Abstract. Sedimentary charcoal records are widely used to reconstruct regional changes in fire regimes through time the geological past. Existing global compilations not geographically comprehensive and do provide consistent metadata for all sites. Furthermore, age models provided these harmonised many based on older calibrations of radiocarbon ages. These issues limit use existing research into past regimes. Here, we present an expanded database records, accompanied by new recalibration...
Abstract. There has been considerable debate about the degree to which climate driven societal changes in eastern Mediterranean region, partly through reliance on a limited number of qualitative records and reflecting need disentangle joint impact different aspects climate. Here, we use tolerance-weighted, weighted-averaging partial least squares derive reconstructions mean temperature coldest month (MTCO), warmest (MTWA), growing days above threshold 0 ∘C (GDD0), plant-available moisture,...
Biomisation has been the most widely used technique to reconstruct past regional vegetation patterns because it does not require an extensive modern pollen dataset. However, well-known limitations including its dependence on expert judgement for assignment of taxa plant functional types (PFTs) and PFTs biomes. Here we present a new method that combines strengths biomisation with those alternative dissimilarity-based techniques.
Abstract Aim We reconstruct vegetation changes since 12 ky in the Eastern Mediterranean to examine four features of regional history that are controversial: extent non‐analogue assemblages transition from Late Glacial early Holocene, synchroneity postglacial forest expansion, geographical temperate deciduous during mid‐Holocene and timing trigger for re‐establishment drought‐tolerant late Holocene. Location The Mediterranean–Black Sea Caspian Corridor. Taxon Vascular plants. Methods 122...
Wildfires have major impacts on terrestrial ecosystems, the global carbon cycle, atmospheric chemistry and climate. Charcoal records from sedimentary sequences provide a way to reconstruct palaeofire regimes at different temporal spatial scales are key resource improve our understanding of drivers wildfires. The RPD version 1 is an updated expanded database charcoal records, accompanied by new Bayesian age models. first contains 1681 1477 sites worldwide. New models been run for 714 records.

Supplementary Table 1. Allocation of pollen taxa found in samples the Eastern Mediterranean-Black Sea Caspian Corridor (EMBSeCBIO) database into 247 types represented SPECIAL Modern Pollen Data Set (SMPDS) (Harrison, 2019).The table indicates taxonomic level aggregation, name used for amalgamated taxon, and component species or genera included this taxon.
<p>The Eastern Mediterranean-Black Sea Caspian Corridor (EMBSeCBIO) region (33°–49°N, 20°–60°E ), is characterized by strong temperature and precipitation gradients topographic heterogeneity, resulting in the clear patterns biome distribution within a relatively limited geographic space. The complexity of this area challenge for reconstructing dynamics vegetation throughout Holocene. In study, we...
<p>The circum-Mediterranean region is characterized by high climatic diversity derived from its orographic heterogeneity and the influence of global marine atmospheric circulation patterns. The also has a long dynamic history human occupation dating back to ~ 8000 years BP.  complexity this area challenge for reconstructing dynamics vegetation through Holocene. Rule-based approaches changing patterns time are insufficient as they require imposition subjective...
