This project aims to make drone technology a viable solution for scaling up the restoration of native vegetation on degraded land. By integrating new research in plant ecology, microbiology and environmental economics the project aims to fill key knowledge gaps about the viability and application of drones in restoration. Expected outcomes are world-first research into the delivery of beneficial soil microbes using drones and the first assessment globally of the cost-effectiveness of drone restoration utilizing data from spatial analysis and extensive field trials. This should provide wide-ranging benefits for local land managers restoring remote degraded land and aid in reversing the cumulative effects of habitat loss on biodiversity. Read moreRead less
Feast or famine: how Australian plants stay productive under low phosphorus. Phosphorus (P) is in low supply in soils around the nation, and limits plant production in the Australian landscape, as well as for many tropical forests worldwide. How scarce P restricts photosynthetic capacity has remained elusive. We will determine how Australian plants achieve high phosphorus-use efficiency despite low P concentrations in leaves and soils. We will synthesise knowledge of how plants maintain producti ....Feast or famine: how Australian plants stay productive under low phosphorus. Phosphorus (P) is in low supply in soils around the nation, and limits plant production in the Australian landscape, as well as for many tropical forests worldwide. How scarce P restricts photosynthetic capacity has remained elusive. We will determine how Australian plants achieve high phosphorus-use efficiency despite low P concentrations in leaves and soils. We will synthesise knowledge of how plants maintain productivity with low P availability, and inform global models how to represent P biogeochemistry and photosynthesis to improve C-cycle estimates. The understanding of plant photosynthetic and P-saving mechanisms that emerge should provide benefits through improved ecological models and enhanced management of primary production.Read moreRead less
Weathering the perfect storm: mitigating the post-fire impacts of invasive predators on small desert vertebrates. Wildfires deplete food and shelter resources for many native vertebrates, exposing them to increased predation from invasive predators such as the red fox and feral cat. Focusing on the fire-prone spinifex grasslands of central Australia, this project firstly identifies the role of specific refuge habitats that provide native species with protection in the post-fire environment, and ....Weathering the perfect storm: mitigating the post-fire impacts of invasive predators on small desert vertebrates. Wildfires deplete food and shelter resources for many native vertebrates, exposing them to increased predation from invasive predators such as the red fox and feral cat. Focusing on the fire-prone spinifex grasslands of central Australia, this project firstly identifies the role of specific refuge habitats that provide native species with protection in the post-fire environment, and then proposes an innovative experimental program to quantify and mitigate predation-impacts. The results will stimulate new thinking about predator-prey theory and, in an environment predicted to experience more wildfires in future, provide guidance about how to protect the rich biotic resources of the continental interior.

Do microbial and plant diversity interact to regulate multifunctionality? This project aims to quantify the relative contribution of plant and microbial communities and their interactions on the rate, stability and resilience of ecosystem functions. Plant and soil microbial communities contribute to the functioning of terrestrial ecosystems, driving key processes such as carbon and nutrient cycling. This project will adapt established theories which indicate that greater plant diversity improves ....Do microbial and plant diversity interact to regulate multifunctionality? This project aims to quantify the relative contribution of plant and microbial communities and their interactions on the rate, stability and resilience of ecosystem functions. Plant and soil microbial communities contribute to the functioning of terrestrial ecosystems, driving key processes such as carbon and nutrient cycling. This project will adapt established theories which indicate that greater plant diversity improves ecosystem functions, stability and recovery. The expected outcome is a unifying framework for determining variation in functions across different ecosystem types and environmental disturbance such as rapid climate change.The insight gained into vulnerable ecosystems will help stakeholders (government, conservation, land management) to prioritise the focus on conservation and reduce risks to ecosystem services.Read moreRead less

Summary
How species interactions shape range boundaries. This project aims to discover how biotic interactions limit plant species distributions. This knowledge is crucial for improving models of plant response to climate and land-use change. Current modelling techniques routinely ignore interactions such as competition, focusing solely on the environment as a predictor of species range. Using trait-based analyses at a continental scale and targeted transplant experiments, this project aims to better un ....How species interactions shape range boundaries. This project aims to discover how biotic interactions limit plant species distributions. This knowledge is crucial for improving models of plant response to climate and land-use change. Current modelling techniques routinely ignore interactions such as competition, focusing solely on the environment as a predictor of species range. Using trait-based analyses at a continental scale and targeted transplant experiments, this project aims to better understand range limits of Australian plant species. This approach is expected to improve the ability to identify which plants will be the 'winners and losers' as the climate changes and to manage the risk to Australia’s flora.Read moreRead less
Get tough, get toxic or get a bodyguard: how root herbivores shape grass defences. The weight of root-feeding beetles can exceed that of sheep on Australian pastures and can result in significant losses in productivity. Grasses fight back against aboveground herbivores using toughness (physical defence), toxicity (chemical defence) and bodyguards (recruitment of the herbivore’s enemies). Little is known about belowground defences however, but grasses depend on roots for re-growth so good root de ....Get tough, get toxic or get a bodyguard: how root herbivores shape grass defences. The weight of root-feeding beetles can exceed that of sheep on Australian pastures and can result in significant losses in productivity. Grasses fight back against aboveground herbivores using toughness (physical defence), toxicity (chemical defence) and bodyguards (recruitment of the herbivore’s enemies). Little is known about belowground defences however, but grasses depend on roots for re-growth so good root defences seem essential. This study will apply optimal defence theory to consider these three defences against belowground herbivory across a range of grasses. The project will ask whether domestication has disarmed grass species and if defensive traits differ between photosynthetic pathways, before field-testing these patterns with root herbivore populations.

Buffering the ecosystem impact of invasive cane toads. This project aims to address the devastating ecological problems caused by invasive species, by developing a novel approach that does not rely upon eradicating the invader through training vulnerable native predators not to eat toxic cane toads. Expected outcomes of this project include building a broad coalition of conservation-focused groups, from private land-owners and local businesses through to Indigenous groups and government and non- ....Buffering the ecosystem impact of invasive cane toads. This project aims to address the devastating ecological problems caused by invasive species, by developing a novel approach that does not rely upon eradicating the invader through training vulnerable native predators not to eat toxic cane toads. Expected outcomes of this project include building a broad coalition of conservation-focused groups, from private land-owners and local businesses through to Indigenous groups and government and non-government agencies across the entire Kimberley region. It will also result in the evaluation of methods for deployment of taste-aversion at a landscape scale. This should provide significant benefits by conserving vulnerable fauna and building a powerful network within a region of high biodiversity in tropical Australia.Read moreRead less
Origin and evolution of plant functional traits in relation to fire. This project addresses the fundamental question as to what extent the Australian flora is adapted to fire by tracing the evolutionary history of the iconic family Proteaceae over the last 100 million years. The answer to this question has significant implications for informing Australia’s fire management and nature conservation policies.

Dimensions of ecological strategy for plants. A more fundamental understanding will be sought about the architecture and ecology of vegetation and why it varies around the world. Under a high- CO2 future, models will be needed that operate through fundamental mechanisms of evolution, competition and physiology, rather than through extrapolation from present-day plants.
