Simulating viral evolution and genetic complexity. This project has direct relevance to understanding the growth of viral infections, and therefore has possible practical applications in disease research and control. Examples of these are emerging diseases in humans such as those caused by HIV-1, SARS coronavirus and Dengue virus, which cause considerable human suffering throughout the world. A major part of current research into these diseases involves attempts to model the evolutionary geneti ....Simulating viral evolution and genetic complexity. This project has direct relevance to understanding the growth of viral infections, and therefore has possible practical applications in disease research and control. Examples of these are emerging diseases in humans such as those caused by HIV-1, SARS coronavirus and Dengue virus, which cause considerable human suffering throughout the world. A major part of current research into these diseases involves attempts to model the evolutionary genetics and dynamics of virus populations in order to understand how to control epidemics, develop vaccines and design drugs. The research program is designed to provide new computational modelling tools for this purpose, which may have wider applications as well.

This project aims to improve farm resilience, farm management, and economic decision-making in Australia and internationally. It expects to generate new interdisciplinary knowledge to integrate our understanding of agro-ecosystems and innovative tools to assess their status and manage their operations more effectively. Expected outcomes include the ability to inform farmers, bankers, and land managers about the trade-offs between resilience and efficiency on farms. This should provide significant benefits, including the ability to minimize financial risks to farmers and banks, allow better investment decisions, and achieve sustainable long-term outcomes for both private and public well-being.Read moreRead less

How does temperature affect complex life histories? A Cost Theory approach. This proposal seeks to understand how temperature affects the relative costs of early life history stages, from
development, through to energy independence for a diverse array of taxa, from seaweeds, to plants to
vertebrates. The proposed research seeks to test the predictions of a new framework, Developmental Cost
Theory, and extend this theory to include germination (for plants) and metamorphosis for animals. The antic ....How does temperature affect complex life histories? A Cost Theory approach. This proposal seeks to understand how temperature affects the relative costs of early life history stages, from
development, through to energy independence for a diverse array of taxa, from seaweeds, to plants to
vertebrates. The proposed research seeks to test the predictions of a new framework, Developmental Cost
Theory, and extend this theory to include germination (for plants) and metamorphosis for animals. The anticipated
goals are to provide clear predictions regarding which species are likely to thrive or suffer under continued global
warming, and a valuable framework for understanding how temperature shapes the life histories of organisms,
including those that are important from an ecological or agricultural perspective.Read moreRead less

Summary
Interactions of sexual selection & ecological divergence during speciation. Understanding the processes driving speciation is fundamental to understanding how biodiversity is generated. The two main forces underlying speciation, ecological divergence and sexual selection, are well characterised, yet how they interact during the speciation process is remarkably poorly understood. This project aims to test hypotheses regarding how ecological divergence and sexual selection interact during speciati ....Interactions of sexual selection & ecological divergence during speciation. Understanding the processes driving speciation is fundamental to understanding how biodiversity is generated. The two main forces underlying speciation, ecological divergence and sexual selection, are well characterised, yet how they interact during the speciation process is remarkably poorly understood. This project aims to test hypotheses regarding how ecological divergence and sexual selection interact during speciation, from its inception to its completion. In doing so, this research aims to identify genomic regions underlying divergence in colour patterns, which are important for ecological and sexual interactions. Consequently, this project will significantly enhance our understanding of ecological and genetic mechanisms underlying speciation.Read moreRead less
The role of leaf veins in vascular plant evolution. Leaves are continuously irrigated by a system of internal plumbing that defines their maximum photosynthetic output, and angiosperms are the most productive plants on earth largely by virtue of a uniquely efficient system of leaf plumbing. This project will identify how such an important modification of leaf water transport came to evolve.
Silicon: a novel solution to reduce water use and pest damage in wheat. The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si a ....Silicon: a novel solution to reduce water use and pest damage in wheat. The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si alleviates stress in wheat, from gene to farm scale, providing cost-benefit analysis and a best–practice toolbox for implementation by farmers. Outcomes are anticipated to provide a cheaper and more environmentally sustainable solution to issues of water scarcity and yield losses to pests in Australia’s leading crop.Read moreRead less
Early-life climate sensitivity: direct and indirect mechanisms. This project aims to investigate how climate change threatens animal populations by determining the mechanisms causing DNA damage (short telomeres) in nestling birds growing up in hot conditions. Telomeres are biomarkers of individual life expectancy, and short telomeres in young birds predict a decline in future population viability. Our project aims to determine the importance for heat-induced telomere shortening of: (1) nestling ....Early-life climate sensitivity: direct and indirect mechanisms. This project aims to investigate how climate change threatens animal populations by determining the mechanisms causing DNA damage (short telomeres) in nestling birds growing up in hot conditions. Telomeres are biomarkers of individual life expectancy, and short telomeres in young birds predict a decline in future population viability. Our project aims to determine the importance for heat-induced telomere shortening of: (1) nestling heat stress responses; (2) inheritance of heat-shortened sperm telomeres; and (3) parental buffering of heat effects. Expected benefits include enhanced reliability of climate change predictions and improved ability to identify climate change mitigation strategies before population declines are evident.Read moreRead less

This project aims to investigate the impact of global environmental change on the survival of Australia’s oyster industry, by combining the science of genetics, physiology and ecology to identify already resilient oysters. Through the first complete understanding of resilience in oysters, including the trade-offs they have made in other fitness traits, the project develops new capacities to 'climate and future-proof' our natural oyster populations and the Australian oyster industry, to enable the restoration of degraded oyster habitats. This project will ensure the future of an iconic and economically important national industry and food source and contribute to preserving the critical cultural links of Indigenous Australians with their lands.Read moreRead less
