微生物参与生态群落，就像多细胞生物一样。然而，微生物群落缺乏几个世纪的观察和理论描述和预测多细胞生物可用的生态过程。在这里，我们研究早期的细菌群落组装在充满水的亚马逊竹属Guadua的节间。竹林在低地亚马逊雨林中形成了独特的栖息地，为一系列脊椎动物和无脊椎动物提供了栖息地。瓜杜竹在生长过程中会形成封闭的、充满水的节间。节间被认为是无菌的或接近无菌的，而关闭，但大多数最终开放的环境中的动物，之后他们被微生物殖民。我们发现，微生物群落的多样性急剧增加，在最初几天的环境暴露，和分类身份的微生物的变化，通过这段时间的预测，在宏观社区的早期社区组装。微生物群落分类周转率在细菌门水平上是一致的，但在操作分类单位（OTU）水平上，节间群落随着时间的推移变得越来越分化。我们认为，这些热带竹子形成了一个理想的微生物群落生态学的研究系统，由于其开放前的近无菌条件，开放后相对一致的环境，并在功能上无限的可能性复制。考虑到开放的节间栖息地作为动物间致病微生物和有益微生物的传播场所的可能重要性，了解节间栖息地的微生物动力学是使用此微栖息地的昆虫和两栖动物物种的关键保护问题。
Microbes participate in ecological communities, much like multicellular organisms. However, microbial communities lack the centuries of observation and theory describing and predicting ecological processes available for multicellular organisms. Here, we examine early bacterial community assembly in the water-filled internodes of Amazonian bamboos from the genus Guadua. Bamboo stands form distinct habitat patches within the lowland Amazonian rainforest and provide habitat for a suite of vertebrate and invertebrate species. Guadua bamboos develop sealed, water-filled internodes as they grow. Internodes are presumed sterile or near sterile while closed, but most are eventually opened to the environment by animals, after which they are colonized by microbes. We find that microbial community diversity increases sharply over the first few days of environmental exposure, and taxonomic identity of the microbes changes through this time period as is predicted for early community assembly in macroscopic communities. Microbial community taxonomic turnover is consistent at the bacteria phylum level, but at the level of Operational Taxonomic Units (OTUs), internode communities become increasingly differentiated through time. We argue that these tropical bamboos form an ideal study system for microbial community ecology due to their near-sterile condition prior to opening, relatively consistent environment after opening, and functionally limitless possibilities for replicates. Given the possible importance of opened internode habitats as locations of transmission for both pathogenic and beneficial microbes among animals, understanding the microbial dynamics of the internode habitat is a key conservation concern for the insect and amphibian species that use this microhabitat.
