Biodiversity indicators for better conservation decisions. This project aims to test, design and select biodiversity indicators to support conservation. Reliable and sensitive biodiversity indicators are critical to track progress towards conservation targets, but the ability of most biodiversity indicators to reveal trends needed by decision-makers is untested. This project will test indicators to monitor biodiversity change at local to global scales, by sampling ecosystem models to evaluate ho ....Biodiversity indicators for better conservation decisions. This project aims to test, design and select biodiversity indicators to support conservation. Reliable and sensitive biodiversity indicators are critical to track progress towards conservation targets, but the ability of most biodiversity indicators to reveal trends needed by decision-makers is untested. This project will test indicators to monitor biodiversity change at local to global scales, by sampling ecosystem models to evaluate how indicator design, data bias and environmental variability affect performance. Project outcomes are expected to ensure that that data collected to monitor and assess the state of Australia’s environment are informative, cost-effective and robust. This is expected to have implications for predicting and measuring effects of policy such as the Convention on Biological Diversity.Read moreRead less
Peripheral isolates as hotbeds of adaptive diversity. This project uses cutting edge molecular technology and spatial analyses to predict the location of diversity relevant to managing the impact of climate change. Knowledge generated in this project will open the door to the informed use of genetic translocation in efforts to kerb expected biodiversity losses.
Transformation of vegetation by big herbivores, from the Pleistocene to now. The project aims to provide a coherent understanding of the effects of extinct and extant large herbivores on ecosystems over space and time. The structure and distribution of vegetation types is determined not only by climate and soils, but also by the impacts of herbivores and fire as consumers of plant biomass. Recent research has shown how fire shapes the large-scale distribution of vegetation types, but we do not h ....Transformation of vegetation by big herbivores, from the Pleistocene to now. The project aims to provide a coherent understanding of the effects of extinct and extant large herbivores on ecosystems over space and time. The structure and distribution of vegetation types is determined not only by climate and soils, but also by the impacts of herbivores and fire as consumers of plant biomass. Recent research has shown how fire shapes the large-scale distribution of vegetation types, but we do not have an equivalent understanding of the effects of large ground-dwelling herbivores. The project plans to test the effects of such animals on vegetation structure in the Pleistocene, when mega-herbivores were common, and today, and thus to compare the impacts of fire and herbivores on the distribution of vegetation types.Read moreRead less
Understanding when biocontrol and enemy release affect plant populations. This project aims to determine when introduced species escape from their natural enemies, and when biocontrol efforts succeed. Enemy release and biocontrol are key to our understanding and management of invasions. However there has never been a broad quantitative assessment of the circumstances under which biocontrol and enemy release affect introduced populations. This project will use a combination of meta-analyses and i ....Understanding when biocontrol and enemy release affect plant populations. This project aims to determine when introduced species escape from their natural enemies, and when biocontrol efforts succeed. Enemy release and biocontrol are key to our understanding and management of invasions. However there has never been a broad quantitative assessment of the circumstances under which biocontrol and enemy release affect introduced populations. This project will use a combination of meta-analyses and international field studies to address this knowledge gap. Expected outcomes include a better understanding of the factors that facilitate biological invasions, and improved success of biocontrol agents.Read moreRead less
Forty million Australians: the future of our biodiversity. Many countries have experienced rapid increases in human numbers and natural-resource use. The project will use measured effects on biodiversity from such countries, combined with models of potential changes in Australia's population and climate, to forecast how our biodiversity may be affected up to 2050, and then to plan how to minimize negative impacts.
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.
Enhancing biodiversity and ecosystem services in production landscapes. This project aims to develop new approaches using causal inference, optimal allocation theory, and spatial statistics to characterise impacts on a diverse suite of ecosystem services. It will endeavour to develop case studies from three continents and generalisations explicitly tested using simulated landscapes. Environmental and agricultural policies promote land sharing (biodiversity-friendly production) or land sparing (p ....Enhancing biodiversity and ecosystem services in production landscapes. This project aims to develop new approaches using causal inference, optimal allocation theory, and spatial statistics to characterise impacts on a diverse suite of ecosystem services. It will endeavour to develop case studies from three continents and generalisations explicitly tested using simulated landscapes. Environmental and agricultural policies promote land sharing (biodiversity-friendly production) or land sparing (protected areas, with yield increases elsewhere). Yet the impacts of such policies in diverse contexts and for multiple outcomes are poorly understood. The project could advance our ability to deliver sustainable outcomes and more effective as well as equitable policies for production landscapes.Read moreRead less
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.
Social and environmental selection on female ornaments and armaments. Darwin's theory of sexual selection is remarkably successful in explaining how elaborate signals evolved in male animals, but it is unclear whether similar processes drive the evolution of female signals. This project aims to conduct empirical and comparative tests of hypotheses for female trait elaboration, capitalising on inter- and intra-specific variation in female signal form, social organisation and signalling environmen ....Social and environmental selection on female ornaments and armaments. Darwin's theory of sexual selection is remarkably successful in explaining how elaborate signals evolved in male animals, but it is unclear whether similar processes drive the evolution of female signals. This project aims to conduct empirical and comparative tests of hypotheses for female trait elaboration, capitalising on inter- and intra-specific variation in female signal form, social organisation and signalling environments. The project could generate new insight into the processes that promote and constrain phenotypic diversity in nature.Read moreRead less
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.

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
