(Thesis, Master of Science, 1989)The breeding biology of the Rock Wren, Xenicus gilviventris, was studied in the Murchison Mountains, Fiordland during the 1983-84 and 1984-85 breeding seasons, observations generally being made of banded birds. Rock ...

Movement behaviour and habitat use of domestic cats in relation to threatened native lizard habitat (Thesis, Master of Science, 2008)While it is widely accepted that introduced mammals are responsible for the declines and extinctions of many native New Zealand fauna, less attention has been paid to the domesticated versions of those species, including ...
-
(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, Master of Science, 2000)Fire is an important perturbation in many ecosystems including wetlands. Fire ecology studies of bog wetlands in New Zealand have focussed on the recovery of post-fire vegetation. Other components of the ecosystem have ...
-
(Thesis, Master of Science, 2006)Movement is one of the most important behaviours exhibited by an animal and can have a great deal of impact on an individual's success. lt is also an important factor to consider in the conservation management of a species. ...
-
(Thesis, Doctor of Philosophy, 2013)The present study aimed to improve the reproduction success of captive hapuku by establishing methods for sex identification of broodstock (Chapter 2), by identifying predictors of egg quality at the time of spawning ...
-
(Thesis, Master of Science, 1986)Populations of Pyura pachydermatina at three different locations in Otago Harbour; Fryatt Street Wharf, Aquarium Point and Quarantine Island were studied and compared over a thirteen month period. At Fryatt Street Wharf ...
-
(Thesis, Master of Science, 2007)The yellow-eyed penguin (Megadyptes antipodes), or hoiho, is an endemic and endangered species of conservation importance in New Zealand. A primary management strategy for the conservation of the hoiho population along its ...
-
(Thesis, Doctor of Philosophy, 2006)A gene is imprinted when its expression is dependent on the sex of the parent from which it was inherited. An increasing number of studies are suggesting that imprinted genes have a major influence on medically, agriculturally ...
-
(Thesis, Master of Science Communication, 2013)Coffee was supposedly discovered by goats, and subsequently thrown into a fire, because religious monks deemed its stimulatory properties evil. However, instead of being destroyed, it turned brown and armoatic and became ...
-
(Thesis, Master of Science, 2013)In all organisms, fitness is maximised by trade-offs between life-history traits. It is commonly recognised that inter-specifically, relationships between life-history traits are often negative. Yet, when such relationships ...
-
(Thesis, Master of Science, 2013)The pelagic nudibranch Fiona pinnata (Mollusca: Gastropoda) occurs exclusively on macroalgal rafts and other floating substrata, and is found throughout tropical and temperate seas worldwide. Its cosmopolitan distribution ... -
(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 ... -
(Dissertation, Bachelor of Science with Honours, 1998)The aim of this study was to determine whether mating behaviour varies with head size in the alpine weta, Hemideina maori, from the Rock and Pillar range. The specific objectives are to : 1) determine the relative proportion ...
-
(Dissertation, Postgraduate Diploma in Wildlife Management, 1999)General introduction: Conservation of biodiversity is one the most important contemporary global problems faced by humanity. Human activity has caused the extinction of more than a thousand vertebrate species over the ...
-
(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)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 ...
-
Effects of dicyandiamide, a nitrification inhibitor, on nitrogen dynamics in freshwater environments (Thesis, Master of Science, 2009)In recent years, there has been growing concern that intensive fertilizer use has resulted in excessive nitrogen loading and pollution of surface waters in New Zealand. Dicyandiamide (DCD), a nitrification inhibitor, has ...
-
(Thesis, Master of Science, 2001)This study examined population dynamics of jewelled geckos at the Eve1y Scientific Reserve (ESR), Otago Peninsula, New Zealand. Research was conducted between November 1998 and December 1999. Based on mark-recapture I ...
-
(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 ...
