劳伦特五大湖为数百万人提供经济支持,推动地球化学循环,是表征水生生态系统基本组成部分的重要天然实验室。小型浮游植物是劳伦特五大湖食物网的重要组成部分。在这里,第一次,我们揭示和量化八个表型不同的picophytoplankton人口在整个湖泊使用多激光流式细胞术的方法,区分细胞的基础上,他们的色素表型。微微型浮游植物流种群的分布和多样性各不相同的湖泊和深度,与伊利湖站出来的最高的多样性。通过对分选的细胞进行测序,我们确定了几个不同的集胞菌谱系,跨越亚群5.2和5.3。不同的基因型簇映射到表型相似的流动群体,这表明基因型和表型之间可能没有明确的一对一映射。这表明湖泊之间的基因组水平分化,但在色素特征方面存在一定程度的表型趋同。我们的研究结果表明,生态选择当地适应人口的速度可能会超过同质化的物理运输在这个相互关联的系统。鉴于五大湖依赖于原地初级生产作为有机碳的来源,这项工作奠定了基础,以测试小型初级生产者的社区结构如何对应于五大湖和其他淡水系统的地球化学和食物网功能。
The Laurentian Great Lakes provide economic support to millions of people, drive biogeochemical cycling, and are an important natural laboratory for characterizing the fundamental components of aquatic ecosystems. Small phytoplankton are important contributors to the food web in much of the Laurentian Great Lakes. Here, for the first time, we reveal and quantify eight phenotypically distinct picophytoplankton populations across the Lakes using a multilaser flow cytometry approach, which distinguishes cells based on their pigment phenotype. The distributions and diversity of picophytoplankton flow populations varied across lakes and depths, with Lake Erie standing out with the highest diversity. By sequencing sorted cells, we identified several distinct lineages ofSynechococcalesspanning Subclusters 5.2 and 5.3. Distinct genotypic clusters mapped to phenotypically similar flow populations, suggesting that there may not be a clear one‐to‐one mapping between genotypes and phenotypes. This suggests genome‐level differentiation between lakes but some degree of phenotypic convergence in pigment characteristics. Our results demonstrate that ecological selection for locally adapted populations may outpace homogenization by physical transport in this interconnected system. Given the reliance of the Lakes on in situ primary production as a source for organic carbon, this work sets the foundation to test how the community structure of small primary producers corresponds to biogeochemical and food web functions of the Great Lakes and other freshwater systems.
