However, the relationship between charcoal morphotypes and plant types has never been formally tested in tropical environments, despite its potential to improve understanding of fire regimes and deforestation, and to analyze long-term ecosystem resilience. Separation between herbaceous and woody charcoal commonly relies on a fixed elongation threshold, but this arbitrary division overlooks the morphological continuum of charcoal and may bias interpretations. To address this, we developed a Bayesian model to classify charcoal fragments into herbaceous and woody subpopulations based on their elongation distributions. We applied it to 19 sediment charcoal records spanning the last 30 years across a broad geographic and vegetation gradient in West and Central Africa. Compared with contemporary vegetation cover derived from remote sensing, the estimated proportion of woody charcoal was significantly positively correlated with tree cover, validating our approach and confirming charcoal elongation as a reliable proxy for past fire-related biomass sources. Finally, we applied the model to a paleosequence from Lake Sélé (Benin) to reconstruct temporal changes in biomass and compared results with fossil pollen data, further assessing the proxy relevance for reconstructing past fire regimes and advancing tropical paleoecology.","PeriodicalId":16929,"journal":{"name":"Journal of Quaternary Science","volume":"41 3","pages":"490-506"},"PeriodicalIF":2.2,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jqs.70053","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147686239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These SLIPs constrained Holocene RSL changes in the region between ~8300 cal BP and ~6018 cal BP and captured the Main Postglacial Transgression. These ten new points are combined with the ten pre-existing SLIPS from the southern Solway Firth to greatly refine the trend of Holocene RSL changes across this region. The Main Postglacial Transgression was shown to occur between ~8320 and 7500 cal BP, reaching a highstand of 3.26 ± 0.56 mOD. The new data were combined with 73 existing SLIPS from two sites around the northern Solway Firth and compared to RSL predictions from glacial isostatic modelling. Comparison between the corrected SLIPs and RSL predictions using British and Irish ice sheet reconstructions showed that the timing of the Main Postglacial Transgression is best captured with a hybrid model for the presence of thick and thin ice sheets. Pollen analysis at Cowgate Farm and Herd Hill provided a record of vegetation and coastal changes, acting as a chronostratigraphic marker when compared to published pollen records of the region.

The new tephra has two glass populations and is matched to the ~322 ka Matahina caldera-forming eruption. High-resolution sampling of peat bracketing the KOT and Rangitawa Tephra reveals marked changes in local vegetation following the deposition of both tephras.

We reconstruct here for the first time this transition in a region of Anatolia located close to Constantinople through pollen analysis of a sediment core from Lake Yeniçağa, dated to between ~2300 and ~1200 cal a BP.

Crucially, this model of land exploitation was also constrained by the climatic oscillations that reflected its transitional location between the Aegean, Central Anatolian, and Black Sea climate regions.

The oldest faunas, dated to the Muchkap (MIS 15) and Likhvin (MIS 11) interglacials, belonged to the Late Tiraspolian and Gun'ki small mammal complexes, respectively. Later faunas, corresponding to the Kamenka, Romny, and Mezin paleosols, included chronotaxa morphologically close to modern species. The youngest Middle Pleistocene fauna most likely correlates with the Romny interglacial (MIS 7). The youngest overall fauna dates to the Bryansk (=Denekamp) interstadial (late MIS 3). We performed the first comprehensive analysis of the quantitative composition of these faunas using multivariate analysis and inferred qualitative relationships among them. The main component of variation in faunal composition identified by non-metric multidimensional scaling (first NMDS axis) reflects evolutionary changes in the phyletic lineages of steppe lemmings (Lagurus) and narrow-headed voles (Stenocranius). The other two components correlated with the geographical position (longitude and latitude, respectively) of the sections, most likely reflecting a relatively stable pattern of variation in ecological conditions across the East European Plain. The faunal composition suggests that the animals inhabited semi-arid and arid steppe habitats, and that the paleosols formed during the warmest and driest phases of the interglacials in Eastern Europe. The non-analog Bryansk interstadial complex is associated with conditions of periglacial, mosaic steppe–tundra-like environments.
