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?

Evolving rates: foundations for the next generation of molecular clocks. This project aims to investigate the causes and consequences of variation in rate of DNA sequence evolution across three kingdoms of life. Dates estimated from DNA sequences have a wide range of applications, including evolutionary biology, conservation prioritisation and epidemiology. These methods rely on accurate rate estimates, but current models lack information about the biological drivers of rates of genomic change. ....Evolving rates: foundations for the next generation of molecular clocks. This project aims to investigate the causes and consequences of variation in rate of DNA sequence evolution across three kingdoms of life. Dates estimated from DNA sequences have a wide range of applications, including evolutionary biology, conservation prioritisation and epidemiology. These methods rely on accurate rate estimates, but current models lack information about the biological drivers of rates of genomic change. This project will test reliability of current methods, identify potentially misleading estimates of disease origin or conservation priorities, and develop new approaches with empirically-informed models of rate change.Read moreRead less
Linking Stress Tolerance to Molecular Evolution of Grass Stomata. Salinity and drought are two detrimental environmental stresses, affecting agricultural productivity and ecosystem health in Australia and around the world. This project will focus on the evolutionary, physiological and molecular aspects of stomatal regulation between wheat, barley and their wild relatives for salinity and drought tolerance. This project will advance the scientific knowledge in the evolution of stomatal regulation ....Linking Stress Tolerance to Molecular Evolution of Grass Stomata. Salinity and drought are two detrimental environmental stresses, affecting agricultural productivity and ecosystem health in Australia and around the world. This project will focus on the evolutionary, physiological and molecular aspects of stomatal regulation between wheat, barley and their wild relatives for salinity and drought tolerance. This project will advance the scientific knowledge in the evolution of stomatal regulation in two staple crops wheat and barley. The project will also assist plant breeders with increasing crop salinity and drought tolerance for global food security.Read moreRead less

Summary
Linking genomic changes to the generation of biodiversity. This project aims to provide a suite of theories, methods and software to enhance our understanding on how the generation of variation at molecular level is linked to the generation of species richness at lineage level. This new approach tests various ways that molecular changes are manifested as patterns of diversification, as revealed by genomic data analysed at the lineage level in phylogenetic studies. Expected outcomes of this proje ....Linking genomic changes to the generation of biodiversity. This project aims to provide a suite of theories, methods and software to enhance our understanding on how the generation of variation at molecular level is linked to the generation of species richness at lineage level. This new approach tests various ways that molecular changes are manifested as patterns of diversification, as revealed by genomic data analysed at the lineage level in phylogenetic studies. Expected outcomes of this project add to a growing body of evolutionary theory and provide practical phylogenetic tools for future analyses. These should benefit Australia by improving our understanding on the formation of Australia’s biodiversity hotspots.Read moreRead less
