“…Many studies have proven a high variability of various traits among different strains or isolates of microalgae species even within the same local population (Maranda et al, 1985;Costas, 1990;Orlova et al, 2007;Tillmann et al, 2009;Alpermann et al, 2010). This is important to keep in mind when discussing differences between species for any ecophysiological trait, as interspecific differences can only be evaluated when the range of intraspecific variability for a given species is known.…”

“…With the production of new and brighter fluorochromes and further enhancements of species-specific cell sorting and separating, species-specific physiological data may be obtained rapidly and more reliably than with methods used currently. (Maranda et al 1985;Anderson 1989), and many other coastal regions of the world . PSP occurs when shellfish accumulate the dinoflagellate toxins during feeding and pass the potent neurotoxins on to humans.…”

“…This retention mechanism not only restricts the extent to which cells and cysts can colonize adjacent waters, but it allows Alexandrium populations to accumulate to levels where toxicity becomes dangerous. This is a particularly important feature, as the toxicity of the Alexundrium populations in the southern salt ponds and embayments is lower than the coastal populations to the north (Maranda et al 1985;Anderson et al 1994).…”

Coastal waters of the northeastern U.S. are subject to rccurrcnt outbreaks of paralytic shclllish 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 discontinuous distribution of the dinollagellatcs. Each of these habitats has a unique set of environmental and oceanographic forcings that dcterminc the timing and extent of bloom development and transport and that regulate the extent of genetic cxchangc with adjacent populations. Several habitats (e.g. the southwcstcrn Gulf of Maine, Massachusetts Bay, and Georges Bank) arc linked hydrographically and may share the same Alexandrium population via large-scale transport in a coastal current, whereas the other two habitats (eastern Maine and southern salt ponds-embaymcnts) seem to be isolated and have little or no hydrographic or genetic linkage to adjacent regions during bloom seasons. My paper provides an overview of the regional ecology and oceanography of Alenandrium through a focus on these hvc subpopulations. Issues that relate to PSP and AZenandrium dynamics throughout the world are highlighted, including species dispersal, the role of cysts and "initiation zones" in bloom dcvclopment, and the influence of large-and small-scale hydrography on population development and transport. The ability of Alexandrium to colonize multiple habitats and to persist over a large region is emphasized in recognition of the adaptability and resilience of this important organism.In many parts of the world, paralytic shellfish poisoning (PSP) is a recurrent and serious problem associated with blooms of toxic dinoflagellates in the genus Akxandrium. The potent neurotoxins produced by these organisms are accumulated by filter-Feeding shellfish and other grazers and are passed on to humans and other animals at higher trophic levels, leading to illness, incapacitation, and even death. AZexandrium causes toxicity in many different hydrographic and climatic regimes, from temperate to tropical (e.g. Cembella et al. 1988; La Barbera-Sanchez et al. 1993). This ecological distribution reflects a genetic diversity that is far more extensive than simple morphology might imply. Scholin et al. (1994Scholin et al. ( , 1995 clearly demonstrated that even though a single morphospecies such as Alexandrium tamarense can be found in widely different geographic zones, isolates from those different regions have unique genotypes based on ribosomal RNA sequences.
