We synthesize and discuss available isotopic data on Holocene guanaco samples from southern South America, extending from Tierra del Fuego Island to northern Patagonia and the Pampean region. We evaluate temporal and spatial tendencies on the basis of 91 samples (mainly based on δ13Ccollagen values), presenting implications for paleodietary research in archaeology. We conclude that there are no strong correlations with latitude in the macro-spatial scale, while there is a set of interesting patterns at smaller regional scales. These patterns lead us to evaluate the role of ecologic and topographic variables (e.g. canopy effect, variations in altitude, ecotones) in structuring isotopic variability. Finally, on the basis of the present analysis we suggest a number of hypotheses and perspectives for the use of stable isotopes as geographic tracers of guanaco distribution in the past, and specific implications for the paleodietary study of human samples.  相似文献

Two significant events in the late Holocene history of Madagascar were (a) the arrival of people, and (b) the loss of nearly two dozen species of land vertebrates in the socalled “subfossil extinctions”. The consensus is that the faunal losses occurred shortly subsequent to human arrival, but the timing of these events is poorly constrained. The minimum age for initial human presence on the island may now be set at approximately 2000 bp, on the basis of AMS 14C dates for human-modified femora of extinct dwarf hippos from SW Madagascar. Assuming that this date also marks the beginning of deleterious human interactions with the subfossil fauna, and assuming that this fauna became completely extinct by 900 bp, the width of the anthropogenic “extinction window” may have been as long as c. 1000 a. This estimate, nearly twice the length of previous ones, is close to the unadjusted minimum for the duration of the terminal Pleistocene extinction event in the Americas. Whether or not this length of time comports with theoretical expectations of a “blitzkrieg” pattern of losses is uncertain, but greater refinement in dating the end of the subfossil extinctions is unlikely to produce radically shorter estimates of duration.  相似文献

The remains of the Kwäd?y Dän Ts'ìnch? individual, a frozen male human, were recovered from a retreating glacier within the Tatshenshini-Alsek Park in British Columbia in August 1999. In order to provide information on both the geographical origin of this individual and low long he spent in the remote interior region prior to his death, molecular analysis and compound-specific carbon isotope analyses were performed on individual amino acids purified from his skin and bone. Gas chromatographic quantification of constituent amino acids of both tissues revealed a molecular distribution characteristic of collagen, dominated by glycine and to a lesser extent proline, hydroxyproline and alanine. Chiral gas chromatography indicated that protein preservation in both tissues was exceptional. Carbon isotope analysis of a faunal assemblage from an earlier prehistoric site from southern British Columbia provided reference dietary amino acid δ13C values for terrestrial (deer and domestic dog) and marine species (salmon and sealion), showing clear separation in all amino acids, particularly glycine which was extremely 13C-enriched in the marine animals. The distinction between terrestrial and marine organisms was increased by exploring Δ13CGlycine-Phenylalanine values (6.6 ± 0.6‰ and 15.0 ± 2.1‰, respectively), which were higher in the latter by approximately 8‰, mirroring the increased δ15NBulk collagen values observed for the marine animals (R2 = 0.78; p < 0.001). The Kwäd?y Dän Ts'ìnch? individual's bone had a similarly elevated Δ13CGlycine-Phenylalanine value of 15.6 ± 1.0‰, indicating his extreme reliance on marine dietary resources throughout early life. The skin amino acid δ13C values were consistently lower than those observed for bone, with a concurrently lower Δ13CGlycine-Phenylalanine value of 12.7 ± 0.9‰. The shift between the carbon isotope composition of bone (long-term diet) and skin amino acids (short-term diet) confirmed a sudden divergence away from marine food sources in the last months of life, consistent with his discovery 80 km inland.  相似文献

An extraordinarily well-preserved skeleton of a child, interred in a stone sarcophagus in the Late-Roman era, was discovered in the city of Mainz (Germany) in 1998, covered with a puff pastry-like substance assumed to be adipocere. It is the first time that this substance, which is derived from fat under oxygen-deficient conditions and prevents corpses from decaying, has been discovered on corpses buried under conditions described in the present paper.  相似文献

Sections of human hair from naturally desiccated Sudanese Nubian mummies representing X-Group (AD 350-550) and Christian (AD 550-1300) periods in the Wadi Halfa area have been analysed for their isotope ratios. Because the carbon in hair represents food intake over the growth period of this tissue, analysis comparing segments taken next to the scalp with those further along the shaft can indicate diet just prior to death as well as any recent shift in food consumption. Modern populations in this area practise seasonal crop scheduling which involves the cultivation of C3 plants (wheat, barley and most fruits and vegetables) in the winter and the hardier C4 plants (sorghum and millet) in the summer. Shifting isotopic values along the length of hair strands of the ancient inhabitants of this area demonstrate that this practice has its roots at least as far back as the Initial Phase of Intensive Agriculture. The most common season of death appears to have been summer, the time of greatest climatic, nutritional and physiological stress for both ancient and modern inhabitants.  相似文献

Jet has been widely used in the past for jewellery but was just one of a range of black lithic materials employed. When worked into small objects these materials can be visually indistinguishable, yet discrimination is important because of the restricted occurrence of jet. X-ray fluorescence (XRF) is a rapid non-destructive discriminatory technique, but not all samples are clearly classified, and inhomogeneity may pose problems. A reassessment of the use of XRF is reported. Other techniques considered include electron spin resonance, infrared spectroscopy, Raman spectroscopy, thermogravimetric analysis, scanning electron microscopy and X-radiography. These were tested on geological materials to define an effective methodology for archaeological material. The recommended approach is a combination of XRF and X-radiography, although preliminary Fourier transform infrared results showed promise. The X-ray techniques were tested on Romano-British assemblages from Catterick and Stanwick.  相似文献

Abstract

Relations between the Catholic Church and the secular authorities of the Duchy of Warsaw were characterized by the one’s efforts to maintain its old privileges, and the other’s modernization of the law in a Josephist spirit. Cooperation and compromise between Church and state were possible, but their relations were full of tension, which sometimes erupted into open confl ict. This article presents a wider range of problems than has hitherto been noted in the historiography. From the beginning of 1807, the Catholic clergy was expected to fulfi l new duties, because of the shortage of administrative staff. Confl icts arose over the duties of patrons, payments for the clergy, their taxes, the government’s prohibition on plural holding of benefi ces cum cura animarum, and over ecclesiastical organization in general. The place of the Church was more clearly outlined in the Constitution of the Duchy of Warsaw (1807), but the concept of the ’state religion’ was seen by some clergymen as an opportunity to spread the Church’s infl uence. Further changes opened the higher ecclesiastical ranks to commoners. The civil government and the episcopate also differed on the role of religious orders, with the former looking to employ nuns and monks in social welfare and education. Bishops complained of ministers and offi cials who did not pay priests’ salaries punctually, if at all, but some episcopal interventions led to the authorities releasing the orders from fi nancial obligations and taxes. The Civil Code, introduced in 1808, assigned the duties of registrars to priests. Insofar as divorces and civil marriages were concerned, this role could place priests in contravention of canon law, although in practice almost no such cases occurred. Despite the work undertaken by representatives of the clergy and the civil authorities, no concordat, which would have resolved these issues, was agreed with the Holy See. As a result, the period of the Duchy brought the Catholic clergy great insecurity, alongside their hopes for the Polish nation.  相似文献

Abstract

Mass public commemoration of war dead is often held to be a twentieth-century phenomenon, with its genesis in the Great War. This article argues for a pre-history occasioned by commemoration of the South African War (1899–1902) that built on shifts in the form and function of war memorials that had begun in the middle of the nineteenth century.  相似文献
