营养不良，或生物体对外源有机分子的需求，在物种和生态系统中广泛存在。营养不良会导致生物之间的强制性相互作用，影响生态系统结构和群落组成。我们探讨营养不良诱导的水生微生物之间的相互作用如何影响微生物群落的结构和稳定性。虽然一些研究记录了水生微生物的营养不良，但这些研究并不广泛，因此我们不知道水生环境中营养不良相互作用的全部程度。目前的理论和实验工作表明，营养不良通过一个复杂的代谢依赖网络将微生物群落成员联系起来。我们讨论了营养不良可能增强或破坏水生微生物群落稳定性的拟议方式，强调了我们对这些相互作用的有限理解使我们无法预测营养不良的生态影响的领域。最后，我们研究了有害藻华中营养不良的一个例子，将这种通常的理论讨论置于一个可能对藻华群落的发展和健壮性有影响的实地背景下。我们试图引起人们对营养不良和群落稳定性之间关系的关注，以鼓励进一步的实地和理论工作，探索微生物相互作用的潜在原理。讨论营养不良（生物体对有机微量营养素的需求）在环境变化时对水生微生物群落稳定性的潜在影响。
Auxotrophy, or an organism's requirement for an exogenous source of an organic molecule, is widespread throughout species and ecosystems. Auxotrophy can result in obligate interactions between organisms, influencing ecosystem structure and community composition. We explore how auxotrophy-induced interactions between aquatic microorganisms affect microbial community structure and stability. While some studies have documented auxotrophy in aquatic microorganisms, these studies are not widespread, and we therefore do not know the full extent of auxotrophic interactions in aquatic environments. Current theoretical and experimental work suggests that auxotrophy links microbial community members through a complex web of metabolic dependencies. We discuss the proposed ways in which auxotrophy may enhance or undermine the stability of aquatic microbial communities, highlighting areas where our limited understanding of these interactions prevents us from being able to predict the ecological implications of auxotrophy. Finally, we examine an example of auxotrophy in harmful algal blooms to place this often theoretical discussion in a field context where auxotrophy may have implications for the development and robustness of algal bloom communities. We seek to draw attention to the relationship between auxotrophy and community stability in an effort to encourage further field and theoretical work that explores the underlying principles of microbial interactions. Discussion of the potential impact of auxotrophy, the requirement by an organism for an organic micronutrient, on the stability of aquatic microbial communities in the face of environmental changes.
