Multiple global change pressures, and their interplay, cause plant–pollinator extinctions and modify species assemblages and interactions. This may alter the risks of pathogen host shifts, intra- or interspecific pathogen spread, and emergence of novel population or community epidemics. Flowers are hubs for pathogen transmission. Consequently, the structure of plant–pollinator interaction networks may be pivotal in pathogen host shifts and modulating disease dynamics. Traits of plants, pollinators, and pathogens may also govern the interspecific spread of pathogens. Pathogen spillover–spillback between managed and wild pollinators risks driving the evolution of virulence and community epidemics. Understanding this interplay between host–pathogen dynamics and global change will be crucial to predicting impacts on pollinators and pollination underpinning ecosystems and human wellbeing.

多种全球变化压力及其相互作用导致植物 - 传粉者灭绝并改变物种组合和相互作用。这可能会改变病原体宿主转移、种内或种间病原体传播以及新人群或社区流行病出现的风险。花是病原体传播的枢纽。因此，植物 - 传粉媒介相互作用网络的结构可能在病原体宿主转移和调节疾病动态中起关键作用。植物、传粉媒介和病原体的特征也可能控制病原体的种间传播。受管理的传粉媒介和野生传粉媒介之间的病原体外溢-外溢可能会推动毒力和社区流行病的演变。
