“…Kim et al [18] also reported C:N ratios ranging from 13.2 to 21.3 in mature soil outside the glacier moraine in Ny-Ålesund. In addition, iron (Fe 2+ ) ranged from 7.54 to 17.65 mg/g, which was lower than that reported by previous research (30.2 to 39.3 mg/g) on mature soils in Ny-Ålesund [8].…”

“…Furthermore, land-use types can shape soil microbial communities by modulating community structure [ 7 ]. These soil microbial communities modulate vegetation structure during colonization [ 8 ], and plants interact with the microbial community through root exudates and litter inputs, which are particularly important in nutrient-poor soil [ 9 ]. Rhizodeposition, microbial activity, redox reactions, root nutrient uptake, and CO 2 production all distinguish pioneer plant rhizosphere soil from bulk soil [ 10 - 12 ].…”

“…Rhizodeposition, microbial activity, redox reactions, root nutrient uptake, and CO 2 production all distinguish pioneer plant rhizosphere soil from bulk soil [ 10 - 12 ]. Understanding the spatial distribution of soil microbial communities is essential for determining how these communities contribute to biogeochemical cycling, plant colonization, and soil development in the Arctic region [ 8 , 13 , 14 ].…”

“…Soil microbial community diversity in the Arctic has been investigated for several decades, with recent research on microbial community structure and function enabled by advancements in genomics [ 8 ]. In particular, next-generation sequencing is an important technique in ecology to sequence multiple samples and explore bacterial species diversity, either by targeting the 16S rRNA gene or by directly sequencing genomic DNA or RNA [ 15 , 16 ].…”

had a relatively higher abundance of Bacteroidetes and Firmicutes. On the other hand, Acidobacteria was more prevalent in seashore-adjacent samples. The relative abundance of Proteobacteria and Acidobacteria decreased toward higher soil pH, whereas that of Bacteroidetes and Firmicutes was positively correlated with soil pH. Our results suggest that soil bacterial community dissimilarity can be driven by spatial heterogeneity in deglaciated mature soil. Furthermore, these results indicate that soil microbial composition and relative abundance are more affected by soil pH, an abiotic factor, than plant species, a biotic factor.

“…Few previous studies have compared the intertidal soil with the subtidal soil, while most studies in the Ny-Ålesund area have focused on soil, sediment or topsoil in a single characteristic area [ 14 , 15 , 16 ]. All these studies can only prove the influence of environmental factors on bacterial community at the sampling site, which is not enough to explain the relationship between environmental factors and bacterial community change in Ny-Ålesund area.…”

The Study of Soil Bacterial Diversity and the Influence of Soil Physicochemical Factors in Meltwater Region of Ny-Ålesund, Arctic

Global climate change has caused the changes of the ecological environment in the Arctic region, including sea ice melting, runoff increase, glacial lake expansion, and a typical meltwater area has formed in the Arctic coastal area. In this study, the meltwater areas near six different characteristic areas of Ny-Ålesund in 2018 were taken as the research objects, and high-throughput sequencing of V3–V4 regions of all samples were performed using 16S rDNA. Among the soil samples of six glacial meltwater areas in Ny-Ålesund, Arctic, the meltwater area near the reservoir bay had the highest bacterial abundance, and the meltwater area near the sand had the lowest one. The dominant phyla in soil samples were Proteobacteria, Actinobacteria, Acidobacteria. The NH4+-N content in intertidal soil was higher than that in subtidal soil. Through WGCNA analysis and LEFSE analysis, it was found that the core bacteria significantly related to NH4+-N were basically distributed in the intertidal area. For example, Nitrosomonadaceae, Nitrospira and Sphingomonas were the core bacteria showed significant different abundance in the intertidal area, which have the ability to metabolize NH4+-N. Our findings suggest that NH4+-N plays an important role in soil bacterial community structure in the Arctic meltwater areas.

It has long been recognized that pH mediates community structure changes in glacier foreland soils. Here, we showed that pH changes resulted from plant colonization. Plant colonization reduced pH and increased soil organic carbon, which increased bacterial diversity, changed the community structure of both bacteria and fungi, enhanced environmental filtering, and improved microbial network disturbance resistance.
