Although spatial and temporal variation are both important components structuring microbial communities, the exact quantification of temporal turnover rates of fungi and bacteria has not been performed to date. In this study, we utilised repeated resampling of bacterial and fungal communities at specific locations across multiple years to describe their patterns and rates of temporal turnover. Our results show that microbial communities undergo temporal change at a rate of 0.010–0.025 per year (in units of Sorensen similarity), and the change in soil is slightly faster in fungi than in bacteria, with bacterial communities changing more rapidly in litter than soil. Importantly, temporal development differs across fungal guilds and bacterial phyla with different ecologies. While some microbial guilds show consistent responses across regional locations, others show site-specific development with weak general patterns. These results indicate that guild-level resolution is important for understanding microbial community assembly, dynamics and responses to environmental factors.

土壤微生物组组成的时间更替是特定于公会的

尽管空间和时间变化都是构建微生物群落的重要组成部分,但迄今为止尚未对真菌和细菌的时间更新率进行精确量化。在这项研究中,我们利用多年来在特定位置重复重新采样细菌和真菌群落来描述它们的模式和时间更新率。我们的结果表明,微生物群落以每年 0.010-0.025 的速度发生时间变化(以 Sorensen 相似度为单位),土壤中真菌的变化略快于细菌,凋落物中的细菌群落比土壤中的变化更快. 重要的是,不同生态系统的真菌群和细菌门的时间发展不同。虽然一些微生物行会在不同地区表现出一致的反应,但其他人则表现出具有弱一般模式的特定地点发展。这些结果表明,行会级别的分辨率对于理解微生物群落组装、动态和对环境因素的响应很重要。
