Silicon: a novel solution to reduce water use and pest damage in wheat. The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si a ....Silicon: a novel solution to reduce water use and pest damage in wheat. The project aims to improve Australian wheat production by increasing drought resilience and reducing reliance on pesticides. This is achieved by incorporating amorphous silicon (Si), an abundant national resource. Si uptake by wheat has been proven to alleviate stress from drought and pests, but mechanisms and agronomic feasibility remain to be fully assessed. The project will deliver a mechanistic understanding of how Si alleviates stress in wheat, from gene to farm scale, providing cost-benefit analysis and a best–practice toolbox for implementation by farmers. Outcomes are anticipated to provide a cheaper and more environmentally sustainable solution to issues of water scarcity and yield losses to pests in Australia’s leading crop.Read moreRead less
Conservation biology of the largest Australian freshwater tortoise, the broad-shelled tortoise, Chelodina expansa - rare and endangered or cryptic and secure? The Murray is a highly managed river, with flows controlled by catchments and diversions. The combined impacts of water resource development, habitat modification and introduced species are astonishingly diverse, and include extinctions of some fish and invertebrates and depression of populations of many other species. Australia's largest ....Conservation biology of the largest Australian freshwater tortoise, the broad-shelled tortoise, Chelodina expansa - rare and endangered or cryptic and secure? The Murray is a highly managed river, with flows controlled by catchments and diversions. The combined impacts of water resource development, habitat modification and introduced species are astonishingly diverse, and include extinctions of some fish and invertebrates and depression of populations of many other species. Australia's largest chelid turtle, the broad-shelled turtle, is a high-level consumer thought to be particularly sensitive to these changes. We will use an innovative combination of non-destructive technologies to investigate the conservation biology of this species in the Lower Murray, where it is regarded as rare and where its biology is virtually unknown to inform conservation management and restoration initiativesRead moreRead less
Making Green Guard® greener: enhancing the efficacy of a biopesticide. The project aims to identify naturally occurring micro-organisms to increase the effectiveness of Green Guard ®, which is a biopesticide used against the Australian plague locust. The project will use next-generation sequencing and other molecular techniques to potentially identify candidate microbes or combinations of microbes that can be added to Green Guard to enhance locust susceptibility. The project also aims to quantif ....Making Green Guard® greener: enhancing the efficacy of a biopesticide. The project aims to identify naturally occurring micro-organisms to increase the effectiveness of Green Guard ®, which is a biopesticide used against the Australian plague locust. The project will use next-generation sequencing and other molecular techniques to potentially identify candidate microbes or combinations of microbes that can be added to Green Guard to enhance locust susceptibility. The project also aims to quantify the interactive impact of temperature and nutrition on immune function, disease resistance and host-plant quality of plague locusts; and to explore the combined effects of temperature, habitat and Green Guard, in combination with candidate microbes or pathogens, on the behaviour and collective movement of locusts. It is anticipated that this will have implications for management and control strategies.Read moreRead less
