This project will exploit recent advances in ecological and atmospheric modelling with the aim to build improved models of seed dispersal across landscapes to anticipate weed spread. Damaging invasive plants are rapidly transforming landscapes and altering ecosystem function worldwide. The speed and direction of weed spread determines the success or failure of costly containment and control actions, however we lack the ability to adequately predict spread. New models that combine micrometeorological measurements, within-canopy turbulence and topographic variation in wind flows will be designed to better predict where dispersal will occur. In this project, these improved predictions are planned to be combined with decision models to direct the management of invasive species across entire landscapes.Read moreRead less

This project aims to understand the mechanisms promoting shrub expansion in alpine areas and the consequences of a shrub-dominated landscape in terms of shrubs as hydrological mediators and as biodiversity and ecosystem modifiers. Some shrub species trap wind-blown snow, thereby facilitating seedling survival through soil insulation and increases to meltwater. However, if adaptive and plastic responses to climate change allows, shrub expansion will have significant negative impacts on alpine biodiversity and ecosystem function. This project will tease apart the interacting effects of snow, recruitment and adaptation to provide models of shrub increase and determine how shrubs modify alpine ecosystem processes and upper catchment hydrology.Read moreRead less

Summary
In 1999, Seafood Services Australia (SSA) initiated a risk-based approach to assessing and managing hazards. Regarding oysters, two risk assessments were undertaken, one on viruses and one on vibrios. Focusing on the latter hazards, the risks associated with the three main species: V. parahaemolyticus, V. vulnificus and V. cholerae were assessed. It was noted that V. parahaemolyticus (Vp) has recently caused major outbreaks in USA from consumption of oysters due to a “new” pathogenic type O3:K6. ....In 1999, Seafood Services Australia (SSA) initiated a risk-based approach to assessing and managing hazards. Regarding oysters, two risk assessments were undertaken, one on viruses and one on vibrios. Focusing on the latter hazards, the risks associated with the three main species: V. parahaemolyticus, V. vulnificus and V. cholerae were assessed. It was noted that V. parahaemolyticus (Vp) has recently caused major outbreaks in USA from consumption of oysters due to a “new” pathogenic type O3:K6. For Australia, no work on pathogenic Vp in oysters could be found, which introduced a great deal of uncertainty to the assessment. The RA noted that there had been two Vp poisonings in NSW from prawns imported from Indonesia, the clear inference being that pathogenic Vp exists in neighbouring waters.
In March, 2002 the FAO/WHO team will develop a global risk assessment of Vp in oysters. The RA will utilise the US risk model and insert data from the oyster industries of Canada, New Zealand, Australia and Japan. If no Australian data are available on levels of Vp the modellers will make assumptions which may well be disadvantageous to the Australian industry. This could happen if the north American mitigation strategy (rapid icing) to control of Vp is adopted as a prerequisite for export.
Failure to input Australian data into a Codex global risk assessment could have serious consequences for the industry. At best it would lead to protracted negotiation between Australia and Codex. These negotiations would need to be science-based and a research program would need to be funded. It is probable that the scale of this investigation would be at least a log scale larger than the present application.
Among the strategies to mitigate V. parahaemolyticus risk is chilling oysters as early as possible after harvest. In the case of the Canadian industry in British Columbia, the strategy has been used successfully in the summers of 2000 and 2001. This strategy is directly opposed to current summer handling practices by the NSW industry which allows product to remain as warm as 25°C for up to three days.
This project is designed to provide evidence of the occurrence and prevalence of pathogenic and non-pathogenic V. parahaemolyticus in Australian oysters. This knowledge will be invaluable to the NSW industry in particular - in case the FAO/WHO assessment recommends chilling of oysters as a pre-requisite for market access.
Effect of not doing the proposed study
If the work is not done and Codex Committee on Food Hygiene (CCFH) recommend a mitigation strategy of rapid icing, the local industry has a number of choices:
1. Ignore the CCFH recommendation on the grounds that we don’t export large volumes of oysters. The problem with this approach is that Codex has just as much application and force for domestic production as it does in the export arena.
2. Undertake a study to try to show that there is no problem with V. parahaemolyticus from Australian product. This would probably be a larger study than the present one and would be mounted to attempt to gain exemption for Australia. It’s always difficult to unwind global hygiene edicts.
The present project, for a relatively modest investment, effectively places Australian data into a global risk assessment. As such the data will have great force in the modelling phase. xbad Objectives: 1. Obtain total Vibrio spp. and total V. parahaemolyticus counts from oysters from NSW, SA and Tasmania. 2. Determine prevalence of pathogenic V. parahaemolyticus amongst these isolates. 3. Compile and analyse data for potential inclusion in the FAO-WHO global risk assessment of Vibrio parahaemolyticus in oysters. Read moreRead less

This project aims to solve the enduring question about galaxy formation of why galaxies are so inefficient at turning gas into stars. This project will investigate two possible agents for this inefficiency, the pressures exerted by starlight photons and the relativistic cosmic rays produced by supernovae, using a combination of numerical simulations, basic physical analysis, and comparison to observations. The expected outcome will be a greatly improved understanding of the physics of the interaction of radiation and cosmic rays with star-forming interstellar gas. This will help complete the picture of how galaxies like our own came to be, and will provide tools for both future simulations and the interpretation of observations.Read moreRead less
The galactic centre: a laboratory for starburst galaxies. The Milky Way's centre is one of its most captivating regions; here star-formation, and potentially, the region's supermassive black hole, inject enormous amounts of energy and drive a powerful wind of plasma and cosmic rays above the galactic plane. This project will elucidate these processes and help us understand other galactic nuclei.
The Carina Nebula: a massive star factory and the anchor for calibrating extragalactic star formation. Massive stars are vital to the life cycle of a galaxy, providing material and controlling the environment where new stars are made. This project will use the Australia Telescope to map the spectacular Carina Nebula, a hotbed of massive stars, to provide a picture of its stars and gas and a template for understanding star formation in distant galaxies.

There is no text available which describes, the anatomy and histopathologically of the pearl oyster, Pinctada maxima , or the histopathological changes that occur with disease. This lack of published data is compounded by the fact that there are currently only 4 pathologists in Australia with significant experience and knowledge to interpret histology sections from pearl oysters.
The publication of the histopathology photographs collected during project no 94/79 plus other reference material collected by previous researchers will help to overcome this problem.
The ability to be able to recognise what is normal or abnormal is critical in the interpretation of histology sections and hence will affect the quality of diagnostic services that can be provided to the pearling industry.
The publication of this material will also act as a reference book for a range of other investigations into pearl oysters, such as, nutritional, husbandry and biology studies. It will ensure that the material gathered during project no 94/79 will be preserved for the future benefit of the pearling industry. Objectives: 1. Develop a comprehensive histological photographic database of the normal and diseased tissue of the pearl oyster Pinctada maxima . 2. Compile a computerised atlas showing the basic anatomy of Pinctada maxima with explanatory text and labelled photographs of normal and diseased tissue. 3. Publish this data in a book and/or compact disk format. Read moreRead less
