Annually-Resolved Environmental proxies in the Great Lakes Region, 14 ka to 10 ka BP: A Time of Paleo-Indian Hunters and Megafauna Extinction (2016)
The last deglaciation was characterized by numerous abrupt climate shifts including the extended Bølling and Allerød warm periods and the Preboreal, Younger Dryas, Older Dryas and Intra-Allerød cold periods, which caused loss of stability across the periglacial landscapes of the Great Lakes region. To date, assessing the possible impact of abrupt late glacial environmental change in this area has been limited by paucity of high-resolution environmental proxies that can be compared to the...

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 (Global and SE Asia) (2018)
We have developed millennial length reconstructions of regional hydroclimate using multiple collections of tree cores from throughout Southeast Asia. Several published records of seasonal hydroclimate from Vietnamese cypress represent the most robust and well-replicated tree ring records from the global tropics, and allow for detailed analyses of the regional hydroclimate for multiple seasons. We demonstrate zonal changes in the mean climate over the past millennium with strong linkages to the...
Climatic Changes and Ceramics during the Terminal Classic at Chichén Itzá. (2016)
According to the ceramic evidence that came out of the Chichen Itzá sinkholes or "cenotes" it seems the ancient Maya offered into these wells important quantities of pots and very unique ceramic vessels within a very specific period of time, and under very specific situations. The evidence indicates that most of the ritual activity occurred approximately between AD 900-1100, a time that coincides chronologically with the end of the Terminal Classic Period, the rise and subsequent abandonment of...
Creating a Discovery Model for Submerged Late Pleistocene and Early Holocene Sites on the Northern Gulf Coast (2016)
Between 13,000 and 12,300 BP, sea levels in the Gulf of Mexico increased rapidly. For the next 2,300 years, however, sea levels both rose and fell by centimeters per year, producing significant shoreline movement observable within a human lifetime. Because of continental shelf’s topography, however, shorelines in different areas did not shift at the same rate. Areas with minimal movement would have seemed more stable and attractive for repeated occupations over generations. This paper models of...

Equifinalities and the Limits of Soil, Ecology, and Climate Knowledge in Maya History (2016)
We read history to understand the present and possible future worlds, but each situation that arises in time is unique. This paradox of history also fits natural science brought to bear on archaeology because often equifinality prevails, meaning there are several paths to the same ends we see in landscapes. These complicate our interpretations, both delightfully and disturbingly. Here, we address both the agronomic and climatic capriciousness of the variegated Maya puzzle. We consider terrace,...
Freshwater Availability and Prehistoric Settlement Patterns on California’s Northern Channel Islands (2015)
An important variable that influenced prehistoric human settlement patterns on California’s northern Channel Islands was the availability of freshwater. Existing models of settlement use watershed size as a proxy for water availability. However, in semi-arid regions, this approach has limitations because ephemeral streams common in these environments may lose much or all of their flow to groundwater. We have developed a hydrological model that incorporates measured and modeled...
Long and Continuous Record of Climate and Environmental Change from Speleothems of the Cape Floral Region of Southern South Africa (2015)
South African climate is determined by the alternating influence of subtropical trade-winds bringing rainfall to the east coast during summer and temperate westerlies causing rainfall in the south-west during winter. High growth season temperatures favor C4 grasses in the summer rainfall region whereas C3 grasses dominate the winter rainfall region. Pinnacle Point on the central south coast has mixed summer-winter rainfall and C3-C4 vegetation. Millennial and longer time-scale changes in...

Multidisciplinary Reconstruction of Interactive Change in Holocene Treeline, Paleoclimate,and High Altitude Hunting Systems in Rocky Mountain National Park, Colorado (2015)
More than eighty high altitude game drives are known along north central Colorado’s continental divide, but until recently there has been limited understanding of the interactive effect of cyclical climate and ecosystem change on Holocene alpine tundra hunting systems. University of Northern Colorado researchers, after fifteen years of high altitude archaeological and paleoclimate research, have produced an early phase reconstruction of game drive use and elevation-specific environmental zone...
Paleoclimate data and behavioral change in the highlands of Papua New Guinea (2017)
Climate variability generates both opportunities and limitations for subsistence strategies, as well as related settlement patterns and technologies. While not the only driver of behavioral change, climate is a critical force in shaping patterns of past behavior. This paper presents the results of lithic analysis of three sites from the Eastern Highlands of Papua New Guinea that span 20,000 years of occupation. Additionally, the findings from a summed probability distribution analysis of...
A Paleoclimate model of Neanderthal landscape-use during the last interglacial (2016)
Obstacles to our understanding of Neanderthal (Homo neanderthalensis) land-use patterns during the Last Interglacial (130kya-116kya, Marine Isotope Stage 5e) include not only the scarcity of sites in Europe but also a lack of knowing what the landscape may have looked like during this time. This research explores the influence of climate and seasonal variability on Neanderthal land-use. Recently developed global climate models are capable of simulating past climate variables (e.g., precipitation...

Petroglyphs as time markers for Pleistocene occupation of the Great Basin (2017)
The association of cupules and pit and groove petroglyphs is possibly the oldest form of "rock art" in the Americas as evidenced in the northern Great Basin. Recant methods of dating petroglyphs, made possible by unusual paleoclimatic circumstances, have resulted in what may be the identification of the ‘North America’s oldest petroglyphs." Three sites located on the shores of ancient Pleistocene Lakes, two at Lake Lahontan in northern Nevada and one at Long Lake in southern Oregon, have given...
POLLEN AND CHARCOAL ANALYSIS OF STRATIGRAPHIC SAMPLES FROM TAPIA ARROYO AND RIO PUERCO, NEW MEXICO (2002)
Twenty four stratigraphic samples were examined for pollen and charcoal from two arroyos in northern New Mexico. This study was designed as a pilot study to examine the possibility of sampling these locations at closer intervals to refine any paleoenvironmental interpretations deemed possible through this analysis. Pollen analysis provides a look at vegetation, while charcoal counts provide a means of assessing fire history. In addition, an archaeoclimatic model was examined to provide...
Prehistoric Hookworm and the Peopling of the Americas: Enhancing Theories Based on Paleoclimate Models and Pathogens (2023)
This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology. Humans brought many things with them when they came to the Americas. This study focuses on hookworms and domesticated dogs to revise, constrain, or enhance theoretical models of when and how humans first came to the Americas. The hookworm life cycle is critically dependent upon the environmental conditions and proximity to suitable hosts. Its eggs leave...
Productivity in a human context: creating and applying proxies relevant to Chicama Valley archaeology. (2017)
El Niño-related changes in marine and terrestrial productivity impacted Chicama residents in several ways, including altering available marine species, soil productivity, and by extension, the technological and economic innovations necessary to adapt. The combination of marine and terrestrial resources were central to the economy of people living in the Chicama Valley throughout the Holocene. Estimates of El Niño’s effects on past marine productivity typically rely on open ocean proxies distant...

Stable carbon and oxygen isotopes in faunal tooth enamel from Boomplaas and Nelson Bay Cave record Late Pleistocene/Holocene environments in the southern Cape, South Africa (2015)
The Pleistocene palaeoclimates and palaeoenvironments of southernmost Africa are important in both global climate studies and studies of human evolution, but remain poorly documented through time and space. In order to contribute to this project, we have analysed δ13C and δ18O in approximately 350 samples of faunal tooth enamel from Boomplaas Cave and Nelson Bay Cave, in the southern Cape, South Africa. The Boomplaas samples span the last ca. 70 kya, and show fluctuations in δ13C indicating...
