This hybrid ICDP/IODP project aims to: (a) link the sensitive vegetation response from two refugial sites across the Balkan peninsula (Ohrid/ICDP in the north and Corinth/IODP in the south) over the last climatic cycle at a centennial scale, (b) examine lead-lag relationships between terrestrial and marine ecosystem response to global climate variability at a local and regional scale in specific stratigraphical horizons since the Last Interglacial. The two study areas are strategically positioned in the Eastern Mediterranean that is highly sensitive to abrupt climate variability allowing to detect influences from both higher (e.g North Atlantic) and lower latitudes (African monsoon). Constraining the vegetational composition, abundance and succession in the northern- and southernmost refugial sites across the Pindus mountain range will enable us to reconstruct bioclimatic thresholds and vegetation dynamics during a period of abrupt high-amplitude climate oscillations. Besides vegetation shifts, sediments from the Gulf of Corinth also capture changes in marine ecosystems. Hence, leads and lags in the local expression of climate variability between the terrestrial and marine realms can be determined bypassing chronological uncertainties. Understanding the interplay between climatic, environmental and tectonic factors at sub-orbital scale within the rift system will thus allow us to pursue the major objective laid out in the IODP Exp. 381. Whereas, by examining the diversity and abundance of temperate tree populations during the Last Glacial, this project tackles one of the principal scientific goals of the SCOPSCO ICDP project dealing with plant resilience and conservation strategies in southeastern Europe.

该 ICDP/IODP 混合项目旨在：(a) 将巴尔干半岛两个避难地（北部的奥赫里德/ICDP 和南部的科林斯/IODP）在百年尺度上一个气候周期中的敏感植被响应联系起来， (b) 研究自末次间冰期以来，在特定地层范围内，陆地和海洋生态系统对全球气候变化的响应之间的超前-滞后关系。这两个研究区域战略性地位于东地中海，该地区对突然的气候变化高度敏感，可以检测来自高纬度（例如北大西洋）和低纬度（非洲季风）的影响。限制品都斯山脉最北端和最南端避难地的植被组成、丰度和演替，将使我们能够在突然的高振幅气候振荡时期重建生物气候阈值和植被动态。除了植被变化之外，科林斯湾的沉积物还记录了海洋生态系统的变化。因此，可以绕过时间上的不确定性来确定陆地和海洋领域之间气候变化的局部表达的超前和滞后。了解裂谷系统内亚轨道尺度的气候、环境和构造因素之间的相互作用将使我们能够实现 IODP Exp. 中提出的主要目标。 381. 鉴于，通过检查末次冰期期间温带树木种群的多样性和丰富度，该项目实现了 SCOPSCO ICDP 项目的主要科学目标之一，该项目涉及东南欧的植物恢复力和保护战略。
