共生关系是多物种群落的基本组成部分，在生态系统的功能中起着至关重要的作用。然而，早期的互惠理论预测，互惠互动可能会破坏稳定，因为互惠者相互依赖的增加导致了他们的人口爆炸。后来的研究表明，其他因素，如互惠互利的成本或饱和收益，以及利用互惠互利的对抗性相互作用，可能会抑制互惠互利的不稳定效应。在植物-传粉者的共生关系中，对传粉者的捕食是一种常见的拮抗相互作用形式，尽管其对植物-传粉者共生关系稳定性的影响仍然知之甚少。在这里，我们使用一个数学模型，考虑捕食传粉者是否可以稳定植物-传粉者的相互关系。研究表明，对传粉者的捕食并不能稳定本就不稳定的植物-传粉者共生关系，但传粉者为了避免捕食而改变行为可以稳定共生关系。我们的研究结果有助于更好地理解捕食者诱导的传粉者行为改变如何影响植物-传粉者相互关系的维持。
Mutualisms are a basic component of multispecies communities and play crucial roles in the functioning of ecosystems. Early theory on mutualisms, however, predicted that mutualistic interactions could be destabilizing because the interdependent augmentation of mutualists caused their population explosion. Later studies suggested that additional factors, such as costs or saturating benefits of mutualisms and antagonistic interactions that exploited mutualisms, could dampen the destabilizing effect of mutualisms. In plant–pollinator mutualisms, predation on pollinators is a common form of antagonistic interactions, although its effects on the stability of plant–pollinator mutualisms have remained poorly understood. Here, using a mathematical model, we consider whether predation on pollinators can stabilize plant–pollinator mutualisms. We show that predation on pollinators does not stabilize an inherently unstable plant–pollinator mutualism, but the modification of pollinator behavior to avoid predation can stabilize the mutualism. Our results contribute to a better understanding of how predator‐induced behavior modification in pollinators can affect the maintenance of plant–pollinator mutualisms.
