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

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
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.
Messing with their minds: using deception to improve pest management. This project aims to develop new approaches to improve wildlife management by showing how deceit and misinformation can alter decision-making in pest animals. Using wild house mice as a model, it will test new theory on how animals decide whether or not to interact with wildlife control devices, like traps and baits, which is critical to all pest control efforts. The expected outcomes include new pest control tools that make s ....Messing with their minds: using deception to improve pest management. This project aims to develop new approaches to improve wildlife management by showing how deceit and misinformation can alter decision-making in pest animals. Using wild house mice as a model, it will test new theory on how animals decide whether or not to interact with wildlife control devices, like traps and baits, which is critical to all pest control efforts. The expected outcomes include new pest control tools that make strategic use of misinformation to alter decision making, to reduce a pest's ability to damage important agricultural crops such as wheat, boost the attraction of lures to traps, and improve bait uptake. These outcomes should provide significant new options for vertebrate pest control in Australia and globally.Read moreRead less

Managing the effects of disturbance on coral reef biodiversity: modelling starfish outbreaks in a changing world
. Coral communities of the Great Barrier Reef are facing multiple disturbances, in particular the coral-eating crown-of-thorns starfish Acanthaster planci (A. planci) that can occur as large-scale outbreaks. This project aims to provide innovative guidance in support of the management of A. planci, based on a metapopulation modelling framework broadly applicable to the control of mar ....Managing the effects of disturbance on coral reef biodiversity: modelling starfish outbreaks in a changing world
. Coral communities of the Great Barrier Reef are facing multiple disturbances, in particular the coral-eating crown-of-thorns starfish Acanthaster planci (A. planci) that can occur as large-scale outbreaks. This project aims to provide innovative guidance in support of the management of A. planci, based on a metapopulation modelling framework broadly applicable to the control of marine pests. Expected outcomes include the identification of the environmental triggers of A. planci outbreaks; the identification of target reefs and critical thresholds of management intervention needed to limit the impact of A. planci under different climate and land use scenarios; and future forecasts of coral and fish biodiversity under these scenarios.Read moreRead less
An integrated tool for informing pest management: modelling range shifts for an invasive vertebrate in response to climate change. Invasive species and climate contribute directly to loss of biodiversity and economic productivity. This research project focuses on providing user-orientated tools that enable a strategic approach to European rabbit management and vertebrate pest control in Australia in response to anticipated climate and land-use change.
Understanding population growth time lags in invasive species. This project will use data collected from wild animals, landholder surveys, and computer simulation models to understand why invasive chital deer (Axis axis) are suddenly increasing in number after many years of slow population growth. By combining multiple empirical datasets and developing new modelling techniques, we will generate a new method for understanding population trends in introduced species. The results of this study will ....Understanding population growth time lags in invasive species.

By combining multiple empirical datasets and developing new modelling techniques, we will generate a new method for understanding population trends in introduced species. The results of this study will allow Queensland Department of Agriculture and Fisheries and others to better predict invasive species growth rates, which will allow for better, and more cost effective control methods.

Predicting the causes and consequences of plant invasions. Invasive plants are one of the most costly and significant environmental threats in Australia. To deal with this threat we need to understand how and why certain plant species are able to invade into and dominate native communities. The aim of this project is to uncover the rules that govern this environmental threat. The project endeavours to use theory to predict the outcomes that would be observed given different underlying rules, and ....Predicting the causes and consequences of plant invasions. Invasive plants are one of the most costly and significant environmental threats in Australia. To deal with this threat we need to understand how and why certain plant species are able to invade into and dominate native communities. The aim of this project is to uncover the rules that govern this environmental threat. The project endeavours to use theory to predict the outcomes that would be observed given different underlying rules, and then test these predictions with field experiments. By uncovering the rules that govern invasions, this project could provide fundamental knowledge to assist in managing the environmental threat posed by new and emerging weeds.Read moreRead less
