It is thus essential to elucidate the effects of climate change and human disturbances on the dynamics of different forests. Here we selected the forest of Yunnan pine (YNP) (<em>Pinus yunnanensis</em>), an endemic tree species in Southwest China as an instance, to examine its dynamics since the Last Glacial Maximum (LGM) in central Yunnan where it predominantly occurs, using fossil <em>Pinus</em> pollen percentages and its estimated plant abundances in four lake catchments, central Yunnan. Our study reveals that the dynamics of YNP forests (YNPFs) were principally associated with climatic conditions at 20,000–2500 cal. a BP, whereas the dynamics of YNPFs after 2500 cal. a BP were significantly affected by human activities such as agriculture as well as the extraction and processing of mineral resources in central Yunnan. A long-term and big deforestation occurred at 2500–800 cal. a BP, which was caused by human activities. The restoration of YNPFs in central Yunnan after 800 cal. a BP was predominantly attributed to the natural succession of the secondary vegetation, and reforestation with the aid of ecological protection policies at the end of the 20th century has made its contribution to the recovery of YNPFs in recent decades. Climatic conditions driven by monsoon intensity and seasonal insolation as well as human activities are major factors controlling the dynamics of YNPFs in central Yunnan. Especially, the impact of human activities on YNPFs became more pronounced over the past 2500 years. Our findings not only provide a reference for understanding the interrelationships among forests, ecological environments, climate change, and human activities in central Yunnan, but also offer scientific data for making sustainable forest management policies and ecological conservation strategies.</div></div>","PeriodicalId":54488,"journal":{"name":"Review of Palaeobotany and Palynology","volume":"336 ","pages":"Article 105311"},"PeriodicalIF":1.7,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143551672","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}

In the past, this taxon was distributed across much of the Neotropics, reaching its maximum extent during the Oligo-Miocene. The occurrence of <em>Pelliciera</em> outside the Neotropics had been debated based on a few fossil pollen records from Africa and Europe, though many of these records have been questioned. However, the recent proliferation of fossil pollen records identified as the fossil representatives of <em>Pelliciera</em> pollen warrants reconsideration. This paper provides a detailed review of the morphological features of extra-Neotropical records published to date, comparing them with extant <em>Pelliciera</em> pollen. Over 80 records from Africa, Europe, the Middle East, and North America were retrieved for this review. Only those published in Scopus-indexed journals are considered to avoid issues related to gray literature and predatory journals. Records mentioning purported <em>Pelliciera</em> fossils without providing material suitable for morphological comparison were also excluded, as were those featuring poor-quality images impossible to resolve. Among the records that met these criteria, only a subset of African fossil pollen types are compatible with <em>Pelliciera</em>: three with high reliability and another three with medium-high reliability, ranging from the Eocene to the Plio-Pleistocene. With these data, the occurrence of <em>Pelliciera</em> fossil pollen outside the Neotropics cannot be dismissed. However, the evidence remains insufficient to construct a transcontinental biogeographical and evolutionary framework for <em>Pelliciera</em> over time.

These oceanographic and environmental instabilities influenced climate evolution and the associated vegetation communities in adjacent continental regions. During this period, the Tethys Ocean flooded much of North Africa, resulting in the deposition of thick carbonate and siliciclastic sequences. In this study, a detailed palynomorph and palynofacies investigation of twenty-eight cuttings and core samples from the Bahariya Formation in well Salam-17 of the Shushan Basin, north Western Desert (Egypt) was conducted to reconstruct the vegetation ecosystem and its response to climatic and depositional environmental changes during the early-middle Cenomanian. Statistical analysis revealed two distinct clusters of particulate organic matter (POM) components, corresponding to two palynofacies assemblages (PFA-1 and PFA-2). PFA-1, which occurred in most of the samples, is characterized by high proportions of phytoclasts, suggesting deposition in fluvio-deltaic to marginal marine environments. PFA-2 is dominated by high abundances of AOM, revealing a shallow inner shelf environment with limited terrestrial input. A rich assemblage of humidity palynomorph indicators, including fern spores, conifer pollen from Taxodiaceae and Araucariaceae, points to predominantly warm and humid climates during the early-middle Cenomanian. However, the abundant presence of aridity palynomorph indicators, such as gnetalean Elaterates and Ephedroids, along with coniferous Cheirolepidiaceae, in the upper part of the Bahariya Formation indicates a short-lived phase of semi-arid to arid conditions during the late early Cenomanian. The high abundances of megathermic plant communities suggest that a warm climate prevailed throughout the succession. Regional correlations indicate that the warm arid to semi-arid phase is coeval throughout the north Western Desert, corresponding to the early Cenomanian <em>Elaterosporites klaszii</em> Interval Zone.</div></div>","PeriodicalId":54488,"journal":{"name":"Review of Palaeobotany and Palynology","volume":"335 ","pages":"Article 105297"},"PeriodicalIF":1.7,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143238735","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}
