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

夏威夷阿基亚林生态系统的微生物生物多样性阿基亚林环境是沿海的内陆微咸水水体，由于它们同时与海洋和地下水含水层有地下联系，所以表现出潮汐波动。这种生态系统通常是地区性特有生物的家园，由于人为压力，这种生态系统类型正日益濒临灭绝。这在夏威夷群岛尤其如此，那里有美国唯一的自然珊瑚环境，但那里90%的环境已经消失或退化。因此，记录夏威夷珊瑚礁生态系统中包含的生物多样性的机会正在迅速减少。虽然微生物对这个生态系统的功能是必不可少的，但到目前为止，它们的特征还很差。为了纠正这一点，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棘突微生物群落组成的因素，并量化扰动如何改变群落结构和功能。此外，考虑到这些微生物群落包含基础研究和/或应用科学价值的分类群的潜力，将建立一个夏威夷珊瑚礁微生物(HAM)储存库，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研究最少、可能最濒危的生态系统之一的基本生物学知识。此外，来自代表性不足群体的本科生和研究生将在整个工作期间接受培训和指导。夏威夷联邦和州政府机构还确定，拟议工作将提供的信息对今后在夏威夷群岛执行环境管理战略具有重要价值。最后，夏威夷的珊瑚礁环境及其生物群将作为一种工具，在夏威夷和阿拉巴马州的K-12学生、教师和普通公众中进行一系列科学主题的教育
