Since the establishment of GEOHAB, our knowledge of harmful algal blooms has evolved. However, while general concepts and paradigms continue to guide our investigations they often fail to consider the multifaceted aspects of blooms and the producing organisms, especially the complexities of the biological traits of several congeneric species. Precise characterizations and more focused research efforts are needed to close the remaining gaps in our understanding of species. Here, we summarize the lessons learned from species-specific studies, carried out by our group over the last several decades, of near-shore microalgal blooms. Data acquired from research and monitoring programs greatly enhanced our knowledge of species composition, the conditions that trigger bloom events and those that determine both their recurrence and their intensity. Our own efforts consisted of: i) descriptions of new species; ii) firsttime detections in the investigated areas; iii) blooms of rare species; iv) the identification of introduced species; and v) insights into species dispersal mechanisms. Most importantly, our studies opened up novel areas of research, focusing on previously unrecognized life-cycle pathways and the reversibility of the sexual stage in dinoflagellates. Thus, new paradigms of bloom dynamics are conceivable, e.g., the formation and maintenance of small-scale coastal blooms despite physical constrains. Accordingly, interpretations of bloom dynamics, persistence, and recurrence require a renewed examination of the biological behaviors of organisms and their environmental interactions, based on detailed taxonomy and appropriately scaled studies of growth rates, life cycles, and adaptive strategies, in an approach that distinguishes between broad concepts and species-specific characteristics
