Long-term environmental changes in a tropical
rainforest
Comparison of a) insolation at 20S during
austral summer (Feb) (Berger and Lourtre, 1991)
and b) Antarctic temperature (EPICA, 2004) with
reconstructed forest cover (c) and rainforest
floral biodiversity (d Shannon-Weaver (SW)
Index) obtained from pollen analysis of Core CO3
located in the Atlantic rainforest at Colônia São
Paulo, Brazil (2352S 464220W 900 m asl).
Ages shown in grey are extrapolated and should be
interpreted with caution (Figure modified from
Ledru et al., 2009).
