Evolution in tooth and claw: exploring the relationship between the radiation of marsupial herbivores and late Cenozoic climate change. Establishing how animals responded to past environmental changes is essential for understanding the ecology of modern species and managing them in light of contemporary climatic trends. By applying several novel analytical methods this project will unravel the links between the radiation of Australian marsupials and key stages in climatic evolution.
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
ARC Australia-New Zealand Research Network for Vegetation Function. Plant species vary widely in quantitative functional traits, and in their relations to climate, soils and geography. Global generalizations are emerging. Vegetation Function network will reach from plant function into genomics and crop breeding, into palaeoecology and vegetation history, into landscape management for carbon, water and salinity outcomes, into forecasting future ecosystems under global change, and into phylogeny, ....ARC Australia-New Zealand Research Network for Vegetation Function. Plant species vary widely in quantitative functional traits, and in their relations to climate, soils and geography. Global generalizations are emerging. Vegetation Function network will reach from plant function into genomics and crop breeding, into palaeoecology and vegetation history, into landscape management for carbon, water and salinity outcomes, into forecasting future ecosystems under global change, and into phylogeny, ecoinformatics and evolutionary theory. Across this span, working groups will target nine identified opportunities for breakthrough research. Each research target needs input from two or more disciplines. Together, the nine targets link across disciplines, as a network that spans from genomic to planetary scales.Read moreRead less
Occupational injury prevention in high temperature environments. This project aims to explore the contribution of heat as a risk factor in work-related illness and injury. Approximately 600 000 Australians experience a work-related illness or injury each year. Hot weather may directly or indirectly lead to accidents, but heat as a risk factor has not been systematically explored, and is particularly relevant in a warming climate. This project aims to improve safety and productivity in Australian ....Occupational injury prevention in high temperature environments. This project aims to explore the contribution of heat as a risk factor in work-related illness and injury. Approximately 600 000 Australians experience a work-related illness or injury each year. Hot weather may directly or indirectly lead to accidents, but heat as a risk factor has not been systematically explored, and is particularly relevant in a warming climate. This project aims to improve safety and productivity in Australian industry by generating new evidence and predictive models to inform injury prevention policy and guidance, and facilitating the development of practical, targeted resources. This project expects to add to the body of knowledge regarding workers’ health and safety and to be of benefit to industry and subpopulations at risk.Read moreRead less
Unsaturated zone functioning in a semi-arid flash flood driven climate. Groundwater is the only perennial water source in arid and semiarid zones, which encompass 1/3 of the global landmass and 70 % of Australia. We still do not fully understand how the unsaturated zone contributes to groundwater recharge in semi-arid zone floodplains. We will study the dynamics of soil moisture, and its contribution to groundwater recharge respective to hydrological regimes and weather patterns. We will measure ....Unsaturated zone functioning in a semi-arid flash flood driven climate. Groundwater is the only perennial water source in arid and semiarid zones, which encompass 1/3 of the global landmass and 70 % of Australia. We still do not fully understand how the unsaturated zone contributes to groundwater recharge in semi-arid zone floodplains. We will study the dynamics of soil moisture, and its contribution to groundwater recharge respective to hydrological regimes and weather patterns. We will measure direct responses to flood events using loggers and compare them to indirect measurements inferred from hydrochemical and isotope tracer models to better understand recharge patterns, evaporative losses, and interactions between surface runoff, floodplains, and aquifers at different positions in the landscape.Read moreRead less
Faunal responses to environmental change and isolation on an Australian land-bridge island. Establishing how faunas responded to past isolation and environmental changes offers great potential for predicting long-term impacts of habitat fragmentation. By combining novel methods we will track extinction rates, diet and body-size shifts on Kangaroo Island, the only known land-bridge island with a fossil record spanning the past 100,000 years.
Improving prediction of rocky reef ecosystem responses to human impacts. This project aims to improve our understanding of inshore ecosystems to facilitate better management of our living marine heritage. The project first aims to extend field datasets on the density and distribution of thousands of marine fishes, invertebrates and macro-algae. These will then be combined using recent advances in quantitative ecological modelling to describe transfer of biomass between species at hundreds of sit ....Improving prediction of rocky reef ecosystem responses to human impacts. This project aims to improve our understanding of inshore ecosystems to facilitate better management of our living marine heritage. The project first aims to extend field datasets on the density and distribution of thousands of marine fishes, invertebrates and macro-algae. These will then be combined using recent advances in quantitative ecological modelling to describe transfer of biomass between species at hundreds of sites, with a primary focus on southern Australia. It is anticipated that this will provide site-level indices of major food web processes that, when combined with ‘before, after, control, impact’ data, will improve prediction of ecological consequences of fishing, climate change, pest outbreaks and pollution.Read moreRead less
