However, current vegetation reconstructions since the Last Glacial Maximum (LGM) have not yet provided a complete and continuous presentation of global-scale vegetation evolution. In this study, we systematically compiled 3286 pollen records and applied the biomization method to reconstruct global vegetation patterns on a millennium resolution since the LGM. Our results show that during the LGM, the mid- and high-latitudes of the Northern Hemisphere were primarily covered by tundra, with steppe and open coniferous forests in western North America, taiga in eastern North America, and steppe dominating much of Eurasia. In the low latitudes, tropical rainforests retreated significantly compared to the present, while arid shrubland expanded across much of Africa. Since the deglaciation, forests have gradually expanded, with cold-adapted biomes shifting to higher latitudes. In the mid-latitudes, mixed forests and deciduous broadleaf forests increased in North America, Europe, and China. During the early to mid-Holocene, forests dominated in the mid- and low-latitudes, while tundra and taiga dominated in the high-latitudes. By the late Holocene, steppe and desert expanded in central North America and northern China, while tropical rainforests flourished in South America. The results further reveal that the global forest cover increased by ∼31 % from the LGM to the mid-Holocene, then decreased by ∼5 % at the late Holocene. In the mid-to high-latitudes of the Northern Hemisphere, forest cover varied significantly, rising notably from the LGM to the early and mid-Holocene, peaking around ∼7–5 ka BP, and declining after ∼5 ka BP. Conversely, the mid-latitudes of the Southern Hemisphere exhibited a more gradual pattern, with forest percentage peaking earlier ∼12–8 ka BP, and maintaining relatively stable afterward. Tropical regions had more erratic changes, initially fluctuating between 18 and 15 ka BP, followed by steady growth peaking ∼4–6 ka BP, and continued fluctuations thereafter. Our results reveal asynchronous vegetation changes across different global regions and provide a biome-level perspective, offering a finer classification of vegetation dynamics compared to previous global-scale studies. This dataset has the potential for comparison with palaeovegetation simulations, promoting better integration with different vegetation classification schemes. Moving forward, increasing the data density and integrating simulations will be crucial for a deeper exploration of the feedback mechanisms between vegetation evolution and climate change, thereby enhancing the accuracy of predictions of future vegetation dynamics.</div></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":"729 ","pages":"Article 109780"},"PeriodicalIF":1.9,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143807650","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}

Various chemical pretreatments have been developed to remove organic and inorganic contaminants and to clean the head capsules prior to isotope analysis, but so far there is no standardised routine method to assess the purity of the isolated chitin. We present a dataset of oxygen isotope analyses of head capsules from seven lakes in southern South America. The head capsules were assigned to three different taxonomic groups of Chironomidae (Chironominae, Orthocladiinae, Tanypodinae) and to Ceratopogonidae. Orthocladiinae exhibited on average higher isotopic fractionation relative to lake water than the other taxonomic groups, although these differences were not statistically significant. Elemental analyses demonstrate that the oxygen content and molar N/O ratio of the head capsules have a larger influence on oxygen isotopic composition than the host water isotopic composition suggesting a strong influence of incomplete deproteination on oxygen isotope values of chironomid head capsules. This is backed up by an experimental approach with differently pretreated chironomids, which exhibits a strong correlation with N/O ratio presumably due to various degrees of deproteination. According to the N/O ratio, pure chitin was obtained after removal of the minerogenic fraction with a mixture of 10 % HF and 5 % HCl (16 h, 20 °C) and subsequent treatment with 5 % NaOH (2 h) and 7 % NaClO<sub>2</sub> (10 h).

This is possible thanks to the large amount of wood samples, both charred and waterlogged, which belong to building structures as well as furniture. Our work consisted both in a review of published data and in the identification of 62 new waterlogged wood remains. The literature permitted to collect information on various types of building elements and wooden furniture. In total, 641 samples (charcoal and waterlogged wood) were counted. Softwood is by far the preferred timber for both building purposes and furniture. <em>Abies alba</em> Mill. is especially used, this fact suggesting a more important role played by this species in southern Italian forests during the recent Holocene; its decline is probably due to the overexploitation characteristic of the Roman period. The significant presence of <em>Cupressus sempervirens</em> L., mainly used for poles production, confirms that this tree was cultivated in plantations for timber production in the Vesuvius area. The presence of <em>Picea abies</em> (L.) H. Karst indicates the importation of timber from the Alps.
