摘　　要：建立了一类在食草动物诱导下传粉功能限制及其调控下的传粉昆虫-植物互惠群落模型.同时,考虑了传粉昆虫的适应性觅食策略.依据所构建的适应性网络模型,探讨了捕食压力如何影响互惠网络的结构,稳定性和功能.结果表明,食草动物的捕食压力会使适应性优化网络的嵌套性增加,而群落稳定性、续存概率与多样性降低.食草动物-植物间的拮抗作用对适应性互惠网络的结构和稳定性起着至关重要的作用.This paper establishes a model for a pollinator-plant mutualistic community under the regulation of pollination function limitation induced by herbivores.Additionally,the adaptive foraging strategy of pollinators is considered.Based on the constructed adaptive network model,we explore how predation pressure affects the structure,stability,and functionality of mutualistic networks.The results indicate that predation pressure from herbivores increases the nestedness of adaptive networks,while community stability,persistence probability,and diversity decrease.In summary,the antagonistic interactions between herbivores and plants play a crucial role in the structure and stability of adaptive mutualistic networks.
