Several species of the bacterial genus Yersinia were found in Neolithic individuals from Funnel Beaker culture contexts as well as from later Neolithic context. Transmission of e.g. Y. enterocolitica may have been facilitated by the denser populations in agricultural contexts.

Dangerous food. Climate change induced elevated heavy metal levels in Younger Stone Age seafood in northern Norway

Tidskriftsartikel (refereegranskat)abstract
- Stable isotope and elemental analyses of the Atlantic cod (Gadus morhua) and harp seal (Phoca groenlandica) bone component of the marine food that dominated the Younger Stone Age (c. 6.1–3.5 ka BP) diet in Varanger, Arctic northern Norway, indicate, at times, climate change induced highly elevated levels of the heavy metals cadmium (Cd) and lead (Pb), and elevated levels of mercury (Hg). On average, the levels of cadmium and lead contamination in cod were up to 22 and 3–4 times, respectively, higher than today's recommended limits in soft tissue. The corresponding figures for seal were 15 and 3–4 times, respectively. The levels of Hg were generally below today's recommended limit in soft tissue, but still of considerable magnitude, almost similar to the measured values in modern fish in the Arctic. This shows that marine food in the Younger Stone Age was unhealthy, if not unsafe. We discuss this unexpected knock-on effect in terms of sea surface temperatures and sea level change. The elevated values may have been detrimental for humans, if not for society; a balancing factor may have been a larger component of terrestrial resources than previously assumed. Concomitantly, this contribution to the paleo base-line record of toxicity may lead to predictions for seafood contamination in the future.

Ancient genomics of Baltic seals : Insights on the past Baltic grey seal and harp seal populations
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis aims to study and describe the ancient populations of grey and harp seals in the Baltic Sea, and to present new methodological approaches for general use in ancient DNA studies.The dissertation is comprised of five studies: a review of the use of paleogenetics in studying ancient human-marine mammal interactions; a method paper investigating patterns of DNA preservation in ancient pinniped samples; a method paper presenting a genetic sex identification method for ancient pinnipeds; a population genomic study of the Baltic grey seal; and a population genomic study of the now extinct Baltic harp seal.Guidelines for ancient DNA sample selections were deduced from broad-scale statistical modelling of factors influencing DNA preservation in pinniped bones, the most significant of which included type of bone element, collagen content, and whether the bone derive from a cave context. Modern ringed seal samples with known sex were used to test an alternative pinniped sex identification method using the annotated dog genome as a reference for quantification of the relative representation of X chromosome reads. Reliable sex identification was shown to require a minimum of 5,000 total reads mapped to the reference genome. A total of 69 mitochondrial control regions were generated for Baltic grey seals, which revealed that the Mesolithic data largely represent extinct haplotypes, the main of which continued until the Early Neolithic. A population replacement prior to the early Bronze Age introduced mitochondrial variation resembling that of modern Baltic greys seals. The level of genetic differentiation between the Baltic harp seal population and the three contemporary breeding populations, suggests that the White Sea population is the most likely ancestor of the Baltic harp seal breeding population. An increase in genetic diversity, following a hiatus with no Baltic harp seals, combined with the measures of genetic differentiation from this period, further suggests that a second colonization likely occurred from the White Sea during the early Bronze Age.

Genomic insights on the extinct Baltic harp seal population
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The harp seal is a cold adapted seal species, which requires a suitable formation of pack ice during winter and spring to secure successfully breeding. Today harp seals live in sub-Arctic regions and the North Atlantic, but during the middle Holocene Period, a breeding population existed in the Baltic Sea. In order to investigate the genetic affinity and faith of the now extinct Baltic harp seal population we analysed contemporary and ancient mitogenomes from across the species contemporary and ancient range. Ancient mitochondrial genomes were generated for a total of 49 Baltic harp seals ranging from Late Mesolithic to the Iron Age, together with five Neolithic samples from the White Sea and two Neolithic samples from the Northwest Atlantic Ocean. The ancient data was compared to published modern harp seal data assigned to the present breeding populations around Newfoundland, the Greenland Sea and the White Sea. Surprisingly only limited phylogenetic resolution was found among the ancient and modern localities. The statistical measures for genetic differentiation, however, identified significant levels of population genetic differentiation between the Baltic harp seal population and all modern populations, which suggest an independent breeding population in the Baltic Sea. The low level of genetic differentiation to the White Sea population indicate a shared ancestry between the Baltic and White Sea. The generated Skyline plot suggest second wave of colonization after a hiatus in the Baltic Sea. Interestingly, the genetic diversity in the Baltic harp seal population was significantly higher than in any of the modern populations. However, a drastic decrease in genetic diversity is observed from the Bronze Age to the Iron Age, which might be linked to effects of high hunting pressure and climatic changes towards the final extirpation of harp seals in the Baltic.

The Strategic Environmental Archaeology Database : a resource for international, multiproxy and transdisciplinary studies of environmental and climatic change
- 2015
-
Konferensbidrag (refereegranskat)abstract
- Climate and environmental change are global challenges which require global data and infrastructure to investigate. These challenges also require a multi-proxy approach, integrating evidence from Quaternary science and archaeology with information from studies on modern ecology and physical processes among other disciplines. The Strategic Environmental Archaeology Database (SEAD http://www.sead.se) is a Swedish based international research e-infrastructure for storing, managing, analysing and disseminating palaeoenvironmental data from an almost unlimited number of analysis methods. The system currently makes available raw data from over 1500 sites (>5300 datasets) and the analysis of Quaternary fossil insects, plant macrofossils, pollen, geochemistry and sediment physical properties, dendrochronology and wood anatomy, ceramic geochemistry and bones, along with numerous dating methods. This capacity will be expanded in the near future to include isotopes, multi-spectral and archaeo-metalurgical data. SEAD also includes expandable climate and environment calibration datasets, a complete bibliography and extensive metadata and services for linking these data to other resources. All data is available as Open Access through http://qsead.sead.se and downloadable software. SEAD is maintained and managed at the Environmental Archaeology Lab and HUMlab at Umea University, Sweden. Development and data ingestion is progressing in cooperation with The Laboratory for Ceramic Research and the National Laboratory for Wood Anatomy and Dendrochronology at Lund University, Sweden, the Archaeological Research Laboratory, Stockholm University, the Geoarchaeological Laboratory, Swedish National Historical Museums Agency and several international partners and research projects. Current plans include expanding its capacity to serve as a data source for any system and integration with the Swedish National Heritage Board's information systems. SEAD is partnered with the Neotoma palaeoecology database (http://www.neotomadb.org) and a new initiative for building cyberinfrastructure for transdisciplinary research and visualization of the long-term human ecodynamics of the North Atlantic funded by the National Science Foundation (NSF).

Dealing With Reservoir Effects in Human and Faunal Skeletal Remains : Understanding the radiocarbon dating of aquatic samples
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Archaeology relies on the ordering of past events to study cultural developments. This has traditionally been achieved by looking at the stratigraphic depths of materials relative to one another. In this way, chronologies of past technological progressions and stylistic changes can be built. The introduction of radiocarbon dating in the 1950s revolutionised archaeology, allowing for direct, numerical estimates of a sample’s age. This allowed for more detailed past chronologies than was previously possible. Radiocarbon dating utilises the radioactive decay of carbon-14 (radiocarbon, 14C) to estimate a sample’s age with older samples having less 14C. Shortly after the introduction of radiocarbon dating, however, it was demonstrated that 14C is not evenly distributed globally. Typically, there is less 14C in marine (and sometimes freshwater) systems compared to the atmosphere. This results in aquatic samples appearing older than they are, a phenomenon known as a ‘reservoir effect’. When radiocarbon dating material from archaeological sites with marine activity, this is an important consideration. With aquatic resources being vital for human populations across the globe and for millennia, the ability to interpret aquatic radiocarbon dates is incredibly important. Making use of radiocarbon dates without properly handling any reservoir effects have proved problematic, sometimes resulting in archaeologically incorrect chronologies being constructed. Reservoir effects can, however, be managed. This thesis demonstrates how archaeologists should interpret radiocarbon dates from aquatic samples, avoiding erroneously-old age estimates. Through careful sample selection, considering complicated carbon source mixing, measuring the scale and variability of reservoir effects within a single ecosystem and using prior knowledge about a sample’s age, the dating of aquatic material can be greatly improved. This thesis also details a novel method of dating teeth, reducing uncertainty, and concomitantly estimating the extent of the reservoir effect. This was achieved by dating dental increments, combined with complex modelling. It is clear that there is no single method of handling reservoir effects, and methods for dealing with reservoir effects will differ depending on the archaeological site and specific research question. In this thesis, novel and existing methods of dealing with reservoir effects are demonstrated by considering five case studies from four archaeological sites:At the site of Hamanaka 2 (Rebun Island, Japan), it is demonstrated that by carefully selecting samples without reservoir effects, the dating of the stratigraphy of the site can be accurately modelled. Concerning the cemetery site of Rounala (northern Sweden), it is demonstrated that by carefully reconstructing complex human diets, the dating of humans can be modelled to a high resolution. This has implications for the understanding of the Church’s relationship with the cemetery. At the site of Ekven (Chukotka, Bering Strait) reservoir effect variability between species is carefully described. A more detailed understanding of regional reservoir effects allows for more accurate dating of human remains from the marine hunting Old Bering Sea culture. More accurate dating of human remains allows for the refining of existing Old Bering Sea culture chronologies. Finally, concerning the material from Resmo (Ӧland, Sweden), a novel dental wiggle matching model is presented as a possible method for reducing dating uncertainty in individuals with a marine dietary component.

Tidskriftsartikel (refereegranskat)abstract
- Marine reservoir effects (MRE) have the potential to increase the dating uncertainty of humans incorporating marine resources into their diets. Here we attempt a novel dental wiggle-match model to reduce dating uncertainty of seven individuals from the Resmo megalithic tomb (Öland, Sweden) and to test whether this model can be used to calculate MRE from a single tooth. Previous stable isotope ratio studies of these individuals demonstrated that their diets changed, between more or less marine protein, during the early years of their lives. Several incremental samples of dentine from each individual were subjected to radiocarbon dating and stable isotope ratio analysis. An OxCal model was designed that makes use of the known formation sequence of human teeth to reduce overall dating uncertainty. The new dental wiggle-match model is able to reduce overall dating uncertainty in all of the sampled individuals compared to more conventional 14C calibration methods. A utility of the dental wiggle model to estimate marine reservoir effects without associated faunal material is also demonstrated, with promising results.

Tidskriftsartikel (refereegranskat)abstract
- Human burials from the cemetery at the Rounala church, northern Sweden, were radiocarbon (C-14) dated to shed light on the use of the cemetery. Carbon, nitrogen and sulfur stable isotope analysis of bone collagen from 19 distinct individuals indicated that these individuals had a mixed diet consisting of freshwater, marine and terrestrial resources. Dietary modeling using FRUITS was employed to calculate the contributions of the different resources for each individual. These data were then used to calculate individual Delta R values, taking into account freshwater and multiple marine reservoir effects, the latter caused by Baltic and Atlantic marine dietary inputs, respectively. C-14 dating of tissues from modern freshwater fish species demonstrate a lack of a freshwater reservoir effect in the area. Two OxCal models were used to provide endpoint age estimates. The calibrated data suggest that the site's cemetery was most likely in use already from the 14th century, and perhaps until at least the late 18th century.

Tidskriftsartikel (refereegranskat)abstract
- Due to the marine reservoir effect, radiocarbon dates of marine samples require a correction. Marine reservoir effects, however, may vary among different marine species within a given body of water. Factors such as diet, feeding depth and migratory behaviour all affect the 14C date of a marine organism. Moreover, there is often significant variation within single marine species. Whilst the careful consideration of the ΔR values of a single marine species in a given location is important, so too is the full range of ΔR values within an ecosystem. This paper illustrates this point, using a sample pairing method to estimate the reservoir effects in 17 marine samples, of eight different species, from the archaeological site of Ekven (Eastern Chukotka, Siberia). An OxCal model is used to assess the strength of these estimates. The marine reservoir effects of samples passing the model range from ΔR (Marine20) = 136 ± 41–ΔR = 460 ± 40. Marine reservoir effect estimates of these samples and other published samples are used to explore variability in the wider Bering Strait region. The archaeological implications of this variability are also discussed. The calibrating of 14C dates from human bone collagen, for example, could be improved by applying a dietary relevant marine reservoir effect correction. For humans from the site of Ekven, a ΔR (Marine20) correction of 289 ± 124 years or reservoir age correction of 842 ± 123 years is suggested.

Moose genomes reveal past glacial demography and the origin of modern lineages
- 2020

Ingår i: BMC Genomics. - : Springer Science and Business Media LLC. - 1471-2164. ; 21:1
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Numerous megafauna species from northern latitudes went extinct during the Pleistocene/Holocene transition as a result of climate-induced habitat changes. However, several ungulate species managed to successfully track their habitats during this period to eventually flourish and recolonise the holarctic regions. So far, the genomic impacts of these climate fluctuations on ungulates from high latitudes have been little explored. Here, we assemble a de-novo genome for the European moose (Alces alces) and analyse it together with re-sequenced nuclear genomes and ancient and modern mitogenomes from across the moose range in Eurasia and North America.Results: We found that moose demographic history was greatly influenced by glacial cycles, with demographic responses to the Pleistocene/Holocene transition similar to other temperate ungulates. Our results further support that modern moose lineages trace their origin back to populations that inhabited distinct glacial refugia during the Last Glacial Maximum (LGM). Finally, we found that present day moose in Europe and North America show low to moderate inbreeding levels resulting from post-glacial bottlenecks and founder effects, but no evidence for recent inbreeding resulting from human-induced population declines.Conclusions: Taken together, our results highlight the dynamic recent evolutionary history of the moose and provide an important resource for further genomic studies.

Ancient-DNA reveals an Asian type of Mycobacterium leprae in medieval Scandinavia

Tidskriftsartikel (refereegranskat)abstract
- Leprosy is a chronic infection of the skin and peripheral nerves caused by the pathogen Mycobacterium leprae. Its impact on human populations and societies of the past as well as its phylogeographic patterns around the world – at least in modern times – has been well documented. This slow growing bacterium has been shown to exist in distinct ‘SNP types’ that occur in relatively defined parts of the globe. The routes that the disease followed in the past are, however, still uncertain. This study of ancient-DNA typing of archaeological human remains from Sweden dated to early Medieval times provides genetic evidence that a transmission of M. leprae ‘SNP subtype’ 2G – found mainly in Asia – took or had already taken place at that time from the Middle East to Scandinavia. This finding is unique in the history of leprosy in Europe. All human specimens from this continent – both modern and ancient – that have been tested to date showed that the one responsible for the infection strains of M. leprae belong to ‘SNP type’ 3, whereas our results show that there were some European populations that were hosts to bacteria representing ‘SNP type’ 2 of the species as well.

- Drawing on data from the megalithic tomb in Resmo on oland in the Baltic Sea, we use a multi-isotopic approach, involving the systematic treatment and modelling of extensive human and faunal isotopic data (C-14, C-13, N-15, S-34 and Sr-87/Sr-86), along with archaeological contextual evidence, to study change and interaction. The fact that people utilize aquatic resources necessitates modelling of the sulphur and strontium isotope data, to prevent the aquatic contribution from obscuring the local terrestrial signal. It was possible to demonstrate how the people buried in Resmo went through dynamic changes in diet, mobility patterns and cultural identity during more than two millennia of burial practice: from the incipient farmers of the Funnel Beaker Culture, through the cultural encounters and transitions during the Middle Neolithic, to the newcomers furthering intensified agriculture, trade and metal craftsmanship during the Bronze Age.

- Recent excavations at the sites of Strandvägen and Kanaljorden in Motala, Eastern Central Sweden, have unearthed complex and varied funerary remains from the Mesolithic. The two sites are situated on opposite banks of the river Motala Ström. While geographically close and roughly covering the same time span (c. 8000–7000 cal. BP), the funerary remains reveal differences and similarities in the treatment of the dead between the two localities. While at Strandvägen human bones were mostly found either scattered along the river bed or in inhumation graves, Kanaljorden contains wetland depositions of disarticulated skulls. We have conducted multi-isotope analyses of δ13C, δ15N, δ34S and 87Sr/86Sr of human and animal remains with the aim of reconstructing the dietary patterns, geographic provenance and mobility of the interred. A series of faunal reference samples and, in the case of 87Sr/86Sr, soil samples have been analysed in order to establish relevant isotopic baselines. The results show a protein intake dominated by aquatic resources, probably consisting of both freshwater and marine fish in varied proportions. The strontium isotope data indicate an interesting distinction between the individuals buried on either side of the river Motala Ström. Five out of six sampled individuals from Strandvägen have isotope ratios consistent with a local provenance, whereas ratios from seven out of eight Kanaljorden individuals indicate a non-local origin. The δ34S analysis proved problematic as a majority of the samples appear to be affected by diagenesis. This is probably the result of contamination by exogenous sulphur from surrounding fluvial and lacustrine sediments, as has previously been reported from other waterlogged sites.

- We present here a framework for using stable isotope analysis of bone and teeth to study individual life history. A sampling strategy and analytical approach for stable carbon and nitrogen analysis of bone and dentine collagen optimised for intra-individual purposes is put forward. The rationale behind this strategy, various requirements and constrains, and recommendations on how to modify it according to variations in material and analytical instrumentation, are discussed and explained in detail. Based on intra-individual data for 131 human individuals from Mesolithic and Neolithic sites in Northern Europe, we consider the sources and various kinds of variation one is likely to find, and how the data can be explained and transformed into an archaeologically meaningful interpretation. It is concluded that the use of stable isotope analysis to trace individual life history is not limited to carefully excavated, neatly preserved, single burials with articulate skeletal remains. Even collective burials, disturbed graves, disarticulated human remains in cultural layers, or other depositions that deviate from what is often considered as a proper burial, offer the possibility to look at individual life biographies.

Norm and difference : Stone Age dietary practice in the Baltic region
- 2003
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Stone Age research on Northern Europe frequently makes gross generalizations about the Mesolithic and Neolithic, although we still lack much basic knowledge on how the people lived. The transition from the Mesolithic to the Neolithic in Europe has been described as a radical shift from an economy dominated by marine resources to one solely dependent on farming. Both the occurrence and the geographical extent of such a drastic shift can be questioned, however. It is therefore important to start out at a more detailed level of evidence in order to present the overall picture, and to account for the variability even in such regional or chronological overviews. Fifteen Stone Age sites were included in this study, ranging chronologically from the Early Mesolithic to the Middle or Late Neolithic, c. 8300–2500 BC, and stretching geographically from the westernmost coast of Sweden to the easternmost part of Latvia within the confines of latitudes 55–59° N. The most prominent sites in terms of the number of human and faunal samples analysed are Zvejnieki, Västerbjers and Skateholm I–II. Human and faunal skeletal remains were subjected to stable carbon and nitrogen isotope analysis to study diet and ecology at the sites. Stable isotope analyses of human remains provide quantitative information on the relative importance of various food sources, an important addition to the qualitative data supplied by certain artefacts and structures or by faunal or botanical remains. A vast number of new radiocarbon dates were also obtained.In conclusion, a rich diversity in Stone Age dietary practice in the Baltic Region was demonstrated. Evidence ranging from the Early Mesolithic to the Late Neolithic show that neither chronology nor location alone can account for this variety, but that there are inevitably cultural factors as well. Food habits are culturally governed, and therefore we cannot automatically assume that people at similar sites will have the same diet.Stable isotope studies are very important here, since they tell us what people actually consumed, not only what was available, or what one single meal contained. We should not be deceived in inferring diet from ritually deposited remains, since things that were mentally important were not always important in daily life. Thus, although a ritual and symbolic norm may emphasize certain food categories, these may in fact contribute very little to the diet. By the progress of analysis of intra-individual variation, new data on life history changes have been produced, revealing mobility patterns, breastfeeding behaviour and certain dietary transitions. The inclusion of faunal data has proved invaluable for understanding the stable isotope ecology of a site, and thereby improve the precision of the interpretations of human stable isotope data. The special case of dogs, though, demonstrates that these animals are not useful for inferring human diet, since, due to the number of roles they possess in human society, dogs could deviate significantly from humans in their diet, and in several cases have been proved to do so.When evaluating radiocarbon data derived from human and animal remains from the Pitted-Ware site of Västerbjers on Gotland, the importance of establishing the stable isotope ecology of the site before making deductions on reservoir effects was further demonstrated.The main aim of this thesis has been to demonstrate the variation and diversity in human practices, challenging the view of a “monolithic” Stone Age. By looking at individuals and not only at populations, the whole range of human behaviour has been accounted for, also revealing discrepancies between norm and practice, which are frequently visible both in the archaeological record and in present-day human behaviour.

Tidskriftsartikel (refereegranskat)abstract
- The Mesolithic–Neolithic transition in north-west Europe has been described as rapid and uniform, entailing a swift shift from the use of marine and other wild resources to domesticated terrestrial resources. Here, we approach the when, what and how of this transition on a regional level, using empirical data from Öland, an island in the Baltic Sea off the Swedish east coast, and also monitor changes that occurred after the shift. Radiocarbon dating and stable carbon and nitrogen isotope analyses of bones and teeth from 123 human individuals, along with faunal isotope data from 27 species, applying to nine sites on Öland and covering a time span from the Mesolithic to the Roman Period, demonstrate a great diversity in food practices, mainly governed by culture and independent of climatic changes. There was a marked dietary shift during the second half of the third millennium from a mixed marine diet to the use of exclusively terrestrial resources, interpreted as marking the large-scale introduction of farming. Contrary to previous claims, this took place at the end of the Neolithic and not at the onset. Our data also show that culturally induced dietary transitions occurred continuously throughout prehistory. The availability of high-resolution data on various levels, from intra-individual to inter-population, makes stable isotope analysis a powerful tool for studying the evolution of food practices.

Genetic turnovers and northern survival during the last glacial maximum in European brown bears

Tidskriftsartikel (refereegranskat)abstract
- The current phylogeographic pattern of European brown bears (Ursus arctos) has commonly been explained by postglacial recolonization out of geographically distinct refugia in southern Europe, a pattern well in accordance with the expansion/contraction model. Studies of ancient DNA from brown bear remains have questioned this pattern, but have failed to explain the glacial distribution of mitochondrial brown bear clades and their subsequent expansion across the European continent. We here present 136 new mitochondrial sequences generated from 346 remains from Europe, ranging in age between the Late Pleistocene and historical times. The genetic data show a high Late Pleistocene diversity across the continent and challenge the strict confinement of bears to traditional southern refugia during the last glacial maximum (LGM). The mitochondrial data further suggest a genetic turnover just before this time, as well as a steep demographic decline starting in the mid-Holocene. Levels of stable nitrogen isotopes from the remains confirm a previously proposed shift toward increasing herbivory around the LGM in Europe. Overall, these results suggest that in addition to climate, anthropogenic impact and inter-specific competition may have had more important effects on the brown bear's ecology, demography, and genetic structure than previously thought.

Genomic insights into the population history of circumpolar Arctic dogs
- 2020
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The Siberian and North American Arctic have both borne witness to numerous migrations of humans and with them their dogs. This PhD thesis is based on whole genome data from 22 Siberian dogs and 72 North American Arctic dogs, in addition to 186 mitochondrial genomes Siberian and North American Arctic dogs. Mitochondrial genome data allowed for the identification of migration events that introduced distinct dog populations to North America, associated with different cultural complexes arriving to the region. A novel mitochondrial clade was also identified in dogs from eastern Siberia and Alaska. Genetic analysis was performed to confirm the macroscopic identification of fur used to make clothing in the Arctic in conjunction with stable isotope analyses to explore dietary differences of dog populations across the circumpolar region. The whole genome data generated for this PhD also detected and explored evidence for several gene flow events from West Eurasian dogs into the dogs of Siberia starting 10,900 BP. There was an additional gene flow event that introduced Near East related ancestry to the dogs of the Siberian Steppe before the Late Bronze Age. Dogs carrying this West Eurasian ancestry spread throughout Siberia, reaching northwestern Siberia by the Iron Age, by 2,000 BP. Further gene flow was detected later in Siberia from West Eurasia a thousand years later. North American Arctic dogs universally carry the Near East related ancestry that is seen in Siberian dogs starting in the Bronze Age, showing it had reached the Bering Strait before the ancestors of the Inuit departed Siberia for Alaska. Once in North America Inuit dogs experienced several other gene flow events from pre-contact subarctic dogs, modern European dogs, and wolves. The population structure seen in North American Arctic dogs reflects geography and the subsequent isolation as well as population turnover events associated with catastrophic epidemics in the dog populations. Finally, a simple method was developed to evaluate and remove human contamination from ancient DNA datasets originating from faunal taxa. All together this thesis has compiled genomic information from 94 Arctic dogs to shed light upon the genetic history of these dogs from the early Holocene through to the present day. This dataset has been able to provide insight not only into past dynamics of Arctic dogs but also a much needed resource for understanding and preserving the indigenous dog populations still present in the Arctic that face continued challenges of globalisation and climate change.

Tidskriftsartikel (refereegranskat)abstract
- A strong cultural connection exists between reindeer and modern Sámi identityand economy. Reindeer domestication is, however, a rather late event, andthere are many Sámi who live off resources other than reindeer herding. Theuse of stable isotope analysis on historic reindeer from different geographicareas can contribute to analysing both the processes involved in reindeer domesticationand different environmental utilization by the Sámi. In this study,reindeer bones from six different sites in northern Sweden, ranging in datefrom the 11th to the 20th century, were analysed for stable isotopes to studyhow reindeer have been utilized in various historic contexts – settlements,offering sites and a marketplace. The stable isotope analysis demonstrateddifferent practices in utilization of reindeer, such as foddering. Foddering issuggested to have caused the elevated δ15N values found in reindeer at theoffering sites Vindelgransele and Unna Saiva, as well as at the settlementVivallen. The analysis further indicates that the offering sites were used bysingle Sámi groups. An important outcome of our study is that the biologyof reindeer in Sápmi was culturally influenced by the Sámi even before thereindeer was domesticated.

- An unusual ski from the Låktatjåhkå / Loktacohkka glacier in Sápmi – Use, wax, 14C and lipid residue analysis: Archaeological skis dated from the Stone Age to today, are not unusual finds in bogs and wetlands. They are found all over Sápmi, from Norway to the Kola peninsula in the Russian federation. Skis are also represented in rock art at different sites in Sápmi and mentioned in written sources; however, skis found at higher altitudes, at glaciers and perennial snow patches, are not as common. In 2018, nine kilometers west of Björkliden, a fragment of a ski was found by the Loktačohkka glacier. The ski fragment was first 14C-dated to the 15th century; however, presence of vax on the fragment presented an interesting problem. A new 14C analysis of the ski fragment, with the wax components removed, now dated the cellulose from the ski to 1645–1916 CE, i.e. the ski could have been used some time from circa 1645 into the first half of the 20th century. This study highlights the importance of regular surveys of melting glaciers and snow patches to retrieve organic material melting out, as well as the importance of investigating what components wood could have been impregnated with.

- Vivallen is a Late Iron Age/Early Middle Ages South Saami site with a burialground as well as a large dwelling site in Härjedalen, Sweden, located in the borderland between Saami and Norse groups. As food can be used as an indicator of cultural affiliation, we investigated the relative importance of various foodstuffs at this site, performing δ13C and δ15N analysis of human and faunal skeletal remains. The site was located along the St Olaf pilgrimage route, implying that some of the buried individuals may not have been local to the site, and therefore we performed δ34S analysis to study mobility. We set out to investigate if there were any changes in diet and mobility over the lifespan of the people buried at Vivallen. The results showed that freshwater fish were an important part of the diet, whereas reindeer and big game do not seem to have been major proteinsources. We could not identify any substantial changes in diet in the individuals over time. Our results further demonstrated low mobility among the individuals,with one exception, a female who evidently grew up somewhere else.

Tidskriftsartikel (refereegranskat)abstract
- In this study, we used stable isotope analysis and radiocarbon dating to study diet, mobility and chronology in two late medieval/historical coastal populations in northern Norway. We have shown that the individuals buried at Kirkegardsoya date between 1331 and 1953 cal AD and had a homogenous marine diet, whereas the individuals buried at Gullholmen had a more heterogeneous diet, consisting of both terrestrial and marine proteins and date between 1661 and 1953 cal AD. We have demonstrated that reindeer protein was not an important part of their diet, and also discussed the importance of correcting for the marine reservoir effect in populations with a coastal subsistence. Our interpretation is that individuals buried at Kirkegardsoya primarily belonged to a Coastal Sami community, although Norwegians with a similar diet (and likely comprising a minor population in the area) cannot be ruled out. The more varied diet and mobility at Gullholmen could, as predicted, indicate that these individuals may have had a more diverse cultural affinity.

Food Cultures in Sápmi : An interdisciplinary approach to the study of the heterogeneous cultural landscape of northern Fennoscandia AD 600–1900
- 2020
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this thesis is to highlight the heterogeneous cultural landscape in Sápmi through the study of food. By studying food and the choices of specific foodstuffs in Sápmi AD 600–1900, a greater understanding can be gained on the history of this area during the period. A number of well-known archaeological sites in Sápmi have been chosen as the focus, dating from the Late Iron Age in north-central Sweden to the late-19th century in northern Norway. By means of stable isotope analysis (δ13C, δ15N, δ34S and 87Sr/86Sr) and elemental analysis on human and animal skeletal remains, the diversity in food culture has been studied. The chronological range in this thesis is rather broad but has been determined by the available archaeological skeletal material from the area. The overarching questions are how cultural diversity is reflected in different food practices, how individual life history and studies of mobility contribute to the understanding of life in Sápmi, what role the reindeer had in the diet in Sápmi during the period studied, and finally, what impact mining activities had on the local population in Sillbajåhkå/Silbojokk in terms of lead poisoning?Through the different case studies, it has been demonstrated that food consumption was by no means uniform and static during the period, and that the differences in food consumption reflect a multicultural landscape. Individuals buried in Vivallen had a diet based on terrestrial and freshwater resources, in contrast to individuals from Guollesuolu/Gullholmen and Kirkegårdsøya, who had diets based predominantly on marine protein. However, the diet of individuals buried at Gullholmen was much more varied than at Kirkegårdsøya, indicating a multi-ethnic presence. The intra-individual analysis of diet and mobility provided information on a more complex society. Whether they were Sámi or non-Sámi is difficult to assess, but they were clearly a culturally heterogeneous group of people. The individuals that were buried in Rounala and Sillbajåhkå/Silbojokk in northern Sweden had a mixed diet, including foodstuffs from terrestrial, freshwater and/or marine environments. The sites overlap chronologically, with Rounala dating from the 14th to the 18th century, and Silbojokk from the 17th to the 18th century. While individuals buried in Rounala had a mixed diet, focused on freshwater fish, individuals buried in Silbojokk had a much more varied diet. Through the analysis of sulphur and strontium isotopes, it was possible to investigate intra-individual change in diet and mobility. Further, the results indicated that reindeer protein was not a major food source at the sites studied.The mining activities at Silbojokk can be seen as the result of colonial infraction on nature and people in Sápmi by the Swedish state, with an immense and negative impact on the environment and for people there. This thesis includes the analysis and handling of human skeletal remains, which always has ethical implications: even more so in areas subjected to colonialism, such as Sápmi. My aim has been to highlight the importance of discussing reburial and repatriation and offer some thoughts on how this may be handled in the future.

- Established in 1635, the silver mine of Nasafjall and the smeltery site in Silbojokk in Swedish Sapmi were used during several phases until the late 19th century. Excavations in Silbojokk, c. 40 km from Nasafjall, have revealed buildings such as a smeltery, living houses, a bakery, and a church with a churchyard. From the beginning, both local and non-local individuals worked at the mine and the smeltery. Non-locals were recruited to work in the mine and at the smeltery, and the local Semi population was recruited to transport the silver down to the Swedish coast. Females, males, and children of different ages were represented among the individuals buried at the churchyard in Silbojokk, which was used between c. 1635 and 1770. Here we study diet, mobility, and exposure to lead (Pb) in the smeltery workers, the miners, and the local population. By employing isotopic analysis, delta C-13, delta N-15, delta S-34, Sr-87/Sr-86 and elemental analysis, we demonstrate that individuals in Silbojokk had a homogenous diet, except for two individuals. In addition, both local and non-local individuals were all exposed to Pb, which in some cases could have been harmful to their health.

- The silver mine of Nasafjäll and the smeltery site in Silbojokk in Swedish Sápmi were established in 1635 and was used during several phases until the late 19th century. Excavations in Silbojokk, c. 40 km from Nasafjäll have revealed buildings, such as a smeltery, living houses, a bakery, a church with a churchyard. Already at the start, both local and non-local individuals worked at the mine and the smel-tery. Non-locals were recruited to work in the mine and at the smel-tery, and the local Sámi population was recruited to transport the sil-ver down to the Swedish coast. Females, males and children of differ-ent ages were represented among the individuals buried at the church-yard in Silbojokk, used between c. 1635 and 1770. Here we study diet, mobility and exposure to lead in the smeltery workers, the miners and the local population. By employing isotopic analysis, δ13C, δ15N, δ34S, 87/86Sr and elemental composition, we have demonstrated that individ-uals in Silbojokk had a homogenous diet, except for two individuals. In addition, there were local and non-local individuals, and all of them were exposed to lead, that in some cases could have caused death. The environment at Nasafjäll and Silbojokk is still highly toxic.

Consuming and communicating identities : Dietary diversity and interaction in Middle Neolithic Sweden
- 2011
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Isotope analyses on human and faunal skeletal remains from different Swedish Neolithic archaeological contexts are here applied as a means to reconstruct dietary strategies and mobility patterns. The chronological emphasis is on the Middle Neolithic period, and radiocarbon dating constitutes another central focus. The results reveal a food cultural diversity throughout the period in question, where dietary differences in part correspond to, but also transcend, the traditionally defined archaeological cultures in the Swedish Early to Middle Neolithic. Further, these differences, and the apparent continued utilisation of marine resources in several regions and cultural contexts, can only in part be explained by chronology or availability of resources depending on geographic location. Thus, the sometimes suggested sharp economic shift towards an agricultural way of life at the onset of the Neolithic is refuted. Taking the potential of isotope analyses a step further, aspects of Neolithic social relations and identities are discussed, partly from a food cultural perspective embarking from the obtained results. Relations between people and places, as well as to the past, are discussed. The apparent tenacity in the dietary strategies observed is understood in terms of their rootedness in the practices and social memory of the Neolithic societies in question. Food cultural practices are further argued to have given rise to different notions of identity, some of which can be related to the different archaeological cultures, although these cultures are not to be perceived as bounded entities or the sole basis of self-conceptualisation. Some of these identities have been focused around the dietary strategies of everyday life, whereas others emanate from practices, e.g. of ritualised character, whose dietary importance has been more marginal. Isotope analyses, when combined with other archaeological indices, have the potential to elucidate both these food cultural aspects.

Bokkapitel (refereegranskat)abstract
- Strontium isotope analysis of skeletal material as a means to reconstruct prehistoric residential patterns has previously mainly been applied to populations with terrestrial diets. Here we present a model for populations with mixed marine/terrestrial diets, which is based on two-component mixing of strontium isotopes. Applying this model, we can estimate the original strontium isotope value of the terrestrial component of the diet. Accordingly it is possible to identify non-local individuals even if they had a mixed marine/terrestrial diet. The model is applied to tooth enamel samples representing nine individuals recovered from a passage grave in Resmo, on the island of Öland in the Baltic Sea, where at least five non-local individuals, representing at least two different geographical regions of origin, were identified. Non-local individuals were more frequent during the Bronze Age than during previous phases.

- The Middle Neolithic Pitted Ware Culture on the Baltic Sea islands comprised a common identity distinguished, in part, by an almost exclusively marine diet. Based on evidence from the first stable isotope analysis on Pitted Ware skeletal material from the Eastern Central Swedish mainland, we suggest that this identity was shared by PWC groups in the archipelago of the west side of the Baltic. Fifty-six faunal and 26 human bone and dentine samples originating from the Pitted Ware site Korsnäs in Södermanland, Sweden were analysed, and the data clearly shows that the diet of the Korsnäs people was marine, predominantly based on seal. The isotope data further indicate that the pig bones found in large quantities on the site emanate from wild boar rather than domestic pigs. The large representation of pig on several Pitted Ware sites, which cannot be explained in terms of economy, is interpreted as the results of occasional hunting of and ritual feasting on wild boar, indicating that the animal held a prominent position, alongside seal, in the hunting identity and cosmology of the Pitted Ware people. Further, eleven new radiocarbon dates are presented, placing the Korsnäs site, with a large probability, within Middle Neolithic A.

- Analyzing the δ2H values in individual amino acids of proteins extracted from vertebrates, we unexpectedly found insome samples, notably bone collagen from seals, more than twice as much deuterium in proline and hydroxyproline residues than inseawater. This corresponds to at least 4 times higher δ2H than in any previously reported biogenic sample. We ruled out diet as aplausible mechanism for such anomalous enrichment. This finding puts into question the old adage that “you are what you eat”.
