“…The MLT occurred during a period of extreme droughts associated with the Medieval Climatic Anomaly (1150-600 cal BP; Kennett 2005;Jones et al 1999;Jones and Schwitalla 2008;Raab and Larson 1997;Stine 1994;Yatsko 2000) that were felt throughout the American Southwest (Jones et al 1999;Jones and Schwitalla 2008;Bocinsky and Kohler 2014). Osteological data from the Santa Barbara Channel region reveal peaks in health problems and violence (Lambert and Walker 1991;Walker 1989;Walker and Lambert 1989;Lambert 1993) associated with increasing sedentism and diminishing supplies of fresh water and terrestrial foods.…”

Using targeted survey, excavation, and radiocarbon dating, we assess the extent to which human settlement patterns on California's northern Channel Islands fit predictions arising from the ideal free distribution (IFD): (1) people first established and expanded permanent settlements in the regions ranked high for environmental resource suitability; (2) as population grew, they settled in progressively lower ranked habitats; and (3) changes in the archaeological record associated with high population levels such as increases in faunal diversity and evenness in high-ranked habitats are coincident with the expansion to other areas. On Santa Rosa Island, the early permanent settlements were located in both high-and middle-ranked locations, with the most extensive settlement at the highest ranked locations and only isolated sites elsewhere. Settlement at a low-ranked habitat was confined to the late Holocene (after 3600 cal BP). Drought influenced the relative rank of different locations, which is an example of climate adding a temporal dimension to the model that episodically stimulated population movement and habitat abandonment. Because the IFD includes a wide range of cultural and environmental variables, it has the potential to be a central model for guiding archaeological analysis and targeted field research.

“…The SKOPE project, studying human-environment interactions in the southwestern United States (e.g., Bocinsky and Kohler, 2014), is using Neotoma as a platform for accessing paleoecological data and, in the process, discovering data corrections and additional records for addition to Neotoma. PalEON, interested in understanding climate-driven vegetation dynamics over the last 2000 yr, has been discovering new records for addition to Neotoma and updating age models as part of its development of the STEPPS pollenvegetation model Goring et al, 2016;Kujawa et al, 2016).…”

The Neotoma Paleoecology Database is a community-curated data resource that supports interdisciplinary global change research by enabling broad-scale studies of taxon and community diversity, distributions, and dynamics during the large environmental changes of the past. By consolidating many kinds of data into a common repository, Neotoma lowers costs of paleodata management, makes paleoecological data openly available, and offers a high-quality, curated resource. Neotoma's distributed scientific governance model is flexible and scalable, with many open pathways for participation by new members, data contributors, stewards, and research communities. The Neotoma data model supports, or can be extended to support, any kind of paleoecological or paleoenvironmental data from sedimentary archives. Data additions to Neotoma are growing and now include >3.8 million observations, >17,000 datasets, and >9200 sites. Dataset types currently include fossil pollen, vertebrates, diatoms, ostracodes, macroinvertebrates, plant macrofossils, insects, testate amoebae, geochronological data, and the recently added organic biomarkers, stable isotopes, and specimen-level data. Multiple avenues exist to obtain Neotoma data, including the Explorer map-based interface, an application programming interface, the neotoma R package, and digital object identifiers. As the volume and variety of scientific data grow, community-curated data resources such as Neotoma have become foundational infrastructure for big data science.

“…First, building accurate understandings of climatic impacts on human societies in the past requires paleoclimate reconstructions at spatial and temporal scales relevant to human experience (31). A major challenge thus lies in downscaling: translating regional or even global climatic records into local records.…”

“…For this and another densely occupied portion of the Pueblo world along the northern Rio Grande of New Mexico, water-year precipitation and growing degree days have recently been retrodicted using a method from quantitative genomics to choose the best combinations of tree-ring chronologies as predictors (31). Thresholding these reconstructions at the thermal and moisture requirements for maize, locations where it could grow without irrigation for the last 2,000 y were mapped, helping explain many population movements in the Pueblo region.…”

By documenting how humans adapted to changes in their environment that are often much greater than those experienced in the instrumental record, archaeology provides our only deep-time laboratory for highlighting the circumstances under which humans managed or failed to find to adaptive solutions to changing climate, not just over a few generations but over the longue durée. Patterning between climatemediated environmental change and change in human societies has, however, been murky because of low spatial and temporal resolution in available datasets, and because of failure to model the effects of climate change on local resources important to human societies. In this paper we review recent advances in computational modeling that, in conjunction with improving data, address these limitations. These advances include network analysis, niche and species distribution modeling, and agent-based modeling. These studies demonstrate the utility of deep-time modeling for calibrating our understanding of how climate is influencing societies today and may in the future.climate change | archaeology | computational modeling | agent-based modeling
