Mechanisms of plant survival and mortality during drought: why do some plants survive while others succumb to drought?
Nate G. McDowell,William T. Pockman,Craig D. Allen,David D. Breshears,Neil S. Cobb,Thomas Kolb,Jennifer A. Plaut,John S. Sperry,Adam G. West,Adam G. West,David G. Williams,Enrico A. Yepez +11 more
TL;DR: A hydraulically based theory considering carbon balance and insect resistance that allowed development and examination of hypotheses regarding survival and mortality was developed, and incorporating this hydraulic framework may be effective for modeling plant survival andortality under future climate conditions.
Journal ArticleDOI

Brendan Choat,Steven Jansen,Timothy J. Brodribb,Hervé Cochard,Hervé Cochard,Sylvain Delzon,Radika Bhaskar,Sandra Janet Bucci,Taylor S. Feild,Sean M. Gleason,Uwe G. Hacke,Anna L. Jacobsen,Frederic Lens,Hafiz Maherali,Jordi Martínez-Vilalta,Stefan Mayr,Maurizio Mencuccini,Patrick J. Mitchell,Andrea Nardini,Jarmila Pittermann,R. Brandon Pratt,John S. Sperry,Mark Westoby,Ian J. Wright,Amy E. Zanne,Amy E. Zanne +25 more
TL;DR: In this article, the authors draw together published and unpublished data on the vulnerability of the transport system to drought-induced embolism for a large number of woody species, with a view to examining the likely consequences of climate change for forest biomes.
Journal ArticleDOI
Vulnerability of Xylem to Cavitation and Embolism
Melvin T. Tyree,John S. Sperry +1 more
TL;DR: Embolism Formation by Winter Freezing, Water Stress-Induced Embolism, and more.
Journal ArticleDOI
Trends in wood density and structure are linked to prevention of xylem implosion by negative pressure
TL;DR: The more drought-tolerant the plant, the more negative the xylem pressure can become without cavitation, and the greater the internal load on thexylem conduit walls, and Dt was correlated with cavitation resistance.
Journal ArticleDOI
Survey and synthesis of intra- and interspecific variation in stomatal sensitivity to vapour pressure deficit
Ram Oren,John S. Sperry,Gabriel G. Katul,Diane E. Pataki,Brent E. Ewers,Nathan Phillips,Karina V. R. Schäfer +6 more
TL;DR: In this paper, the authors analyzed data from a variety of sources employing both porometric and sap flux estimates of stomatal conductance (gs) to evaluate the hypothesis that stomata sensitivity is proportional to the magnitude of gs at low D (£ 1k Pa).
