摘要： 北极新奥尔松地区(78°55′N, 11°56′E)位于北极圈附近的斯瓦尔巴德群岛上, 属于高北极地区。至今, 对该地区大型真菌独特的物种多样性和生态分布规律研究较少。本研究以2019年(7—8月期间)采集自该地区的48份大型真菌标本为材料, 通过形态特征和分子序列分析, 鉴定出21种, 隶属于1目、7科、10属, 其中锈健孔菌(Arrhenia rustica)为斯瓦尔巴德群岛新记录种。此外, 结合已报道的文献资料进行区系分析, 显示该地区大型真菌物种具有明显的泛北极分布特征, 以北温带-北极分布和北寒带分布成分为主。本研究丰富了对北极新奥尔松地区大型真菌物种多样性的认识, 为研究气候变化对北极真菌物种多样性的影响提供了基础数据。

Abstract: The Ny-Ålesund Region (78°55′N, 11°56′E) is located on the western coast of Svalbard, which is the northernmost settlement in the Arctic. To date, the diversity and ecological distribution of macrofungi in this region have been poorly studied. In this study, we collected a total of 48 macrofungal samples in this region during July/August 2019. They were identified as 21 species belonging to one order, seven families, and 10 genera based on morphological characteristics and molecular sequence analysis. One species, Ar-rhenia rustica, was found for the first time in the Svalbard Islands. The floristic analysis showed that the macrofungal species in the region had obvious holarctic distributions as species with North-Temperate and Arctic distributions and North-Frigid distributions were the main geographical components. This study enriches the understanding of macrofungal diversity in the Ny-?lesund Region and provides basic data for studying the impact of climate change on fungal diversity in the Arctic tundra.
