Ecosystem response to climate and anthropogenic disturbances: implications for greenhouse gas emissions and nutrient cycling. Humanity is challenged with climate change, greenhouse gas emissions, declining fertiliser reserves and a need to feed the world's growing population. This project will result in greater understanding of how ecosystems can respond to these challenges and provide a framework to help Australia manage its agricultural and natural reserves.
The role of epigenetic modifications in bovid adaptation to environmental change. This project will explore the role of epigenetic change, where gene expression is regulated without changing the deoxyribonucleic acid (DNA) sequence, in how animals adapt to rapid climate change. This project will trace epigenetic markers in ancient bison and cows through 30,000 years of climate change, and identify key adaptive genes for the cattle industry.
Diagnosing coral health tipping points under accelerating coastal hypoxia. This project aims to unlock the role hypoxia plays in shaping the healthy functioning of corals over space and time. Climate change and land use development are rapidly deoxygenating shallow water coral reefs and amplifying hypoxia exposure, yet we have no knowledge of the oxygen thresholds that sustain ‘normal’ coral functioning, or the mechanisms corals’ employ to tolerate hypoxia. This project will couple advanced oxyg ....Diagnosing coral health tipping points under accelerating coastal hypoxia. This project aims to unlock the role hypoxia plays in shaping the healthy functioning of corals over space and time. Climate change and land use development are rapidly deoxygenating shallow water coral reefs and amplifying hypoxia exposure, yet we have no knowledge of the oxygen thresholds that sustain ‘normal’ coral functioning, or the mechanisms corals’ employ to tolerate hypoxia. This project will couple advanced oxygen sensing, metabolic physiology and functional genomics techniques to transform our understanding of how corals and their associated microbial communities respond to reduced oxygen conditions, which is essential to improve coral reef ecosystem management.Read moreRead less

Summary
Elemental diagnostic of coral resilience to future reef climates. This project aims to integrate elemental stoichiometry, bio-elemental imaging and metabolomics to develop a common ‘elemental currency’ as an entirely new diagnostic of coral fitness. Coral reefs generate invaluable ecosystem services, but are on the verge of global collapse. Efforts to resolve coral traits that promote ecological resilience have been unable to integrate biological and environmental complexities of reef systems in ....Elemental diagnostic of coral resilience to future reef climates. This project aims to integrate elemental stoichiometry, bio-elemental imaging and metabolomics to develop a common ‘elemental currency’ as an entirely new diagnostic of coral fitness. Coral reefs generate invaluable ecosystem services, but are on the verge of global collapse. Efforts to resolve coral traits that promote ecological resilience have been unable to integrate biological and environmental complexities of reef systems into a unifying diagnostic of reef health. Natural extremes will provide the platform to identify key metabolic traits vital for future survival, to establish adaptive elemental signatures that can scale from organism to ecosystem. The project is expected to enhance capacity of marine managers and reef stakeholders to effectively manage and safeguard Australia’s reefs and the cultural and ecosystems.Read moreRead less
Mechanistic responses of phosphorus-limited forests to CO2 enrichment. Carbon dioxide continues to accumulate in the atmosphere, driven by human emissions. The future fate of the global forest carbon sink, which significantly slows CO2 increase in the atmosphere, helping to dampen climate change, remains poorly constrained, hindering mitigation and adaptation planning. A key gap concerns the role of phosphorus, crucial in limiting the productivity of Australian woodlands and tropical forests. Mo ....Mechanistic responses of phosphorus-limited forests to CO2 enrichment. Carbon dioxide continues to accumulate in the atmosphere, driven by human emissions. The future fate of the global forest carbon sink, which significantly slows CO2 increase in the atmosphere, helping to dampen climate change, remains poorly constrained, hindering mitigation and adaptation planning. A key gap concerns the role of phosphorus, crucial in limiting the productivity of Australian woodlands and tropical forests. Model-data fusion based on the results of a crossed CO2 x P experiment in Eucalyptus forest - EucFACE - will help close this vital knowledge gap, and leverage new mechanistic knowledge in a leading global model used for climate and emissions assessment.Read moreRead less

A specialised high throughput DNA sequencing technology called Single Molecule Real-Time (SMRT) sequencing developed by Pacific Biosciences (PacBio) is revolutionising biological research. SMRT sequencing allows researchers to discover important information in DNA and RNA molecules that are missed by other modern DNA sequencing approaches. It is expected that this facility will also be a key infrastructure resource for the wider scientific community, helping to address fundamental questions in biology.Read moreRead less
Size matters: evolution of body size of species in deep time. Global warming is predicted to form 'sick seas' and cause widespread stunted growth of taxa and ecosystem-wide dwarfism. Exactly how this works requires substantiation of both short-term empirical and experimental research as well as evidence from the deep-time fossil record. Using the high-resolution marine fossil record from the Permian-Triassic mass extinction ~252 million years ago, the most severe in the history of animals, this ....Size matters: evolution of body size of species in deep time. Global warming is predicted to form 'sick seas' and cause widespread stunted growth of taxa and ecosystem-wide dwarfism. Exactly how this works requires substantiation of both short-term empirical and experimental research as well as evidence from the deep-time fossil record. Using the high-resolution marine fossil record from the Permian-Triassic mass extinction ~252 million years ago, the most severe in the history of animals, this project will investigate how body size of marine species and communities evolved in response to the mass extinction and rapid global warming. It is expected that the project findings will help better understand the links between global warming, anoxia, hypercapnia, euxinia, ocean acidification, and species adaptation and evolution.Read moreRead less

Summary
Assessing the impact of global environmental change on the nutritional ecology of marsupial and insect folivores of Eucalyptus. Higher atmospheric carbon dioxide concentrations are predicted to alter plant nutrient and toxin content, while higher ambient temperatures may compromise the abilities of animals to metabolise plant toxins. This project will assess how climate change scenarios are likely to impact native marsupials and insects that rely on eucalypt leaves for food.

This project aims to establish an environmental radioactivity research centre, equipped with ultra-low background and high-resolution alpha and gamma spectrometry systems, radon detectors and radium delayed coincidence counters. The centre will address a critical demand in Australia for precise analysis of a large suite of natural and artificial radionuclides, which will be used as tracers and chronological tools to investigate key questions in oceanography and the mining and energy, archaeological, agricultural, and forestry sectors. The facility is expected to substantially increase expertise and training in radionuclides in Australia, and promote high-level research collaborations and outputs of both national and international significance. Major outcomes of the proposed facility include better understanding of how oceans regulate climate and improved capacity to assess effects of radiation on natural ecosystems.Read moreRead less

This project aims to deliver a comprehensive, integrated understanding of the capacity for resilience and drivers of response of highly vulnerable alpine species and communities to climate change. The project aims to determine how communities of interacting alpine plants, soil invertebrates and microbes can cope with or evolve to novel climatic conditions. The mountains are water towers critical to power supply and Australia's agricultural productivity. Understanding physiological tolerance and the potential for rapid evolutionary responses of plants, animals and communities is necessary to predict impacts of climate change on the future productivity of the vulnerable Australian Alps and to provide novel options for climate adaptation.
