Likewise, we have found that individual corals can change themselves to become more heat tolerant when living in a warmer environment, and that some individuals have a higher dose of 'heat resistant' genes that gives them an edge as well. Equitorial populations bleach at higher temperatures than the same species living further from the equator. Yet there are some limits. We have found few corals that are bleach resistant above 35 degrees. And poor physiological health makes them more bleaching sensitive.
