Invasive species benefit from ocean acid

摘要

Ocean acidification could be helping migratory algae, jellyfish, crabs and shellfish become established in new marine ecosystems. Some of these species likely reached their new home via ship ballast water exchange. Irrespective of how they found their way, the slimy, jelly-like creatures are far more tolerant of rising CO_2 levels than those with hard structures like corals, since shells and skeletons dissolve away as CO_2 levels rise.
