Stable isotope ratios in tree-ring cellulose have bee shown to be reliable recorders of changes in the ambient climate (Leuenberger et al., 1998). thus, isotopic fractionations associated with both physical and biochemical processes during cellulose synthesis in higher plants (Epstein & Krishnaumurthy, 1990; Roden et al., 2000; Saucer et al., 1997a; 1997b; 2000) can be used as archives for past climatic indicators. Superimposed on the climatic inducedisotopic signal are the long-term responses of plant physiological processes to past changes in environmental conditions including CO_2 enrichment.
