Linking risks to ecosystems with risks to human well-being. This project aims to provide theory and practical guidelines to integrate ecosystem science into policy and action to address human well-being. Ecosystem risk assessment provides critical information for conservation, and has compelling but unexplored relationships with human health and nature’s benefits to people. The research will identify ecosystem measures that highlight areas of risk to human well-being as well as biodiversity. Exp ....Linking risks to ecosystems with risks to human well-being. This project aims to provide theory and practical guidelines to integrate ecosystem science into policy and action to address human well-being. Ecosystem risk assessment provides critical information for conservation, and has compelling but unexplored relationships with human health and nature’s benefits to people. The research will identify ecosystem measures that highlight areas of risk to human well-being as well as biodiversity. Expected outcomes include new standards for including ecosystem change in policy frameworks globally and in Australia, such as natural capital accounting and United Nations Sustainable Development Goals. Benefits include improved ways of meeting and tracking progress on Australia’s international commitments.Read moreRead less
Cascading effects of Australia's ecological extinctions on biodiversity and ecosystem function. The current rate of species extinctions is so extensive that it has been described as the “sixth mass extinction”. In Australian ecosystems, extinctions and declines of mammals have been dramatic, with formerly abundant species now “ecologically extinct”, meaning they are too rare to continue to play important ecological roles. The loss of entire functional guilds may have cascading effects on biodive ....Cascading effects of Australia's ecological extinctions on biodiversity and ecosystem function. The current rate of species extinctions is so extensive that it has been described as the “sixth mass extinction”. In Australian ecosystems, extinctions and declines of mammals have been dramatic, with formerly abundant species now “ecologically extinct”, meaning they are too rare to continue to play important ecological roles. The loss of entire functional guilds may have cascading effects on biodiversity and ecosystem function. This project uses a multi-scalar experimental approach to investigate the broader impacts of mammal declines on Australian ecosystems, accounting for interactions with climate. The outcomes will include new insights into the pre-European state of Australian ecosystems and more realistic targets for ecosystem restoration.Read moreRead less
From prediction to adaptation: responding to rapid ecosystem shifts under climate change. Nobody knows exactly how climate change will affect the ecosystems on which we depend for our own existence, though negative impacts are widely predicted. This project integrates mathematical, economic and ecological approaches to learn about the most effective way to spend limited funds for sustaining ecosystems threatened by climate change.
Vulnerability of Australian savannas to climate change and variability. Australian savannas are productive and are culturally and biologically significant landscapes, but they are vulnerable to climate change. This project will determine savanna function (carbon and water balance) for the present and assess how sensitive they have been to past climate variability. The project will then address how they may respond to future climate change.
Tracking the molecular dynamics of adaptation with horizontal gene transfer. This project aims to track the dynamics of adaptation with gene exchange by building the first experimental evolution model that can directly observe this process. The acquisition of genes from other strains and species (horizontal gene transfer) frequently underlies bacterial adaptation, but it is unknown how this occurs. This project aims to shift understanding of how microbial populations respond to environmental cha ....Tracking the molecular dynamics of adaptation with horizontal gene transfer. This project aims to track the dynamics of adaptation with gene exchange by building the first experimental evolution model that can directly observe this process. The acquisition of genes from other strains and species (horizontal gene transfer) frequently underlies bacterial adaptation, but it is unknown how this occurs. This project aims to shift understanding of how microbial populations respond to environmental challenges. There are significant benefits to be gained from understanding how microbes adapt in response to climate change and the widespread application of antibiotics, given that microbial populations form intimate associations with humans and sustain all of the world’s ecosystems.Read moreRead less
A novel and theoretically consistent method for correcting systematic errors in earth observation data and earth system model results. For a correct interpretation of satellite-based earth observation data and/or Earth system model results, it is very important that these data are free of systematic errors, commonly referred to as bias. It is well known that both these data sources are prone to a significant bias, which is currently neglected in many environmental impact and prediction studies. ....A novel and theoretically consistent method for correcting systematic errors in earth observation data and earth system model results. For a correct interpretation of satellite-based earth observation data and/or Earth system model results, it is very important that these data are free of systematic errors, commonly referred to as bias. It is well known that both these data sources are prone to a significant bias, which is currently neglected in many environmental impact and prediction studies. This project will present a method to develop models for these biases. A state update technique, the Ensemble Kalman Filter, will be adapted to correctly take into account bias in the merging of the two data sources. The project outcomes will be of high importance for long-term environmental studies, since these strongly rely on physically-based models and remote sensing data.Read moreRead less
An integrated mechanistic model of species' responses to environmental change: from individual responses to range shifts and beyond. To effectively adapt to future environmental change, reliable forecasts are needed of how human alterations to climate and habitat will affect species. This project integrates cutting-edge methods in nutritional, physiological and spatial ecology to develop new tools for predicting and understanding how species will respond to environmental change.
Growing up to be supersonic: bat echolocation origins and mechanics. This project aims to address the unresolved evolutionary origins of bat echolocation.

Interacting with change: inter-specific competition and climate change . The project aims to understand how species will adapt to climate change by examining a largely overlooked process: how competition shapes evolutionary responses. Rising temperatures will fundamentally alter where species live, re-shuffling communities. Yet, how changes in community composition will affect the way current assessments of species vulnerability to climate change is generally unknown. Expected outcomes include i ....Interacting with change: inter-specific competition and climate change . The project aims to understand how species will adapt to climate change by examining a largely overlooked process: how competition shapes evolutionary responses. Rising temperatures will fundamentally alter where species live, re-shuffling communities. Yet, how changes in community composition will affect the way current assessments of species vulnerability to climate change is generally unknown. Expected outcomes include improved species models for predicting responses to climate change through the integration of competitive effects with environmental data. The benefit will be an increased accuracy in predictions of species at risk to climate change which will guide policy and management decisions to protect vulnerable environments better.Read moreRead less
Climate-proofing southeastern Australia's native forests: where, when, and how? Changing environmental conditions and forest fragmentation threaten the ability of native forest species to regenerate or migrate. Using unique long–term datasets and novel statistical analyses, this project will assess future risks to forest regeneration after logging, bushfires, and land abandonment.
