Hope for rare corals

Posted on: Friday, 24 October 2008

What researchers thought were the most-threatened corals were actually taking care of their species by breeding hybrids. This makes me happy, but it doesn’t mean that we can go on ruining reefs. Remember, these creatures take ages to grow.

hundreds of corals are now on the red list of threatened species. It is often assumed that rare coral species face higher risks of extinction than common species because they have very small effective population sizes
When we studied some particularly rare species of Acropora (staghorn corals), which you might expect to be highly vulnerable to extinction, we found some of them were actually hybrids
This breaks all the traditional rules about what a species is.
it is even possible that the rare corals of today could become the common corals of the future
makes a lot of genetic sense if you are rare and the next colony of your species may be hundreds of kilometres away
