Title: “Biogeochemical and Bioarchaeological Approaches to Understanding Political and Environmental Change in the Andes”

Abstract: Around AD 1100, both environmental and political disruptions transformed the South Central Andes. Knudson will present bioarchaeological and biogeochemical data that was collected in order to understand the long-term impacts of the changes that occurred during the transition from the Middle Horizon to Late Intermediate Period. These data include radiogenic and stable strontium isotope values as well as light isotope data from hundreds of bone and enamel samples from the San Pedro de Atacama oases of northern Chile. By examining geographic origins, paleomobility, and paleodiet, and contextualizing these data with detailed investigations of mortuary contexts, the long-term impacts on both an individual and a community-level scale can be determined.
