The evolution of insect genitalia: phallic reversal in Australian praying mantids. This project will enhance our knowledge of the evolutionary processes that drive biodiversity within species and speciation itself. These issues are fundamental to evolutionary biology, and are of great interest for the general public. We have been extraordinarily successful in communicating our research to the public via natural history articles and films. We will continue to generate high impact publications fro ....The evolution of insect genitalia: phallic reversal in Australian praying mantids. This project will enhance our knowledge of the evolutionary processes that drive biodiversity within species and speciation itself. These issues are fundamental to evolutionary biology, and are of great interest for the general public. We have been extraordinarily successful in communicating our research to the public via natural history articles and films. We will continue to generate high impact publications from this research that will increase the international research profile of Australia in the scientific community. This project will establish international collaborations between Australia and the University of Exeter in Cornwall (UK) and provide employment and high quality training to a research associate and a research assistant.

Placental nutrient transport shows how complex traits evolve. This project aims to use amino acid transport in the vertebrate placenta as a model to demonstrate how genes are recruited and modified to produce a major organ. Using an innovative combination of a new technology, selected reaction monitoring, and transcriptomic and molecular approaches, plus carefully selected Australian species pairs, this project will study the evolution of a complex trait (placental amino acid transport). The pr ....Placental nutrient transport shows how complex traits evolve. This project aims to use amino acid transport in the vertebrate placenta as a model to demonstrate how genes are recruited and modified to produce a major organ. Using an innovative combination of a new technology, selected reaction monitoring, and transcriptomic and molecular approaches, plus carefully selected Australian species pairs, this project will study the evolution of a complex trait (placental amino acid transport). The project will provide fundamental advances in our knowledge of the nutrient transport during pregnancy that is required to produce a healthy baby.Read moreRead less
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.
The evolution of caste determination systems in termites. Termites cause around a billion dollars of damage in Australia each year. To date, all this damage is from native species, but there is the constant threat of invasion by voracious exotics. This project will provide fundamental knowledge on the mechanism termites use to produce the distinctive worker and royal castes, and on the way colony budding arises via juvenile reproduction. This will provide the basis for novel and highly specific ....The evolution of caste determination systems in termites. Termites cause around a billion dollars of damage in Australia each year. To date, all this damage is from native species, but there is the constant threat of invasion by voracious exotics. This project will provide fundamental knowledge on the mechanism termites use to produce the distinctive worker and royal castes, and on the way colony budding arises via juvenile reproduction. This will provide the basis for novel and highly specific termite control methods that target caste determination. The existence of sterile, altruistic castes famously posed a conundrum for Darwin. This project is ground-breaking because it will provide the critical link between the theory that explains the puzzle (kin selection) and molecular biology.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.
