“…The TAGY tagging simulation demonstrated that vapor δ values (δ 18 O v ) trace atmospheric circulation over most regions of the western U.S. This particular finding may be useful in the context of the results of Helliker et al [60] who showed through controlled experiments and model calculations that epiphyte Tillandsia usneoides from CAM plants record δ values of vapor. Thus, these plants may be useful in detecting shifts in middle latitude storm tracks [61,62].…”

Many climate proxies in geological archives are dependent on the isotopic content of precipitation (δ 18 O p ), which over sub-annual timescales has been linked to temperature, condensation height, atmospheric circulation, and post-condensation exchanges in the western U.S. However, many proxies do not resolve temporal changes finer than interannual-scales. This study explores causes of the interannual variations in δ O p in California. In the interior of the western U.S., a strong temperature effect was found only after annual mean temperatures were weighted by monthly precipitation totals. These multiple influences on δ 18 O p complicate interpretations of western U.S. climate proxies that are derived from isotopes in precipitation.

“…The δ 2 H and δ 18 O values between plant organic matter and liquid water in both leaf and surrounding environments provide important information on current and past environments (Terwilliger et al, 2002;McCarroll and Loader, 2004;Helliker, 2011).…”

“…δ 13 C of NVP can be used to trace environmental CO 2 gradients (Flanagan et al, 1999;Lakatos et al, 2007;Meyer et al, 2008), whereas fossil bryophytes record ancient CO 2 levels (Fletcher et al, 2005(Fletcher et al, , 2006. Additionally, epiphytic plants function as atmospheric water traps (Helliker and Griffiths, 2007;Helliker 2011). Because epiphytic NVP are commonly in equilibrium with water vapour, it is inferred that δ 18 O of bulk water and organic material might serve as a short and long-term recorder for atmospheric vapour, respectively (Helliker and Griffiths, 2007;Hartard et al, 2008Hartard et al, , 2009).…”

“…Cuntz et al (2007), however, state that comparably good results could also be achieved with different well mixed metabolic pools of water. For epiphytic and non-vascular plants which lack permanent access to soil water, it has been shown that a description of water isotope dynamics requires consideration of distinct water pools as well as water potentials (Helliker and Griffiths, 2007;Hartard et al, 2009;Helliker, 2011).…”

Progress and challenges in using stable isotopes to trace plant carbon and water relations across scales

Abstract. Stable isotope analysis is a powerful tool for assessing plant carbon and water relations and their impact on biogeochemical processes at different scales. Our processbased understanding of stable isotope signals, as well as technological developments, has progressed significantly, opening new frontiers in ecological and interdisciplinary research. This has promoted the broad utilisation of carbon, oxygen and hydrogen isotope applications to gain insight into plant carbon and water cycling and their interaction with the atmosphere and pedosphere. Here, we highlight specific areas of recent progress and new research challenges in plant carbon and water relations, using selected examples covering scales from the leaf to the regional scale. Further, we discuss strengths and limitations of recent technological Published by Copernicus Publications on behalf of the European Geosciences Union. C. Werner et al.: Progress and challenges in using stable isotopesdevelopments and approaches and highlight new opportunities arising from unprecedented temporal and spatial resolution of stable isotope measurements.
