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.     

Fish as diet resource in North Spain during the Upper Paleolithic

During the last glacial maximum, the west European modern humans adapted to adverse conditions and their populations subsisted exploiting the natural resources available. Fish were always present as a source of animal protein, although their importance in the human diet and their contribution to the expansion of humans has not been fully explored. Based on the compilation of zooarchaeological evidences from north Spanish sites we have discovered a constant pattern of exploitation of freshwater fish (Salmonids) with high incidence in the human diet during the Upper Paleolithic. Shifts in the exploitation of marine resources can be explained by climate-related geographical changes. The characteristics of salmonids that make them target species for supporting human survival in adverse climate periods are identified and discussed.     

Marine resource intensification in Viking Age Europe: the molluscan evidence from Quoygrew,Orkney

This paper addresses whether molluscan evidence from Orkney can shed light on the hypothesis that there was a trend towards the intensification of marine resource use at the end of the first millennium AD. The stratified middens of Quoygrew, which date from approximately the 10th to the 13th centuries, are shown to contain predominantly limpets, which may have been used for baiting fish. From metrical data it is shown that these limpets reduce in size through time. In order to test whether this observation is related to intensification in exploitation, analysis of limpet shoreline location was carried out. In addition, age data were used to demonstrate a lowering of average age which suggests intensification in gathering rather than environmental influences, particularly during the 11th–12th centuries at this site.     

10,000 years of human predation and size changes in the owl limpet (Lottia gigantea) on San Miguel Island,California

To investigate potential human impacts on California Channel Island shellfish stocks over the past 10,000 years, we measured 1718 owl limpet shells from 19 archaeological components on San Miguel Island. Inhabiting the middle intertidal zone of Pacific Coast rocky shores, owl limpets are slow-growing mollusks that can live for 30 years and reach lengths of over 100 mm. Recent ecological studies indicate that owl limpets are highly susceptible to heavy human predation, which results in reduced mean shell sizes among Lottia populations along the coasts of Alta and Baja California. On San Miguel Island, we identified a significant trans-Holocene reduction in mean owl limpet size, beginning more than 6500 years ago and accelerating at least 4400 years ago. Fluctuations in limpet size show no clear correlation with changes in sea surface temperature and marine productivity, suggesting that increased predation by growing human populations was primarily responsible for the reduction in Lottia size over time. Our results provide further evidence that prehistoric peoples significantly influenced nearshore fisheries long before the development of the commercial and industrialized fisheries of historic times.     

The Scandinavian reindeer (Rangifer tarandus L.) after the last glacial maximum: time,seasonality and human exploitation

Antlers and bones of reindeer (Rangifer tarandus L.) are the most frequently found vertebrate remains from the Late Glacial deposits of Southern Scandinavia. The Danish collection now consists of more than 350 specimens and of these 47 have been radiocarbon dated extending the range of occurrence in the area with ca. 1300 ¹⁴C yr. Thus the first occurrence is pushed back to ca. 12?500 ¹⁴C yr BP (late Bølling chronozone) while the youngest date lies at ca. 9200 ¹⁴C yr BP (late Preboreal chronozone) establishing that the reindeer survives well into the Holocene. The seasonal dates of the reindeer indicate for the first human occupation (the Havelte group from the Bølling period) a summer, autumn and early winter occupation, with reindeer, as well as man, apparently being absent during the coldest winter months. Finally, it is shown that Southern Scandinavia acted as a calving area throughout the Late Glacial and Early Holocene thus discrediting the North–South model of reindeer groups moving from a wintering area in Southern Scandinavia to a calving area in the foothills of the North European plain.     

Late Holocene economic specialisation through aquatic resource exploitation at Kobadi in the Méma,Mali

Following the last humid phase of the Late Holocene, human groups left the Saharan latitudes of northern Mali at around 2500 cal. years BC to settle further south. The Kobadi population was among the first Neolithic human groups to enter the Niger Inland Delta in central Mali. People adapted to their new environment by intensifying one of their former subsistence practices, namely fishing. The rich and diversified ichthyofauna exploited was dominated by large Nile perches and a variety of catfish taxa. It testifies to relatively stable hydrological conditions: a fluvial lake which was probably linked permanently to the main Niger River. Fish were caught with harpoons and probably also with diverse fishing devices such as nets, baskets and fences. Preparation processes prior to cooking cannot be determined, but fish were probably cooked on hot coals or stones, the left‐overs of the meals being discarded randomly at the site. Intense exploitation of the aquatic environment near Kobadi provided an abundant, secure and predictable source of protein. Besides fish and riparian mammals, reptiles such as turtles, monitors and crocodile were hunted. Domestic cattle provided milk and/or meat. These animals were either raised at the site or obtained by means of exchange with pastoral groups roaming the hinterlands. From the 2^nd millennium BC, the focus on aquatic resources at Kobadi, mostly through the intensification of fish exploitation, may demonstrate the beginning of economic specialisation in the Niger Inland Delta.

Distribution parameters of guanaco (Lama guanicoe), pampas deer (Ozotoceros bezoarticus) and marsh deer (Blastocerus dichotomus) in Central Argentina: Archaeological and paleoenvironmental implications

In this paper we use non-ambiguous collections and sightings data from the 18th century to generate potential distribution models of three species of South American ungulates. These ungulates (Lama guanicoe -guanaco-; Ozotoceras bezoarticus -pampas deer- and Blastoceros dichotomus -marsh deer-) have different and specific environmental requirements. Through MaxEnt software, twenty-two environmental variables that characterize the distribution area of each species are defined. Once the models are generated, they are compared with the faunal associations found at Late Holocene archaelogical sites in order to infer paleoenvironmental conditions. We also discuss the role played by humans in the faunal associations which are "anomalous" or inconsistent with those models, like the spatial overlap of guanaco and marsh deer.     

The Seaweed FlyThoracochaeta zosterae(Hal.) (Diptera: Sphaerocidae) in Inland Archaeological Contexts: δC and δN Solves the Puzzle

The presence of the flyThoracochaeta zosteraein cesspits had led to the unlikely interpretation that seaweed had been present in Mediaeval cesspitis. Archaeological and modern pupae fromT. zosteraewere sampled along with their probable larval diets (extracted plant material from cesspit and seaweed, respectively). The spacing between pupae and food for δ¹³C and δ¹⁵N was similar for both modern and archaeological samples. Modern pupae had isotopic ratios typical for marine invertebrates for δ¹³C. Archaeological puparia had isotopic values typical for terrestrial grazers (i.e., non-marine), indicating that there was no marine inclusion in the cesspits.     

Archaeological and archaeomagnetic dating at a site from the ager Tarraconensis (Tarragona,Spain): El Vila-sec Roman pottery

A very accurate archaeological dating of a Roman site in NE Spain (El Vila-sec) was made based on the typology of pottery artifacts. Three different phases were identified with activity ranging from the mid-1st century BC to the early-3rd century AD. Analyses of bricks from kilns at El Vila-sec produced data on their stored archaeomagnetic vector. These data were compared with the secular variation curve for the Iberian Peninsula and the SCHA.DIF.3K regional archaeomagnetic model. Both, the reference curve and the model, produced probability distributions for the final period of use for two kilns from the second archaeological phase that were not used during the third phase. At a 95% confidence level, both time distributions cover a wide chronological range including the presumed archaeological age. Both the Iberian secular variation curve and the SCHA.DIF.3K regional model proved to be suitable models for dating the site, although on their own they do not produce a single unambiguous solution. This archaeomagnetic approach could also be applied to neighbouring archaeological sites that have an imprecise archaeological age.     

Late Holocene human impact on the vegetation around Mizorogaike Pond in northern Kyoto Basin,Japan: a comparison of pollen and charcoal records with archaeological and historical data

Pollen and macroscopic charcoal analyses of AMS radiocarbon-dated sediment from Mizorogaike Pond, located near Japan’s ancient capital established in AD 794, were used along with archaeological and historical data to reconstruct vegetation change in the northern Kyoto Basin since 7300 cal yr B.P. Between ca. 7300 and 3400 cal yr B.P. (Early to Late Jomon period), the site was surrounded by warm-temperate forest composed of Quercus subgenus Lepidobalanus and Q. subgenus Cyclobalanopsis with Celtis/Aphananthe trees. With the occurrence of fire disturbance, Q. subgenus Lepidobalanus increased from ca. 3400 to 1400 cal yr B.P. (Late Jomon to Kofun periods). In the early seventh century (Asuka period), Pinus started to increase, coinciding with a significant charcoal peak, probably related to the operation of roof tile kilns near the site. Pinus continued to increase and Q. subgenus Cyclobalanopsis decreased through the seventh to tenth centuries (Asuka to Heian periods). Further increase of Pinus occurred in the eleventh century, possibly reflecting the establishment of the manor of Kamigamo Shrine. From the eleventh to seventeenth centuries (Heian to medieval periods), no significant vegetational change or fire disturbance took place. In the eighteenth century, the landscape became totally open, with poor vegetation and sparse Pinus woodland. The medieval and early modern landscapes reconstructed from the palaeoecological record are rather similar to those described from studies of ancient artwork and historical documents. This study demonstrates that late Holocene vegetation change in the northern Kyoto Basin was closely tied to anthropogenic activities, such as the pottery industry and fuel wood collection.     

Pollen analysis of core DS7-1SC (Dead Sea) showing intertwined effects of climatic change and human activities in the Late Holocene

The Dead Sea sediment holds the archives of a complex relationship between ever-changing nature and ancient civilisations. Here the detailed pollen analyses of core DS7-1SC (off-Ein-Gedi) are presented for the first time. The record covers the last 2500 years. The facies changes from halite (when no freshwater flows in the Dead Sea) to laminites (when rainfall provides sufficient inflow for the Jordan and subsidiary rivers) a couple of times through the record. The pollen diagram (supported by the facies change) shows a wetter Roman-Byzantine period, which allowed intensive arboriculture and a wetter period at the end of the XIXth and beginning of the XXth centuries, the latter in good relation with historical and instrumental data. Based on radiocarbon chronologies on several pollen diagrams along the western Dead Sea shore, the transition to drier climates and the transition to pastoralism are suggested to take place between a few decades before the Islamic period and close to this transition.     

Past and present marine mammal hunting rates and abundances: dugong (Dugong dugon) evidence from Dabangai Bone Mound,Torres Strait

Dugongs (Dugong dugon) are a key food item and a totemic animal with major spiritual significance for Torres Strait Islanders of northeastern Australia. These marine mammals are officially classed vulnerable to extinction which has placed hunters under considerable internal (cultural) and external (bureaucratic) pressure to lower hunting rates dramatically to sustainable levels. But did Torres Strait Islanders hunt dugongs at much lower rates in the pre-colonial past? Excavation of a ritual dugong bone mound on Mabuyag island revealed the remains of 10,000–11,000 dugongs hunted between c. 1600 and c. 1900AD. The translated hunting rate of 33–37 dugongs per year is surprisingly high and challenging as this single site represents one-third of what conservation biologists argue is the current mean sustainable hunting rate for the entire Torres Strait archipelago. These data suggest that dugong abundance was much higher in the pre-colonial past and that current hunting rates are uncharacteristically unsustainable primarily due to an unprecedented dugong population crash and not increased post-contact hunting rates.     

Editorial: Anatomy of a publication. the Journal of Archaeological Science, the first nine years

The structure of this journal during the first 9 years of its publication is examined. Sub-disciplinary composition indicates a predominance of zoological, botanical and materials papers. Scientific approach is difficult to evaluate but is predominantly inductive. Contributions from the U.K. exceed those from other countries, though articles from elsewhere, especially the U.S.A., have increased through time. The location of research sites shows a similar distribution. Multiple authorship is shown to be high in comparison with some sciences. Articles have become longer and fewer during the life of the journal. Discussion is directed towards the requirements of the journal readership.     

Environmental changes in the Maryut lagoon (northwestern Nile delta) during the last ∼2000 years

Here, we interpret the evolution of Maryut lagoon (Egypt) during the past ∼2000 years. Chronostratigraphy and laboratory analyses have enabled us to identify four main phases since the 3rd century AD: (1) a fluvial-dominated lagoon between the 2nd–3rd and the 8–9th centuries cal. AD; (2) a gradual desiccation of the lagoon toward a sebkha-like environment from the 9–10th to the 13th centuries cal. AD; (3) a fluvial-dominated lagoon from the 13th century cal. AD; and (4) a second gradual desiccation between the 17th and the 18th centuries cal. AD. The general aridification trend described throughout the study period may be linked to the gradual decline of the Canopic branch, which supplied the Maryut lagoon with freshwater. Nonetheless, at shorter timescales, the different phases of lagoon aridification and flooding coincide with land abandonment and irrigation works in the region. It is suggested that the history of the Alexandria countryside has been a key driver in shaping the environmental history of the Maryut during the past ∼2000 years.     

Managing the Archaeological Heritage: The Case of Akrotiri,Thera (Santorini)

Abstract

This article deals with the archaeological site of Akrotiri on the Cycladic island of Thera (Santorini), Greece, and demonstrates, in particular, how the construction of a new protective shelter has provided an opportunity for enhancing the present and future conservation and management of the site in accordance with, among other values, the aspirations of the local community. Drawing on the experience of the author as Director of the excavation, special emphasis will be placed on the features of the new bioclimatic shelter that can accommodate the continuous use of the site as both a scientific workshop and a tourist attraction.

Sweet potato (Ipomoea batatas) and banana (Musa sp.) microfossils in deposits from the Kona Field System,Island of Hawaii

Analysis of plant microfossils (pollen, phytoliths, starch grains and xylem cells) was carried out on 12 soil samples from a variety of pre-contact archaeological features in South Kona within a portion of what has been termed the Kona Field System, on the Island of Hawaii. The oldest radiocarbon ages of the sampled deposits are 1300–1625 AD and 1310–1470 AD. The pollen and phytolith evidence suggests a change from more to less trees and shrubs in the area as a result of human activity. We found phytoliths of banana (Musa sp.) leaves in most and starch grains and xylem cells of tuberous roots of c.f. sweet potato (Ipomoea batatas) in all of the samples, suggesting that the sampled features were associated with these crops and that both crops were cultivated intensively within the study area. Higher concentrations (volumetric) of starch and xylem in samples from older deposits suggest that cultivation was more intensive then. The apparent absence of starch and xylem remains of other tuberous crops archaeologically identified elsewhere in Polynesia suggests that tuberous cropping within the study area was mono-specific.
