Just as individual humans handle stress differently, so do corals. Even coral colonies of the same species, growing side by side, vary in their tolerance to pressures such as heatwaves., we discovered surprising new evidence of variable heat tolerance in corals. As the world's oceans warm, these differences are important.to reduce the rate of ocean warming. As humanity works towards that goal, interventions may buy time for corals to survive in their warming environments.
Afterwards, we measured the amount of pigment left in the coral fragments, which directly aligns with the amount of algae left in the coral's cells. So what did we find? Under our experiments, the amount of pigment retained under high temperatures varied from 3% to 95%. This means at high temperatures, some coral colonies completely bleached while others seemed barely affected.
However, aspects of the marine environment may nurture, or hinder, a coral's heat stress response. These include water temperatures, nutrient conditions, and the symbiotic algae living inside coral tissue.
