Abstract:

Arsenic (As) contamination of soils is a major environmental problem due to its toxic and carcinogenic nature. Historical use of As-containing pesticides has resulted in the contamination of soils with high and variable concentrations of As in many parts of Australia. Phytoremediation using As-hyperaccumulating ferns can be potentially utilised as an environmental friendly and low-cost remediation technology to phytoextract As from soils at sites containing elevated and varying concentration of As. The spatial variability of total and phosphate-extractable As concentrations was evaluated in so

Abstract:

An environmentally-based systems approach to sustainability analyses of organic fruit production systems in New Zealand. This research introduces an approach for the assessment of the sustainability of farming systems. It is based on the premises that sustainability has an environmental bottom line and that there is very limited substitutability between natural capital and other forms of capital. Sustainability assessment is undertaken through analyses of energy and material flows of the system and their impacts on the environment. The proposed sustainability assessment approach is based on tw

Abstract:

The health of the environment is integral to the health and wellbeing of the people. When the balance between Atua, whenua and tangata is disrupted, desecrated, disturbed or violated, it can have a detrimental impact on these relationships. This research study explored alternative indigenous paradigms for conceptualizing an environmental health framework that would improve the potency and health of all living things. A key question of the research study was to explore how Ngati Kuri sought to strengthen their relationship and connection with the natural world. The Hapu established Te Tai O

Abstract:

Irish agriculture is becoming increasingly regulated, with restrictions on fertiliser application rates and stocking rates to reduce nitrate (NO₀⁻) leaching losses. However these regulations have been, to date, based on minimal field research. The purpose of this study was to determine the actual leaching losses of nitrate from Irish dairy pasture at a range of stocking rates, and to investigate the effectiveness of the nitrification inhibitor DCD at reducing nitrate leaching losses where these are deemed excessive. In grazed pastures, a major source of leached nitrate is the urine patch, whe

Abstract:

Despite the importance of a high white clover (Trifolium repens) content in temperate pastoral systems in terms of livestock performance and nitrogen fixation, the proportion of white clover in grass-clover pastures is often low (<20%). This thesis examined in two experiments whether the white clover content of pastures could be improved by sowing white clover with alternative grass species to diploid perennial ryegrass (Lolium perenne L.). In a pasture experiment, DM production, pasture composition and morphology of grass-clover mixtures was measured over the establishment year (January 2007

Abstract:

Utilizing environmental DNA (eDNA) for the detection of species in the field is a potentially cost-effective and time-saving technology that may be useful in understanding the distribution and abundance of threatened or endangered species such as the Eastern Massasauga (Sistrurus catenatus). I describe the development of an eDNA assay for the species and evaluate its ability to detect eDNA in laboratory and field conditions. In the field samples, I also investigated the potential for abiotic conditions to influence eDNA detection. Species-specific primers and probe were designed to amplify a 1

Abstract:

Many animal species invest in extended parental care for their offspring. Parental care is costly, and natural selection favors investment strategies which maximize reproductive success. Biparental care is relatively rare, but when it does occur it has been found to increase success in terms of offspring survival and growth and in terms of future reproductive opportunities. In burying beetles (<i>Nicrophorus</i> spp.), both male and female participate in extended parental care. However, the fitness benefits of biparental care in burying beetles have been difficult to establish, with some studi

Abstract:

The East Barmoya and adjoining catchments in coastal central Queensland are suffering classic symptoms of dryland salinity, brought on by clearing of dry-rainforests in their upper catchments. The problem became manifest in the 1920-30s, expanded rapidly in the 1950s and has intermittently increased until the present, lagging some 20 to 30 years behind the period of large scale clearing in the catchment. Plant succession onto the new saline environment is considered, and a production system involving marine couch (Sporobolus virginicus) and swamp-oak (Casuarina glauca) is advocated. The role o

<p dir="ltr">The symbiotic association of scleractinian corals with Symbiodinium has been well studied. Until now, very little attention has been given to the symbiotic associations of soft corals with Symbiodinium. Further, soft coral resistance to heat stress (one type of bleaching) has not been well described despite soft coral abundance exceeding that of scleractinian corals within some coral reefs. The aims of this thesis were to compare and contrast soft corals Sarcophyton ehrenbergi, Sinularia sp. and Xenia sp. to scleractinian corals Acropora hyacinthus, Favites complanata and Porites

Saltmarshes are an intriguing ecotone representing the transition between the marine and terrestrial environments. Much is understood in terms of zonation and vegetation communities in saltmarshes, however considerably less is understood about their edaphic factors. In Australian saltmarshes, terrestrial arthropod fauna and factors that determine invertebrate assemblages are largely unknown. The aim of this study was to understand the factors that influence the presence of epigeal spiders and beetles in a coastal saltmarsh.

The land-grant university system was founded in the 19th century as a public means to help improve people’s everyday lives. A century and a half later, the challenges that the public faces to live a quality life are constantly changing, creating a need for the land-grant system to respond and adapt to continue to fulfill its mission. While the literature contains a wealth of conceptual papers addressing the role and mission of land-grant universities, relatively few papers could be found that reported empirical data or proposed and tested metrics for public engagement constructs.
