Recently, conditionally rare taxa (CRTs)--those taxa that are typically in very low abundance but occasionally achieve prevalence--were shown to contribute to patterns of microbial diversity because their collective dynamics explained a large proportion of temporal variability in microbial community structure. Here the benefits and challenges of characterizing the presence and interpreting the role of CRTs are further explored, along with questions about CRT ecology. We also introduce a conceptual model for thinking about microbial taxa as dynamic components along the dimensions of occurrence and abundance. Accounting for CRTs in interpretations of microbial ecological dynamics is essential if we are to understand community stability and ecoevolutionary interactions.
最近，条件稀有分类群（CRTs）——那些通常在非常低的丰度下但偶尔达到流行度的分类群——被证明对微生物多样性模式有贡献，因为它们的集体动态解释了微生物群落结构时间变化的很大一部分。在这里，进一步探讨了描述 CRT 的存在和解释其作用的益处和挑战，以及关于 CRT 生态学的问题。我们还引入了一个概念模型，用于将微生物分类群视为沿着出现和丰度维度的动态组成部分。如果我们要理解群落稳定性和生态进化相互作用，那么在解释微生物生态动态时考虑 CRT 是必不可少的。
