Larvae-attracting gel could help repopulate decimated coral reefs
If you're hoping that reef-restoring coral larvae will settle down in damaged reefs, you can't just sit around and wait for it to happen. You have to get out there and entice the larvae, which is exactly what a new algae-based gel is designed to do.
Along with contributing greatly to the structural integrity of reefs, the algae-produced calcium carbonate also serves as a home to planktonic coral larvae. Led by Dr. Daniel Wangpraseurt, scientists at UC San Diego's Scripps Institution of Oceanography have now incorporated those metabolites into a gel that can be applied to degraded coral reefs.
