Summary
Genes and Environment in Development. Interactions between the early environment and the genetic regulatory program of the early embryo have major consequences for the development of individuals. The aim of this Network is to harness the resources of leading researchers from the previously distinct disciplines of developmental biology and developmental physiology to better understand developmental regulatory networks and how environmental factors impinge on them. The formation of such a Network ....Genes and Environment in Development. Interactions between the early environment and the genetic regulatory program of the early embryo have major consequences for the development of individuals. The aim of this Network is to harness the resources of leading researchers from the previously distinct disciplines of developmental biology and developmental physiology to better understand developmental regulatory networks and how environmental factors impinge on them. The formation of such a Network is unique, timely and strategic in that it will generate new insights into the mechanisms by which events in early life determine the risk of adverse outcomes in perinatal and adult life.Read moreRead less

This cross-disciplinary research will provide thorough understanding of the reproductive physiology of animals with different forms of reproduction, information critical for conservation and management of Australia's biodiversity. Australia's unique reptiles provide the best animal system in the world for research in this area. Our research on maternal-embryonic interactions in this animal model has direct implications for understanding some medical disorders, such as human angiogenic disorders. The research will strengthen ties internationally through research in South Africa, and provide training in combined biological and medical technologies. It will maintain Australia's long-term leadership in this area of research.Read moreRead less
Competition between regulatory processes in Amphibians: Testing the effects of physical and physiological factors on thermoregulation and hydroregulation. Regulation of body temperature is important for many animals, and it influences processes such as growth and reproduction. However, it is not clear to what extent wet-skinned animals can control body temperature because of evaporation. Understanding this about frogs is crucial to understanding their habitat requirements and the effects of clim ....Competition between regulatory processes in Amphibians: Testing the effects of physical and physiological factors on thermoregulation and hydroregulation. Regulation of body temperature is important for many animals, and it influences processes such as growth and reproduction. However, it is not clear to what extent wet-skinned animals can control body temperature because of evaporation. Understanding this about frogs is crucial to understanding their habitat requirements and the effects of climate change, habitat modification, and the invasion of cane toads on their populations. Amphibians are in decline worldwide, and research into the basic ways that these animals interact with the physical environment is needed before effective management plans can be produced. The unique physiological characteristics of Australian frogs make this is the best place in the world to do this research.Read moreRead less
Do frogs hydroregulate? Regulation versus tolerance of thermal and hydric states. Amphibians are in decline in Australia and worldwide. Frogs are a middle link in terrestrial and aquatic food chains (as predators and prey) so are important for the sustainability of Australia's biodiversity and as indicators of environmental problems. Basic research about the ways Australian frogs interact with the physical environment to balance body water and temperature is crucial to predicting the effects of ....Do frogs hydroregulate? Regulation versus tolerance of thermal and hydric states. Amphibians are in decline in Australia and worldwide. Frogs are a middle link in terrestrial and aquatic food chains (as predators and prey) so are important for the sustainability of Australia's biodiversity and as indicators of environmental problems. Basic research about the ways Australian frogs interact with the physical environment to balance body water and temperature is crucial to predicting the effects of climate change or habitat modification on frogs. This basic information is needed to produce effective conservation plans for native frogs and management plans for invasive cane toads. We will train students in techniques and concepts in ecology, conservation biology, and animal physiology.Read moreRead less
Predicting the Impact of Damming on the Endangered Mary River Turtle. Little is known about the effects of inland river alteration on the ecology of freshwater turtles, where river damming results in dramatic changes in river physical, chemical and biological characteristics. In Australia there are 446 large dams, necessary for hydro-electric power, navigation, flood control, irrigation and drinking water. Many of these rivers are inhabited by freshwater turtles, endemic to Australia, and this ....Predicting the Impact of Damming on the Endangered Mary River Turtle. Little is known about the effects of inland river alteration on the ecology of freshwater turtles, where river damming results in dramatic changes in river physical, chemical and biological characteristics. In Australia there are 446 large dams, necessary for hydro-electric power, navigation, flood control, irrigation and drinking water. Many of these rivers are inhabited by freshwater turtles, endemic to Australia, and this project will assess the impact of changes in habitat quality on the endangered Mary River Turtle (Elusor macrurus). The study comes at a timely opportunity, as proposed river damming will substantially alter the turtles' habitat, and its survival potential remains unknown.Read moreRead less
Food supply, diet and membrane lipids and the determination of metabolic rate. There are two types of polyunsaturated fatty acids (omega-3 and omega-6), which are both essential in the diet. This project will examine whether our current diet has a good balance of these two classes of fatty acids. It will examine the hypothesis that we do not have enough omega-3 polyunsaturates in our modern diet and that this imbalance has important consequences for metabolism and health. It will give insight in ....Food supply, diet and membrane lipids and the determination of metabolic rate. There are two types of polyunsaturated fatty acids (omega-3 and omega-6), which are both essential in the diet. This project will examine whether our current diet has a good balance of these two classes of fatty acids. It will examine the hypothesis that we do not have enough omega-3 polyunsaturates in our modern diet and that this imbalance has important consequences for metabolism and health. It will give insight into a relatively unappreciated cause of the current obesity epidemic and likely result in new strategies to combat this problem. It will have implications for other important health issues (such as depression) as well as for the food supply of Australia. Read moreRead less
Calcium regulation in the skeletal muscle triad and along the fibre. The fundamental role of skeletal muscle is posture and movement. Alterations in the normal way calcium regulates skeletal muscle function in fatigue, age and disease states causes loss of normal function. Preventing or controlling these changes is a key therapeutic aim. However, we currently lack full understanding of key mechanisms of calcium regulation in healthy skeletal muscle. This project will define key aspects of cal ....Calcium regulation in the skeletal muscle triad and along the fibre. The fundamental role of skeletal muscle is posture and movement. Alterations in the normal way calcium regulates skeletal muscle function in fatigue, age and disease states causes loss of normal function. Preventing or controlling these changes is a key therapeutic aim. However, we currently lack full understanding of key mechanisms of calcium regulation in healthy skeletal muscle. This project will define key aspects of calcium regulation that could be crucial to developing targets for improving function of skeletal muscle under stressed states.Read moreRead less
