Understanding the ecological effects of genetic diversity: causes, consequences and relative importance. This project will examine the effect of genetic diversity on key demographic parameters (for example, population growth rates) for organisms from three groups, including a commercially important oyster. This project provides valuable information that can be used by managers of wild and cultivated populations to minimise impacts of human activities and maximise yields.

Summary
Impacts on wildlife populations of infection by multiple, interacting pathogens and the implications for disease management. Simultaneous infection by multiple pathogens is common in nature and interactions among pathogens within a host can profoundly alter the susceptibility of hosts to infection, disease severity and the probability of further transmission. This project aims to understand the consequences of these interactions on both wildlife populations and the communities of pathogens that ....Impacts on wildlife populations of infection by multiple, interacting pathogens and the implications for disease management. Simultaneous infection by multiple pathogens is common in nature and interactions among pathogens within a host can profoundly alter the susceptibility of hosts to infection, disease severity and the probability of further transmission. This project aims to understand the consequences of these interactions on both wildlife populations and the communities of pathogens that infect them. This knowledge will improve our ability to manage disease in wild populations, which is critical for protecting people, livestock and species of conservation concern from emerging disease threats. The application of these findings to koalas will enhance the efficiency and cost-effectiveness of disease management and improve long term population persistence.Read moreRead less
Population fluctuations: models, mechanisms and management. Changes in plant populations lead to extinctions and invasions in Australia and globally. The project will determine the drivers of plant population change and provide new tools to enable better population management.
Determining how plant populations will respond to climate change. It is widely predicted that global climate change will result in extinctions, invasions and disruption of the ecosystem services plants provide. In order to manage or adapt to these consequences of changing climate we need accurate forecasts of where suitable conditions for sustainable plant populations will occur. This project will enable better forecasts of where and how fast plant populations will expand or contract in response ....Determining how plant populations will respond to climate change. It is widely predicted that global climate change will result in extinctions, invasions and disruption of the ecosystem services plants provide. In order to manage or adapt to these consequences of changing climate we need accurate forecasts of where suitable conditions for sustainable plant populations will occur. This project will enable better forecasts of where and how fast plant populations will expand or contract in response to climate change. New population modelling methods which integrate plant survival, growth and reproduction along environmental gradients, together with field studies at unprecedented national and international scales, will enable better forecasts of future locations for plant dependent industries and environmental services.Read moreRead less
A novel modelling approach for understanding wildlife disease dynamics. This project aims to develop a novel framework for field wildlife disease systems, applied to chytrid fungal infection of an endangered frog species as a case study. The project expects to develop models able to be applied to many disease systems, improve understanding of host resistance and tolerance to infection, and improve capacity for mitigation of emerging infectious diseases.

This project aims to address the damage caused by invasive foxes by applying new methods of protection for threatened species. This project expects to generate new knowledge in the areas of conservation biology and invasive species management by comparing the effectiveness of fox control strategies for improving the population viability of declining freshwater turtles. Expected outcomes of this project include a community-based conservation model that prevents turtle extinctions in south-eastern Australia at considerable cost savings. Significant benefits include improved management of the impacts of invasive species, and restoration of ecosystem services provided by the scavenging role of freshwater turtles for maintaining water quality.Read moreRead less

Summary
Understanding infection tolerance to improve management of wildlife disease. This project aims to investigate tolerance (the ability to limit the detrimental effects of infection) as a key animal defence strategy against disease. It focuses on diseases in natural systems, using the devastating amphibian fungal skin disease, chytridiomycosis, as a model. Expected outcomes include improved understanding of the relative importance of tolerance and resistance, and insight into the key immune and phy ....Understanding infection tolerance to improve management of wildlife disease. This project aims to investigate tolerance (the ability to limit the detrimental effects of infection) as a key animal defence strategy against disease. It focuses on diseases in natural systems, using the devastating amphibian fungal skin disease, chytridiomycosis, as a model. Expected outcomes include improved understanding of the relative importance of tolerance and resistance, and insight into the key immune and physiologic mechanisms underlying variations in tolerance. Anticipated benefits include improved strategies for mitigating infectious wildlife diseases via identifying targets for therapeutic interventions, ecological management and assisted-evolution strategies. This project should also benefit amphibian conservation globally.Read moreRead less
Exotic and native plant coexistence in novel communities. The development of novel communities has become an inevitable outcome of global change. Despite this, we have a poor understanding of the mechanisms driving their assembly. Here, experimental and modelling approaches will be used to identify how competition among native and exotic plant species change across key environmental gradients, leading to: resilient native communities; stable novel communities - mixes of native and exotic species ....Exotic and native plant coexistence in novel communities. The development of novel communities has become an inevitable outcome of global change. Despite this, we have a poor understanding of the mechanisms driving their assembly. Here, experimental and modelling approaches will be used to identify how competition among native and exotic plant species change across key environmental gradients, leading to: resilient native communities; stable novel communities - mixes of native and exotic species; or, degraded communities dominated by exotic species. The annual plant communities of Western Australia's (WA) York Gum woodlands will be used as a model system. Outcomes will improve management of WA wildflower communities and provide a framework for predicting novel community formation worldwide.Read moreRead less
How complex species interactions mediate plant community diversity. This project aims to manage and protect biodiversity under global change by adding biological realism to mechanistic diversity models. Species interactions are central to understanding biodiversity at local to regional scales. Most diversity models assume that direct competition captures all salient details of species interactions, while more complex species interactions are unimportant. This unsupported, pervasive assumption ha ....How complex species interactions mediate plant community diversity. This project aims to manage and protect biodiversity under global change by adding biological realism to mechanistic diversity models. Species interactions are central to understanding biodiversity at local to regional scales. Most diversity models assume that direct competition captures all salient details of species interactions, while more complex species interactions are unimportant. This unsupported, pervasive assumption has major consequences for how diversity is predicted and explained. This study will combine field experiments on plant species’ responses to climate and land use changes with a modelling framework. Expected outcomes include improving the ability to manage invasive species and to protect biodiversity under conditions of global environmental change.Read moreRead less
