Comparative population structure of forest invertebrate species - habitat specific or species specific? Invertebrates that colonize decomposing logs are an important link in the food chain and major players in the recycling of forest debris. In addition, many threatened species occupy this habitat. Despite their undoubted economic and conservation significance, there is very little information on distribution, dispersal and population structure for any of these species. We will use genetic tool ....Comparative population structure of forest invertebrate species - habitat specific or species specific? Invertebrates that colonize decomposing logs are an important link in the food chain and major players in the recycling of forest debris. In addition, many threatened species occupy this habitat. Despite their undoubted economic and conservation significance, there is very little information on distribution, dispersal and population structure for any of these species. We will use genetic tools to investigate these patterns, and to determine whether they are specific to particular species, or the product of the habitat itself. Our results will indicate whether forest management strategies should focus on the preservation of individual species or their habitat.Read moreRead less

The proposed research program will focus on the preparation, characterisation and application of novel, small (nanometer size) particles and thin (micrometer thick)films derived from such particles. These new and advanced materials will be prepared by usinf a recently developed, highly versatile and facile technology to coat particles in solution. The strategy to be used entails the step-by-step construction of well-defined layers of different composition on particles and flat surfaces, thereby allowing unprecendented control over the material properties and function. This will provide new avenues for the application of nanoscale materials in biotechnology and nanotechnology.Read moreRead less
Mobility of log-dependent invertebrates in fragmented forest. Clearing of Australian native forests continues apace. This leads to declines in total forest area and creates isolated remnants with depleted woody debris. Critical forest processes driven by invertebrates occur in this debris. Despite its major economic and conservation significance, there is little information on the impacts of habitat loss and alteration on organisms in decomposing logs. We will utilize recent advances in popu ....Mobility of log-dependent invertebrates in fragmented forest. Clearing of Australian native forests continues apace. This leads to declines in total forest area and creates isolated remnants with depleted woody debris. Critical forest processes driven by invertebrates occur in this debris. Despite its major economic and conservation significance, there is little information on the impacts of habitat loss and alteration on organisms in decomposing logs. We will utilize recent advances in population genetics to compare impacts on a suite of log-dependent invertebrates in an islands-of-bush-in-a-sea-of-pines model. This will facilitate improvements in conservation and sustainable management outcomes in forests.Read moreRead less
Genes to phenotype: Exploiting the marsupial model. This research will exploit one of Australia's finest natural resources, its marsupial fauna. The features of marsupial reproduction and development provide a unique opportunity to answer fundamental biological questions. This research will show how the minor differences in key developmental genes that have arisen in their 100 million year isolation give rise to the characteristic differences in developmental timing and reproduction between mar ....Genes to phenotype: Exploiting the marsupial model. This research will exploit one of Australia's finest natural resources, its marsupial fauna. The features of marsupial reproduction and development provide a unique opportunity to answer fundamental biological questions. This research will show how the minor differences in key developmental genes that have arisen in their 100 million year isolation give rise to the characteristic differences in developmental timing and reproduction between marsupials and other mammals. The focus on reproduction and development will also provide invaluable knowledge to underpin efforts to conserve our endangered species and to control those that are overabundant.Read moreRead less
Re-uniting marsupials and eutherians by embryonic micromanipulation. The unique responsibility for transmitting life from generation to generation normally depends on the gametes. This project will use new reproductive technologies to investigate the properties of the oocyte in reprogramming somatic cell nuclei, and will use the nuclei of both marsupial and eutherian somatic cells to test this. We will also use both marsupial and eutherian genes to insert into the oocyte to create the first tra ....Re-uniting marsupials and eutherians by embryonic micromanipulation.

This project will use new reproductive technologies to investigate the properties of the oocyte in reprogramming somatic cell nuclei, and will use the nuclei of both marsupial and eutherian somatic cells to test this. We will also use both marsupial and eutherian genes to insert into the oocyte to create the first transgenic marsupials. We will also investigate the ability of spermatozoa from species of increasing genetic distance to ferttilise marsupial eggs using intracytoplasmic sperm injection (ICSI).Read moreRead less

The success and rapid evolution of invasive species: resolving a genetic paradox. Invasive species have an enormous economic impact on trade, agriculture, aquaculture, fisheries and eco-tourism in Australia. In order to negate such detrimental impacts, integrated strategies need to be formulated to effectively control and eradicate introduced species. Our limited knowledge of the factors underlying the success of invasive species has hampered such efforts.

Invasive species have an enormous economic impact on trade, agriculture, aquaculture, fisheries and eco-tourism in Australia. In order to negate such detrimental impacts, integrated strategies need to be formulated to effectively control and eradicate introduced species. Our limited knowledge of the factors underlying the success of invasive species has hampered such efforts. A detailed understanding of the invasion dynamics of introduced species is essential for identifying potential weaknesses that can be exploited in management strategies. My research will examine the invasion dynamics of a successful invasive species, the delicate skink, providing information directly relevant to the management of introduced species in Australia.Read moreRead less

The outcomes of this project will have immense benefit to Australia. They impact upon two areas of national importance, namely ensuring an environmentally sustainable Australia, and safeguarding Australia. In particular, the project will provide models, methodology and optimal strategies for sustainable use of Australia's biodiversity, for protecting Australia from invasive diseases and pests, and for protecting Australia from terrorism and crime. Special focus will be given to the control of invasive species, the control of emerging infections, and the optimal allocation of resources. The current risks posed by invasive diseases and pests, and the alarming rate of destruction of biodiversity, warrant urgent funding of this project.Read moreRead less
Reconstructing landscapes for biodiversity: From predictive modelling to future scenarios. Many landscapes around the world have been effectively denuded of natural vegetation, causing precipitous declines in native biodiversity.

Many landscapes around the world have been effectively denuded of natural vegetation, causing precipitous declines in native biodiversity. Mitigation of such effects in the near/medium-term future requires substantial ecological advice. We will employ our skills developed in modelling distributions of species across landscapes based on terrain, soils and climate to assess alternative landscape-reconstruction scenarios. This links use of existing data sets for initial modelling, a validation phase for testing model reliability and for refining models, and a subsequent GIS-based modelling phase in which alternative options for reconstructing landscapes are evaluated for their effectiveness in sustaining landscape-scale native biodiversity.Read moreRead less
