Moving between day and night: Navigational strategies and foraging costs of temporal niche partitioning. This study involves fundamental research to identify the navigational strategies and the foraging cost in animals that occupy different temporal niches. It will make use of the unique research opportunities in Australia, by working with endemic fauna that allows scientists to address questions that would otherwise be hard to answer.

This study involves fundamental research to identify the navigational strategies and the foraging cost in animals that occupy different temporal niches. It will make use of the unique research opportunities in Australia, by working with endemic fauna that allows scientists to address questions that would otherwise be hard to answer. The project will introduce the novel technique of differential GPS to track the paths of ants which has the potential to revolutionise the field of insect navigation. Salience-dependent navigational strategies analysed in this study will be of great interest in the field of engineering and robotics.Read moreRead less
Moving to be seen: a comprehensive analysis of movement-based signal design. Papers on visual motion processing and animal signal design regularly feature in major journals, and the programs of international conferences. We can thus be confident that theoretical advances will attract international attention. We will develop further state-of-the-art methods in motion analysis, with our overall approach likely to serve as a framework for future research programs, although our techniques will have ....Moving to be seen: a comprehensive analysis of movement-based signal design. Papers on visual motion processing and animal signal design regularly feature in major journals, and the programs of international conferences. We can thus be confident that theoretical advances will attract international attention. We will develop further state-of-the-art methods in motion analysis, with our overall approach likely to serve as a framework for future research programs, although our techniques will have applications outside of biology. In addition, we will learn much about the social behaviour of a group of native reptiles about which relatively little is known. Research on the social behaviour of animals is readily comprehended by non-specialists and plays an important role in attracting young people to careers in science.Read moreRead less
Does size really matter? Selection, constraints and allometry. Australia is internationally recognized for its strong performance in evolutionary biology and quantitative genetics. This study contributes to the advancement of these fields. It is explicitly designed to create selection lines that can be used by developmental biologists, physiologists, geneticists and endocrinologists. This will strengthen links between institutes within Australia and internationally and later allow more applied q ....Does size really matter? Selection, constraints and allometry. Australia is internationally recognized for its strong performance in evolutionary biology and quantitative genetics. This study contributes to the advancement of these fields. It is explicitly designed to create selection lines that can be used by developmental biologists, physiologists, geneticists and endocrinologists. This will strengthen links between institutes within Australia and internationally and later allow more applied questions to be asked. Although this study addresses a basic research question, it uses techniques and statistics that are integral to work selecting for improvement of commercial crops and animals. It therefore provides valuable training opportunities for an essential part of Australia's agricultural sector.Read moreRead less
The origins, global spread and evolution of novel honey bee parasites. This project aims to study how emergent diseases arise, spread and evolve, studying varroa mites – a parasite of honey bees that will inevitably arrive in Australia and is expected to damage agriculture and the environment. As the mites have a well-characterised native range, independent host switches and a well-documented history of spread, they make good models. Mites have evolved after invasion, although without significan ....The origins, global spread and evolution of novel honey bee parasites. This project aims to study how emergent diseases arise, spread and evolve, studying varroa mites – a parasite of honey bees that will inevitably arrive in Australia and is expected to damage agriculture and the environment. As the mites have a well-characterised native range, independent host switches and a well-documented history of spread, they make good models. Mites have evolved after invasion, although without significant genetic differentiation at neutral markers. This project aims to identify genetic mechanisms associated with the host switches; reconstruct the pattern and demography of varroa’s global spread; and determine how selection acted on the mites after the host switch.Read moreRead less

The Evolution of stripe rust virulence. Fungal crop pathogen epidemics lead to severe yield losses worldwide, impact national economies and individual human lives. Wheat stripe rust fungal epidemics caused by new virulent races can lead to 80 per cent reduction in yield. This project aims to investigate the molecular mechanisms leading to newly virulent races by whole genome, epigenome and transcriptome comparison of several wheat stripe rust races. This project aims to fundamentally advance our ....The Evolution of stripe rust virulence. Fungal crop pathogen epidemics lead to severe yield losses worldwide, impact national economies and individual human lives. Wheat stripe rust fungal epidemics caused by new virulent races can lead to 80 per cent reduction in yield. This project aims to investigate the molecular mechanisms leading to newly virulent races by whole genome, epigenome and transcriptome comparison of several wheat stripe rust races. This project aims to fundamentally advance our understanding of evolutionary forces driving virulence and specification at the whole (epi-)genome level in important fungal crop pathogens. This will promote new crop protection strategies important for local and global food security in an ever-changing environment.Read moreRead less
The evolution of light detection and its impacts on early vertebrate evolution. The eye is a complex organ crucial for survival. Tracing the evolution of the eye will not only provide basic concepts of how building visual complexity is achieved in nature but also enhance the understanding of the selection pressures driving the radiation of early vertebrates.

Summary
Biological adaptation under natural and anthropogenic conditions. This project covers all four national priority areas. Nature abounds with conflicts between what is good for the individual or a larger entity (a population, a society, or a species). Researching them will explain why populations adapt or fail to adapt to novel conditions (e.g., climate change) and predict when interventions are beneficial. Similar rules govern the spread of invasive species. Even health problems, e.g., new virule ....Biological adaptation under natural and anthropogenic conditions. This project covers all four national priority areas. Nature abounds with conflicts between what is good for the individual or a larger entity (a population, a society, or a species). Researching them will explain why populations adapt or fail to adapt to novel conditions (e.g., climate change) and predict when interventions are beneficial. Similar rules govern the spread of invasive species. Even health problems, e.g., new virulent strains of human, animal or plant diseases, require such evolutionary thinking. Cutting-edge mathematical tools also prepare Australians for an era in the near future where genomic data are so cheap to acquire that training in complex mathematical and logical analysis becomes a factor limiting scientific progress.Read moreRead less
Evolution of Australia's globally unique hotspot of floral diversity. Australia has a globally recognised biodiversity hotspot, the southwest of Western Australia, but this unique eucalypt-dominated flora is threatened. This project will gain new insights into the evolutionary processes that generate and maintain such diversity, their vulnerability; and how the iconic eucalypts came to dominate the Australian landscape.
Climate change and cryptic biodiversity in the Australian arid-zone: Molecular phylogeny-based assessment of conservation priorities. Australia's arid zone comprises two thirds of the country yet from a climate change, biodiversity, and conservation point of view it has received little attention relative to eastern Australia.

Australia's arid zone comprises two thirds of the country yet from a climate change, biodiversity, and conservation point of view it has received little attention relative to eastern Australia. The project will address broad questions in evolutionary biology with unique Australian systems, make a world class contribution to the fields of phylogeography, molecular phylogenetics and conservation genetics and contribute substantially to the continued training of high quality research students and postdoctoral fellows. The project directly addresses two National Priority Research Areas and will supply of critical information to the eight biggest of the 57 Natural Resource Management Regions. Read moreRead less
