Invasion biology: understanding the mechanisms of naiveté towards alien species. Naiveté in local wildlife is central to why alien species are so damaging, yet it is typically viewed as a simple lack of recognition of novel enemies. This project tests for multiple levels of naiveté in Australia’s mammals to demonstrate its many complex forms. It will use field and lab experiments and formal meta-analysis to unravel the three main forms of naiveté, to reveal their role in predator:prey and compet ....Invasion biology: understanding the mechanisms of naiveté towards alien species. Naiveté in local wildlife is central to why alien species are so damaging, yet it is typically viewed as a simple lack of recognition of novel enemies. This project tests for multiple levels of naiveté in Australia’s mammals to demonstrate its many complex forms. It will use field and lab experiments and formal meta-analysis to unravel the three main forms of naiveté, to reveal their role in predator:prey and competitive interactions, and to understand how native and alien mammals might overcome their initial naiveté to novel enemies. These results will identify to ecologists and land managers the complex nature of naiveté, and how it ultimately defines the nature of interactions between aliens and natives.Read moreRead less
Satellite tracking of health threats from grass pollen exposure. This project aims to discover why pollen exposure has increased since the 1960s. Grass pollens are the main environmental allergen source in Australia and the primary cause of allergic diseases. This project will investigate the ecological causes of changing pollen allergen exposures through integrating 40 years of satellite data, field phenology cameras, and pollen traps that track grass pollen sources, their evolution and impact ....Satellite tracking of health threats from grass pollen exposure. This project aims to discover why pollen exposure has increased since the 1960s. Grass pollens are the main environmental allergen source in Australia and the primary cause of allergic diseases. This project will investigate the ecological causes of changing pollen allergen exposures through integrating 40 years of satellite data, field phenology cameras, and pollen traps that track grass pollen sources, their evolution and impact areas. The outcomes are expected to advance knowledge of environmental drivers and enable more accurate pollen forecasts that alleviate the medical and socioeconomic burden of allergic diseases, estimated to cost 30 billion dollars.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
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.
Does coevolution or ecological context determine predator-prey coexistence? This project aims to deliver the first robust evaluation of the evolutionary and ecological conditions that combine to enable introduced predators to drive extinctions of native mammals. The project will bring together disciplines of invasion biology and trophic cascades to model predator-prey systems in the presence and absence of apex predators. This globally unique study will provide an informed and transparent toolse ....Does coevolution or ecological context determine predator-prey coexistence? This project aims to deliver the first robust evaluation of the evolutionary and ecological conditions that combine to enable introduced predators to drive extinctions of native mammals. The project will bring together disciplines of invasion biology and trophic cascades to model predator-prey systems in the presence and absence of apex predators. This globally unique study will provide an informed and transparent toolset for preventing decline of threatened species and will enhance Australian conservation policy by untangling contrasting perspectives of introduced predators and the conditions that lead to native species extinction.Read moreRead less
Call Out and Listen In: A New Way to Detect and Control Invasive Species. This project aims to use novel acoustic techniques to detect and capture invasive frog species to protect native species. Invasive frogs are an under-appreciated but serious ecological problem worldwide, because they are voracious predators and are often toxic to native species. Male frogs call to attract mates, and answer calls they hear. Using new acoustic technologies, these behaviours can be exploited to detect species ....Call Out and Listen In: A New Way to Detect and Control Invasive Species. This project aims to use novel acoustic techniques to detect and capture invasive frog species to protect native species. Invasive frogs are an under-appreciated but serious ecological problem worldwide, because they are voracious predators and are often toxic to native species. Male frogs call to attract mates, and answer calls they hear. Using new acoustic technologies, these behaviours can be exploited to detect species and attract gravid females for removal. This project aims to combine an early warning system (electronic listening) and trap (calling and catching), which can be customised to any invasive frog, and use it to detect and remove cane toads, especially in low density populations.Read moreRead less
Either side of the Big Wet: the future resilience of south-eastern Australia's biota. Australia must develop strategies for managing its biodiversity under climate changes expected to occur under projected Intergovernmental Panel on Climate Change (IPCC) emission scenarios. The project will furnish comprehensive data on the response of plants and animals to the break in the Big Dry (1997-2009) in 2010-11 and evaluate how predict biotic components will cope with future climates.

Invasive species have detrimental effects on human health, the economy and native biodiversity. This study will address a major gap in our scientific understanding of invasions by undertaking the first large-scale examination of the role of interactions between species in determining the dynamics and outcomes of biological invasions. The project will integrate data, across four continents, on dispersal, demography, breeding and behavioural interactions into one framework to create a cutting-edge model of invasion dynamics, using the highly invasive common myna as a model system. This novel approach will significantly advance theoretical developments in invasion biology and will inform pest management and threat mitigation efforts globally.Read moreRead less
