Transformation of regional vegetation driven by climate change during the last deglacial-early Holocene at Chaohu Lake, eastern China: New pollen insights
Reconstructing the vegetation history of east China during the last glacial-interglacial transition is crucial for understanding the East Asian Summer Monsoon (EASM) evolution. Here, we present a new high-resolution pollen record from Chaohu Lake to determine the detailed process of regional lowland...
