Cyanobacteria are oxygenic photosynthetic organisms that are prevalent in freshwater and marine ecosystems. A proportion of the cyanobacteria in a given locality are known to be introduced from other regions and are able to cause harmful cyanobacterial blooms. However, the processes by which cyanobacteria is relocated are not well described. This review presents the various natural and anthropogenic methods of cyanobacterial transport, with emphasis on the dispersal of problematic taxa. Natural mechanisms for transport of cyanobacteria include meteorological phenomena such as dust storms and tsunamis, which facilitate the long-distance transport of cyanobacteria through the air and rafting debris in oceans, respectively. Cyanobacteria can also be transported by animals such as worms, seabirds and planktivorous fish. The influence of anthropogenic activities on cyanobacterial distributions is also discussed, with focus on transport through international shipping and on rafting surfaces provided by plastic pollution. In this study, a total of 150 species of cyanobacteria from 64 genera were identified to be transported across a combination of natural and anthropogenic methods. As cyanobacteria are organisms that are prevalent in many ecosystems, an understanding of these transport processes will allow for improved assessment and monitoring of introduced toxic cyanobacterial species.

蓝藻的自然和人为传播:综述

蓝藻是淡水和海洋生态系统中普遍存在的含氧光合生物。已知特定地区的一部分蓝藻是从其他地区引入的,能够导致有害的蓝藻大量繁殖。然而,蓝藻重新定位的过程并没有得到很好的描述。这篇综述介绍了蓝藻运输的各种自然和人为方法,重点是有问题的分类群的传播。蓝藻运输的自然机制包括沙尘暴和海啸等气象现象,它们分别促进蓝藻通过空气和漂流海洋中的碎片进行长距离运输。蓝藻也可以被蠕虫、海鸟和浮游鱼类等动物传播。还讨论了人为活动对蓝藻分布的影响,重点是通过国际航运的运输和塑料污染提供的漂流表面。在这项研究中,共有来自 64 个属的 150 种蓝藻被鉴定为通过自然和人为方法的组合运输。由于蓝藻是许多生态系统中普遍存在的生物,因此了解这些运输过程将有助于改进对引入的有毒蓝藻物种的评估和监测。共确定了 64 个属的 150 种蓝藻,它们可以通过自然和人为方法相结合进行运输。由于蓝藻是许多生态系统中普遍存在的生物,因此了解这些运输过程将有助于改进对引入的有毒蓝藻物种的评估和监测。共确定了 64 个属的 150 种蓝藻,它们可以通过自然和人为方法相结合进行运输。由于蓝藻是许多生态系统中普遍存在的生物,因此了解这些运输过程将有助于改进对引入的有毒蓝藻物种的评估和监测。
