What limits CO2 diffusion inside leaves? Dissecting the diffusion path with Arabidopsis mutants. Human induced increase in atmospheric carbon dioxide is now generally accepted as contributing to global warming. Forecasting our future impact relies on models of terrestrial photosynthesis which use a signature in the atmosphere created by plants when they discriminate against the heavy stable isotope of carbon during photosynthesis.

Human induced increase in atmospheric carbon dioxide is now generally accepted as contributing to global warming. Forecasting our future impact relies on models of terrestrial photosynthesis which use a signature in the atmosphere created by plants when they discriminate against the heavy stable isotope of carbon during photosynthesis. Discrimination between isotopes is affected by carbon dioxide diffusion within leaves and key steps in this process will be identified through the use of Arabidopsis mutants. Better representation of this process in models will improve estimates of terrestrial photosynthesis and climate change forecastsRead moreRead less

This project underpins the development of carbon dioxide (CO2)-neutral fuels for the future. Fuels account for around sixty seven percent of the global energy market. The Solar-Biofuels Consortium (www.solarbiofuels.org) is targeting this market by developing high efficiency second generation microalgal biofuel systems for the production of bio-diesel, bio-methane and bio-hydrogen (shown on Catalyst 2007). The solar-powered microalgal bioreactors can be located on non-arable land (eliminating competition with food production) and be coupled to carbon sequestration. Closed systems also minimize water use. This technology differs from most others (that is, clean-coal, nuclear, solar, wind, geothermal) as these target the electricity market.Read moreRead less

Multiphoton confocal microscope. Recent developments in light microscopy have revolutionised modern molecular and cellular biology. Dramatic improvements in microscope hardware and software and in the range of fluorescent markers used to tag selected cellular components now provide new and exciting opportunities to localise and determine the function of ions and molecules not only in preserved samples but also, most excitingly, in living cells.

Dramatic improvements in microscope hardware and software and in the range of fluorescent markers used to tag selected cellular components now provide new and exciting opportunities to localise and determine the function of ions and molecules not only in preserved samples but also, most excitingly, in living cells. The proposed multiphoton confocal microscope will allow researchers in Canberra to obtain high quality images of static and moving components in living cells and tissues and will facilitate the discovery of new knowledge that contributes to our understanding and control of development and disease in both plants and animals.Read moreRead less

Increasing concerns about greenhouse gas emissions and dwindling petroleum supplies have driven the development and commercialisation of fuel cells. The development of novel nanocomposite membranes will possibly lead to the materials breakthrough necessary for advancing both hydrogen and methanol fuel cell technologies, significantly benefiting Australian clean energy supplies and in particular transport vehicles and portable devices. The synthesis strategies generated will be applicable to creating other functional nanoporous or nanocomposite materials for wider application.

The management of greenhouse and other acid gas emissions is vital to a sustainable future of both the economy and the ecosystem. This project will develop novel nano-materials for gas separation by tethering organic functional groups to the surface of porous inorganic supports. These materials offer the promise of combining the high selectivity and high capacity of liquid phase absorption systems with the rapid transport rates of gas-solid adsorption systems. Success would open up several new possibilities for reengineering gas separation systems based on the use of these materials in solution, as solid phase adsorbents (pressure swing adsorption) and/or as permeselective gas membranes.Read moreRead less
Metabolite pools and their implications for plant responses to global change. Australian landscape management faces significant challenges from existing land practices and the effects of climate change.

Australian landscape management faces significant challenges from existing land practices and the effects of climate change. Effective management and targeted remediation requires an understanding of the processes that drive ecosystem function. The development of broadly applicable tools for the monitoring of plant and ecosystem health is therefore of considerable interest. Flexibility in core processes of plant function represents a significant opportunity to develop such tools. With a focus on plant metabolites, this project will characterise how Australian trees alter the allocation of resources to cope with environmental changes and produce metabolite-based selective traits for stress tolerance in Australian trees.

Effects of global climate change on marine phytoplankton: interactions between UV radiation and elevated atmospheric carbon dioxide levels. Global climate change is one of the most significant ecological challenges for the 21st Century. Phytoplankton contribute over 45% of the planet's annual net primary production and form the basis of most aquatic food chains. Conversely, some phytoplankton are toxic and cause problems in marine and fresh waters. Climate change can potentially disrupt aquatic ....Effects of global climate change on marine phytoplankton: interactions between UV radiation and elevated atmospheric carbon dioxide levels. Global climate change is one of the most significant ecological challenges for the 21st Century. Phytoplankton contribute over 45% of the planet's annual net primary production and form the basis of most aquatic food chains. Conversely, some phytoplankton are toxic and cause problems in marine and fresh waters. Climate change can potentially disrupt aquatic foodchains by its impact on primary production by phytoplankton or stimulating growth of potentially toxic forms. Our project will investigate the combined impact of increasing carbon dioxide and ultraviolet light on phytoplankton and thereby help climate modellers assess the impact of climate change on aquatic ecosystems and particularly on the nation's and the world's fisheries.Read moreRead less
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.
