Retroviruses in the common brush-tailed possum (Trichosurus vulpecula)
… in a marsupial, the common brush-tailed possum (Trichosurus vulpecula). Initial efforts were directed at detecting exogenous retroviruses in possums, but the majority of the work described in this thesis involved the isolation and characterisation of a possum endogenous retrovirus. Endogenous …

Food preferences and demand in the brushtail possum (Trichosurus vulpecula)
The common brushtail possum (Trichosurus vulpecula) has been reported to eat vegetation, fruit, invertebrates, and occasionally fungi, eggs and meat in the wild. The relative preference between food types found in the wild, however, has not been investigated in a controlled laboratory study. In …

Regulation of LH in the female common brushtail possum (Trichosurus vulpecula)
… investigated in the common brushtail possum (Trichosurus vulpecula). This research aimed to characterise the control of pulsatile LH release and the seasonal change of LH in response to oestradiol in the possum through the development of two main hypotheses. The first hypothesis proposed that …

Possum (Trichosurus vulpecula) responses and preferences to novel objects in their environment
The Australian brushtail possum (Trichosurus vulpecula Kerr 1792) is a major conservation and agricultural pest in New Zealand, and is currently a focus of much research to improve control efficacy. Traps and toxins stored within bait stations are used to control possums in ground-based operations, …

Possum magic : exploring colour vision in the common brushtail possum (Trichosurus vulpecula)
… colour vision in the Common Brushtail Possum (Trichosurus vulpecula). I firstly present a detailed analysis of the spectral transmission of light through the ocular media. Here, I demonstrated the variability of ocular media for three marsupial species: the ultraviolet light sensitive …

Life history variation and reproductive success in the common brushtail possum, Trichosurus vulpecula
… arboreal marsupial, the common brushtail possum (Trichosurus vulpecula). A population of T. vulpecula was studied from 2001-2004 on Magnetic Island, north Queensland; the population was censused each month by live-trapping. Demographic changes in the population were modelled using …

Interhemispheric transfer in a marsupial : a behavioural investigation of interhemispheric transfer of visual information in Trichosurus vulpecula
Eight marsupial phalangers, (Trichosurus vulpecula) with mid-saggital section of the optic chiasma were trained monocularly in a visual discrimination task, as were four which had, in addition, mid-saggital sections of the anterior commissure, fasciculus aberrans and hippocampal commissure. All …

Assessment of Seedling Recruitment Under Manuka (Leptospermum scoparium) and Kanuka (Kunzea ericoides) Plantings at Shakespear and Wenderholm Regional Parks
… impact of browsing on seedling recruitment by Trichosurus vulpecula, Oryctolagus cuniculus and Rattus rattus on seedlings under Leptospermum scoparium and Kunzea ericoides plantings in two Auckland Regional Council Parks (ARC), Shakespear and Wenderholm. The number of woody seedlings that …

Visualising continuous intra-landscape isolation for brushtail possums using least-cost modelling
… isolation for the brushtail possum (Trichosurus vulpecula), which is a notorious invasive species in New Zealand. Radio-telemetry and landscape genetics data were used to determine the appropriate scale of analysis, and to quantify the effect of landscape features on possum dispersal. …

Mammalian limb morphology: the role of the crawl in determining marsupial limb integration, development, and evolution
… (Monodelphis domestica, Sminthopsis macroura, Trichosurus vulpecula) and one eutherian (M. musculus). A reflex scope was used to place four points on the stylopod, zeugopod, and autopod and these points were used to determine gross length and width for each element. A combination of correlation …

Concurrent schedule performance of possums: a comparison of two models
… examined the behaviour of brushtail possums (Trichosurus vulpecula) under concurrent variable-interval schedules of reinforcement. In the first experiment the lever pressing of six possums resulted in intermittent access to a barley/carob mixture under four pairs of variable-interval …

Aspects of the ecology and management of small mammalian predators in northern New Zealand
… in Northland, New Zealand to target possums (Trichosurus vulpecula) and rodents (Rattus rattus, Rattus norvegicus & Mus musculus). All six feral cats (Felis catus), and the single stoat (Mustela erminea) and ferret (Mustela furo) being monitored at the beginning of the operation died of …

Phenology and frugivory of large-fruited species in northern New Zealand and the impacts of introduced mammals
… periods of egg development and nesting. Possum (Trichosurus vulpecula) and rodent (Rattus spp., Mus musculus) control was reflected in the number of possums and/or rodents caught in forest patches at the end of the study. Long-term pest mammal suppression resulted in no trappable possums, rats or …
