Plants connect both pollinators and herbivores, and motivate the exploration of community structure in ecological networks merging antagonistic and mutualistic interactions. Evidence has shown that the two opposite plant-animal interactions are not independent from each other, in particular, herbivores can affect plant-pollinator pairwise interactions. Here, we explored effects of herbivore-induced pollinator limitation on community stability (including temporal stability and composition stability) of the mutualism-antagonism continuum. Our model demonstrated that pollinator limitation can boost up both temporal stability (i.e., the proportion of stable communities) and composition stability (i.e., species persistence), while the positive effects also depend on the strength of antagonistic and mutualistic interactions. Specifically, a community with higher temporal stability has a higher composition stability. Meanwhile, the correlations between network architecture and composition stability are also affected by pollinator limitation. Therefore, our results highlight that pollinator limitation can enhance community stability and may alter network architecture-composition stability relationship, and further advance the interplay between multiple types of species interactions within ecological networks.
植物连接传粉者和食草动物，并促使人们探索合并了对抗性和互利性相互作用的生态网络中的群落结构。有证据表明，这两种相反的植物-动物相互作用并非相互独立，特别是食草动物会影响植物-传粉者的成对相互作用。在这里，我们探索了食草动物诱导的传粉者限制对互利共生-对抗连续体群落稳定性（包括时间稳定性和组成稳定性）的影响。我们的模型表明，传粉者限制可以提高时间稳定性（即稳定群落的比例）和组成稳定性（即物种持久性），而积极的影响也取决于对抗性和互利性相互作用的强度。具体来说，具有更高时间稳定性的群落具有更高的组成稳定性。同时，网络结构与组成稳定性之间的相关性也受到传粉者限制的影响。因此，我们的结果强调了传粉者限制可以增强群落稳定性，并可能改变网络结构-组成稳定性关系，进一步促进生态网络中多种类型物种相互作用之间的相互作用。
