Prehistoric seal carcass exploitation at the Shag Mouth site,New Zealand

Seal populations in New Zealand declined dramatically during the prehistoric period. The loss of this important resource significantly affected the foraging practices at the Shag River Mouth site. Previous research documented substantial changes to the diet with the decline of seals and the corresponding decline in foraging efficiency. In this study, I examine how New Zealand foragers altered their use of seal carcasses as the availability of these marine mammals declined. Otariid seal data from the Shag River Mouth site in southern New Zealand are analyzed to test changes in butchery/transport and skeletal element breakage patterns expected with resource depression and declining foraging efficiency. This research shows that at Shag Mouth, seal carcasses were used more intensively over time. However, bone breakage patterns showed little change in the exploitation of within-bone nutrients.     

Molluscan foraging efficiency and patterns of mobility amongst foraging agriculturalists: a case study from northern New Zealand

A New Zealand example illustrates the potential of foraging efficiency (FE) measures to inform not only on human-prey dynamics, but also to help identify situations where mobility is constrained or stimulated. Marked declines in Māori molluscan FE, coupled with increased shellfish usage, are identified over a ca. 450-year period at the coastal locality of Harataonga Beach, New Zealand. The potential effects of climate change are considered using newly available southwest Pacific multi-proxy records and temperature sensitive species, but correlations are lacking. The molluscan results signal possible restrictions on logistic and/or residential mobility in late prehistory, while evidence from the broader cultural landscape points to increasing agricultural investments and marked social competition. The Ideal Free Distribution model (IFD) is used to consider regional-scale interactions between foraging efficiency, agricultural developments, and competition, and their effects on mobility. Geographic and temporal variation in the patterning and causes of population movements is highlighted through this model, particularly differences between large game foragers in the south and populations with mixed economies in the north. In late prehistory, many northern areas including Harataonga apparently experienced reductions in the geographic scale of population movements, coupled with intensified intra-territorial mobility. The latter was an outcome of labour being widely dispatched across tribal territories, quasi-specialisation in subsistence tasks, and pooling and exchange of resources through a variety of social mechanisms which often involved population movements.     

The Broad Spectrum Revolution at 40: Resource diversity,intensification, and an alternative to optimal foraging explanations

More than 40 years ago Kent Flannery coined the term Broad Spectrum Revolution (BSR) in reference to a broadening of the subsistence base of Late Pleistocene hunter–gatherers in the Near East that preceded and helped pave the way for the domestication and plants and animals and the emergence of agriculture. Set within a demographic density model that projected differential rates of population growth and emigration in different resource zones of the Near East, Flannery’s BSR quickly became a global construct linking resource diversification and intensification to imbalances between population and environmental carrying capacity. In recent years the BSR has proven especially attractive to researchers working within an optimal foraging theory (OFT) framework in which diversification and intensification of subsistence only occurs within the context of resource depression, caused by either demographic pressure or environmental deterioration. This OFT perspective, that situates human societies in a one-way adaptive framework as they are forced to adapt to declining availability of optimal resources, however, is increasingly being called into question. Numerous examples of diversification and intensification are being documented in contexts of resource abundance shaped, in part, by deliberate human efforts at ecosystem engineering intended to promote resource productivity. An alternative approach, framed within a newer paradigm from evolutionary biology, niche construction theory (NCT), provides a more powerful explanatory framework for the BSR wherever it occurred.     

Declining foraging efficiency and moa carcass exploitation in southern New Zealand

The application of foraging theory to understanding carcass exploitation is a relatively recent development. The methodology developed by archaeological and ethnoarchaeological research on butchery/transport studies has been integrated into a behavioral ecological framework to create models that can be used to understand archaeological carcass exploitation. In this paper, I use such a model to examine how New Zealand foragers altered their use of moa carcasses as the availability of these large birds declined. Moa data from the Shag River Mouth site in southern New Zealand are analyzed to test changes in butchery/transport and skeletal element breakage patterns expected with resource depression and declining foraging efficiency. This research shows that at Shag Mouth, field processing of moas increased and marrow, and possibly grease extraction intensified over time.     

Christianity,Gender, and the Working Class in Southern Dunedin, 1880–19401

This article is a study of the southern suburbs of Dunedin, which during the late nineteenth century became the most industrialized and working class urban area of New Zealand. Analyzing the social composition of fifteen southern Dunedin churches, I question the idea, widely held by New Zealand historians, that the working classes had largely turned their backs on organized religion. In keeping with recent scholarship in the social history of British and Irish religion, I show that unskilled workers were better represented in many southern Dunedin congregations that previous historians have acknowledged and that skilled workers numerically dominated most churches. When women are included in the analysis, working class predominance increases further. Signing the suffrage petition in remarkable proportions, working class Christian women turned the southern suburbs into a world‐leading first wave feminist community. Moreover, varieties of popular Christianity flourished beyond the ranks of active churchgoers. I conclude by suggesting that New Zealand historians need to rethink the old “lapsed masses” and “secular New Zealand” assumptions and to investigate the diverse varieties of Christianity shaping the culture, and their sometimes conflicting this‐worldly meanings.     

Identifying palaeo-environments and changes in Aboriginal subsistence from dual-patterned faunal assemblages,south-western Australia

Palaeo-environments and past human subsistence patterns are difficult to determine from dual-patterned faunal assemblages where human and non-human predators have accumulated and intensively modified animal bones. This paper examines such records in the Leeuwin–Naturaliste Region of south-western Australia, where a thin belt of coastal limestone contains caves and rock shelters with rich faunal deposits. The Late Pleistocene and Holocene part of this record derives from four archaeological sites: Devil's Lair, Tunnel Cave, Witchcliffe Rock Shelter and Rainbow Cave. Correspondence analysis combined with cluster analysis enables a preliminary assessment of habitat changes using simple species abundances in the faunal assemblages and comparison with indices of past human activity in the sites and the species’ present habitat preferences. These inferred changes, consistent with previous analyses of faunal remains and tree charcoal, suggest that late Holocene sites document Aboriginal occupation in coastal heath, scrub and woodland. Late Pleistocene deposits record hinterland occupation at times of low sea-level when the coast was up to 30 km seawards of its present position and the surrounding vegetation was open-forest or woodland. As rainfall increased and vegetation changed in the Holocene, species foraging in open-woodland declined or became locally extinct, while species requiring closed canopy habitats increased. Rank-order correlations of taxa and archaeological remains from depositional sequences before and after the environmental change indicate that the occupiers of late Holocene sites favoured the same generalist species that occupiers of Late Pleistocene sites had favoured, which were available at all times. Prey habitats, foraging behaviours and historic records of ethnographic hunting and settlement pattern suggest that this local continuity is consistent with maintenance of a “dispersive mode” subsistence pattern in the region.

Holocene artiodactyl population histories and large game hunting in the Wyoming Basin,USA

Regional paleoenvironmental reconstructions and data on artiodactyl response to climate change suggest that large game densities would have expanded during the late Holocene in the Wyoming Basin. Within this context, we use the prey model of foraging theory to predict a late Holocene increase in the hunting of artiodactyls, relative to lagomorphs and rodents. This prediction is then tested against 144 dated components documenting human subsistence in the Wyoming Basin. Close fits are found between the deductively derived prediction and the empirical records: significant increases in artiodactyl hunting occurred during the late Holocene. These results have implications for the interpretation of long-term increases in large-game in Holocene archaeofaunas throughout North America.     

δ18O Analyses of the Humpbacked Conch (Gibberulus gibberulus): Evaluating a Proxy for Reconstructing Sea-Surface Temperature at Chelechol ra Orrak,Palau

ABSTRACT

In Palau, Micronesia, marine resources, particularly shellfish, played a vital role in human subsistence for millennia. Despite the vast array of molluscan species in archaeological assemblages, there is a dearth of data on nearshore palaeoecology or prehistoric shellfish foraging practices. In this study, we analysed stable oxygen isotopes (δ¹⁸O) values present in the calcium carbonate shell of Gibberulus gibberulus from the Chelechol ra Orrak archaeological site to reconstruct average nearshore sea-surface temperatures (SST) from approximately 1500–1100 cal BP. Modern shellfish samples and environmental data were collected from intertidal zones near the site and x-ray diffraction (XRD) was employed to identify the biomineralogical composition of G. gibberulus. These steps provide necessary information for the selection of the proper oxygen isotope-to-SST conversion formula. The selected formula was applied to δ¹⁸O samples from archaeological shells to reconstruct prehistoric SST averages. The results of this proxy validation study verify that G. gibberulus accurately records ambient SST and can be used to reconstruct ancient nearshore conditions. These findings also contribute to the establishment of an environmental baseline, which can be used to examine how environmental changes may have influenced the availability of molluscan taxa that in turn influenced human subsistence practices through time.     

Neolithic subsistence patterns in northern Borneo reconstructed with stable carbon isotopes of enamel

The Neolithic period in island Southeast Asia is characterized by various population movements, technological innovations, and the introduction/adoption of agricultural foodstuffs. Human subsistence trends during this period, however, are poorly understood. Broad spectrum foraging is generally assumed for prehistoric groups utilizing rain forest food resources but the degree to which cultigens were part of the dietary repertoire remains unclear. This paper explores human subsistence patterns at three penecontemporaneous Neolithic sites in Sarawak (East Malaysia) using stable isotope ratios of carbon and oxygen derived from tooth enamel apatite. The sites (Niah Cave, Lubang Angin, and Gua Sireh) differ in local ecology and cultural circumstance but all are situated in C₃-dominant lowland primary rain forest. Significant differences in δ¹³C values between sites likely reflect the canopy effect and variations in foraging pattern. Lower values at Lubang Angin suggest dependence upon closed forest foraging. Higher values at Neolithic Niah Cave and Gua Sireh suggest more open forest horticulture and subsistence, including some form of systematic food production, collection, and/or habitat modification.     

Subsistence continuity,change, and environmental adaptation at the site of Nugljanska,Istria, Croatia

This paper investigates changes in subsistence strategies at the upland cave site of Nugljanska (Croatia) at the end of the last ice age, during a time of rapid sea level rise and changing environment. We analysed the faunal assemblage from archaeological levels spanning the Pleistocene–Holocene transition (15,000–8000 years BP) and evaluated changes in relative abundance of species, measured species diversity, and compared the representation of terrestrial mammal and marine resources. We found a significant shift in the most abundant prey species exploited (from red deer, Cervus, to wild boar, Sus). There was some correlation between dietary diversification and periods of increased moisture availability and the spread of deciduous forest in the area. Our results suggest that there was a continuing reliance on terrestrial resources throughout time and that changes in dietary patterns were likely due to local environmental change and potentially, changing seasonal mobility strategies, at the Pleistocene–Holocene transition.     

Hunter–gatherer foraging ranges, migrations, and travel in the middle Holocene Baikal region of Siberia: Insights from carbon and nitrogen stable isotope signatures

Foraging ranges, migrations, and travel among Middle Holocene hunter–gatherers in the Baikal region of Siberia are examined based on carbon and nitrogen stable isotope signatures obtained from 350 human and 203 faunal bone samples. The human materials represent Early Neolithic (8000–6800 cal BP), Late Neolithic (6000–5000 cal BP), and Early Bronze Age periods (∼5000–4000 cal BP) and come from the following four smaller areas of the broader region: the Angara and upper Lena valleys, Little Sea of Baikal’s northwest coast, and southwest Baikal. Forager diets from each area occupy their own distinct position within the stable isotope spectrum. This suggests that foraging ranges were not as large as expected given the distances involved and the lack of geographic obstacles between the micro-regions. All examined individuals followed a similar subsistence strategy: harvesting game and local fishes, and on Lake Baikal also the seal, and to a more limited extent, plant foods. Although well established in their home areas, exchange networks with the other micro-regions appear asymmetrical both in time and direction: more travel and contacts between some micro-regions and less between others. The Angara valley seems to be the only area with the possibility of a temporal change in the foraging strategy from more fishing during the Early Neolithic to more ungulate hunting during the Late Neolithic–Early Bronze Age. However, the shift in stable isotope values suggesting this change can be viewed also as evidence of climate change affecting primary productivity of the Baikal–Angara freshwater system.     

Farming and/or foraging? New environmental data to the life and economic transformation of Late Neolithic tell communities (Tisza Culture) in SE Hungary

The turn of the 6th and 5th millennia BC witnessed probably the largest economic and cultural transformation of SE Europe giving rise to a new techno-complex occupying the alluvial plains of the Tisza River and its tributaries in the southern parts of the Carpathian Basin. Representatives of the Tisza Culture were engaged in intensive farming complemented with foraging creating a complex system of hierarchical multi-layered settlements (tells). The favorable endowments of the sites with a large variety of multiple ecotones ideal for multifocal subsistence, as well as the introduction of new farming techniques ensured the establishment of long-term sedentary lifeways. However, according to the archeology, a major shift in subsistence happened toward the end of the Late Neolithic marking the terminal part of the evolution of the culture. Traditional crop cultivation was increasingly complemented with hunting, animal husbandry gaining importance. Other second-line resources like fish and shellfish followed the same pattern. Finally, tells were disintegrated and a new cultural group of the Copper Age emerged. The exact background of these transformations is still unknown. In order to see whether or not potential transformations in the local riparian environment had some role in shaping human behavior, a multiproxy paleoecological analysis was implemented on mollusk material of one of the largest tell sites of SE Hungary. Freshwater mollusks collected by humans in themselves characterize the quality of the water body from which they derive. They are also an excellent marker of socioeconomic response to environmental stress. According to our findings the emergence of new settlement phases and the intensified foraging could have been correlated with alteration of stream properties yielding successively higher floods. This was initially beneficial creating lush pasturelands for large bodied prey infiltrating the area during the referred period like aurochs, red-deer. But ultimately it might have reduced areas suitable for agriculture and living most likely leading to social disruption besides other cultural, social processes.     

Ancient Maya wood selection and forest exploitation: a view from the Paynes Creek salt works,Belize

Ancient building construction wood preserved in a peat bog below the seafloor in a shallow mangrove lagoon in Paynes Creek National Park, Belize, provides an exceptional record of Classic Maya wood use. Identifications of construction wood at Early Classic Chan B'i, and Late Classic Atz'aam Na, are reported and discussed to assess forest exploitation and species selection over time. Black mangrove (Avicennia germinans) dominates the Early Classic assemblage. The Late Classic assemblage is characterized by greater variability and an absence of mangrove species. When considered in the environmental context, identified species conform to principles of optimal foraging. The change in the wood assemblage over time suggests overexploitation of forest resources, resulting in deforestation of the local landscape and subsequent adaptation of foraging behavior. Deforestation is linked to the wider social context in which growing inland populations created demand for salt, putting greater pressure on the forest resources exploited by the Paynes Creek salt works for fuel and timber.     

Prehistoric Fijian diet and subsistence: integration of faunal, ethnographic, and stable isotopic evidence from the Lau Island Group

We explore subsistence practices and dietary change on islands in the central Lau Group of Fiji with zooarchaeological methods and stable isotopic analysis of human and animal skeletal material interpreted through an ethnoarchaeological lens. Our dataset combines detailed identifications of fauna, especially fishes, with stable isotopic (δ¹³C, δ¹⁵N) values of human and animal bone collagen and apatite carbonate spanning approximately three thousand years of human occupation on three study islands. Additionally, over fifty inshore and offshore contemporary fishing expeditions were observed on all study islands over a six-year period. We integrate these separate lines of evidence to form robust interpretations of Lauan subsistence patterns over a broad temporal scale. We add to the existing literature on stable isotopic analysis of archaeological bone from Remote Oceania and compare all of these groups through time. Our results indicate that Lauans differentially relied on nearshore reef resources rather than pelagic fishes, and terrestrial endemic species may have served as a portion of the diet during the early prehistoric period. Root crops (e.g., taro, yam) provided the majority of calories to the diet; however, sea grapes likely contributed to the early diet. Our isotopic results differ from previous studies of Fijian diet and that of Remote Oceania at a time of probable marine ecosystem shifts (AD 1300) illustrating diet breadth and variability in subsistence strategies potentially due to climatically influenced resource depletion.     

Modelling the Neolithic transition in a heterogeneous environment

The Neolithic transition, involving the change of subsistence from foraging to agriculture, can fruitfully be modelled mathematically, as, e.g., in the three-population model of Aoki et al. (1996). Here that model is modified to include some features of population dynamics in a realistic, two-dimensional environment, and including population pressure, competition for resources between farmers and foragers, and the dependence of the population carrying capacities and diffusivities on the environmental conditions. This modified model allows for the survival of foragers in regions where environmental conditions do not favour farming. The model is tentatively applied to the Indian subcontinent, which is a complicated example of this transition involving multiple domestication centres. The results are briefly compared with published archaeological data.     

Reconstructing prehistoric hunter–gatherer foraging radii: a case study from California's southern Sierra Nevada

The concept of the foraging radius is essential to understanding hunter–gatherer settlement, subsistence, and sociocultural complexity yet is notoriously difficult to reconstruct archaeologically. Late prehistoric Western Mono foraging radii in the southern Sierra Nevada were reconstructed using GIS analysis of least-cost path distances between dispersed caching features and centralized residential features. Mean distances from settlements to caches exhibit a bimodal distribution, with peaks between 0.5 and 5.0 km, and 6.0 and 8.5 km, the former representing a caching limit and the latter a foraging limit around major settlements. Combined, these data demarcate a two-part foraging radius predicated not only on sustaining winter group aggregations but also on facilitating spring and summer residential moves. These results show the efficacy of using features and simple GIS-based spatial analyses to reconstruct prehistoric foraging radii and provide the means to model the energetics of different foraging behaviors, these speaking strongly to the social and economic factors conditioning the development of complex hunter–gatherer societies.     

Late Pleistocene marine birds from southern Peru: distinguishing human capture from El Niño-induced windfall

The Central Andean hyperarid littoral has abundant marine fauna that would have been attractive to the earliest inhabitants. Whether people hunted or scavenged marine animals during the terminal Late Pleistocene have social and technological implications for understanding ancient Andean foraging. The periodic phenomenon of El Niño/Southern Oscillation (ENSO) disrupts marine food chains and results in the death of significant numbers of marine vertebrates and microorganisms. The onset of ancient El Niño events may have created a subsistence opportunity for human coastal inhabitants along the Pacific coast of the Central Andes when large numbers of guano-producing birds (cormorants, boobies, and pelicans) became weak and eventually died. The remains of numerous marine birds dominate the Late Pleistocene archaeological site of Quebrada Tacahuay in far southern Peru. This Terminal Pleistocene occupation dating to 10,770–10,290 years ago (uncalibrated radiocarbon years; 12,880–11,970 calendar years ago) was buried and sealed by an apparent ancient El Niño-induced debris flow. Using characteristics of the faunal assemblage I assess whether people hunted marine birds or ENSO created a subsistence opportunity for people to either scavenge a catastrophic assemblage or collect a community of vulnerable birds prior to the debris flow. I present avian skeletal part frequencies, butchering patterns, and the quantities and variety of marine bony fishes. An analysis of vertebrate taxonomic and skeletal composition in conjunction with an analysis of site context does not support the hypothesis that paleoenvironmental conditions generated an opportunity for the facile collection of either dead or weak birds. In contrast, the faunal data suggest that humans actively hunted, captured, and consumed healthy marine birds. When evaluating the possible role of environmental fluctuations on human behavior and diet, researchers must consider not only the taphonomy of the most abundant remains, but also how other vertebrate taxa in a region are affected as well as the archaeological context.     

Measuring Foraging Efficiency with Archaeological Faunas: The Relationship Between Relative Abundance Indices and Foraging Returns

In western North America, models from foraging theory have been used to address subsistence change using archaeological faunas. Several studies have argued that return rates from foraging declined in a variety of late Holocene contexts and support this position by applying a method involving the computation of a relative abundance index (AI) of large bodied animals to the sum of large and small ones. We present the results of a series of computer simulations devised to identify the relationship between changes in such indices and changes in a forager's average return rate and discuss the implications of these simulations in light of our current work in the Little Boulder Basin Area of north-central Nevada. These include, (1) the importance of using knowledge of both post-encounter return rates and changes in AI s to make inferences about changes in overall return rates; (2) the fact that there are good reasons to expect AI values to be low; and (3) what factors might contribute to the high AI values observed at archaeological sites.     

Late Epipaleolithic hunters of the central Taurus: Faunal remains from Direkli Cave,Kahramanmaraş, Turkey

Newly initiated research at Direkli cave is helping to define an initial understanding of Epipaleolithic hunter‐gatherer traditions in the central Taurus region of southern Turkey. Detailed analysis of the Direkli faunal assemblage suggests that in the late Epipaleolithic the cave functioned as a short‐term logistical camp used to intercept wild goats (Capra aegagrus) in the high peaks around the cave, primarily in the late summer and fall. In addition, hunters opportunistically exploited deer and a variety of other small taxa, including tortoise, in the forested vicinity of the site. Evidence for low intensity and seasonal occupation of the cave indicates that Epipaleolithic foragers in the region were highly mobile, utilised a wide range of resources, but primarily scheduled use of the cave in order to exploit high ranked wild goat resources. This represents the first window into the nature of foraging systems just prior to the emergence of agricultural economies in this important region of Turkey. Copyright © 2010 John Wiley & Sons, Ltd.
