本研究提出了一个水文气候重建Crvena斯蒂耶纳（黑山，巴尔干半岛的半岛），岩石庇护所，已产生的证据，旧石器时代中期人类占领。在7米深的垂直沉积序列中，脂质生物标志物，氢（δD）同位素组成的正构烷烃，和有机元素地球化学的整合，使重建的主要水文和环境变化期间的MIS 3和它们的相关性在现场。我们应用凝聚层次聚类和主成分分析的地球化学，分子和稳定同位素数据，以获得一个强大的水文记录。我们发现证据的三个干旱趋势的研究期间，其中之一与海因里希事件5，潮湿和冷温带条件下，考古丰富的层。我们的数据集还有助于了解过去的水文变化在巴尔干半岛的半岛，一个敏感的地区，短暂的气候变化，并在整个地中海地区在最后一次冰期/间冰期循环。
This study presents a hydroclimatic reconstruction from Crvena Stijena (Montenegro, Balkan Peninsula), a rock shelter that has yielded evidence for Middle Paleolithic human occupation. The integration of lipid biomarkers, hydrogen (δD) isotopic compositions ofn-alkanes, and organic elemental geochemistry in the 7-m deep vertical sedimentary sequence enables reconstruction of the main hydrological and environmental changes during the MIS 3 and their correlation with the presence at the site. We apply agglomerative hierarchical clustering and principal component analysis to the geochemical, molecular, and stable isotopic data to obtain a robust hydrological record. We find evidence of three aridity trends from the studied period, one of them correlated with the Heinrich Event 5, and humid and cold-temperate conditions in archaeology-rich layers. Our dataset also contributes to the knowledge of past hydrological variability in the Balkan Peninsula, a sensitive area to short-lived climatic shifts, and overall, in the Mediterranean region during the last glacial/interglacial cycle.
