Why does the genetic nearly-null subspace exist? This project aims to determine why nearly-null genetic subspaces exist by simultaneously measuring the input of new mutational variance in these nearly-null subspaces and the selection that acts on these new mutations to result in the observed low levels of standing genetic variance. The ability of organisms to evolve in response to human disturbance, translocation to new environments, or climate variation is governed by the availability of geneti ....Why does the genetic nearly-null subspace exist? This project aims to determine why nearly-null genetic subspaces exist by simultaneously measuring the input of new mutational variance in these nearly-null subspaces and the selection that acts on these new mutations to result in the observed low levels of standing genetic variance. The ability of organisms to evolve in response to human disturbance, translocation to new environments, or climate variation is governed by the availability of genetic variation. Recent advances in multivariate genetic analysis have demonstrated that a substantial proportion of a phenotype described by quantitative traits has very little genetic variance associated with it, and will therefore tend to be subjected to evolutionary limitsRead moreRead less

Summary
Adaptive evolution and its demographic consequences today. This project aims to provide the first test of whether the rate of adaptative genetic evolution has changed in the recent decades, to quantify how much recent genetic evolution helps animal populations survive, and to increase the ability to study on-going genetic evolution in Australian wildlife. The project is of major significance as many species are currently threatened, or invading, due to rapid environmental changes, in particular ....Adaptive evolution and its demographic consequences today. This project aims to provide the first test of whether the rate of adaptative genetic evolution has changed in the recent decades, to quantify how much recent genetic evolution helps animal populations survive, and to increase the ability to study on-going genetic evolution in Australian wildlife. The project is of major significance as many species are currently threatened, or invading, due to rapid environmental changes, in particular climate change. The anticipated outcome of the project is to deliver new methods, establish a network of international and national collaborators and improve the ability to measure and to forecast how Australian animals adapt to rapidly changing environments.Read moreRead less
