The Florida Keys, a delicate archipelago of sub-tropical islands extending from the south-eastern tip of Florida, host the vast majority of the only coral barrier reef in the continental United States. Abiotic as well as microbial components of the surrounding waters are pivotal for the health of reef habitats, and thus could play an important role in understanding the development and transmission of coral diseases in Florida. In this study, we analyzed microbial community structure and abiotic factors in waters around the Florida Reef Tract. Both bacterial and eukaryotic community structure were significantly linked with variations in temperature, dissolved oxygen, and total organic carbon values. High abundances of copiotrophic bacteria as well as several potentially harmful microbes, including coral pathogens, fish parasites and taxa that have been previously associated with Red Tide and shellfish poisoning were present in our datasets and may have a pivotal impact on reef health in this ecosystem.
佛罗里达群岛是一个从佛罗里达州东南端延伸出来的亚热带岛屿组成的精致群岛，这里拥有美国大陆唯一的珊瑚礁屏障的绝大部分。周围水域的非生物成分以及微生物成分对珊瑚礁栖息地的健康至关重要，因此在理解佛罗里达州珊瑚疾病的发展和传播方面可能发挥重要作用。在这项研究中，我们分析了佛罗里达礁区周围水域的微生物群落结构和非生物因素。细菌和真核生物群落结构均与温度、溶解氧和总有机碳值的变化显著相关。我们的数据集中存在大量的富营养细菌以及几种潜在有害微生物，包括珊瑚病原体、鱼类寄生虫以及先前与赤潮和贝类中毒有关的分类群，它们可能对该生态系统中的珊瑚礁健康产生关键影响。
