Smithsonian & Partners Pioneer Method to Boost Endangered Coral Populations
Description:
Scientists from the Smithsonian Conservation Biology Institute (SCBI) and partners in Florida and Curaçao have become the first to use cryopreserved (frozen) coral sperm to support gene migration of coral populations that would otherwise remain geographically and genetically isolated. Because live corals are difficult to move safely between locations for breeding, the technique provides an effective way for conservationists to mix coral genes from different populations with the aim of making offspring more resistant to bleaching and disease. “We have combined the best of coral cryopreservation science with the best of coral reproductive science, coral rearing and husbandry,” said Mary Hagedorn, SCBI research scientist and co-lead author on a paper about the results, which the research team presented at the Reef Futures Conference in Florida Dec. 12. “This process—which involved the engagement, time and goodwill of scores of people, agencies, volunteers and divers—holds tremendous possibility for coral conservation and restoration.” Read the press release: http://ow.ly/GI3W30mXztH Read the paper: https://www.biorxiv.org/content/early/2018/12/10/492447
