By using data collected during a continuous circumnavigation of the Southern Hemisphere, we observed clear patterns in the population-genetic structure of Prochlorococcus, the most abundant photosynthetic organism on Earth, between and within the three Southern Subtropical Gyres. The same mechanisms that were previously invoked to account for the vertical distribution of ecotypes at local scales accounted for the global (horizontal) patterns we observed. Basin-scale and seasonal variations in the structure and strength of vertical stratification provide a basis for understanding large-scale horizontal distribution in genetic and physiological traits of Prochlorococcus, and perhaps of marine microbial communities in general.
通过利用在一次环绕南半球的连续航行中收集的数据，我们观察到了地球上最丰富的光合生物——原绿球藻在三个南亚热带环流之间及内部的种群遗传结构中的清晰模式。先前用于解释局部尺度上生态型垂直分布的相同机制，也解释了我们所观察到的全球（水平）模式。垂直分层结构和强度的盆地尺度及季节变化，为理解原绿球藻以及可能一般海洋微生物群落的遗传和生理特征的大规模水平分布提供了基础。
