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
How does your garden grow? Scaling functional traits to whole-plant growth. Understanding how the traits of leaves and stems influence plant growth is important because plant growth drives emergent ecosystem properties such as rates of water use and carbon and nitrogen cycling. The project will build a new understanding of trait-growth relationships, focusing on species from four Australian forest types.
Testing the importance of large-scale climate factors to plant community assembly following land-use change. This project will examine the native plant species and functional diversity of Australia's rain forest communities to create a predictive framework of how plant communities recover following deforestation. Such a framework is key to focusing conservation efforts in degraded and multi-use landscapes.

Summary
Is plant organisation the fountain of eternal youth? The decline in performance at advanced ages, senescence, affects life quality, lifespan and productivity. It is believed that this phenomenon is universal, including all species from microbes to humans. Yet, some plants do not exhibit senescence. This project will identify the mechanisms that enable plants to escape senescence. Using a unique global demographic database, the project will determine whether, how and when senescence has evolved a ....Is plant organisation the fountain of eternal youth? The decline in performance at advanced ages, senescence, affects life quality, lifespan and productivity. It is believed that this phenomenon is universal, including all species from microbes to humans. Yet, some plants do not exhibit senescence. This project will identify the mechanisms that enable plants to escape senescence. Using a unique global demographic database, the project will determine whether, how and when senescence has evolved across 850 plant species. It will also experimentally test how drought, nutrients and resprouting affect senescence in two mallee Eucalyptus species in the Simpson Desert. This research will provide new insights into the evolution of senescence and will elucidate how some plants escape a supposedly unavoidable fate.Read moreRead less
