(Thesis, Doctor of Philosophy, 2013)The objective of this thesis was to improve our understanding of the processes and mechanisms underlying the successful invasion of Thymus vulgaris L. in Central Otago, New Zealand by carrying out aboveground and belowground ...
-
(Thesis, Doctor of Philosophy, 2013)Cysteine dioxygenase (CDO) is a non-heme mono-iron enzyme that catalyses the oxidation of cysteine to cysteine sulfinic acid (CSA) by the addition of the two oxygen atoms from dioxygen to the thiol group of cysteine. In ...
-
(Thesis, Doctor of Philosophy, 2013)In contrast to advanced stages of oogenesis, the endocrine regulation of early stages of oocyte growth has received little attention. In oviparous vertebrates, particularly in teleost fish, the early stages of oogenesis ... -
(Thesis, Doctor of Philosophy, 2013)Intertidal ecosystems are characterized by periodic variations in the water column throughout tidal cycles, a situation that can induce changes in the physiological balance of organisms that live there. If low tide occurs ...
-
(Thesis, Doctor of Philosophy, 2013)Two randomised controlled trials, published in the early 1990s, proved that periconceptional use of folic acid containing supplements reduces the risk of a neural tube defect (NTD)-affected pregnancy. In New Zealand in ...
-
(Thesis, Master of Science, 2013)Talent is valued and enjoyed in the community, yet research emphasis has been on identifying and developing elite talent, usually in children. Scant information exists about talent in an adult general population. A ...
-
(Thesis, Doctor of Philosophy, 2013)Juveniles have limited foraging ability compared to adults, due to physiological, morphological and behavioural constraints that ultimately affect their fitness and survival. Therefore, constraints on juvenile foraging ... -
(Thesis, Doctor of Philosophy, 2013)Model averaging is a technique used to account for model uncertainty in the process of multimodel inference. A frequentist model-averaged estimator is defined as a weighted average of the single-model estimates resulting ... -
(Thesis, Doctor of Philosophy, 2013)Baleen whales (mysticetes) form an essential part of modern ocean ecosystems, and show some of the most extreme adaptations evolved by any mammal. The evolutionary history of these animals has attracted much attention in ...
-
(Thesis, Master of Science, 2013)A common feature of mood disorders is disturbances of circadian rhythm and fluctuations in body weight. These are also common side effects of clinical anxiolytics. Likewise, those with eating disorders usually have comorbid ... -
(Thesis, Doctor of Philosophy, 2013)In streams and rivers draining agricultural catchments, deposited fine sediment and elevated nutrient concentrations represent two key land-use related stressors commonly associated with degraded ecological conditions that ... -
(Thesis, Doctor of Philosophy, 2013)We develop and apply meanfield methods to two systems of significant interest in cold atom physics. The first system, and the main subject of this thesis, is a gas of polarized dipoles, in which the particles have a long ... -
(Thesis, Master of Science, 2013)Longitudinal studies focusing on lifetime reproductive success (LRS) can be used to measure individual breeding performance, and identify commonalities amongst successful breeders. In some seabird species, it has been shown ...
-
(Thesis, Doctor of Philosophy, 2013)Epigenetic modifications to the genome, altering gene expression without changing the DNA sequence, can lead to changes to an individual’s phenotype. Furthermore, these changes to gene expression can be passed from one ...
-
(Thesis, Master of Science, 2013)Alzheimer’s disease (AD) is a neurodegenerative disorder that causes severe memory and cognitive decline and currently affects millions of people worldwide. Abnormal cleavage of the amyloid precursor protein (APP) has ...
-
(Thesis, Doctor of Philosophy, 2013)In 2007 the bottlenose dolphins of Doubtful Sound were reported to have been in decline for the previous 12 years. To identify and isolate potential causal factors, I began a comparative study of the resident populations ... -
(Thesis, Master of Science, 2013)Analysing dietary patterns is an alternative yet complementary approach to examining intakes of single nutrients, and can provide insight into relationships between the whole diet and risk of disease. Although several food ... -
(Thesis, Master of Science Communication, 2013)The aim of this thesis is to analyze the science of taxonomy, its development through time, and how effectively it is communicated to the non-scientific public. Taxonomy is the science of classification of organisms of any ... -
(Thesis, Doctor of Philosophy, 2013)Redundancy gain refers to the common finding in experimental psychology that the presentation of multiple, redundant stimuli tends to evoke responses more quickly and accurately when compared to presentation of a single ... -
(Thesis, Master of Science, 2013)The present research aimed to examine relations between parent reminiscing and later attachment. It was expected that parent reminiscing in early childhood be related to later attachment, even after accounting for continuities ...
