Eleven samples of a coral species (Acropora hyacinthus) were reciprocally transplanted from their native pool to a moderately variable heat pool (MV, in blue) or a highly variable heat pool (HV, in red). After the corals spent a period of time in their new environments, they were exposed to heat stress. The degree of resistance to bleaching by a coral colony is measured by the ratio of chlorophyll that remains in the corals after heat stress compared to non-heat stressed controls.
