This vegetation formed the Pleistocene mammoth steppe, which provided a habitat for large herbivores like mammoths (<em>Mammuthus primigenius</em>) and steppe bison (<em>Bison priscus</em>). In this study, we analyzed the DNA sequences of well-preserved plant material from the intestinal tract of the frozen mummy of an extinct steppe bison discovered in the Kolyma Lowland, Northeastern Russia in 2009. Radiocarbon dating placed the specimen at &gt;48 kyr. We leveraged genome-wide and skimmed genome accessions to maximize the retrieval of sequenced reads for identification. In line with macrofossil evidence, we identified alkali grass (<em>Puccinellia</em>), indicating high salinity, and Larch (<em>Larix</em>) in the DNA data of the steppe bison sample. The occurrence of larch north of the current tree line indicates warm temperatures during the growing season. Additionally, we confirmed the presence of plant genera typically associated with steppes and productive meadows under open and arid soil conditions such as <em>Artemisia</em>, <em>Tanacetum</em>, <em>Koeleria, Festuca</em>, <em>Puccinellia, Taraxacum, Alopecurus,</em> and <em>Poa</em>, while <em>Phippsia</em> suggests high soil water content, at least locally. We also attempted to infer the likely most closely related species for each genus. The most abundant authenticated genera, <em>Artemisia</em> and <em>Puccinellia</em>, align with their known prevalence in the mammoth steppe, reflecting broader environmental signals beyond the steppe bison's diet. Hence, the use of metagenomic approaches in combination with comprehensive reference databases offered insights into steppe bison diet, allowed us to obtain a more detailed view of the mammoth steppe vegetation, and provided extended interpretations of soil conditions.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"369 ","pages":"Article 109604"},"PeriodicalIF":3.3,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144932862","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}

Some are active seasonally, whereas others are dry and preserve up to several meters of sedimentary deposits. These deposits feature a variety of evaporite minerals, including the hydrated mineral gypsum (CaSO₄⋅2H₂O). The isotopic composition of gypsum hydration water preserves the δ¹⁸O and δD of paleolake water at the time of gypsum formation. This provides a way to understand the hydrologic balance in a part of the world where it is typically very difficult to obtain any paleoclimate records. We present paleohydrological records from two dry playas (Karsandi, Khajuwala) and one active playa (Lunkaransar) in the Thar Desert using the oxygen and hydrogen isotopic composition of gypsum hydration water. We present a theoretical model to explain differences in how the gypsum records water isotopic composition from perennial playas (consistent paleoclimate recorders) as opposed to seasonally fed or ephemeral playas (that reflect evaporated meteoric water inconsistently). Results suggest that enhanced direct precipitation, with associated higher groundwater and possibly fluvial sources, maintained active playa lake basins in the central Thar Desert for the Early through Middle Holocene. We also examine δ³⁴S_SO4, δ¹⁸O_SO4, and ⁸⁷Sr/⁸⁶Sr of the gypsum sulfate to explore the source and evolution of solutes in the Thar Desert playas. Results indicate that seasalt aerosols likely accumulated in aeolian sands during glacial dry periods and concentrated in playa deposits once a threshold level of moisture was reached in the Early Holocene. By the Late Holocene, after c. 4.4 ka BP, these water sources diminished and some playas were again covered by aeolian deposits.

This study reconstructs at a high temporal resolution the evolution of the phytoplankton structure and biological pump efficiency over the past 1960 kyr on the basis of the biomarker analyses of a long sediment core from the Ocean Drilling Project (ODP) Site 1170 in the South Tasman Sea. The Mid-Pleistocene Transition (MPT) notably enhanced regional phytoplankton abundance and biological pump efficiency. During the MPT, surface phytoplankton structure was strongly influenced by global cooling and increased Fe input from intensified terrestrial weathering, leading to pronounced phytoplankton blooms aligned with reduced atmospheric CO₂ levels. Both terrigenous herbaceous vegetation and aquatic lipid content increased significantly. On orbital timescales, correlations between diatom and coccolithophore contents and other climate indices, including Antarctic Circumpolar Current (ACC) strength, atmospheric CO₂, Fe MAR, and global ice volume (δ¹⁸O_B), were predominantly expressed on a 100-kyr cycle, whereas the Ca/Si ratio showed stronger correlations on a 40-kyr cycle. Furthermore, after the MPT, the relationship between surface phytoplankton structure, biological pump efficiency, and atmospheric CO₂ weakened, while the influence of physical process indicators such as ACC strength, global ice volume, and Fe MAR became increasingly pronounced. These results indicate that oceanic physical processes, including ACC strength and bottom-water ventilation, became the primary drivers of CO₂ dynamics after the MPT, diminishing the relative role of biological processes.

As a closed basin at one of the highest points of the East African Rift System, Lake Nakuru shows significant changes in lake level from annual to millennial timescales even during times of minor precipitation change. Various studies have focused on Lake Nakuru in part due to abundant archaeological sites within the surrounding basin. Despite research attention focused on Nakuru's record related to rift-wide environmental reconstructions across the East African Rift System, little focus has been made on its own unique sedimentary record. Here we present a new multi-proxy record from the upper ∼11.5 m of two duplicate 17-m drill cores from Lake Nakuru. Using lithological, diatom, total nitrogen, total carbon, total organic carbon, and micro-x-ray fluorescence data with a multi-annual to decadal time resolution, we provide insights into lake depth and hydroclimatic changes of the past 35,000 years. The available age model indicates recurring anoxic phases based on μ-XRF and lithological data coeval with low diatom species richness and abundant <em>Thalassiosira rudolfi</em> ∼35, ∼25.5 to 24.5, and 19.5 to 17.5 ka. <em>T. rudolfi</em> therefore acts as an indicator of highly productive and/or deeper waters with limited mixing rather than of higher conductivity/pH, strictly due to increased evaporation within the basin. This indicates the challenge of <em>T</em><em>.</em> <em>rudolfi'</em>s use within highly alkaline soda lakes like Lake Nakuru. Other lake phases evident through this record include dry, shallow conditions from 24.5 to 19.5 ka, alkaline conditions from 17.5 to 15.4 ka, and a variable deepening phase from 15.4 to 13.6 ka followed by a more stable deep phase from 13.6 to 12.6 ka. We propose that hydroclimate changes at Lake Nakuru during this time, including presumed wet, anoxic phases, may be related to high and low latitude teleconnections in sea surface temperatures and moisture availability over the Late Pleistocene.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"369 ","pages":"Article 109579"},"PeriodicalIF":3.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144926468","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}

Here, we use carbon and nitrogen contents, Fourier Transform Infrared (FTIR) spectroscopy, and boron isotopes in a sedimentary archive to investigate past fire events in Namadgi National Park (southeastern Australia) and estimate their characteristics such as fire intensity and severity. Strontium and neodymium isotopes were used to assess the possible catchment-scale erosion events following fire. The aromatic/aliphatic ratio of sediments showed that fire frequency and intensity have increased in the last 200 years compared to the previous 3000. Boron isotopes were influenced by both lithology and fire severity, where negative excursions may result from higher contributions of bark to mineral ash, whilst positive excursions in the isotope ratio result from higher contributions of leaves. Negative excursions in the B isotope ratio, coinciding with positive excursions in the aromatic/aliphatic ratio, were hypothesised to record low-severity fires that experienced longer residence times. This multi-proxy approach provides valuable insights into past fire characteristics. By improving our understanding of how fire characteristics have changed in the past, the results can inform mechanistic models to improve predictions of fire severity and intensity changes in the future.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"369 ","pages":"Article 109605"},"PeriodicalIF":3.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144921981","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}

Using both geologic reconstructions of relative sea-level (RSL) change and geodetic determinations of vertical land motion, we assess GIA model accuracy and determine model parametric uncertainty. Seven ice history models and 440 spherically symmetric Earth viscosity models were used to explore the model parameter space. Our results indicate that the inferred earth model parameters are highly dependent on the barystatic component of the adopted ice sheet model. On the other hand, the modelled RSL output is relatively insensitive to variations in the ice thickness distribution of the Eurasian component of the ice history model. Of the two global ice models considered (ANU and ICE-6G) our results demonstrate the barystatic component of the ANU model to be more accurate. Model uncertainty was determined using data-model misfit values and a Bayesian approach to define a subset of parameter sets (1σ confidence). When considering the model uncertainty, 95 % of the Holocene RSL observations and 93 % of the present-day vertical land motion rates can be explained at this confidence level. Our results support previous work in showing that GIA-related subsidence along the Atlantic coast of Europe is dominated by ice-loading (peripheral bulge) effects and that ocean loading is also important in some areas, such as northwestern France. Using our subset of best-fitting parameter sets, we performed a sea-level budget analysis for the period 1957 to 1997 using data from 10 tide gauges in our study region and find that the sterodynamic signal is the largest contributor at most of the considered tide gauge sites, followed by contributions from GIA and glaciers. The GIA signal dominates the modelled uncertainty at all sites. Of the 10 tide gauge stations considered, the budget is closed at six (to within 2σ uncertainty). The largest residual was found for station Dieppe in northern France, with an unexplained signal of 3.8 ± 0.6 mm/yr, which appears to be related to localized subsidence at the tide gauge site.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"369 ","pages":"Article 109577"},"PeriodicalIF":3.3,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144913219","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}

Marine Isotope Stage 5 (MIS 5, ∼130–∼70 ka) – the most recent warm interglacial – serves as a crucial testbed for evaluating potential impacts of future climate change on Central Asian hydroclimate, yet high-resolution precipitation records from this vast region remain exceptionally sparse. Consequently, the mechanisms governing MIS 5 moisture variability across Central Asia (CA), and their broader implications for ecosystem dynamics and early human dispersals, are still poorly resolved. This study reconstructed precipitation variability in Tajikistan, southern CA, during MIS 5, using principal component analysis of multiple paleoclimatic proxies preserved within loess deposits. The results reveal that the precipitation pattern in southern CA differs markedly from those in other parts of Eurasia. We investigated the likely factors influencing the difference using Convergent Cross-Mapping (CCM), and identified a fundamental transition around 102 ka for precipitation dynamics in southern CA, moving from a predominantly westerlies-forced state to a regime limited by moisture availability in source regions. Temperature-driven atmospheric moisture emerged as the primary determinant. Our findings offer valuable insights into near-future climate scenarios in southern CA, such as a likely regional increase in rainfall. Based on the MIS 5 precipitation reconstruction, we argue that the dominance of cold-season precipitation in southern CA may have impeded the northward migration of anatomically modern human (AMH) during MIS 5 north of the Central Asian mountains. We therefore recommend incorporating precipitation seasonality into simulations of AMH dispersal as a factor influencing dispersal routes and timing.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"369 ","pages":"Article 109594"},"PeriodicalIF":3.3,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144913255","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, this kind of investigation is limited due to the access and costliness of this instrumentation.
