The evolutionary biology of seminal fluid. This project will identify proteins within seminal fluid that impact sperm performance and male fertility. The work will derive new insights into the evolution of seminal fluid proteins, while simultaneously exploring how environmental factors such as diet impact male fertility in animals and humans.
Adaptive function of insect cuticular lipids. Insects secrete onto their surface a cocktail of high melting-point waxes. These biological compounds have been found to be involved in communication but are also thought to protect the insect from water loss and pathogen invasion. Insects represent the most abundant group of animals on Earth. It has been suggested that the dual role of surface waxes in ecological adaptation and reproduction may be key to their remarkable divergence. However, little ....Adaptive function of insect cuticular lipids. Insects secrete onto their surface a cocktail of high melting-point waxes. These biological compounds have been found to be involved in communication but are also thought to protect the insect from water loss and pathogen invasion. Insects represent the most abundant group of animals on Earth. It has been suggested that the dual role of surface waxes in ecological adaptation and reproduction may be key to their remarkable divergence. However, little is known of the function of individual compounds within mixtures of insect waxes. Using chemical analysis, neurophysiology and whole animal performance, the aim of this project is to provide a detailed understanding of the function of insect surface wax with potential for bioinspired products.Read moreRead less
The oxygen paradox and the evolution of sex differences. Free radicals are reactive molecules linked to the onset of ageing, cancers and infertility. By advancing an emerging paradigm that contends that 'free radicals' are important drivers of evolutionary change, this project will lead the field and provide an excellent platform on which to train students to the highest standards.

Summary
Understanding bioacoustics in plants. From lush tropical rainforests to small urban gardens, plants take advantage of the surrounding soundscape to flourish, yet how they do this is still unknown. This will be the first experimental study to explore how and why plants sense sound in their environment, hence pioneering a brand-new research area in behavioural and evolutionary ecology.
Animal camouflage patterns. This project aims to understand whether animal camouflage patterns can produce the illusion of 3D form. By using the latest techniques in 3D computer imaging, vision science and animal behaviour, this work addresses the previously untested but fundamental theory on 3D camouflage patterns. The development of theory on the ecology and evolution of animal patterning will enhance our understanding of the processes that maintain biological diversity. This research is expec ....Animal camouflage patterns. This project aims to understand whether animal camouflage patterns can produce the illusion of 3D form. By using the latest techniques in 3D computer imaging, vision science and animal behaviour, this work addresses the previously untested but fundamental theory on 3D camouflage patterns. The development of theory on the ecology and evolution of animal patterning will enhance our understanding of the processes that maintain biological diversity. This research is expected to have broad impact across multiple disciplines and will inform novel military defence strategies and contribute to emerging bio-inspired technologies.Read moreRead less
Buffering the ecosystem impact of invasive cane toads. This project aims to address the devastating ecological problems caused by invasive species, by developing a novel approach that does not rely upon eradicating the invader through training vulnerable native predators not to eat toxic cane toads. Expected outcomes of this project include building a broad coalition of conservation-focused groups, from private land-owners and local businesses through to Indigenous groups and government and non- ....Buffering the ecosystem impact of invasive cane toads. This project aims to address the devastating ecological problems caused by invasive species, by developing a novel approach that does not rely upon eradicating the invader through training vulnerable native predators not to eat toxic cane toads. Expected outcomes of this project include building a broad coalition of conservation-focused groups, from private land-owners and local businesses through to Indigenous groups and government and non-government agencies across the entire Kimberley region. It will also result in the evaluation of methods for deployment of taste-aversion at a landscape scale. This should provide significant benefits by conserving vulnerable fauna and building a powerful network within a region of high biodiversity in tropical Australia.Read moreRead less
Origin and evolution of plant functional traits in relation to fire. This project addresses the fundamental question as to what extent the Australian flora is adapted to fire by tracing the evolutionary history of the iconic family Proteaceae over the last 100 million years. The answer to this question has significant implications for informing Australia’s fire management and nature conservation policies.
