英文摘要:

The nature and duration of the Last Glacial Maximum (LGM) in Australia are poorly understood, with little regional agreement on the timing and direction of LGM climate changes. One reason for this is that Australian Late Pleistocene terrestrial sediments typically are both sparse and inorganic, inhibiting the development of detailed radiocarbon chronologies. To address this problem, we extracted fossil pollen from radiometrically dated stalagmites collected in southwest Western Australia. Our pollen record, supported by 30 U-Th dates, reveals the vegetation response to Late Pleistocene climates between similar to 34 and 14 ka, through the body of the LGM. Before similar to 28 ka, sclerophyll forests were more open than today, but at similar to 28 ka forest cover was essentially eliminated, and treeless conditions were maintained until progressive reforestation at similar to 17.5 ka. This similar to 10-ka-long full glacial episode correlates with other mid-high latitude Southern Hemisphere records, suggesting that LGM environmental changes were closely coordinated across the hemisphere.
