Establishing research programs with Pacific neighbours benefits Australia's relations with Pacific Island countries generally. This project applies novel research methods to understanding human adaptations to long-term environmental and climatic fluctuations. It will address the National Research Priority goal of responding to climate variability by advancing our understanding of recent climate change in the Australia/Pacific region. It will show that Australian researchers can play a significant role in understanding the spread of humans across the Pacific, and the environmental adaptations required by populations in resource depleted environments. It will increase collaboration between research institutions focusing on the Australia/Pacific region.Read moreRead less
Resolving the threat of ocean deoxygenation to coral resilience. This project aims to uncover the role low oxygen plays in shaping healthy corals over space and time. Climate change and land use development are rapidly deoxygenating shallow water coral reefs, yet we have no knowledge of how less oxygen availability affects critical life history factors that govern coral resilience: growth, reproduction, and stress tolerance. This project unites a multidisciplinary team of experts to, for the fir ....Resolving the threat of ocean deoxygenation to coral resilience. This project aims to uncover the role low oxygen plays in shaping healthy corals over space and time. Climate change and land use development are rapidly deoxygenating shallow water coral reefs, yet we have no knowledge of how less oxygen availability affects critical life history factors that govern coral resilience: growth, reproduction, and stress tolerance. This project unites a multidisciplinary team of experts to, for the first time, couple advanced oxygen sensing, metabolic physiology, coral reproductive and stress biology to transform our understanding of oxygen thresholds that are diagnostic of reduced coral competitive fitness across life stages (adults, juveniles, larvae), needed to improve coral reef ecosystem management.Read moreRead less
A paradigm shift for predictions of freshwater harmful cyanobacteria blooms. This project aims to advance model predictions to generate novel insights into the triggers of freshwater harmful cyanobacteria blooms. Current models are poorly adapted for this purpose because they fail to account for antecedent environmental forcing. The project is expected to create new knowledge of cyanobacteria dynamics from simulating the adaptive responses of individual cyanobacteria cells, colonies or filaments ....A paradigm shift for predictions of freshwater harmful cyanobacteria blooms. This project aims to advance model predictions to generate novel insights into the triggers of freshwater harmful cyanobacteria blooms. Current models are poorly adapted for this purpose because they fail to account for antecedent environmental forcing. The project is expected to create new knowledge of cyanobacteria dynamics from simulating the adaptive responses of individual cyanobacteria cells, colonies or filaments to temperature, light and nutrient history. Three field studies will be used to validate a new individual based model. The outcomes of this project will be valuable for managing freshwater ecosystems that are increasingly subject to blooms in a warming climate, and for testing suitable mitigation and control strategies.Read moreRead less
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.

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
Climate change, larval dispersal and patterns of connectivity in coral metapopulations. Patterns of connectivity among coral populations are virtually unknown and these patterns are likely to change with changing climate. This project will test how temperature and pH will change patterns of coral dispersal in order to assist the design of an effective marine reserve network throughout the Great Barrier Reef.

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

This research will define and explain the responses of environmental processes to catastrophic vulcanism in West New Britain (P.N.G.) during the last 10,000 years. It will provide a crucial perspective to our understanding of past human-landscape relationships, thus filling an important gap in models, of social response to environmental conditions, which are merging from current archaeological and palaeoenvironmental research. The project will develop predictive models for environmental recovery under various conditions. The close relationship between this research and the ground breaking regional archaeological study allows this unique case study to contribute to a global discussion of past human-landscape relationships.Read moreRead less

The project aims to deliver management tools that will help mining companies to meet restoration targets and to improve the field of trait-based predictive restoration ecology. Species-rich kwongan shrublands of south-west Australia are a biodiversity treasure. Despite their global and national conservation value, little is known about which plant traits are most important for community assembly and diversity maintenance. This project plans to use plant functional traits related to nutrient and water acquisition to predict plant community assembly under different soil resource availabilities and thus assist in successful rehabilitation of this native vegetation after closure of sand-mining operations.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.
