Summary
High throughput nitrogen analysis for ecological studies. Australian environments are unproductive partly because they contain little Nitrogen (N) and changes in atmospheric CO2 will exacerbate this. Furthermore, animals cannot extract all the N from the plants they eat. An assay has been developed that measures how much they can extract (available N) and it is intended to use it to measure habitat quality and the effects of climate change over large tracts of land. This requires thousands of ....High throughput nitrogen analysis for ecological studies. Australian environments are unproductive partly because they contain little Nitrogen (N) and changes in atmospheric CO2 will exacerbate this. Furthermore, animals cannot extract all the N from the plants they eat. An assay has been developed that measures how much they can extract (available N) and it is intended to use it to measure habitat quality and the effects of climate change over large tracts of land. This requires thousands of N analyses. The equipment we are requesting - a LECO combustion analyser, allows us to analyse samples quickly and safely and uses fewer chemicals and much less water than do traditional machines.Read moreRead less
Re-evaluating the role of tannins in Australian forest ecosystems. As atmospheric CO2 concentrations rise, eucalypts will respond by decreasing the amount of protein in the leaves and increasing the concentrations of toxins called tannins. Together this will have the effect of making the leaves harder for herbivores to eat and slower to break down on the forest floor. We have developed a new way of measuring these effects and will use it to show which eucalypt communities climate change will mo ....Re-evaluating the role of tannins in Australian forest ecosystems. As atmospheric CO2 concentrations rise, eucalypts will respond by decreasing the amount of protein in the leaves and increasing the concentrations of toxins called tannins. Together this will have the effect of making the leaves harder for herbivores to eat and slower to break down on the forest floor. We have developed a new way of measuring these effects and will use it to show which eucalypt communities climate change will most affect and so which forests will become less able to support fauna. Apart from contributing to the better management of Australian forests, this project also enhances the National Carbon Accounting System by measuring how tannins influence litter decomposition and explaining the link with leaf chemistry.Read moreRead less
Responses of southern Australian mammal faunas to climate change before and after human arrival. In the past 170 years, southern Australia mammals have suffered one of the worst extinction rates in the world. More losses are predicted in the face of global warming. This recent extinction wave follows a major extinction event that saw 90% of Australia's large animals disappear 60,000-40,000 years ago. The causes are hotly debated. Some researchers argue for a human cause, others suggest that clim ....Responses of southern Australian mammal faunas to climate change before and after human arrival. In the past 170 years, southern Australia mammals have suffered one of the worst extinction rates in the world. More losses are predicted in the face of global warming. This recent extinction wave follows a major extinction event that saw 90% of Australia's large animals disappear 60,000-40,000 years ago. The causes are hotly debated. Some researchers argue for a human cause, others suggest that climate change was to blame. This study will refine our knowledge of the timing and causes of these extinctions in southern Australia by assessing how communities responded to climate change in the lead-up to human arrival. It will provide vital information for managing the conservation of many modern species and guide us in limiting future losses.Read moreRead less
Climate change and ocean acidification: will southern ocean coccolithophorids be winners or losers? Implications for the global carbon pump. This proposal brings skills on morphotaxonomy, microalgal culturing, physiology and biogeochemistry into the flurry of international activity focusing on consequences of ocean acidification. Increasing atmospheric carbon dioxide (CO2) is predicted to reduce calcification in the phytoplankton Emiliania huxleyi, notably in the Southern Ocean. In contrast, hi ....Climate change and ocean acidification: will southern ocean coccolithophorids be winners or losers? Implications for the global carbon pump. This proposal brings skills on morphotaxonomy, microalgal culturing, physiology and biogeochemistry into the flurry of international activity focusing on consequences of ocean acidification. Increasing atmospheric carbon dioxide (CO2) is predicted to reduce calcification in the phytoplankton Emiliania huxleyi, notably in the Southern Ocean. In contrast, higher CO2 may stimulate photosynthesis and enhanced stratification may also select for E. huxleyi. These changes will affect foodwebs and the ability of the ocean to absorb CO2. Predicting the future success of this key organism is vital to understand the consequences of global change in Australian and Southern Ocean waters and to set targets for carbon emissions.Read moreRead less
Ancient DNA as a tool to study Australia's paleome: exploring climatic change, past biodiversity, extinctions and long-term survival of DNA. Restoration of Australian ecosystems can only occur if we know what plants, animals and insects used to live in the area before 'pest' species were introduced. This project will use ancient DNA obtained from 'poo' and cave sediments, that is thousands of years old, to discover what species used to live where and when. The ancient DNA profiles of past ecosys ....Ancient DNA as a tool to study Australia's paleome: exploring climatic change, past biodiversity, extinctions and long-term survival of DNA. Restoration of Australian ecosystems can only occur if we know what plants, animals and insects used to live in the area before 'pest' species were introduced. This project will use ancient DNA obtained from 'poo' and cave sediments, that is thousands of years old, to discover what species used to live where and when. The ancient DNA profiles of past ecosystems will allow us to make better decisions when trying to establish sustainable and 'natural' mainland and island sanctuaries. Ancient DNA is well preserved in some dry environments; this project will assess DNA preservation from sites all across Australia and use the DNA sequences to discover information about extinct animals and how past climate changes effected the native biota.Read moreRead less
Why our biota is unique: ecophysiological response, adaptive radiation and changing environments in Cainozoic Australia. We seek to resolve Cainozoic diversification and extinction patterns leading to the modern Australian biota. We propose a broad-scale, multi-disciplinary approach involving systematic palaeontology, palaeobiology, biostratigraphy, molecular and morphological systematics and physiology of modern organisms. For the first time, we will synthesise data on past climatic and environ ....Why our biota is unique: ecophysiological response, adaptive radiation and changing environments in Cainozoic Australia. We seek to resolve Cainozoic diversification and extinction patterns leading to the modern Australian biota. We propose a broad-scale, multi-disciplinary approach involving systematic palaeontology, palaeobiology, biostratigraphy, molecular and morphological systematics and physiology of modern organisms. For the first time, we will synthesise data on past climatic and environmental influences on the evolution of Australian plants, animals and community structure through time. This will provide a solid historical basis to develop management strategies for the Australian biota under different, future, climatic scenarios, and will also provide a biostratigraphic framework essential for high-resolution mineral and hydrocarbon exploration.Read moreRead less
Protecting the safe havens: will granite outcrop environments serve as refuges for flora threatened by anthropogenic climate change? Anthropogenic climate change threatens the Earth's biota and human society. By identifying areas that can act as refuges under projected climate conditions, adaptation and conservation activities can be focused where they will provide greatest benefit. This transdisciplinary project in the Australian global biodiversity hotspot examines the role of granite outcrops ....Protecting the safe havens: will granite outcrop environments serve as refuges for flora threatened by anthropogenic climate change? Anthropogenic climate change threatens the Earth's biota and human society. By identifying areas that can act as refuges under projected climate conditions, adaptation and conservation activities can be focused where they will provide greatest benefit. This transdisciplinary project in the Australian global biodiversity hotspot examines the role of granite outcrops as safe havens for species in the face of climate change. Knowing areas where species will retreat and maintain biodiversity under climate change will support decision making for protection of key refuges. Large financial, social and biodiversity returns follow from implementation of effective climate change adaptation management programs in Australian landscapes.Read moreRead less
New tools for managing ecosystem responses to climate change on the southern Great Barrier Reef. The Great Barrier Reef (GBR) underpins over $4 billions of economic activity each year. Recent evidence suggests that reefs like the GBR are vulnerable to climate change, which manifests itself at both local and global scales. Providing the tools for tracking and understanding these changes is vitally important to effective reef management strategies.

The Great Barrier Reef (GBR) underpins over $4 billions of economic activity each year. Recent evidence suggests that reefs like the GBR are vulnerable to climate change, which manifests itself at both local and global scales. Providing the tools for tracking and understanding these changes is vitally important to effective reef management strategies. This project will provide a major advance in our understanding and the tools available to manage the impacts of climate change. In doing so, it will also produce the first comprehensive and multidisciplinary look at how environmental variability impacts coral reef organisms from corals to seabird populations.Read moreRead less
Assessing the risk of ocean acidification for the Great Barrier Reef. The increase in greenhouse gases such as CO2 represents a challenge for coral reefs such as Australia's Great Barrier Reef (GBR). While the impact of greenhouse warming on coral reefs has been partially explored, the potentially serious implications of a decrease in ocean pH due have not been properly assessed. Detecting and understanding changes to carbonate concentrations and reef calcification are of great importance if ....Assessing the risk of ocean acidification for the Great Barrier Reef. The increase in greenhouse gases such as CO2 represents a challenge for coral reefs such as Australia's Great Barrier Reef (GBR). While the impact of greenhouse warming on coral reefs has been partially explored, the potentially serious implications of a decrease in ocean pH due have not been properly assessed. Detecting and understanding changes to carbonate concentrations and reef calcification are of great importance if managers are to respond strategically to potential ecological changes. This project directly addresses National Research Priority 1 of achieving 'An Environmentally Sustainable Australia' by addressing the priority goal of 'Responding to climate change and variability'.Read moreRead less
Understanding plant residue decomposition by linking organic matter chemistry and soil microbiology. Soils are an important source or sink for CO2. Currently we lack a fundamental understanding of plant residue decomposition and their transformation into various soil organic carbon (SOC) pools. Since these different pools of soil C are recycled back to atmosphere at different rates, a better understanding of the process is crucial for our ability to manage soil C and to predict the impact of man ....Understanding plant residue decomposition by linking organic matter chemistry and soil microbiology. Soils are an important source or sink for CO2. Currently we lack a fundamental understanding of plant residue decomposition and their transformation into various soil organic carbon (SOC) pools. Since these different pools of soil C are recycled back to atmosphere at different rates, a better understanding of the process is crucial for our ability to manage soil C and to predict the impact of management on SOC. For the first time we will combine detailed chemical analyses of soil organic matter fractions with determination of decomposition rates and microbial community structure; thereby also increasing the knowledge of how Australia's biodiversity is modulated.
