Adapting to a changing world: mothers as drivers of evolutionary change. This project will improve our understanding of how organisms will adapt to the unprecedented speed and magnitude of human-induced environmental change. By identifying how mothers modify their offspring to better match the prevailing environment, it will address the role of mothers in directing and accelerating adaptation in our changing world.
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
Evolution in a changing environment. Climate change is having dramatic effects on wild animal populations. This project will investigate how and why these effects occur, and whether populations will be able to evolve to adapt to a changing environment.

The Evolution of stripe rust virulence. Fungal crop pathogen epidemics lead to severe yield losses worldwide, impact national economies and individual human lives. Wheat stripe rust fungal epidemics caused by new virulent races can lead to 80 per cent reduction in yield. This project aims to investigate the molecular mechanisms leading to newly virulent races by whole genome, epigenome and transcriptome comparison of several wheat stripe rust races. This project aims to fundamentally advance our ....The Evolution of stripe rust virulence. Fungal crop pathogen epidemics lead to severe yield losses worldwide, impact national economies and individual human lives. Wheat stripe rust fungal epidemics caused by new virulent races can lead to 80 per cent reduction in yield. This project aims to investigate the molecular mechanisms leading to newly virulent races by whole genome, epigenome and transcriptome comparison of several wheat stripe rust races. This project aims to fundamentally advance our understanding of evolutionary forces driving virulence and specification at the whole (epi-)genome level in important fungal crop pathogens. This will promote new crop protection strategies important for local and global food security in an ever-changing environment.Read moreRead less
Drivers of phenotypic evolution in a vulnerable alpine ecosystem. This project aims to deliver a comprehensive, integrated understanding of the capacity for resilience and drivers of response of highly vulnerable alpine species and communities to climate change. The project aims to determine how communities of interacting alpine plants, soil invertebrates and microbes can cope with or evolve to novel climatic conditions. The mountains are water towers critical to power supply and Australia's agr ....Drivers of phenotypic evolution in a vulnerable alpine ecosystem. This project aims to deliver a comprehensive, integrated understanding of the capacity for resilience and drivers of response of highly vulnerable alpine species and communities to climate change. The project aims to determine how communities of interacting alpine plants, soil invertebrates and microbes can cope with or evolve to novel climatic conditions. The mountains are water towers critical to power supply and Australia's agricultural productivity. Understanding physiological tolerance and the potential for rapid evolutionary responses of plants, animals and communities is necessary to predict impacts of climate change on the future productivity of the vulnerable Australian Alps and to provide novel options for climate adaptation.

Landscape restoration genomics for climate adaptation in eucalyptus foundation species. Understanding the genetic basis of adaptation in foundation species will allow selection of pre-adapted seeds to establish resilient ecosystems which support the broad range of life supporting services. This project will apply genomics to solve real environmental challenges in restoration management and be a model for other foundation species.

Volcanoes as safe-havens for Antarctic species during ice ages. Understanding how plants and animals responded to past changes in climate can help us to predict what might happen in the future, yet there are key gaps in our knowledge of past processes. Genetic evidence shows that many Antarctic species have been isolated on the continent for millions of years, but during the last Ice Age, Antarctica was blanketed in glaciers. How could species have survived such extreme conditions and how did th ....Volcanoes as safe-havens for Antarctic species during ice ages. Understanding how plants and animals responded to past changes in climate can help us to predict what might happen in the future, yet there are key gaps in our knowledge of past processes. Genetic evidence shows that many Antarctic species have been isolated on the continent for millions of years, but during the last Ice Age, Antarctica was blanketed in glaciers. How could species have survived such extreme conditions and how did they respond to past global warming? This project will analyse genetic diversity patterns to test whether Antarctic species survived ice ages on ice-free land near volcanoes and, capitalising on the unique setting of Antarctica, will give insights into the role of volcanoes in promoting biodiversity in cold regions.Read moreRead less
The origins, global spread and evolution of novel honey bee parasites. This project aims to study how emergent diseases arise, spread and evolve, studying varroa mites – a parasite of honey bees that will inevitably arrive in Australia and is expected to damage agriculture and the environment. As the mites have a well-characterised native range, independent host switches and a well-documented history of spread, they make good models. Mites have evolved after invasion, although without significan ....The origins, global spread and evolution of novel honey bee parasites. This project aims to study how emergent diseases arise, spread and evolve, studying varroa mites – a parasite of honey bees that will inevitably arrive in Australia and is expected to damage agriculture and the environment. As the mites have a well-characterised native range, independent host switches and a well-documented history of spread, they make good models. Mites have evolved after invasion, although without significant genetic differentiation at neutral markers. This project aims to identify genetic mechanisms associated with the host switches; reconstruct the pattern and demography of varroa’s global spread; and determine how selection acted on the mites after the host switch.Read moreRead less
