"Hereinafter, we focus only on the results for n-C26 as these consistently had the highest, most evenly-shaped peaks and the peaks were present in the most samples."- Terwilliger et al., 2013; ISO2k name: SL13TEAK

dDn-C26 data unambiguously if perhaps qualitatively reflect changes in precipitation despite potentially confounding influences of vegetation type and other factors. "The dD values of the fatty acids from land-plant sources (n-C26, n-C28, n-C30) were significantly correlated to one another in each site"

precipitation occurs in closest proximity to the bulk of global cloud formation and its dD values are most influenced by its amount. dD values de- crease as precipitation amount increases (Risi et al., 2008). Additional factors shape the dD values of fatty acids in land-plants as well but their consideration below suggests that our dDn-C26 sequences were unambiguously if qualita- tively reflecting changes in amount of precipitation.

Plant to plant differences in fractionations between dD values of n-alkyl compounds and their precipitation source may introduce the greatest error in interpreting rainfall amount.
