AbstractThe SEED project was designed to increase our understanding of the extent to which environmental and physiological factors influence the non-vegetative life history stages of harmful algal species and the transitions between these and other stages, thereby contributing to the dynamics of harmful algal blooms (HABs) in marine, fresh, and brackish waters. The project focused on the life histories of some of the most important HAB species including freshwater (Raphidophyceae); estuarine (Cyanophyceae) and marine (Dinophyceae and Bacillariophyceae) examples and drawing on a wide range of locations (Western Mediterranean, Atlantic Ocean, North Sea, Baltic Sea and Swedish Lakes). All of these regions have heavy anthropogenic influences: fisheries, urban development, aquaculture and tourism, and are subject to the frequent occurrence of HABs, with a variety of detrimental impacts. SEED demonstrated that harmful algal events are widely divergent with regard to the life cycle mechanisms involved, and that the life cycles of several congeneric species show unexpected complexities. In this presentation, attention will be placed on singular and common patterns of response among species, the impact that life cycles have on the ecology of bloom events for a range of phylogenetic types, and the development of conceptual and numerical models of cyst-or spore-forming HAB species in coastal systems
