In a Darwinian experiment, scientists are trying to raise “super corals” in a lab to save reefs from climate change.
in 2018, also said she wanted people to know how “intimately reef health is intertwined with human health.”
Rather than editing genes or creating anything unnatural, researchers are just nudging what could already happen in the ocean, she said. “We are really focusing first on as local a scale as possible to try and maintain and enhance what is already there.”“We have discovered lots of reasons why corals don’t bleach,” said Steve Palumbi, a marine biologist and professor at Stanford University.
But Palumbi thinks the assisted evolution work has a valuable place in coral management plans because “reefs all over the world are in desperate, desperate, desperate trouble.” “We asked them to gather all the most recent cutting-edge science that was really centered on innovative interventions in coral reef management,” Koss said. “And certainly, this assisted gene flow fits right in.”Scalability is one. Getting lab-bred corals out into the ocean and having them survive will be hard, especially since reintroduction has to happen on a local level to avoid bringing detrimental biological material from one region to another.
Scientists are testing delivery methods, such as using ships to pump young corals into the ocean and deploying small underwater robots to plant coral.
