Our results show that land snails have a dietary preference for C₃ plants which have dominated the studied area since 19 ka. Thus, their shell δ¹³C_s could be used to investigate the δ¹³C variations of C₃ plants and precipitation changes. The highest δ¹³C_s values with the smallest standard deviation (SD) reflect the intense water stress experienced by C₃ plants during the Last Glacial Maximum (LGM). In the last deglaciation, the δ¹³C_s values decreased gradually, indicating increased East Asian summer monsoon (EASM) precipitation. The lowest δ¹³C_s values occurred in the early-middle Holocene, suggesting that abundant precipitation enhanced favorable conditions for C₃ plants. Thereafter, the δ¹³C_s values increased again, which may be linked to elevated water stress for C₃ plants in the mid-late Holocene. Altogether, our study implied that there is a ∼300 mm mean increase of precipitation from the LGM to the early-middle Holocene on the southern CLP. Notably, the deglacial warming preceded the onset of EASM precipitation increase by ∼2 ka, as indicated by the fossil snail count and their δ¹³C_s values, and this decoupled phenomenon is more robust and convincing compared with previous work, because it is derived from the exact same geological archive.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"356 ","pages":"Article 109312"},"PeriodicalIF":3.2,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143609465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the scarcity of Holocene paleoclimate reconstructions in this region impedes analysis of potential climate-human interactions. Furthermore, current hydroclimatic scenarios for Mesopotamia are predominantly based on oxygen isotope (δ¹⁸O) proxy records from the eastern Mediterranean, whereas the paleoclimatic significance of δ¹⁸O remains debated. Here, we present a Holocene stalagmite multi-proxy record from Shalaii Cave in northern Mesopotamia. Based on stable isotope, trace element and strontium isotope measurements, our new Shalaii Cave record suggests that long-term changes in δ¹⁸O were influenced by multiple factors, such as δ¹⁸O changes of the source of moisture, amount and seasonality of rainfall. The Shalaii Cave trace element and strontium isotope records indicate rather dry conditions during the early Holocene and wettest conditions during the mid-Holocene. This mid-Holocene hydroclimate optimum at Shalaii Cave is in good agreement with other non-isotopic records from SW-Asia, such as pollen evidence for concurrent rapid forest expansion and peaking lake levels. The mid-Holocene hydroclimatic optimum is most likely related to an increase in the amount of spring precipitation related to the remote influence of the Indian summer monsoon (desert-monsoon mechanism) and spring insolation-driven weakening of the Arabian anticyclone. In particular the latter northward migration of the Arabian anticyclone in spring promoted a longer spring rainfall season.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"356 ","pages":"Article 109286"},"PeriodicalIF":3.2,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143609464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We use principal component analysis of first-order reversal curves to characterise the magnetic minerals incorporated into a 33 kyr flowstone record from Aotearoa New Zealand. Three end members (EMs) represent (1) a component with a broad spectrum of grain sizes, similar to that found in the overlying soil (EM1); (2) a coarse multi-domain component, with grains ranging up to several hundred microns (EM2); and (3) a fine, single-domain to vortex component (EM3). We interpret EM1 and especially EM2 as proxies for cave stream flooding and EM3 as a proxy for soil erodibility and transport through infiltration or possibly aeolian processes. We find increased soil erodibility during the period 30-20 kyr BP, corresponding to the extended Last Glacial Maximum (eLGM). Flooding frequency is high during the periods 27-25 kyr BP and 9-0 kyr BP. eLGM flooding episodes as recorded in the flowstone may be enhanced by the deposition of the Kawakawa/Oruanui tephra, providing a rich source of magnetic material.

They appeared very early in the Yangtze Delta region and continued to develop into diverse forms and structures, becoming essential parts of the expanding rice-farming economies and stimulating great social structural changes in prehistoric and historic times. This paper examines the physical environmental conditions, field construction and modification, and water management of prehistoric rice fields that were excavated recently in the Yangtze Delta and Huai River regions through geoarchaeological surveys of excavated fields and detailed micromorphological and sedimentation analyses of collected samples. We sketch out the broad developmental trajectory of rice fields from the preliminary field modification to systematic landscape transformation during the intensification process of rice farming with macro-scale environmental evidence and micro-morphological evidence. Our results show that alongside the macro-scale morphological changes of the rice fields with a noticeable trend of size increase over the long-term period, are more intensive field management practices as evidenced by the increasing presence of diagnostic soil micromorphological features such as concentric clay textural features and redoximorphic features caused by frequent wet-dry alternations from more sophisticated manipulation of field hydrologies and soils. We also compare the similarities and differences in the scale, structure, and soil and environmental conditions of rice fields in different regions and discuss their significance to understand different intensification processes and interactions with rice-farming societies in prehistoric Yangtze Delta and Huai River regions. We suggest that constrained by regional soil, hydrological and topographic differences, these regions might have undergone intensification and extensification processes. Typically, small fields or field-like structures in the Upper-and-Middle Huai River and around Taihu-Lake regions remained unchanged for a relatively long time until the late Majiabang when systematic transformation of local environments for large-scale rice farming began. This is in contrast with the Ningshao Plain where Hemudu-period rice fields were without field bunds and other facilities. However, the divergent regional trends in the scale and practices of rice farming around the Taihu Lake and Ningshao Plain regions might have converged during the Liangzhu period, leading to a significant expansion in rice fields, as vividly represented by the Shi'ao and Maoshan examples discussed in our paper.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"356 ","pages":"Article 109293"},"PeriodicalIF":3.2,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143600512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Today, kākāpō only survive on managed predator-free sanctuaries (&lt;250 individuals), and rarely breed except during mast events of native rimu trees (<em>Dacrydium cupressinum</em>). Here, we review NZ's Late-Quaternary fossil record in relation to palaeovegetation, and determine whether it can be used to identify the past habitats and distribution of kākāpō. First, we describe the distribution of kākāpō fossils from c. 25ka until the present and the former habitat breadth of kākāpō. Second, by comparing the abundance of kākāpō fossils to those of similar-sized landbirds in each site, we identify how past kākāpō abundance was affected by habitat type. Although we identify that kākāpō exhibit strong taphonomic biases, we show that kākāpō are the fourth-most common bird taxon in NZ's late-Quaternary deposits (1351 Minimum Number of Individuals from 274 sites), and occupied all forests and adjacent habitats, on the NZ mainland prior to human settlement ca. 0.8 ka. However, we find little evidence that kākāpō occupied semi-arid shrublands, the high alpine zone, or most grassland/shrublands during glacial periods. Further, kākāpō were most abundant in humid, high precipitation forests, were rarest in drought-prone, low-rainfall scrub/forests, and were common in many rimu-free habitats. We also determine that contemporary kākāpō occupy a small proportion of their optimal habitat range.

Accurate dating of fluvial terraces, which record both aggradation and incision processes, is essential for understanding the evolution of drainage systems. However, conventional dating methods such as radiocarbon (¹⁴C), optically stimulated luminescence (OSL), and cosmogenic radionuclide (CRN) techniques face limitations, particularly for terraces outside their optimal ranges or those with complex burial histories. This study introduces a novel approach based on the recoil loss of ²³⁴U from particle surfaces following fragmentation from bedrock, enabling the dating of silt terrace sediments without the need for well-buried or sorted samples. We apply this approach to terrace sequences along the Lancang and Jinsha rivers on the southeastern fringe of the Tibetan Plateau, an area that has been extensively studied for its geomorphology and sedimentology to investigate fluvial responses to tectonic and climatic drivers. Our results reveal a consistent decrease in ²³⁴U/²³⁸U ratios with increasing terrace height, approaching equilibrium values. The deposition ages derived from this method closely align with K-feldspar post-infrared infrared stimulated luminescence (pIRIR) ages from the Lancang River and show a positive correlation with electron spin resonance (ESR) ages from the Jinsha River. Based on the terrace ages presented here, we estimate long-term incision rates of 0.46 mm/yr for the Lancang River and 0.31 mm/yr for the Jinsha River since the middle Pleistocene. These findings underscore the potential of the uranium comminution age method as an effective tool for dating fluvial terrace deposits, providing an additional dating method to conventional dating techniques.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"356 ","pages":"Article 109264"},"PeriodicalIF":3.2,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143629084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Shark Lake has a hydrologically open configuration, with water isotope values that mirror annual mean precipitation, and contains a continuous sediment sequence consisting largely of authigenic carbonate minerals precipitated from the water column. The sediment δ¹⁸O record exhibits a shift from lower to higher-than-average δ¹⁸O values from the middle to late Holocene circa 4,100 calendar years before present (yr BP). This transition generally aligns with hypothesized transformations in atmospheric circulation that ostensibly led to reduced winter precipitation in northwestern North America and heightened aridity in the southwest during the late Holocene. Monte Carlo cross-correlation analysis demonstrates that other precipitation δ¹⁸O records from the Pacific Northwest have a significant positive correlation with the Shark Lake record, in contrast with records from the southern Rocky Mountains and central/eastern North America, which have a negative correlation with the Shark Lake record and others from the Northwest. We apply the previously established strong relationship between atmospheric circulation associated with the Pacific North American Pattern (PNA) and precipitation isotope values across North America to explain the marked coherency in precipitation δ¹⁸O reconstructions. Collectively, the paleo-records suggest a middle to late Holocene transition in the mean state of atmospheric circulation over North America from one similar to the negative phase of the PNA to one comparable to the positive PNA phase, in response to non-linear changes in ocean-atmosphere circulation driven by ice sheet decay and insolation forcing. This shift had substantial impacts on the source and isotopic composition of air masses traversing the continent and their interplay with circulation from the Gulf of Mexico as well as the seasonal amount and distributions of precipitation.
