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 (<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.

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.

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 δ<sup>18</sup>O record exhibits a shift from lower to higher-than-average δ<sup>18</sup>O 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.

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 δ<sup>18</sup>O 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.

In this study, we investigate calcite stalagmites that form under evaporative conditions near cave entrances in areas that receive low precipitation (∼250 mm/year). Such stalagmites have yet to be explored in environmental magnetism, and are typically avoided in paleoclimatology due to complications in their geochemistry. Proxies based on detrital inclusions, such as speleothem palynology, have, however, proven favorable in these conditions. Here we report the first combination of speleothem magnetism with published pollen and charcoal records from two stalagmites formed over the last ∼2400 years at Webbs Cave, located on the ∼230,000 km<sup>2</sup> Nullarbor Plain in southern Australia. Rock magnetic experiments were performed using anhysteretic and isothermal remnant magnetizations, hysteresis loops, and low-temperature remanence measurement to investigate the concentration, phases, and grain size of the magnetic mineral assemblage. Analysis of detrital particles and speleothem porosity was undertaken using x-ray microtomography. The magnetic mineralogy of both stalagmites is typical of stalagmites globally in being dominated by magnetite or maghemite with dominant grain size distributions in the superparamagnetic to single-domain range, which occurs alongside goethite and potentially hematite. Both the low and high coercivity fractions co-vary and are consistent with local soils, furthering the link between stalagmite magnetism and pedogenesis. However, rather than increasing with precipitation, we infer that magnetic particle concentrations can increase during drier climates, based on correlations to the stalagmite pollen records. This likely results from increased detritus in available drip waters, along with increased deposition of localized cave dust during (dry) periods of slow stalagmite growth. While the magnetic particles in near-entrance stalagmites may derive from multiple transport modes, their local soil provenience forms the main control on their magnetic properties.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"356 ","pages":"Article 109290"},"PeriodicalIF":3.2,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143563781","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}

Here we used multi-proxy data—including dry bulk density, loss on ignition, plant macrofossils, diatoms, stable oxygen isotopes (δ<sup>18</sup>O<sub>bulk</sub>) and C/N ratios—to understand the response of peatland vegetation and carbon accumulation to hydroclimate changes from two peat cores of a bamboo-sedge-<em>Sphagnum</em> peatland (27.621°N, 98.590°E; 3037 m asl) on the southern Hengduan Mountains at the southeastern edge of the Tibetan Plateau. The cores were dated by AMS <sup>14</sup>C radiocarbon dates with a basal age of 4500 cal yr BP. The peatland was formed on an abandoned floodplain, as evidenced by the gravel and biotite at the base, likely in response to the weakening South Asian summer monsoon (SASM) in the late Holocene. From 4500 to 1300 cal yr BP, the gradual increase in the δ<sup>18</sup>O<sub>bulk</sub> values—reflecting less intense convection in monsoon source regions and locally at time—indicates a continued weakening SASM and drying trend during the late Holocene. Furthermore, the low apparent carbon accumulation rate (aCAR) of 4 g C m<sup>−2</sup> yr<sup>−1</sup> during that time is likely due to the great decomposition of dominant bamboo-derived organic matter. The higher δ<sup>18</sup>O<sub>bulk</sub> value at 1300-800 cal yr BP—possibly corresponding to the “Medieval Climate Anomaly” (MCA)—than the Little Ice Age (LIA) at 800-200 cal yr BP indicates a drier MCA, supported also by high charcoal content, low diatom abundance and high C/N ratios at our sites. The large difference of 8‰ in the δ<sup>18</sup>O<sub>bulk</sub> values between the MCA and LIA suggests that local hydrological processes might have amplified the effect of monsoon-mediated hydroclimate on δ<sup>18</sup>O variations. The higher aCAR during the MCA at 15 and 28 g C m<sup>−2</sup> yr<sup>−1</sup> for two cores than during the LIA at 13 and 18 g C m<sup>−2</sup> yr<sup>−1</sup> suggests that the relatively dry climate during the MCA promotes plant production and peat accumulation in this terrestrialized, still-wet and then sedge-dominated peatland.

Using a multi-scale, interdisciplinary approach - combining detailed field investigations (stratigraphic, geomorphological, structural, and paleoseismological analyses), tephrochronological and OSL dating, and reassessment of macroseismic intensity distribution from archival sources - this study identifies a possible source for these earthquakes. It corresponds to a ∼45 km normal fault system composed by two main branches (Eastern Calore Fault and Western Calore Fault) with primary segments trending E-W to ESE-WNW and dipping N- to NNE. Segments extend along the southern border of both eastern and western Calore River sub-basins and are partially connected by NNW-SSE to N-S trending, east-dipping, transfer zone fault splays.
