实验证明，许多产藻微藻，包括蓝细菌、甲藻、附着菌、针鞭菌和硅藻等物种的生活史性状、行为、营养、遗传和毒性等关键特征存在种内变异（株系差异）。本文总结了已发表的关于种内毒性变异性的研究结果。数据表明，考虑到个别菌株，在物种一级可能会产生不同的、往往是相反的解释。对有害藻类最近文献的调查显示，在这些物种的特征和概括它们在食物网中的作用时，种内变异仍然被普遍忽视。现有数据强调了在研究中包括多个菌株以促进对产藻藻类物种的了解的重要性，以及调和结论以考虑所研究菌株之外的差异的重要性。
Intraspecific variability (strain differences) in key characteristics such as life-history traits, behaviour, nutrition, genetics and toxicity, has been experimentally documented for many toxigenic microalgae, including species of cyanobacteria, dinoflagellates, haptophytes, raphidophytes and diatoms. This paper summarises findings from published studies on intraspecific variability in toxicity. The data show that different, often opposite, interpretations at the species level would have resulted from consideration of individual strains. A survey of recent literature on harmful algae revealed that intraspecific variation is still commonly overlooked in characterisations of these species and generalisations about their roles in foodwebs. The available data underscore the importance of including multiple strains in research to advance understanding about toxigenic algal species and the importance of tempering conclusions to consider the potential for differences beyond the strains studied.
