Abstract:

In 2008, New Zealand’s gross domestic product (GDP) was four times the size of Uruguay’s, and its export earnings were five times Uruguay’s. Nevertheless, agricultural products accounted for over 60% of export earnings for both economies. This highlighted the importance that the agricultural sectors of Uruguay and New Zealand had to their respective foreign trade sectors. The success with which both countries’ agricultural sectors solved their financial needs would be influential to their export sectors and overall economies. Through the use of expert interviews, a multiple-case study strategy

Abstract:

Lipases from two New Zealand commercial fish species, Chinook salmon (Oncorhynchus tshawytscha) and New Zealand hoki (Macruronus novaezelandiae) were investigated. The lipases were extracted from the pyloric ceca and purified by affinity chromatography and gel filtration. Calcium ions and sodium cholate were absolutely necessary both for lipase stability in a polyacrylamide gel and for optimum activity against p-nitrophenol esters. Both fish lipases had a pI value of 5.8 ± 0.1, were most active at 35°C, were thermally labile, had a pH optimum of 8-8.5, were more acid stable compared to other f

Abstract:

This study explores issues arising from the adoption of the term 'clean and green' for marketing New Zealand dairy products. Three dimensions of environmental quality were investigated: that of sustainable dairying and best practice for the benefit of farmers and the industry; resource management legislation and being a 'good neighbour'; and export marketing opportunities and issues. The study was undertaken during a time of major structural upheaval in the dairy industry, including yearly company amalgamations in the study area, rapid conversion of farmland to dairying, as well as factory ex

For a small state such as New Zealand, trade and economic partnerships are extremely important for economic survival. However, the tyranny of distance complicates this somewhat.

Abstract:

In our ever more populated world, the rapid expansion and intensification of agriculture is driving worldwide biodiversity loss, and the interactions between production landscapes and wildlife conservation are becoming increasingly important. Farming systems depend on ecosystem services such as biological control, while conservationists are calling for the establishment of conservation initiatives in non-preserve landscapes. Despite this, the goals of agriculture and the goals of predator-conservation are rarely mutual. Here, I demonstrate one of the first examples of a mutually beneficial sce

Abstract:

Agricultural adaptation to climate change is often simulated by changes in land use over time. Land use is commonly optimised in economic models, which rests on the neoclassical economic assumption of rational choice among farmers. A wealth of experimental and empirical evidence demonstrates that rational choice can be a poor approximation of human decision making. Models simulating adaptation by optimising producers’ behaviour are in effect simulating adaptive potential. Much evidence demonstrates that adaptive potential does not necessarily translate into adaptation. This investigation focus

Abstract:

Agriculture is key to New Zealand�s economy with land-use conversions in response to market forces occurring regularly. Recently, high-intensity dairy farming has replaced low-density livestock farming, often degrading surrounding waterways. Of particular concern is that dairy cattle can be a source of the parasite Giardia, which in humans is a common cause of gastrointestinal infection. Thus, this thesis evaluated whether dairy farm conversions posed significant consequences for public health. First I examined the prevalence of Giardia in calves in a rapidly intensifying dairying region of

This was achieved by focusing in two of the main conservation issues for this species, the need for standardised and robust monitoring techniques to detect trends and changes in populations, and the determination of the prevalence of chytridiomycosis, caused by the amphibian chytrid fungu

Abstract:

Macroinvertebrate data collected from 120 headwater streams in New Zealand were used to test the ability of the Freshwater Environments of New Zealand River Classification (FWENZ) to explain spatial variation in unimpacted stream invertebrate communities. FWENZ is a GIS based multivariate river environment classification of the sections of national river network. The classification performance of the FWENZ was examined to determine the optimum classification level which could be used for the purpose of conservation and biomonitoring of New Zealand rivers and streams. The classification perform

Abstract:

Take-all, caused by the soilborne fungus, Gaeumannomyces graminis var. tritici (Ggt), is an important root disease of wheat that can be reduced by take-all decline (TAD) in successive wheat crops, due to general and/or specific suppression. A study of 112 New Zealand wheat soils in 2003 had shown that Ggt DNA concentrations (analysed using real-time PCR) increased with successive years of wheat crops (1-3 y) and generally reflected take-all severity in subsequent crops. However, some wheat soils with high Ggt DNA concentrations had low take-all, suggesting presence of TAD. This study investiga

Abstract:

The conservation of marine mammals relies on the knowledge of species ecology in order to assess the impacts of anthropogenic activites and make appropriate species management decisions. Blubber biopsies are a relatively non-invasive sampling protocol to provide ecological information; two particular uses are for dietary analysis via fatty acid signature analysis (FASA) and investigating the uptake of organochlorine (OC) and polychlorinated biphenyl (PCB) environmental contaminants. Blubber composition and structure may vary according to body site and depth due to its dynamic functioning. This

Abstract:

The native plant communities of Canterbury, South Island, New Zealand have been severely modified and degraded and the Canterbury Plain (750,000 ha) retains few remnants of its original forest and other ecosystems. The research presented here considers the mutualistic roles of exotic and indigenous species in the process of restoring degraded landscapes. Exotic species may have an important role in the (re) establishment of desired indigenous species, and may influence succession through to a forest dominated by them. One aspect of this work describes indigenous plant community regeneration fa

Abstract:

The eco-epidemiology of bovine tuberculosis (Tb) in wild deer (mainly red deer Cervus elaphus) in New Zealand was investigated. Bovine Tb is caused by Mycobacterium bovis. Specific aims were to clarify the likely routes of infection in deer, and to determine the status of deer as hosts of Tb, the likely rates and routes of inter- and intra-species transmission between deer and other wildlife hosts, the role of deer in spreading Tb, and the likely utility of deer as sentinels of Tb presence in wildlife. As the possum (Trichosurus vulpecula) is the main wildlife host of Tb, the research also inc

Abstract:

In this study, buckwheat (Fagopyrum esculentum Moench) and alyssum (Lobularia maritima (L.)) flowers were used to examine the effect of floral resources on the efficacy of the leafroller parasitoid Dolichogenidea tasmanica (Cameron) in vineyards. This was done by assessing the influence of these flowers on parasitoid abundance and parasitism rate, and by investigating the consequences of this for leafroller abundance. In laboratory experiments, alyssum flowers were used to investigate the effect of floral food on the longevity, fecundity and sex ratio of D. tasmanica. Dolichogenidea tasmanica

Abstract:

Inherited rickets of Corriedale sheep is a newly discovered skeletal disease of sheep with simple autosomal recessive inheritance. The clinical signs resemble rickets in other species and include decreased growth rate, thoracic lordosis and angular limb deformities. Radiographic features include physeal thickening, blurred metaphyseal trabeculae and thickened porous cortices. Computed tomography scanning of long bones reveals increased bone mineral content and cortical area, but decreased bone mineral density. Gross lesions include segmental thickening of physes, growth arrest lines, collapse

Abstract:

Neo-liberalism has become the dominant approach to economic development since the 1980s. Based on the economic principle of “efficiency”, the Washington Consensus and its supporters have avidly promoted the neoliberal orthodoxy as the ideal blueprint for the economic development of all countries in every region. However, as this thesis has discovered, the efficiency of public policy is weighed not by its conformity to an ideology but on how effective it responds to the economic and social problems of the population in question. In recent years Tonga has endured severe economic shocks which hav
