How does warming prevent soil nitrogen availability from declining in response to elevated CO2? The sustainable use of the terrestrial environment depends upon maintaining ecosystem productivity which in turn depends upon nutrient availability within the soil. Increasing levels of CO2 in the atmosphere are known to decrease nutrient availability while warming prevents this from happening. The aims of this project are to determine how warming is able to prevent elevated CO2 concentrations from re ....How does warming prevent soil nitrogen availability from declining in response to elevated CO2? The sustainable use of the terrestrial environment depends upon maintaining ecosystem productivity which in turn depends upon nutrient availability within the soil. Increasing levels of CO2 in the atmosphere are known to decrease nutrient availability while warming prevents this from happening. The aims of this project are to determine how warming is able to prevent elevated CO2 concentrations from reducing soil N availability and hence productivity in a native grassland ecosystems. This is important, as it will allow likely problems caused by global climate change to be predicted by increasing the understanding of the underlying mechanisms as well as improving the management of grasslands in an environmentally sustainable way.

CaGaWaLo: regulation of carbon gain and water loss by woody vegetation. Trees and shrubs are widely perceived as central to solving problems of national and international significance. Seed funding is sought to facilitate establishment of a research network focused on their ability to sequester carbon and transmit water to the atmosphere. The proposed network is broadly based in plant physiology and ecology and contains a strong cross-section of leading international expertise in relevant sub- ....CaGaWaLo: regulation of carbon gain and water loss by woody vegetation. Trees and shrubs are widely perceived as central to solving problems of national and international significance. Seed funding is sought to facilitate establishment of a research network focused on their ability to sequester carbon and transmit water to the atmosphere. The proposed network is broadly based in plant physiology and ecology and contains a strong cross-section of leading international expertise in relevant sub-disciplines. By leveraging the huge pool of international expertise and focusing on a range of scales (from molecular to biosphere scales), this network will yield new ideas and approaches that will produce outputs and outcomes of national significance.Read moreRead less

SHRIMP SI - Microscale stable-isotope analysis in the Earth Sciences. Stable-isotope variations of elements such as oxygen, carbon, and sulphur, preserve the most profound records of environmental conditions during the geological, biological, and climatic evolution of Earth and planets. We will build a stable isotope ion microprobe (SHRIMP SI) to examine extraterrestrial and terrestrial systems in unprecedented detail. In terrestrial applications, the main issue is accuracy at the 0.01 percent ....SHRIMP SI - Microscale stable-isotope analysis in the Earth Sciences. Stable-isotope variations of elements such as oxygen, carbon, and sulphur, preserve the most profound records of environmental conditions during the geological, biological, and climatic evolution of Earth and planets. We will build a stable isotope ion microprobe (SHRIMP SI) to examine extraterrestrial and terrestrial systems in unprecedented detail. In terrestrial applications, the main issue is accuracy at the 0.01 percent level for 20-micron spots, which we can apply to studies of development of life on Earth, climatic records, weathering, and formation of ore bodies. Sample return missions of solar wind and comets will provide unique samples related to the formation of our solar system.Read moreRead less

A New Generation Noble Gas Mass Spectrometer Facility for Advanced Research in the Earth, Planetary and Environmental Sciences. The current proposal, to establish a new Noble Gas Analytical Consortium for noble gas chronological and geochemical analyses, will generate new knowledge on the evolution of the Earth, with profound implications for past climate change, landscape evolution, formation of ore bodies, and terrestrial geodynamics. Consequently, the facility will conform to the National Res ....A New Generation Noble Gas Mass Spectrometer Facility for Advanced Research in the Earth, Planetary and Environmental Sciences. The current proposal, to establish a new Noble Gas Analytical Consortium for noble gas chronological and geochemical analyses, will generate new knowledge on the evolution of the Earth, with profound implications for past climate change, landscape evolution, formation of ore bodies, and terrestrial geodynamics. Consequently, the facility will conform to the National Research Priority of 'An Environmentally Sustainable Australia'. The new facility will ensure that Australian research remains at the forefront of international science development and will also provide essential training for the next generation of Australian scientists.Read moreRead less
ARC Research Network for Understanding and Managing Australian Biodiversity. Biodiversity research is strong in Australia but is highly uncoordinated and, along with recent major breakthroughs in both theory and techniques, has highlighted the need for a Network to properly integrate research and focus it on the most appropriate scale.

Biodiversity research is strong in Australia but is highly uncoordinated and, along with recent major breakthroughs in both theory and techniques, has highlighted the need for a Network to properly integrate research and focus it on the most appropriate scale. This Network aims to bring together a diverse spectrum of highly experienced and early career researchers to pool their ideas and expertise to allow them to determine how best to describe Australia's current biodiversity and the biological and environmental history leading up to the present. A major outcome will be the ability to predict the impacts of environmental change on biodiversity to assist management decisions across Australia, with lessons of global importance.Read moreRead less

Our capacity to adapt to changes in water availability, agricultural productivity, the likelihood of species extinctions, and risks to human health will be enhanced through the Network's use of frontier technologies. The enhanced capacity to use data and model the Earth System will allow policymakers to make more informed decisions with regard to water, biodiversity, human health, industry and agriculture sustainability; thereby enhancing the national capacity to respond to climate change and variability and securing our common interest.Read moreRead less
Impact of Metal - Reactive Oxygen Species (ROS) Interactions on Growth and Toxicity of Ichthyotoxic Algae in Australian Coastal Waters. Toxic algal blooms in estuarine and coastal waters can have devastating economic and ecological impacts but remarkably little is known about the factors that control either organism growth or toxin severity. Recent studies suggest that the interplay between delivery of the nutrient trace metals iron and copper and the method via which the organism acts to assimi ....Impact of Metal - Reactive Oxygen Species (ROS) Interactions on Growth and Toxicity of Ichthyotoxic Algae in Australian Coastal Waters. Toxic algal blooms in estuarine and coastal waters can have devastating economic and ecological impacts but remarkably little is known about the factors that control either organism growth or toxin severity. Recent studies suggest that the interplay between delivery of the nutrient trace metals iron and copper and the method via which the organism acts to assimilate these metals is critical to the generation and aggressiveness of the toxins produced. These processes will be investigated in this study and conceptual and mathematical models will be developed which will assist in assessing management options for estuarine and coastal environments.Read moreRead less
