微生物可以入侵整个群落，但对整个群落入侵的生态学了解甚少。在这里，我们调查了入侵繁殖压力(入侵生物体的数量)如何影响入侵的实验室产甲烷群落的组成和功能。入侵群落在居民社区中的建立同样成功，而不受繁殖压力的影响，传播压力在居民社区大小的0.01-10%之间变化。入侵导致沼气产量增加(达到纯入侵群落的水平)，但仅当繁殖压力为1%或更大时。入侵成功和功能变化之间的这种不一致可以用较低繁殖压力下入侵类群的较低丰富度和缺乏的类群的重要功能作用来解释。我们的结果强调，整个群落入侵生态不能简单地从我们对单一物种入侵的理解中推断出来。此外，我们还表明，通过入侵性能较差的反应堆和性能较好的社区，可以提高甲烷产量，这在工业环境中可能是可行的。复杂群落可以成功地入侵其他群落，入侵改变群落组成不受繁殖压力的影响，入侵的类群数量随着繁殖压力的增加而增加，较大的繁殖压力对群落结构和功能都有影响生态学；微生物学；应用微生物学；
Microbes can invade as whole communities, but the ecology of whole community invasions is poorly understood. Here, we investigate how invader propagule pressure (the number of invading organisms) affects the composition and function of invaded laboratory methanogenic communities. An invading community was equally successful at establishing itself in a resident community regardless of propagule pressure, which varied between 0.01 and 10% of the size resident community. Invasion resulted in enhanced biogas production (to the level of the pure invading community) but only when propagule pressure was 1% or greater. This inconsistency between invasion success and changes in function can be explained by a lower richness of invading taxa at lower propagule pressures, and an important functional role of the taxa that were absent. Our results highlight that whole community invasion ecology cannot simply be extrapolated from our understanding of single species invasions. Moreover, we show that methane production can be enhanced by invading poorly performing reactors with a better performing community at levels that may be practical in industrial settings. Complex communities can successfully invade other communities Invasions change the community composition independently of propagule pressure Number of taxa invading increases with increased propagule pressure Larger propagule pressure impacts both the community structure and function Ecology; Microbiology; Applied microbiology;
