Abstract

Dendritic stream networks are an intriguing subject for exploring the spatial and temporal variability of the rare and common bacterial biosphere, yet very few such studies have been conducted. We sampled riverine bacterioplankton at 13 sites in a subarctic riverine network across 3 years, with five sampling times each year. Ordinations showed a consistent pattern of downstream shift for both rare and abundant subcommunities. We also detected a temporal signal, with seasonal community shifts reflecting changes in water temperature and groundwater contribution, and an inter-annual pattern where the year 2018 differed from other years. Phylogenetic turnover of the rare subcommunity indicated homogeneous selection, whereas the abundant subcommunity was mainly stochastically structured. Transiently rare taxa were the dominant type of rarity with the highest proportion at the headwater regions. The bacterioplankton community was characterized by a small group of core taxa that occurred at most sites with little temporal variation, a very large number of permanently or transiently rare taxa, and taxa shifting through time between the rare and abundant biosphere. While this basic structure could have been detected with less extensive temporal replication, a comprehensive understanding of the rare biosphere in riverine bacterioplankton can only be achieved via inter-annual, spatially replicated sampling that covers the whole stream network.

亚北极溪流网络中的细菌稀有性:生物多样性模式、组装机制和稀有类型。
树枝状河流网络是探索稀有和常见细菌生物圈时空变异性的一个有趣课题,但此类研究却寥寥无几。我们在亚北极河网的 13 个地点对河流浮游细菌进行了为期 3 年的采样,每年采样 5 次。结果表明,稀有和丰富的亚群落都有一致的向下游移动的模式。我们还发现了一个时间信号,即群落的季节性变化反映了水温和地下水贡献的变化,以及 2018 年不同于其他年份的年际模式。稀有亚群落的系统发生更替表明存在同质选择,而丰富亚群落主要是随机结构。瞬时稀有类群是稀有性的主要类型,在上游地区所占比例最高。浮游细菌群落的特点是:一小群核心类群出现在大多数地点,几乎没有时间变化;大量类群永久或短暂稀有;类群在稀有和丰富生物圈之间随时间变化。虽然这种基本结构可以通过较少的时间复制来发现,但只有通过覆盖整个溪流网络的跨年度、空间复制采样,才能全面了解河流浮游细菌的稀有生物圈。
