Mechanisms of plant survival and mortality during drought: why do some plants survive while others succumb to drought?
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.
Water Relations of Plants and Soils
This book is a useful introduction for students, teachers, and investigators in both basic and applied plant science, including botanists, crop scientists, foresters, horticulturists, soil scientists, and even gardeners and farmers who desire a better understanding of how their plants grow.
Survey and synthesis of intra‐ and interspecific variation in stomatal sensitivity to vapour pressure deficit
Responses of stomatal conductance (gs) to increasing vapour pressure deficit (D) generally follow an exponential decrease described equally well by several empirical functions. However, the magnitude…
Global convergence in the vulnerability of forests to drought
It is shown that 70% of 226 forest species from 81 sites worldwide operate with narrow hydraulic safety margins against injurious levels of drought stress and therefore potentially face long-term reductions in productivity and survival if temperature and aridity increase as predicted for many regions across the globe.
A method for measuring hydraulic conductivity and embolism in xylem
Abstract Hydraulic conductivity of the xylem is computed as the quotient of mass flow rate and pressure gradient. Measurements on excised plant stems can be difficult to interpret because of…
Vulnerability of Xylem to Cavitation and Embolism
Embolism Formation by Winter Freezing, Water Stress-Induced Embolism, and more.
Trends in wood density and structure are linked to prevention of xylem implosion by negative pressure
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.

Xylem Embolism in Ring‐Porous, Diffuse‐Porous, and Coniferous Trees of Northern Utah and Interior Alaska
Differences between sites in northern Utah and interior Alaska were explained by vulnerability to embolism caused by freeze-thaw cycles, whereas most conifers were entirely resistant, whereas dicot trees were vulner- able.
Vulnerability to xylem cavitation and the distribution of Sonoran Desert vegetation.
It is suggested that cavitation vulnerability limits plant distribution by defining maximum drought tolerance across habitats and influencing competitive ability of drought tolerant species in mesic habitats.
