Despite the ubiquity of pathogens in ecological systems, their roles in influencing ecosystem services are often overlooked. Pathogens that infect primary producers (i.e., plants, algae, cyanobacteria) can have particularly strong effects because autotrophs are responsible for a wide range of provisioning, regulating, and cultural services. We review the roles of pathogens in mediating ecosystem services provided by autotrophs and outline scenarios in which infection may lead to unexpected outcomes in response to global change. Our synthesis highlights a deficit of information on this topic, and we outline a vision for future research that includes integrative theory and cross-system empirical studies. Ultimately, knowledge about the mediating roles of pathogens on ecosystem services should inform environmental policy and practice.

尽管病原体在生态系统中无处不在，但它们在影响生态系统服务中的作用常常被忽视。感染初级生产者（例如，植物，藻类，蓝细菌）的病原体可能具有特别强的作用，因为自养生物负责广泛的供应，调节和文化服务。我们回顾了病原体在介导自养生物提供的生态系统服务中的作用，并概述了在感染可能导致响应全球变化的意外结果的情况。我们的综合突出显示了有关此主题的信息不足，并且我们概述了包括集成理论和跨系统实证研究在内的未来研究愿景。最终，有关病原体在生态系统服务中的中介作用的知识应为环境政策和实践提供参考。
