生态学家长期以来一直在研究植物和动物群落的时间动态，而很少关注微生物群落所表现出的时间动态。因此，我们不知道微生物群落是否存在总体的时间趋势，或者微生物群落的变化是否可以随着时间的推移而普遍预测。利用高通量测序评估的微生物时间序列，我们对微生物群落的时间动态进行了荟萃分析，包括76个代表空气、水生、土壤、啤酒废水处理、人类和植物相关微生物群落的地点。我们发现，在相似环境的微生物群落中，群落内和群落间多样性的时间变异性是一致的。在不到一半的病例中，社区结构随时间发生了系统性变化，在所有被调查的社区中，在1天至1个月的范围内观察到最高的变化率。微生物群落表现出物种-时间关系（STRs），这种关系描述了一个群落中新分类群的积累，类似于以前在植物和动物群落中观察到的，表明STRs在广泛的分类群中是非常一致的。这些结果强调，微生物生态学与更广泛的生态学领域的持续整合将为微生物和“宏观”生物群落的时间模式提供新的见解。
Ecologists have long studied the temporal dynamics of plant and animal communities with much less attention paid to the temporal dynamics exhibited by microbial communities. As a result, we do not know if overarching temporal trends exist for microbial communities or if changes in microbial communities are generally predictable with time. Using microbial time series assessed via high-throughput sequencing, we conducted a meta-analysis of temporal dynamics in microbial communities, including 76 sites representing air, aquatic, soil, brewery wastewater treatment, human- and plant-associated microbial biomes. We found that temporal variability in both within- and between-community diversity was consistent among microbial communities from similar environments. Community structure changed systematically with time in less than half of the cases, and the highest rates of change were observed within ranges of 1 day to 1 month for all communities examined. Microbial communities exhibited species–time relationships (STRs), which describe the accumulation of new taxa to a community, similar to those observed previously for plant and animal communities, suggesting that STRs are remarkably consistent across a broad range of taxa. These results highlight that a continued integration of microbial ecology into the broader field of ecology will provide new insight into the temporal patterns of microbial and ‘macro'-bial communities alike.
