“…Dong et al [13] showed that the resulting variation in soil organic carbon content in wetlands was higher by taking microorganisms into the assessment of "soil community" randomness. Yu et al [14] found that fungal residues (FNCs) were an important source of organic carbon in wetland sediments. Higher microbial biomass (MBC) and higher microbial residues (MNC) favor organic carbon storage.…”

With the development of global industrialization, carbon neutrality has become an issue that we must be paid attention to. Microorganisms not only have an important impact on the carbon chemical cycle between the Earth's biosphere and biogeography but also play a key role in maintaining the global organic carbon balance. Wetlands are the main reservoir of organic carbon in the mainland of China, and wetland carbon sinks are indispensable for China to achieve the goal of “dual carbon,” and China has taken the consolidation and improvement of wetland carbon sink capacity as an important part of the carbon peaking action plan. As a unique low‐latitude, high‐altitude seasonal plateau wetland in China, Napahai shows high research value. However, the role of microbes in maintaining dissolved organic carbon balance in this area has not been reported. In the study, six carbon fixation genes, accA, aclB, acsA, acsB, cbbL, and rbcL, were analyzed based on metagenomics to elucidate the rich genetic diversity, uniqueness and differences in the Napahai plateau wetland. It was found that the microbial diversity in the Napahai plateau wetland was different from other habitats. In addition, the aclB gene, a rare taxon with high genetic diversity and rich species in the Napahai plateau wetland, played a key role in the microbial metabolic pathway. Finally, the construction of a metabolic pathway through the Kyoto encyclopedia for genes and genomes revealed the contribution of microbes to carbon fixation and the role of microbes in maintaining the organic carbon balance of the Napahai plateau wetland.

“…Retreating glaciers expose a large mass of frequently oligotrophic sediment that has been previously locked under the ice [ 3 , 4 ]. Microorganisms are the pioneer colonizers of newly exposed ground (glacier foreland) [ 5 , 6 ], their community dynamics determine ecosystem functions, which ultimately influence the carbon transformation processes [ 7 , 8 , 9 ]. Glacial foreland microbial flora comprises bacteria, fungi, and microeukaryotes [ 5 , 6 ].…”

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.
