Examining Pathways for Water Loss from Mountain Lake, Giles County, Virginia
… Lake has a documented history of dramatic water level fluctuations. Previous water balance studies have documented that the main cause of water loss is outflow to groundwater. However, the flow paths of water exiting the lake are unknown. This study applied hydrologic, geophysical, and dye …

Novel water-use strategies of Colorado wetland plants: implications for wetland water loss
… is a tension between wetland restoration and water rights. Wetlands, relied upon by humans and wildlife alike, also contribute significantly to evapotranspiration (ET) due to higher water tables and dense vegetation. It is therefore critical to understand how much water wetlands lose to …

Apparent water loss due to consumer meter inaccuracies in selected areas of South Africa
Apparent losses form an important component of the International Water Association's water balance. While apparent losses look like real losses to a municipality, this is not actually the case. The main components of apparent losses are water meter under-registration and unauthorised consumption. …

Effects of temperature on gular fluttering and evaporative water loss in four sympatric cormorants in southern Africa
… heat but expensive in terms of evaporative water loss. This study examined gular fluttering behaviour of four species of southern African cormorants, crowned ( Microcarbo coronatus ), Cape ( Phalacrocorax capensis ), bank ( Phalacrocorax neglectus ), and white-breasted ( Phalacrocorax …

The Physiological and Behavioural Consequences of Reduced Scalation in Captive-bred Phenotypes of the Bearded Dragon (Pogona vitticeps Ahl 1926)
… scaled integument and low rates of evaporative water loss. Whether or not there is a causal relationship between the two has been a contentious issue. There also remains the question of whether the lepidosaur scale forms a barrier to ultraviolet (UV) light. Thirdly, there is evidence to suggest …

Applications of Melt Inclusions to Problems in Igneous Petrogenesis
… problem associated with melt inclusions is water-loss during laboratory heating. A Raman spectroscopic technique was developed to determine water contents of silicate glasses, and this technique was applied to monitor water loss from natural melt inclusions that were heated for varying …

Can Batch Reverse Osmosis Make Desalination More Affordable and Sustainable?
… (RO) desalination can help to ensure secure water resources, but the process remains costly. From 2007-2017, global desalination capacity nearly doubled, from 47 to 92 million m3 /day, with RO accounting for two thirds of installed capacity. Despite this growth, the total volume of treated …

Moisture stress conditioning, potassium nutrition, and tolerance of Salvia splendens 'Bonfire' to moisture stress
… of this study was to determine the leaf water relations, gas exchange, and growth of the bedding plant salvia Salvia splendens 'Bonfire‘ as influenced by moisture stress conditioning (MSC - exposing plants to 4 sublethal dry-down cycles) and potassium (K) nutrition. Plants were fertilized …

Active leakage management with bayesian networks
… implementation in most developing countries’ Water distribution systems (WDS’s) remain limited. This is attributed to some limiting challenges to leakage management faced by these WDS. Some of these include; financial constraints, poor record-keeping systems, and inadequate …

A theoretical and empirical framework for measuring minimum conductance, an understudied plant drought trait
… (gmin) describes the residual rate of water loss by a plant through its leaves when it has closed its stomata in order to minimise that water loss rate. This includes contributions to water loss through incompletely closed or leaky stomata, the waxy cuticle layer, or through wounding …

Overwintering biology of the brown marmorated stink bug, Halyomorpha halys (Hemiptera: Pentatomidae)
… Moreover, overwintering H. halys maintain their water balance through a reduction of water loss rates, while conserving energy stores (lipids and carbohydrates). This is consistent with lab-reared-diapausing H. halys who exhibit reduced water loss rates and temperature-independent metabolic …

Aspects of the energetics and renal physiology of some African arid-adapted rodents
… on thermoregulation, metabolism, evaporative water loss and thermal conductance was studied in the North East African pigmy gerbil, gerbillus ppusillus; This gerbil did not strictly maintain homoeothermy and like most arid-adapted rodents had a reduced basal metabolic rate. When G. pusillus …

Soybean transpiration, vegetative morphology, and yield components following simulated and actual insect defoliation
… growth, development, yield, and yield components;Water loss from potted soybean after defoliation by simulation methods and actual insects demonstrated significant, but transitory, differences during the first 16 hours. Total water loss over three days did not differ between simulated and actual …

Physiological and behavioural responses to temperature and humidity in fossorial amphibians
… on the thermal sensitivity of metabolism and water loss in Ambystoma maculatum. My findings suggested that acute changes in temperature affected energy and water budgets. However, acclimatory changes in temperature affected metabolism but not water loss. I then examined how temperature (17°C …

Life in the Dirt: Factors Influencing the Behavior and Distribution of Spea Intermontana in Eastern Washington State
… study explored the effects of temperature and water level on the rate of metamorphosis. We gathered data on rates of development, survival, body mass, snout-vent length, and hind leg length of metamorphs under 4 treatments: 20C x High Water, 30C x High Water, 20C x Water Loss, and 30C x Water …

Comparative water relations of indigenous and invasive Australian Proteaceae in fynbos
Water-use efficiency (WUE) as reflected in the leaf carbon stable isotope ratio was compared between co-occurring indigenous fynbos proteoids and invasive Australian hakeas H. sericea, H. gibbosa and H. suaveolens. At the driest site, H. suaveolens was slightly more WUE than several co-occurring …

Physiological Bases and a Novel Genetic Determinant of Water-Use Efficiency (WUE)
<p>Water-use efficiency (WUE), the ratio of biomass to water loss, is a heritable but complex trait, the genetic basis of which is largely unknown. We utilized diverse accessions of the halophyte <em>Eutrema salsugineum </em>to ultimately identify a novel genetic determinant of WUE. <em>E. …
