“…This suggests that other factors control the microbiome population. The structure of the microbial community was partially dependent on pH, soil water content, and the content of C and N. Moreover, soil microorganisms play a key role in release of nutrients from minerals, thereby forming a new environment not only for themselves, but also directly for plants (Górniak et al 2017). The number of culturable microorganisms was very high, which implies that they were considerably involved in the transformation of compounds containing C, N, and P, as well as in the availability of heavy metals.…”

“…Also, there may be a further decrease in slope associated with an increase in Fe due to the frontal recession of Werenskiöldbreen and exposure of fresh mineral surfaces. A decrease in the chlorite:mica ratio and an increase in the abundance of mineral weathering bacteria in the proglacial zone implies that Al release to meltwater from weathering of chlorite will decrease as well (Górniak, Marszałek, Kwaśniak‐Kominek, Rzepa, & Manecki, ; Kabala & Zapart, ). Our hydrochemical data (slopes and intercepts of Al vs. Fe plot, Figure ) and an increase in the saturation index with respect to chlorite (Tables , ) confirm the drop in chlorite weathering leading to reduced Al release.…”

The aluminium (Al) cycle in glacierised basins has not received a great deal of attention in studies of biogeochemical cycles. As Al may be toxic for biota, it is important to investigate the processes leading to its release into the environment. It has not yet been ascertained whether filterable Al (passing through a pore size of 0.45 μm) is incorporated into biogeochemical cycles in glacierised basins. Our study aims to determine the relationship between the processes bringing filterable Al and glacier‐derived filterable nutrients (particularly Fe and Si) into glacierised basins. We investigated the Werenskiöldbreen basin (44.1 km2, 60% glacierised) situated in SW Spitsbergen, Svalbard. In 2011, we collected meltwater from a subglacial portal at the glacier front and at a downstream hydrometric station throughout the ablation season. The Al concentration, unchanged between the subglacial system and proglacial zone, reveals that aluminosilicate weathering is a dominant source of filterable Al under subglacial conditions. By examining the Al:Fe ratio compared with pH and the sulphate mass fraction index, we found that the proton source for subglacial aluminosilicate weathering is mainly associated with sulphide oxidation and, to a lesser degree, with hydrolysis and carbonation. In subglacial outflows and in the glacial river, Al and Fe are primarily in the forms of Al(OH)4‐ and Fe(OH)3. The annual filterable Al yield (2.7 mmol m‐2) was of a magnitude similar to that of nutrients such as filterable Fe (3.0 mmol m‐2) and lower than that of dissolved Si (18.5 mmol m‐2). Our results show that filterable Al concentrations in meltwater are significantly correlated to filterable and dissolved glacier‐derived nutrients (Fe and Si, respectively) concentrations in glaciers worldwide. We conclude that a potential bioavailable Al pool derived from glacierised basins may be incorporated in biogeochemical cycles, as it is strongly related to the concentrations and yields of glacier‐derived nutrients.

“…Microbial community structure is strongly conditioned by the successional stage, deglaciation time, water content, plants, spruce leachate, and the C and N contents of the foreland soil (Tscherko et al, 2004;Noll and Wellinger, 2008;Göransson et al, 2011;Knelman et al, 2012Knelman et al, , 2018Górniak et al, 2017;Kim et al, 2017;Bai et al, 2020). Most of the above reports did not include rhizosphere soil, and these studies were on elevations of < 1,000 m (Knelman et al, 2012(Knelman et al, , 2018Kim et al, 2017), 1,780 m (Górniak et al, 2017), 1,920-2,054 m (Göransson et al, 2011), 1,950-2,050 m (Noll and Wellinger, 2008), 2,280-2,450 m (Tscherko et al, 2004, and 2,951 m at glacier termini (Bai et al, 2020). The effects of the highelevation environmental parameters on the glacier foreland prokaryotic community were seldom found in field research.…”

“…Microbial succession is highly correlated with soil C and nitrogen (N) contents along the deglaciation chronosequence (Zumsteg et al, 2012), and the microbial communities are the main drivers that build the soil organic matter pool, expediting pedogenesis for ecosystem succession (Sun et al, 2016). Early soil formation processes should be related to the composition of the microbial communities, the primary substrate structure, and available water (Górniak et al, 2017). The establishment of pioneering microbial communities is the key determinant of deglaciated soil development and its ecosystem function and stability (Schmidt et al, 2008;Kabala and Zapart, 2012) and facilitates the colonization of pioneering plants (Bradley et al, 2014).…”

Prokaryotic Community Succession in Bulk and Rhizosphere Soils Along a High-Elevation Glacier Retreat Chronosequence on the Tibetan Plateau

Early colonization and succession of soil microbial communities are essential for soil development and nutrient accumulation. Herein we focused on the changes in pioneer prokaryotic communities in rhizosphere and bulk soils along the high-elevation glacier retreat chronosequence, the northern Himalayas, Tibetan Plateau. Rhizosphere soils showed substantially higher levels of total organic carbon, total nitrogen, ammonium, and nitrate than bulk soils. The dominant prokaryotes were Proteobacteria, Actinobacteria, Acidobacteria, Chloroflexi, Crenarchaeota, Bacteroidetes, and Planctomycetes, which totally accounted for more than 75% in relative abundance. The dominant genus Candidatus Nitrososphaera occurred at each stage of the microbial succession. The richness and evenness of soil prokaryotes displayed mild succession along chronosequene. Linear discriminant analysis effect size (LEfSe) analysis demonstrated that Proteobacteria (especially Alphaproteobacteria) and Actinobacteria were significantly enriched in rhizosphere soils compared with bulk soils. Actinobacteria, SHA_109, and Thermoleophilia; Betaproteobacteria and OP1.MSBL6; and Planctomycetia and Verrucomicrobia were separately enriched at each of the three sample sites. The compositions of prokaryotic communities were substantially changed with bulk and rhizosphere soils and sampling sites, indicating that the communities were dominantly driven by plants and habitat-specific effects in the deglaciated soils. Additionally, the distance to the glacier terminus also played a significant role in driving the change of prokaryotic communities in both bulk and rhizosphere soils. Soil C/N ratio exhibited a greater effect on prokaryotic communities in bulk soils than rhizosphere soils. These results indicate that plants, habitat, and glacier retreat chronosequence collectively control prokaryotic community composition and succession.
