In July and September 2002, δ13C and Δ18O wereKeywords: carbon; oxygen; water; carbon isotope; climate change; deciduous tree; isotopic composition; organic matter; oxygen isotope; phloem; water exchange; article; beech; biological model; climate; Europe; fractionation; geography; metabolism; photosynthesis; p Steady-state evaporative enrichment; Stomatal conductance; Xylem sap, water balanceCarbon isotopic composition and oxygen isotopic enrichment in phloem and total leaf organic matter of European beech (Fagus sylvatica L.) along a climate gradient200610.1111/j.1365-3040.2006.01520.x2015-12-08
