Understanding how cells compact and segregate DNA in vertebrates. How a cell compacts and divides its DNA is still a major unanswered question in biology. This project will determine the way in which a cell compacts its DNA nearly ten thousand fold to allow the faithful and accurate segregation to daughter nuclei.
Predicting the movement speeds of animals. The project seeks to reveal how marsupials modify their movement patterns and speeds as they navigate risky environments, and show how movement contributes to vulnerability and resilience. Movement is central to animal behaviour and the survival of species, because it underlies feeding, mating and the ability to escape from predators. However, we lack a framework for predicting how fast animals should move through their habitats given their needs to con ....Predicting the movement speeds of animals. The project seeks to reveal how marsupials modify their movement patterns and speeds as they navigate risky environments, and show how movement contributes to vulnerability and resilience. Movement is central to animal behaviour and the survival of species, because it underlies feeding, mating and the ability to escape from predators. However, we lack a framework for predicting how fast animals should move through their habitats given their needs to conserve energy, avoid detection by predators and minimise risks of injury or death. This project aims to develop mathematical models to predict how fast animals should move and then test these predictions using native species of conservation concern. This is expected to extend the field of performance ecology as well as inform management strategies for vulnerable marsupials.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
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 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 nature and consequences of environmentally-generated phenotypic variation in natural populations. The ambient environment can generate both heritable and non-heritable variation in individual traits, but the role of such variation in evolution is poorly understood. This project will use a powerful model organism, the Australian neriid flies, to elucidate the evolutionary implications of environmentally-generated variation.
Lively reproduction: do common molecules underlie all vertebrate live birth? Most animals lay eggs, but some (most mammals, including humans and some reptiles) give birth to live young. This project will reveal the molecules underlying the evolution of live birth and fundamental processes of early pregnancy, which potentially will lead to future developments in reproductive science.
Structural domains of beta-tubulin and their role in microtubule dynamics and transport. This study aims to obtain a fundamental understanding of how the structural domains of the cytoskeletal protein beta-tubulin are involved in microtubule structures during cell division and vesicular transport. Using gene-editing technology and coupling this with cell biological approaches and high-resolution cell imaging will enable detailed analysis of the role of beta-tubulin domains in these important cel ....Structural domains of beta-tubulin and their role in microtubule dynamics and transport. This study aims to obtain a fundamental understanding of how the structural domains of the cytoskeletal protein beta-tubulin are involved in microtubule structures during cell division and vesicular transport. Using gene-editing technology and coupling this with cell biological approaches and high-resolution cell imaging will enable detailed analysis of the role of beta-tubulin domains in these important cellular processes. The outcomes will include fundamental new knowledge in cell biology and lead to the development of unique biological models that can be used to understand disease.Read moreRead less
The origins of electroreception and nocturnality in the earliest known jawed vertebrates and their bearing on vertebrate diversification. This project aims to discover primary new data to pinpoint the timing, anatomical origins and phylogenetic significance when two key sensory systems first appeared in modern vertebrates: electroreception and specialised nocturnal vision. Such abilities today allow high diversity of vertebrates to co-exist within the same geographical range, for example on trop ....The origins of electroreception and nocturnality in the earliest known jawed vertebrates and their bearing on vertebrate diversification. This project aims to discover primary new data to pinpoint the timing, anatomical origins and phylogenetic significance when two key sensory systems first appeared in modern vertebrates: electroreception and specialised nocturnal vision. Such abilities today allow high diversity of vertebrates to co-exist within the same geographical range, for example on tropical reefs or rainforest communities, through careful temporal niche partitioning where reliance on other sensory systems takes over from vision and olfaction as the principal method of prey detection. This project aims to elucidate how the modern fish diversity was shaped by such significant early evolutionary events.Read moreRead less
