The new recruits continue to grow


Now that the new coral recruits are taking up the algal symbionts, our next step is to sample these corals and determine the type of symbionts that they are initially acquiring. Our goal is to determine if these are the same types of symbionts that the adult corals harbor and if not, to ascertain (1) when the assemblage that is found within the adult is established and (2) what is the basis for the type of symbiont that the the coral acquires doing its ontogeny. Here are photos taken by the staff at the UM Hatchery while they were doing the first sampling of the recruits. As you can see - the recruits look great!

And the recruits are infected!!!

We just received word today that the M. faveolata recruits that we left at the Univ. of Miami Experimental Hatchery (see below) have acquired algal symbionts. In this species, as with most hard corals, the newly settled coral acquire its symbionts anew each generation. Our next step will be to sample these corals to determine what symbiont type that they initially take up - which is one of the goals of this study.
