Genome-level insight into the dynamics of a model coral microbiome. The aim of the project is to examine structural and functional microbiome dynamics in an ecologically important coral on the Great Barrier Reef along a natural temperature gradient. Microorganisms form an intimate symbiotic relationship with corals and are critical to their health. However, the microbiome can be disrupted by environmental perturbations, including higher-than-normal ocean temperatures, leaving the coral susceptib ....Genome-level insight into the dynamics of a model coral microbiome. The aim of the project is to examine structural and functional microbiome dynamics in an ecologically important coral on the Great Barrier Reef along a natural temperature gradient. Microorganisms form an intimate symbiotic relationship with corals and are critical to their health. However, the microbiome can be disrupted by environmental perturbations, including higher-than-normal ocean temperatures, leaving the coral susceptible to disease and bleaching. Currently, our understanding of how the microbiome composition and metabolic function change in response to seasonal temperature variation and disease is limited. This project is designed to provide insight into the role the microbiome plays in maintaining coral health and may aid in the long-term preservation of the reefs.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
Probing the response of Southern Ocean phytoplankton to changes in iron biogeochemistry, light and pH associated with climate change. Determining factors that influence the health and vitality of coastal and open-ocean regions is crucial to maintaining marine biodiversity and the Earth’s climatic balance. This research project will determine the role climate change and ocean acidification will have on the ability of Southern Ocean phytoplankton to flourish.

A pictorial and geochemical history of Great Barrier Reef changes. This project aims to determine the timing and associated drivers behind dramatic changes in coral communities on reef flat environments since European settlement. It will use Uranium-Thorium dating, palaeoecological and geochemical techniques, as well as spatial elevation surveys to determine the timing and cause of ecological transition for inshore coral communities. This project will contribute baseline knowledge on the timing ....A pictorial and geochemical history of Great Barrier Reef changes. This project aims to determine the timing and associated drivers behind dramatic changes in coral communities on reef flat environments since European settlement. It will use Uranium-Thorium dating, palaeoecological and geochemical techniques, as well as spatial elevation surveys to determine the timing and cause of ecological transition for inshore coral communities. This project will contribute baseline knowledge on the timing and mechanisms associated with dramatic declines in coral cover on inshore reefs of the world heritage listed Great Barrier Reef, and provide a robust scientific foundation for effective monitoring.Read moreRead less
Forecasting coral reef recovery with new data-driven dispersal models. This project aims to combine innovative mathematical methods and new genetic data to accurately predict the larval dispersal patterns of reef fish and corals. Larval dispersal is central to the ecology of coral reefs, and has vital implications for conservation. Most marine organisms spend their early life dispersing in the ocean, but our understanding of where these tiny larvae go is limited by sparse data and unvalidated mo ....Forecasting coral reef recovery with new data-driven dispersal models. This project aims to combine innovative mathematical methods and new genetic data to accurately predict the larval dispersal patterns of reef fish and corals. Larval dispersal is central to the ecology of coral reefs, and has vital implications for conservation. Most marine organisms spend their early life dispersing in the ocean, but our understanding of where these tiny larvae go is limited by sparse data and unvalidated models. Applied to extensive case-studies from Australia and across the western Pacific Ocean, these methods will be used to forecast and understand the recovery of fish and coral populations following severe disturbances. This will provide benefits such as enabling us to prioritise conservation actions in the aftermath of severe disturbances, including the catastrophic 2016 mass coral bleaching on the Great Barrier Reef.Read moreRead less
Larval dispersal and settlement mechanisms in the first genome-enabled Australian marine animal, Amphimedon queenslandica (Porifera). We know remarkably little about the lives of the enigmatic animals that live on our stunning coral reefs, except that many have a tiny larval stage that travels far beyond where the adults can go. This project explores how genomes and environment work together to ensure that larvae spread their species around to keep our reefs vibrant and diverse.

All you can eat: evolution of feeding in the largest animals on Earth. This project aims to establish how Baleen whales, the largest animals on Earth and major ecosystem engineers, evolved their signature filter-feeding strategy. Unlike other mammals, whales are toothless, and instead use a keratinous, comb-like sieve to filter vast amounts of small prey from seawater. Various approaches, including biomechanics, three-dimensional imaging, geochemistry and quantitative palaeobiology will unravel ....All you can eat: evolution of feeding in the largest animals on Earth. This project aims to establish how Baleen whales, the largest animals on Earth and major ecosystem engineers, evolved their signature filter-feeding strategy. Unlike other mammals, whales are toothless, and instead use a keratinous, comb-like sieve to filter vast amounts of small prey from seawater. Various approaches, including biomechanics, three-dimensional imaging, geochemistry and quantitative palaeobiology will unravel how and when filter feeding emerged, how it diversified over time, and whether its evolution correlated with past environmental change. The project is expected to reveal clues on how whales became one of the greatest ecological actors in the sea, and will benefit conservation by providing a glimpse into their future.Read moreRead less

Novel oxygen sensing tools for monitoring the effects of dredging on Australian seagrass communities. Seagrass meadows sustain marine biodiversity and the fishing industries on Australian coasts. Dredging of ports and shipping channels is contributing to their rapid global decline. The project will use state-of-the-art technologies in bio-optics and genomics to create a toolkit for seagrass managers to make informed decisions to safeguard seagrass meadows.
Heads or tails - which did echinoderms lose in the evolution of radial symmetry? Echinoderms, despite their unusual radial body plan, are closely related to chordates, but it is not known how this plan evolved. This project uses gene expression studies with uniquely suited Australian species to identify genes involved in radial body plan development and generate insights into origins of chordates and the vertebrate central nervous system (CNS).
