To continue to explore the impact of past human activity on the stable nitrogen isotope ratios of modern vegetation, we have measured the δ15N values of plants now growing on several ancient farmsteads in the Western Settlement of Norse Greenland. Although this new test area is some 400 km north and in a different ecoregion from the previous study area, the same isotopic effect was observed. A clear isotopic signature was found on the ancient farms which could be directly correlated to past activity areas; in particular, the infields. Further, the magnitude of the δ15N values was found to be similar between study areas, indicating the same interpretative framework can be applied in widely separate geographic regions. A first test of different plant species showed that although the magnitude differed greatly the same basic information was found for functionally different plants. These observations provide additional information to aid in future archaeological application of this newly observed phenomenon. 相似文献

The socio‐economic relevance of domesticated animals during the Early Neolithic in the Iberian Peninsula is indisputable, yet we essentially know little about the way they were managed. Among domesticated animals, pig (Sus domesticus ) was a common food source, and previous studies have shown the potential of stable isotopes for assessing variability in pig diet in relation to husbandry practices. Nevertheless, this approach has never been applied to the earliest pigs in the Iberian Peninsula. We analysed the carbon and nitrogen stable isotope composition of pig bone collagen from several Early Neolithic sites in the NE Iberian Peninsula. While pig δ13C values were similar across different populations, there were significant differences in δ15N values between sites. These are attributed to different pig husbandry systems, which may reflect distinct social and spatial organisation and interaction with environmental conditions during the Early Neolithic in this region.

Carbon and nitrogen isotope profiles were obtained from incremental dentine analysis of 19 non-adults from a cemetery in Riga, Latvia. The research compared the life histories and diet between people buried in two mass graves and the general cemetery. The δ13C profiles of several children from the mass graves were similar but did not resemble the patterns seen in children from the general cemetery, suggesting that they probably represented a different population group. The rise in δ15N values towards the end of the life of four individuals from one mass grave suggests they were victims of an historically documented famine. 相似文献

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. 相似文献

Current knowledge about the Mesolithic–Neolithic transition in the Central and Western Mediterranean European regions is deeply limited by the paucity of Late Mesolithic human osteological data and the presence of chronological gaps covering several centuries between the last foragers and the first archaeological evidence of farming peoples. In this work, we present new data to fill these gaps. We provide direct AMS radiocarbon dating and carbon (δ13C) and nitrogen (δ15N) stable isotope analysis were carried out on bone collagen samples of two single burials from the recently discovered open-air Late Mesolithic site of Casa Corona (Villena, Spain). The results shed new light on the chronology and subsistence patterns of the last Mesolithic communities in the Central Mediterranean region of the Iberian Peninsula. Radiocarbon results date the human remains and funerary activity of the site to 6059–5849 cal BC, statistically different from other Late Mesolithic sites and the earliest Neolithic contexts, and bridging the 500 yrs chronological gap of the Mesolithic–Neolithic transition from the area. Isotopic evidence shows that diet was based on terrestrial resources despite the proximity to the site of lagoon and marine ecosystems. This and previous isotope studies from the region suggest a lower reliance upon marine resources than for Atlantic and Cantabrian sites, although intra-regional patterns of neighbouring Mesolithic populations exhibit both fully terrestrial diets and diets with significant amounts of aquatic resources in them. We hypothesize that in the Central Mediterranean region of Spain the Late Mesolithic dietary adaptations imposed structural limits on demographic growth of the last foragers and favoured rapid assimilation by the earliest Neolithic populations. 相似文献

Carbon and nitrogen isotope analysis was undertaken on collagen extracted from eel bone from six Mesolithic and Neolithic sites in northern Europe. The results were compared with data obtained on other archaeological fish remains and modern eel caught in fresh and brackish water and from the sea. The possibility of discriminating between freshwater, brackish and marine signals in archaeological eel bone is evaluated and the implications for archaeology discussed. Our data suggest that eel found at coastal Mesolithic and Neolithic sites have carbon isotope signals consistent with a marine origin with no evidence of freshwater residency. The sample of eel bone from one inland site is small but indicates carbon isotope values more consistent with freshwater residency or at least values intermediate between freshwater and marine carbon pools. 相似文献

Stable isotope ratios of carbon and nitrogen in bone have become increasingly frequent inclusions in archaeological reports over the past few decades. The majority of such studies has been done in North America, where the use of marine foods and the introduction of maize have been monitored. Similar questions have been addressed in Mesoamerica and South America. In Europe, stable isotope ratios have documented the shift from marine fishing and gathering to agriculture in coastal areas and the introduction of millet in parts of eastern and southern Europe. Much work remains to be done in Asia, where millet replaced early C3 plant foods and, in turn, was replaced by rice. In Africa marine adaptations, freshwater fishing, agriculture, and pastoralism all yield diagnostic isotopic signatures. We review these studies, discuss areas requiring further study, and close with discussions of areas promising interesting future developments. 相似文献

Most native plants of Ontario use the C3 photosynthetic mechanism and therefore have relatively low ratios; maize is a C4 plant and is relatively enriched in 13C. The proportion of maize in the diet of a human can therefore be estimated from the 13C-content of collagen of fossil bone. We have used this method to follow the increase in consumption of maize in ancient native populations over the interval from AD 400 to 1650, and to quantify the amount of maize consumed. Maize consumption rose gradually to a maximum of 50% of the diet by AD 1400. These data agree with archaeologically derived data for this region, and with previous isotope studies in the northeastern U.S.A. In some of the latter, however, the maximum percentage of maize consumed has been overestimated because maize was assumed to have a δ13C value of ?12·5‰; our studies of archaeological specimens show the correct value to be closer to ?9‰. The introduction of beans into the native diet about AD 1100, should have caused a decrease in the 15N content of human bone collagen because legumes are deficient in this isotope, with respect to meat and fish. However, we observe no significant change in the N ratio of human bone collagen over the period from 2300 BC to AD 1640. We conclude that meat and fish remained the main sources of protein even after the advent of agriculture into this region. 相似文献

From the 16th century onward, various European nations shared fishing spaces off the coast of Newfoundland in an effort to provide salt-fish products to supplement increasing European demand. Faunal remains excavated at seasonal and permanent Newfoundland fishing stations indicate that pigs were the primary mammal species consumed by cod fishermen. It is not clear whether these pig remains derive from salt pork and/or live pigs imported from Europe or, rather, from pigs bred and raised in Newfoundland. Based on the notion that Newfoundland-raised pigs would have had greater access to marine-derived foods from nearby fisheries compared to their European-raised counterparts, we analyzed stable carbon and nitrogen isotope values from 28 pigs and 117 other faunal specimens from Dos de Cheval (EfAx-09) and Ferryland (CgAf-02) in order to identify individuals with marine or terrestrial isotope dietary signatures. Results indicating two distinct groups of pigs with mean δ13C and δ15N values differing by ∼6‰ and ∼9‰, respectively, suggest differing pig-product origins at each site. This method for identifying the transatlantic origin of pig remains has potential to shed light on patterns in the provisioning of the early European transatlantic fishing industry and inter-community relations. It may also allow for the development of more sophisticated body part representation models for zooarchaeological reconstruction of barreled salt pork use. 相似文献
