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

国际冰川中心/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)在百年尺度上的上一个气候周期的敏感植被反应联系起来；(B)在自上一次间冰期以来的特定地层层中，在地方和区域范围内审查陆地和海洋生态系统对全球气候变化的反应之间的领先和滞后关系。这两个研究区的战略位置位于地中海东部，那里对突然的气候变化高度敏感，从而能够探测到高纬度(例如北大西洋)和低纬度(非洲季风)的影响。限制平地斯山脉北部和最南部避难所的植被组成、丰度和演替，将使我们能够在气候突然高幅度振荡期间重建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，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异性的当地表达的领先和滞后。因此，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.然而，通过研究末次冰期温带树木种群的多样性和丰富性，该项目解决了南欧合作组织ICDP项目的主要科学目标之一，该项目涉及东南欧的植物复原力和保护战略。

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.
