I wonder if the fact that mature corals are stationary makes it harder for them to adapt. If the surviving corals are too far apart, it could be that they're unable to reproduce sexually. Coral larvae seem to be mobile until they find a structure to settle on, but if the larvae never have a chance to form... (Corals can also reproduce asexually via fragmentation, but that won't help with genetic diversity in the wild I'd imagine. Researchers seem to take advantage of this for selective breeding though.)
