  		Fig. 1. Lobophyllia corymbosa clones. (a) Post-budding stage characterized by tissues connecting between individual polyps (see white arrows); these connecting tissues later die, transforming the colony into a clone of solitary polyps (b,c). (d) During the night, polyp body columns expand, causing intraclonal contacts between individual polyps (see white arrows). (e) The center of a clone from which an intact polyp was removed for 14C-labeling. (f) `Hot' polyps wrapped with a plastic collar, reattached in their original clone. Scale bars, 5 cm.

  		Fig. 2. A schematic diagram of the 14C-labeling and sampling locations in Lobophyllia corymbosa clones. Forty-eight hours after reattachment of the `hot' polyp to the experimental clones, we sampled four fragments (marked as black circles) from each clone, using a round stainless-steel corer that enabled collection of similar-sized fragments (1 cm2 each). One fragment was taken from the `hot' polyp, one from the injured polyp adjacent to the hot polyp (injury size, 2 cm2), one from an intact polyp also adjacent to the hot polyp, and one from an intact remote polyp. 14C activity in the tissues of each fragment was determined by liquid scintillation counting.
