Genetic variability makes some marine organisms resilient to
environmental change.
Rising acidity in the oceans is expected to have dire
consequences for organisms like coral, but some sea urchins have the genetic
tools to adapt to the inhospitable conditions, researchers have found. The
result, presented Monday at the Third International Symposium on the Ocean in a
High CO2 World in Monterey, California, is one of a few suggesting that some
organisms are more resilient than others to changes in ocean acidity.
