1Vegetation and Climate Reconstruction of the Planalto in Rio Grande do Sul, South Brazil (Late Glacial and Holocene)显示文摘A 405 cm long core was drilled in the Aparados da Serra National Park (Rio Grande do Sul, Brazil) at the end of 1999, and in all, 23 samples were taken for palynological investigation. The cores’ age is estimated at 27 000 a BP based on three radiocarbon dates taken from different depths of the core. Palynological methods were used to reconstruct the history of vegetation and climate change. Four different plant associations were recognized: ① lake plankton and shore plants; ② mire and swamp plants; ③ gallery-forest plants; ④ campos vegetation. Climate changed from cold glacial conditions mainly influenced by the South Pole throughout several transition stages to today’s humid warm climate, mainly being influenced by the Brazil stream.M.Herrmann A.R.Ashraf V.Mosbrugger M.M.Toigo 2003Global Geology2003,8,2:0
