Humans,climate or introduced rats – which is to blame for the woodland destruction on prehistoric Rapa Nui (Easter Island)?

When the first Polynesian settlers arrived on Rapa Nui, about 70% of the island was covered with dense woodland in which Jubaea palms dominated. Our investigations of extended soil profiles provide evidence that more than 16 million palm trees grew on the island. Nearly all palms were removed by the 16th century. Teeth marks on nutshells of the Jubaea palms from the 13th or 14th centuries attest to the activity of Pacific rats (Rattus exulans) on Rapa Nui, which were probably imported there by the first Polynesians settlers. Did the rats perhaps prevent the germination of palm seeds and thus the regeneration of the dense palm woodland of Rapa Nui?     

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.     

Ancient DNA of the Pacific rat (Rattus exulans) from Rapa Nui (Easter Island)

We report analysis of ancient mitochondrial DNA sequences from nine archaeological specimens (8 femura and 1 incissor) of Rattus exulans excavated from Anakena Beach Dune on Rapa Nui. Sequence of a 239-base-pair fragment of the hypervariable mitochondrial control region reveals a single mitochondrial DNA (mtDNA) sequence of all samples corresponding to the R9 haplotype prevalent in East Polynesia. This suggests a single or very limited introduction of Rattus exulans to the island. Rapa Nui, like other remote islands of Polynesia, remained effectively isolated following colonization.     

Stylistic variability of stemmed obsidian tools (mata’a), frequency seriation,and the scale of social interaction on Rapa Nui (Easter Island)

Easter Island, or Rapa Nui, has been the focus of much research and speculation, particularly with reference to the island’s hundreds of giant, enigmatic statues and the set of conditions that supported their construction and transportation. In this paper, we analyze an abundant class of lithic artifacts, mata’a, to study of patterns of cultural transmission with implications for the evolution of groups, competition, and scale of socio-political organization among this island population. While these kinds of studies often draw upon assemblages of decorated ceramics, here we show how analysis of variability unconstrained by performance allows us to measure aspects of inheritance related to the manufacture of these artifacts. In the case of mata’a from Rapa Nui, we demonstrate that it is possible to reach falsifiable conclusions about the evolutionary dynamics that shaped the remarkable archaeological record on Rapa Nui.     

Prehistoric settlement chronology on Rapa Nui,Chile: obsidian hydration dating using infrared photoacoustic spectroscopy

The prehistoric Polynesian inhabitants of Rapa Nui (Easter Island) utilized obsidian for nearly 700 years in many activities connected with daily life. The near ubiquitous occurrence of the natural glass in both domestic residences and religious structures makes the application of obsidian hydration dating highly suitable for the investigation of cultural change. We have applied previously developed calibrations that estimate hydration rates for obsidian based upon the structural water content of the glass as determined by infrared spectroscopy. The archaeological ages estimated by this method were compared with accelerator mass spectrometry (AMS) dates using short-lived woody species endemic to the island. The convergence between the two dating methods is strong and we suggest that obsidian hydration dating may be used on Rapa Nui to reliably date contexts where suitable material for AMS dating may not be available.     

East Polynesian Islands as Models of Cultural Divergence: The Case of Rapa Nui and Rapa Iti

The diverse island societies of East Polynesia are well-suited as models for comparative evolutionary analysis. Settled ca. 750 BP by a common ancestral population, colonists of the remote corners of the Pacific shared a pool of cultural traits that included commensal species, language, technology, and other cultural practices. Following colonization however, island populations diverged in language, subsistence practices, degree of territoriality, settlement patterns, investment and forms of monumental architecture, and social organization. Driven by historical circumstances and varied environmental conditions, this divergence presents evolutionary case studies of alternative paths of cultural change. One explanatory approach to this evolutionary divergence involves isolating the critical ecological parameters that likely constrained and shaped the diverse history of island populations. Here, we offer a comparative evolutionary analysis that explores the divergent histories of two marginal East Polynesian islands: Rapa Nui and Rapa Iti.     

A short note on banana (Musa) phytoliths in Lapita,immediately post-Lapita and modern period archaeological deposits from Vanuatu

We present results of phytolith analysis of deposits from three prehistoric settlement sites in Vanuatu: the small islands of Vao and Uripiv off the north east coast of the main island of Malekula and at Mafilau on the west coast of Epi Island. Samples from Vao Island coarsely encompass the period from Lapita times (c. 3000 BP) to the present. The data from this site suggest deforestation by people, with a decrease in palms and increase in grasses. The data from the three sites show evidence of an introduced cultigen during different prehistoric periods. Banana (Musa) phytoliths were found in one recent Vao layer (500 BP-present) and in Mafilau layers, the latter representing the immediate post-Lapita period (c. 2800–2500 BP). This phytolith type was also found at Uripiv in Lapita layers (c. 3000–2700 BP). Banana phytoliths are diagnostic so their presence in archaeological deposits in Remote Oceania, outside their natural distribution, provides secure evidence of cultivation. This demonstrates the potential of this line of evidence for identifying both the cultigens transported by early colonists and subsequent plant introductions. The data provide the first direct evidence of banana cultivation at a Lapita site in Remote Oceania and support the contention that horticulture was an integral part of the Lapita Cultural Complex.     

Island Biocultural Assemblages — The Case of Kinmen Island

ABSTRACT A growing mass of research contributes to our understanding of how biological and cultural diversity are related in complex and important ways. This paper presents an assembling process of biodiversity and cultural diversity on an island, Kin‐men (Quemoy), based on 1600 years of its environmental history. The study shows that the island's biocultural assemblages are a result both of external relations with the island's surrounding environment and internal relations within the island's changing human ecology. Distant political powers and economic forces are the two major external influences that have affected the flow of natural and cultural elements to and from the island, while ‘screening effects’ and ‘isolation effects’ are two factors that explain internal interactions. The island's biocultural assembling processes reveal that the openness of the island facilitates increase in the diversity of biocultural elements, while its less disturbed isolated condition fosters natural succession and co‐evolution. The study suggests that biocultural assemblages and the associated processes of co‐evolution and nature–society interactions are accomplished through the intermittent opportunities purposively provided by or inadvertently found in the openings and closures of boundaries, setting the scene for both boundary crossings and bounded shelter, by intent or chance.     

On the Additions to the Collection of National Antiquities in the British Museum

The evidence for prehistoric occupation in the area of the modern City of London is re-assessed. Two myths surrounding the city's prehistory are examined: a literary myth of a glorious Trojan past and a modern archaeological myth of the absence of prehistory. Having drawn a ‘traditional’ distribution map of prehistoric artefacts, the authors attempted to improve its reliability by quantifying the impact of Roman groundworks on the surviving prehistoric deposits. Topographic models of the area in prehistory and in the Roman period were drawn, and the methodology of the interpolation is discussed. The relative value of in situ, residual and stray finds are considered in the light of this new information. While there is good evidence for Late Bronze Age occupation in the City, the evidence for Neolithic activity is considered to be heavily skewed by Roman activity. The data are used to suggest areas of the City where there is particularly good potential for the survival of prehistoric deposits. The City provides a case study for analysing prehistoric material in a ‘difficult’, deeply stratified, urban context more associated with Roman and medieval archaeology.     

The interpretation of the earliest evidence of Lungfish ’Protopterus sp.’ in the Nile valley. El Zakiab Site,central Sudan

El Zakiab site yielded the earliest evidence of lungfish to be recorded from the excavated prehistoric settlements in the region of the Nile valley. The study of the osteological remains of the fish, its behaviour in the absence of water, and its ecological requirements offer evidence concerning the status of the site and its surroundings with reference to human seasonal adaptation.     

Clarifying prehistoric parasitism from a complementary morphological and molecular approach

This paper reports an approach to the identification of prehistoric parasitic infection, which integrates traditional morphological methods with molecular methods. The approach includes the strengths of each method while mitigating the limitations. Demonstrating the efficacy of this approach, we provide a case study from a 1400 year old desiccated fecal sample from La Cueva de los Muertos Chiquitos, archaeological site, near Rio Zape, Durango, Mexico. Traditionally prepared microscope slides were processed via microscopy and tentative ascarids were identified. Information regarding the parasites' developmental stage was recorded. DNA was then extracted directly from the slide material. From this DNA extract, a small segment of the 18S ribosomal RNA gene variant that is specific to Ascaris, and its phylogenetically close relatives, was targeted for PCR amplification and sequencing. Phylogenetic analysis of the DNA sequence best matched a member of physalopterids, rather than ascarids, with a single exception of a match to Contracaecum spiculigerum. Subsequent extractions, amplifications and sequencing of the original rehydrated coprolite material confirmed these results. The C. spiculigerum sequence represented a phylogenetic anomaly and subsequent analysis determined the sequence was an error in the BLAST database, likely attributable to misidentification of juvenile specimens prior to sequencing and submission. Physaloptera are a difficult genus to identify morphologically and can carry major health burdens. They may be underreported in humans, in part, because of morphological similarities to the more common human parasites belonging to ascarids. We conclude that integrating traditional morphological methods with molecular methods can help resolve this issue, in both contemporary and prehistoric populations.     

Focused,intense and long-term: evidence for granular ark (Anadara granosa) exploitation from late Holocene shell mounds of Blue Mud Bay,northern Australia

Explanatory frameworks relating to the appearance of shell mounds and the exploitation of molluscs (particularly the sand/mudflat bivalve Anadara granosa) during the late Holocene have tended to emphasise stasis and continuity. Very few analyses have adequately investigated the intensity of human predation during the mound period and the potential effects on the particular prey species. To this end, the biological and ecological characteristics of A. granosa, the dominant molluscan species for much of the known period of occupation in the region, are considered in detail, in combination with assessing the potential for human impact through predation via the measurement of 9106 A. granosa valves from three shell mounds. In explaining long-term economic change in this region of northern Australia, the focus has been placed on the analysis of relative changes and trends through time in prehistoric resource exploitation.     

Ecocriticism,Joyce, and the politics of trees in the ‘Cyclops’ episode of Ulysses

This article explores the ecological and ideological context of a passage in which two nationalists lament Ireland's treeless state. Although Joyce satirises these professed tree-lovers and the cause of reforestation, the passage alludes to a lively, serious topic in fin de siècle discourse. While Catholic nationalists blamed the loss of the island's once-vast, oak-dominated forests on British colonialism, a history elided by unionists, they shared a belief in the economic benefits of reforestation. Like Joyce, both sides knew little of Ireland's post-Ice Age natural history and did not appreciate the cultural importance of forest ecosystems to ancient Celtic peoples. Today, the Republic's profit-based plantations of conifers enact the materialist ideology of c.1904 reforestation advocates while overlooking the environmental and cultural benefits of restoring the biodiversity of native deciduous forests.     

SOUTHEAST ASIA'S FIRST ISOTOPICALLY DEFINED PREHISTORIC COPPER PRODUCTION SYSTEM: WHEN DID EXTRACTIVE METALLURGY BEGIN IN THE KHAO WONG PRACHAN VALLEY OF CENTRAL THAILAND?

Southeast Asian metallurgical developments have been a focus of international academic interest since Solheim (1968 ) and Bayard (1972 ) first published bronze artefacts in claimed early/middle third millennium bce contexts from northeastern Thailand, igniting a regional ‘origins’ of metallurgy debate that has smouldered for 40 years (e.g., White and Hamilton 2009 , Higham in press ). In this paper, we present the results of a lead isotope pilot study centred on the Khao Wong Prachan Valley of central Thailand—currently Southeast Asia's only documented prehistoric copper smelting locale. These preliminary data indicate that our ongoing regional metal exchange research programme may be able to elucidate interaction networks between copper‐producing and ‐consuming societies within and beyond Southeast Asia from c. 2000 bce to c. 500 ce . Furthermore, we are able to offer tentative evidence relevant to White and Hamilton's (2009 ) ‘Rapid Eurasian Technological Expansion Model’ for the Sino‐Siberian derivation of regional metal technologies around the turn of the third/second millennium bce .     

Early and mid Holocene tool-use and processing of taro (Colocasia esculenta), yam (Dioscorea sp.) and other plants at Kuk Swamp in the highlands of Papua New Guinea

Recent multidisciplinary investigations document an independent emergence of agriculture at Kuk Swamp in the highlands of Papua New Guinea. In this paper we report preliminary usewear analysis and details of prehistoric use of stone tools for processing starchy food and other plants at Kuk Swamp. Morphological diagnostics for starch granules are reported for two potentially significant economic species, taro (Colocasia esculenta) and yam (Dioscorea sp.), following comparisons between prehistoric and botanical reference specimens. Usewear and residue analyses of starch granules indicate that both these species were processed on the wetland margin during the early and mid Holocene. We argue that processing of taro and yam commences by at least 10,200 calibrated years before present (cal BP), although the taro and yam starch granules do not permit us to distinguish between wild or cultivated forms. From at least 6950 to 6440 cal BP the processing of taro, yam and other plants indicates that they are likely to have been integrated into cultivation practices on the wetland edge.     

Introduced taro (Colocasia esculenta) and yams (Dioscorea spp.) in Podtanean (2700–1800 years BP) deposits from Mé Auré Cave (WMD007), Moindou,New Caledonia

Plant microfossil analysis was carried out on deposits bearing Podtanean (2700–1800 years BP) ceramics from Mé Auré Cave, Moindou, New Caledonia. Starch residues of introduced Colocasia esculenta, Dioscorea esculenta and one or more, undifferentiated Dioscorea species were identified. The latter include Dioscorea alata, D. bulbifera, D. nummularia and D. pentaphylla. The data provide the first direct evidence of prehistoric horticulture in New Caledonia.     

The Strategic Importance of Cyprus and the Prospect of Union with Greece, 1919–1931: The Greek Perspective

The outbreak of the First World War brought about an important change in the status of Cyprus which was officially annexed by Great Britain. In the years that followed, successive Greek governments preferred not to pose openly the prospect of the island's cession to Greece. Athens understood that, given London's strategic interest in Cyprus, a favourable solution of the issue was inevitably related with the satisfaction of British strategic interests in the wider Eastern Mediterranean region. In other words, the prospect of the creation of British military bases on Cyprus in the event that London actually consented to the island's union with Greece was not rejected on the part of Athens; on the contrary, it was seen as a necessary sacrifice in order to serve the final goal of Enosis.     

Gendering the Black Death: Women in Later Medieval England

This review article of Mavis Mate's Daughters, Wives and Widows after the Black Death: Women in Sussex, 1350–1535 (1998) locates Mate's work within the broader context of the debate about changes in women's social position caused by the collapse in population following the Black Death. Was demographic decline accompanied by growing social and economic opportunities for women or should historians emphasise the continuity of female work as low‐skilled, low‐status and low‐paid throughout the late medieval and early modern periods? How did women's role in the labour market affect the age of marriage, fertility rates and long‐term population change? In general, Mate's conclusions offer support to the ‘pessimists’: women's work was vital to the household but economic centrality did not bring a commensurate social power or legal rights and the ideology of female subordination remained firmly in place. The main problem with Mate's case is, inevitably, a lack of evidence, for family structure, for the sexual division of labour and, above all, for affective relations. Nevertheless, this detailed, empirically based local study shows how successfully women's history has moved into the historical mainstream.
