This study, conducted in a wood-rich peatland within PRD of South China, utilized magnetic susceptibility, humification, pollen, and microcharcoal indicators to elucidate substantial environmental and vegetational shifts over the last 6000 cal yr BP, capturing the entire process of wetland formation, development, and disappearance, as well as vegetation transitions from dense forests to open habitats. The <em>Glyptostrobus</em> forests initially developed around 5000 cal yr BP and thrived between 4100 and 2800 cal yr BP. This period coincided with the expansion of freshwater wetlands in the PRD, as strong monsoon-driven freshwater discharge progressively advanced the shoreline seaward, creating numerous freshwater wetlands in the lower reaches of the Pearl River. These newly formed wetlands provided suitable habitats for <em>Glyptostrobus</em> to thrive. Concurrently, the relatively strong Asian Summer Monsoon maintained a warm and wet climate, which was conducive to the prosperity of <em>Glyptostrobus</em> forests. Agricultural activities were identified as the main driver in the degradation and ultimate disappearance of natural <em>Glyptostrobus</em> forest after 3000 cal yr BP.

The entry of millets into the Jianghan Plain likely followed three routes, with the Han River corridor, linking the Nanyang Basin to the Jianghan Plain, being particularly significant. However, this prevalent hypothesis still requires robust archaeobotanical evidence to support it. At the Zhaizishan site, located at the southern end of Han River corridor, flotation analysis identified rice (<em>Oryza sativa</em>), foxtail millet (<em>Setaria italica</em>) and broomcorn millet (<em>Panicum miliaceum</em>), along with 14 types of non-crop remains. The analysis indicated that during the Youziling culture period (5800–5300 BP), millets were already present near the Jianghan Plain but less prominent within the crop assemblage. However, its significance increased during the Qujialing culture period (5300–4500 BP), although rice continued to be dominant. During the Shijiahe culture period (4500–4200 BP), the importance of millets may have further increased. The discovery of millets at the Zhaizishan site during the Youziling culture period strongly supports the theory that the Han River corridor served as a route for the southward spread of millets, no later than 5300 years ago. In addition, by comparing crop structures at the Zhaizishan and Qujialing sites, we found that natural and cultural factors both contributed to the increasing importance of millets within the agricultural system. Additionally, the sloped terrain would have driven ancient humans to cultivate more millet.

Even though the Indian monsoon system is a major component of the global climate and hydrological system that gets severely impacted by other climate variables and natural climate forcings, its responses and linkages with different climate parameters remain poorly understood. The Bay of Bengal (BoB), a prominent sub-basin of the Northern Indian Ocean, receives rainfall mainly from the Indian Summer Monsoon (ISM) and partly from the Northeast Monsoon (NEM). Further, the basin receives a large quantity of fluvial sediment discharges from both the Himalayan and peninsular rivers.

Since their 19th-century discovery in Southeast Asia, interdisciplinary approaches (typological, zooarchaeological, and environmental analyses) have established their significance in deciphering prehistoric subsistence patterns and past environmental changes. Shell midden sites are mainly distributed in coastal and riverine-lacustrine areas, with shellfish species categorized as marine or freshwater. The chronological framework of shell midden sites is as follows: during the Late Paleolithic period (approximately 25,000–10,000 yr BP), shell midden sites appeared in inland areas; in the Early to Middle Neolithic period (approximately 9000–5000 yr BP), following the end of the Last Glacial Maximum (LGM, approximately 26,500–19,000 yr BP), marine shell midden sites proliferated in coastal areas. The peak of shell midden sites occurred during the Holocene Climatic Optimum (approximately 8000–5000 yr BP), with climate change, the development of agriculture, and other factors, shell midden sites gradually declined, continuing into the Late Bronze Age (approximately 5000–3000 yr BP). Although previous studies have revealed that climate change, sea-level fluctuations, and shifts in human subsistence strategies contributed to these changes, a comprehensive understanding of when and why shellfish began and ceased to be a primary food source is still lacking. This study analyzes the spatio-temporal distribution of shell midden sites over China and explores how climate and sea-level changes influenced the initiation and cessation of shellfish consumption as a main food source. The findings indicate that climate and sea-level fluctuations significantly affected the distribution of shellfish resources, thus influencing ancient human subsistence strategies and driving the transition to agricultural and pastoral economies.

The western Indian sector of the Southern Ocean, characterized by dynamic interactions among water masses, wind patterns, and biogeochemical processes, is particularly influenced by the Subtropical Front (STF)—a critical boundary separating colder, less saline southern waters from warmer, saltier northern waters. In this study, we examined a marine sedimentary core from the southern Agulhas Plateau located in the Agulhas Return Current (ARC) region, to reconstruct oceanographic conditions over the past ∼350 ka using planktic foraminiferal relative abundance and stable oxygen isotope (δ¹⁸O) data. Our findings reveal that glacial periods (MIS 4 and 2) were marked by increased productivity, likely driven by intensified Southern Hemisphere westerlies and a northward-shifted STF, facilitating nutrient-rich Sub-Antarctic Surface Water (SASW) influx. In contrast, glacial periods MIS 8 and MIS 6 showed reduced productivity, linked to an increase in the transport of warm, nutrient-poor Subtropical Surface Waters (STSW) through the Agulhas Return Current to the region. The MIS 6/5 transition (Termination II) marked a significant shift, characterized by the replacement of warmer, stratified, nutrient-poor waters with colder, well-mixed, nutrient-rich conditions. Evidence of thermocline deepening during warm periods as well as during MIS 8 and MIS 6 underscores enhanced stratification. Furthermore, variability in Agulhas Return Current strength across glacial and interglacial phases reflects the sensitivity of tropical-subtropical assemblage transport to STF positioning. These results underscore the intricate interactions between ocean circulation, frontal dynamics, and regional hydrography in shaping past marine environments, and offer critical insights into the palaeoceanographic evolution of the southwest Indian Ocean and its broader climatic implications.</div></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":"740 ","pages":"Article 109894"},"PeriodicalIF":1.9,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144366323","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}
