Natural Sciences and Engineering Research Council of Canada Aquatic bacterial communities Boreal lakes Abundance distributions Temporal-spatial relationship Temporal recruitment Mass effects Environmental sorting Rare biosphere 12 pages, 4 figures, 1 table, supplementary material http://journal.frontiersin.org/article/10.3389/fmicb.2017.00636/full#supplementary-material One of the major contemporary challenges in microbial ecology has been to discriminate the reactive core from the random, unreactive components of bacterial communities. In previous work we used the spatial abundance distributions of bacterioplankton across boreal lakes of Québec to group taxa into four distinct categories that reflect either hydrology-mediated dispersal along the aquatic network or environmental selection mechanisms within lakes. Here, we test whether this categorization derived from the spatial distribution of taxa is maintained over time, by analyzing the temporal dynamics of the operational taxonomic units (OTUs) within those spatially derived categories along an annual cycle in the oligotrophic lake Croche (Québec, Canada), and assessing the coherence in the patterns of abundance, occurrence, and environmental range of these OTUs over space and time. We report that the temporal dynamics of most taxa within a single lake are largely coherent with those derived from their spatial distribution over large spatial scales, suggesting that these properties must be intrinsic of particular taxa. We also identified a set of rare taxa cataloged as having a random occupancy based on their spatial distribution, but which showed clear seasonality and abundance peaks along the year, yet these comprised a very small fraction of the total rare OTUs. We conclude that the presence of most rare bacterioplankton taxa in boreal lakes is random, since both their temporal and spatial dynamics suggest links to passive downstream transport and persistence in freshwater networks, rather than environmental selection his study is part of the program of the Carbon Biogeochemistry in Boreal Aquatic Systems (CarBBAS) Industrial Research Chair, co-funded by the Natural Science and Engineering Research Council of Canada (NSERC) and Hydro-Quebec Peer Reviewed 2017-06-19T06:47:28Z 2017-06-19T06:47:28Z 2017-04 2017-06-19T06:47:29Z artículo http://purl.org/coar/resource_type/c_6501 doi: 10.3389/fmicb.2017.00636 e-issn: 1664-302X Frontiers in Microbiology 8: 636 (2017) http://hdl.handle.net/10261/151594 10.3389/fmicb.2017.00636 http://dx.doi.org/10.13039/501100000038 28484431 Publisher's version https://dx.doi.org/10.3389/fmicb.2017.00636 Sí open Frontiers Media |
