Origins of a biodiversity hotspot flora: diversification of the Australian Proteaceae. Why does Australia's only biodiversity hotspot, with nearly 3000 endemic plant species, occur in an area with poor soils and low rainfall? This project will analyse DNA sequences from over 1000 plant species of the Australian Proteaceae, many found only in this hotspot, to help us understand the evolutionary and ecological origins of this iconic flora.
Evolution of Australia's globally unique hotspot of floral diversity. Australia has a globally recognised biodiversity hotspot, the southwest of Western Australia, but this unique eucalypt-dominated flora is threatened. This project will gain new insights into the evolutionary processes that generate and maintain such diversity, their vulnerability; and how the iconic eucalypts came to dominate the Australian landscape.
New approaches to understanding the forces driving convergent evolution.

This project aims to address the evolutionary biology question of what drives convergent evolution of morphological phenotypes. Leveraging previous research on the phylogenetics of Australian reptiles and amphibians, the project will apply new methodological and analytical tools for quantifying and evaluating morphological diversity in a phylogenetic context. The project expects to test the influence of climate, habitat and evolutionary history on driving convergent morphological evolution across multiple independent animal groups. The project will address fundamental theories on convergent evolution and will improve public awareness of Australia’s unique animals and their history.Read moreRead less
Phenotypic diversity dynamics at a continental scale. This project aims to build on previous research on the phylogenetics of Australian vertebrate animals to apply sophisticated new methodological and analytical tools for modelling species diversification. Australia is famous for the great diversity and uniqueness of its plants and animals, due in part to 40 million years of relative isolation. The project plans to test the influence of historical climate and habitat shifts on morphological evo ....Phenotypic diversity dynamics at a continental scale. This project aims to build on previous research on the phylogenetics of Australian vertebrate animals to apply sophisticated new methodological and analytical tools for modelling species diversification. Australia is famous for the great diversity and uniqueness of its plants and animals, due in part to 40 million years of relative isolation. The project plans to test the influence of historical climate and habitat shifts on morphological evolution and assembly of the Australian biota. This project could showcase Australia as the best place in the World to rigorously test hypotheses concerning rates of biological diversification at a continental scale.Read moreRead less
Improving access to phylogenomic resources for under-resourced species: a new look at existing tools. This project will have an impact on our understanding of how to most effectively use existing genomic resources to benefit a wider range of species and to better design new genomic resources. By doing so, improved access to genomic resources will be provided to species that currently have few options.
Biological diversification across Australia in space and time. This project aims to address fundamental questions about the diversification of Australian species and to have practical and impactful outcomes. It will leverage previous ARC funded research on the phylogenomics of Australian reptiles and amphibians and apply sophisticated analytical tools for quantifying and evaluating biological diversity in multiple dimensions and in a phylogenetic context. The expected outcomes include a publicly ....Biological diversification across Australia in space and time. This project aims to address fundamental questions about the diversification of Australian species and to have practical and impactful outcomes. It will leverage previous ARC funded research on the phylogenomics of Australian reptiles and amphibians and apply sophisticated analytical tools for quantifying and evaluating biological diversity in multiple dimensions and in a phylogenetic context. The expected outcomes include a publicly accessible comprehensive database that will be integrated with the Atlas of Living Australia and rigorous testing of a series of hypotheses concerning how old and recent Australian groups evolved in response to biotic invasions and climate change.

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
Evolutionary history and conservation of an iconic Australian plant group. This project aims to strengthen biodiversity conservation using evolutionary biology. By using new DNA sequencing technologies the project aims to reconstruct the evolutionary history of the diverse and ecologically important plant family Proteaceae.

This project aims to strengthen biodiversity conservation using evolutionary biology. By using new DNA sequencing technologies the project aims to reconstruct the evolutionary history of the diverse and ecologically important plant family Proteaceae. This will be used to discover how past environmental changes have produced the biodiversity we see today, and forecast likely future changes to biodiversity under expected rapid environmental change. The key outcome will be a new methodology for a predictive, forward-looking conservation science that accounts explicitly for the dynamic, evolving nature of biodiversity. The key benefit will be a more robust scientific basis for strategic allocation of limited conservation resources.Read moreRead less
Evolution at extremes: Macroevolutionary responses to harsh environments. The project seeks to investigate the capacity of iconic Australian plant groups (Eucalyptus, Acacia, Banksia, Grevillea, Hakea) to adapt to increases in extreme conditions. Australia presents many extreme conditions for plant survival, such as drought, heat, or salt-affected soils. Are some lineages better able to adapt and diversify in these conditions?

The project seeks to investigate the capacity of iconic Australian plant groups (Eucalyptus, Acacia, Banksia, Grevillea, Hakea) to adapt to increases in extreme conditions. Australia presents many extreme conditions for plant survival, such as drought, heat, or salt-affected soils. Are some lineages better able to adapt and diversify in these conditions? This project aims to develop new methods to identify lineages most tolerant of extreme environments, detect enabling traits that contribute to stress resistance, and test whether plant assemblages in extreme environments are formed from colonisation by specialist tolerators, or by local species adapting. These methods may allow the prediction of species or communities best able to adapt to conditions expected under global environmental change.Read moreRead less
