Impacts of climate change on sustainability of temperate native pasture: an experiment. The sustainable use of temperate native pastures is important economically because of grazing and for biodiversity since they are home to many threatened plants. Native pasture sustainability depends on maintaining species diversity and vegetation productivity. Climate change is likely to have major impacts on both factors. The aims of this project are to elucidate the impacts of climate change on the species ....Impacts of climate change on sustainability of temperate native pasture: an experiment. The sustainable use of temperate native pastures is important economically because of grazing and for biodiversity since they are home to many threatened plants. Native pasture sustainability depends on maintaining species diversity and vegetation productivity. Climate change is likely to have major impacts on both factors. The aims of this project are to elucidate the impacts of climate change on the species composition, productivity and nutritional quality of a grazed native pasture. This is important, as it will allow us to predict likely problems caused by global climate change and increase our understanding of the mechanisms underlying these changes.Read moreRead less
Ecology and conservation of a unique, threatened guanophilic invertebrate community. This project aims to study the biology and ecology of a unique assemblage of insects and other invertebrates that live specifically in bat guano at Naracoorte Caves World Heritage Area. The caves are a major ecotourism and research location because of their world famous Pliestocene fossils, and because one cave is a critical breeding site for the large bentwing bat, Miniopterus s. bassianii. The guano cave, whic ....Ecology and conservation of a unique, threatened guanophilic invertebrate community. This project aims to study the biology and ecology of a unique assemblage of insects and other invertebrates that live specifically in bat guano at Naracoorte Caves World Heritage Area. The caves are a major ecotourism and research location because of their world famous Pliestocene fossils, and because one cave is a critical breeding site for the large bentwing bat, Miniopterus s. bassianii. The guano cave, which contains numerous endemic invertebrates, is potentially threatened by both direct and indirect human impacts. The results of this research will form the basis of a long-term management strategy to conserve this diverse community.Read moreRead less
An inventory of past biodiversity in Western Australia using ancient DNA. Fossil bones and museum skins are genetic time capsules that facilitate the exploration of Australia's past biodiversity. Travelling back in 'genetic time' provides important insights into how ecosystems functioned prior to the arrival of Europeans and the feral species that accompanied them. This funding will facilitate research into the genetic heritage of endangered WA species such as Woylies and Cockatoos. Native speci ....An inventory of past biodiversity in Western Australia using ancient DNA. Fossil bones and museum skins are genetic time capsules that facilitate the exploration of Australia's past biodiversity. Travelling back in 'genetic time' provides important insights into how ecosystems functioned prior to the arrival of Europeans and the feral species that accompanied them. This funding will facilitate research into the genetic heritage of endangered WA species such as Woylies and Cockatoos. Native species face increasing pressures from climate change and invasive species. Compiling a genetic inventory of WA's past biodiversity will assist in developing scientifically sound conservation management responses. Such approaches are critically important if this biodiversity hotspot is to be preserved for future generations.Read moreRead less
Ocean currents and genetic connectedness in a complex archipelago. To what extent are marine coastal communities ?open?, i.e. how often do the oceans carry larvae far from their point of spawning, and what influence does such ocean transport have on the spread of genetic information? These are some of the most fundamental questions of biological oceanography; the project will provide new answers by using an extremely detailed genetic data set from the Houtman Abrolhos Islands off Western Austra ....Ocean currents and genetic connectedness in a complex archipelago.

These are some of the most fundamental questions of biological oceanography; the project will provide new answers by using an extremely detailed genetic data set from the Houtman Abrolhos Islands off Western Australian together with an advanced numerical ocean model especially suited to that environment and developed in Australia.Read moreRead less
Discovery of the molecular mode of action of karrikins in plants. Karrikins are a newly-discovered family of naturally-occurring plant growth regulators that stimulate seed germination and seedling vigour. They were discovered in smoke and while they are centrally important in fire ecology they have far wider significance since species from non-fire-prone regions also respond to karrikins. Our research will discover how karrikins work at the molecular level in plant cells. Our discoveries will b ....Discovery of the molecular mode of action of karrikins in plants. Karrikins are a newly-discovered family of naturally-occurring plant growth regulators that stimulate seed germination and seedling vigour. They were discovered in smoke and while they are centrally important in fire ecology they have far wider significance since species from non-fire-prone regions also respond to karrikins. Our research will discover how karrikins work at the molecular level in plant cells. Our discoveries will be applied to improve growth of crop plants, to stimulate germination of weeds so that they can be eradicated, and in restoration ecology to revegetate degraded land such as minesites. Australia's world-leading position in this new important research area will be enhanced.Read moreRead less
Matching of gas exchanger structure and function with activity and environment in air-breathing fishes. This project will investigate the physiology and structure of Australian fishes that use gills and breathe air. It will measure the partitioning of oxygen and carbon dioxide exchange between the aquatic (gills) and aerial (lung, swim-bladder or mouth) respiratory organs, in relation to dissolved oxygen in the water and metabolic energy demands by the fish. Rates of gas exchange, biochemical ....Matching of gas exchanger structure and function with activity and environment in air-breathing fishes. This project will investigate the physiology and structure of Australian fishes that use gills and breathe air. It will measure the partitioning of oxygen and carbon dioxide exchange between the aquatic (gills) and aerial (lung, swim-bladder or mouth) respiratory organs, in relation to dissolved oxygen in the water and metabolic energy demands by the fish. Rates of gas exchange, biochemical characteristics of the blood, anatomy and physiology of the exchange organs, and respiratory/locomotory coupling will be measured in three selected species during graded exercise. The results will help us understand the factors influencing the evolution of air-breathing.Read moreRead less
Differential expression and functional analysis of genes controlling metamorphosis and early neurogenesis of a model lower animal, the coral Acropora. This study will analyse, at a molecular level, the response of coral larvae to stimuli inducing settlement from the plankton and the process of establishment of a sessile, calcified colony. The knowledge gained will facilitate induction of settlement on demand in the most effective way.

This study will analyse, at a molecular level, the response of coral larvae to stimuli inducing settlement from the plankton and the process of establishment of a sessile, calcified colony. The knowledge gained will facilitate induction of settlement on demand in the most effective way. We will characterise known candidate genes which may be involved in settlement, and reveal a more complete picture using subtractive hybridisation. Studies of the nervous system and the changes that it undergoes at metamorphosis will promote understanding of the control of metamorphosis, and insights into how more complex nervous systems may have evolved.Read moreRead less
The role of natural selection in macroevolution: a case study examining convergence of form and function in marine predator guilds. Darwin's theory of evolution natural selection is one of the most successful in the history of science and provides the framework for modern biology: however, areas of debate or uncertainty are often misinterpreted by non-scientists as indication of fundamental flaws in the theory. New 'hi-tech' tools provide the opportunity to re-examine these areas, and also to de ....The role of natural selection in macroevolution: a case study examining convergence of form and function in marine predator guilds. Darwin's theory of evolution natural selection is one of the most successful in the history of science and provides the framework for modern biology: however, areas of debate or uncertainty are often misinterpreted by non-scientists as indication of fundamental flaws in the theory. New 'hi-tech' tools provide the opportunity to re-examine these areas, and also to demonstrate the process of science to the public. The new tool is Computational Biomechanics, the future of studying biological form, and this project will further develop the leading role of Australian research in this technology which has applications for palaeontology, environmental management, medical science, and the next generation of engineering using 'biomaterials'.Read moreRead less
