The role of neurohormones in the regulation of appetite and successful sea water transfer in farmed Atlantic salmon. Cultured Atlantic salmon spend the first part of their life in freshwater and then following a physiological adaption phase called smoltification, the fish (now termed smolts) are transferred to sea cages for growout. A proportion of smolts fail to thrive after transfer, show slow or no growth and usually die some months later. This project will investigate the role that the neuro ....The role of neurohormones in the regulation of appetite and successful sea water transfer in farmed Atlantic salmon. Cultured Atlantic salmon spend the first part of their life in freshwater and then following a physiological adaption phase called smoltification, the fish (now termed smolts) are transferred to sea cages for growout. A proportion of smolts fail to thrive after transfer, show slow or no growth and usually die some months later. This project will investigate the role that the neurohomones that control both appetite and physiological stress in fish have in stimulating the resumption of feeding after sea water transfer.The basic knowledge generated will be used directly in development of strategies for minimising smolt failure in Atlantic salmon aquaculture.Read moreRead less
The cellular basis of temperature impairment of reproductive function in Atlantic salmon. Elevated summer and autumn temperatures, either as a result of normal climate variation or global warming, inhibit reproduction in salmonid fishes by disrupting endocrine (hormonal processes). The mechanisms involved are unclear but are known to involve inhibition of ovarian estrogen and the assembly of egg-yolk proteins. This project will investigate the cellular basis of the inhibitory effect of high temp ....The cellular basis of temperature impairment of reproductive function in Atlantic salmon. Elevated summer and autumn temperatures, either as a result of normal climate variation or global warming, inhibit reproduction in salmonid fishes by disrupting endocrine (hormonal processes). The mechanisms involved are unclear but are known to involve inhibition of ovarian estrogen and the assembly of egg-yolk proteins. This project will investigate the cellular basis of the inhibitory effect of high temperature on reproduction, at the ovarian and hepatic levels. The understanding developed will be an essential component of amelioration strategies for managing the continued successful rearing of salmon and trout under warming environmental conditions.Read moreRead less
Critical windows: understanding changes in eating and physical activity over the transition from secondary school to young adulthood. This project will explain changes in eating, physical activity and sedentary behaviour during the critical period of transition from secondary school to young adulthood. It will provide important information on how we can assist adolescents to maintain a healthy lifestyle over a time characterised by several major life changes.
Vulnerability, autonomy and justice. Vulnerable people require assistance and care. But what are our responsibilities in relation to the vulnerable? And how can we provide assistance and care while avoiding stereotyping or paternalism? This research will advance ethical theory and be useful in solving practical problems in health research and policy.
Evolutionary, macroecological and phylogenetic patterns in Australasian freshwater crayfish. This project connects Australian systematists to a worldwide project that involves all of the world's living experts on freshwater crayfish evolution in a coordinated effort to answer some very important evolutionary questions. It involves a group of invertebrate animals that are not only readily recognisable, but which in Australia includes the world's largest and the world's most terrestrial crayfish s ....Evolutionary, macroecological and phylogenetic patterns in Australasian freshwater crayfish. This project connects Australian systematists to a worldwide project that involves all of the world's living experts on freshwater crayfish evolution in a coordinated effort to answer some very important evolutionary questions. It involves a group of invertebrate animals that are not only readily recognisable, but which in Australia includes the world's largest and the world's most terrestrial crayfish species. Information gained from the project will contribute to the management of crayfish biodiversity, identification of threatened species and tools to identify these prominent and important members of Australian freshwater ecosystems.Read moreRead less
The effects of maternal attachment, marital satisfaction and sensitivity to infants on infants attachment and adjustment: A longitudinal-structural equation study. This study will examine how family and attachment factors effect the adjustment of infant at 24 months of age. A longitudinal study, using structural equation method, will examine how maternal attachment and marital satisfaction when infants are 4 months of age will effect maternal parenting behaviors two months later, and how all thr ....The effects of maternal attachment, marital satisfaction and sensitivity to infants on infants attachment and adjustment: A longitudinal-structural equation study. This study will examine how family and attachment factors effect the adjustment of infant at 24 months of age. A longitudinal study, using structural equation method, will examine how maternal attachment and marital satisfaction when infants are 4 months of age will effect maternal parenting behaviors two months later, and how all three of these measures will effect infant attachment 6 months later. It will then examine how all four of these measures will effect the adjustment of infants 12 months later. The study will have important implications for early intervention and prevention of psychological problems in infants and children.Read moreRead less
Convicts and Diggers: a demography of life courses, families and generations. Based on convict records, birth, death and marriage registrations, World War One service records, and other historical data, this project explores long-term demographic outcomes of individuals, families and lineages. The project draws on the expertise of family historians to trace individuals and their descendants for 'Australia's biggest family history'.
Individual, social and physical environmental influences on children's active transport and independent mobility. Childhood obesity is likely to have significant economic and social impacts on Australian society. Preventing further increases in this disease is crucial, particularly among children at high risk such as those living in rural or disadvantaged areas. The promotion of behaviours such as active transport may have a significant benefit for public health; however little is known about wh ....Individual, social and physical environmental influences on children's active transport and independent mobility. Childhood obesity is likely to have significant economic and social impacts on Australian society. Preventing further increases in this disease is crucial, particularly among children at high risk such as those living in rural or disadvantaged areas. The promotion of behaviours such as active transport may have a significant benefit for public health; however little is known about what influences active transport among children in rural or disadvantaged areas. This study will identify important factors influencing active transport and will directly inform strategies aiming to promote health and wellbeing, thereby creating a healthier generation of Australian children.Read moreRead less
A novel regulator of growth signalling in Drosophila. This project aims to increase understanding of how growth is regulated by growth factor hormones. In animals, growth is controlled by signalling pathways that are activated by secreted peptide hormones. A new regulator of growth in the fruitfly Drosophila, the membrane attack complex/perforin-like (MACPF) protein Torso-like, has been identified. The project aims to unravel how Torso-like functions to regulate growth, thus throwing light on th ....A novel regulator of growth signalling in Drosophila. This project aims to increase understanding of how growth is regulated by growth factor hormones. In animals, growth is controlled by signalling pathways that are activated by secreted peptide hormones. A new regulator of growth in the fruitfly Drosophila, the membrane attack complex/perforin-like (MACPF) protein Torso-like, has been identified. The project aims to unravel how Torso-like functions to regulate growth, thus throwing light on the role this protein family may play in all animals. The findings are expected to provide key insights into the modification of growth factor activity, which is often dysregulated in human cancers and growth disorders, and may enable the design of new strategies for interfering with insect development for pest control.Read moreRead less
Info-chemicals for the environmentally sustainable management of autumn gum moth and scarab beetle pests of bluegum plantations. Insect pest control in Australian bluegum plantations currently relies on insecticides. Insecticides are incompatible with maintaining populations of native beneficial insects and achieving biotic regulation of pest populations.

Insect pest control in Australian bluegum plantations currently relies on insecticides. Insecticides are incompatible with maintaining populations of native beneficial insects and achieving biotic regulation of pest populations. Info-chemicals offer ways of disrupting pest populations that are benign to beneficials because they only interfere with the responses of the target insect. This project will pioneer the development of sex pheromone-based technologies for managing autumn gum moth and reveal potential applications of info-chemicals for managing scarab beetles. Application of info-chemical solutions to plantation pests will improve public perception of the industry and assist with forestry standard certification.Read moreRead less
