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.
多种全球性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种群或群落流行病出现的风险。花朵是病原体传播的中心。因此，植物-传粉者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方面起着关键作用。植物、传粉者和病原体的特征也可能控制病原体的种间传播。在管理和野生传粉者之间发生病原体溢出-回溢，有可能导致毒力进化和群落流行病。理解宿主-病原体动态与全球变化之间的这种相互作用对于预测对授粉者以及授粉支持的生态系统和人类福祉的影响至关重要。
