Fig. 1: Coral bleaching and repigmentation responses to chemical bleaching and reinoculation.
From: Evidence for de novo acquisition of microalgal symbionts by bleached adult corals
A Symbiodiniaceae cell densities in hospite before and after chemical bleaching (n = 4 per species) and after reinoculation (n = 6 per species, except for E. lamellosa: n = 2; P.daedalea: n = 5; S. pistillata: n = 5). Error bars represent 1 standard error. B Images of corals before and after chemical bleaching and nine weeks after reinoculation with a cultured Cladocopium C1acro strain in the presence of sterilised sand (treatment RiS shown here). Both D. pallida and D. heliopora displayed thinner tissue after reinoculation resulting in their septa standing out. No tissue necrosis was recorded in these coral species, contrarily to E. lamellosa and P. lobata fragments. The Coral Watch Coral Health Chart depicts differences in pigmentation when a coral undergoes bleaching.
