Science communication in risk management at a high-incidence location for suicide
It has been suggested that the role of robust scientific evidence in quality policy development is essential, but can vary on the basis of policy type and setting. These hypotheses and others were explored in a unique local ... -
Effects of avian predation and habitat degradation on the population dynamics of the jewelled gecko (Naultinus Gemmeus) from the Every Scientific Reserve, Otago Peninsula, New Zealand
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 ... -
Ship rat density in urban Dunedin and the development of a non-invasive estimation method
In New Zealand ship rats (Rattus rattus) are one of the major threats to endemic fauna and flora. Rural ship rat populations have been implicated in the ongoing decline and extinction of many species of endemic wildlife. ... -
Parasite-mediated interspecific interactions in a community of crustaceans
Differential impacts of parasitism among sympatric species influence important interactions among hosts, both directly and indirectly, which can translate to impacts on communities and ecosystems. This thesis investigated ... -
Effects of land use on the diet and growth of freshwater crayfish Paranephrops zealandicus in some New Zealand streams
I investigated the relationship between landuse and the diet and growth of the fresh-water crayfish Paranephrops zealandicus in the Taieri River catchment, South Island, New Zealand. The thesis presents a detailed dietary ... -
Mainland and near-shore islet colonies of Sooty Shearwaters (Puffinus griseus) in Otago
INVESTIGATION OVERVIEW: Many mainland breeding colonies of Sooty Shearwaters are thought to have become extinct, although there is no concern for the abundant offshore island populations of these burrow-nesting seabirds. ... -
Observations on growth and age of Hyridella menziesi Gray (Mollusca : Bivalvia) in a freshwater tidal lake
The freshwater mussel offers considerable scope for study of the relationship between growth and life span. The combination of slow prolonged growth, low adult mortality and longevity are apparently unique in Invertebrate ... -
Population ecology of the freshwater crayfish Paranephrops zealandicus and its effect on the community structure of a lowland bush stream
My research describes aspects of the population ecology of the freshwater crayfish Paranephrops zealandicus, its influence on the community of a lowland bush stream in Otago, New Zealand, and the ecosystem consequences of ... -
Ecological energetics of feral house mice (Mus musculus) inhabiting coastal sand dunes
Feral house mice (Mus musculus) are well established throughout New Zealand. They are a potential pest species about which comparatively little is known, especially with respect to invertebrate populations where we might ... -
The physiology of lizards from arid regions in Central Otago.
The seasonal cycles in fat bodies, liver and gonads of Leiolopisma zelandica and Hoplodactylus pacificus have been established and the pattern of lipid storage and utilization in these organs, the tail and remaining carcass ... -
Studies on neothyris lenticularis (Deshayes).
Neothyris lenticularis (Deshayes), the only living representative of its genus, is a member of the Order Telotremata within the Sub-Class Pygocaulia. Its taxonomic position has been discussed by Thomson (1915). As a result ... -
Water temperature and food availability influence brown trout (Salmo trutta) and rainbow trout (Oncorhynchus mykiss) population dynamics in the Cardrona River: implications for flow regime management
Reduced surface discharge negatively influences freshwater fish populations. Under the current flow regime management, the lower Cardrona River has experienced annual low flow events over the summer months. This low flow ... -
Perspectives on gaps in communication with breast cancer patients in New Zealand
The world of breast cancer is pink, female-centric and aimed at an older, post-menopausal demographic. Whilst it is fitting that health campaigns be aimed at the majority of patients registering with the disease, these ... -
The role of social structure and kin associations in the mating system of the polygynous New Zealand sea lion (Phocarctos hookeri)
Mating structure describes the number of mates individuals of each sex are able to acquire, as well as the variance in reproductive success between individuals of the same sex. Such structure has important evolutionary ... -
To what extent are young people engaged with the Predator Free 2050 goal?
People have a significant role to play when it comes to predator control. The announcement of the Predator Free 2050 goal (PF2050), in June 2016, will require the engagement of thousands of people across New Zealand. Given ... -
Biological functions of gonadotropic hormones during the early stages of ovarian development in shortfinned eel (Anguilla australis)
In teleosts, gonadotropins (Fsh: follicle-stimulating hormone and Lh: luteinizing hormone) secreted from the pituitary are key factors regulating gonadal steroid production and gametogenesis. At present, acquired insights ... -
Resource selection by New Zealand pāteke/brown teal (Anas chlorotis) at two North Island locations
Identification of the resources an animal is selecting allows us to understand how animals use what is available to meet their requirements for survival, growth, and reproduction. Understanding the process by which selections ... -
Trophic links and the parasites that exploit them: the case of New Zealand's endemic rough skate
Understanding how natural systems are structured and function is central to ecological theory. Although easily overlooked, parasites are ubiquitous and fundamental components of natural systems. Among their various roles, ... -
Ecology, genetics and taxonomy of Peka peka (Chiroptera: Mystacina tuberculata and Chalinolobus tuberculatus)
New Zealand has two species of microbat; the Short-tailed Bat (Mystacina tuberculata) and the Long-tailed Bat (Chalinolobus tuberculatus). Despite having special significance as being New Zealand's only native terrestrial ... -
Factors Influencing Varroa Sensitive Hygiene in European Honey Bees (Apis mellifera)
European honey bees (Apis mellifera) pollinate approximately one third of the world’s fruits and crops. The current loss of honey bee colonies is thus a major threat to the agricultural industry, to food production and to ...
