The Gebel al-Akhdar is an unique upland habitat island, isolated between the Mediterranean Sea and the Sahara Desert, characterised by a high degree of endemicity amongst its flora and invertebrate fauna, and with an extremely long history of human activity. Orographically-driven rainfall supports dry Mediterranean woodland and maquis on the northern slopes of the Gebel, with scrub-steppe passing into steppe and then pre-desert on the dryer southern slopes. Here we document rainfall/vegetational/pollen relationships along North–South transects across the Gebel al-Akhdar. Vegetation around pollen sample sites was recorded. Precipitation was interpolated from ERA5 satellite data, and from the local meteorological network. Surface pollen assemblages allow us to distinguish habitats with higher effective moisture on the northern slopes of the Gebel from those with lower effective moisture on the southern slopes. Coastal garrigue is characterised by high <em>Pinus</em> pollen, reflecting the very low pollen productivity of this habitat. Despite complexities in the relationship between vegetation and surface pollen, most parts of the rainfall distribution in the Gebel al-Akhdar can be characterised palynologically, giving confidence in the use of palynology to characterise past rainfall regimes in the region.</div></div>","PeriodicalId":54488,"journal":{"name":"Review of Palaeobotany and Palynology","volume":"334 ","pages":"Article 105272"},"PeriodicalIF":1.7,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143157806","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}

In this study, we carry on palynological analysis for an acid sulfate paleosol from Voronezh, Russia. Abundant and well-preserved spores are recognized from the middle part of this paleosol and its overlying shale. The <em>Ancyrospora tichonovitschi</em>–<em>Retispora archaeolepidophyta</em>–<em>Rhabdosporites langii</em> (TAL) assemblage from the paleosol, including spores of 45 genera and 101 species, indicates a late Eifelian?–early Givetian age. This new age constraint on the paleosol is entrenched by another spore assemblage from the lowermost part of the overlying shale, namely <em>Cristatisporites conannulatus</em>–<em>Geminospora decora</em>–<em>Membrabaculisporis comans</em> (CDC) assemblage. This assemblage includes spores of 38 genera and 89 species, and can be well correlated with the early Givetian <em>Cymbosporites magnificus</em>–<em>Hymenozonotriletes tichonovitschi</em> (MT) Subzone in eastern Europe. Both the assemblages are characteristic for the humid subtropical flora. Assessments of sporopollenin degradation within the paleosol lead to the suggestion that low pH value probably plays a significant role in spore preservation and can explain the surprising diversity and abundance of spores.
