This research proposal offers a pioneering opportunity to develop treatments that overcome the negative impact of stress on reproduction. Specifically, knowledge generated in this project will be vital in the development of strategic defences against the impact of stress on reproduction. This project fundamentally addresses Research Priority 2: Promoting and maintaining good health. Given that suppression of reproduction by stress occurs in all mammalian species including humans, domestic animals and wildlife, being able to prevent or overcome stress-induced reproductive dysfunction will generate significant health, social, economic and ecological benefits.

Australia is the worlds largest beef exporter with the net value of beef export valued at $4.6 billion. The economy of rural and regional Australia relies upon cattle production with the industry bringing a total value to these communities of $7.4 billion. Cattle production in remote Australia is becoming less viable as input costs of production increase relative to income earned and the beef industry is keen to transform production methods. Protein is the major limiting nutrient in the Australian rangelands and this proposal will provide new information on how providing protein to cattle during critical periods in their pregnancy can 'program' the body composition of the growing calf to be optimal for the market.Read moreRead less
Evolutionary genetics of bovid genomes over 60,000 years. This project will provide data critical for understanding the genetic background of modern cattle and bison, and how humans have shaped factors such as milk yield, growth rates and muscle mass. It will also reveal genes and genomic regions that were favoured in the domestication process, including those potentially linked to genes of commercial interest for future research. This pioneering ancient DNA approach will also be applicable to a ....Evolutionary genetics of bovid genomes over 60,000 years. This project will provide data critical for understanding the genetic background of modern cattle and bison, and how humans have shaped factors such as milk yield, growth rates and muscle mass. It will also reveal genes and genomic regions that were favoured in the domestication process, including those potentially linked to genes of commercial interest for future research. This pioneering ancient DNA approach will also be applicable to a variety of other domestic crops and animals. The unique temporal analysis of microevolution will provide crucial data for genetic research, and groundproof our attempts to analyse the timing and nature of human evolutionary history, major domestication events and inform conservation management.Read moreRead less

The extent of competition between the native and introduced herbivores of Kangaroo Island. This project examines grazing behaviour and competition among native and introduced herbivores to optimise limited resources in an ecologically fragile environment. The project will provide a biological basis for the development of management strategies to provide positive outcomes for the Kangaroo Island environment and potential economic benefit to the local and national economy. Environmental benefit in ....The extent of competition between the native and introduced herbivores of Kangaroo Island. This project examines grazing behaviour and competition among native and introduced herbivores to optimise limited resources in an ecologically fragile environment. The project will provide a biological basis for the development of management strategies to provide positive outcomes for the Kangaroo Island environment and potential economic benefit to the local and national economy. Environmental benefit includes the reduction of total grazing pressure on pastures and native vegetation of Kangaroo Island, which is one of Australia’s top 15 biodiversity ‘hot spots’, and thus help with conservation efforts on Kangaroo Island. Economic benefit will follow if farmers receive income from a currently wasted resource.Read moreRead less
Molecular mechanisms for seminal fluid signalling in reproduction. Male seminal fluid regulation of the female reproductive process influences fertility and fecundity in humans and animal species. Infertility and impaired reproductive function is a major economic constraint in livestock industries, and carries a substantial social and public health cost in humans.

Male seminal fluid regulation of the female reproductive process influences fertility and fecundity in humans and animal species. Infertility and impaired reproductive function is a major economic constraint in livestock industries, and carries a substantial social and public health cost in humans. This research will identify the active signalling molecules in seminal fluid and quantify their importance in reproductive success and health of offspring. The outcomes will inform development of new diagnostic assays for male fertility, and underpin strategic design of novel fertility treatments and products with applications in the human health and animal breeding industries.

This project aims to establish reference laboratories as biobanks for resistant isolate collections from veterinary diagnostic laboratories / surveillance programmes and a national research network to mitigate antimicrobial resistance in animals. Antimicrobial resistance in zoonotic/foodborne pathogens and livestock commensals is a global issue. This project will use mass-spectroscopy biotypers, information management software, robotic liquid handling and a research dairy to develop high-throughput screening technologies to rapidly determine major animal species’ resistance status, and research anti-infectives and vaccines for livestock diseases. This will improve the health and production of Australian livestock, leading to greater market access for high quality products.Read moreRead less

This technology allows genes to be manipulated via sperm in a wide range of animals besides mice, avoiding the need for a female in vitro fertilization regimen. He is curently applying interference RNA (siRNA) transgenically to manipulate genes in vivo. Together these two technologies offer immense possibilities to manipulate a wide range of species for economic, biotechnological or medical research purposes. Professor Shemesh wishes to come to Adelaide to establish these technologies there as parts of ongoing research projects, related to the physiology of the ovarian hormone relaxin in aging research.Read moreRead less

The VetCompass data service intends to collect real-time records from veterinary clinics and aggregate them for researchers to interrogate. It aims to provide Australian researchers with sustainable and cost-effective access to authoritative data from hundreds of practitioners in Australia and the United Kingdom. These data will be essential for research on disease distribution and determinants, and surveillance and diagnostics that underpin evidence-based practice. The expected outcomes include identification of the most prevalent disorders and their causes and optimal treatments. The data may also revolutionise clinical auditing in Australia, help the veterinary profession to rank research priorities, and inform companion animal and equine curricula in our universities.Read moreRead less

Aims: This project will define how ‘cryptic female choice’ affects reproductive outcomes through immune recognition of embryo histocompatibility genes, to modulate maternal nutrient provision and fetal growth.
Significance: The research will tackle an important knowledge gap in animal reproduction science, where poorly-understood male-female compatibility effects cause variation in breeding efficiency with major economic and environmental impact.
Expected outcomes: We expect to generate new understanding of the genes, immune response elements, and vascular changes that explain compatibility effects.
Benefits: The results will inform strategies to improve fertility in livestock animals, and in rare and threatened species.

Male seminal fluid is commonly thought simply to provide sperm for conception. This project aims to investigate a lesser known action of sperm: modifying the female immune response to increase the chances of reproductive success. The project aims to define the molecular pathway through which sperm interact with female cells, particularly how B-defensins on sperm bind to Toll-like receptors to stimulate female immune tolerance. The project plans to use embryo transfer and genetic mouse models to determine the physiological benefit of sperm signalling. Evidence that seminal fluid signalling operates in mammals to ensure optimal female reproductive investment would advance knowledge of the male contribution to the reproductive process.Read moreRead less
