This project aims to investigate whether Australia’s ‘shared responsibility’ approach to biosecurity is capable of facing the growing threat from exotic pests and diseases. Through the analysis of policy documents and the use of semi-structured interviews, this project intends to contribute to a deeper understanding of the inter- and intra-organisational characteristics that influence implementation of biosecurity. Expected outcomes include crucial insights into the capacity of a shared responsibility approach to protect agri-food production against biological threats, and the forms of institutional change that may be needed to enhance responsiveness to those threats. This in turn will benefit Australia's biosecurity system.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.
Impact of Metal - Reactive Oxygen Species (ROS) Interactions on Growth and Toxicity of Ichthyotoxic Algae in Australian Coastal Waters. Toxic algal blooms in estuarine and coastal waters can have devastating economic and ecological impacts but remarkably little is known about the factors that control either organism growth or toxin severity. Recent studies suggest that the interplay between delivery of the nutrient trace metals iron and copper and the method via which the organism acts to assimi ....Impact of Metal - Reactive Oxygen Species (ROS) Interactions on Growth and Toxicity of Ichthyotoxic Algae in Australian Coastal Waters. Toxic algal blooms in estuarine and coastal waters can have devastating economic and ecological impacts but remarkably little is known about the factors that control either organism growth or toxin severity. Recent studies suggest that the interplay between delivery of the nutrient trace metals iron and copper and the method via which the organism acts to assimilate these metals is critical to the generation and aggressiveness of the toxins produced. These processes will be investigated in this study and conceptual and mathematical models will be developed which will assist in assessing management options for estuarine and coastal environments.Read moreRead less
Prediction of radiated noise from marine propellers. Underwater noise radiated from marine vessels is a significant problem for research, fishing and military vessels, and is a major source of pollution in the marine environment. The major source contributing to underwater noise is due to the propeller. This work will develop numerical models with experimental validation that can accurately predict the sources of noise generated by marine propellers and acoustic signatures of marine vessels due ....Prediction of radiated noise from marine propellers. Underwater noise radiated from marine vessels is a significant problem for research, fishing and military vessels, and is a major source of pollution in the marine environment. The major source contributing to underwater noise is due to the propeller. This work will develop numerical models with experimental validation that can accurately predict the sources of noise generated by marine propellers and acoustic signatures of marine vessels due to propeller motion. This work has great significance for Australia’s construction and military maritime industries. The technologies developed in this project are also applicable to rotors in other industries such as in aircraft, helicopters and wind turbines.Read moreRead less
Mapping Antarctic climate change in space and time using mosses as biological proxies. This project will use polar mosses as sentinels for climate change to determine the extent to which change is already affecting Antarctica and enable development of more robust global climate models. Novel remote sensing methods will be developed to identify biodiversity most at risk from climate change thus maintaining Antarctic treaty obligations.
The Role of Naturalism in Ontology and Scientific Methodology. Naturalism is the philosophical doctrine perhaps best described as a respect for the methods of the natural sciences. Although most contemporary philosophers would describe themselves as naturalists, exactly how this important doctrine is spelled out is a matter of much controversy. What is more, many substantial issues in both philosophy of science and in metaphysics depend crucially on how we understand naturalism. This project ....The Role of Naturalism in Ontology and Scientific Methodology. Naturalism is the philosophical doctrine perhaps best described as a respect for the methods of the natural sciences. Although most contemporary philosophers would describe themselves as naturalists, exactly how this important doctrine is spelled out is a matter of much controversy. What is more, many substantial issues in both philosophy of science and in metaphysics depend crucially on how we understand naturalism. This project will investigate the various conceptions of naturalism, looking at both their motivations and their implications for philosophy and scientific and mathematical methodology.Read moreRead less
AirLIFT – an airborne active chlorophyll fluorescence sensing system for assessment of photosynthetic activity in plant canopies. Assessment of plant health and productivity is vital to ensure future food security of the global population under a changing climate. Chlorophyll fluorescence (CF), a signal emitted by green plants, can reveal this information.

Assessment of plant health and productivity is vital to ensure future food security of the global population under a changing climate. Chlorophyll fluorescence (CF), a signal emitted by green plants, can reveal this information. Although CF has revolutionised photosynthetic research, current measurements are limited to individual plants. Remote sensing of canopy CF is required for efficient management of agricultural crops, forests, and natural ecosystems and is crucial for accurate estimation of plant carbon assimilation and production. This project will deliver remote sensing technology to bridge the gap between leaf and canopy productivity and pave the way for understanding both artificial and solar induced canopy CF measured from space.Read moreRead less
High resolution health assessment of Antarctic plants as climate changes. Declines in terrestrial ecosystem health as a result of a drying climate have been observed in some areas of East Antarctica. This project aims to determine if such changes are widespread. Since mosses, the dominant plants of Antarctica, preserve a record of past climate down their shoots they can be used as surrogates to study how both ecosystems and climate are changing at remote polar sites. Outcomes will include improv ....High resolution health assessment of Antarctic plants as climate changes. Declines in terrestrial ecosystem health as a result of a drying climate have been observed in some areas of East Antarctica. This project aims to determine if such changes are widespread. Since mosses, the dominant plants of Antarctica, preserve a record of past climate down their shoots they can be used as surrogates to study how both ecosystems and climate are changing at remote polar sites. Outcomes will include improved climate data for Antarctica, enabling more robust analysis of regional climate change, and development of ultrahigh-resolution techniques capable of non-destructively monitoring Antarctic ecosystem health. This research will advance ecosystem science and inform best practice in management of Antarctic biodiversity.Read moreRead less

This project will examine the mechanisms underpinning the high productivity in Antarctic coastal polynyas, which are ice-free oases within the sea ice supporting abundant marine life. The study expects to generate essential new biochemical and biological observations using autonomous platforms to understand phytoplankton dynamics in these inaccessible habitats along Australia’s Antarctic Territory. Expected outcomes include novel insight into the role of iron supply from melting glaciers in supporting marine production. This should reduce the high uncertainty in prognoses for polynya activity under anthropogenic climate change, and support Australia’s international leadership in conservation and management of important Antarctic ecosystems.Read moreRead less
