Corals crossbred to boost genetic diversity for Florida and Caribbean reefs

In a groundbreaking, first-of-its-kind milestone for coral restoration, scientists from the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science, Tela Marine and The Florida Aquarium have outplanted elkhorn corals onto a Miami reef that were produced by breeding elkhorn parents from Florida with elkhorn parents from an unusually warm reef in Honduras. These “Flonduran” elkhorn corals could hold the genetic keys to increase the diversity of Florida’s remaining elkhorn coral gene pool, while also potentially enhancing their heat tolerance and overall resilience.
