海洋真菌在极地地区的研究严重不足。我们使用分子鉴定的文化，研究真菌栖息在50潮间带和海底日志沿着挪威北部海岸。目的是探讨分类和生态多样性，并检查形成海洋木材栖息真菌群落的因素。分析的577个纯培养物基于97%的ITS序列相似性聚类为147个操作分类单位（OTU）。子囊菌门占主导地位，但属于担子菌门，毛霉亚门和壶菌门的OTU也被分离出来。9个OTU不能被分配到任何真菌门。几乎一半的OTU被认为是非海洋的。挪威巴伦支海海岸的西部和东部居住着不同的社区。地理，基层和网站一级变量有助于塑造这些社区。我们以前被忽视的真菌群落的特点是在一个研究不足的地区，发现了高多样性，并报告了许多类群的第一次从海洋环境。(C)2014作者由爱思唯尔有限公司出版。保留所有权利。
Marine fungi are severely understudied in the polar regions. We used molecularly identified cultures to study fungi inhabiting 50 intertidal and sea-floor logs along the North Norwegian coast. The aim was to explore the taxonomic and ecological diversity and to examine factors shaping the marine wood-inhabiting fungal communities. The 577 pure cultures analyzed clustered into 147 operational taxonomic units (OTUs) based on 97 % ITS sequence similarity. Ascomycota dominated, but OTUs belonging to Basidiomycota, Mucoromycotina and Chytridiomycota were also isolated. Nine OTUs could not be assigned to any fungal phylum. Almost half of the OTUs were considered non-marine. The western and eastern part of the Norwegian Barents Sea coast hosted different communities. Geography, substratum and site level variables contributed to shaping these communities. We characterized a previously overlooked fungal community in a poorly studied area, discovered high diversity and report many taxa for the first time from the marine environment.
