This project will better enable Australia to meet its international treaty obligations on migratory birds and provide much needed data on patterns of migratory connectivity in northern Australia. These data are critical for the conservation and management of bird species that spend part of their life-cycle outside Australia. The outputs of the project will be used to assist decision makers with policy and management decisions relevant to (1) targeted surveillance for exotic and emergent diseases of relevance to Australia and (2) the conservation and management of bird populations in Northern Australia.Read moreRead less
Establishment of the Australian Cane Toad Genome Program. The Cane Toad is one of Australia's greatest environmental menaces, and is in the top 100 of the "World's Worst invader species". Over a billion toads infest Northern Australia, and they will soon invade WA and move further into NSW. Their poisons and voracious appetite could make many native mammals, birds and reptiles extinct. The only possibility to eradicate the Toad is by biological control, but there is no known control agent. We wi ....Establishment of the Australian Cane Toad Genome Program. The Cane Toad is one of Australia's greatest environmental menaces, and is in the top 100 of the "World's Worst invader species". Over a billion toads infest Northern Australia, and they will soon invade WA and move further into NSW. Their poisons and voracious appetite could make many native mammals, birds and reptiles extinct. The only possibility to eradicate the Toad is by biological control, but there is no known control agent. We will identify the 'Toad's Achilles' heel' against which control agents can be developed. We can do this by identifying every Toad gene. This project forms the first step to this goal by establishing the Australian Cane Toad Genome Program. Toad control will help preserve Australia's unique natural heritage.Read moreRead less
Insect age: an ecological genomics approach to understanding host-parasite interactions. The importance of insect age (or the age structure of a population of insects) in understanding relationships between insects and their abiotic and biotic environment has been stressed in many theoretical studies but seldom directly tested. This is because few tools exist that can accurately measure the age of a wild-caught insect with any accuracy. In this proposal we plan to use a genomics approach to deve ....Insect age: an ecological genomics approach to understanding host-parasite interactions. The importance of insect age (or the age structure of a population of insects) in understanding relationships between insects and their abiotic and biotic environment has been stressed in many theoretical studies but seldom directly tested. This is because few tools exist that can accurately measure the age of a wild-caught insect with any accuracy. In this proposal we plan to use a genomics approach to develop tools that can be used to efficiently determine the age of an insect and then apply these tools to better understand the relationship between insect age and the ability of an insect to transmit pathogens to humans, livestock or plants. These tools will also have future applicability in developing new approaches to control insect transmitted disease as well as provide methodology to determine the effectiveness of current control programs that seek to kill pest insect populations of agricultural or public health significance.Read moreRead less
Fruit fly pests in northwestern Australia: invasion, hybridisation or evolution? In northwestern Australia, recent events suggest that a new and serious fruit fly pest is now present, wher previously none existed. Due to difficulties in accurate identification, we do not know whether these new pest fruit flies are endemic fruit flies that have changed their behaviour, invasions of Queensland fruit fly, or hybrids between them. This project will use DNA microsatellites to distinguish between th ....Fruit fly pests in northwestern Australia: invasion, hybridisation or evolution? In northwestern Australia, recent events suggest that a new and serious fruit fly pest is now present, wher previously none existed. Due to difficulties in accurate identification, we do not know whether these new pest fruit flies are endemic fruit flies that have changed their behaviour, invasions of Queensland fruit fly, or hybrids between them. This project will use DNA microsatellites to distinguish between these possibilities. It will also establish whether the different species involved are actually different species, or should be regarded merely as different races. Such distinctions are important both scientifically and for export quarantine purposes.Read moreRead less
Real-time phylogenetics for food-borne outbreak surveillance. The project aims to introduce, for the first time, real-time evolutionary analysis of agricultural pathogens so that outbreaks affecting crops and the food supply can be managed precisely and rapidly. An expert team will implement a large-scale data analytics framework in user-friendly software that integrates Australian infectious disease genomics data with global data. Underpinning this work are new theory and algorithms that apply ....Real-time phylogenetics for food-borne outbreak surveillance. The project aims to introduce, for the first time, real-time evolutionary analysis of agricultural pathogens so that outbreaks affecting crops and the food supply can be managed precisely and rapidly. An expert team will implement a large-scale data analytics framework in user-friendly software that integrates Australian infectious disease genomics data with global data. Underpinning this work are new theory and algorithms that apply Sequential Monte Carlo to update phylogenetic analyses continuously as new data arrives. Expected outcomes include new knowledge of statistical algorithms for evolutionary analysis, relevant to biological disciplines beyond infectious disease; and enhanced capacity for infectious disease analysis.

Infectious disease causes major economic loss to the aquaculture industry, highlighting the need for effective vaccination strategies. While oral or immersion vaccination represents the most cost effective means of protecting fish against infectious disease there are problems associated with inducing an effective immune response in fish that will assist our industry partner (Novartis Animal Vaccines Ltd) to develop improved fish vaccines. The project will provide postgraduate training in the area of fish immunology that is vital to the developing Australian aquaculture industry.Read moreRead less
Identification of Traits and Function by Genomic Matching. Differences between individuals are largely inherited and therefore encoded within the DNA. The challenge is to develop practical means of detecting these differences irrespective of whether they are observable as a phenotype.
Here we focus on livestock. For example, most Australian cattle are horned rather than polled. The inheritance is relatively simple but there is still no DNA test to detect the recessive horning gene.

Here we focus on livestock. For example, most Australian cattle are horned rather than polled. The inheritance is relatively simple but there is still no DNA test to detect the recessive horning gene.
The genomic matching technique is an in-house patented procedure for identifying such DNA differences. If successful, our test will assist industry to eliminate horning and thereby painful dehorning whilst reducing damage to workers and product.

New approaches for screening cereal germplasm for enhanced microbial pathogen resistance and desirable grain texture. The trait of grain hardness (texture) is of significance to the Australian infrastructure, as exports of hard wheat contribute over 5 billion dollars per year on average to the national economy and hard wheats are also important for domestic usage. The genes responsible for grain texture also impart resistance to bacterial and fungal pathogens which can cause extensive damage. ....New approaches for screening cereal germplasm for enhanced microbial pathogen resistance and desirable grain texture. The trait of grain hardness (texture) is of significance to the Australian infrastructure, as exports of hard wheat contribute over 5 billion dollars per year on average to the national economy and hard wheats are also important for domestic usage. The genes responsible for grain texture also impart resistance to bacterial and fungal pathogens which can cause extensive damage. However, the Australian gene pool has very limited genetic diversity in grain textures and thus possibly in pathogen resistance. The project will work out the science behind these two traits and identify lines with new variants of textures and pathogen resistances, thus greatly benefiting the national infrastructure and local primary industries.Read moreRead less
Australian plague locust population genetics and migratory behaviour. The project will allow improved monitoring and forecasting of locusts in Australia and thereby help prevent locust outbreaks. Benefits will arise directly through greater effectiveness in reducing locust damage to crops, and indirectly to Australian rural industry generally through the economic benefits of reduced losses and locust control costs.

The project will allow improved monitoring and forecasting of locusts in Australia and thereby help prevent locust outbreaks. Benefits will arise directly through greater effectiveness in reducing locust damage to crops, and indirectly to Australian rural industry generally through the economic benefits of reduced losses and locust control costs. Environmental and social benefits will also arise from reduced, better targeted use of chemical insecticides. This in turn can produce secondary economic benefits, e.g. through enhanced growth and profitability of the organic beef industry within the main locust-outbreak area. Read moreRead less
