摘要

A team of researchers in the U.S. and Spain announced in February the discovery of the mechanism that triggers phytoplankton toxin release. These highly potent toxins are part of red tide formations, which are made of phytoplankton blooms that kill millions of sea creatures in coastal waters around the world. The causes of red tides remain unknown.Algae, such as Karenia brevis, that proliferate and compile on the ocean's surface appear as a red tide. Karenia is a unicellular microalgae deadly to marine life and hazardous to human health because it produces brevetoxin, a neurotoxin that binds to nerve and muscle cells. The precise causes of algal blooms are still a mystery that has to do with fluctuations in ocean temperature, salinity and nutrients.
