This project aims to address how animals adapt to environmental change by examining a process largely ignored in current studies: how the environment alters animal development. This project expects to generate new knowledge in the area of the genetics of adaptation using an innovative approach to determine how genetic variation, environmental conditions, and development interact to shape adaptation to changing environments. Expected outcomes of this project include enhancing predictions of how species respond to climate change and building capacity for international collaborations. The intended impact of this project is to increase our understanding of how animals respond to environmental change by determining how multiple environmental cues act together to alter development, and how the genetic makeup of the individual affects these responses.Read moreRead less
Evolutionary impacts of gene interactions in a rapidly changing world. This project aims to understand how gene interactions impact evolution in our warming marine environments. The role of gene interactions is controversial because they are assumed to have little effect on genetic variation for fitness in natural populations. Yet new data show that this effect can be substantial and is enhanced by heat stress, explaining most of the genetic variation available for evolution under stressful cond ....Evolutionary impacts of gene interactions in a rapidly changing world. This project aims to understand how gene interactions impact evolution in our warming marine environments. The role of gene interactions is controversial because they are assumed to have little effect on genetic variation for fitness in natural populations. Yet new data show that this effect can be substantial and is enhanced by heat stress, explaining most of the genetic variation available for evolution under stressful conditions. The project aims to use quantitative genetics, genomics, and theory to determine the evolutionary impacts on marine populations facing rapid ocean warming in southeast Australia. The outcomes could change how we view gene interactions, and help us to better predict biological responses to environmental change.Read moreRead less
Understanding the ecological effects of genetic diversity: causes, consequences and relative importance. This project will examine the effect of genetic diversity on key demographic parameters (for example, population growth rates) for organisms from three groups, including a commercially important oyster. This project provides valuable information that can be used by managers of wild and cultivated populations to minimise impacts of human activities and maximise yields.
Targeted gene flow for conservation. This project aims to develop targeted gene flow as a broad conservation strategy, exploiting natural geographic variation to achieve conservation outcomes. Geographic variation and local adaptation are ubiquitous within species, but conservation managers do not use this heritable variation. The project will develop decision tools to address when to time a targeted gene flow action, and where to source appropriate genetic variation. As case studies, the projec ....Targeted gene flow for conservation. This project aims to develop targeted gene flow as a broad conservation strategy, exploiting natural geographic variation to achieve conservation outcomes. Geographic variation and local adaptation are ubiquitous within species, but conservation managers do not use this heritable variation. The project will develop decision tools to address when to time a targeted gene flow action, and where to source appropriate genetic variation. As case studies, the project will try to use targeted gene flow to halt the invasion of the cane toad in northern Australia and reverse the decline of northern quolls.Read moreRead less
Do hotter and drier regions harbour adaptive variation for climate change? This project aims to improve our understanding of the capacity of trees to respond to climate change. This is essential for the maintenance of biodiversity, forest health and productivity. In south-west Australia, climate variation has increased the frequency and intensity of droughts, which has resulted in tree death and negatively affected essential ecosystem services. Adaptive land management is urgently needed to miti ....Do hotter and drier regions harbour adaptive variation for climate change? This project aims to improve our understanding of the capacity of trees to respond to climate change. This is essential for the maintenance of biodiversity, forest health and productivity. In south-west Australia, climate variation has increased the frequency and intensity of droughts, which has resulted in tree death and negatively affected essential ecosystem services. Adaptive land management is urgently needed to mitigate the risk of large-scale drought mortality in a rapidly changing climate. This project seeks to deliver a scientific basis for the adoption of assisted gene migration in south-west forests, through a detailed understanding of genetic adaptation and physiological tolerance, to improve drought-resilience under future hotter and drier climates.Read moreRead less
Clinal variation in drosophila; a signature of climatic adaptation and a resource for adaptive gene discovery. Evolutionary changes can occur rapidly within populations and genetic changes in traits along gradients represent an expression of these rapid changes. The east coast of Australia represents an outstanding natural laboratory to understand these changes using drosophila flies as model systems.

Summary
Genetic and epigenetic drivers of the Australian cane toad invasion. Although invasive species are a massive threat to biodiversity, and costly to society, we still do not understand the evolutionary processes that shape invasions. Invasive populations often show rapid evolutionary change in novel environments but attempts to identify the underlying genetic mechanisms have been largely unsuccessful. This project aims to explore an innovative and untested alternative possibility: that invader evo ....Genetic and epigenetic drivers of the Australian cane toad invasion. Although invasive species are a massive threat to biodiversity, and costly to society, we still do not understand the evolutionary processes that shape invasions. Invasive populations often show rapid evolutionary change in novel environments but attempts to identify the underlying genetic mechanisms have been largely unsuccessful. This project aims to explore an innovative and untested alternative possibility: that invader evolution is primarily driven by epigenetic change. Using an iconic Australian invasive species, the cane toad, the project aims to quantify genetic and epigenetic change across the invasion and use manipulative experiments to determine the influence of epigenetic change on the evolution of phenotypic traits important to invasion.Read moreRead less
Does dynamic ecological change cause rapid 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 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
