Summary
Linking movement and animal vision to uncover functions of dynamic colours. This project aims to address a fundamental biological question: what drives the extraordinary diversity of colours in nature? Using cutting-edge, interdisciplinary techniques, this project expects to link visual properties, movement and animal vision to discover functions of animal colouration, generating significant new insights for the fields of visual ecology, animal behaviour and camouflage. The outcomes of this proj ....Linking movement and animal vision to uncover functions of dynamic colours. This project aims to address a fundamental biological question: what drives the extraordinary diversity of colours in nature? Using cutting-edge, interdisciplinary techniques, this project expects to link visual properties, movement and animal vision to discover functions of animal colouration, generating significant new insights for the fields of visual ecology, animal behaviour and camouflage. The outcomes of this project include enhanced national and international collaboration and new tools for animal behaviour, perception and camouflage research. This work will benefit our understanding of vision, colour and the relationship between the two, with significant scope for bio-inspired solutions to sensor and image processing problems.Read moreRead less

Summary
The role of enemies in the generation of biodiversity. A fundamental question in biology is how new species are generated. The role of abiotic factors has been widely explored, but there is still little known about the role that ecological or behavioural interactions between organisms, such as parasitism or predation, play in the generation of diversity. This project aims to test the importance of anti-predator defences (warning colours) in generating species. It will combine micro- and macroevo ....The role of enemies in the generation of biodiversity. A fundamental question in biology is how new species are generated. The role of abiotic factors has been widely explored, but there is still little known about the role that ecological or behavioural interactions between organisms, such as parasitism or predation, play in the generation of diversity. This project aims to test the importance of anti-predator defences (warning colours) in generating species. It will combine micro- and macroevolutionary analyses to provide an in-depth test of this association. This project aims to provide a bridge between behavioural ecology and macroevolutionary processes, using Australian fauna, and increase our knowledge about whether and how enemies can contribute to generating diversity of life on earth.Read moreRead less
Escalating the arms race: Understanding when and how trees get really tall. Australia's giant Eucalypt trees are an amazing phenomenon and resource; underpinning unique ecosystems, rich in timber, stored carbon, and animal habitat. While tree height generally arises via an evolutionary arms race for light, the race has escalated dramatically in some locations and species. Using a computational framework that simulates adaptation driven by size-structured competition, this project will quantify h ....Escalating the arms race: Understanding when and how trees get really tall. Australia's giant Eucalypt trees are an amazing phenomenon and resource; underpinning unique ecosystems, rich in timber, stored carbon, and animal habitat. While tree height generally arises via an evolutionary arms race for light, the race has escalated dramatically in some locations and species. Using a computational framework that simulates adaptation driven by size-structured competition, this project will quantify how distinct factors-including climate, recruitment, and disturbance-enhance the race for light and can thereby explain the origins of Australia's giant Eucalypt. With calibrated models of species evolution, coupled with targeted fieldwork and big data, this project clarifies key forces shaping present and future vegetation.Read moreRead less
Macroecology of reptiles and frogs over latitudinal and temporal gradients. This project aims to address major macroecological concepts in reptile and frog communities through time, focusing on environmental and climatic gradients in species diversity and body-size variation. This project expects to generate a unique macroecological dataset by integrating data from Quaternary fossil sites spanning a 3000km latitudinal gradient with current ecological data. Expected outcomes include the first com ....Macroecology of reptiles and frogs over latitudinal and temporal gradients. This project aims to address major macroecological concepts in reptile and frog communities through time, focusing on environmental and climatic gradients in species diversity and body-size variation. This project expects to generate a unique macroecological dataset by integrating data from Quaternary fossil sites spanning a 3000km latitudinal gradient with current ecological data. Expected outcomes include the first comprehensive ecological assessment of Australian reptile and frog communities through Pleistocene climate oscillations, with predictions into the future. This research will benefit Australian society by providing evidence-based knowledge of faunal community composition through time in association with changing climates.Read moreRead less
Improving stream management using ecological modelling and DNA barcodes. Rivers and streams provide invaluable ecosystem services, yet are commonly degraded by human activities: a problem likely to be exacerbated by thermal and flow regimes being altered by climate change. Stream biodiversity is both a value and an indicator of ecological health: effective stream management requires prediction of biodiversity responses to natural environmental and human-impact gradients. By compiling a dataset o ....Improving stream management using ecological modelling and DNA barcodes. Rivers and streams provide invaluable ecosystem services, yet are commonly degraded by human activities: a problem likely to be exacerbated by thermal and flow regimes being altered by climate change. Stream biodiversity is both a value and an indicator of ecological health: effective stream management requires prediction of biodiversity responses to natural environmental and human-impact gradients. By compiling a dataset of macroinvertebrate species using new DNA metabarcoding, modelling their distributions, and ranking biodiversity by reach, we will develop molecular and quantitative spatial tools to provide data-driven, landscape-scale decision support for protecting and restoring streams: an urgent need for stream managers globally.Read moreRead less
