Here we present Bayesian analysis for radiocarbon dates from Moche cultural contexts from the north coast of Peru with the aim to understand the duration of the phenomenon and to compile all known dates in a single location for future analysis and use. The analysis demonstrates that the long-standing Moche ceramic sequence does not provide a perfect proxy for tracking the timing of all social interactions. However, our results show general agreement with traditional relative Moche chronologies. Finally, our study shows that Moche was a shorter cultural phenomenon than has been previously argued, with the current data indicating that it began between the late 4th and early 6th centuries CE and lasted until the 9th century CE.</p></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1040618224001642/pdfft?md5=d4e5947c5e138f8e5d25cd5115fd9339&pid=1-s2.0-S1040618224001642-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142172637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The LIP is often characterized as a unit, but major developments took place within this long period, including diasporic migrations and the new colonization of some regions, demographic change, intensified conflict, large-scale adverse climate episodes, and changes associated with the onset of Inca expansion. Here we make a preliminary attempt to clarify the chronology of these developments. A database of published and new radiocarbon dates is compiled for the south-central highlands and coastal valleys in order to model overall and subregional demographic trends using an updated “dates-as-data” cumulative kernel density estimate (CKDE) approach, and to examine specific LIP phenomena in two subregions. Our results indicate major demographic change including 1) substantial population growth beginning in the 13th century, 2) a marked 14th-century population surge in most, but not all, subregions included here, 3) evidence of population decline in several subregions during the same intervals when neighboring populations are expanding. Population growth was associated with intensified violence and increased physiological stress in the upper Nasca drainage. In the altiplano of Peru and Bolivia, population growth accompanied the rise of defensive hillforts and monumental cemeteries. Our date models also indicate a more complicated terminal LIP in the altiplano, with the height of classically “LIP” societies overlapping with early evidence for imperial Inca presence. This paper highlights the ways that more refined chronology can make advances in our understanding of a turbulent post-collapse era in the Andes.</p></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135762278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We identify patterns consistent with biases stemming from disproportionate research attention, regional and intrasite sampling methodologies, and taphonomy that may be hampering our study of middle Holocene foragers. Further confounding our understanding of foragers during this period are reports of middle Holocene radiocarbon gaps attributed to population decline across South America in response to climate-induced scarcity of freshwater and other resources.

Kernel Density Estimate (KDE) summaries of Bayesian phase models demonstrate the following aspects of regional cultural dynamics: the earliest settlements began in the Preceramic ca. 6000 BCE and are found on the coast; the Paracas culture was established ca. 900 BCE and cultural development was first focused in the north and then spread south; a reverse direction of cultural influence is found during the Nasca culture when innovation began in the south and spread north; an early mixture of Late Nasca/local Loro culture is found in Nasca (510–720 CE) followed by the spread of Loro elsewhere and the establishment of intrusive highland Wari colonies that peaked in the mid-9th century CE; and the Late Intermediate Period was variable throughout the region in terms of timing and duration, reflecting a turbulent period. The results of the study reveal strong temporal overlap in the ceramic styles indicating they are not purely sequential and consequently are inadequate as chronological markers on a regional level.

We calibrate dates with a bespoke calibration curve mixture specific to Machu Picchu.

The primary goal is to assess the suitability of various proxies as representatives of modern vegetation, environmental and climatic conditions. The collected data indicate significant variations in the composition and density of pollen in response to climate-induced and anthropogenic ecological changes throughout the northwest India transect. The palynological studies from eastern Rajasthan shows high forest elements in comparison to western Haryana and western Uttar Pradesh. In addition, the palynological data was juxtaposed with other biotic proxies such as diatom and isotopic studies, along with geochemical proxies and paleomagnetic data of the surface lake sediments. The presence of marker pollen taxa including Cerealia type Poaceae, Chenopodiaceae, and Brassicaceae, allows for distinct recognition of anthropogenic activities throughout the whole transect. The diversity and distribution of diatoms also support the palynological data in response to climate-induced and anthropogenic ecological changes. Furthermore, grain size, geochemistry (TOC/TN ratio with stable carbon isotope), and magnetic susceptibility data offer crucial insights about the sediment's depositional settings and general mineralogical composition. Stable carbon isotope data shows C₃ dominance in relatively humid areas and C₄ dominance in semi-arid areas, suggesting climate-driven control over sediment organic matter composition. Canonical correspondence analysis (CCA) indicates that biotic variables (pollen, diatom, stable isotopic composition) are significantly controlled by modern precipitation and temperature. Redundancy analysis reveals a significant influence of current average temperature and precipitation on major element oxide variations in surface lake sediments. Therefore, we propose using palynological, stable carbon isotope, diatom data, along with grain size, environmental magnetism, and geochemistry, to establish a multiproxy modern analogue for quantitative palaeoclimatic reconstructions. As a result, this study provides the first modern analogues from a climate-sensitive region that separates the area under ISM influence from an area with meager precipitation in western India.</p></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142173065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
