Summary
Do novel diets reshape wildlife microbiomes and resilience to stressors? This project aims to investigate how bacteria can assist wildlife in adapting to the accelerating threat of environmental change. Using an innovative, interdisciplinary approach this project expects to identify interactions between environmental change and the diet, microbial communities and stress resilience of wildlife, using the threatened Grey-headed flying fox as a model system. Expected outcomes include detailed under ....Do novel diets reshape wildlife microbiomes and resilience to stressors? This project aims to investigate how bacteria can assist wildlife in adapting to the accelerating threat of environmental change. Using an innovative, interdisciplinary approach this project expects to identify interactions between environmental change and the diet, microbial communities and stress resilience of wildlife, using the threatened Grey-headed flying fox as a model system. Expected outcomes include detailed understanding of the role of microbial communities in shaping wildlife adaptations and development of ecological interventions to enhance wildlife resilience in Australia and globally. Such outcomes may reveal opportunities for management strategies that safeguard threatened species and reduce human-wildlife conflicts.Read moreRead less
Stress, virulence and bacterial disease in temperate seaweeds: the rise of the microbes. Climate change is predicted to increase the spread and virulence of pathogens, and decrease the resistance to disease via temperature stress on the hosts. Combined with other human impacts (higher nutrients, pollution), we may be facing a major rise in the effect of disease on natural communities. However, these effects are largely unstudied. We will investigate the impact of marine pathogens on kelps and ....Stress, virulence and bacterial disease in temperate seaweeds: the rise of the microbes. Climate change is predicted to increase the spread and virulence of pathogens, and decrease the resistance to disease via temperature stress on the hosts. Combined with other human impacts (higher nutrients, pollution), we may be facing a major rise in the effect of disease on natural communities. However, these effects are largely unstudied. We will investigate the impact of marine pathogens on kelps and other seaweeds when they are stressed by temperature, elevated nutrients or other anthropogenic stressors. Kelp are the 'trees of the oceans', the organisms responsible for creating much of the habitat that fishes and other organisms live in. The loss of kelp forests due to disease would radically change these environments.Read moreRead less
Dispersal and colonisation in eukaryotes and prokaryotes. The problem of pest or disease organisms for humanity is fundamentally a problem of unwanted colonisation. For example, colonisation of the surfaces of human tissues by bacterial biofilms is responsible for up to 70% of bacterial infections; colonisation of the surfaces of boat hulls by marine organisms costs the marine shipping industry > $5 billion per year. This proposal will generate fundamental information on the ability of both bac ....Dispersal and colonisation in eukaryotes and prokaryotes.

For example, colonisation of the surfaces of human tissues by bacterial biofilms is responsible for up to 70% of bacterial infections; colonisation of the surfaces of boat hulls by marine organisms costs the marine shipping industry > $5 billion per year. This proposal will generate fundamental information on the ability of both bacteria and higher organisms to disperse and colonise surfaces, allowing for the development of novel technologies for the prevention of unwanted colonisation of surfaces.

Delivering defences: using fungi to enhance plant resistance to herbivory. This project will identify how the diversity of beneficial fungi in the soil is affected by agricultural management, and will reveal how these fungi govern the ability of plants to defend themselves from insect herbivores. Through innovative field surveys and experimentation, this project will generate new knowledge in the key areas of soil ecology and plant defence. This will allow us to exploit these soil fungi to enhan ....Delivering defences: using fungi to enhance plant resistance to herbivory. This project will identify how the diversity of beneficial fungi in the soil is affected by agricultural management, and will reveal how these fungi govern the ability of plants to defend themselves from insect herbivores. Through innovative field surveys and experimentation, this project will generate new knowledge in the key areas of soil ecology and plant defence. This will allow us to exploit these soil fungi to enhance crop protection while simultaneously conserving soil ecosystems. Effectively boosting plant defence in this way will reduce reliance on ecologically damaging pesticides, promote soil biodiversity, and ensure the sustainability of crop production into the future.
