What Causes Algal Blooms to Become Toxic?

The disastrous 2015-16 Dungeness crab season, delayed and shortened by an unprecedented bloom of toxic algae, is a bitter memory for the West Coast fishing industry. The culprit was domoic acid, a potent neurotoxin produced by marine algae and discovered in 1987 as the cause of amnesic shellfish poisoning. Scientists at UC Santa Cruz have […]

Marine Invasive Species Benefiting from Rising Carbon Dioxide Levels

Ocean acidification may well be helping invasive species of algae, jellyfish, crabs and shellfish to move to new areas of the planet with damaging consequences, according to the findings of a new report. Slimy, jelly-like creatures are far more tolerant of rising carbon dioxide levels than those with hard structures like corals, since exposed shells […]
