Leader of the pack: social structure and predator management. This project aims to quantify the importance of the individual in behaviour and social structures when managing social predator populations to protect economic and environmental assets. Using dingoes as a model system this project will characterise social structure and behaviour under varying management scenarios.

This project aims to quantify the importance of the individual in behaviour and social structures when managing social predator populations to protect economic and environmental assets. Using dingoes as a model system this project will characterise social structure and behaviour under varying management scenarios. This information will be embedded within models of ecological networks to examine the effects of disrupting dingo packs on biological communities. The project expects to improve understanding of how behaviour and social interactions influence ecological outcomes, improving conservation and management.Read moreRead less
Keystone effects of Australia's top predators: dingoes, devils and biodiversity. This project will study the interactions of Australia's two largest predators, the dingo and Tasmanian devil, with other species. The project will help develop an understanding of the value of these predators in maintaining ecosystem processes and diversity, and guide their management in the future.
The pharmacokinetics of plant secondary metabolites and their effects on feeding in the brushtail possum. Plant secondary metabolites (PSMs) are considered to protect against herbivory, although the mechanisms are not well understood. This project will determine how marsupial folivores avoid toxicity when browsing on Eucalyptus leaf. Blood levels of terpenes, phenols and their metabolites will be measured in the brushtail possum while it feeds on a diet of varying PSM content. We expect to be ab ....The pharmacokinetics of plant secondary metabolites and their effects on feeding in the brushtail possum. Plant secondary metabolites (PSMs) are considered to protect against herbivory, although the mechanisms are not well understood. This project will determine how marsupial folivores avoid toxicity when browsing on Eucalyptus leaf. Blood levels of terpenes, phenols and their metabolites will be measured in the brushtail possum while it feeds on a diet of varying PSM content. We expect to be able to show relationships between the ingestion and blood levels of PSMs and feeding behaviour. This will give a greater understanding of the effect of plant toxins on browsing behaviour, enabling improved foraging models and more effective habitat management.Read moreRead less
Contact Networks, Immunity, and Evolution in Competing Cancer Epidemics. The project aims to evaluate evolutionary interactions between two transmissible cancer epidemics affecting Tasmanian devils and quantify their feedback on infection risk and epidemic behaviour. Using contact tracing and a phylogenetic framework we aim to quantify how tumour lineages evolve with each generation of infection and their effects on susceptibility to infection and disease progression. We expect to reveal the hos ....Contact Networks, Immunity, and Evolution in Competing Cancer Epidemics. The project aims to evaluate evolutionary interactions between two transmissible cancer epidemics affecting Tasmanian devils and quantify their feedback on infection risk and epidemic behaviour. Using contact tracing and a phylogenetic framework we aim to quantify how tumour lineages evolve with each generation of infection and their effects on susceptibility to infection and disease progression. We expect to reveal the host immuno-genetic basis underpinning cancer suppression and the adaptive capacity of populations in response to infectious diseases. This should significantly improve our ability to understand and manage this and other epidemic outbreaks in wildlife, as well as advancing our knowledge in cancer ecology and evolution.Read moreRead less
Using animal-borne cameras to quantify prey field, habitat characteristics and foraging success in a marine top predator. To understand the factors which influence population dynamics, knowledge of habitat use is required. This project will determine the key ecological characteristics of the Australian fur seal habitat, enabling fundamental issues of foraging ecology and wildlife management to be addressed for the first time in a marine mammal.
Conserving wildlife at landscape-scales. The project aims to conserve threatened wildlife at large scales in unfenced landscapes. Using empirical field experiments in Australia and New Zealand, the project will test how suppressing populations of invasive prey – rabbits – could reduce the effect of invasive predators – cats – on native wildlife. Feral cats threaten biodiversity globally, including Australia and New Zealand. Effective control of cats is difficult at large-scales but rabbit contro ....Conserving wildlife at landscape-scales. The project aims to conserve threatened wildlife at large scales in unfenced landscapes. Using empirical field experiments in Australia and New Zealand, the project will test how suppressing populations of invasive prey – rabbits – could reduce the effect of invasive predators – cats – on native wildlife. Feral cats threaten biodiversity globally, including Australia and New Zealand. Effective control of cats is difficult at large-scales but rabbit control is feasible. The project aims to provide a conceptual approach for biodiversity conservation that can be scaled up to mitigate the effects of invasive predators at large scales globally and allow restoration of ecosystems.Read moreRead less
Investigating the genetic basis for heterogeneous susceptibility of Tasmanian devils to a novel infectious cancer. This project will use genetics and modelling to reveal why Tasmanian devils in northwest Tasmania are not dying from facial tumour disease, a new, unusual infectious cancer threatening this iconic carnivore with extinction. This project will predict extinction risk, develop management options, and provide a new template for managing emerging wildlife diseases.
