The dinoflagellate genus Alexandrium is one of the major harmful algal bloom
(HAB) genera with respect to the diversity, magnitude and consequences of blooms. The
ability of Alexandrium to colonize multiple habitats and to persist over large regions
through time is testimony to the adaptability and resilience of this group of species. Three
different families of toxins, as well as an as yet incompletely characterized suite of
allelochemicals are produced among Alexandrium species. Nutritional strategies are
equally diverse, including the ability to utilize a range of inorganic and organic nutrient
sources, and feeding by ingestion of other organisms. Many Alexandrium species have
complex life histories that include sexuality and often, but not always, cyst formation,
which is characteristic of a meroplanktonic life strategy and offers considerable
ecological advantages. Due to the public health and ecosystem impacts of Alexandrium
blooms, the genus has been extensively studied, and there exists a broad knowledge base
that ranges from taxonomy and phylogeny through genomics and toxin biosynthesis to
bloom dynamics and modeling. Here we present a review of the genus Alexandrium,
focusing on the major toxic and otherwise harmful species.
