This project aims to address the sourcing of native seed for ecological restoration under global change. The great demand for native seed to deliver ecological restoration provides a clear need and responsibility to use this seed as efficiently as possible. This project expects to develop detailed new knowledge that links plant and environmental genomics, plant physiology, seed and soil biology in embedded experiments at post-mining rehabilitation sites. Expected outcomes include clear industry guidelines that refine seed sourcing strategies for ecological restoration for current and future climates. This should provide significant benefits for improved ecological restoration outcomes when using native seed today and into the future.Read moreRead less
Fire regimes and demographic responses interact to threaten woody species. 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 pla ....Fire regimes and demographic responses interact to threaten woody species. 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
Indian Ocean Climate Change: Ningaloo Reef, a litmus test for the survival of coral reefs. Coral reefs are at the frontline from the effects of rapidly rising levels of carbon dioxide that is causing both global warming and oceans to become more acid-like. Our research program will determine how the survival of one of the World’s most pristine and best preserved coral reefs, Ningaloo Reef, is linked to the response of Australia’s Indian Ocean to climate change. For the first time, we will simula ....Indian Ocean Climate Change: Ningaloo Reef, a litmus test for the survival of coral reefs. Coral reefs are at the frontline from the effects of rapidly rising levels of carbon dioxide that is causing both global warming and oceans to become more acid-like. Our research program will determine how the survival of one of the World’s most pristine and best preserved coral reefs, Ningaloo Reef, is linked to the response of Australia’s Indian Ocean to climate change. For the first time, we will simulate realistic ‘future’ conditions and see how actual coral reef systems respond. This will provide a ‘yardstick’ against which the best-case survival potential of the world’s coral reefs can be assessed, critical for underpinning the urgently needed action to reduce greenhouse gas emissions if we are to ensure the survival of coral reefs.Read moreRead less

Eggshells: genetic and biochemical information encapsulated. Tough, waterproof and impervious to decay, extraordinary eggshell can do more than just project baby birds: DNA from eggshells helps wildlife officers to bust wildlife criminals, scientists to investigate the role of humans and climate change in bird extinctions, and conservationists to save our endangered birds.
Controlling cane toads by turning their own weapons against them. This project aims to prevent cane toads, which are causing ecological havoc across tropical Australia, from breeding successfully. Attempts to control toad populations have had little impact, but recent research has revealed a new possibility — exploiting the toads' own weapons for intraspecific conflict. Larval cane toads compete intensely with other larval cane toads and as a result, have evolved a way to kill off their competit ....Controlling cane toads by turning their own weapons against them. This project aims to prevent cane toads, which are causing ecological havoc across tropical Australia, from breeding successfully. Attempts to control toad populations have had little impact, but recent research has revealed a new possibility — exploiting the toads' own weapons for intraspecific conflict. Larval cane toads compete intensely with other larval cane toads and as a result, have evolved a way to kill off their competitors. Toad tadpoles produce chemicals that have devastating effects on younger members of their own species, but not on native species. By deploying those chemicals, this project could develop a novel and powerful form of invader control.Read moreRead less
Annual rainfall variability and extreme drought over the late Holocene. This project aims to understand long-term rainfall variability for Australia by developing a network of extended, high resolution rainfall records from tree rings. How anthropogenic changes to the atmosphere have influenced changing rainfall patterns across Australia is unclear. By extracting climatic information from tree growth rings across a latitudinal gradient from the subtropical north to the south coast of western Aus ....Annual rainfall variability and extreme drought over the late Holocene. This project aims to understand long-term rainfall variability for Australia by developing a network of extended, high resolution rainfall records from tree rings. How anthropogenic changes to the atmosphere have influenced changing rainfall patterns across Australia is unclear. By extracting climatic information from tree growth rings across a latitudinal gradient from the subtropical north to the south coast of western Australia, the project will extend hydroclimatic records by several centuries, to identify the frequency and extent of extreme droughts across the continent. Outcomes are expected to provide appropriate context for evaluating and adapting to climate change, allowing climate modellers, agricultural producers and other industries to improve forecasts of likely change for risk management.Read moreRead less
The ecology of parasite transmission in fauna translocations. Parasitic diseases pose a threat to the conservation management of Australia's biodiversity. This project will improve our understanding of the impact and transmission of parasites in fauna translocations, contributing to the conservation management of Australian ecosystems by government and private agencies.
Testing current methods for understanding and mitigating inbreeding depression in conservation. Although inbreeding can have serious implications for endangered species, possibly even hastening extinction, the methods currently used to measure inbreeding and reverse its effects have been largely untested. This project will explicitly test the utility of these methods to ensure inbreeding is managed effectively in conservation.

Anticipated outcomes include improved ri ....Resilience of forest ecosystems to multiple stressors in a changing climate. This project will examine the influence of multiple stressors including disease, drought and fire, on the resilience of forest ecosystems within Australia. This project expects to generate new knowledge for land managers and the international community, in management of forest health by determining how soil health and soil fungi influence forest recovery after disturbance events. Anticipated outcomes include improved risk assessment of disturbed forests to future disturbances and significant benefits will include informing climate smart management goals in the recovery of important forest ecosystems, not only for the forest tree species but the animal, plant, insect and microbe communities that depend on these systems.Read moreRead less
The return of the native: reintroductions, reinvasions, and a new paradigm in restoration ecology. We develop a new solution to improve pest control used to protect rare and endangered wildlife by using reintroductions of common native species as a block to reinvasion following pest control. Our approach will significantly reduce the ongoing costs of pest control in Australia and our solution can be used by both large conservation organisations as well as small community groups aiming to control ....The return of the native: reintroductions, reinvasions, and a new paradigm in restoration ecology. We develop a new solution to improve pest control used to protect rare and endangered wildlife by using reintroductions of common native species as a block to reinvasion following pest control. Our approach will significantly reduce the ongoing costs of pest control in Australia and our solution can be used by both large conservation organisations as well as small community groups aiming to control pests and protect key wildlife. Our technique can also be exported to solve alien species problems elsewhere in the world. This work strengthens Australia’s world renowned expertise for research into alien species and ability to develop novel solutions to alien impacts.Read moreRead less
