By integrating a highly skilled team with new approaches and breakthrough technologies, the program anticipates discovery science, enhanced environmental forecasting and optimised decision-making to advance Australia’s position as an influential Antarctic nation.
Expected outcomes include better environmental management, unparalleled strategic decision-support for an effective Antarctic Treaty, and new minds to address Antarctica’s new challenges.
Anticipated benefits are the means to transform environmental forecasting and management in the Antarctic, for Australia, and to the advantage of global security.Read moreRead less
Early evolutionary origins of mechanosensory transduction: structure, function and phylogenetic studies of the family of mechanosensitive channels in cell-walled organisms. The proposed project is based on the recent progress the applicants have made by (i) identifying a novel family of mechanosensitive (MS) channels in cell-walled organisms, which include Archaea and Bacteria (prokaryotes), as well as fungi and plants (eukaryotes), and (ii) determining basic aspects of the structural dynamics ....Early evolutionary origins of mechanosensory transduction: structure, function and phylogenetic studies of the family of mechanosensitive channels in cell-walled organisms. The proposed project is based on the recent progress the applicants have made by (i) identifying a novel family of mechanosensitive (MS) channels in cell-walled organisms, which include Archaea and Bacteria (prokaryotes), as well as fungi and plants (eukaryotes), and (ii) determining basic aspects of the structural dynamics of MscL, the prototype MS channel, using electronparamagnetic resonance spectroscopy and molecular dynamics simulations in combination with the patch clamp technique. The aim of the project is to elucidate the molecular principles underlying the function of MS channels, which is of fundamental importance for understanding of the biophysics and physiology of mechanosensory transduction throughout the biological world.Read moreRead less
Vulnerability of Australian savannas to climate change and variability. Australian savannas are productive and are culturally and biologically significant landscapes, but they are vulnerable to climate change. This project will determine savanna function (carbon and water balance) for the present and assess how sensitive they have been to past climate variability. The project will then address how they may respond to future climate change.

Summary
Tolerance of coralline algae to climate change in variable environments. This project aims to test whether organisms which regularly encounter low pH have greater tolerance to ocean acidification and why, and whether certain coralline algae can exert controls on their calcification that allows for greater tolerance to low pH. Coralline algae create and bind together reefs. Without them, both temperate and coral reefs as we know them would not exist. Understanding the extent to which tolerance to ....Tolerance of coralline algae to climate change in variable environments. This project aims to test whether organisms which regularly encounter low pH have greater tolerance to ocean acidification and why, and whether certain coralline algae can exert controls on their calcification that allows for greater tolerance to low pH. Coralline algae create and bind together reefs. Without them, both temperate and coral reefs as we know them would not exist. Understanding the extent to which tolerance to ocean acidification could be imparted to coralline algae through their environment or by physiological controls on calcification will enable us to better understand the fate of future reefs.Read moreRead less
Benefits of NatraGuard (a milk-derived protein) on skeletal muscle mass and development: in vivo and in vitro investigations in mice. The capacity of NatraGuard (derived from milk) to increase the mass of skeletal muscles will be scientifically investigated; in vivo using growing and adult mice and with muscle cells in culture to identify the novel mechanism of this hypertrophic effect. This research has many potential clinical, agricultural and commercial applications.
Australian savannah landscapes: past, present and future. Australian savannahs are productive and culturally and biologically significant landscapes but are vulnerable to climate change. The project will determine savannah function (carbon and water balance) for the present and assess how sensitive they have been to past climate variability. The project will then address how they may respond to future climate change.
Impact of global stressors on the metabolic balance of the coastal Indian Ocean. The pelagic community metabolic balance characterises the role of ocean biota as a sink or source of carbon dioxide. No estimates of net community metabolism are available for the Indian Ocean, which is a major gap in our knowledge. Key environmental stressors, UVB radiation and warming (particularly heat wave events) have the potential to impact on pelagic community metabolism, especially along the Western Australi ....Impact of global stressors on the metabolic balance of the coastal Indian Ocean. The pelagic community metabolic balance characterises the role of ocean biota as a sink or source of carbon dioxide. No estimates of net community metabolism are available for the Indian Ocean, which is a major gap in our knowledge. Key environmental stressors, UVB radiation and warming (particularly heat wave events) have the potential to impact on pelagic community metabolism, especially along the Western Australian coast. This project addresses the lack of estimates of plankton metabolic balance in the coastal Indian Ocean and assess how multiple concurrent stressors can affect pelagic metabolism in the coastal Indian Ocean in a context of global change.Read moreRead less
Non-CO2 greenhouse gas emissions in afforested ecosystems in southeastern Australia - fluxes, processes and regional budget. There are no data available about the extent of emissions of the non-CO2 greenhouse gases nitrous oxide and methane from soils of forest ecosystems in Australia and the current methodolgy to quantify these emissions contains high uncertainties. Using the latest technology available we propose to i) measure emission rates of afforested ecosystems for non-CO2 greenhouse gase ....Non-CO2 greenhouse gas emissions in afforested ecosystems in southeastern Australia - fluxes, processes and regional budget. There are no data available about the extent of emissions of the non-CO2 greenhouse gases nitrous oxide and methane from soils of forest ecosystems in Australia and the current methodolgy to quantify these emissions contains high uncertainties. Using the latest technology available we propose to i) measure emission rates of afforested ecosystems for non-CO2 greenhouse gases in relation to previous land-use in southeastern Australia, ii) identify the processes controlling the emissions, iii) use the obtained data to calibrate a biogeochemical model, and iv) use the model to estimate regional inventories for non-CO2 greenhouse gas emissions in southeastern Australia.Read moreRead less

The direct benefit for Australian science consists of: (i) strengthening international links with leading overseas laboratories, and (ii) accessing the state-of-the-art expertise not available in Australia. The acquired knowledge will aid in developing and designing artificial tactile sensors inspired by their biological models studied in this project. Long-term, the project is expected to make an original contribution towards developing new technologies and novel medical applications, both of which promise to be of great national benefit.Read moreRead less
