A shipload of consequences: studying the impact of Old World diseases on native South American populations via ancient DNA. This pioneering project will give the first real-time picture of the genetic changes induced by epidemics in human populations. This will reveal important new information about the likely impact of future epidemics on the genetic diversity of the immune system in modern human populations and will be of substantial use in building epidemiological models. By proposing to comb ....A shipload of consequences: studying the impact of Old World diseases on native South American populations via ancient DNA. This pioneering project will give the first real-time picture of the genetic changes induced by epidemics in human populations. This will reveal important new information about the likely impact of future epidemics on the genetic diversity of the immune system in modern human populations and will be of substantial use in building epidemiological models. By proposing to combine state-of-the-art science with global problems of humanity, we will address Australia's interests in expanding scientific expertise beyond its borders and place Australia at the leading edge of disease impact studies.Read moreRead less
Modes of speciation in subterranean diving beetles from calcrete aquifers of central Western Australia. Understanding speciation is a fundamental biological problem and our analyses of the diving beetles will broaden our understanding of modes of speciation and how an extraordinary biodiversity of subterranean animals (stygofauna) evolved in the limestone aquifers of central WA. The aquifers are an important source of water for pastoralists and mining companies and the limestone is also a valuab ....Modes of speciation in subterranean diving beetles from calcrete aquifers of central Western Australia. Understanding speciation is a fundamental biological problem and our analyses of the diving beetles will broaden our understanding of modes of speciation and how an extraordinary biodiversity of subterranean animals (stygofauna) evolved in the limestone aquifers of central WA. The aquifers are an important source of water for pastoralists and mining companies and the limestone is also a valuable resource, so there is a need for further research on the impacts of these uses. We will generate further knowledge of the diversity and biological significance of the stygofauna, information that is critical for the environmentally sustainable management of the aquifers and their ecosystems.

Development of Australian model systems for speciation research. Our project will contribute to an understanding of the process of speciation, a fundamental biological problem, for which there are few well-developed model systems in the world. We will further our understanding of how Australia's extraordinary diversity of animal species have evolved, knowledge which is valuable for understanding the future impact of climatic and environmental changes on species. Our research will generate furthe ....Development of Australian model systems for speciation research. Our project will contribute to an understanding of the process of speciation, a fundamental biological problem, for which there are few well-developed model systems in the world. We will further our understanding of how Australia's extraordinary diversity of animal species have evolved, knowledge which is valuable for understanding the future impact of climatic and environmental changes on species. Our research will generate further knowledge of the diversity and biological significance of subterranean fauna in the arid zone of Australia, providing important background data for assessing the impacts of mining activities on groundwater-dependent-ecosystems and improved strategies for their sustainable management.

Ecology, Physiology and Phylogeography: an integrated approach to the study of the invasive marine green macroalga Caulerpa taxifolia in Australia. The green marine macroalga Caulerpa taxifolia is one of the world's worst invasive species. In Australia 'exotic strains' of this alga are a listed pest species. Invasions in NSW and SA have caused environmental harm and managing them has cost $10 million since 2000. We propose to integrate ecology, physiology and genetic analyses to provide data to ....Ecology, Physiology and Phylogeography: an integrated approach to the study of the invasive marine green macroalga Caulerpa taxifolia in Australia. The green marine macroalga Caulerpa taxifolia is one of the world's worst invasive species. In Australia 'exotic strains' of this alga are a listed pest species. Invasions in NSW and SA have caused environmental harm and managing them has cost $10 million since 2000. We propose to integrate ecology, physiology and genetic analyses to provide data to better respond to this pest, potentially savings millions of dollars per year. We will produce the first empirical evidence of the effects of climate change and ocean acidification on this marine pest, in the context of increasing coastal human populations.Read moreRead less
