The molecular mechanism of Xenopus regeneration and its activation in mammals
Reactive oxygen species (ROS) were recently identified as a requirement for successful tail regeneration in Xenopus larvae and are present throughout the process of tail regeneration. In this study, the link between ROS ...
Getting to the Heart of Stress Reactivity in Honeybees
Honey bee colony collapse disorder is a concerning phenomenon. It appears that the key to unlocking the factors driving CCD lies in understanding the honey bee stress response. Increased heart rate is a hallmark of acute ...
The genetic effects of bottlenecks and disease in three iconic New Zealand bird species
Studies exploring the genetic consequences of population bottlenecks are increasingly examining the loss of diversity at functional loci (such as genes associated with the immune system), while neutral markers (such as ...
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 ...
Environmental regulation of migratory movements by juvenile brown trout (Salmo trutta)
This thesis explores the role that environment and geographic landscape features have on migratory response in juvenile brown trout (Salmo trutta). Migratory strategy was found to be related to landscape features at the ...
Genetics and ecology of host specificity in the trematode parasite Maritrema novaezealandensis
The specialisation of organisms for their primary resources is a fundamental concept in evolutionary ecology. For parasites, resource specialisation is essentially equivalent to host specificity. Generalist parasites exploit ...
Reintroduction biology of tuatara (Sphenodon punctatus): identifying suitable founder animals and conservation translocation sites
The rate of biodiversity loss is not slowing despite global commitments. Conservation translocations, the intentional movement and release of organisms to restore populations, are an emerging tool to help reduce species ...
Applying a multidisciplinary framework for developing a shark bycatch reduction device
The overarching aim of this multidisciplinary thesis was to contribute to the development of a novel shark bycatch reduction device (BRD) that both meets fishing operators’ needs and is economically feasible. Following the ...
The effects of mating systems on parental care and male and female gametic investment in dunnocks
My thesis had the following aims. First, I quantified variation and maintenance of immune-associated toll-like receptor genes between an ancestral population of dunnocks from England and an introduced population of dunnocks ...
The lek breeding system of the Kākāpō (Strigops habroptilus): the role of vocalisations in female mate choice and kin clustering on leks
For a species to succeed, individuals must be able to attract a mate. The method in which they do this is known as a breeding system and it involves a diverse array of social behaviours. A lek breeding system is employed ...
