Adaptive Dietary Response to Long-Term Drought: Diachronic Stable Isotope Evidence from the Central Sierra Nevada, California (2017)
DOCUMENT Citation Only Bryna Hull. Jemer Eerkens. Reba Fuller.

This study examines human dietary responses to the Medieval Climatic Anomaly (MCA), an extended period of warmer and drier environmental conditions from AD 900-1300, in the Central Sierra Nevada Mountains of California. Stable isotope and radiocarbon analyses of human remains attributable to the Tuolumne Me-Wuk reveal individual-level dietary behaviors. Results show a region-specific "Central Sierran" pattern of resource use in the form of a distinctive isotopic signature relative to other areas...


Agouti commensalism? An open question in the prehistoric Lesser Antilles, West Indies (2017)
DOCUMENT Citation Only John Krigbaum. Christina Giovas. Scott Fitzpatrick.

Light isotope data for bone collagen, bone apatite, and tooth enamel apatite have been collected for prehistoric agouti (Dasyprocta sp.) recovered from secure archaeological contexts on Carriacou (Sabazan and Grand Bay) and Nevis (Coconut Walk) in the Lesser Antilles, West Indies. Stable carbon isotope ratios of individual specimens exhibit a wide range of values for both bone collagen (-20.0‰ to -11.5‰; avg = -17.8‰) and bone apatite (-13.6 to -6.5‰), with apatite-collagen spacing also quite...


An analysis of the Jamestown diet (2017)
DOCUMENT Citation Only Michelle Carpenter.

Our current knowledge of the historic fort of Jamestown in Virginia has developed through interpretation of the archaeological record and historical documents. The success of all colonies in the New World depended on the integral ability to produce food. Prior to developing a stable food source, the colonists at Jamestown relied heavily on those provisions they brought with them from England. We can learn about these provisions from ship manifests, colonists’ diaries, and inventory lists....


Ancient Origins of Ethnographic Shell Bead Money in Central California (2017)
DOCUMENT Citation Only Gregory Burns. Jelmer Eerkens.

Far from providing a bounty that obviated agriculture, the California acorn economy presented risks of secular variation more extreme than experienced by other densely populated hunter gatherers. Decentralized political organization and high ethno-linguistic diversity further complicated redistribution of spatio-temporally variant resources. In the ethnographic period, shell bead money played a key role in enabling exchange. We examine changing patterns in bead manufacture and distribution...


Animal diaspora and culture change (2015)
DOCUMENT Citation Only Naomi Sykes. Holly Miller.

Animal introductions are frequently equated with the introduction of new dietary ingredients; however, this paper will argue that access to 'meat' is seldom the motivation for the importation of exotic species. By examining a number of case-studies pertaining to Britain it will be proposed that many faunal introductions were both inspired by, and resulted in, social, economic and ideological change. Many species were associated with specific deities and because they were imported from beyond the...


Applications of Rat Bone Collagen Stable Isotope Analysis towards Investigating Long-term Island Socio-ecosystem Dynamics: Case studies from Mangareva (French Polynesia) and Pemba Island (Zanzibar) (2017)
DOCUMENT Citation Only Jillian Swift.

Stable isotope analysis of small commensal fauna provides a novel approach to paleoecological reconstruction and investigations of human site activities. The human translocation of rat species, especially the black rat (Rattus rattus), brown rat (R. norvegicus), and Pacific rat (R. exulans), has significantly—and often deleteriously—impacted native floral and faunal communities, particularly within island ecosystems. Rats are small-bodied omnivores with limited home ranges and highly generalized...


Assessing Dietary Variability at Gillman Mound, South Australia using Stable Carbon and Nitrogen Isotopes (2015)
DOCUMENT Citation Only Caitlin Smith.

The production, distribution, and consumption of food are central to the human experience. What we eat and how we prepare, consume, and share our victuals permeates every society, past and present. Therefore, it is crucial that our study of past human societies include attention to the role of foods and diet in our observations and interpretations of archaeological and biological data. Recent research in South Australia has highlighted the need for further exploration into the social structure...


Assessment of past subsistence strategy and environmental impacts using novel geochemical analyses of mollusk shells (2016)
DOCUMENT Citation Only C. Fred Andrus.

Archaeologists are beginning to apply two new analytical techniques to estuarine mollusk shells: inferring paleo-salinity from sclerochronological oxygen isotope profiles and assessing anthropogenic waste loading from mollusk nitrogen isotope measurements. These related approaches may offer insight into subsistence priorities and environmental alteration, but data from each should be interpreted with caution until these proxies are more completely validated. Potential uses and limitations of...

DOCUMENT Citation Only Olivia Franklin. John Dudgeon. Amy Commendador. Rebecca Hazard. Michael Dega.

Garapan, a Latte Period (A.D. 1000-1521) archaeological site in Saipan, Northern Mariana Islands, was excavated under mitigation efforts by Scientific Consultant Services, Hawaii in 2015. The recovery produced over 400 sets of skeletal remains, of which forty-eight were submitted for dietary bioarchaeological analysis in the Center for Archaeology, Materials and Applied Spectroscopy. This research focuses on the importance of marine versus terrestrial protein sources and introduced plant...


Bioarchaeological Research at Castillo de Huarmey, Peru (2017)
DOCUMENT Citation Only Wieslaw C. Wieckowski. Kelly Knudson. Lars Fehren-Schmitz.

The Wari imperial mausoleum, discovered in 2012-13 at the site of Castillo de Huarmey, Peru brought to light remains of 64 individuals buried within the main chamber underneath and additional seven in the contexts directly associated with the mausoleum. The upper layers of the building also yielded a collection of human and animal remains. The collection of human remains brings a unique set of data for bioarchaeologists. The research performed so far include standard analyses like taphonomy,...

Bone Carbonate Derived Stable Isotope Data and Aleut Diet Change (2015)
DOCUMENT Citation Only David Byers. Joan Coltrain.

In this poster, we build on an earlier study by using stable isotope data extracted from bone carbonate to evaluate the hypothesis that two behaviorally distinct groups of people, Paleo- and Neo-Aleut, occupied the eastern Aleutians after 1000 BP. This study focuses on directly dated burial assemblages from Chaluka midden, Ship Rock Island and Kagamil Island. We use the SISUS linear mixing model informed by isotopic data from Aleut faunal assemblages to address temporal and spatial variation in...


Breastfeeding, weaning and childhood diet in cave and megalithic populations of Late Neolithic north-central Spain (2017)
DOCUMENT Citation Only Teresa Fernández-Crespo. Andrea Czermak. Rick J. Schulting. Julia A. Lee-Thorp.

Stable carbon and nitrogen data of adult/adolescent human bone collagen from north-central Spanish Late Neolithic (ca. 3500-2900 cal. BC) provide evidence for the existence of significant isotopic differences among and between communities living in close proximity and burying their dead in caves and megalithic graves. This, together with previously identified distinct funerary selection patterns, suggests an unsuspected complex social or cultural differentiation. The purpose of this paper is to...


The Bridge River Dogs: A Comprehensive interpretation of aDNA and stable isotopes analysis obtained from dog remains (2016)
DOCUMENT Citation Only Emilia Tifental. Anna Marie Prentiss. Meradeth Snow.

Excavations at the Bridge River site have been on-going since 2003, increasing our understanding of the communities that inhabited the Middle Fraser Canyon, British Columbia, over 1,000 years ago. The most recent excavation at Housepit 54 in the summer of 2014 supplied further data regarding relationships between people and their dogs. Dogs are well documented in the Middle Fraser Canyon through both archaeological excavations and traditional knowledge. A household's possession of a dog has been...


The Canids of Arroyo Hondo: a reanalysis (2017)
DOCUMENT Citation Only Victoria Bowler. Emily Jones. Cyler Conrad.

Domestic dogs were an important part of human cultures in the prehistoric American Southwest; the significance of these animals is apparent from ceramic decorations and clay figurines, as well as faunal remains. But how these animals functioned within Southwestern cultures is less well-understood. Prehistoric dogs’ roles in some cases seem to have been similar to those of modern dogs: protector, worker, and pet. However, zooarchaeological data have shown that dogs, like turkeys, were also used...


Childhood Diet and Foraging in Prehistoric Central California (2015)
DOCUMENT Citation Only Alexandra Greenwald. Jelmer Eerkens. Eric Bartelink.

Ethnographic evidence demonstrates that hunter-gatherer children may forage effectively, where ecology, subsistence strategies, and social organization are conducive to juvenile participation. We hypothesize that, in easily navigated environments with food items accessible to children, juveniles will engage in assistive or independent foraging after a period of exclusive post-weaning parental provisioning, and that differences in male and female diets will reflect the sexual division of labor...


Considering Robustness and Vulnerability in Texas Hunter-Gatherer Social-Ecological Systems using Stable Isotope Data (2015)
DOCUMENT Citation Only Robert Hard. Jacob Freeman. Raymond Mauldin.

We analyze stable carbon and nitrogen isotopic data from over 200 foragers from inland, riverine, and coastal settings on the Texas Coastal Plain. Prehistoric foragers on the Texas Coastal Plain faced the challenge of maintaining a robust supply of food despite constant changes in their environments, including seasonal changes and changes that occurred over decades-to-centuries, like climate change and sea level rise. Given that coastal estuaries and inland river valleys had resources that...


The cultural ecology of Croatia’s cattle: stable isotope and zooarchaeological analyses of an indigenous breed (2017)
DOCUMENT Citation Only Emily Zavodny. Sarah B. McClure.

Here we present results from a preliminary stable isotope and zooarchaeology study of cattle from the Lika region of northern Croatia. During routine investigation of Bronze and Iron Age faunal assemblages, we identified bones belonging to a small unspecified cattle breed. These same specimens also have unexpected stable carbon and nitrogen isotope signatures, and are more similar to both domesticated and wild browsers than grazing cattle in other regions. We argue that these adaptations were...


Diet and Adaptations in a High Altitude Rockshelter of Southern Peru, Based on Stable Carbon and Nitrogen Isotopes (2017)
DOCUMENT Citation Only Sophia Haller Von Hallerstein. Dorothée Drucker. Katerina Harvati. Kurt Rademaker.

We present the results of stable carbon and nitrogen isotope analyses made on well-preserved collagen of four Early and one Middle Holocene adult humans together with coeval faunal remains of Cuncaicha rockshelter in the Peruvian puna to determine paleodiet. In addition, we reconstruct important aspects of the ecology of the Pucuncho Basin, in which Cuncaicha is located, using new as well as already available and secured values for stable carbon and nitrogen of archaeological and modern fauna...


Diet and in-migration in the Tlajinga District of Teotihuacan: New insights from stable isotope analysis and AMS radiocarbon dating. (2017)
DOCUMENT Citation Only Gina Buckley. Rebecca Storey. Scott Hynek. Kenneth G. Hirth. Douglas J. Kennett.

Thirty years ago, the apartment compound known as Tlajinga 33 (33:S3W1) in the southern district of Teotihuacan was extensively excavated, resulting in the recovery of over 100 individuals. A paleodemographic study of these individuals indicated that chronic morbidity was a serious health issue among residents. Additionally, previous geochemical analysis from 25 of these individuals suggested that at least 29% of residents grew up outside of Teotihuacan. Due to chronic health issues, the...


Diet and mobility patterns of hunter-gatherers and full-time farmers from the Tehuacan caves of Tehuacan, Puebla (2016)
DOCUMENT Citation Only Isabel Casar. Jose Ramon Gallego. Jose Concepcion Jimenez. Edith Cienfuegos. Pedro Morales.

The transition between the diet of the hunter-gatherers and the full-time farmers is described on an individual level based on evidence from three ancient caves in Tehuacan, Puebla. The populations studied occupied the caves for almost 8000 years from 6800 BC to AD 1520. The reconstruction of their diet was done on the basis of stable isotopic values of δ13C and δ15N of the bone collagen as well as the δ13C and δ18O from bone-bioapatite and from a series of slices from molars, alternating on...


Dietary and Environmental Reconstruction with Stable Isotopes of Early, Middle and Late Holocene Humans from Northern Malawi (2018)
DOCUMENT Citation Only Stanley Ambrose. Andrew Zipkin. Douglas J. Kennett. Abigail Fisher. Jessica Thompson.

The early Holocene African humid period (AHP, ~12,000-6000 bp) was followed by the Middle Holocene dry phase (MHDP, ~6000-3500 BP), and the modern climatic regime was established during the later Holocene (~3500 bp to present). The relationship of environmental change to human social and territorial organization adaptations are fairly well-documented in northern, eastern and southern Africa. However, the Holocene terrestrial record of environmental change in east-central Africa is poorly...


Dietary shift and cultural evolution relation to intercontinental cultural exchanges and climate change in the Hehuang and contiguous regions, northwest China ~3600 years ago: Evidence from Carbon and Nitrogen Stable Isotopic Analysis (2015)
DOCUMENT Citation Only MINMIN MA. Guanghui Dong. Hui Wang. Fahu Chen.

This study traces the extent to which dietary change coincides with intercontinental cultural exchanges in Eurasia, to enhance understanding of the effects of long-distance exchanges on the human diets. Through stable carbon and nitrogen isotope analysis of late Neolithic and early Bronze Age human and animal bone collagen, we find that intercontinental cultural exchanges in Eurasia led to significant changes in diet in the Hehuang and contiguous regions of northwest China. The isotopic evidence...


Earliest direct evidence of crop consumption in the central Tian Shan (Kazakhstan and Kyrgyzstan) (2015)
DOCUMENT Citation Only Giedre Motuzaite Matuzeviciute. Martin Kenneth Jones.

The main goal of this research is to explore the contribution of plant food to the diet of pastoral societies. It is still a subject of debate whether domesticated plants were being consumed and grown or just traded in this region during the Bronze Age, as the role of domesticated crops and their intensity of consumption in pastoral societies has been overlooked and until now hardly studied. This research presents the first results of stable carbon/nitrogen isotope analysis and archaeobotanical...


Effects of Sample Pretreatment and Contamination on Bivalve Shell and Carrara Marble δ18O and δ13C Signatures (2017)
DOCUMENT Citation Only Bernd R. Schöne. Katharina Schmitt.

Stable isotope signatures of bivalve shells serve as important proxies of past environmental conditions. However, such data can be biased as a consequence of physical and chemical pretreatment and contamination during sampling. To systematically assess these issues, homogenized aragonitic shell powder, as well as Carrara marble powder (calcite) were exposed to ultrasound, a set of different staining solutions and cleaning agents that are typically employed in bivalve sclerochronology....
