多样性-干扰关系在生态学、生物多样性保护和生物多样性管理中有着广泛的应用。尽管它们具有解释力,但这些概念框架尚未被系统地应用于理解不同微生物生物膜中的演替。在这里,我们使用与数百个操作分类单位(OTU)相对应的群落16S rRNA基因的时间历程测序,研究了在复制微生物生物电化学系统中形成的生物膜中的群落组装。我们首次提出了一个统计模型,表明一个简单的多样性-干扰关系可以用来解释高多样性生物膜群落的动态变化。这个简单的模型表明,这些系统的演替要么被引导到低多样性、通才主导的生物膜,要么被引导到高多样性、合作专家的生物膜,这取决于群落内测量的内生干扰水平。观察到的模式与草原、森林和珊瑚礁等大尺度群落的发现显示出显著的对称性。
Diversity-disturbance relationships have found widespread application in ecology, conservation and biodiversity management. In spite of their explanatory power, these conceptual frameworks have yet to be systematically applied to understanding succession in diverse microbial biofilms. Here we investigate community assembly in biofilms formed in replicate microbial bioelectrochemical systems using time-course sequencing of community 16S rRNA genes, corresponding to hundreds of operational taxonomic units (OTUs). For the first time we present a statistical model showing that a simple diversity-disturbance relationship can be used to explain dynamic changes in high diversity biofilm communities. This simple model reveals that succession in these systems is guided towards either a low diversity, generalist-dominated biofilm or a high diversity, cooperative-specialist biofilm, depending on the level of endogenous disturbance measured within the community. The pattern observed shows remarkable symmetry with findings from macro-scale communities such as grasslands, forests and coral reefs.
