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
Unravelling the principles of bilateral brain wiring. This project seeks to investigate the molecular principles of brain wiring in mammals and how small changes can generate complex outcomes. Neurons in the mammalian brain must be precisely wired together for the brain to function correctly. The project aims to identify the molecular and cellular rules governing commissural wiring in the mammalian cortex to determine how the largest fibre tract in the human brain, the corpus callosum, evolved. ....Unravelling the principles of bilateral brain wiring. This project seeks to investigate the molecular principles of brain wiring in mammals and how small changes can generate complex outcomes. Neurons in the mammalian brain must be precisely wired together for the brain to function correctly. The project aims to identify the molecular and cellular rules governing commissural wiring in the mammalian cortex to determine how the largest fibre tract in the human brain, the corpus callosum, evolved. This may have involved modifications in mechanisms affecting axon guidance that differ between placentals and marsupials. The project investigates the regulatory gene networks determining commissural neuron fate, the regulation of axon guidance components, and the influence of surrounding brain tissue on the development of commissural connections.Read moreRead less

Summary
Skulls as machines: diversity and evolution in a group of charismatic Australian lizards. This project uses sophisticated computer software to analyse how the complex skulls of dragon lizards work. This will provide a greater understanding of the factors underlying their evolution and radiation in Australia where they are one of the most successful lizard groups and a vital part of the desert fauna.
Normal heart development before birth. This project aims to understand how the fetal heart can develop normally with much less oxygen than an adult heart uses. Regulation of fetal heart proliferation is not well understood but changes in oxygen levels and non-coding RNAs are implicated. Using advanced imaging techniques to measure blood flow in blood vessels to the fetal heart and molecular probes to assess cell function and microarrays to measure non-coding RNA, the project expects to generate ....Normal heart development before birth. This project aims to understand how the fetal heart can develop normally with much less oxygen than an adult heart uses. Regulation of fetal heart proliferation is not well understood but changes in oxygen levels and non-coding RNAs are implicated. Using advanced imaging techniques to measure blood flow in blood vessels to the fetal heart and molecular probes to assess cell function and microarrays to measure non-coding RNA, the project expects to generate new knowledge about mechanisms of fetal heart cell proliferation. Ultimately, this new knowledge could lead to non-invasive approaches to detect and treat abnormal fetal heart growth in animals and humans.Read moreRead less
Going with the flow: directing nutrient rich blood to the brain. This project aims to visualise and measure flow of blood from the umbilical cord to the fetal brain and to understand how delivery of oxygen and glucose to the brain is prioritised by constriction or relaxation of a specialised shunt, the ductus venosus. The project will directly and non-invasively measure this fundamental phenomenon with novel MRI protocols. Expected outcomes of this project include advances in measuring fetal blo ....Going with the flow: directing nutrient rich blood to the brain. This project aims to visualise and measure flow of blood from the umbilical cord to the fetal brain and to understand how delivery of oxygen and glucose to the brain is prioritised by constriction or relaxation of a specialised shunt, the ductus venosus. The project will directly and non-invasively measure this fundamental phenomenon with novel MRI protocols. Expected outcomes of this project include advances in measuring fetal blood flow and the exchange of expertise between leading researchers in Australia and Canada. In the long-term, this will enhance Australia’s research capacity in fetal physiology and may lead to new tools for monitoring or supporting fetal development.Read moreRead less
The developmental genetics of major evolutionary transitions: a multidisciplinary investigation of limb reduction and loss in lizards. The five-toed limb is an iconic evolutionary innovation of land vertebrates, yet has been lost repeatedly. This project will use anatomical, developmental and genetic approaches to understand how vertebrates lose their legs, whether limbs can be reacquired, and the degeneration of limb genes after they lose their function (analogous to 'vestigial organs').
