Why are complex habitats more diverse? This project aims to develop and test theory for the ubiquitous relationship between habitat complexity and biodiversity. Whether in forests, grasslands, kelp forests or coral reefs, habitat complexity is increasingly being flattened by natural and human-based processes. The project will integrate novel three-dimensional habitat models with established ecological theory, and then validate the theory on coral reefs that have undergone disturbances with diffe ....Why are complex habitats more diverse? This project aims to develop and test theory for the ubiquitous relationship between habitat complexity and biodiversity. Whether in forests, grasslands, kelp forests or coral reefs, habitat complexity is increasingly being flattened by natural and human-based processes. The project will integrate novel three-dimensional habitat models with established ecological theory, and then validate the theory on coral reefs that have undergone disturbances with different effects on complexity (cyclones and bleaching). This project will significantly advance the predictive capacity of biodiversity risk assessments of these threatened ecosystems and potentially others worldwide.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. 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
Reef Breath Testing (RBT): exhaled volatile-gas biomarkers of coral health. This Project aims to uncover volatile gas "fingerprints" of coral reef taxa and how they are diagnostic of healthy reef functioning over space and time. All organisms emit distinct volatile gases via physiological fine-tuning and signalling as their environments change. Whilst coral reef taxa and coral reefs are hotspots for volatile gas emissions, which gases are produced, when and why, is entirely unexplored. This proj ....Reef Breath Testing (RBT): exhaled volatile-gas biomarkers of coral health. This Project aims to uncover volatile gas "fingerprints" of coral reef taxa and how they are diagnostic of healthy reef functioning over space and time. All organisms emit distinct volatile gases via physiological fine-tuning and signalling as their environments change. Whilst coral reef taxa and coral reefs are hotspots for volatile gas emissions, which gases are produced, when and why, is entirely unexplored. This project unites a multidisciplinary team of experts to, for the first time, couple volatile gas assessment, metabolic physiology and functional genomics techniques to transform understanding of how key volatile gases underpin coral resilience to stress and disease, which is essential to improve coral reef ecosystem management.Read moreRead less

Summary
Monitoring coral reef health from space: how herbivore behaviour alters reef structure. This research seeks to understand how both fishing and marine reserves can shape coral reef landscapes by changing the way herbivores behave while foraging for food. It will use an innovative approach combining ecological theory with satellite imagery, resulting in a predictive tool for resource managers both in Australia and globally.
The recovery of seagrass beds: the role of catchments and options for management responses. Seagrass beds once dominated tidal flats but are disappearing at an increasing rate due to human actions, both in Australia and around the world. This project will develop an understanding of the processes that cause these losses, the factors that prevent seagrass-bed re-establishment, and provide a framework for evaluating alternative management options.

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
Balancing estuarine and societal health in a changing environment. This project aims to facilitate sustainable development in a fast-growing coastal region (Peel-Harvey, south-western Australia). By exploiting 30+ year data sets for this catchment-estuary system and integrating ecological, hydrological, biogeochemical, modelling and socio-economic expertise, this project seeks to link primary catchment drivers to estuarine health response (up to higher fauna), quantify estuarine ecological healt ....Balancing estuarine and societal health in a changing environment. This project aims to facilitate sustainable development in a fast-growing coastal region (Peel-Harvey, south-western Australia). By exploiting 30+ year data sets for this catchment-estuary system and integrating ecological, hydrological, biogeochemical, modelling and socio-economic expertise, this project seeks to link primary catchment drivers to estuarine health response (up to higher fauna), quantify estuarine ecological health and ecosystem services under historical and future scenarios, and test resilience across the human–natural system. Envisaged outcomes include evidence-based catchment planning solutions that optimise trade-offs between socio-economic development goals and minimal downstream impacts on estuarine health.Read moreRead less
Genetic solution or dilution: can selective breeding future-proof oysters? This project aims to test whether the flow of beneficial genes from farmed oysters into wild oysters can make natural oyster beds and the ecological communities that they support more resilient to environmental change. Wild oysters are critical to the function of coastal ecosystems. However, wild oyster populations are threatened by environmental change in Australia and around the world. Selectively bred oysters bearing s ....Genetic solution or dilution: can selective breeding future-proof oysters? This project aims to test whether the flow of beneficial genes from farmed oysters into wild oysters can make natural oyster beds and the ecological communities that they support more resilient to environmental change. Wild oysters are critical to the function of coastal ecosystems. However, wild oyster populations are threatened by environmental change in Australia and around the world. Selectively bred oysters bearing stress resistance genotypes are now commercially farmed in many estuaries on Australia's east coast and may be used to bolster wild oyster populations. This project endeavours to develop novel genetic strategies to future-proof oysters. Thus, the outcome of this project has potential to benefit entire ecosystems that depend upon oysters.Read moreRead less

This project aims to restore a key habitat forming-seaweed and its ecosystem, by integrating experimental ecology, population genetics, eco-engineering and restoration ecology. Habitat degradation causes worldwide loss of biodiversity and ecosystem function, increasingly needing active restoration of ecosystems. However, restoration efforts often lack the critical ecological understanding for success, largely ignore major habitats, and in marine systems rarely happen at the scale of the degradation. This innovative approach, could be adopted globally to restore these crucial marine habitats. Anticipated outcomes are the re-establishment of commercially harvestable resources and new tools for active conservation of critical marine habitats.Read moreRead less
