Lucas A. Cernusak,Nerea Ubierna,Klaus Winter,Joseph A. M. Holtum,Joseph A. M. Holtum,John D. Marshall,John D. Marshall,Graham D. Farquhar +7 more
TL;DR: The effective use of Δ across its full range of applications will require a holistic view of the interplay between environmental control and physiological modulation of the environmental signal.
Book ChapterDOI
Sources of Variation in the Stable Isotopic Composition of Plants
TL;DR: The most common applications of stable isotopes in plant ecophysiology have been discussed in this article, where they have been used in a wide range of applications, such as photosynthetic and ecophysiological differences.
Journal ArticleDOI
Altitude trends in conifer leaf morphology and stable carbon isotope composition
TL;DR: It is concluded that species specificity of the isotopic shift indicates that evergreen conifers demonstrate varying degrees of functional plasticity across environmental gradients, while the observed convergence of δ13C with LMA suggests that internal resistance may be the key to understanding inter-specific isotopic variation across altitude.
Journal ArticleDOI
The relationship between tree height and leaf area: sapwood area ratio.
Nate G. McDowell,Holly R. Barnard,Barbara J. Bond,Thomas M. Hinckley,Robert M. Hubbard,Robert M. Hubbard,Hiroaki Ishii,Barbara Köstner,Federico Magnani,John D. Marshall,Frederick C. Meinzer,Nathan Phillips,Michael G. Ryan,Michael G. Ryan,David Whitehead +14 more
TL;DR: The decrease in Al:As with increasing tree size that was observed in the majority of species may be a homeostatic mechanism that partially compensates for decreased hydraulic conductance as trees grow in height.
Journal ArticleDOI
Differential uptake of summer precipitation among co-occurring trees and shrubs in a pinyon-juniper woodland
TL;DR: In this paper, the authors measured the deuterium to hydrogen (D/H) ratio in stem xylem water to determine the relative uptake of summer precipitation by four cooccurring plant species in southern Utah.
