How are visual gene pathways lost and restored during reptile evolution? This project aims to investigate how complex traits are lost during evolution, and once lost if they can be regained. The project will use the diverse visual systems of snakes and lizards to shed light on the process of gene loss in degenerative lineages, and discover the mechanisms that compensate for gene losses in taxa with secondarily evolved visual capabilities- providing a case of evolutionary re-innovation in complex ....How are visual gene pathways lost and restored during reptile evolution?

This project aims to increase understanding of how Australia’s native biota responds to rapid environmental changes. Abrupt environmental change has the potential to drive rapid evolution, which may facilitate species persistence in the face of novel challenges. This project will use long-term genomic data to quantify rates of evolutionary change in species living in arid environments, whose populations fluctuate markedly in response to rainfall variation. By measuring the pace of genomic change in these species, and the evolutionary processes driving that change, this project will reveal species’ evolutionary responses to major environmental fluctuations.Read moreRead less

The evolution of specialised orchid pollination and its reversibility. This project aims to determine the changes in key floral volatile compounds underpinning pollination transitions, identify their molecular basis, and understand the ecological processes favouring reversals away from extreme specialisation. By focusing on pollination of sexually deceptive Australian orchids, this project would be the first to determine the molecular, chemical and behavioural basis of evolutionary reversals to ....The evolution of specialised orchid pollination and its reversibility. This project aims to determine the changes in key floral volatile compounds underpinning pollination transitions, identify their molecular basis, and understand the ecological processes favouring reversals away from extreme specialisation. By focusing on pollination of sexually deceptive Australian orchids, this project would be the first to determine the molecular, chemical and behavioural basis of evolutionary reversals to more generalised strategies in a group of plants facing high risk of pollinator extinction. The expected outcome, a mechanistic understanding of how pollination transitions occur, would be internationally ground-breaking, and provide crucial insights to protect this diverse but highly threatened group of plants.Read moreRead less
