Corals Saving Corals
Disease-Resistant Corals Can Help ‘Rescue’ Vulnerable Ones
"Under the right living arrangement, disease-resistant corals can help “rescue” corals that are more vulnerable to disease, found a study from the University of California, Davis, that monitored a disease outbreak at a coral nursery in Little Cayman, Cayman Islands.
The study, published in the journal Scientific Reports, found that when people grow corals of the same genotype — or genetic makeup — together, those corals are more vulnerable to disease than corals that grow among a mixture of genotypes. The study further found that some vulnerable corals can be “rescued” by resistant genotypes."
