"Thermo Trace2000 GC equipped with an SGE SolGel-1ms column (60 m  0.25 mm  0.25 lm) and a PTV injector coupled to a Finnigan MAT 253 stable isotope mass spectrometer and a Finnigan GC combustion III interface. The H3+ factor was measured daily prior to dD analysis, with a mean value for the measurement peri- ods of 15.6 ± 0.3 (1r). An external FAME isotope standard (Mix F8, Indiana University Biogeochemical Laboratories) and an internal laboratory isotope standard, measured after every four to six sample analyses, were used to standardize and normalize sample isotope values. The precision of the standard analyses was 6±5& for dD analyses and 6±0.5& for d13C analyses. Most samples were run in duplicate or triplicate for both hydrogen and carbon isotope analysis, and the reported isotope ratio values are averages of replicate runs. Insufficient abundances for some long-chain FAME samples prevented replicate dD analyses."

Past variability in ?Dwax-corr reflects the combined effects of evaporative enrichment of soil and plant water D/H ratios and temporal variability in the isotopic composition of pre- cipitation, which, in this region, is primarily controlled by the amount effect (8, 27)...Therefore we interpret ?Dwax-corr values as a qualitative indicator of past water availability.
