Effects of Warming on Microbial Community Characteristics in the Soil Surface Layer of Niaodao Wetland in the Qinghai Lake Basin

Lakeshore wetlands are important terrestrial ecosystems worldwide, and the lakeshore of Tibetan Plateau sensitive to climate change. Therefore, in context global warming, studying effects temperature rise on surface soil microbial communities is essential for wetland biodiversity conservation. In this study, we used metagenomic sequencing examine changes structure their metabolic pathways Niaodao (NLW) Qinghai Lake at 1.2 °C warming. Under natural control warming conditions, Proteobacteria Actinobacteria were most dominant bacterial phyla, Ascomycota Basidiomycota predominant fungal phyla. Soil pH, electrical conductivity, affected relative abundances microbes. Effect size estimation a linear discriminant analysis revealed 11 differential between conditions. Warming considerably enhanced peptidoglycan biosynthetic but inhibited ATP-binding cassette transporter pathway. treatment α-diversity indices, with an increase Shannon, Chao1, richness indices decrease Simpson index compared Analysis similarities showed significant differences samples. Overall, altered community increased diversity abundance NLW.
