In the Late Archaic, projectile point dimensions diminished significantly, displaying patterns that remained until the Early Formative. Nevertheless, during this last period some measurements decreased slightly, and a major change is detected in the haft width of stemmed points. Three alternate hypotheses are proposed for these last changes: 1) the presence of the bow-and-arrow system from the late Archaic onward; 2) the appearance of the bow-and-arrow system from the Early Formative only; 3) the reduction and standardization of spearthrower-darts, without the presence of the bow-and-arrow system until after the Early Formative.

The late Quaternary landscape changes in the Lop Nur region are characterised by cycles between oases and yardang deserts, shaping the extensive aeolian landform. Archaeological evidence suggests humans’ adaptation and resilience to today what are viewed as inhospitable environments since the late Pleistocene by exploiting the diverse range of oasis resources, movement, and encouraging adjacent populations to diversify their subsistence base. Settlement- and regional-scale deterioration of available water resources, affected by environmental and climatic dynamics, caused the eventual abandonment. Periodic occupation and abandonment in the Lop Nur region accompanying oasis-desert/yardang environment cycles provide important lessons for present-day policymakers to contextualise the relationship between human communities and fragile ecosystems. The open-air sites in the Lop Nur region represent the best-preserved oasis-desert civilisation, suffering cultural history losses. We propose the urgent necessity to establish a transdisciplinary database, construct a master chronological framework of settlement, and integrate the culture-nature heritage within the network of the Silk Roads.

In this study, we established a tree-ring width chronology of <em>Pinus armandii</em> Franch in the Funiu Mountains region of central China. Correlation analyses showed that tree radial growths were mainly limited by hydrothermal combination in May–June. The results of the moving correlation analysis further showed that the response relationship between tree growth and relative humidity in May–June (RH<sub>MJ</sub>) was the most stable. This relationship has been reconstructed since 1863. The variance of the reconstructed RH<sub>MJ</sub> was explained by 41.7% (40.6% after adjusting for degrees of freedom). Over the past 158 years, there were 3 wet periods and 4 dry periods. The spectral analysis revealed that the reconstructed RH<sub>MJ</sub> exhibited quasi-periods of 2-4a and 31.6a, and cross-spectrum analysis showed that the reconstructed RH<sub>MJ</sub> may be related to ENSO, PDO, solar activity and the East Asian summer monsoon. The spatial correlation analysis revealed that the reconstructed RH<sub>MJ</sub> accurately depicted the fluctuations in humidity within the Huanghe-Huaihe Plain. Furthermore, the reconstructed RH<sub>MJ</sub> exhibited a strong negative correlation with the sea surface temperature (SST) of the subtropical North Pacific, while it displayed a highly significant positive correlation with the SST of the eastern equatorial Pacific from the previous May to the current April. This also indicated a possible link between humidity fluctuations in the Huanghe-Huaihe Plain and the Pacific internal variability in climate system. Therefore, this research aims to expand and complement the existing meteorological records, providing important reference significance for forest management, agriculture, and animal husbandry.</p></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140615705","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}
