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.
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
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.
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
Evolution in tooth and claw: exploring the relationship between the radiation of marsupial herbivores and late Cenozoic climate change. Establishing how animals responded to past environmental changes is essential for understanding the ecology of modern species and managing them in light of contemporary climatic trends. By applying several novel analytical methods this project will unravel the links between the radiation of Australian marsupials and key stages in climatic evolution.
Illuminating the evolutionary history of Australia’s most iconic animals. This project aims to pinpoint the nature and timing of key steps in macropod history and to test how these link with major climatic and biotic changes. Macropods (kangaroos and relatives) are widely considered the marsupial equivalents to hoofed mammals on other continents, but we have a weaker understanding of how their evolution was shaped by environmental change. This project will combine palaeontology, anatomy and gene ....Illuminating the evolutionary history of Australia’s most iconic animals. This project aims to pinpoint the nature and timing of key steps in macropod history and to test how these link with major climatic and biotic changes. Macropods (kangaroos and relatives) are widely considered the marsupial equivalents to hoofed mammals on other continents, but we have a weaker understanding of how their evolution was shaped by environmental change. This project will combine palaeontology, anatomy and genetics to address questions such as how and why ancestral macropods descended from the trees and evolved bipedal hopping, and the upper size limits of the kangaroo “body plan”. This should improve our understanding of the long-term effects of climate change on marsupials, and provide a test of key placental-based evolutionary models.Read moreRead less

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.
Adaptation to life in the dark: genomic analyses of blind beetles. This project aims to utilise a unique Australian model system based on multiple, independently-evolved subterranean water beetles to explore the adaptive and regressive changes in the genome that occur when surface species colonise subterranean habitats. This project focuses on the evolution of Heat Shock protein (Hsp) genes that play critical roles in adaptation to environmental stress and the process of de-canalisation, the rel ....Adaptation to life in the dark: genomic analyses of blind beetles. This project aims to utilise a unique Australian model system based on multiple, independently-evolved subterranean water beetles to explore the adaptive and regressive changes in the genome that occur when surface species colonise subterranean habitats. This project focuses on the evolution of Heat Shock protein (Hsp) genes that play critical roles in adaptation to environmental stress and the process of de-canalisation, the release of cryptic genetic variation that can allow novel morphologies to evolve in new environments. The project expects to provide further understanding of how species may potentially adapt to environmental stresses in the future, including climate change.Read moreRead less
Is regressive evolution associated with loss of gene function in subterranean animals? This project aims to investigate a fundamental biological process: the evolutionary basis for how non-functional characters, such as eyes in subterranean animals, are lost. It will use a unique model system based on eyeless water beetles, and utilise novel new genomic tools to test whether loss of characters results from gene inactivation.
