Advancing the Analysis of Past Human/Plant Relationships: Methodological Improvements of Artefact Pollen Washes

The ‘pollen washes’ technique, based on the analysis of the pollen embedded in the porous surface of archaeological artefacts, is developed for investigating past plant usage and consumption and to characterize the functionality of artefacts related to plant processing, gathering and storage. The research presented results in relevant methodological improvements of this technique, which has never previously been applied on materials from European contexts. The improvements allow: (1) faster analysis of a broad series of artefacts or those with large use‐surface areas likely to retain more pollen; and (2) a more thorough, deeper and precise cleaning method, allowing the study of smoother artefacts. Finally, the recovery of Trifolium‐group pollen from a macro‐lithic tool from Xicotó rock shelter (Montsec ranges, Spain) demonstrates that the pollen washes technique can reveal new insights into both the use and consumption of wild and domestic plants by prehistoric societies, and the functionality of archaeological objects whose interpretation is still problematic.     

Identifying food provenience using Sr/Ca ratio in human enamel

The strontium (Sr) concentration in bioapatite of human bone and teeth reflects the Sr concentration in food that is differentiated by two major factors: an abundance of Sr in local soils and the biopurification effect along the trophic levels. Eastern Syria is an area with a relatively high concentration of Sr within the Euphrates valley and a low concentration of Sr beyond the valley. For this reason, the strontium/calcium (Sr/Ca) ratio in human enamel retrieved from skeletons buried in cemeteries within the Euphrates valley may be used as a proxy for food provenience in a local population. A sample of human teeth (N = 72) from Tell Ashara and Tell Masaikh was divided into seven temporal subsets covering periods between c.2200 bce and the early 20th century ce . A significant difference in Sr/Ca values between temporal subsets is observed. The Sr/Ca values in later subsets are negatively correlated with δ¹³C values, indicating the wider exploitation of steppe areas outside the valley with more wild C4 grasses and a low Sr concentration. For periods with lower Sr/Ca values (c.2200–1900 bce and 19th–20th centuries ce ) there is additional textual and isotopic evidence for food transportation from outside the river valley, supporting the interpretation of Sr/Ca values as a proxy for food provenience in this specific area.     

A spatial approach to upland vegetation change and human impact: the Aber Valley,Snowdonia

Abstract

Uplands have long been considered important ‘barometers’ for human-environment relationships. Five pollen sequences from the upper Aber Valley (Snowdonia), across an altitudinal gradient, reveal that human impacts have varied temporally on small spatial scales in the region. Woodland taxa persisted into the later Holocene at lower altitudes and sites located at higher altitude reveal a more open landscape history, possibly as a result of increased exposure limiting tree growth at high elevation. Continuous pastoral human land use is evident in the high upland (400 to >600 m AOD) landscape with evidence of clearing, burning and grazing indicators throughout the records covering the last ～6000 years, with increased activity apparent during the last 2000 years. There is no clear evidence to suggest that climate change (e.g. deteriorating climatic conditions from ～850 BC) resulted in land abandonment and it appears more likely that climatic shifts could have led to changes in human land management. The results demonstrate that pastoral land use varied at different altitudes across the Aber Valley upland, and have highlighted the value and potential of high/fine spatial sampling in providing insights into land use history and the mosaic of habitats that result.     

Thousand years of vegetation history revealed by pollen in a sandy soil,central Netherlands

Abstract

Within the scope of an interdisciplinary research project to determine the genesis and age of small clusters of oak trees, three soil sections in and three outside oak clusters in an ancient woodland/heath on the Veluwe, central Netherlands, were sampled for palynological analysis. The sections within the clusters show an undisturbed development from the Medieval period onwards, the sections outside the clusters are missing ca. 15 cm because of sod cutting associated with plaggen soil formation. The rate of downward movement of pollen was established, using known dates from the near surroundings.     

Two new camerate crinoid species from the Permian of eastern Australia

The habitat and habit of Australia's first recorded Tertiary marsupial species, Wynyardia bassiana, found some 130 years ago at Wynyard on the northwestern coast of Tasmania, remain enigmatic (Aplin 1987, Aplin &; Rich 1990). Fossil pollen and spores preserved in a rafted clast of estuarine silts from the same sequence of earliest Miocene marine sandstones as the skeletal remains indicate the local vegetation was Nothofagus-gymnosperm evergreen rainforest, probably with a cryptogam-rich rather than woody subcanopy stratum. Comparisons with present-day Nothofagus rainforests suggest that, although the subcanopy would have been sufficiently open to allow the passage of a large ground-dwelling herbivorous marsupial, limited food resources are more consistent with Wynyardia being a generalist arboreal herbivore.     

Testing micro-regional variability in the Holocene shaping of high mountain cultural landscapes: a palaeoenvironmental case-study in the eastern Pyrenees

Previous research acknowledges the ancient and complex land-use history of European mountainous areas, which are characterised by a remarkable regional variability in terms of human practices and patterns of occupation during the Holocene. However, the combined palaeoenvironmental and archaeological study of highland human management at a micro-regional scale remains a largely unexplored research field, especially in the Pyrenees. A combined pollen, stomata, non-pollen palynomorphs (NPPs) and macrocharcoal study was carried out at three nearby alpine and subalpine peat basins from a relatively small territory (ca.1700 ha) at the Madriu valley (Andorra, eastern Pyrenees), following a fine spatial-resolution strategy. The purpose was to test the suitability of high altitudinal palaeoecological sequences when reconstructing past small-scale land-use variability. The palaeoecological results of those peat records are compared and further integrated with archaeological local data, and together underline the marked complexity of high mountain land-use system over the Holocene period. Main phases of micro-regional land-use and landscape variability can be distinguished from the middle Neolithic to the early Bronze Age and from the Roman Period to the Modern Era. Conversely, several phases of homogeneous landscape management are distinguishable during the early Neolithic, and from the late Bronze to the late Iron Age. Results drawn from this study show that landscape variability is not necessarily connected to topographic or climatic parameters, and underline the role of social, economical and cultural parameters in the land-use organisation and the landscape shaping of high mountain spaces since Prehistory.     

Exploitation,fascist violence and social cleansing: a study of Franco's concentration camps from a comparative perspective

One of the most noticeable topics within recent Spanish historiography is the analysis of processes of mass violence. Salient among these were the Franco concentration camps, a violent re-educational system made up of more than 180 camps, 104 of which were permanent. The camps operated from 1936 until 1947, under the control of Franco's army, with its corresponding regime of forced labour and exploitation of prisoners of war. Half a million Spaniards and Europeans experienced first hand the Spanish version of the fascist concentration-camp system. This article offers an analysis of the inside history of Franco's concentration camps and then locates them comparatively within a theoretical and empirical Fascist model of internment, exploitation and violence.     

Rich–Poor Gap in Maternal Care

This paper examines the rich–poor gap in antenatal and delivery care in Northeast India on the basis of household economic well-being index constructed from household amenities, housing quality, consumer durables owned and assets. The study uses data on frequency of antenatal checks, iron folic supplementation, receiving two doses of tetanus toxoid injection and skill of delivery attendant from the Indian National Family Health Survey-II (1998–99). The finding reveals an unimaginably low level of maternal care in the region. Besides, there is evidence of concentration of women without adequate maternal care amongst the poorest economic strata. The need for region specific equitable maternal care services is suggested for the inaccessible northeastern region of India.     

Geographical Concentration of Manufacturing Industries in China: The Importance of Spatial and Industrial Scales

Using the most recent data from the first economic census in China, a team of China-based and American economic geographers investigates the geographical concentration of manufacturing industries at the provincial and county levels by integrating proxy variables for natural advantages, agglomeration economies, and institutional changes (e.g., decentralization) associated with economic transition. The authors focus their investigation on manufacturing activity as a whole, as well as on manufacturing categories at the two- and three-digit levels of aggregation (the latter representing a finer scale of analysis than used in almost all previous studies). Interesting differences emerge in the locational patterns of industries whose enterprises pursue strategies of globalization vis-à-vis local protectionism. Differences also are apparent in the impacts of agglomeration economies and knowledge spillover at different spatial scales. The findings suggest that both spatial scale and level of industrial aggregation matter when analyzing patterns of industrial agglomeration in China.
