The role of shellfish in the diet of hunter-gatherers in North America is poorly understood. Specifically, the interpretation of freshwater gastropods from archaeological sites as food remains has been a subject of professional debate. Data from the Hayes site (40ML139), a stratified Archaic midden on the Duck River in Tennessee, suggest that freshwater gastropods were procured in considerable quantities and utilized as a food resource. Evidence supporting this interpretation includes (1) quantities of gastropods in the midden, (2) stratigraphic relationship between shell-bearing strata and shell-free strata, and (3) pH analysis of associated sediments. Although gastropods provide relatively little meat and are a poor source of food energy compared to other animal species such as deer, they contain relatively high concentrations of several important vitamins and minerals. Thus, their primary value may have been nutrient content rather than food energy. This consideration, coupled with seasonal variation in their availability, suggests summer and/or fall as most likely periods of gastropod procurement.

This paper evaluates previous models of cave and rockshelter use in the American Midsouth from the Early to the Middle Archaic periods. Four sites are compared in order to identify variability in activities, seasonality, occupation intensity, and function. Focus is placed on using the often overlooked feature assemblages to discern these activities. Data suggest that the changing use of many caves and rockshelters is not one of longer term occupation as base camps, as has been previously argued, but rather as specialized field camps dedicated to the processing of mast resources. This shift takes place as Middle Holocene warming prompted hunter-gatherers to adopt a more logistical mobility strategy in order to take advantage of the spatio-temporal variance associated with increased mast availability. It is further argued that these sites were likely locations of women's activities and that foraging in the Midsouth involved groups of women engaged in daily tasks centered around mast, tasks that over time imbued caves and rockshelter s with symbolic meaning such that they came to function simultaneously as both processing camps and as persistent places of ritual significance in the hunter-gatherer taskscape.

This study is the first systematic approach to ceramic miniatures from the lowlands of the Paraná River (northeastern Argentina), which have received marginal attention from regional archaeology. This paper presents an analysis of 24 pottery miniatures recovered from archaeological sites generated by complex Late Holocene hunter-gatherers, dating from between 460±50 and 1056±47 years bp. Morphological and decorative data, errors of manufacture, traces of use and the context of the pieces’ deposition are recorded in order to explore aspects of their variability and functionality. The miniatures correspond to bowls, basins, cups and ‘bell’ artefacts, all of which are commonly found in the regional record. The data obtained suggest that at least some of the sample were used in the symbolic sphere, such as burial offerings.

Concepts of residential and logistic mobility are applied to survey assemblages from multiple decades of research along the interior drainages of central lower Michigan. Drawing on the ethnographic record of boreal hunter-gatherers and archaeological interpretations of long-distance logistic mobility from the Mesolithic of northern England and continental Europe, it is argued that the importance of logistic mobility is underrepresented in summaries of northern hemisphere hunter-gatherers. Reconstruction of Middle Holocene environments suggests that the resource structure of the central Michigan uplands was one that fostered use of logistic mobility, and that interior Middle Archaic assemblages and site structures reveal special function activities systemically tied to residential and other special function sites at lower coastal elevations, as well as currently submerged under Lake Huron. We conclude that rising levels of Lake Huron ca. 4500 B.P. resulted in decreased land area, population packing, and a consequent shift to residential mobility by the Late Archaic. Further, the results of this analysis can serve as a comparative framework for recognizing the role of logistic mobility in the evolution of hunter-gatherer adaptive strategies in other regions.

Within the past 20 years, archaeobotanical research in the Eastern United States has documented an early agricultural complex before the dominance of the Mesoamerican domesticates (corn, beans, and squash) in late prehistoric and historic agricultural systems. This early agricultural complex consisted of domesticated plants such as Iva annua var.macrocarpa (Sumpweed or Marshelder), Hellanthus annuus (Sunflower) and Chenopodium berlandieri, (Goosefoot or Lasbsquarters), and heavily utilized plants such as Polygonum erectum (Erect Knotweed), Phalaris caroliniana (May grass), and Hordeum pusillum (Little Barley).Recent research involving the use of Scanning Electron Microscopy (SEM) specifically on Chenopodium has established diagnostic traits of wild and domesticated species seeds. This is important because carbonized or uncarbonized seeds are the most commonly recovered Chenopodium material from archaeological sites. The diagnostic seed traits assist archaeobotanists in identification of Chenopodium remains and provide a basis for evaluation of Chenopodium utilization in a culture's subsistence patterns. With the aid of SEM, an analysis of Chenopodium remains from three Late Prehistoric sites in Northwest Iowa (Blood Run [Oneota culture], Brewster [Mill Creek culture], and Chan-Ya-Ta [Mill Creek culture]) has been conducted to: 1) attempt seed identification to a species level, 2) evaluate the traits of the seeds for classification as either wild or domesticated, and 3) evaluate the role of Chenopodium utilization in both the Oneota and Mill Creek cultures.

AbstractGlobally landscape fires produce about 256 Tg of pyrogenic carbon or charcoal each year. The role of charcoal as a source of environmentally persistent free radicals, which are precursors of potentially harmful reactive oxygen species, is poorly constrained. Here, we analyse 60 charcoal samples collected from 10 wildfires, that include crown as well as surface fires in forest, shrubland and grassland spanning different boreal, temperate, subtropical and tropical climate. Using electron spin resonance spectroscopy, we measure high concentrations of environmentally persistent free radicals in charcoal samples, much higher than those found in soils. Concentrations increased with degree of carbonization and woody fuels favoured higher concentrations. Moreover, environmentally persistent free radicals remained stable for an unexpectedly long time of at least 5 years. We suggest that wildfire charcoal is an important global source of environmentally persistent free radicals, and therefore potentially of harmful reactive oxygen species.

Abstract There is a northern Thai story that tells how the naga—a mythical serpent—came and destroyed the town known as Yonok (c. thirteenth century) after its ruler became immoral. Despite this divine retribution, the people of the town chose to rebuild it. Many archaeological sites indicate resettlement during this early historical period. Although many temple sites were constructed in accordance with the Buddhist cosmology, the building patterns vary from location to location and illustrate what this paper calls ‘nonconventional patterns,’ distinct from Theravada Buddhist concepts. These nonconventional patterns of temples seem to have been widely practiced in many early historical settlements, e.g., Yonok (what is now Wiang Nong Lom). Many local written documents and practices today reflect the influence of the naga myth on building construction. This paper will demonstrate that local communities in the Chiang Saen basin not only believe in the naga myth but have also applied the myth as a tool to interact with the surrounding landscapes. The myth is seen as a crucial, communicated element used by the local people to modify and construct physical landscapes, meaning Theravada Buddhist cosmology alone cannot explain the nonconventional patterns. As such, comprehending the role of the naga myth enables us to understand how local people, past and present, have perceived the myth as a source of knowledge to convey their communal spaces within larger cosmological concepts in order to maintain local customs and legitimise their social space.

Humans regularly cooperate with non-kin, which has been theorized to require reciprocity between repeatedly interacting and trusting individuals. However, the role of repeated interactions has not previously been demonstrated in explaining real-world patterns of hunter–gatherer cooperation. Here we explore cooperation among the Agta, a population of Filipino hunter–gatherers, using data from both actual resource transfers and two experimental games across multiple camps. Patterns of cooperation vary greatly between camps and depend on socio-ecological context. Stable camps (with fewer changes in membership over time) were associated with greater reciprocal sharing, indicating that an increased likelihood of future interactions facilitates reciprocity. This is the first study reporting an association between reciprocal cooperation and hunter–gatherer band stability. Under conditions of low camp stability individuals still acquire resources from others, but do so via demand sharing (taking from others), rather than based on reciprocal considerations. Hunter–gatherer cooperation may either be characterized as reciprocity or demand sharing depending on socio-ecological conditions.
