This research will significantly advance understanding of how animals can respond to climate change, and the results will benefit wildlife management processes. The proposed research will lead to collaboration with Prof. Ken Storey an ISI highly cited author and expert in microarray analysis. The cDNA microarray for Crocodylus porosus which I will construct in the proposed research will be a valuable resource for Australia by increasing collaborations, and it will help find the cause of problems prevalent in the crocodile industry such as runt animals that significantly decrease production efficiency.Read moreRead less
Responses of reptiles to fluctuating thermal environments: behaviour or biochemistry? I propose a conceptual shift in the way thermal physiology of reptiles is interpreted, questioning the predominant role of behaviour in reptilian thermoregulation. I will test the hypothesis that changes in cellular biochemistry are an important mechanism by which reptiles respond to environmental fluctuations. I will determine the relationship between metabolic enzyme activity and performance functions, and ....Responses of reptiles to fluctuating thermal environments: behaviour or biochemistry? I propose a conceptual shift in the way thermal physiology of reptiles is interpreted, questioning the predominant role of behaviour in reptilian thermoregulation. I will test the hypothesis that changes in cellular biochemistry are an important mechanism by which reptiles respond to environmental fluctuations. I will determine the relationship between metabolic enzyme activity and performance functions, and the results may call for a re-assessment of current concepts such as the notion that reptiles must achieve "preferred" body temperatures to maintain performance.Read moreRead less
Cellular Gene Regulation Networks. The benefit to Australia will be scientific in terms of providing an understanding of how cells integrate transcriptional control systems and the networks that are involved. This will inform research on folate deficiency and aberrant human development and towards identifying genes that are important in improving efficiency of microbial fermentations. Additional and more practical major benefits will follow from the development of tools to analyse interaction ....Cellular Gene Regulation Networks. The benefit to Australia will be scientific in terms of providing an understanding of how cells integrate transcriptional control systems and the networks that are involved. This will inform research on folate deficiency and aberrant human development and towards identifying genes that are important in improving efficiency of microbial fermentations. Additional and more practical major benefits will follow from the development of tools to analyse interactions between control systems, including software of value to the research community. The work will provide postgraduate students with major training in up-to-date genomic technologies, and in the interface between application of bioinformatics and experimental science.

The study will provide critical information about the thermal and energetic capabilities and requirements of native Australian mammals. As little is known about the functional adaptations of arid zone mammals in the wild, these results will be a significant advancement in knowledge about the biology of native Australian species. The data will allow us to predict whether and how populations may be affected in the future and provide wildlife managers with an additional tool for making appropriate and sound decisions for the conservation of wildlife. Moreover, the project will enhance the scientific standing of Australia, improve international collaboration, and train students.Read moreRead less
Cool mammals: responding to thermal and energetic challenges in the Australian tropics. A detailed understanding of thermal biology and energy use of mammals is essential for predicting how they will respond to climate change. As little is known about the functional and behavioural traits of Australian tropical mammals, the proposed work investigating the thermal energetics and foraging biology of eleven native species will result in a significant advancement in knowledge. This information will ....Cool mammals: responding to thermal and energetic challenges in the Australian tropics.

As little is known about the functional and behavioural traits of Australian tropical mammals, the proposed work investigating the thermal energetics and foraging biology of eleven native species will result in a significant advancement in knowledge. This information will provide wildlife managers with an additional tool for making sound science-based decisions for the conservation of wildlife now and in the future. The project will train students, improve international collaboration, and substantially enhance the international scientific standing of Australia.Read moreRead less
Intra-genomic conflict and the evolution of sexually selected traits. The dynamics of sexual selection may prevent the simultaneous optimization of traits shared by the sexes, or of different traits within each sex. This proposal focuses on the consequences of these conflicts for phenotypic and genomic evolution. First, I will compare selection acting on a sexually dimorphic trait in males and females. Second, I will use artificial selection to create a novel sexually dimorphic trait, and track ....Intra-genomic conflict and the evolution of sexually selected traits. The dynamics of sexual selection may prevent the simultaneous optimization of traits shared by the sexes, or of different traits within each sex. This proposal focuses on the consequences of these conflicts for phenotypic and genomic evolution. First, I will compare selection acting on a sexually dimorphic trait in males and females. Second, I will use artificial selection to create a novel sexually dimorphic trait, and track the evolutionary response. Third, I will investigate the link between two important fitness traits: body size and ageing rate. This work will enhance important on-going research in the laboratory of Robert Brooks (UNSW).Read moreRead less
Additive and non-additive genetic benefits of mating behaviour: a synthesis of sexual selection and conservation genetics. This research will forge a synthesis between the study of mating behaviour and it's consequences (sexual selection) and the field of conservation genetics. It will have direct relevance to conservation attempts, and far-reaching implications for how we understand sexual behaviour and the complex mating decisions animals and humans make. The work will enhance Australia's stro ....Additive and non-additive genetic benefits of mating behaviour: a synthesis of sexual selection and conservation genetics.

Does testosterone produce duds or studs? A performance-based examination of the Immunocompetence Handicap Hypothesis. The evolutionary persistence of testosterone (T) as a vertebrate reproductive hormone is viewed as a double-edged sword. On the one hand T secretion is required for development and expression of appropriate reproductive functions. On the other hand T is known to suppress immune functions and is thus considered a liability to male health. We are examining an alternate hypothesis: ....Does testosterone produce duds or studs? A performance-based examination of the Immunocompetence Handicap Hypothesis. The evolutionary persistence of testosterone (T) as a vertebrate reproductive hormone is viewed as a double-edged sword. On the one hand T secretion is required for development and expression of appropriate reproductive functions. On the other hand T is known to suppress immune functions and is thus considered a liability to male health. We are examining an alternate hypothesis: that T-induced immunosuppression benefits breeding males by protecting their physical performance levels during immune challenge. We will examine this hypothesis by quantifying the interactive effects of T and immune challenge on the aerobic capacity of male birds.Read moreRead less
