New super corals bred by scientists to resist global warming could be tested on the Great Barrier Reef within a year as part of a global research effort to accelerate evolution and save the “rainforests of the seas” from extinction.
Researchers are getting promising early results from cross-breeding different species of reef-building corals, rapidly developing new strains of the symbiotic algae that corals rely on and testing inoculations of protective bacteria. They are also mapping out the genomes of the algae to assess the potential for genetic engineering.
Innovation is also moving fast in the techniques need to create new corals and successfully deploy them on reefs. One breakthrough is the reproduction of the entire complex life cycle of spawning corals in a London aquarium, which is now being scaled up in Florida and could see corals planted off that coast by 2019.
“It is a story of hope, rather than saying ‘it’s all going to die and there’s nothing we can do about it’,” said Prof Madeleine van Oppen, from the Australian Institute of Marine Science and the University of Melbourne.
