Advancing knowledge of microbial symbioses underpinning coral health and reef resilience and predicting their responses to climate change. Coral reefs are complex, diverse ecosystems in which microbial communities form associations with host corals. However, the roles these associations play in coral stress responses are unknown. This project unlocks the black-box of coral microbial complexity and determines how the reef’s smallest members have the greatest influence on reef health.

This will facilitate continued conservation and sustainable use of valuable ecosystem services in a changing world.
How sponges and bacteria maintain productivity on coral reefs. This project aims to listen in on conversations between a Great Barrier Reef sponge and its bacterial symbionts. Coral reefs thrive in nutrient-poor tropical seas by efficiently retaining and recycling essential elements. Marine sponges help coral reefs by co-operating with metabolically diverse bacterial symbionts via largely unknown mechanisms. Using an advanced genome-enabled sponge, invertebrate biology, microbiology, genomics an ....How sponges and bacteria maintain productivity on coral reefs.

Coral reefs thrive in nutrient-poor tropical seas by efficiently retaining and recycling essential elements. Marine sponges help coral reefs by co-operating with metabolically diverse bacterial symbionts via largely unknown mechanisms. Using an advanced genome-enabled sponge, invertebrate biology, microbiology, genomics and metabolomics, this project seeks to reveal genomic and metabolic details of the partnership, which could inform environmental restoration, pharmaceuticals and biotechnology.Read moreRead less

Summary
Tolerance of coralline algae to climate change in variable environments. This project aims to test whether organisms which regularly encounter low pH have greater tolerance to ocean acidification and why, and whether certain coralline algae can exert controls on their calcification that allows for greater tolerance to low pH. Coralline algae create and bind together reefs. Without them, both temperate and coral reefs as we know them would not exist. Understanding the extent to which tolerance to ....Tolerance of coralline algae to climate change in variable environments. This project aims to test whether organisms which regularly encounter low pH have greater tolerance to ocean acidification and why, and whether certain coralline algae can exert controls on their calcification that allows for greater tolerance to low pH. Coralline algae create and bind together reefs. Without them, both temperate and coral reefs as we know them would not exist. Understanding the extent to which tolerance to ocean acidification could be imparted to coralline algae through their environment or by physiological controls on calcification will enable us to better understand the fate of future reefs.Read moreRead less

Summary
Trait plasticity and the maintenance of functional diversity. This project aims to determine if trait plasticity mediates functional degradation of coral reefs. It will use natural environmental gradients to identify mechanisms that enable corals to persist in marginal habitats. The project will use three-dimensional imaging to measure how variability in traits influences functional redundancy. This will facilitate better predictions of the effects of environmental change on reef systems. Expect ....Trait plasticity and the maintenance of functional diversity. This project aims to determine if trait plasticity mediates functional degradation of coral reefs. It will use natural environmental gradients to identify mechanisms that enable corals to persist in marginal habitats. The project will use three-dimensional imaging to measure how variability in traits influences functional redundancy. This will facilitate better predictions of the effects of environmental change on reef systems. Expected outcomes include improved understanding of the response of coral reef ecosystems to environmental change and a framework for predicting reefs at risk of degradation. Benefits will be to both global biodiversity conservation and the provision of ecosystem services in reef dependent communities.Read moreRead less
Rewiring marine food webs: Predicting consequences of species range shifts. This project aims to predict how changes in climate-driven species distributions affect shallow marine communities globally.

This project aims to predict how changes in climate-driven species distributions affect shallow marine communities globally. Environmental change affects the structure, resilience and productivity of coastal marine ecosystems at regional and global scales. This project will combine global species distribution and trait databases, existing experimental data and targeted field sampling to develop, test and apply an integrated modelling platform to predict how global warming-driven changes in species distributions and their interactions affect the structure and dynamics of shallow marine communities. This project addresses a knowledge gap on how species’ redistributions and trophic dynamics produce communities, and aims to forecast future species abundances for sustainable marine ecosystem management.Read moreRead less
Poleward bound: mechanisms and consequences of climate-driven species redistribution in marine ecosystems. Global redistribution of Earth's species is widely recognised as a fingerprint of climate change. However, the physiological and ecological processes that underpin such shifts in the distribution of marine species are poorly understood. Even less is known about why species respond at different rates, and how such widespread changes will impact the structure and function of Australia's marin ....Poleward bound: mechanisms and consequences of climate-driven species redistribution in marine ecosystems. Global redistribution of Earth's species is widely recognised as a fingerprint of climate change. However, the physiological and ecological processes that underpin such shifts in the distribution of marine species are poorly understood. Even less is known about why species respond at different rates, and how such widespread changes will impact the structure and function of Australia's marine ecosystems. This research will address critical knowledge gaps of why and how species respond in vastly different ways to environmental change. Research outcomes will improve the capacity to predict responses of marine species and ecosystems to climate change and provide advice relevant to strategic management of valuable natural resources.Read moreRead less

In a world where few intact reefs remain, the goal of this project is to find ways to restore degraded reefs. Recent research has identified the species responsible for removing harmful algae from coral reefs, while advances in mariculture provide us with the capacity to rear these critically important reef fish species. Combining captive rearing, experimental manipulations, and a global analysis of the functional capacity of herbivorous fishes, in intact, degraded and human-modified systems, the research will explore the potential for restoring, or boosting, the capacity of reefs to withstand disturbance. The goal is to provide the scientific knowledge required to directly modify the key processes operating on coral reefs. Read moreRead less
