This is an abstract from the "Central Mexico after Teotihuacan: Everyday Life and the (Re)Making of Epiclassic Communities" session, at the 86th annual meeting of the Society for American Archaeology. The site of Chicoloapan Viejo represents a long-term occupation that spanned multiple cultural phases, each associated with changes in population size, settlement pattern, and sociopolitical organization. These changes were also accompanied by climatic fluctuations of varying intensity. This...
Regional Settlement, Subsistence, and Environment after the Demise of Teotihuacan (2024)
This is an abstract from the "What Happened after the Fall of Teotihuacan?" session, at the 89th annual meeting of the Society for American Archaeology. Significant changes in sociopolitical and economic organization following the collapse of the Teotihuacan state between the sixth and seventh centuries CE are evident in settlement patterns as well as archaeological materials including ceramics and lithics. The potential magnitude of this event and subsequent ramifications within the valley...
Remote Sensing of Anthropogenic Vegetation in Sierra Sur, Oaxaca, Mexico (2017)
Geospatial technologies, such as remote sensing and LIDAR, have enabled archaeologists to capture high-resolution information about landscapes and settlement patterns thus contextualizing sites through a wider landscape perspective. These tools have also facilitated the detection of otherwise "invisible" archaeological sites through image or spectral analyses and other visualization techniques. This paper examines the performance of vegetation indices for the detection of anthropogenic...
The Rise and Fall of the Forest Canopy: An Application of Compound-Specific Stable Isotopic Analysis to a Holocene Sequence of Soils as a Record of Human Impacts in Southern Belize (2018)
Derived from lipid-rich plant tissues (primarily leaf waxes), long chain n-alkanes are a durable organic biomarker whose relative abundance is used in paeloecological studies as a proxy marker of plant species composition, and as an indicator of biomass burning. Isotopic composition of individual n-alkane components preserves signals that reflect both hydroclimate and canopy height. These properties can be employed to examine spatially integrated signals of anthropogenic land clearance in lake...
Ritual Production, Commodity Production, and Cultivating Agricultural Heritage in Ravni Kotari, Croatia (2018)
Agricultural crops may be selected not only because they "work" from the perspective of agroecology, but also for their value in maintaining religious affiliation, historical memory, and community identity. Drawing on emerging archaeobotanical evidence from the Ravni Kotari region of southern Croatia, this paper discusses the challenges of understanding continuities of cultivation practices over multiple millennia in relation to changing political-economic contexts within which cultivation has...
Riverine Resource Subsistence in Early to Middle Woodland Saginaw Valley, Michigan: An Investigation of Site 20SA1427 (2019)
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. From the terminal Early to late-Middle Woodland periods (500 BC – AD 500), Native groups living in the central Saginaw Valley of Michigan dramatically shifted subsistence strategies from a reliance on medium to large game, to a focus on aquatic resources. Regional sites illustrate this shift, though from the point of deposition in central domestic spaces,...
Satellite Remote Sensing of Archaeological Environmental Change in the Chicama Valley (2017)
As global ecological change becomes a pressing contemporary issue, it’s beneficial to also consider how long term land use histories have effected current ecologies. Using imagery from several multispectral remote sensing satellites and field verification of detected sites, I describe how legacies from archaeological occupations impact modern industrial sugarcane production in the Chicama valley. Occupation sites and agricultural systems, both extant and remnant, continue to influence sugarcane...
Saving the Story of Medieval Icelandic Fishery Development: Siglunes as a Case Study (2019)
This is an abstract from the "Accelerating Environmental Change Threats to Cultural Heritage: Serious Challenges, Promising Responses" session, at the 84th annual meeting of the Society for American Archaeology. The combination of deep sea fishing and dried fish production, and its distribution to inland consumers, is a distinctive and largely Nordic contribution to European diet and economy of eventual global impact in the 14th -17th centuries. One of the main questions is how and when this...
Shifting Palaeoeconomies at the Rockshelter Site Madjedbebe, Australia (2018)
The East Alligator River Region has undergone considerable environmental change throughout the Pleistocene and Holocene, with changing sea levels dramatically altering the ecosystems of this region. Current archaeological models for this area indicate that people adapted their economic activities to successfully exploit these shifting environments. Throughout these changes molluscs have played an important role in the economic activities of these groups and often comprise large portions of the...
