To discern the presence of two anatomically close species within an archaeological assemblage is always a problem for the analyst. A particularly interesting case is the distinction between the red fox (Vulpes vulpes) and the arctic fox (Alopex lagopus), which is often determined using non-rigorous criteria and producing results that must be regarded with caution. Classical methods for separating these two species and determining sexual dimorphism, and eventually the sex ratio, such as analyses using uni- and bivariate plots, are based on arbitrarily fixed limits between sexes. In this text, a more robust statistical method termed mixture analysis (MA) is used to determine the species of limb bones from foxes. First, the MA is applied to a sample of each species using metric data taken from a collection of present-day fox skeletons. Afterwards, the MA is applied to archaeological samples dated to the Dorset period and retrieved from the Tayara site (near Salluit, South Hudson Strait, Nunavik). The results clearly demonstrate that the greatest length (GL) of long bones, especially the humerus and tibia, is the best measurement for distinguishing the species, followed by the distal breadth and the proximal breadth; and that GL is better suited for sexing foxes. The results of MA applied to the Tayara site collection lead to the conclusion that the red fox is present along with the arctic fox among the assemblage, and that there is no fox body size change during the last two millennia in the Eastern Arctic.  相似文献

This is an invited to response to K. Ryan’s comments on Coltrain et al. (2004) and Coltrain (2009). Both publications present stable isotope data and AMS radiocarbon dates on a suite of eastern Arctic burials from three sites in north-western Hudson Bay. In these articles, we examined the importance of bowhead whaling among Thule foragers at Silimiut and Kamarvik and contrasted their subsistence strategies with those of the proto-historic Sadlermiut, using the stable and radio-isotope chemistry of purified bone collagen to monitor variability in resource acquisition over time. Ryan dismisses a Dorset-era radiocarbon date on a burial collected by Collins from the T-1 site asserting that a single radiocarbon measurement is not a reliable indicator of age and thus the burial is Sadlermiut not Dorset. She also contests our assessment that two historic-era individuals in the Sadlermiut mortuary assemblage were either European or consumed diets relatively high in European foods. Ryan further argues that our reconstruction of protohistoric Sadlermiut diets is not in keeping with the archaeofaunal record. Her primary concern is a perceived lack of agreement between a subset of our findings and the archaeological record.  相似文献

The popularity of physical geography at all levels of formal education is declining. This paper argues that a key factor in the decline may be the disparity between geographies studied within formal education and the popular geographies encountered during leisure pursuit. Through the example of the Jurassic Coast Project, an initiative for the interpretation of Dorset's coastal landscape, approaches towards the integration of popular and academic geographies are explored. Drawing explicit links between popular experiences and academic knowledge may benefit physical geography, improving its status amongst public and student audiences, and addressing the concerns that surround its decline within higher education.  相似文献

The debate in the house of lords on 'No Peace without Spain' in December 1711 was the first test of the strength of the administration of Robert Harley, earl of Oxford, in the upper House. Though there are more sources for this debate than is normal for proceedings in the Lords, few can claim to be by eyewitnesses. A newly 'discovered' anonymous letter from an eyewitness found in the papers of the lord great chamberlain's office in the Parliamentary Archives gives a detailed account of this important debate.  相似文献

Upon the discovery and protection of a presumed 16th-century wreck off Poole Harbour, one of the largest underwater excavations in England was carried out between 1984 and 1992. In 1997–8 the author examined the archive and recovered objects with the aim of publishing the present report on the hull remains. The paper demonstrates how much can be learned about construction and design from in-situ recording. The similarities and differences between this vessel and other vessels of the so-called Iberian-Atlantic building tradition are analysed, and rigging modifications suggested. The vessel has never been scientifically dated, but a typological date bracket is based on onboard artefacts.  相似文献
