Prof. Blas L. Valero-Garcés，西班牙比利牛斯生态研究所所长，主要从事湖泊沉积重建的过去全球变化（气候、环境和人类活动影响）研究。研究方法涉及沉积学和地球化学指标以及综合的生物指标。主要研究地区涉及南美（智利、阿根廷、的的卡卡湖）、北美（盐湖和北美大平原）、西班牙和复活节岛，主持过多个国际和西班牙国内研究项目，发表研究论文100余篇，其中SCI收录论文超过60篇。

本期讲座主要内容：Iberian karstic lakes are particularly sensitive to moisture changes due to their relative small size and their hydrologically-closed basins. Detailed sedimentological and geochemical analyses complemented with some biological proxies (chironomids, diatoms, pollen) have been performed in those cores, in the frame of a multidisciplinary strategy. Climate and environmental evolution have been reconstructed from several Iberian lake records to investigate whether common signals of the Iberian- Roman Humid Period, the Cold Dark Medieval Ages, the Medieval Climate Anomaly and the Little Ice Age are detected and what are the most plausible climate mechanisms.
