Molecular biosecurity: Genomic databanks for managing new pest invasions. This project aims to develop a set of genomics-based approaches for analysing new pest invasions. By producing and analysing genomic databanks for four insect pest species, including three that have recently invaded Australia, this project expects to identify invasion origins and to track new pest incursions within Australia.

This project aims to develop a set of genomics-based approaches for analysing new pest invasions. By producing and analysing genomic databanks for four insect pest species, including three that have recently invaded Australia, this project expects to identify invasion origins and to track new pest incursions within Australia. The project should also provide insights into pest ecology, including movement rates and population change over time. This information can enable more efficient deployment of biosecurity resources and pave the way for genomics to be used pre-emptively to stop new invasions. This can help make genomics a go-to response to new pest invasions and position Australia at the forefront of genomics-based pest biosecurity.Read moreRead less

Summary
Evolution of chemical warfare in invasive plants. The project aims to test when, where and how exotic plant populations become invasive through the rapid evolution of chemical compounds that inhibit native plant species. Using an innovative quantitative genetics framework, the intended outcome is to determine how the chemicals are selected, and whether there is sufficient heritable variation for the chemicals to evolve across heterogeneous landscapes characteristic of introduced ranges. The proj ....Evolution of chemical warfare in invasive plants. The project aims to test when, where and how exotic plant populations become invasive through the rapid evolution of chemical compounds that inhibit native plant species. Using an innovative quantitative genetics framework, the intended outcome is to determine how the chemicals are selected, and whether there is sufficient heritable variation for the chemicals to evolve across heterogeneous landscapes characteristic of introduced ranges. The project will deliver key insights into the ecological and genetic mechanisms of adaptive evolution in invasive species, and predict evolutionary dynamics of biological invasions that inform their effective management. The project’s expected outcomes will be useful to policy makers, weed managers and farming communities.Read moreRead less

Summary
Genetic and epigenetic drivers of the Australian cane toad invasion. Although invasive species are a massive threat to biodiversity, and costly to society, we still do not understand the evolutionary processes that shape invasions. Invasive populations often show rapid evolutionary change in novel environments but attempts to identify the underlying genetic mechanisms have been largely unsuccessful. This project aims to explore an innovative and untested alternative possibility: that invader evo ....Genetic and epigenetic drivers of the Australian cane toad invasion. Although invasive species are a massive threat to biodiversity, and costly to society, we still do not understand the evolutionary processes that shape invasions. Invasive populations often show rapid evolutionary change in novel environments but attempts to identify the underlying genetic mechanisms have been largely unsuccessful. This project aims to explore an innovative and untested alternative possibility: that invader evolution is primarily driven by epigenetic change. Using an iconic Australian invasive species, the cane toad, the project aims to quantify genetic and epigenetic change across the invasion and use manipulative experiments to determine the influence of epigenetic change on the evolution of phenotypic traits important to invasion.Read moreRead less

Summary
Protecting prey from predators using sensory tactics. This project aims to develop new approaches to prevent the extinction of threatened native species from invasive predators, such as rats, pigs, cats and foxes. Many native species are hard to see but vulnerable to being found by predators with powerful senses of smell and hearing.

This project aims to develop new approaches to prevent the extinction of threatened native species from invasive predators, such as rats, pigs, cats and foxes. Many native species are hard to see but vulnerable to being found by predators with powerful senses of smell and hearing. By harnessing the sensory cues of prey that predators use when hunting, this project expects to discover olfactory and auditory techniques that prevent predators finding threatened species. In doing so, the project intends to provide new perspectives on how animals find food using multiple senses, and lead the recovery of threatened species in areas where predators remain within Australia and globally.

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.

. 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

Summary
Rogue Killers; implications for predator-prey theory. The project intends to extend predator–prey theory by developing a predation–risk model that incorporates individual differences in predation rate. Predation by introduced predators is the most significant cause of fauna decline in Australia and New Zealand.

The project intends to extend predator–prey theory by developing a predation–risk model that incorporates individual differences in predation rate. Predation by introduced predators is the most significant cause of fauna decline in Australia and New Zealand. Current predator–prey theory is based on population-level processes and predator control used to protect threatened wildlife assumes that the removal of each predator is equally important. However, evidence suggests that in many cases only a few individual predators are responsible for population decline. If the physical or behavioural characteristics of successful individual predators can be identified then predator profiling can be used to control problem animals and improve the efficacy of feral animal control programs.Read moreRead less

This project aims to investigate the functional role of native and introduced herbivores in forest ecosystems using a powerful, highly replicated, herbivore exclosure experiment. This project expects to create new knowledge of the effects of mammalian herbivores, particularly kangaroos and invasive deer, on forest plants, soils and productivity. Expected outcomes include fundamental insights into above and belowground interactions in forests, and an enhanced capacity to predict effects of changing herbivore populations across environmental gradients, and following bushfire. This should produce significant benefits for forest management in Australia, allowing informed, targeted, and pre-emptive management of invasive herbivore populations.Read moreRead less

Drawing on emerging theory and a tight integration of modelling and experiments in a model microbial system, this project aims to investigate the impact of modified nutrient regimes on the structure and stability of ecological communities. This project expects to generate new knowledge at the forefront of research into diversity maintenance, ecosystem functioning and higher-order interactions. The outcomes should provide a deep mechanistic understanding of microbial community dynamics, with applications from animal health to environmental flows and insect pest management.Read moreRead less
