|a A reconstruction of past environmental change from Ecuador reveals the response of lower
montane forest on the Andean flank in western Amazonia to glacial-interglacial global climate
change. Radiometric dating of volcanic ash indicates that deposition occurred ~324,000 to
193,000 years ago during parts of Marine Isotope Stages 9, 7, and 6. Fossil pollen and wood
preserved within organic sediments suggest that the composition of the forest altered radically in
response to glacial-interglacial climate change. The presence of Podocarpus macrofossils ~1000 meters
below the lower limit of their modern distribution indicates a relative cooling of at least 5°C during
glacials and persistence of wet conditions. Interglacial deposits contain thermophilic palms
suggesting warm and wet climates. Hence, global temperature change can radically alter
vegetation communities and biodiversity in this region. |
