Journal ArticleDOI
A mechanistic model for interpretation of hydrogen and oxygen isotope ratios in tree-ring cellulose
TL;DR: In this paper, a mechanistic model is presented to quantify both the physical and biochemical fractionation events associated with hydrogen and oxygen isotope ratios in tree-ring cellulose, incorporating both humidity and source water environmental information.

The use of isotope tracers for identifying populations of migratory birds
C. P. Chamberlain,Joel D. Blum,Richard T. Holmes,Xiahong Feng,Thomas W. Sherry,Gary R. Graves +5 more
TL;DR: Preliminary analyses of the δD and δ13C composition of feathers collected from warblers in their Caribbean winter grounds indicate that these individuals were mostly from northern breeding populations, and variances in isotope ratios in samples from local areas in winter tended to be larger than those in summer, suggesting that individuals from different breeding localities may mix in winter habitats.
Journal ArticleDOI
Oxygen and Hydrogen Isotopic Ratios in Plant Cellulose
TL;DR: The variations of the D/H and (18)O/(16)O ratios of nonexchangeable hydrogen and oxygen in plant cellulose reveal systematic differences between terrestrial plant groups.

Assessing Ecosystem-Level Water Relations Through Stable Isotope Ratio Analyses
TL;DR: Ehleringer et al. as mentioned in this paper used stable isotope ratio analyses to constrain the analysis of flux data, such as identifying those specific soil layers that are the source of current moisture use by the vegetation or the ratio of carbon dioxide to water (CO2-to-H2O) flux.
Journal ArticleDOI
A reexamination of cellulose carbon-bound hydrogen δD measurements and some factors affecting plant-water D/H relationships☆
Crayton J. Yapp,Samuel Epstein +1 more
TL;DR: In this article, a modified version of the renitration method was used for the analysis of cellulose carbon-bound hydrogen and the results confirmed the conclusion of Epstein et al. that the δD variations of the source water are the dominant control of the cellulose C-H hydrogen from naturally grown plants.

Stable isotopes in precipitation
TL;DR: In this paper, the isotopic fractionation of water in simple condensation-evaporation processes is considered quantitatively on the basis of the fractionation factors given in section 1.2.
Journal ArticleDOI
The concentration and isotopic abundances of atmospheric carbon dioxide in rural areas
TL;DR: In this article, the isotopic abundances of C13 and O18 were analyzed for carbon dioxide reporting, in addition to concentration in air, in order to explain the correlation observed for all samples between C13 isotope abundance and concentration of carbon dioxide in air.
Journal ArticleDOI
The concentration and isotopic abundances of carbon dioxide in rural and marine air
TL;DR: In this paper, the authors reported the analysis of 106 additional samples of rural air and thirteen samples of air collected over tropical waters of the eastern Pacific Ocean and found a correlation between C13 abundance and concentration of carbon dioxide previously observed for forest air.
Journal ArticleDOI
The determination of the D/H ratio of non-exchangeable hydrogen in cellulose extracted from aquatic and land plants
TL;DR: In this article, a method has been developed for the analysis of D/H ratios of non-exchangeable hydrogen in plant cellulose and the overall relationship is linear with slope of one and intercept of −22%.

Oxygen isotope fractionation between CO2 and water, and the isotopic composition of marine atmospheric CO2
Y. Bottinga,Harmon Craig +1 more
TL;DR: The fractionation factor for oxygen isotope exchange between CO 2 and liquid water has been measured as 1.0409 ± 0.0002, in agreement with the recent value of O'Neil and Epstein this article.
