In a landmark effort to combat the devastating effects of climate change, a new global alliance with key leadership from the University of Hawai驶i at M膩noa has been established to create a "Noah驶s Ark" for coral reefs.

The initiative, in BioScience, focuses on building a worldwide network of coral biorepositories to safeguard the of these vital ecosystems.

The research, led by Mary Hagedorn of the UH M膩noa Hawai驶i Institute of Marine Biology and the Smithsonian's National Zoo and Conservation Biology Institute, highlights the critical need for a proactive conservation strategy. With continuing to rise, the alliance aims to provide a critical safeguard against extinction by preserving coral genetic material in biosecure facilities.

'A bold plan to save coral'

"This is an urgent and ambitious endeavor," said Hagedorn, lead author of the study. "By integrating and standardizing our processes globally, we can ensure that we have the resources to not only prevent extinction but also to support long-term coral adaptation, resilience and restoration."

The network will use a three-pronged approach to conservation: frozen nonliving tissue samples, live coral colonies in aquaculture, and cryopreserved (deep-freezing process) samples of frozen and live coral. This innovative approach provides a last-resort safety net, ensuring that essential bio鈥攁nd genetic diversity can be preserved for future generations.

The global biorepository network will be instrumental in developing new, stronger types of coral, because coral can now be spawned in captivity. Therefore, this network can be used to restore damaged reefs and help them survive in a changing climate today while holding other material for the future. The publication calls on the scientific community, conservation organizations and governments to support this for the future of marine biodiversity.
