Microbial Biodiversity of the Hawaiian Anchialine EcosystemAnchialine environments are coastal land-locked bodies of brackish water exhibiting tidal fluctuations due to their simultaneous subterranean connections to the ocean and groundwater aquifers. Home to often regionally endemic organisms, this ecosystem type is increasingly becoming endangered due to anthropogenic pressures. This is especially true in the Hawaiian Islands, which has the only natural anchialine environments in the US but where 90% have already been lost or degraded. Thus, the opportunity to document the biodiversity contained within Hawaii's anchialine ecosystem is rapidly dwindling. While microbes are essential to the function of this ecosystem, they have so far been poorly characterized. To rectify this, this project will utilize high-throughput DNA sequencing and environmental data to identify factors influencing Hawaii's anchialine microbial community composition across space and time as well as quantify how perturbation alters community structure and function. Furthermore, a Hawaiian Anchialine Microbial (HAM) repository will be established to maintain access to these microbial communities given their potential for containing taxa of basic research and/or applied scientific value.Overall, this project will broaden the basic biological knowledge for one of Hawaii's least studied and potentially most endangered ecosystems. Additionally, undergraduates and a graduate student from underrepresented groups will be trained and mentored over the work's duration. Federal and State of Hawaii governmental agencies have also identified information to be developed by the proposed work as having significant value in the future implementation of anchialine environment management strategies in the Hawaiian Islands. Lastly, Hawaiian anchialine environments and their biota will be utilized as a tool for educating K-12 students, teachers, and the general public in Hawaii and Alabama on a range of scientific topics

夏威夷 Anchialine 生态系统的微生物生物多样性 Anchialine 环境是沿海内陆咸水水体，由于同时与海洋和地下水含水层存在地下连接，因此表现出潮汐波动。这种生态系统类型通常是区域性特有生物的家园，由于人为压力，它正日益受到威胁。夏威夷群岛尤其如此，这里拥有美国唯一的自然近岸环境，但 90% 的近岸资源已经消失或退化。因此，记录夏威夷近岸生态系统中生物多样性的机会正在迅速减少。虽然微生物对于这个生态系统的功能至关重要，但迄今为止对它们的描述还很有限。为了纠正这个问题，该项目将利用高通量 DNA 测序和环境数据来确定影响夏威夷 anchialine 微生物群落在空间和时间上的组成的因素，并量化扰动如何改变群落结构和功能。此外，鉴于这些微生物群落具有包含基础研究和/或应用科学价值的分类群的潜力，将建立夏威夷 Anchialine 微生物 (HAM) 存储库，以保持对这些微生物群落的访问。总体而言，该项目将拓宽夏威夷一种微生物的基本生物学知识。研究最少且可能最濒危的生态系统。此外，来自代表性不足群体的本科生和研究生将在工作期间接受培训和指导。联邦和夏威夷州政府机构还确定了拟议工作要开发的信息对于夏威夷群岛未来实施安奇阿林环境管理战略具有重要价值。最后，夏威夷的近海环境及其生物群将被用作对夏威夷和阿拉巴马州的 K-12 学生、教师和公众进行一系列科学主题教育的工具
