Risk and recovery

"Examining the resilience, recovery and remediation of coral reefs"

Can corals cope with a warmer world?

This is just one of the burning questions being investigated by the Risk and Recovery team.

They are exploring the ability of coral to adapt to warmer seas, the possibility of breeding heat tolerant corals, and developing a long-term outlook on different heating scenarios.

Studying what happens in the cells when corals are stressed, during coral bleaching for example, gives scientists and insight into how the coral community as a whole copes under pressure.

Our Research

This research is crucial to improving conservation management of the Great Barrier Reef. This research analyses the resilience of tropical marine ecosystems to natural and human induced disturbances. The scientists examine the risks and threats to the Great Barrier Reef and use computer models to predict the fate of coral reefs. By exploring the ability of damaged reefs to self-remediate researchers are hoping to develop technologies for reef restoration. They are also learning about how reefs are connected in a bid to identify which reefs self-recruit and which ones source others. This information will help reef managers to pin point reefs of importance.

Reef Recovery

Our Team

A wide range of expertise exists within the Risk and Recovery team including skills in Geographical Information System, statistical analysis, spatial analysis, geospatial modelling, coral reef ecology, taxonomy, evolutionary biology, coral physiology and coral genetics.
 

Coral Reef Ecology
-Coral reef ecology 

A major long term project of this team is a photographic study of 28 fixed sites that documents composition of coral reefs and changes in size and species over time in a range of habitats. The scope of the project extends from very sheltered inshore reefs to exposed choppy outer reefs.

Reef Connectivity

Understanding how currents connect reefs and how this impacts on recruitment is crucial to identifying reefs of importance, e.g. source reefs. AIMS researchers have developed sophisticated hydrodynamic models to forecast the probability of a reef reseeding from the surrounding reefs. This predictive model is in the process of being tested and refined based on studies on movement of particles, larval loadings and genetic connectivity. The way species and their genes disperse over their range has major consequences on many ecological and evolutionary features, including the potential for local adaptation. An accurate assessment of dispersal is necessary to identify source and sink reefs, information that will aid in the choice of areas to be protected.

Corals and climate change

As we move into a warmer world this team examines how increasing temperature will affect corals on the Great Barrier Reef. Scientists are investigating the amount of thermal stress coral can handle. This will enable scientists to predict how the Great Barrier Reef will cope with future heat waves and projected rises in sea temperature. Seawater is forecast to warm by 2-6 degrees Celsius over the next century and rates of coral adaptation to these temperature increases are unknown. Coral bleaching experts at AIMS are examining the capacity of corals to adapt to warmer conditions in the short and long term.

Reef Futures

Reef Futures is a source of information and tools for exploring the effects of management and environmental change on reefs. It’s a place to go to explore what the future might bring. The Reef Futures group develops models, statistical tools, databases, and websites supporting coral reef ecology.

Biodiversity and recruitment

AIMS is assessing the ability for damaged reefs to recover following disturbance. The team will investigate new approaches for large-scale culture and delivery of coral larvae to reefs and compare the results with ongoing research into natural recruitment and post-recruitment survival.
