Paleoparasitological results from coprolites dated at the Pleistocene–Holocene transition as source of paleoecological evidence in Patagonia

Coprolites attributable to humans, dated from the Pleistocene–Holocene transition, obtained from the archaeological site Cerro Casa de Piedra, Santa Cruz Province, were examined for parasites. The feces were processed by rehydration and spontaneous sedimentation using conventional parasitic procedures. Helminthic eggs recovered were identified as Trichuris sp., Calodium sp., other capilariids, and ancylostomid (Nematoda), probably Hymenolepis sp. and anoplocephalid (Cestoda); one oocyst attributable to Eimeria macusaniensis (Apicomplexa) was also found. According to the life-cycles and specificity of the parasites found, it is possible to suggest that some species (i.e., E. macusaniensis and Calodium sp.) represent parasites in transit or pseudoparasitism. Paleoparasitological results revealed the existence of an intensive relationship between parasites and humans in the Pleistocene–Holocene transition in Patagonia. Evidence suggests an early association among parasites, rock shelters and hunter–gatherers in the region. It is also postulated that the ancient lifestyles associated with caves and rock shelters were conductive to illness.     

The archaeology and paleoenvironment of an Upper Pleistocene hyena den: An integrated approach

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.     

Renewable Electricity in the EU: Are We Meeting the Targets?

This paper analyses differences in the degree to which European Union countries have achieved the renewable electricity (RES-E) targets set by the European Commission for each Member State for 2010. After defining an RES-E target achievement (TA) indicator, both conventional and novel techniques are used to examine the main features of its distribution, including the degree of inequality, external shape and intra-distribution dynamics, for the 1996–2006 time period. The analysis demonstrates that disparities in TA have been strongly reduced and that intra-distribution mobility was very high.     

A Neolithic Voyage

Examination of stone artefacts from Maiden Castle, Dorset, led to the identification of a Neolithic saddle-quern which originated in central Normandy. While stone axes from Brittany and jadeitite axes from the Alps have long been known from central southern England, the quern is the largest and heaviest Neolithic import yet identified. It has a bearing on the debate about indigenous or immigrant origins for the Neolithic, but also re-opens the question of the type of boat that plied the Channel at this early period. It is argued that logboats, for which there is evidence, should not be overlooked in favour of skin-boats for which there is none.

Trust and Confidence: A Study of Young Queenslanders

This paper provides a unique perspective on trust in Australian society using data from the first wave of a longitudinal study of young people in Queensland. Questions central to young people's expectations regarding institutions and significant others are interrogated. Trust assumes critical importance in this context because it is an important aspect of the future-oriented deliberative processes young people engage in. Gender, indigenous status and religiosity are key determinants of trust across a range of indicators. Boys are less likely than girls to trust significant others such as friends and siblings or to trust environmental groups, but are more trusting of sportspeople, television and the Internet. Aboriginal children are more trusting of their siblings, teachers and neighbours, but less so of their parents. ‘Smart’ children are more trusting of their teachers and schools and feel more confident about their future, while general life satisfaction is positively associated with most measures of trust.     

From the Opposite Corner: A Bibliometric Analysis of Research on American Archaeology in European Publications

We see what we are prepared to see. Scientific research aims at breaking down this situation, analysing its subjects/objects of study from different points of view. Although multiple meanings can be derived from every question and a myriad of positions can be adopted, some are bound to be silenced by traditional criteria of authenticity. Archaeology is not an exception to this: the prevailing agenda severely impacts on our perception of what archaeological practice consists. In turn, its ethos is recreated as part of our own identity processes through our productions, whether by passively accepting monolithic standards or by dynamically proposing alternative positions in response. The study of the prehistoric and colonial periods in America can be a good test bed for surveying the influence of academic background upon the analysis of human history. Here we review two Spanish journals of American studies to discuss the different orientations of the authors according to their provenance. Plotted against the country represented by the authors, we consider his/her research as regards the object of study (ie. artefacts/written sources), its origin, chronology and, finally, the aim of the paper. We found interesting orientations in relation to focus on particular subjects, most probably conditioned by the ontology of the researchers. Although the selection is quite taxative, it may usefully complement studies carried out in the Americas.     

The reconstruction of past environments through small mammals: from the Mousterian to the Bronze Age in El Mirón Cave (Cantabria,Spain)

El Mirón is a large cave in the Cantabrian Cordillera of northern Spain that presents a long archaeostratigraphic sequence radiocarbon-dated by over 60 assays to between 41,000 and 2000 BP. The sediments, collected from four areas within the cave and sieved-washed with fine wire meshes, contain microvertebrate remains of fish, frogs, lizards, birds and mammals, of which the latter are most abundant. Preliminary taphonomic analysis suggests that the microvertebrates were naturally collected by owls and (less) small carnivores. Small mammal assemblages are useful for palaeoenvironmental reconstruction because they are linked to particular habitats and are sensitive to environmental changes. The small mammals from El Mirón are ideal for this because sample sizes are large, bone preservation is good, and the stratigraphic sequence is long. In this paper we reconstruct the late Quaternary environments in the Cantabrian region of Spain using small-mammal assemblages from El Mirón Cave. On the basis of the ecologic adaptations of this suite of fauna, the majority still extant, we have identified seven habitat types, which are plotted through time. The evolution of the small mammal assemblages at El Mirón reveals seven major climatic shifts that correspond closely to the climatic changes recognized in the Iberian Peninsula during the last 41 kyr.
