The energetic basis to seed longevity and storage. This project aims to quantify patterns of metabolic rate in Australian native seeds to research seed ecology, dormancy, germination, longevity and persistence in natural and artificial seed banks. The project aims to optimise and refine current respirometry technology for use with native seeds, understand the allometric relationship and patterns with seed diversity, and apply this knowledge to benefit restoration and conservation seed banks. By interpreting the energetics of seeds in a phylogenetic context, this project will develop an experimental protocol to predict the physiology and longevity, and test the viability of seeds in storage. Anticipated outcomes are improved efficiency of seed bank storage, conservation and restoration efforts.Read moreRead less

Maintenance of high plant diversity in phosphorus-impoverished ecosystems. This project aims to determine the role of soil-inhabiting pathogens and symbiotic fungi in the maintenance of plant diversity in Australia’s hyperdiverse shrublands. These are among the world’s most species-rich systems, yet occur on extremely poor soils. This project tests the hypothesis that plants that are best adapted to acquire phosphorus in these extremely infertile soils are most susceptible to soil pathogens. Thi ....Maintenance of high plant diversity in phosphorus-impoverished ecosystems. This project aims to determine the role of soil-inhabiting pathogens and symbiotic fungi in the maintenance of plant diversity in Australia’s hyperdiverse shrublands. These are among the world’s most species-rich systems, yet occur on extremely poor soils. This project tests the hypothesis that plants that are best adapted to acquire phosphorus in these extremely infertile soils are most susceptible to soil pathogens. This trade-off would equalise differences in competitive abilities among plant species and promote high plant diversity. The project will help elucidate how pathogens and symbiotic fungi together drive plant diversity in a globally significant biodiversity hotspot in Australia, with relevance to other biodiverse regions.Read moreRead less
Ecological forecasts of species response to fire, drought and heatwaves. This project will advance ecosystem forecasting by accounting for how legacy effects from extreme environmental events – prolonged droughts, floods, heatwaves and fires – persist into future years in vulnerable dryland ecosystems. As highly stressed environments are expected to leave increasingly large impacts on flora and fauna and exacerbate desertification, answers are urgently needed to understand and mitigate these imp ....Ecological forecasts of species response to fire, drought and heatwaves. This project will advance ecosystem forecasting by accounting for how legacy effects from extreme environmental events – prolonged droughts, floods, heatwaves and fires – persist into future years in vulnerable dryland ecosystems. As highly stressed environments are expected to leave increasingly large impacts on flora and fauna and exacerbate desertification, answers are urgently needed to understand and mitigate these impacts. This project will foster new appreciation of ecosystem features that build resilience to change, or that lead to collapse. Benefits include better forecasting tools to manage ecosystems at risk, improved security of biodiversity and food production in Australian rangelands, and training of early career researchers.Read moreRead less
Consequences of temporal community turnover. This project aims to understand how environmental change affects compensatory dynamics of species. Species numbers do not change over time in local ecological communities, but species composition is changing at an unprecedented level across the globe. The implications of these compensatory dynamics for the resilience of ecological communities and how they affect ecosystems are important for community ecology and conservation. This project could reveal ....Consequences of temporal community turnover. This project aims to understand how environmental change affects compensatory dynamics of species. Species numbers do not change over time in local ecological communities, but species composition is changing at an unprecedented level across the globe. The implications of these compensatory dynamics for the resilience of ecological communities and how they affect ecosystems are important for community ecology and conservation. This project could reveal the functional consequences of temporal community change, contributing new insights into the effects of environmental change especially on soil ecosystems.Read moreRead less
Predicting climate change impacts on biodiversity: testing and applying new approaches. A primary challenge faced by Australia is predicting the threat that climate change will have on biodiversity. This project will dramatically improve our ability to manage threats to biodiversity posed by climate change by studying plant species at warmer latitudes, where they are already experiencing predicted future climate conditions.

This project aims to extend and test an Interval Squeeze conceptual model which predicts fire-climate interaction effects on plant species persistence. Complex processes affect future species persistence, and an evidence-based conceptual framework is needed. Working across two continents, this project will quantify the effects of projected shortening of fire intervals, lower rainfall and elevated temperatures on woody plant species. Field evidence spans global change predictions, ecosystems and species representing key system dominants and functional response types. The project will synthesise this data into larger simulation models and extend its conceptual framework to directly inform conservation and fire management.Read moreRead less
