摘要: The Velay sequence (France) provides a unique, continuous, palynological record spanning the last four climatic cycles. A pollen-based reconstruction of temperature and precipitation displays marked An analysis climate vegetation changes during interglacial periods reveals comparable features identical major successions. Although Marine Isotope Stage (MIS) 11.3 Holocene had similar earth precessional variations, their correspondence in terms dynamics is low. MIS 9.5, 7.5, especially 5.5 display closer correlation to than 11.3. Ecological factors, such as distribution composition glacial refugia or postglacial migration patterns, may explain these discrepancies. Comparison ecosystem past five interglacials suggests that development current has no analogue from 500,000 years.
