The origins of electroreception and nocturnality in the earliest known jawed vertebrates and their bearing on vertebrate diversification. This project aims to discover primary new data to pinpoint the timing, anatomical origins and phylogenetic significance when two key sensory systems first appeared in modern vertebrates: electroreception and specialised nocturnal vision.

This project aims to discover primary new data to pinpoint the timing, anatomical origins and phylogenetic significance when two key sensory systems first appeared in modern vertebrates: electroreception and specialised nocturnal vision. Such abilities today allow high diversity of vertebrates to co-exist within the same geographical range, for example on tropical reefs or rainforest communities, through careful temporal niche partitioning where reliance on other sensory systems takes over from vision and olfaction as the principal method of prey detection. This project aims to elucidate how the modern fish diversity was shaped by such significant early evolutionary events.Read moreRead less
Resolving evolutionary problems at the fish-tetrapod transition. The project aims to investigate very early Australian tetrapod trackways and conduct fieldwork to resolve the place of origin and timing of the evolution of the first tetrapods. The evolution of fishes to tetrapods was one of the key events in evolution. Studies on Northern Hemisphere fossils place an origin for the group around 380 million years ago. Australian fossils suggest a much older origin. New micro computed tomography dat ....Resolving evolutionary problems at the fish-tetrapod transition. The project aims to investigate very early Australian tetrapod trackways and conduct fieldwork to resolve the place of origin and timing of the evolution of the first tetrapods. The evolution of fishes to tetrapods was one of the key events in evolution. Studies on Northern Hemisphere fossils place an origin for the group around 380 million years ago. Australian fossils suggest a much older origin. New micro computed tomography data from Australian 3-D fossil fishes, combined with study of rare tetrapod gill arch bones, would enable us to determine the origins of tetrapod air-breathing and its ecological setting. The project may facilitate a rewriting of vertebrate evolution's most significant first step.Read moreRead less
Structural And Functional Analysis Of A Cancer-linked Co-regulator Complex

Summary
We seek to understand the mechanisms by which genes are switched on and off throughout our lifetime. A number of multi-component protein machines are involved in this process but their make-up and mechanism of action is not understood. We will investigate the structure and function of one of these machines that has been strongly linked to cancer.
REGULATION OF RYANODINE RECEPTOR CALCIUM CHANNELS BY THE CALCIUM BINDING PROTEIN CALSEQUESTRIN. The project is to examine the functional interaction between two proteins in skeletal muscle that are essential for Ca2+ regulation and hence contraction, respiration and movement in all vertebrate species. One protein, the ryanodine receptor, releases calcium from stores inside the muscle cell. The other protein, calsequestrin, binds and sequesters calcium ions. We have recently discovered that th ....REGULATION OF RYANODINE RECEPTOR CALCIUM CHANNELS BY THE CALCIUM BINDING PROTEIN CALSEQUESTRIN. The project is to examine the functional interaction between two proteins in skeletal muscle that are essential for Ca2+ regulation and hence contraction, respiration and movement in all vertebrate species. One protein, the ryanodine receptor, releases calcium from stores inside the muscle cell. The other protein, calsequestrin, binds and sequesters calcium ions. We have recently discovered that the proteins also bind to each other and that calsequestrin regulates Ca2+ release from the stores through the ryanodine receptor ion channel. This regulation is likely to be important in conserving store calcium during stress or fatigue.Read moreRead less
Nutritional ecology of free ranging herbivores. Australian grasslands underpin most of our livestock industries and provide important habitats for many native plants and animals. In order to manage these areas sustainably, farmers and other land managers need to know how much food animals consume and how the nutritional quality of that food varies. However there is no simple way of doing this and this prevents timely manipulation of stock numbers and limits our ability to predict fluctuations i ....Nutritional ecology of free ranging herbivores. Australian grasslands underpin most of our livestock industries and provide important habitats for many native plants and animals. In order to manage these areas sustainably, farmers and other land managers need to know how much food animals consume and how the nutritional quality of that food varies. However there is no simple way of doing this and this prevents timely manipulation of stock numbers and limits our ability to predict fluctuations in numbers of native herbivores such as kangaroos. The project will provide a cheap and quick means for ecologists and land managers to incorporate nutritional analyses into their work

The facility will be based at the University of New England and be used by animal scientists, molecular biologists, parasitologists, immunologists and botanists at these institutions, in many cases in collaborative research projects. It will also support the training of seven PhD students and a post-doctoral fellow. The facility will be unique to the region and will remove our current need to use facilities in Brisbane or Sydney.Read moreRead less
Development of Novel Pesticidal Agents. We have discovered a family of naturally occurring plant proteins called the cyclotides that have potent insecticidal activity against Helicoverpa species, one of the major pests on cotton and corn in Australia and world wide. Preliminary evidence has shown that they also have activity against major pests to livestock in Australia, including sheep blowflies. To develop these proteins as potential pesticidal agents it is necessary to understand the struct ....Development of Novel Pesticidal Agents. We have discovered a family of naturally occurring plant proteins called the cyclotides that have potent insecticidal activity against Helicoverpa species, one of the major pests on cotton and corn in Australia and world wide. Preliminary evidence has shown that they also have activity against major pests to livestock in Australia, including sheep blowflies. To develop these proteins as potential pesticidal agents it is necessary to understand the structural basis for their activity. We will do this by chemically synthesising peptides with selected residues mutated to determine their effects on activity.Read moreRead less

For 40 years, Burma has been controlled by a military dictatorship with human rights abuses occurring daily. Terror and political violence are used as tools of repression.

For 40 years, Burma has been controlled by a military dictatorship with human rights abuses occurring daily. Terror and political violence are used as tools of repression. An in-depth ethnographic study will be conducted into the relationship between emotional/psychological distress and the violence and fear that pervades everyday Burmese life. The project will test the hypothesis that religion plays an important role in mediating responses to fear. No other study has been conducted of everday life under this dictatorship, or of survival strategies created to alleviate fear. Outcomes will include refereed articles, a major monograph on the subject and the development of a new methodology appropriate for aiding victims of terror and torture.Read moreRead less
Manipulative mothers and family feuds: evolution of maternal effects under mother-offspring conflict. Can mothers shape the lives of their offspring and their grand-offspring? Can siblings shape the lives of their brothers and sisters? This project will address how mother and offspring strategies affect current and future generations. This is crucial for understanding how mothers will direct and accelerate evolutionary change in our changing world.
