The restoration of riparian plant communities following alien plant clearing in the Western Cape
… of riparian zones controls the flow of water, nutrients and sediments into streams. Plan communities in these habitats are often rish in species, and serve as corridor facilitating the movement of organisms.

Slash Mulching and Incorporation as Mechanical Site Preparation for Pine Plantation Establishment and Subsequent Effects on Soil Moisture and Site Hydrology
… while post-treatment site hydrology and soil water chemistry data was analyzed periodically for one year. Seedling survival and height data were analyzed after one growing season. The treatments had little effect on soil physical properties, site hydrology, soil water nutrients, or seedling …

Removal of Wastewater Nitrogen and Phosphorus by an Oligohaline Marsh
Wetlands potentially contribute to water quality improvement. The objective of this thesis was to determine the role of wastewater processing by oligohaline Council Creek marsh (0.16 km2), which receives wastewater from Easton, MD. Tidal flushing, nutrient distributions, plant uptake, and sediment …

Relay- and double-crop production systems for wheat
… however, the companion crops may compete for water, nutrients, and sunlight, which may slow development of either crop. Relay-intercropped soybean [Glycine max (L.) Merr.] production involves seeding wheat in the fall and an intercrop seeding of soybeans into standing wheat (Triticum aestivum …

Interactive effects of elevated carbon dioxide concentration with nutrient availability and leaf development on plant carbon metabolism
… [CO2] can be dependent on interactions with water, nutrients, and plant developmental processes. The purpose of this thesis is to address fundamental knowledge gaps in understanding plant responses to the interaction between elevated [CO2] with water, nitrogen (N), and leaf developmental …

Development of novel approaches to study Cuscuta campestris biology
… organ that acts as a bridge for the exchange of water, nutrients, macromolecules like mRNA, microRNA, and proteins, and microorganisms. Studies of Cuscuta spp. are challenging due to its dependence on the host and other host influences on the parasite. Recent research has shown intriguing aspects …

The design, construction, and operation of a pilot plant for the production of trichloroacetic acid from acetic acid and chlorine
… the crops produced. Weeds compete with crops for water, nutrients, and light; they help spread diseases; some are poisonous to animals; some disrupt water distribution and flow along waterways and spread their seeds to irrigated land; and they are hazardous and bothersome to train movements when …

A Mycorrhizal Model for Transactive Energy Markets
… the exchange of resources including energy, water, nutrients, and information between trees and plants in forest ecosystems. This work explored MNs as an inspiration for new market models in transactive energy networks, which similarly involve exchanges of energy and information between …

Biosynthesis of copper nanoparticles using a bioflocculant from Alcaligenis faecalis, characterization and its application
… efficient removal of pollutants in the area of water purification. Most common method used for nanoparticles formation such as physical (condensation evaporation) and chemical (oxidation and reduction) are very efficient traditional methods. However, both methods have been found to have some …

ENHANCED SOIL STRUCTURING BENEATH WHITE CLOVER AND ITS IMPACT ON NUTRIENT TRANSPORT
… permeability to air and freer drainage to water. Structural stability tests suggested that white clover improved the ability of the soil to maintain its structure under the action of water, and was estimated to be three times more stable than ryegrass. There was also evidence which implied …

Coupling Treatment Technologies with Bioelectrochemical Systems to Optimize Resource Recovery from Wastewater
Wastewater is a common waste produced from municipal, agricultural, and industrial processes. As the world’s population increases, the amount of wastewater produced globally is expected to reach approximately 450 billion m3 in the next two decades. Issues surrounding water, food, and energy …

The contribution of fog to the moisture and nutritional supply of Arthraerua leubnitziae in the central Namib Desert, Namibia
… Apart from the importance of fog as a source of water for plants, it is also associated with particulates that may contain essential nutrients for plants. Furthermore, dry deposition can be an important input of nutrients to many ecosystems, but without water, dust deposited on leaves or on soil …

Ectomycorrhizal associations in tropical montane forest: insights into their influence on nutrient cycling and functional responses to soil fertility
… through ectomycorrhizal networks that transfer water, nutrients or carbon, and (3) by altering ecosystem nutrient economies, thereby reducing the availability of limiting resources to competing species. After testing these three hypotheses I found no evidence for positive feedback on Oreomunnea …

Characteristics and evolution of a dynamic prograding continental margin: the late Neogene Giant Foresets Formation, northern Taranaki Basin, New Zealand
… and lower slope. Much of the shallowing of water depth in northern Taranaki basin occurred during deposition of bottomset facies. Depositional environments changed from mid/lower bathyal during the Late Pliocene, to upper bathyal during the Waipipian and Mangapanian. However, the most rapid …
