Biological invasions impact both agricultural and natural systems. The damage can be quantified in terms of both economic loss and reduction of biodiversity. Although the literature is quite rich about the impact of invasive species on plant and animal communities, their impact on environmental microbiomes is underexplored. Here, we re-analyze publicly available data using a common framework to create a global synthesis of the effects of biological invasions on environmental microbial communities. Our findings suggest that non-native species are responsible for the loss of microbial diversity and shifts in the structure of microbial populations. Therefore, the impact of biological invasions on native ecosystems might be more pervasive than previously thought, influencing both macro- and micro-biomes. We also identified gaps in the literature which encourage research on a wider variety of environments and invaders, and the influence of invaders across seasons and geographical ranges.
生物入侵既影响农业系统也影响自然系统。其造成的破坏既可以用经济损失来衡量，也可以用生物多样性的减少来衡量。尽管关于入侵物种对动植物群落的影响，文献资料相当丰富，但它们对环境微生物组的影响却还没有得到充分的研究。在这里，我们使用通用框架重新分析了公开可用的数据，对生物入侵对环境微生物群落的影响进行了全球综合分析。我们的研究结果表明，非本地物种是造成微生物多样性丧失和微生物种群结构变化的原因。因此，生物入侵对本地生态系统的影响可能比以前认为的更为普遍，既影响宏观生物群也影响微观生物群。我们还发现了文献中的空白，鼓励对更广泛的环境和入侵物种进行研究，并研究入侵物种在不同季节和地理范围内的影响。
