Invasions by eukaryotes dependent on environmentally acquired bacterial mutualists are often limited by the ability of bacterial partners to survive and establish free-living populations. Focusing on the model legume-rhizobium mutualism, we apply invasion biology hypotheses to explain how bacteriophages can impact the competitiveness of introduced bacterial mutualists. Predicting how phage-bacteria interactions affect invading eukaryotic hosts requires knowing the eco-evolutionary constraints of introduced and native microbial communities, as well as their differences in abundance and diversity. By synthesizing research from invasion biology, as well as bacterial, viral, and community ecology, we create a conceptual framework for understanding and predicting how phages can affect biological invasions through their effects on bacterial mutualists.
真核生物的入侵往往取决于环境中获得的细菌共生体的生存和建立自由生活种群的能力。本文以模式豆科植物-根瘤菌共生关系为重点，应用入侵生物学假说来解释噬菌体如何影响引入的细菌共生体的竞争力。预测噬菌体-细菌相互作用如何影响入侵的真核宿主，需要了解引入和本地微生物群落的生态进化限制，以及它们在丰度和多样性方面的差异。通过综合入侵生物学、细菌学、病毒学和群落生态学的研究，我们创建了一个概念框架，用于理解和预测噬菌体如何通过其对细菌共生体的影响来影响生物入侵。
