Hydrographs from shallow wells in vegetated riparian zones frequently display a distinctive pattern of diurnal water table fluctuations produced by variations in plant water use. A multisite investigation assessed the major controls on theseDifferent microclimates can have significant impact on the physiology of succulents that inhabit arid environments such as the Mojave Desert (California). We investigated variation in leaf physiology, morphology and anatomy of two dominant Mojave Desert monocots, Yucca brevifolia (Joshua tree) and Hesperoyucca whipplei, growing along a soil water availability gradient. Stomatal conductance (gs ...Arid climate restricts this phreatophyte to moist areas [51,159]; desert-willow is an obligate outwash or riparian species [13,19,39,53,54,102,157].

Alhagi sparsifolia Shap., a dominant perennial phreatophyte grown at the southern rim of the Taklimakan Desert, has an important influence on wind prevention and sand fixation in the local ecosystem. A. sparsifolia is a leguminous plant and is an economically important species for local livestock because of its high protein ...The short-term and long-term ecological responses of phreatophyte communities to water table change have rarely been investigated. Phreatophytes respond in a variety of ways to water table decline, but both the magnitude and rate of water table decline can affect vegetation, and thus ET response.

Phreatophyte consumption of groundwater has also been estimated using the water balance residual from field studies in which the other components of the water balance have been calculated from monitoring data [Weeks and Sorey, 1973]. However, the large uncertainty regarding subsurface inflows and outflows, among other aspects of the water ...1. 3. 2023 ... In botany, the term phreatophytes refers to plants that usually obtain the water necessary to grow from areas at a high depth of the soil.

Phreatophyte control application on salt cedars initially reduced ET by approximately 20 to 35percent but the reduction was only 10 percent in the subsequent month in response to the understory growth.

We investigated hydraulic constraints on water uptake by velvet mesquite (Prosopis velutina Woot.) at a site with sandy-loam soil and at a site with loamy-clay soil in southeastern Arizona, USA. We predicted that trees on sandy-loam soil have less negative xylem and soil water potentials during drought ...Phreatophytes are plants that depend for their water supply upon ground water that lies within reach of their roots. Although not confined to the arid regions of the Western United States, their occurrence there is more common, more spectacular, and, because of their effect on water supply, more important than it is in humid and subhumid regions.
