Data of high resolution for reconstructions of archaeological site formation processes can be obtained only by the use of precise excavation methods and comprehensive recovery techniques using fine-mesh water screening, followed by meticulous sorting and quantitative studies of all the small organic components from the screens. These methods are generally used at human occupation sites, but are not often employed at paleontological or mixed human-carnivore sites. At the site of Bois Roche, an Upper Pleistocene hyena den, we have used these meticulous recovery techniques in combination with absolute dating, geoarchaeological observations, taphonomic analyses, studies of microvertebrates and pollen analysis. Correlation of the site environmental data from pollen and microvertebrate assemblages with the vegetation record of a deep-sea core taken in the Bay of Biscay have allowed us to constrain the ages provided by ESR dating of bovid teeth and to reconstruct the physical environment of the site with a degree of confidence rarely achieved by the use of fossil remains from archaeological sites alone.  相似文献

Radiocarbon dates on marine shells have not been used as extensively as charcoal or bone dates for the setting up of absolute chronologies because interpreting these dates is complicated by the marine radiocarbon reservoir effect. Nevertheless marine shellfish were used widely at least during the Holocene and their shells are abundant and usually well preserved in archaeological deposits located near shorelines. Consequently prior research concerning the oceanographic conditions and the marine radiocarbon reservoir effect of a particular coastal area is needed in order to set up reliable chronologies for that region. Values of regional marine radiocarbon reservoir effect – ΔR – of coastal waters off Atlantic Iberia, some of its variability along the Holocene and its correlation with the upwelling phenomenon were determined during previous research. More data related to the ΔR values for western Portuguese coastal waters during the Late Neolithic and the Chalcolithic, a time interval badly sampled in previous research, were recently obtained. These values can be compared with ΔR values already determined for the Gulf of Cadiz. Besides the importance of these values for a better knowledge of the palaeoceanography and palaeoclimatology of Atlantic Iberia, from now on archaeologists can set up reliable chronologies for Late Neolithic and Chalcolithic contexts using marine shell samples of that origin for radiocarbon dating.  相似文献

Archaeological surface finds are difficult to date. There are several useful methods, but each requires special circumstances and has one drawback or another. On the west coast of South Africa marine shell are abundant on surface sites but they are rarely dated because they are perceived to be in disturbed context and in questionable association with artefacts. This paper attempts to rectify this misconception and shows that, although far from perfect, a large suite of surface dates can shed as much light as excavated data. On the Vredenburg Peninsula they help refute the hypothesis that two economically and culturally distinct populations shared this pre-colonial landscape since 2000 BP.  相似文献

Adult discourses often represent relationships between children and animals as beneficial for children's psycho-social development or as reflecting a ‘natural’ connection between children and animals. In contrast, this paper draws on recent work in sociology and geography where human–animal relationships are seen as socially situated and where conventional constructions of the human–animal boundary are questioned. Focussing on children's own perspectives on their connections with animals, it is argued that these relationships can also be understood within the social and relational context of children's lives. It is argued that this ‘relational’ orientation to children's relationships with animals might significantly enhance our understanding of children's lives and also open up ways of thinking about the place of animals in children's (and adults') social lives.  相似文献

Abstract

Middens of the southern British late Bronze and Iron Age are vast accumulations of cultural debris that can be explained as refuse dumps linked with large periodic feasting events. A distinctive feature of these sites is that their faunal assemblages invariably comprise a considerably higher proportion of pig remains than contemporaneous settlement sites. This paper presents results from a programme of stable carbon (δ13C) and nitrogen (δ15N) isotope analysis of fauna from two major midden sites, Llanmaes in South Wales and Potterne in Wiltshire. The research aim is to reconstruct husbandry strategies and foddering regimes, particularly concerning pigs, to better understand how the challenges of raising large herds were met. Analysis produced exceptionally wide-ranging results for pigs and other domesticates at both sites, particularly in terms of δ15N values, demonstrating that diverse foddering strategies were employed. Diversity in the late Bronze Age pig foddering regimes indicates that the Neolithic husbandry practices (focusing on woodland fodder) had not been abandoned, but that new husbandry methods (consumption of household waste) were also being practised, which subsequently became more widely established in the Iron Age. The heterogeneity of signatures suggests that animals may have been husbanded in a piecemeal fashion at a local, household level. This in turn hints that fauna may have been brought to these sites from households across the surrounding landscape, rather than being husbanded by specialist producers in the vicinity of the middens.  相似文献

Ongoing human–long-tailed macaque (Macaca fascicularis) conflicts in Bukit Timah Nature Reserve, Singapore, have seen native macaques significantly affected, as residential development encroaches into animals' habitat, destroying important wildlife corridors. The search for a more humane treatment of these transgressive animals can be seen as an attempt to extend and include non-human animals within humanistic notions of ethics and care, in the process destabilizing the assumed divide between human/animal. Yet, a feasible solution is difficult to reach as National Parks Board (NParks), the state agency overseeing the conservation of reserves and wildlife, has to negotiate constantly between their goal of maintaining biodiversity and appeasing the complaining residents. The paper seek to understand urban–wilderness conflicts between human–macaque, showing that the divide between tamed/wild is multi-sited, ambiguous and constantly shifting. In this regard, we are especially interested in the role of intermediaries in initiating actions to ‘make discursive as well as material space’ for macaques in the reserve. Intermediaries, here referring to NParks and animal activists, are actors who do not reside near the reserve thus having no frequent encounters with wildlife, yet are enrolled as mitigators during instances of human–animal conflicts.  相似文献

This article offers a canine history of the “critical period” concept, situating its emergence within a growing, interdisciplinary network of canine behavior studies that connected eugenically minded American veterinarians, behavioral geneticists, and dog lovers with large institutional benefactors. These studies established both logistical and conceptual foundations for large-scale science with dogs while establishing a lingering interdependence between American dog science and eugenics. The article emphasizes the importance of dogs as subjects of ethological study, particularly in the United States, where some of the earliest organized efforts to analyze canine behavior began. Further, the article argues that the “critical period” is important not only for its lasting prominence in multiple fields of scientific inquiry, but also as a historiographical tool, one that invites reflection on the tendency of historians to emphasize a particular narrative structure of scientific advancement.  相似文献

The last quarter of a century saw the international political community make concerted efforts to regulate global caviar trade and prevent illegal harvesting of critically endangered sturgeon. Ironically, the regulations have enabled the emergence of novel forms of illicit trade which intertwine legal and illegal streams of caviar on the international marketplace. This paper foregrounds these licit-illicit interfaces and argues that the international caviar trade constitutes a ‘grey market’ characterized by a host of laundering practices that entangle legal and illegal caviar flows. Drawing on geographical scholarship on political animals and fleshy geopolitics, the paper theorises how the fleshy material properties of caviar, namely its chemical-isotope profile and composite form, directly shape the European caviar grey market. By highlighting how the materiality of caviar creates grey interfaces between legal and illegal caviar economies, the paper unsettles dominant dichotomized representations of illegal caviar trade which tend to foster overwhelmingly securitized policy-enforcement approaches in Europe. In pointing to the hidden ‘fleshy geopolitics’ surrounding EU enforcement strategies, the paper calls for a reshaping of policy and enforcement which better attends to the grey dimensions of the caviar market and provides increased protection for wild sturgeon populations and marginalised communities located at the Eastern borders of Europe.  相似文献
