  • Assessing Impacts of Late Holocene Environmental Variability on the Demography of Prehispanic Societies in Northern Chile (18°-29°S) (2018)
    DOCUMENT Citation Only Eugenia Gayo. Calogero Santoro. Claudio Latorre. Virginia Mcrostie. Jose M. Capriles.

    Agricultural communities began to spread over much of the Atacama Desert (18°-29°S) at 3.5 ka BP, triggering unprecedented levels of population growth. In inland areas and particularly along desert oases, this phenomenon featured increasing complexity in food-production systems and sedentary lifestyles with population aggregating in architecturally complex villages. Whereas, littoral populations maintained marine foraging and fishing strategies with limited inland food-resources. Both lifestyles...

  • Climate Change, Economies of Scale, and Population Growth in Prehistoric Hunter-Gatherer Societies: A Case Study from Southwestern Wyoming (2018)
    DOCUMENT Citation Only Erick Robinson. Jacob Freeman. David A. Byers. Spencer R. Pelton. Robert L. Kelly.

    Increasing energy consumption returns, or economies of scale, have been illustrated similarly for modern urban societies and ancient complex societies. However, the relationship between underlying scaling relationships and the development and decline of population and social complexity over the long-term are yet to be investigated. This poster addresses their role in hunter-gatherer societies. Using formal mathematical models from macroeconomics, we examine the long-term variability of economies...

  • Contrasting Human Demography Trends between Hunter-Gatherers and Farmers as Response to Climate Change: Central Western Argentina as Study Case (2018)
    DOCUMENT Citation Only Adolfo Gil. Gustavo Neme. Ricardo Villalba. Jacob Freeman.

    The Late Holocene archaeological record of central western Argentina shows a mosaic of human strategies, ranging from farmers to hunter-gatherers. This presentation evaluates if differences in subsistence practices among groups in a similar biophysical environmental generated different demographic and socio ecological responses to climatic change over the last 3000 years. We use radiocarbon dates as a proxy for human population size and growth rates and 13C and 15N stable isotopes on human bone...

  • Demographic Change through Analysis of Age Profiles of Burial Data (2018)
    DOCUMENT Citation Only Kristin Corl. Kristina Solis. Robert J. Hard. Michelle Carpenter.

    A series of mortuary sites on the Texas Coastal Plain provide a dataset useful for analyzing demographic change through examination of age profiles. Other archaeological data suggest that populations peaked during the Late Archaic period (4000-800 BP) and sharply declined during the Late Prehistoric period (800-350 BP). Analysis of the ratio of adults to young individuals has been used to identify rapid population growth among other populations. Hunter-gatherer groups living in the Texas...

  • Does Increasing Social Complexity Buffer Energy Consumption from the Effects of High Frequency Climate Variation? A Western European Case Study (2018)
    DOCUMENT Citation Only Samantha Nabity. Jacopo Baggio. Jacob Freeman.

    Humans, like any other organism, must continuously adapt to or modify their surrounding environment to maximize their fitness. One of the main sources of environmental variation that humans must cope with is climate variation. Adjustment to climate variation may include increasing investments in infrastructure (social, technological, cognitive), which acts as a buffer, filtering out the effects of higher frequency climate variation on the ability of individuals and populations to consume energy,...

  • The Effects of Economic Complexity and Temperature on the Long-Term Energy Consumption Dynamics of Human Societies (2018)
    DOCUMENT Citation Only Jacob Freeman. Gideon Maughan. Erick Robinson. David Byers. Robert L. Kelly.

    Increases in energy consumption correlate with social and political development in human societies, as well as increasing human impacts on ecosystems. Thus, understanding the underlying drivers of energy consumption in human societies may provide insights into the processes of social evolution and rapid social change (collapse). In this paper, we develop a model of energy consumption in human societies based on population size, economic complexity and temperature. We demonstrate the usefulness...

  • Fremont Maize Cultivation and Latest Holocene Climate Variability in the Cub Creek Archaeological District, Dinosaur National Monument (2018)
    DOCUMENT Citation Only Judson Finley. Erick Robinson. R. Justin Derose. Elizabeth Hora-Cook.

    The Cub Creek Archaeological District in northern Utah’s Dinosaur National Monument was an early center of Fremont maize cultivation and village settlement AD 450-850. Cub Creek lies near the northern limit of maize cultivation in western North America in the foothills of the Uinta Mountain Range. We couple a Bayesian analysis of radiocarbon-dated pithouses and roasting features with a 2,115-year tree-ring reconstruction of August-July precipitation to explore relationships between Fremont...

  • Global and Regional Frameworks for Comparing Agricultural Intensification and Productivity Across Cases (2018)
    DOCUMENT Citation Only Amber Johnson. Rudolf Cesaretti. Christina Collins. Peter Turchin.

    Understanding variation in the stability and productivity of subsistence strategies is fundamental to explaining patterns of variation in long-term human demography. This poster addresses under what conditions societies intensify food production at both global and regional scales using frameworks ranging from relatively abstract environmental measures to models based on detailed historical and archaeological data relating to agricultural productivity. At a global scale, the combination of...

  • Human Demography and Ecosystems: Comparative Approach of Human Age-at-Death Profiles from Northpatagonia (Southern Mendoza, Argentina) (2018)
    DOCUMENT Citation Only Eva Peralta. Leandro Luna. Claudia Aranda. Adolfo Gil.

    The aim of this presentation is to provide information about human age-at-death profiles in order to understand the environmental/demographic dynamics of pre-Hispanic people from Southern Mendoza. Burials from 20 archaeological sites are included in age-at-death profiles, which are compared to discern regional particularities. This is a transitional area between hunter-gatherers groups and farming populations. The presentation evaluates if the introduction of domesticated resources in the diet...

  • Late Holocene Climate Change and the Emergence of Hunter-gatherer Territoriality in the Late Archaic Texas Coastal Plains: An Analysis using Bioavailable Strontium (2018)
    DOCUMENT Citation Only Kristina Solis.

    The Late Holocene was a time of sea level stability, increased moisture, and abundant resources. Existing models suggest that this environment set the stage for population packing and territoriality. In this presentation, strontium isotope ratios from the Loma Sandia mortuary site (2800-2600 BP) are used to evaluate the emergence of territoriality among hunter-gatherer populations on the Texas Coastal Plain. Assessing territoriality with human strontium data is facilitated by determining the...

  • Modeling Hunter-Gatherer Population Dynamics on the Texas Coastal Plain during the Holocene (2018)
    DOCUMENT Citation Only Robert Hard. Jacob Freeman. Robert Gardner. Gabriella Zaragosa. Raymond Mauldin.

    A radiocarbon database is used to model prehistoric population dynamics on the Texas Coastal Plain in the context of Holocene climate change. Hunters and gatherers participated in a multifaceted social and ecological system that appears to have been highly resilient to climatic impacts by utilizing multiple ecological zones and participating in wide-ranging social networks for over 6000 years. Climatic fluctuations include a dry middle Holocene and fluctuating but wetter late Holocene. During...

  • PEOPLE 3K (PalEOclimate and the PeopLing of the Earth): Investigating Tipping Points Generated by the Climate-Human Demography-Institutional Nexus over the Last 3000 Years (2018)
    DOCUMENT Citation Only David Byers. José M. Capriles. Adolfo Gil. Judson Finley. Jacob Freeman.

    One of the least understood aspects of paleoscience is the interplay between climate, human demography, and how changes in population influence resource management strategies. With the goal of understanding such processes, we created the PEOPLE 3000 research network to study trade-offs inherent to the climate-human population-institutional adaptation system over the last 3000 years. We propose that strategies reducing variation in food production and institutions for protecting those strategies...

    From the civilizations in Easter Island to the Mayas or to the collapse of the prehistoric populations in the Great Basin, researchers have proposed a wide range of hypotheses to disentangle the causes and drivers behind such pronounced demographic change. PeoPLE (PalEOclimate and the PeoPLing of the Earth) 3K is a new working group recently created by Past Global Changes (PAGES) to examine in detail how environmental change over the last 3000 years has affected, either by facilitating...

  • Rates of Change in Radiocarbon Date Frequencies and Population Collapse (2018)
    DOCUMENT Citation Only Darcy Bird. Jacob Freeman.

    Recent analyses of large samples of radiocarbon dates shows a change in radiocarbon date frequencies between 3000 BP and 800 BP. There is either an exponential or super-exponential increase in radiocarbon date frequencies followed by a sudden decline. The goal of this poster is to test a population ecology model as to whether or not the degree of population overshoot can predict the degree of population collapse. We want to analyze if the rate of increase in radiocarbon date frequencies over...
