This paper presents the first application of mammal tooth enamel carbonate stable isotope analysis for the purpose of investigating late Pleistocene–early Holocene environmental change in an Australian archaeological context. Stable carbon (δ13C) and oxygen (δ18O) isotope ratios were analyzed from archaeological and modern spectacled hare wallaby (Lagorchestes conspicillatus) and hill kangaroo (Osphranter robustus) tooth enamel carbonates from Boodie Cave on Barrow Island in Western Australia. δ18O results track the dynamic paleoecological history at Boodie Cave including a clear shift towards increasing aridity preceding the onset of the Last Glacial Maximum and a period of increased humidity in the early to mid-Holocene. Enamel δ13C reflects divergent species feeding ecology and may imply a long-term shift toward increasing diversity in vegetation structure. This study contributes new data to the carbonate-isotope record for Australian fauna and demonstrates the significant potential of stable isotope based ecological investigations for tracking paleoenvironment change to inter-strata resolution.

Climatic Records

AbstractExploring the role of changing climates in human evolution is currently impeded by a scarcity of climatic information at the same temporal scale as the human behaviors documented in archaeological sites. This is mainly caused by high uncertainties in the chronometric dates used to correlate long-term climatic records with archaeological deposits. One solution is to generate climatic data directly from archaeological materials representing human behavior. Here we use oxygen isotope measurements of Bos/Bison tooth enamel to reconstruct summer and winter temperatures in the Late Pleistocene when Neandertals were using the site of La Ferrassie. Our results indicate that, despite the generally cold conditions of the broader period and despite direct evidence for cold features in certain sediments at the site, Neandertals used the site predominantly when climatic conditions were mild, similar to conditions in modern day France. We suggest that due to millennial scale climate variability, the periods of human activity and their climatic characteristics may not be representative of average conditions inferred from chronological correlations with long-term climatic records. These results highlight the importance of using direct routes, such as the high-resolution archives in tooth enamel from anthropogenically accumulated faunal assemblages, to establish climatic conditions at a human scale.

This chapter discusses human migration and multiethnicity in Copan, a Maya archaeological site in modern Honduras. A broad skeletal sample from the site has been studied through basic osteology, mortuary archaeology, and archaeochemistry (stable isotope analysis). The combined results show that the ancient city had a significant number of immigrants from all over the Maya Area. There was no sex or age related distinction, nor socioeconomic exclusivity, among these immigrants. In such a multiethnic city, biocultural body modifications, like dental decorations and intentional head shaping, were indicative of their social identities, especially “Mayahood.” The dynamic changes of these biocultural attributes at spatial and chronological scales are evidence of shifting social identities at the southeastern borderland of the Maya Area.

And Migration

Stable isotope analysis is firmly established as a method for the investigation of past population mobility. The distinction between local and non-local individuals within a cemetery population relies on identifying an individual’s place of childhood residence through the analysis of strontium and oxygen isotopes present in human tooth enamel. Traditionally, studies investigating mobility focus on the analysis of a single tooth. More recently, however, it has become apparent that in order to investigate the mobility of an individual during childhood—and thus to consider the importance of children in the migration process—it is necessary to analyse a series of teeth which form at different stages during the early years of life. This chapter will consider the potential of—and challenges surrounding—this scientific approach to the investigation of childhood mobility in the past.

Habitat Usage

The activity levels of seven species of insectivorous microbats in five habitats widespread across the Charles Darwin Reserve in the Murchison region of Western Australia were measured using echolocation detectors and compared with results of habitat usage revealed by stable isotope analysis. The activity levels were further compared with projective foliage density as a surrogate of productivity within each habitat. Habitat use, estimated from echolocation activity of the microbat species and from stable isotope analysis of their fur, agree and each provides complementary information on the habitats preferred by species. Both methods show that five of the species, Chalinolobus gouldii, C. morio, Mormopterus species 3, Nyctophilus geoffroyi and Tadarida australis, are active and forage over each of the five habitats. Scotorepens balstoni is shown by both methods to prefer habitats with C3 woodland over C4 shrubs and grasses. Vespadelus baverstocki is shown by both methods to fly and forage over habitats with developed arid-zone shrubland understorey vegetation. The echolocation method shows that bat activity levels align with the foliage mass of the vegetation as measured by the projected foliage density. The species’ stable isotope signatures show that the insects captured are feeding primarily on the ground cover of the habitats. The two species that have high δC signatures, S. balstoni and V. baverstocki, are shown to be most active in habitats with a C4 ground cover.

Stable isotope analysis refers broadly to a series of chemical methods used to study phenomena such as earth systems, the hydrological cycle, and ecology. The use of stable isotopes in anthropology traces its beginnings to the late 1970s. Originally focused on geological, hydrological, and ecological problems, stable isotope analysis now is a major component of the anthropologist’s toolkit. Current applications within anthropology draw from the core scientific disciplines but adapt these methods for specific research questions within archaeology, bioarchaeology, paleoanthropology, and forensic anthropology. One major area of study is dietary reconstruction, which focuses on isotope analysis of human skeletons to examine temporal and regional dietary patterns, as well as variation associated with sex, age, mortuary patterns, and social status. More specialized approaches examine weaning and childhood diet patterns using serial sections of tooth enamel and dentin. Another major area of isotope research in anthropology is the study of past residence patterns (e.g., migration and mobility). Some stable isotopes record information about the local water and geology, and thus provide information regarding the place of origin or travel history of an individual. By examining multiple isotopes in different tissues, anthropologists can reconstruct changes in residence patterns. For example, isotopes in enamel bioapatite (mineral fraction) do not change throughout life, so teeth provide a record of where a person lived when a particular tooth formed. Bone collagen (organic fraction) and bioapatite (mineral fraction), in contrast, are constantly replaced through remodeling; thus, if a person moved to a new geographic region, the isotope values in their bones will shift toward the new location over time. By comparing the isotopes in teeth versus bones, anthropologists can detect whether a person was local or nonlocal to the area where they died. In instances where hair or nails are preserved (e.g., mummies, modern forensic cases), serial sections of these tissues can be used to provide a detailed record of diet or travel history in the months prior to death. More recently, forensic anthropologists have begun to examine stable isotopes in modern human remains to aid with medicolegal identification. These methods are especially useful when a decedent is nonlocal to the area where they died (for example, a recent traveler or foreign-born individual).

Abstract Limited numbers of high-resolution records predate the Last Glacial Maximum (LGM) making it difficult to quantify the impacts of environmental changes prior to peak glaciation. We examined sediments from Last Canyon Cave in the Pryor Mountains of Montana and Wyoming to construct a >45 ka environmental record from pollen and stable isotope analysis. Artemisia pollen was hyper-abundant at the beginning of the record. Carbon isotope values of bulk organic matter (>40 ka) showed little variation (-25.3 ± 0.4‰) and were consistent with a arid C3 environment, similar to today. After 40 cal ka BP, Artemisia pollen decreased as herbaceous taxa increased toward the LGM. A significant decrease in δ13C values from 40–30 cal ka BP (~1.0‰) established a new baseline (-26.6 ± 0.2‰), suggesting cooler, seasonally wetter conditions prior to the LGM. These conditions persisted until variation in δ13C values increased significantly with post-glacial warming, marked by two spikes in values at 14.4 (-25.2‰) and 13.5 cal ka BP (-25.4‰) before δ13C values dropped to their lowest values (-26.9 ± 0.2‰) at the onset of the Younger Dryas (12.8 ka). These results provide insights into late Pleistocene conditions and ecological change in arid intermontane basins of the Rocky Mountains.
