Linking terrestrial and marine ecosystem responses to climate variability since the Last Interglacial in southeast European refugia (Lake Ohrid and Gulf of Corinth)

这个ICDP/IODP混合项目旨在：(a)将巴尔干半岛两个保护区（北部的Ohrid/ICDP和南部的Corinth/IODP）在上一个百年尺度的气候周期内的敏感植被响应联系起来，(b)在末次间冰期以来的特定层位上，在局部和区域尺度上研究陆地和海洋生态系统对全球气候变率的响应之间的领先-滞后关系。这两个研究区域位于地中海东部的战略位置，对气候突变非常敏感，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。通过对平杜斯山脉最北端和最南端避难地植被组成、丰度和演替的限制，我们可以重建高振幅气候突变时期的生物气候阈值和植被动态。除了植被的变化，科林斯湾的沉积物也捕捉到了海洋生态系统的变化。因此，陆地和海洋领域之间气候变率的局部表现的领先和滞后可以绕过时间上的不确定性来确定。因此，在亚轨道尺度上了解裂谷系统内气候、环境和构造因素之间的相互作用将使我们能够追求IODP Exp. 381中提出的主要目标。鉴于，通过研究末次冰期温带树木种群的多样性和丰度，本项目解决了SCOPSCO ICDP项目关于东南欧植物恢复力和保护策略的主要科学目标之一。

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.
