Survival and symbiont shuffling of transplanted fragments. (a) Survival rates one year after transplantation. Coloured bars refer to healthy fragments, whereas the grey fraction refers to transplanted fragments that still had some living tissue, but were mostly dead. Sample sizes (n) refer to the total number of fragments (alive or dead) present on the rack after 14 months (missing fragments were excluded). (b) Incidence of symbiont shuffling (i.e., change in the abundance of already present Symbiodinium). Dark grey indicates shuffling, whereas light grey indicates no change in symbiont community. Note that in none of the corals, new Symbiodinium types were acquired (i.e., symbiont "switching"). (c) Example of changes in Symbiodinium profile for a transplanted colony originating from the 'Upper Slope' habitat.
