Evidence from several disciplines supports the proposition that following the Wisconsinan and an initial but brief moist phase of the Holocene, there was a gradual drying trend in the mid-continent Prairie Peninsula that peaked about 7000 years ago, a pattern that was not reversed until about 4000 years ago. Except for minor perturbations, conditions during the past four millennia have essentially been similar to those of the present. Studies in palynology and geomorphology have shown that the climatic regimes of the early/mid Post-glacial had a marked influence on both the biota and landscape erosional patterns, especially along the margins of the Prairie Peninsula. Measurable changes in the landscape and attendant biota show a time-transgressive pattern of drought related phenomena recorded palaeo-ecologically from west to east.Few studies of archaeological sites in the Prairie Peninsula have examined the evidence in and around the sites themselves for data reflecting local environmental dynamics. In fact, earlier models proposed for explaining the evolution of food-procuring systems in eastern North America virtually ignored potential changes in the natural environment. This paper examines data from two archaeological sites along the prairie-forest border in Missouri that contain long cultural sequences. Evidence is presented that pronounced changes in the natural environment occurred and that these biophysical variables are indeed critical for understanding the evolution of food-procuring societies in the American Midwest. 相似文献

An increasingly salient policy innovation pursued by LGBT+ rights groups and socially liberal policy entrepreneurs is the right of trans people to bring their legally recorded sex in line with their lived gender by way of self-identification. In response to these moves toward trans inclusion, a unique coalition of trans-exclusionary (gender critical) feminists and traditionalist conservatives has emerged to challenge these reforms. This coalition of policy opponents, mirroring historical issue frames that present homosexuals as predatory sexual deviants, campaign on a salient issue frame that presents transgender individuals and the expansion of trans rights as an inimical threat to the security, safety, and welfare of (cisgender) women, particularly in single-sex spaces. In this paper, we address two questions. First, we ask: do trans-exclusionary “protect women” issue frames over the alleged threat of trans persons to (cis) women shape mass public opinion? Second, we ask: in a relatively LGBT+ friendly policy environment, who supports the right to self-identification for trans individuals? We answer these questions via an original pre-registered survey experiment embedded within the 2021 Scottish Election Study. We find that trans-exclusionary issue frames appealing to (cis) women's safety significantly depress support for trans rights, particularly among women respondents. Highlighting these concerns is an effective means of increasing already robust opposition to reforms designed to improve the welfare of transgender individuals, which should be of concern for proponents of self-identification policies. 相似文献

The antiquity and context (site or feature type) are the two principal factors that act as a framework for interpreting charcoal and wood data from archaeological sites in the recreation of past woodland environments. This research addresses these parameters through the analysis of over 18,000 charcoal fragments from 57 archaeological excavations carried out along a 61?km road scheme in the midland region of Ireland. Observations on spatial vegetation dynamics and woodland resource patterns are also reported on. The data were analysed through percentage frequency and multivariate analyses. The results reveal woodland resource usage in terms of wood types selected for use as fuel or as structural wood as well as patterns of change and variability in taxonomic composition in relation to site types, feature types and time periods. Selection was found to be low in prehistoric times and in particular at burnt mound sites/fulachta fiadh but became increasingly important as time progressed. This has important implications when charcoal from archaeological settings is used in environmental reconstructions. 相似文献

This paper investigates the Mesolithic–Neolithic transition in the Channel Islands. It presents a new synthesis of all known evidence from the islands c.5000–4300 bc , including several new excavations as well as find‐spot sites that have not previously been collated. It also summarizes – in English – a large body of contemporary material from north‐west France. The paper presents a new high‐resolution sea‐level model for the region, shedding light on the formation of the Channel Islands from 9000–4000 bc . Through comparison with contemporary sites in mainland France, an argument is made suggesting that incoming migrants from the mainland and the small indigenous population of the islands were both involved in the transition. It is also argued that, as a result of the fact the Channel Islands witnessed a very different trajectory of change from that seen in Britain and Ireland c.5000–3500 bc , this small group of islands has a great deal to tell us about the arrival of the Neolithic more widely. 相似文献

While total global forest cover is decreasing, in many parts of the world forests are on the rebound. Uncritical examinations of this phenomenon credit the benign diffusion of capitalist development for this "forest transition." More critical readings of this question—including green Marxian and poststructuralist approaches—might conclude something very different, however. In this paper, we explore the question of expanding forest cover, using the case of the Scottish Highlands, where forestland has tripled since the 1920s, in an attempt to critically explain regional land–cover change. Drawing upon historical sources and Scottish Executive and Forestry Commission data, we examine the specific environments currently forming in the Highlands under conditions of economic change. We conclude that two divergent forestry practices and ecologies have been formed in the wake of economic restructuring: those geared towards industrial production and those targeted at consumption through ecotourism. We conclude, therefore, that capitalism's spatial fix to declining industrial power in the region is an inherently ecological one that takes the form of "schizophrenic forestry," in which forest expansion leads to the rise of degraded monocultures alongside "pristine" sites of conservation. 相似文献

A methodology is described by which spatial patterns of land use were reconstructed from pollen analyses on anthropogenic sediments at a recently excavated early Neolithic timber ‘hall’ in north east Scotland. The anthropogenic sediments were from a deep, small diameter pit within the building. They present numerous taphonomic and interpretative challenges to the analyst, but from this type of deposit, the power to estimate quantitatively the vegetation structure around the archaeological site makes such difficult deposits very significant. A rigorous methodology is firstly described, therefore, by which confidence in ecological interpretation can be established. Secondly, the source of pollen in the deposit is evaluated. Thirdly, the possible pollen source area and structure of the surrounding vegetation are estimated by quantitative simulation modelling. Finally, these analyses are compared with region-scale pollen analyses from nearby conventional wetland deposits with much larger pollen source areas. The pollen assemblages recovered probably reflect land uses adjacent to the ‘hall’ and up to 2.5 km around. Cereal cultivation was the most important land use immediately around the ‘hall’, possibly grown between stands of scrub Corylus (hazel) woodland. These intensive but local-scale land uses cannot be discerned in region-scale pollen analyses. 相似文献

Previous research probing early migrations and contacts in the Baltic Sea area is characterized by the analysis of different chronologies and subsistent strategies on all sides of the Sea. Several studies performed on artifact typology, ceramics, grave rituals and physical anthropology ended with varying results. Although the question of human origins remains inconclusive, in this study, we rely on the phylogeography of an animal associated with humans to elucidate findings regarding prehistoric human migration and contacts.Hedgehogs, along with other fauna on Gotland, were brought over to the island by humans. We examined hedgehog mitochondrial DNA from the Pitted Ware Culture (Middle Neolithic). The genetic signatures of the animals on the island were investigated to determine the animal’s origin.From the 23 bones originally examined, twelve bones from all five locations studied yielded reliable results and resembled published extant Erinaceus europaeus sequences from Sweden, Norway and Denmark. We postulate that a western heritage for the Neolithic hedgehogs on Gotland indicates early human contact with the Swedish mainland. 相似文献
