This study presents a modern palynological dataset from subsurface sediments of the shallow Burano and Orbetello lagoons in Tuscany, Italy. This dataset is part of a broader project which includes fossil sediment cores from the same basins. Spatially distributed samples were analyzed for grain-size, pollen, non-pollen palynomorphs, and sieved charcoal, with water physico-chemical parameters measured at each site. Terrestrial pollen assemblages mainly reflect regional wind-pollinated vegetation but show strong distortions, with forests overrepresented and open areas—especially cereal crops and vineyards—underrepresented. Modern calibration of <em>Pinus</em> and <em>Olea</em> pollen registrations is particularly informative given their key role in local human-driven landscape change. Sieved charcoal (&gt;<!--> <!-->125 μm), a proxy for local fire, is unevenly distributed and correlated with <em>Glomus</em> chlamydospores, indicating additional transport via runoff. At Burano, intra-basin pollen deposition is largely controlled by morphometric and sedimentological factors which explain 58.1% of the observed variance. In contrast, at the Orbetello lagoon, these factors explain only 26.7% of the variance, reflecting more complex hydrodynamic controls on sediment and pollen redistribution. Among aquatic groups, brackish macrophytes dominate across broad salinity ranges, primarily controlled by water depth, salinity, and associated with dissolved oxygen. Microalgal groups respond to temperature and nutrient availability, with high concentrations of harmful algae (<em>Alexandrium</em> spp.) indicating ecological stress. Overall, this modern spatial dataset provides a site-specific framework for interpreting fossil records and reconstructing past environmental changes. It also demonstrates the potential of combining palaeoecological research with modern data to translate scientific knowledge into practical applications for biodiversity conservation.</div></div>","PeriodicalId":54488,"journal":{"name":"Review of Palaeobotany and Palynology","volume":"347 ","pages":"Article 105502"},"PeriodicalIF":1.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146023912","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}

Phytogeographical evidence further revealed that <em>Nyssa</em> species (including <em>N. sibirica</em>) originated in warm and humid environments millions of years ago. However, due to their limited adaptability to global climate cooling, their distribution ranges gradually contracted southward during the Neogene. Additionally, simulations using the BioClim model showed that even under a scenario where global temperatures rise by no more than 1.5 °C compared to pre-industrial levels, the distribution ranges of extant <em>Nyssa</em> species have not expanded but have instead generally undergone significant reduction, with some species (such as <em>N. sinensis</em> and <em>N</em>. <em>talamancana</em>) even facing the risk of extinction.

Ammonites <em>Blaschkeiceras</em> sp. and <em>Ernstbrunnia</em> sp. are identified underlying the newly reported palynological association belonging to the Standard Tethyan <em>Fallauxi</em> Zone.

The presence of ammonites and the dominance of marine palynomorphs indicates a marine or paralic depositional environment, likely within the neritic zone. The marine fraction of the palynological association is dominated by Gonyaulacales and indicates an environment with low nutrient availability. The plant communities, likely located in coastal areas close to the depositional site, were dominated by Cheirolepidiaceae conifers suggesting warm conditions.

Notably, a distinct cell wall gap is present between adjacent polygonal cells within a row, facilitating intercellular connectivity and suggesting that these rows functioned as a cohesive structural unit. This configuration supports a revised symmetry model for the utricle, expressed as (2-1-3-1-2) × 2, where the numbers denote groups of cell rows interconnected via wall gaps. The Armenian material further shows that the presumed oospore was directly enclosed within the utricle, lacking a gyrogonite. Small canals in the poles of polygonal cells may have enabled limited exchange between the egg cell and the external environment through the thick utricle wall. The prominent central canal is interpreted as the last repository of the cytoplasm during the final stages of a centripetal calcification.
