Phreatophyte
Evapotranspiration (ET) of groundwater may occur when the water table is close to the land surface or when phreatophytes draw water from below the water table. The Evapotranspiration Package requires the user to assign a maximum ET rate (RETM) to each cell from which ET may occur. The maximum rate is used when the water table in a cell equals ...Ecological stoichiometry is an important aspect in the analysis of the changes in ecological system composition, structure, and function and understanding of plant adaptation in habitats. Leaf carbon (C), nitrogen (N), and phosphorus (P) concentrations in desert phreatophytes can be affected by diff …

Phreatophyte Evapotranspiration and Its Potential Reduction Without EradicationPhreatophytes 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. Given the significance of root dynamics for phreatophyte adaptation to water stress, this study attempted to analyze the effect of root interactions with groundwater on the model-simulated ET dynamics in a field site dominated by Tamarix ramosissima, a typical groundwater-dependent plant in arid regions.Title English: phreatophytes ; Definition English: Water-loving plants that grow mainly along stream courses and/ or where their roots reach the capillary fringe ...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. 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. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, the ecophysiological effects of groundwater drawdown ...Cost. $6 per ton.

This USGS report presents the results of a field experiment that measured the water budget and vegetation characteristics of the area. Find out how this study contributes to the understanding of hydrologic processes and management of water resources in arid regions.The information generated in this work represents an initial step for further research to understand the controlling environmental factors on phreatophyte trees root architecture within the complexity of natural habitats, the internal regulation of root responses to environmental cues, and the consequences for water and nutrient cycling and ...Our analysis of groundwater level data, soil profiles, and vegetation characteristics at two typical phreatophyte-dominated sites (Tamarix ramosissima and Populus euphratica) located in hyper-arid desert environments in northwestern China indicates that groundwater evapotranspiration is an important factor that controls …An equation describing the mean daily discharge of groundwater by transpiration from phreatophyte shrubs as a function of plant density, leaf area index, and depth to groundwater was developed using an energy combination model calibrated with energy fluxes calculated from micrometeorological data. The energy combination model partitions the energy budget between the soil and canopy permitting ...

Culler et al. s 1982) reported that (phreatophyte removal from river floodplains in Arizona reduced phreatophyte consumption of PMID: 16356903. 10.1093/treephys/26.3.313. 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 ...

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 …6 mins to read. Larrea tridentata is a plant that is also known as creosote bush, greasewood, chaparral, and gobernadora in the Mexican desert and it can survive extreme drought while growing healthy bushes.

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. ACKNOWLEDGMENTSDeclining 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.
Abstract: Desert phreatophytes are greatly dependent on groundwater, but how their root systems adapt to dif- ferent groundwater depths is poorly understood ...The results indicate that groundwater recharge accounts for only 21.16% of the precipitation, while 72.54% is lost in the form of evapotranspiration. The annual-lumped groundwater recharge rate decreases in the order of cropland, grassland, urban land, and forest. Land use change has resulted in a decrease of 4 × 106 m3 of yearly groundwater ...
