温带湖泊的混合和分层变化影响了浮游生物群落的分布、活动、丰度和多样性。研究了蒙大拿州富营养化平头湖浮游微生物（包括细菌和古生菌）组成的时间和垂直变化。使用包括16S rRNA基因测序和流式细胞术测定细胞丰度在内的多种方法，我们发现微生物群落在时间尺度上对分层和混合的变化有反应，从偶然的（天的尺度）到季节性的。然而，这种物理动态的影响在不同的分类群之间是不同的，可能反映了分类群对与分层和混合相一致的环境变化的特定响应（例如，光有效性和养分供应）。在早春期间，相对较短（< 7 d）的分层和混合间歇期影响了特定微生物分类群的垂直分布，特别是蓝藻。这些事件突出了与湖泊分层和混合相关的高频变化的生物反应的时间尺度，特别是在早春生长季节的过渡期间。
Temperate lakes experience variation in mixing and stratification that affects the distributions, activities, abundances, and diversity of plankton communities. We examined temporal and vertical changes in the composition of planktonic microorganisms (including Bacteria and Archaea) in oligotrophic Flathead Lake, Montana. Using a combination of approaches that included 16S rRNA gene sequencing and flow cytometric determination of cell abundances, we found that the microbial community was responsive to variations in stratification and mixing at time scales ranging from episodic (scale of days) to seasonal. However, the impact of such physical dynamics varied among taxa, likely reflecting taxa‐specific responses to environmental changes that coincide with stratification and mixing (e.g., light availability and nutrient supply). During the early spring, periods of relatively short‐term (< 7 d) intermittency in stratification and mixing influenced the vertical distributions of specific microbial taxa, notably including the cyanobacteria. These events highlight time scales of biological responses to high‐frequency variations associated with lake stratification and mixing, particularly during the transition to the growing season in the early spring.
