An island-wide assessment of the chronology of settlement and land use on Rapa Nui (Easter Island) based on radiocarbon data

The archaeological landscape on Rapa Nui (Easter Island) contains a palimpsest of surface archaeological features reflecting a long history of settlement and land use. The popular narrative of societal collapse prior to European contact relies on chronometric data from the late pre-European contact period and also cites major settlement shifts as evidence for societal collapse and socio-political reorganization. This paper explores the archaeological evidence for proposed changes in settlement by assessing the spatial and temporal distribution of radiocarbon determinations collected from archaeological and landscape contexts. A corpus of over 300 determinations is placed into an island-wide GIS database and analysed. The results of this study suggest that Rapa Nui settlement and land use exhibit continuity rather than punctuated, detrimental change during the late pre-European contact period.     

Evaluation of uniradicular teeth for age-at-death estimations in a sample from a Pampean hunter-gatherer cemetery (Argentina)

Age-at-death estimation is one of the most important aspects of bioarchaeological and forensic investigations. A set of analysis carried out with the osteological sample recovered from Chenque I site (Lihué Calel National Park, La Pampa province, Argentina) aims to test the applicability of multiple methods to obtain reliable information about its demographic composition and structure. In the present paper the results of the evaluation of the structure of uniradicular teeth are presented and discussed. It has been previously stated that chronological age is highly correlated with pulp dimensions in these teeth, because dentine deposition continue during all life. Strong correlation has been also identified with periodontal retraction and apical translucency. The analysis of the structure of these teeth offers useful information in order to obtain age-at-death estimations of the individuals they belonged to. Dental age-at-death estimations of the control sample were obtained evaluating some skeletal markers (pubic symphysis and auricular surface of coxae), and then compared with the dental analysis. The formulae whose results showed strong correlations with the skeletal estimations were applied to another sample, composed of teeth that were not associated with any skeletal marker of age. The evaluation of premolars and lower central incisors offers estimations that are consistent with those obtained from the evaluation of the pelvic bones, so that the application of these formulae is an alternative method to obtain estimations in archaeological samples from similar contexts.     

The Early Bronze Age settlement of Fidvár,Vráble (Slovakia): reconstructing prehistoric settlement patterns using portable XRF

This paper presents first results of chemical analyses of sediment samples from the Early Bronze Age (EBA) settlement Fidvár near Vráble (Slovakia). Large-scale geomagnetic prospection revealed detailed architectural remains of a fortified settlement. Other structures such as an earthwork of the linear pottery culture and at least two Roman march camps were found too. An Auger programme provided sediment samples of different depths, A) from an EBA house and the outer fortification ditch, B) from a potential metal workshop area as indicated by surface finds, and C) from an area located in the settlement's centre. The samples were analysed by a portable X-ray fluorescence (pXRF) spectrometer in order to investigate the vertical and horizontal distribution of chemical signatures. The comparison of geophysical data and three-dimensional chemical patterns gives us the opportunity to determine the human impact and to reconstruct activity patterns. The potentials and limits in the application of pXRF in archaeological soil chemical surveys are evaluated by systematic comparisons with high resolution laboratory measurements, including atomic absorption spectrometry (AAS) and inductively coupled plasma optical emission spectrometry (ICP-OES). The pXRF analyses can be reproduced well and show a good accuracy. Whilst (p)XRF analyses reflect the total composition of archaeological soil samples, the results of the AAS and ICP-OES analyses are fundamentally influenced by the acid digestion or extraction methods used. The pXRF analyses of the Vráble soils showed typical patterns of human occupation. For example, there are strong positive correlations between phosphorous, strontium and calcium. Phosphorous shows an enrichment in pathways and the fortification ditch. It is less strongly enriched within the sediments of house structures. Similar results apply to calcium and strontium distribution. But compared to the respective concentrations in sediment samples from the ditch they show a considerably higher variation in samples associated with house structures; that is, individual samples of sediments from house structures contained high concentrations of both, calcium and strontium. The deposits of an area that according to surface finds was thought to represent a potential metal workshop did not show indicative chemical signatures. Targeted excavations confirmed the absence of such as workshop. Finally it was shown that the refill history of the innermost fortification ditch (sample area D) and the overall cultural occupation sequence at the site correlate strongly with the chemical signatures of the respective ditch profile. The systematic variation of key elements along the profile opens up an entirely new perspective for interpreting the site's history. Overall, the study shows the great potential of pXRF as valuable part of an archaeological survey toolkit.     

Deletion/Substitution/Addition (DSA) model selection algorithm applied to the study of archaeological settlement patterning

This paper introduces GIS-based statistical methods for the study of settlement patterning in an archaeological context. The main aspect is an improvement over suboptimal stepwise statistical model selection procedures, with the introduction of a Deletion/Substitution/Addition (DSA) algorithm, a systematic model selection algorithm that provides an optimal model choice. The paper also introduces the combined use of Receiving Operator Characteristic (ROC) curves, and variable ranking as key tools aimed at an understanding of settlement patterning causation. An illustrative case study is provided whereby both a purely environmental and a mixed environmental/historical model (based on settlement hierarchy considerations) are investigated.     

Prehistoric land use and hydrology: a multi-scalar spatial analysis in central Arizona

Human land-use strategies involving the management of rainfall and runoff to promote crop production are found throughout the world. This paper presents a functional assessment using hydrological modeling with modern high-resolution LiDAR datasets and contextual archaeological site data to study prehistoric agriculture. The focus is on rock alignments created by the Hohokam culture in the semi-arid environment of the US Southwest. By incorporating a multi-scalar GIS study for terrain analysis at a regional, community, and site scale, the complex interactions between the prehistoric sites, features and the environment are revealed. The results of these analyses on digital elevation models (DEMs) gave insight to the past functionality of such agricultural features within the cultivated landscapes. The results included:1) The agricultural features were suitably placed for the collection of rainfall and runoff.2) The features were reducing the volume of water flowing through the area to prevent flooding and crop destruction and promoting soil infiltration.This shows the complexity and innovation of prehistoric societies living in marginal environments and how their adaptation to such environments was necessary to sustain their populations.     

From pedologic indications to archaeological reconstruction: deciphering land use in the Islamic period in the Baida district (north-western Sicily)

The aim of this work was to detect imprints on soil properties from former Islamic land use (9th to 11th century) using a multi-method, soil-chemical approach. Four soil profiles (with buried horizons) found in the vicinities of former Islamic settlements in Sicily were analysed for phosphorus (total, organic and inorganic), nitrogen (total, NO₃⁻ and NH₄⁺), carbon compounds (δ¹³C, lipids, polycyclic aromatic hydrocarbons (PAH) and functional groups), physical and chemical C-fractions and the state of soil weathering. Two soil profiles contained ceramic sherds from the Islamic period. Inorganic nitrogen forms, phosphorous and the PAH content indicated strong impacts from traditional agriculture and/or burning. Radiocarbon dating of soil organic carbon (SOC) fractions from buried horizons showed that distinct changes must have occurred during the Islamic epoch. The isotopic composition of SOC indicated that land use was probably different in earlier times. C₄ plant cultivation was expected but surprisingly lipid analyses did not confirm this. A high amount of aliphates and low C/N ratio indicated a good, long-term SOC stabilisation under the native conditions combined with Islamic land use. The irrigation of the soils probably increased the production of weakly-crystalline Fe forms that helped to stabilise SOC.     

Dietary patterns during the early prehispanic settlement in La Gomera (Canary Islands)

The dietary pattern of 10 adults interred in the Acceso al Pescante de Vallehermoso cave (La Gomera, Canary Islands), dated from 1600 to 1800 years BP, has been investigated using carbon and nitrogen stable isotope signatures, bone barium and strontium levels, and dental and oral pathologies. In addition, trabecular bone mass – as a parameter useful to evaluate overall nutrition – was also determined.     

Roman Rhine settlement dynamics evidenced by coin distribution in a fluvial environment (Oedenburg,Upper Rhine,France)

On the basis of archaeological and alluvial records, this paper presents the first spatial analysis of artefacts in relation to the evolution of the Rhine River, at the Gallo-Roman site of Oedenburg, during the first four centuries AD. The dataset consisted of several thousand Roman artefacts found by pedestrian prospecting over the last twenty years, over half of which were coins. This dataset was used together with high-resolution topography and geomagnetic mapping, to reconstruct settlement evolution, both on the terrace and in the floodplain. A comprehensive monetary chart has been compiled for the Oedenburg site, which highlights four major phases of settlement. These results provide a possible causal link connecting historical factors and alluvial events with intra-site evolution. Therefore, while changes observed during Phases I (until AD 68), II (AD 69 to AD 180) and III (AD 180 to AD 295) seem largely related to historical and societal events, Phase IV (AD 295 to AD 402) shows patterns of abandonment of the lower part of the floodplain that may well be related to an unusually humid period in the fourth century. These results are set in a broader context, from the Rhine catchment area to the Alps, and are in agreement with the wet conditions also documented in alluvial, lacustrine, geomorphological and palynological records in Germany (Lahn River, Lake Constance, Lake Nussbaumen, Kaisersthul area and the Black Forest). Studying the intra-site spatial distribution of artefacts with high temporal constraints, at a long-lived site with contrasted topography, opens new avenues for the detection of discreet events such as a higher water table, affecting only the lower zone.     

Using toponymy to reconstruct past land use: a case study of ‘brüsáda’ (burn) in southern Switzerland

Toponyms are frequently the outcome of a creative process, a subjective interpretation by the local inhabitants at the time of naming. They often survive changes in the local landscape, thus becoming historical documents of landscape dynamics or changes in land use. In this contribution we provide a systematic synchronic analysis of the toponym brüsáda (burn) in Canton Ticino. In total, 182 instances of place names containing brüsáda were recorded, of which 102 cases (56.0%) were localised. Based on oral information provided by the local people or on archival documents, it was possible to group the selected toponyms into different meaning classes such as burnt building, exposed sites, pasture-land and others without any indication (classified here as generic). On the basis of etymological, topographic, documentary, bibliographic, and historic evidence, as well as proxy-archives (such as charcoal in lake sediments), we hypothesise that most of the toponyms associated with pasture-land – and probably also a large portion of the generic toponyms – are directly or indirectly related to the habit of using fire to clear brushwood to improve pasture-land or to eliminate trees. In the study area, the practice of pasture-fires appears to have been a very well controlled and targeted activity in medieval times. In contrast, pasture-fires became very frequent and uncontrolled in the second half of the nineteenth century up until the Second World War. Our study confirms the usefulness and suitability of toponymy, in combination with other disciplines, for ecohistorical reconstructions of past environmental and land-use changes.     

Organization of ceramic production at a fortified Early Bronze Age settlement in Moravia (Czech Republic) inferred from minimally destructive archaeometry

This paper explores how pottery production was organized at fortified sites of central Europe at the end of the Early Bronze Age. The organization of pottery production in terms of ethnography-based models was inferred jointly by non-destructive multi-elemental analysis, micropetrography and powder X-ray diffraction. This minimally destructive approach was used to explore the mode of pottery production at the fortified central site Blu?ina (Moravia, Czech Republic). Archaeometry-based indirect evidence indicates that tableware of a specific shape was produced using a specific technology at the site or in its close vicinity and that coarse ware was brought to the site from elsewhere. The results obtained were complexly evaluated and compared with ethnography-based categorizations to reveal the features of production organization of the Early Bronze Age pottery. Multidimensional analysis classified the production as intensified household labour and work of individual retainers, or nucleated corvée, depending on its scale and intensity.     

Mobility or migration: a case study from the Neolithic settlement of Nieder-Mörlen (Hessen,Germany)

A combination of stable carbon and nitrogen isotope analysis of collagen and radiogenic strontium isotope analysis of tooth enamel was used to investigate diet and mobility at the early Neolithic settlement of Nieder-Mörlen in Germany. The carbon and nitrogen ratios suggest a mixed terrestrial based diet that is consistent with data previously published for early Neolithic sites in Europe. The strontium isotope data indicate a high degree of human mobility with only one individual having an isotope ratio consistent with locally derived strontium. Unusually, a group of non-local juveniles with isotope ratios typical of upland regions is also present at the settlement but there are no adult burials with such values. Whilst transhumance is considered as an explanation, it would not explain why these non-local juveniles lived foreshortened lives and other possible mechanisms are therefore discussed.     

The impact of traditional land use on woodlands: a case study in the Spanish Central System

We analyse the consequences of traditional use on forest characteristics during the last millennium in a mountain area of Spanish Central System, using information contained in documents, as well as cartography and toponymy. In the Middle Ages the local forests were transformed into municipal dehesas (communal fenced woods), communal wood pastures and arable lands. Pinewoods located in areas above 1500 m decreased because of the high grazing pressure. In the fifteenth century two manors were created (Buitrago and Montesclaros). Livestock became an important factor during this period. As a consequence an open wood was formed and oak coppices were also abundant (the felling of this species was at that time permitted by the Ordinances). At the end of the period of traditional management, pinewoods were disappearing and the main forest areas were located only in municipal dehesas. The area of beech was reduced in favour of melojo oak and scrub, due to the lower sprouting capacity of the beeches and their lower drought tolerance. Open wood pastures remain only in the eastern part of the study area, where there has been less intense human intervention. After the abolition of manors in the nineteenth century, arable land increased in the western part of the area, which had a higher population density. In the twentieth century, both human and livestock pressure decreased substantially and pine species were reintroduced by reforestation. The primitive savannah was transformed into ‘infilled savannah’, while temperate species spread around their refuges in municipal woods.     

Accessing Hunter-Gatherer site structures using Fourier transform infrared spectroscopy: applications at a Taltheilei settlement in the Canadian Sub-Arctic

The results of Fourier transform infrared spectroscopy on soils and caribou bone from a Taltheilei culture settlement in northern Canada contribute to developing micro-archaeological approaches suitable for locating and characterizing hearth and midden features on hunter-gatherer sites. A weak yet pervasive signal for montgomeryite was developed from the diagenesis of dispersed ash and caribou processing residues. Disordered calcite, carbonate hydroxylapatite, charcoal, and burned bone in two pit-house hearth deposits indicate that both wood and bone were used for fuel. Crystallinity indices and carbonate/phosphate ratios for bone indicate high intensity burning. These data, in tandem with the presence of semi-subterranean dwellings, demonstrate that this particular tundra-based encampment was occupied during cold seasons, a type of settlement behaviour previously unrecognized in the Taltheilei archaeological record. Our results confirm that Fourier transform infrared spectroscopy is an accessible, rapid, and cost effective means of discovering micro-archaeological evidence valuable for reconstructing hunter-gatherer site structures.     

Vegetation,land, and wood use at the sites of Bat and Al‐Khashbah in Oman (fourth–third millennium BC)

About 4200 charcoal fragments have been identified from the fourth‐ to third‐millennium BC archaeological sites of Bat and Al‐Khashbah in order to gain an understanding of plant resources available at the sites. Acacia sp., Ziziphus sp., and Tamarix sp. were the main taxa identified at both sites and indicate a similar vegetation composition as today. Phoenix sp. (date palm) charcoal also has been found at both sites. Whereas the cultivation of date palm for the 2700–2300 BC layers from Bat was likely, given other circumstantial evidence (i.e. local cereal cultivation and floodwater irrigation), it is unclear whether date palm was cultivated at Al‐Khashbah. Especially for the older periods (3300–2700 BC) it is possible that nomadic pastoralists were exploiting and/or managing wild date palms. The find of Avicennia marina at Al‐Khashbah indicates long‐distance contacts with the coast.     

工业发展与城市变化:明中叶至清中叶的苏州(中)

五、明清苏州城市的人口变化道光《苏州府志》卷10说晚明的苏州府,“聚居城郭者十之四五,聚居市镇者十之三四,散处乡村者十之一二”,亦即城市人口占到全府人口的十分之八九。虽然这个说法无疑有夸大,但城市人口在苏州府总人口中所占比重很高则是可以肯定的。苏州府本是明清江南城市化水平最高之处,而苏州地区（即吴、长、元三县）又是苏州府内城市化水平最高的地区。仔细来看,在本文所研究的三个世纪中,苏州城市人口有很大变化。对于这个变化,我们也从府城与郊区市镇两个方面来进行考察。（一）府城的人口变化明代后期苏州府城（城…     

工业发展与城市变化:明中叶至清中叶的苏州(下)

七、工业发展与城市变化之间的关系　　早在半个世纪以前 ,宫崎市定就已深刻地指出 :明清时期的苏州 ,“不仅是一个政治城市 ,而且还是一个商业城市 ,并逐渐变化为一个轻工业城市” 。这个结论十分正确 ,因为到了清代中期 ,仅只就工业中的一个部门———丝织业而言 ,就成为了苏州府城的经济支柱。正如后人所言 :“有清一代 ,苏垣东半城几全为丝织业所聚居……地方经济之荣枯 ,亦几视丝织业之兴衰为断” 。这里我们要强调的是 ,虽然宫崎氏所说的苏州仅只是苏州府城 ,但是他的这个结论同样也适用于本文所说的苏州城市。简言之 ,由于本文…     

An ethnoarchaeological inductive model for predicting archaeological site location: A case-study of pastoral settlement patterns in the Val di Fiemme and Val di Sole (Trentino,Italian Alps)

In this paper I propose a novel integration of inductive predictive modelling and ethnoarchaeology. The case study concerns seasonal upland pastoral settlement patterns in the eastern Italian Alps. A sample of modern pastoral sites has been selected, and their relationships with environmental variables have been analyzed in order to create a model to predict the location of archaeological upland pastoral sites. The model has been tested with modern and archaeological control samples. It has proved to be useful for predicting the location of specific site categories. Ethnoarchaeological fieldwork has been carried out in the same alpine sample area, which has enhanced the interpretative potential of the proposed model, suggesting that the spatial of the analyzed sites could well be related to their dairying function. The creation of ethnoarchaeological locational models with a predictive potential may be very important not only in helping to tackle some theoretical and methodological problems in predictive modelling, but also in enhancing the importance of ethnoarchaeology in landscape archaeology projects.
