北极土壤生态系统的功能对全球气候至关重要，而氮(N)是这些环境中的主要限制性养分。这项研究评估了氮含量的变化对北极湖地区(伦敦岛，斯瓦尔巴群岛)古生物群落多样性和组成的影响。对16S rRNA基因进行了测序，以研究古菌群落组成。首先，土壤样品和沉积物样品在地球化学性质和古生物群落组成方面存在显著差异。在9个土壤样品中，塔乌姆考古纲是一个丰富的门。此外，在三个沉积物样品中，Eurya chaeota、Woesearchaeota和Bathya chaeota都是显著丰富的门。其次，研究发现，冻土融化和积雪引起的地表径流改变了土壤的化学性质。然后，地球化学性质的变化影响了土壤中古生物群落的组成。此外，基于距离的冗余度分析表明，NH4+-N(p<；0.05)和水分含量是与古生物群落组成相关最显著的因素。我们的研究表明，氮含量在土壤古生菌群落中起着重要的作用。此外，古细菌在北极湖地区的碳氮循环中起着重要的作用。
The function of Arctic soil ecosystems is crucially important for the global climate, and nitrogen (N) is the major limiting nutrient in these environments. This study assessed the effects of changes in nitrogen content on archaeal community diversity and composition in the Arctic lake area (London Island, Svalbard). A total of 16S rRNA genes were sequenced to investigate archaeal community composition. First, the soil samples and sediment samples were significantly different for the geochemical properties and archaeal community composition. Thaumarchaeota was an abundant phylum in the nine soil samples. Moreover, Euryarchaeota, Woesearchaeota, and Bathyarchaeota were significantly abundant phyla in the three sediment samples. Second, it was found that the surface runoff caused by the thawing of frozen soil and snow changed the geochemical properties of soils. Then, changes in geochemical properties affected the archaeal community composition in the soils. Moreover, a distance-based redundancy analysis revealed that NH4+–N (p < 0.05) and water content were the most significant factors that correlated with the archaeal community composition. Our study suggests that nitrogen content plays an important role in soil archaeal communities. Moreover, archaea play an important role in the carbon and nitrogen cycle in the Arctic lake area.
