1-25 (144 Records)
This is an abstract from the "Novel Statistical Techniques in Archaeology I (QUANTARCH I)" session, at the 84th annual meeting of the Society for American Archaeology. Currently, an alarming number of plants and animals are on the brink of extinction due to habitat loss caused by human activities and climate change. Though numerically unprecedented, this may not be the first instance of a human-driven mass extinction. For decades, scholars have hypothesized that human predation led to the...
3D Hydraulic Modeling of the Ancient Irrigation System at the MGK site in Xinjiang, China (2018)
Most archaeologists would agree that ancient irrigation systems preserve important information about the technology, economy, and social organization of past societies. However, considering that archaeologists generally lack training in hydraulics, it is often difficult for us to extract much information from an ancient irrigation system beyond basic description and chronology. Thanks to the recent development in drone technology and flow modeling techniques we now have the option of generating...
Adding Navigating Capabilities to a Deterministic Computer Model of Ocean Voyaging (2019)
This is an abstract from the "Modeling Mobility across Waterbodies" session, at the 84th annual meeting of the Society for American Archaeology. Since pioneering efforts in the 1970’s, computer models that simulate vessel displacement have contributed useful information to the debate around several historical and archaeological problems. Existing models can be separated into two categories. In stochastic models, wind and current values are based on a probabilistic description of these...
An Agent-Based Disaster Model: Marginality, Decision-Making, and Novel Resource Exploitation during ENSO Flooding Events in Chicama, Peru (2019)
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. Ecological disasters are often argued to be forces of large-scale societal change, including the primary causes of major cultural collapses. This concept is reevaluated in light of the recent 2016-2017 El Niño Southern Oscillation (ENSO), which provides an opportunity to examine the ways in which this event affects the landscape. Through integration of remote...
An Agent-Based Model to Explore the Relationship between Archaeological Assemblages, Past Social Networks, and Cultural Dynamics (2021)
This is an abstract from the "SAA 2021: General Sessions" session, at the 86th annual meeting of the Society for American Archaeology. The need to relate static archaeological sites to the dynamic processes responsible for their formation is central to the utility of archaeological data for testing hypotheses about the lives of prehistoric humans, and how ecological and social changes affected them. Here we use an agent-based simulation to investigate how different factors influence the...
Agricultural Niche Construction in Roman North Africa: Simulating Irrigation and Deforestation on a Desert Margin (2018)
Earth system models are climate models capable of simulating land-atmosphere feedbacks and the complex biogeochemical and biogeophysical processes that drive them. These models are particularly well-suited to studying the impact of preindustrial land use on regional climate change, as they explicitly resolve the impacts of irrigation, deforestation, and agropastoral production on the flow of water and energy between the land and atmosphere. Generating realistic maps of past land use is a...
An Application of Hierarchical Bayesian Modeling to Upper Paleolithic Archaeological Cultures in France between 32 and 21 cal ka BP (2021)
This is an abstract from the "Constructing Chronologies I: Stratification and Correlation" session, at the 86th annual meeting of the Society for American Archaeology. Investigations of chronology play a key role in the majority of archaeological research endeavors and are particularly pertinent to examinations of culture-environment relationships, especially during periods marked by pronounced climatic variability. Rigorous evaluations of data and robust methods are necessary to reconstruct...
Archaeological Expansions in Tropical South America during the Late Holocene: Assessing the Role of Demic Diffusion (2021)
This is an abstract from the "SAA 2021: General Sessions" session, at the 86th annual meeting of the Society for American Archaeology. Human expansions motivated by the spread of farming are one of the most important processes that shaped cultural geographies during the Holocene. The best known example of this phenomenon is the Neolithic expansion in Europe, but parallels in other parts of the globe have recently come into focus. Here, we examine the expansion of four archaeological cultures...
The Archaeology of Travel in Greater Nicoya (2018)
Sometime before AD 1, a dynamic interaction and exchange network developed among the villages and hamlets of Greater Nicoya. The range and frequency of trade within this region is demonstrated by geochemically sourced ceramic and stone artifacts. The travel routes along which these artifacts were traded remain poorly understood. Geographic information systems (GIS) offer a means to predictively model the optimal terrestrial and aquatic travel routes that interconnected the settlements of Greater...
The Architectural and Urban Design Principles of Tenochtitlan (2018)
There exists a vast literature examining every aspect of Aztec culture. Despite this, few studies focus specifically on Aztec architecture and its implications for understanding broader aspects of Aztec cosmology. This paper contributes to our knowledge of Aztec society through an exploration of architectural and urban design principles that guided the building of their cities and ceremonial precincts. By examining ethnohistoric and archaeological sources, and drawing on evidence from several...
ArchMatNet: An Agent-Based Model to Investigate the Validity of Social Networks in Archaeology (2023)
This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology. Archaeological network studies use characterizations of many kinds and aspects of material culture (e.g., sourcing, style, technology) as proxies for social relations. Yet, it is often unclear what types of interactions are indicated by material culture. Social network analysis is a useful tool because it provides a set of methods and theoretical...
Are Changes in Rates of Technological Change Robust to Error? A Paired Bayesian and Simulation Approach to Assessing the Pleistocene Record (2023)
This is an abstract from the "The Expanding Bayesian Revolution in Archaeology" session, at the 88th annual meeting of the Society for American Archaeology. Observed changes in rates of technological change play important roles in many models seeking to explain or identify the greater adaptability of some hominins over others, adaptation to changing environments, and many other processes. We quantify how robust detection of a shift in the rate of technological change is to error in measuring...
Assessing Impacts of Late Holocene Environmental Variability on the Demography of Prehispanic Societies in Northern Chile (18°-29°S) (2018)
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...

We seek to use mathematical graph theory to manage both stratigraphic and chronological information during Bayesian...
Basketmaker III in the Central Mesa Verde Region: Transitions, Social Dynamics, and Population Growth (2019)
This is an abstract from the "Adopting the Pueblo Fettle: The Breadth and Depth of the Basketmaker III Cultural Horizon" session, at the 84th annual meeting of the Society for American Archaeology. The Basketmaker III period (A.D. 500 to 725) in southwestern Colorado was a time of fundamental social and demographic change. The area witnessed dramatic population growth after A.D. 600 that was due to immigration and increases in fertility. This growth was accompanied by changes in settlement...
Bayesian Exponential Random Graph Modeling of an Iron Age Burial Network in Northeastern Taiwan (2021)
This is an abstract from the "Bayesian Archaeology" session, at the 86th annual meeting of the Society for American Archaeology. Burials provide valuable information to study social structures and discuss social inequality. The relationship between prestige goods among burials may reflect the social relations between individuals, since prestige goods usually relate to social practices of trade, exchange, and gifting. We ask whether European colonial activities in seventeenth-century Taiwan...
Beringia Underwater: The Search for New Archaeological Sites on the Pacific Northwest Coast (2021)
This is an abstract from the "Advances in Global Submerged Paleolandscapes Research" session, at the 86th annual meeting of the Society for American Archaeology. When and how people first arrived in the Americas remains one of archaeology’s greatest mysteries. The earliest archaeological evidence suggests that people migrated from Siberia across the Bering Strait, Beringia, and into Alaska around 14,000 years ago. Where they went from there is still unclear! One hypothesis is that these First...
Boat Engravings and Maritime Technologies in the Megalithic Ages 4700–2500 cal BC (2023)
This is an abstract from the "Negotiating Watery Worlds: Impacts and Implications of the Use of Watercraft in Small-Scale Societies" session, at the 88th annual meeting of the Society for American Archaeology. Recent research into megalithic temporality, mobility, and symbolic identity suggests that the rise of long-distance maritime journeys began in Europe as early as the megalithic era. Megaliths emerged in northwest France (~4700–4200 cal BC) and then spread over the seaways along...
Bonita Canyon: A Chronology of Prehistoric Occupation and Predictive Analysis of Archaic Sites (2019)
This is an abstract from the "Partners at Work: Promoting Archaeology and Collaboration in the Chiricahua Mountains" session, at the 84th annual meeting of the Society for American Archaeology. One of the goals of the Student Conservation Association (SCA) is to develop the next generation of conservation leaders. While the focus is often on natural resources, cultural resources, as a nonrenewable resource, have, until recently, been neglected. Chiricahua NM has been partnering with the SCA...

This is an abstract from the "2023 Fryxell Award Symposium: Papers in Honor of Timothy Beach Part II" session, at the 88th annual meeting of the Society for American Archaeology. Comprehensive maps of ancient structures across the Maya area of Central America can help archaeologists to deepen knowledge of past settlement patterns and regional interactions, potentially leading to enhanced understanding of thousands of years of Maya civilization. However, most Maya archaeological sites are not...
Building Nearest Neighbor Models of Hunter-Gatherer Settlement Systems Using Four Case Studies for the Northwest Coast of North America (2019)
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. Spatial analysis of settlement patterns have traditionally focused on hierarchical city states. Seldom do settlement pattern studies use spatial statistics to characterize hunter-gatherer settlement systems. Through the application of nearest neighbor analysis this paper characterizes the settlement patterns for four sub-regions of the Northwest Coast of North...
Changes to the Western Eurasian Hominin Climate Niche (2019)
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. The climate niches that early modern humans and our earlier hominin ancestors inhabited have undergone major changes over time. This study documents climate niche expansions, contractions, and stationarity across four time periods (Last Interglacial, Last Glacial Maximum, Mid-Holocene, and 1950¬–2000) in western Eurasia. Using spatially gridded global...
Climate Change and the Foraging-Farming Transition on the Great Plains (2019)
This is an abstract from the "Novel Statistical Techniques in Archaeology I (QUANTARCH I)" session, at the 84th annual meeting of the Society for American Archaeology. The foraging lifestyle persisted as the major human subsistence strategy worldwide for most of the human career. With notable exceptions, this way of life was eventually replaced by a subsistence base complemented and often dominated by cultivated foods. Archaeologists have proposed several hypotheses to explain this...
Competing with the Crown: Early Spanish Mission Settlement Decisions in a Human Behavioral Ecology Model (2018)
Models developed from principles in human behavioral ecology have long benefited archaeological research. Drawing on natural features in the modern landscape, locations of prehistoric settlements can be evaluated in terms of calculable suitability. Such models also have predictive potential, as they can rank loci in terms of any combination of environmental conditions appropriate to the archaeological context being investigated. Where available, careful examination of ethnohistoric and...
