摘要

Coastal waters of the northeastern U.S. are subject to recurrent outbreaks of paralytic shellfish poisoning (PSP) caused by toxic dinoflagellates in the genus Alexandrium. PSP is not uniform across the large region, but instead reflects Alexandrium growth and toxin accumulation in five separate habitats or zones defined by circulation patterns and the disocntinuous distribution of the dinofagellates. Each of these habitats has a unique set of environmental and oceanoraphic forcings that determine the timing and extent of bloom development and transport and that regulate the extent of genetic exchange with adjacent populations.
