Freshwater Macroinvertebrate Responses to Multiple Stressors: Interactions Between Fine Sediment Grain Size and Flow Velocity Reduction
Agricultural development has resulted in the degradation of freshwater ecosystems worldwide. Disentangling the individual and combined effects of agricultural stressors is crucial for future land-use management and restoration ... -
Early exposure to atrazine in zebrafish: intergenerational effects and animal personality
Animal personality (consistent inter-individual differences in behaviour over time and context) is important for an individual’s fitness. Acute exposure studies in adults show that endocrine disrupting chemicals (EDCs) can ... -
Taipōrutu, Taonga Tuku Iho. Articulating a Mātauranga Māori ‘Sense of Place’.
Māori (the indigenous people of New Zealand) cultural values in relation to resource management within New Zealand, are often co-joined with a preservation framework. The practical implication of this, places identity as ... -
Marine Noise Pollution and Cetaceans: Making the Intangible Tangible through Participatory Sci-Art Exhibition
This thesis examines how to communicate the concept of marine noise pollution and its effect on cetaceans to the general public. Tackling a largely unknown and intangible subject, it investigates how to make these effects ... -
Communicating conservation with detection dogs
Public support and awareness is essential to effectively address conservation issues such as biodiversity decline in New Zealand. There is a need to develop approaches for enhancing public awareness and attracting new ... -
Taxonomy and genetic management of New Zealand's Leiopelma frogs
The taxonomic status of some of New Zealand’s endemic and threatened leiopelmatid frogs has been debated for years. I thus re-examined leiopelmatid diversity by studying the skeletal and external morphology of extinct and ... -
Foraging activity and colony thermoregulation of the honey bee Apis mellifera following exposure to the organophosphate pesticide chlorpyrifos
Honey bees (Apis mellifera L.) are important pollinators and yet, an increasing number of reports suggest honey bee populations worldwide are in decline. Pollinators face many environmental stressors, including exposure ... -
Linking science and management for effective long-term conservation: A case study of black-fronted terns/tarapirohe (Chlidonias albostriatus)
Conservation biologists are facing a huge challenge. Ongoing, human-induced global change is leading to accelerating biodiversity loss, particularly in freshwater ecosystems where many highly mobile and migratory species ... -
Population status and genetic diversity of the endemic black-billed gull Larus bulleri of New Zealand
The endangered black-billed gull (Larus bulleri) is endemic to New Zealand, and is the world’s most threatened gull species due to suspected large population declines. These gulls primarily rely on open gravel beds in ... -
Conservation Genetics of North Island Kōkako (Callaeas wilsoni)
Conservation genetics has recently been recognised as an important, although often overlooked, aspect of wildlife management. Applying molecular techniques and genetic concepts to management strategies has the potential ... -
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 ...
