Testing metabolic theories in ecology. There are striking similarities in the way plants and animals take up and use energy (metabolism), despite enormous variation in size and life-style. This project will make the first experimental comparison of the predictions of the two major theories for these broad patterns. The results will significantly progress this controversial and exciting field.
The ecology of trace metal contamination in native Australian mammals. The ecology of trace metal contamination in native Australian mammals .

The ecology of trace metal contamination in native Australian mammals . This project aims to evaluate the impacts of mined trace metals on the health and performance of native Australian mammals in a northern tropical ecosystem and to determine how each species’ ecology contributes to their risk of contamination. The research also aims to give local Indigenous Rangers scientifically based strategies to improve wildlife conservation on their island. Australia’s long-term health relies on its ability to minimise the environmental costs of mining, particularly in areas characterised by high biodiversity, unique native species, or species of cultural or touristic value. Anticipated outcomes are better, more targeted strategies for conservation in mining areas.Read moreRead less
Can muscles tune foot stiffness to enhance efficiency of human locomotion? This project aims to understand the key role that muscles might play in supporting the arch of the foot and determine if this improves the efficiency of human walking and running. The human foot is known to act like a spring to store and return energy during walking and running. The project hypothesises that this function is enhanced by muscular contributions within the foot that act to tune the stiffness of the foot and ....Can muscles tune foot stiffness to enhance efficiency of human locomotion? This project aims to understand the key role that muscles might play in supporting the arch of the foot and determine if this improves the efficiency of human walking and running. The human foot is known to act like a spring to store and return energy during walking and running. The project hypothesises that this function is enhanced by muscular contributions within the foot that act to tune the stiffness of the foot and maximise efficiency of force production. Exploration of how foot stiffness is controlled during human movement is expected to improve our understanding of the evolution of human walking and running and contribute to improving the design of modern footwear.Read moreRead less
A molecular/morphological view of animal evolution based on marsupials. This project aims to provide high-accuracy methods of evolutionary inference extendable to nearly all other organisms. It aims to research the evolution of animal diversity and calibrate evolutionary timescales on a case study of marsupial mammals, and differentiate between internal and external factors that govern animals’ ability to adapt and diversify. The project will collate a large, open-source three-dimensional catalo ....A molecular/morphological view of animal evolution based on marsupials. This project aims to provide high-accuracy methods of evolutionary inference extendable to nearly all other organisms. It aims to research the evolution of animal diversity and calibrate evolutionary timescales on a case study of marsupial mammals, and differentiate between internal and external factors that govern animals’ ability to adapt and diversify. The project will collate a large, open-source three-dimensional catalogue of the evolving marsupial skeleton, which could provide a detailed and publicly accessible narrative of the evolutionary past and future adaptability of Australian marsupials. The proposed development of methods to quantify the effect of past and present biodiversity crises (e.g. environmental change) is expected to inform longer-term conservation planning.Read moreRead less

Building your future: builder-building coevolution in animal architectures. This project aims to reconstruct how animal architectures change throughout time and how this affects body shapes and functions of their builders. By clarifying the biological role of building behaviour this project will assist in predicting long term responses of wildlife, ecosystems and human life to a changing environment. The project expects to be achieved by comparing the structure, assembly and mechanical performan ....Building your future: builder-building coevolution in animal architectures. This project aims to reconstruct how animal architectures change throughout time and how this affects body shapes and functions of their builders. By clarifying the biological role of building behaviour this project will assist in predicting long term responses of wildlife, ecosystems and human life to a changing environment. The project expects to be achieved by comparing the structure, assembly and mechanical performance of animal architectures with animal morphology and performance in a global phylogenetic framework. This is critical for strategic planning of wildlife and landscape management.Read moreRead less
The link between the angiogenesis of live birth and cancer: a lizard model. The possible link between live birth and cancer will be tested in this project. Lizards that express a growth factor that helps the growth of human cancer tumours will be studied to determine the action of the factor in a whole animal and in human cancer cells.
Using performance to predict the survival of threatened mammals. This project aims to use a new mechanistic approach to quantify how the performance of cats and dingoes interacts with habitat complexity to drive population loss of prey species—namely, how the density of obstacles and refuges contributes to prey escape. Expected outcomes include discovering how rocky and savanna habitat structure affect the survival of threatened mammals hunted by cats and dingoes. It will provide a globally cust ....Using performance to predict the survival of threatened mammals. This project aims to use a new mechanistic approach to quantify how the performance of cats and dingoes interacts with habitat complexity to drive population loss of prey species—namely, how the density of obstacles and refuges contributes to prey escape. Expected outcomes include discovering how rocky and savanna habitat structure affect the survival of threatened mammals hunted by cats and dingoes. It will provide a globally customisable model, and inform management of an important Indigenous Protected Area.Read moreRead less
Ecology, morphology and the diversification of Australian lizards. This project aims to determine the factors driving the spectacular radiation of lizards in Australia. To date, most investigations of lizard anatomy have focused exclusively on external characteristics. This project will examine the underlying internal anatomy to investigate whether morphological innovation is associated with enhanced rates of ecological, life-history and species diversification. The project expects to shed light ....Ecology, morphology and the diversification of Australian lizards. This project aims to determine the factors driving the spectacular radiation of lizards in Australia. To date, most investigations of lizard anatomy have focused exclusively on external characteristics. This project will examine the underlying internal anatomy to investigate whether morphological innovation is associated with enhanced rates of ecological, life-history and species diversification. The project expects to shed light on the evolution of Australia’s most diverse vertebrate lineage, and provide comparative data with which to interpret the lizard fossil record in Australia, and the range declines and relative extinction risks of native lizard species.Read moreRead less
Testing our knowledge on the dawn of animal life: evidence from the fossil record against modern ecological and morphological analogues. The Cambrian 'Explosion', half a billion years ago, is regarded as one of the most important events in the history of the Earth, when most major animal groups first appear in the rock record, and for which South Australia has recently become a significant source of spectacular fossils. However, important questions remain regarding their Ediacaran roots, the spe ....Testing our knowledge on the dawn of animal life: evidence from the fossil record against modern ecological and morphological analogues. The Cambrian 'Explosion', half a billion years ago, is regarded as one of the most important events in the history of the Earth, when most major animal groups first appear in the rock record, and for which South Australia has recently become a significant source of spectacular fossils. However, important questions remain regarding their Ediacaran roots, the speed of evolution at the time, and the environments in which the radiation took place. Studying the fossil evidence in the light of present-day ecological frameworks, and in comparison with modern behavioural and morphological analogues, as well as living relatives, can help us better assess our understanding of this first radiation of animals.Read moreRead less
