Phreatophyte.

As a facultative phreatophyte and halophyte, tamarisk has a competitive advantage over native, obligate phreatophytes (e.g. cottonwood and willow) in areas where salinities are elevated or water tables depressed, conditions characteristic of disturbed riparian environments [44,115,165,170,181,211,212].Abstract. Ozone formation regimes are closely related to the ratio of volatile organic compounds (VOCs) to NOx. Different ranges of HCHO/NO2 indicate three formation regimes, including VOC-limited, transitional, and NOx-limited regimes. Due to the unstable interactions between a diversity of precursors, the range of the transitional regime, which …Definition of phreatophyte in the Definitions.net dictionary. Meaning of phreatophyte.

The correct answer is option 3. i.e. Phreatophytes are the plants adapted to grow in arid environments.. Phreatophytes are the deep-rooted plants to obtain water from deep inside the ground.; They are named so because they are derived water from the phreatic zone below the water table.; Extension of roots is an adaptation through which the desert plants are able to obtain water even in the dry ...A phreatophyte is a deep-rooted plant that obtains a significant portion of the water that it needs from the phreatic zone (zone of saturation) or the capillary fringe above the phreatic zone.

What is an example of a Phreatophyte? Examples of phreatophytes include Welwitschia and mesquite: Prosopis glandulosa. The alfalfa, or Medicago sativa, is a widespread phreatophyte plant of great economic value. Trees like the ash, the alder, the willow and the poplar are also useful in this regard.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 concentration [5,8 ...

Dermatophyte definition: any parasitic fungus that affects the skin | Meaning, pronunciation, translations and examplesEvapotranspiration rates and the ground water component of evapotranspiration at a site in Colorado's San Luis Valley that is dominated by shrubby phreatophytes (greasewood and rabbitbrush) were compared before and after a water table drawdown. Evapotranspiration (ET) rates at the site were first measured in 1985–1987 …This facultative phreatophyte tolerates moderately saline conditions or xeric, nonsaline upland sites with shallow water tables. Its limited but varied salt tolerance and high drought tolerance interact to control water stress and define the broad habitat boundaries of the alliance. This is one of the most widespread saltbush alliances in the ...The strong hydrotropism (groundwater-dependent) and flexible water-use strategy of T. ramosissima and P. euphratica help both species survive in hyperarid climates. The differences in the developmental environments between T. ramosissima and P. euphratica can be explained well by the different distribution characteristics of root profiles. That is, higher root plasticity helps T. ramosissima ...Another class of desert plant is the phreatophyte. These have adapted to the environment by the development of long taproots that penetrate downward until they approach the assured water supply provided by groundwater. Among these plants are the date palm, tamarisk, and mesquite. They commonly grow near stream channels, springs, or on the …

As a facultative phreatophyte and halophyte, tamarisk has a competitive advantage over native, obligate phreatophytes (e.g. cottonwood and willow) in areas where salinities are elevated or water tables depressed, conditions characteristic of disturbed riparian environments [44,115,165,170,181,211,212].

In this phreatophyte-dominated desert, sufficient pre-growing season precipitation leads to more germination and growth of shallow-rooted annual plants. When the soil is subsequently frequently recharged, the herbaceous component will remain active (Reynolds and others 2004 ; Collins and others 2008 ) and strongly affect the carbon balance of ...

The main objective of this review is to disseminate research-based knowledge and improve awareness of this important plant species and provide a framework that could effectively improve regional socio-ecological environments, particularly in controlling desertification ... A phreatophyte is a deep-rooted plant that acquires a significant portion of the water that it requires from the phreatic zone (i.e. the zone of saturation) or the capillary fringe right above the phreatic zone. Phreatophytes are those plants that are supplied with surface water and often have their roots continuously in touch with the moisture.Methods To demonstrate HR, we present data on patterns of sap flow in the stems or branches and lateral roots of those two phreatophyte species and soil volumetric moisture content where these ...Declining water levels and reduced natural discharge at springs, seeps, and phreatophyte areas primarily are the result of decades of groundwater development in the Death Valley regional flow system, in Nevada and California. A calibrated groundwater-flow model was used to simulate potential future effects of groundwater pumping on water levels and natural groundwater discharge in the study area.This facultative phreatophyte tolerates moderately saline conditions or xeric, nonsaline upland sites with shallow water tables. Its limited but varied salt tolerance and high drought tolerance interact to control water stress and define the broad habitat boundaries of the alliance.

Although much is known about water ...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 ...A small number of species called phreatophytes have root systems capable of reaching deep into groundwater supplies. That helps them survive in arid and semiarid climates …Phreatophyte. a plant with an extremely deep root system that uses groundwater as its source of moisture. A classical example is the date palm ( Phoenix dactylifera ), which grows on oases in the Sahara and the Arabian Peninsula. (An ancient Arabic proverb says that the date palm has its head in fire and its feet in water.)

In the case of this facultative phreatophyte, continuous groundwater availability throughout the season might assure the LS elongation. However, the greater elongation of such shoots was observed during the driest years with scarce spring precipitation (2017), in contrast to FBs that extended more during the wet spring of 2018 (Figure 3).Of phreatophyte communities near analyzed wells, 48% and 57% were near wells with declining trends in Nevada and Oregon, respectively. Differences among GDE types could reflect more groundwater ...

It is an obligate riparian species [10,58,91,92,93] that grows only where there is abundant surface or ground water ; this includes intermittent, ephemeral, and permanent watercourses [55,133].This study was carried out in the Cuenca de la Independencia, a semi-arid basin in Central Mexico. The objective is to describe the main features of a groundwater flow regime under natural conditions, based on groundwater discharge manifestations.supply, to include the "phreatophyte problem". In fact, it was pointed out by Douglas (1954, p. 8-12) that the word "phreato­ phyte" is becoming a term that the laymen find convenient for designating a group of destructive enemies that formerly were regarded merely as nuisances. ACKNOWLEDGMENTSIn the case of this facultative phreatophyte, continuous groundwater availability throughout the season might assure the LS elongation. However, the greater elongation of such shoots was observed during the driest years with scarce spring precipitation (2017), in contrast to FBs that extended more during the wet spring of 2018 (Figure 3).A systematic synthesis of phreatophytes' responses to groundwater drawdown would provide a more complete picture of groundwater-related research aimed at the sustainable management of groundwater-dependent ecosystems amid climate change.
