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 …phreatophyte: [noun] a deep-rooted plant that obtains its water from the water table or the layer of soil just above it.Soil nutrients are vital for plant growth and survival and present a crucial role in terrestrial function and productivity. However, little is known about the effect mechanism of groundwater table on soil nutrients in an arid desert ecological system. This study investigated the impacts of groundwater depth on the concentrations of soil organic …We conclude that in P. euphratica, a permanent phreatophyte in the study region, SLA constitutes an acclimatization not only to the water supply from the soil but also - and probably even more importantly - to the local transpirational demand; and that SLA is related to biomass production through optimization of the water use efficiency.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. Phreatophytes are plants that are supplied with surface water and often have their roots constantly in touch with moisture.

Tamarix (Tamaricaceae), a phreatophyte genus from the Old World, is a tenacious competitor which has invaded North America (namely the United States and Mexico), Australia, and South Africa amongst other countries. Biological control of invasive Tamarix taxa in South Africa is complicated by the indigenous T. usneoides, which is phylogenetically distant from the invasive T. chinensis ...The relationship between groundwater recharge and discharge is one of the most important aspects in the protection of ecologically valuable areas. Knowledge of groundwater systems is therefore a pre-requisite for up-to-date integrated land and water management.

Desert annuals are plants that adapt to desert conditions by completing their lifecycle when there is sparse rainfall, and then all the parts of the plant die. The desert annuals grow, the flower produces seeds and then dies. The seeds lie dormant until the conditions are favorable for growth.Soil moisture–plant interactions are more obvious in water-limited regions where soil moisture is the limiting factor. Recent studies (e.g. García-Santos et al. 2009; Ghimire et al. 2014; Jiao et al. 2016) have investigated the effects of specific plant species on the water cycle but over short time scales, such that the results were not always …However, the growth strategy and responses to nutrients and water of young phreatophyte seedlings before their roots reach the water table are poorly understood, especially in the scenarios of nitrogen (N) deposition and drought.

It is found growing at elevations between 1,600-7,200' on open, rocky grasslands where they visually dominate the landscape. Mature individuals usually reach around 15-30' tall ...Assessing hydrologic effects of developing groundwater supplies in Snake Valley required numerical, groundwater-flow models to estimate the timing and magnitude of capture from streams, springs, wetlands, and phreatophytes. Estimating general water-table decline also required groundwater simulation.

Palo verde trees need to be propagated from seeds rather than cuttings. The seeds will benefit from being carefully scarified and then soaked in hot water overnight before immediately sowing them. The seeds will need to be kept moist, warm, and lightly shaded while germinating.While seasonal redistribution of fine root biomass in response to fluctuations in groundwater level is often inferred in phreatophytic plants, few studies have observed the in situ growth dynamics of deep roots relative to those near the surface. We investigated the root growth dynamics of two Banksia species accessing a seasonally dynamic water table and hypothesized that root growth ...Increased groundwater demand is causing aquifer declines that impact viability of groundwater-dependent ecosystems (GDEs) like springs and phreatophyte communities. To understand which springs and phreatophyte communities may be stressed by groundwater level declines in Oregon and Nevada, we assessed groundwater level trends in nearby monitoring wells. Very few springs and phreatophyte ...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.Jul 7, 2022 · Calligonum mongolicum is a phreatophyte playing an important role in sand dune fixation, but little is known about its responses to drought and P fertilization.
