在水生生态学越来越多的注意力集中在微生物的生态学模式，以及这些潜在的模式是否可以在一般生态学的框架内解释。长期以来，微生物学家的信条“一切都无处不在，但环境选择”表明，分散并不限制微生物，但环境是微生物群落组成的主要决定因素。分子技术的进步提供了新的证据，证明微生物中存在着生物地理学模式，而扩散限制实际上可能起着重要作用，然而最近使用极深测序的研究预测，一切确实无处不在。使用“入侵”的海洋附着植物Prymnesium parvum的长期实地研究，我们在美国南部的亚热带蓄水的P. parvum的环境生态位的特点。我们的分析有助于越来越多的证据表明，环境条件的主要作用，但不是分散，在这个全球重要的微生物在全湖的丰度和季节性开花模式。
Growing attention in aquatic ecology is focusing on biogeographic patterns in microorganisms and whether these potential patterns can be explained within the framework of general ecology. The long-standing microbiologist's credo 'Everything is everywhere, but, the environment selects' suggests that dispersal is not limiting for microbes, but that the environment is the primary determining factor in microbial community composition. Advances in molecular techniques have provided new evidence that biogeographic patterns exist in microbes and that dispersal limitation may actually have an important role, yet more recent study using extremely deep sequencing predicts that indeed everything is everywhere. Using a long-term field study of the 'invasive' marine haptophyte Prymnesium parvum, we characterize the environmental niche of P. parvum in a subtropical impoundment in the southern United States. Our analysis contributes to a growing body of evidence that indicates a primary role for environmental conditions, but not dispersal, in the lakewide abundances and seasonal bloom patterns in this globally important microbe.
